The Space Race part 7: Why did the Russians lose, in fact, why didn’t they even manage to finish the race?

This is the seventh in a series of posts in celebration of the fiftieth anniversary of Apollo 11 and man’s first landing on the Moon. In this post I will discuss the Soviet Union’s Lunar program taking a detailed look at the factors and decisions that not only enabled the American Apollo program to achieve the first landing on the Moon, but which doomed the Russians to never even achieving a Lunar landing.

Actually back during the 1960s the Soviet Union never even admitted to having a Lunar program, they denied they were even in a race. The Americans may have committed themselves to getting to the Moon by 1970, the Russians said, but we will continue to explore space in our own direction at our own pace.

Even after the Apollo landings the Russians did not admit to having lost anything. Oh, they congratulated the Americans for their achievement. At the same time however they maintained that they were concentrating their efforts toward long-term habitation of Low Earth Orbit (LOE), which they did in the 1970s and 80s with their Salyut and Mir space stations. As far as anyone in the west knew for certain, there never was a space race!

The Soviet Union never admitted to having a Lunar Program claiming instead that they were working on their Salyut Space Station. See here with a Soyuz spacecraft docked (Credit: Pinterest)

In fact the Russians were absolutely determined to get to the Moon first, to beat the Americans. In the 1960-62 time frame the Russians were in the lead in space and they fully intended to stay there. The recognition and respect that the Soviet Union had gathered from their achievements in space only made them hungry for more. More than that they had come to regard the new frontier of space as where their Soviet / Communist system would prove its superiority to decadent capitalism. It was only years later, after of collapse of the Soviet Union that the full extent of the Russian Lunar program finally became public.

One of the problems of the Soviet space program was that their chief designer Sergei Korolev, didn’t get along with Khrushchev (Credit: Roscosmos)

It turned out the Soviet’s had two Lunar programs, and that was probably their first mistake! The larger Russian program was led by their ‘Chief Designer’ Sergei Korolev, the man who had put both Sputnik and Yuri Gagarin into orbit. Korolev knew that he would never have as much money and resources as the United States could spend on Apollo so his plan was a scaled down version of NASA’s program. Korolev’s version of the Saturn V launch vehicle was called the N-1 and would have been capable of sending just about half as much payload out of Earth orbit and on a trajectory to the Moon. See image below.

Because of the reduced capability of his launch vehicle Korolev had to scale down all of the other components of a Lunar mission. A modified 2-man version of the Soyuz spacecraft would carry two cosmonauts to Lunar orbit from where a single-man Lunar lander would take a lone cosmonaut to the Moon’s surface, see images below.

Imagine for a moment if you will what it would have been like to be that lone human being rocketing down to the Moon’s surface. At least Neil Armstrong and Buzz Aldren had each other for support as they went ‘where no man had gone before’. The Russian cosmonaut would have been alone as no other human had ever been.

The second Soviet Lunar program was led by Vladimir Chelomei and would not actually have placed a cosmonaut on the surface of the Moon. Instead Chelomei intended to use his large Proton rocket, originally called the UR-500, to send a two-man Soyuz on a single loop journey around the Moon. If you’re wondering why the Soviet government would even fund a program that wasn’t even intended to go all the way well there were two reasons. First unlike the rockets Korolev built that took days to fuel and were unusable as weapons of war, Chelomei promised a large rocket that used storable fuel and that could be converted into an Intercontinental Ballistic Missile (ICBM). Second, let’s just say that Chelomei was better at playing politics, flattering his bosses on the Politburo, one of his chief assistants was actually the son of Soviet Premier Nikita Kruschev.

In the long run Chelomei’s Proton rocket did become Russia’s most successful heavy lift launch vehicle, placing into orbit the Salyuts, Mir and even modules of the International Space Station (ISS). During the space race however Chelomei just sucked much needed funds away from Korolev’s program.

Eventually Vladimir Chelomei’s Proton rocket proved to be a successful space launch vehicle but during the space race it was just a distraction. (Credit: Wikidata)

Then in January of 1966 the Soviet program suffered the loss of it’s chief designer as Sergei Korolev died on the operating table after entering the hospital for routine surgery for a bleeding polyp in his large intestine. Now Korolev had been sick for years, ever since being sentenced to a gulag by Stalin, and he’d literally worked himself to exhaustion to keep the Soviet space program on top. The precise effect of the loss of one man cannot ever be known but the fact that the Russian space program would experience several major setbacks in the next few years leaves you to wonder what Korolev would have done if he’d not died.

The first disaster occurred just a year later as the Russians launched their new Soyuz spacecraft on its first mission. A catastrophic entangling of the descent parachutes during the landing resulted in the death of cosmonaut Vladimir Komarov. Since the Soyuz spacecraft was a central component of both Soviet Lunar programs the tragedy of Soyuz one was a major blow.

Worse was to come for in 1967 the first two test launches of Chelomei’s Proton launch vehicle both ended in failure while in February of 1969 the first test launch of Korolev’s monster N-1 rocket exploded only seconds after launch.

With the failures of the first tests of the Soviet heavy launch vehicles the race over, Apollo 11 would land successfully on the Moon just five months later. Still, the Russians could have kept trying; coming in second is better than failing to finish isn’t it.

In fact they did keep trying, testing their huge N-1 rocket three more times, with each test resulting in the total destruction of the rocket less than a minute after launch. After the final failure on 23 November of 1972 the entire Soviet Manned Lunar was not only canceled but orders went out to deny that it had ever existed.

So why did the Soviet Union never get to the Moon? Was it the political infighting between two Lunar programs? Was it the death of Korolev? Or did the Americans simply outspend their cold war adversaries? A bit of all three if you want my opinion. As the space race came to its end there was only one competitor left, the first man on the Moon would be an American.

Movie Review: Godzilla, King of the Monsters!

Before I begin with my review of ‘Godzilla, King of the Monsters’ I feel I need to make a full disclosure. Godzilla and I are the same age (His premiere was about a month and a half after mine!) , we’ve known each other a very long time, in fact we grew up on different continents together!

For years Godzilla was nothing more than a guy in a rubber suit (Credit: Toho Studios)

O’k, I’ll stop being silly. The plain fact is however that I have seen every Godzilla movie, as a kid I spent many a Saturday afternoon watching monster movies and one of my favourite childhood memories is that of dragging my father to the movie theater to see ‘King Kong versus Godzilla’ back in 1962. So I guess you’d have to say that I’m predisposed to giving a good review to any movie starring Godzilla and his ‘friends’. Hey, just giving you a warning.

Was King Kong versus Godzilla the most titanic fight of all time. As an 8 year old I thought so! (Credit: Toho Studios)

Now the plot of ‘Godzilla, King of the Monsters, that is the story that the human actors are involved in is both convoluted and quite frankly, silly. That’s to be expected, you don’t go to a Godzilla movie to see a well-developed story and good acting, you go to watch the monsters stomp on things and fight each other!

Anyway according to the story it seems that for the last 60 years a secret organization called Monarch has been keeping several dozen ‘titans’ captive. (Why they’re called titans in the movie while the movie’s title explicitly says monsters is never explained!) The only titan not contained by Monarch as the movie begins is Godzilla himself. Anyway the government says the monsters, excuse me, titans are dangerous and should be destroyed.

However there are also those who say it is humanity that is dangerous. We are destroying this planet with our pollution and greenhouse gasses and the titans are Earth’s way of restoring the balance. They want the titan’s released so that they can do their job, what exactly that job is however, is never really explained.

In a Godzilla Movie the humans are really just an afterthought! (Credit: Warner Brothers)

The action of the movie starts when a group of eco-terrorists, with some help from inside Monarch, succeed in stealing a device that allows them to control the titans and they proceed to start to releasing them but something goes wrong. (How could anything go wrong? They’re just releasing dozens of monsters hundreds of meters tall all over the World! Nothing dangerous in that.)

The Eco-Terrorists cause all the trouble (Credit: Warner Brothers)

As I said, you don’t go to a Godzilla movie to see what the humans are doing, you go to watch the monsters fight each other; in particular you go to watch Godzilla fight Ghidorah, the three headed monster. These two monsters have been enemies since 1964 and their enmity for each other hasn’t mellowed with the years. The fights scenes between these two should be the highlights of the movie.

Should be, but it’s precisely here that ‘Godzilla, the King of the Monsters’ disappoints. This movie really needed the absolute best CGI possible in order to make the monsters seem as real as possible. In fact however the CGI in ‘Godzilla, King of the monsters’ is not nearly as good as in the recent ‘Avengers’ or other SF / Fantasy films. A sure sign of this is the way so many scenes are filmed with a bluish hue to them. Studio’s do that in order to cut down on the effort, manpower and computer time, needed to give every different object in a shot it’s own individual colour. Just make everything kinda bluish and it’ll be cheaper!

When Godzilla fights Ghidorah does everything have to be tinted blue? (Credit: Warner Brothers)

Still in the end Godzilla does get to fight Ghidorah and to make things a little interesting their final battle takes place in Fenway Park, home to the Boston Red Sox and famous for its close but tall left field wall known as the ‘Big green Monster’! I hope I’m not giving the movie’s ending away by pointing out that it is called ‘Godzilla, King of the Monsters’.

Rodan (l) and Mothra (r) also appear as Ghidorah’s and Godzilla’s respective sidekicks (Credit: Warner Brothers)

The studio behind ‘Godzilla, King of the Monsters’ is Warner Brothers who hope to create a monster universe similar to Disney’s Marvel universe. ‘King of the Monsters is actually the third film in the series after 2014’s ‘Godzilla’ and 2017’s ‘Kong of Skull Island’. The next film is supposed to be ‘Godzilla versus Kong’, scheduled for release in 2020 but I really hope they put a little more effort into that film. I’d hate to come away from seeing that movie thinking that ‘King Kong versus Godzilla’ from my childhood was a better-made film!

 

 

Would you be willing to eat lab-grown insect meat in order to end World hunger? Some scientists think that might be the way to do it!

Throughout human history it has always seemed as though whenever advances in our technology have allowed us to increase the amount of food we produce, we increase our population just enough to keep a sizable fraction of our species hungry. Today the problem has become even worse as our agriculture is now using up most of the planet’s land area, we are over fishing the oceans, fertilizer runoff into the rivers and oceans is killing aquatic life while raising livestock is a big contributor to global warming. And we still can’t feed all 7 billion of us!

World Hunger Map for 2014 (Credit: Matador Network)

There are several technical advances in agricultural science that have been suggested as possible solutions to this problem: Vertical farming in factories to make better use of the land (see my post of 22 April 2017), Genetically Modified Organisms (GMOs) to develop crops that grow faster with less water and fertilizer (see my post of 12 January 2019), and cultured meat to eliminate the wastage of producing bones, hide and other unusable parts of an animal (see my post of 7 April 2018).

Vertical Farming can produce many times as much food on the same area as traditional farming (Credit: USDA)
Lab Grown or Cultured meat can also greatly increase the efficiency of food production (Credit: The Atlantic)

An interesting suggestion would be switch meat production from large vertebrate animals like cattle, sheep and pigs and replace it with raising of edible insects! You see a much larger proportion of an insect can actually be eaten than a cow or pig. They have no bones or tough hides; even the exoskeleton of some insects is nourishing. Also Insects are much less finicky about the sort of plant material they consume so they’re actually much more economical to produce per kilogram of edible food.

In many cultures eating insects is very common (Credit: How stuff works)

Now a new article entitled ‘Possibilities for Engineered Insect Tissue as a Food Source’ in the journal ‘Frontiers in Sustainable Food Systems’  (and yes this is the first time I’ve ever heard of that journal too!) suggests that the optimal food production strategy would be a combination of all of the possibilities I’ve mentioned above. Vertical farming would be employed to produce the cheapest plant material that would then be fed to genetically modified cultures of insect cells! Such a system, according to lead author Natalie Rubio of Tufts University, would provide the greatest production of food, again on a per kilogram basis, at the lowest cost not only in dollars but also in impact to the environment.

According to Doctor Rubio “Compared to cultured mammalian, avian and other vertebrate cells, insect cell cultures require fewer resources and less energy intensive environmental control as they have lower glucose requirements and can thrive in a wider range of temperature, pH, oxygen and osmolarity conditions.” (By the way osmolarity deals with the process of osmosis, the diffusion of chemical substances through a semi-permeable membrane, which is the way living cells absorb nutrients from their surroundings.)

Of course the big problem with manufacturing insect meat for food is that most people don’t want to eat insects, they’re icky! However that’s the beauty of cultured meat, the product doesn’t have to look like the animal the original muscle cells came from, it can look like whatever the customer likes.

Would you??? (Credit: Slate.com)

So what will insect meat taste like you ask? Well that’s the beauty of genetic modification; it could taste like whatever customers want! As a marketing campaign the name of the ‘product’ could be the Latin taxonomic name. For example Grasshopper meat could be sold as ‘Acrididae’ while ant meat could have a brand name of ‘Formicidae’. To the average shopper they’ll just be meat.

In time people will just get used to manufactured insect meat, especially if it’s cheaper than olde fashioned farm raised beef, pork or chicken. The organizations fighting animal cruelty will love it because no actual animals are really harmed. It sounds like a win-win situation all around.

So, you think that you’ll willing to try some?

Room Temperature Superconducting materials could revolutionize our technology in so many ways but will scientists ever be able to discover one? Also, the end of James Holzhauer’s streak as Jeopardy champion.

Everybody knows that there are some materials, primarily metals, which are able to conduct electricity. At the same time there are other materials like rubber or plastic that are insulators and through which electricity cannot flow. However even the best conductors, such as copper or silver still have a small resistance. Because of this nearly half of all of the electrical power we produce is just eaten up by the resistance in the kilometers of wire that are needed to get electricity from a power plant to your home or office.

Half of all the E;ectrical energy we generate is simply lost in the resistance of the wires needed to transmit it! (Credit: T&D World)

That some materials can become ‘superconductive’, loosing absolutely all of their resistance has been known since physicist Heike Onnes first discovered the phenomenon in 1911. The problem was that the materials Onnes studied only became superconductive at ultra cold temperatures, within just a few degrees of absolute zero (minus 273ºC). Because of the expense of the equipment needed to cool the conducting material down to the low temperatures needed to initiate superconductivity for many years the phenomenon remained a curiosity, of no practical value.

The potential uses of superconductivity are so great however that it’s not surprising that physicists kept looking, trying new materials in their search for a Room Temperature Superconductor (RTS). In fact there has been so much work carried out over the years that six Nobel Prizes have now been awarded for research into superconductivity starting with the one awarded to Onnes himself.

One breakthrough came in the 1980s with the discovery of ceramic conductors, technically known as cuprate-perovskite ceramics. These materials were found to become superconductive at temperatures higher than that of liquid nitrogen, minus 196ºC.

With that advance superconductive materials came into some limited technological use, primarily for the generation of powerful magnet fields such as those for Magnetic Resonance Imaging (MRI) scanners and magnetic levitation (Mag-Lev) in high-speed trains. These few uses of superconductivity have nevertheless become so economically valuable that they have increased the pace of research toward the discovery of superconducting materials that do not require any cooling at all.

Recently a new high temperature record has been set at the Argonne National Laboratory by a team of scientists from the University of Chicago. The new record is minus 23ºC, considerably higher than the temperature of ‘dry ice’ (solid Carbon Dioxide at minus 78.5ºC). A superconductor that only needs dry ice to cool it could greatly expand the industrial uses of the phenomenon.

Before you start buying stock in superconducting companies however I must tell you that the material, Lanthanum Hydride, formula LaH10 also requires a pressure of 270 Gigapascals or about 2 million atmospheres before it will exhibit superconductivity! In order to attain such a high pressure the tiny sample of material had to be squeezed between two diamond anvils.

X-Ray images of Lanthum Hydro have revealed the structure of the superconducting material (Credit: Drozdov et al)

If you’re thinking that 2 million atmospheres of pressure is a bigger technical problem than low temperature, well you have a point. However the researchers are hoping to find conditions under which the high pressure will initiate superconductivity but where superconductivity will remain once the pressure has been removed!

Whether the University of Chicago scientists succeed in their efforts or not the discovery of a material that is superconductive at temperatures that are commonly seen in the arctic regions of the World is still a major advance. With each step forward science learns a little bit more and perhaps one day soon superconductivity will become as familiar and widespread a property of our technology as semi-conductors are now.

 

Before I leave for today I would like to take a moment to mention the end of Jeopardy contestant James Holzhauer’s 32 game winning streak. Although Holzhauer only won about half as many games as the all time Jeopardy champ Ken Jennings did he still came within $60,000 of Jenning’s all time winnings of over $2.5 million!

James Holzhauer and his 32 game total Jeopardy winnings (Credit: Deadspin)

In other words Holzhauer’s per game winnings were about twice that of Jenning’s, which is what made James a very exciting player to watch. Whenever he got a ‘Daily Double’ he would often bet everything he had even if he already had a comfortable lead!

In the end Holzhauer was beaten by his own style of play. The new Jeopardy champion, Emma Boettcher was playing well but was still a bit behind Holzhauer when she got the last ‘Daily Double’. Following James’ example Boettcher bet everything she had and got the question right, taking a lead she never relinquished. To his credit James quickly congratulated Emma on her victory, indeed throughout his winning streak Holzhauer had often congratulated those opponents who had made him work for his wins!

Now of course Jeopardy is just a game show, but at least it’s a game show that requires more than a bit of knowledge and intelligence. I think TV could use more shows like Jeopardy that appeal to our intelligence so I’m glad that James Holzhauer’s reign as Jeopardy champion succeeded in increasing the show’s ratings quite a bit. Hopefully the success of James, and Ken Jennings and Emma Boettcher will inspire a few producers in Hollywood to create a few more shows like Jeopardy for those of us who like to think!

Hundreds of new Species from the time of the Dinosaurs are being discovered in Burmese amber, and why that may not be a good thing!

Ever since prehistoric times amber has been treasured as a rare and beautiful gemstone that we know was used in some of the earliest pieces of jewelry ever made. Amber isn’t actually a stone however; it’s just fossilized tree sap. That is, sap that has dripped down the side of a tree, dried out and become petrified over thousands or more likely millions of years.

Sometimes that tree sap can even capture a small living creature within it before it becomes hard, insects and spiders are the most common victims. And as the sap fossilizes the animal with it can be exquisitely preserved creating some of the best specimens of ancient life known to paleontology. This preservation in amber was even the main plot device in the ‘Jurassic Park’ movies where scientists obtain dino DNA from mosquitoes that have been preserved in amber.

In the Movie ‘Jurassic Park’ the top of Richard Attenborough’s staff was a piece of amber with a mosquito trapped in it (Credit: Daily Mail)

So it’s hardly surprising that paleontologists are always searching for new sources of amber that could contain unknown species from the past. In recent years the best, most interesting fossil amber has come from mines in the province of Kachin in the northeast of the country of Myanmar, formerly known as Burma. See map below.

I have already written a post about one of the most interesting finds discovered in Burmese amber, the tail of a very small dinosaur, with feathers on it. See my post of 16 December 2016 and the image below. Certainly the odds of something so rare happening must be enormous but given millions of years of past history even something that seems next to impossible will eventually occur.

The same could be said for a more recent find, the shell of an extinct sea creature known as an ammonite. See image below.

Ammonite shell (lower right) and a lot of other stuff found in Burmese amber (Credit: The Independent)

How could the shell of a creature of the ocean ever get trapped inside the sap from a land tree? Well one clue is that it is only the shell of the animal, all of the soft tissue had decayed before it was encased. Probably the shell was washed up on the shore, perhaps during a storm so that the waves could have could have pushed it fairly far inland, far enough to wind up at the base of a tree that was dripping sap. A one in a billion chance that; again if you wait long enough will happen.

Fossils in amber are also known from other sites around the world such as the Baltic or the Dominican Republic but the amber from Myanmar is both older and for some reason not yet understood, the sap occasionally seems to have trapped larger, stronger, more active creatures such as snakes, lizards and even a few birds. Because of these factors paleontologists are rushing to acquire as much of the Burmese amber as they can.

A few more interesting finds from Burmese amber (Credit: Science)

There is blood on the amber coming from Myanmar however, for the province of Kachin is a conflict zone and the amber mines are controlled by rebels who call themselves the Kachin Independence Army and who are fighting the central government. The situation in Myanmar is very similar to that of the blood-diamonds from Africa in the 1990s where militant insurgents would exploit natural resources in the regions they control in order to fund their rebel armies.

The mines from where Burmese amber comes are dangerous, low paying places to work (Credit: Science)

The same is now happening to the Burmese amber, which is smuggled into nearby China and sold in the markets of cities like Tengchong in Yunnan province. It’s there that paleontologists have to search in order to obtain the scientifically important specimens before they are sold to someone interested only in amber for jewelry.

In fact no paleontologist or geologist has ever been able to visit one of the amber mines in order to actually determine the precise age of the strata from which the amber comes. Present estimates of 99 million year old are based upon the study of the animals found in the amber and many scientists feel that the amber really has a range of dates.

Obviously this is not a good way to do science. A lot of information about the animal encased in the amber is lost when proper records are not kept. Paleontology is about more than just discovering and describing extinct lifeforms; it’s also about understanding the conditions in which they lived and with what other creatures. All that data is lost when a specimen is smuggled out of a war zone into another country and sold in an open market.

In the years to come I have no doubt that many more fascinating creatures from the age of the dinosaurs will be found in the Burmese amber. How much more could we learn however if scientists could obtain access to the source of the amber and do a proper job of excavation?

 

 

Space News for May 2019: Are we on our way back to the Moon?

Hopefully it’s not just because the 50th anniversary of the Apollo 11 Lunar landing is coming up in a few months but I’m certain that you’ve noticed there’s been a lot of talk about humans returning to the Moon recently. With that in mind I think I’ll use this month’s installment of Space news to offer my two cents worth.

Back in March NASA was officially tasked by the Trump administration with developing a plan for returning American astronauts to the Lunar surface by the year 2024, hardly enough time to prepare a robotic mission let alone a manned one. That detailed plan has now been released and the new Lunar program has a name at least, Artemis the Greek Goddess of the Moon and the twin sister of Apollo.

Now to be honest, this time NASA doesn’t have to start from scratch as they did back in the 1960s. With the Space Launch System (SLS) and the Orion crew vehicle the space agency has two of the three major components of an updated Apollo program almost ready to fly. Almost ready, as in both programs have encountered significant delays already and are several years behind schedule.

Still, the SLS and Orion are expected to undertake their first missions in 2020 so really all NASA needs to put astronauts back on the Moon is a new version of the Lunar Module (LM). You would think that if they concentrate their efforts on producing a LM five years should be enough time to develop one. In fact Lockheed Martin has already prepared some initial designs for just such a Lunar lander so there would be no need to start from scratch.

Problem is that NASA also wants to construct a space station in Lunar orbit called the Deep Space Gateway and building that could require several times the effort needed for just a new LM. The idea is for the Gateway to serve as a place to park a reusable LM module as well as conduct long-duration missions in deep space. See my post of 31Dec2018.

The complete Artemis program proposed by NASA is both boldly ambitious in scope and detailed in its planning. In addition to meeting Trump’s goal of a manned landing by 2024 the plan continues beyond that with one manned landing each year and concludes in 2028 with the establishment of a semi-permanent Lunar base. The total plan requires 37 launches in all, a mixture of SLS and Commercial Launch Vehicles (CLVs) like the Space X Falcon 9 or Falcon Heavy. Most of the missions will not in fact be manned but rather robotic spacecraft that will place equipment in either Lunar orbit or on the Moon’s surface.

The only thing missing now is of course the MONEY! While the full Artemis program should not cost as much as the Apollo program did, adjusting for inflation, it’s still going to require a major increase in NASA’s budget. All at a time when the Federal Government has virtually ground to a halt due to partisan bickering, a time when the yearly federal deficit is over a trillion dollars, and next year is an election year!

In order to get the ball-rolling Trump has promised to add another $1.6 Billion to NASA’s 2020 budget. That could pay for perhaps one of the 37 missions but hold on, he needs congressional approval even for that small increase.

A better sign of progress was NASA’s awarding of a contract to begin construction of the first of the Gateway modules to Maxar corporation. The $375 million dollar contract is for the design and development of the Power and Propulsion Element (PPE), obviously a critical section of the planned space station.

Still I have to admit that I don’t hold much hope for Artemis. In terms of an outline for an engineering project it’s first rate but there simply isn’t the political will in this country to get it done. We’ve been down this road before; George H. W. Bush directed NASA to go to Mars but never funded it. George W. Bush wanted to go back to the Moon but never funded it. Bill Clinton just wanted to build a Space Station but at least that got built.

Large-scale scientific project like manned exploration beyond Earth orbit require a long-term commitment by the politicians holding the purse strings. With our present political mess I see little hope of the kind of commitment needed any time soon!

What I’m most afraid of is that a year or so from now, when the hoopla and nostalgia of the 50th anniversary of Apollo 11 is past the current plans for a return to the Moon will all be forgotten and nothing will have been accomplished.

The Space Race part 6: The Saturn V rocket and Apollo 8

This is the sixth in a series of posts in celebration of the fiftieth anniversary of Apollo 11 and man’s first landing on the Moon. In this post I will discuss the design and development of the Saturn V launch vehicle, still the largest and most powerful rocket ever built. I will also talk about the Apollo 8 mission, the first manned mission to launch on the Saturn V and the first time astronauts left Earth orbit and traveled to another heavenly body, orbiting the Moon ten times before returning safely our planet.

The official NASA patch for the Apollo 8 Mission (Credit: NASA)

If anyone was going to get to the Moon by President Kennedy’s deadline they were going to need a big rocket, much bigger than anything that had ever been built before. Fortunately for NASA Werner von Braun, the German rocket expert that they had rescued at the end of World War II, had been thinking about a manned mission to the Moon since before Hitler’s rise to power. The image below shows von Braun with his circa 1955 concept of a Moon Rocket from a “Tommorowland” episode of “The Wonderful World of Disney”.

In late 1962 NASA settled that the mission profile for their Lunar program would be Lunar Orbit Rendezvous (LOR) wherein two spacecraft would enter lunar orbit, a mothership along with a smaller landing module that would carry two men to the Moon’s surface. Once the lander had returned the astronauts to lunar orbit it would dock with the mothership which would then bring the entire crew back to Earth.

With that profile settled von Braun could begin the design of the massive rocket that would be needed. Originally designated as the C-5 the Saturn V would dwarf all previous rockets consisting of three stages and standing more than 110m tall with the Apollo spacecraft on top.

Everything about the Saturn V was enormous; the thrust provided by its first stage was 33 million Newtons provided by five F-1 rocket engines for a total time of 168 seconds. The second stage’s thrust was lower at only 5 million Newtons but it burned for more than twice as long at 384 seconds.

The third S-IVB stage would fire twice, firing for a short time to nudge Apollo into Earth orbit while it’s second firing would propel the Apollo Command, Service and Lunar Modules to the Moon. In total the Saturn V was capable of lifting 140,000 kg into Low Earth Orbit (LOE) or 48,600 kg to an Earth Escape trajectory.

In late 1968 the Apollo Command and Service Modules (CSM) had already accomplished their first test mission in Earth orbit during the Apollo 7 mission and the Saturn V had completed its first unmanned launch on November 9th 1967. NASA’s schedule now called for a mission to test the Lunar Module (LM) in Earth orbit but the LM was behind schedule; it wouldn’t be ready until early in 1969. With only a year to go to meet Kennedy’s deadline the space agency had to make some progress.

It was NASA’s Apollo spacecraft manager George Low who suggested that Apollo 8 be assigned the mission of humanity’s first trip around the Moon. Such a mission Low argued, would provide a complete checkout of the full capabilities of the Apollo spacecraft and the Saturn V while at the same time testing NASA’s ability to track and communicate with Apollo all the way to the Moon and back. The fact that the CIA had information that the Soviets were preparing for just such a mission played no small role in the decision.

So it was that on December 21st of 1968 the Apollo 8 mission was launched from Cape Kennedy space center with a crew of Frank Borman, Jim Lovell and Bill Anders. The Saturn V rocket performed flawlessly placing the CSM, along with the S-IVB third stage into LOE. This combination of modules represented the first time that a manned spacecraft had been placed into space which was capable of leaving Earth’s gravitational field and journeying into deep space.

After spending two orbits checking out their spacecraft the Apollo 8 crew was given the command from mission control “Apollo 8, you are go for TLI” where TLI stood for Trans Lunar Insertion. The engine of the S-IVB stage was reignited and the crew of Apollo 8 became the first human beings to reach Earth escape velocity, they were on their way to the Moon.

During the sixty-eight hour journey to the Moon the CSM detached from the S-IVB stage, turned 180º about and ‘practiced’ removing a LM from its storage position place in the S-IVB. On the 24th of December, Christmas Eve, the spacecraft passed behind the Moon and the Apollo 8 crew became the first human beings to see the far side of the Moon with their own eyes.

Firing the Service Module engine while speeding over farside the Apollo spacecraft entered Lunar orbit, completing ten orbits in about twenty hours. With the Moon between them and Earth the Apollo 8 crew were completely out of radio contact, further from Earth than any human beings had ever been. As the CSM came out from behind the Moon the crew became the first humans to ever witness an Earthrise, see image below.

It was while orbiting the Moon on Christmas Eve that the Apollo 8 crew sent back to Earth a live television transmission that famously included a reading by the crew of the first chapter of the book of Genesis as translated in the King James Bible.

The riskiest stages of the mission were still to come. Would the Service Module’s engine fire again to speed Apollo 8 back to Earth and would the heat shied on the Command Module protect the crew as they reentered Earth’s atmosphere at the speed of 40,000 kph, over 11 kps!

The Apollo 8 crew and equipment performed flawlessly and the crew splashed down on December 27th 1968. Human beings had now journeyed to the Moon; all that remained was to land safely and return. Apollo 8 splashed down safely in the north Pacific Ocean on 27 December of 1968.

It’s Horseshoe Crab mating season in the Delaware Bay, a ritual of the natural World that’s nearly half a billion years old.

One of the most ancient forms of life on Earth are the Horseshoe Crabs, a family of arthropods that are actually more closely related to modern spiders and scorpions than real crabs. Horseshoe crabs have been living in the oceans of the world for more than 450 million years now, so long that they are commonly referred to as ‘living fossils’.

As befits their name Horseshoe Crabs have a hard external shell, the large front piece of which has a rough ‘horseshoe’ shape. Unlike the true crabs whose legs and claws come out of the sides of their shells however the legs of Horseshoe Crabs are underneath and completely covered by that hard shell.

Horseshoe Crabs are fairly common creatures; there are four species spread across the world. Here on the U.S. east coast the local species is known as Limulus polyphemus and they live in the shallow waters of the bays and inlets feeding off of small pieces of food, worms, small mollusks and whatever else they can find to eat in the sand.

The best time to observe Horseshoe Crabs is during their spring breeding season when they come ashore to mate and lay their eggs on sandy beaches. For me that means a trip down to the lower Delaware bay during late May or early June.

Now you have to find the right beach, too many people will disturb the crabs and the sandier the beach is the more crabs will come to mate on it. If you find the right beach at the right time however you get to watch as literally thousands of these ancient creatures come out of the water to create another generation of their kind.

Mating for Horseshoe Crabs is a pretty simple affair. The larger females come ashore and deposit their eggs into the sand. The smaller males grab the female from behind and fertilize the eggs as the female lays them. Competition amongst the males is fierce and it is not uncommon to find two or three males all trying to grab and mate with the same female.

For the best show you also have to come at the right time. The crabs come ashore at high tide but of course that’s when the beach is covered by water so they’re not easy to see. The best time to arrive is about an hour or two after high tide and then watch as the receding water reveals them by their thousands. I timed it perfectly this year as there were some Horseshoe Crabs already on the beach as we arrived but as the tide receded it seemed as if with every minute that passed more and more of the creatures appeared out of the water.

The annual mating of the Horseshoe Crabs is an important event for other creatures besides just the crabs. You see the crab’s eggs are very nutritious and represents a vital food source for several species of migrating shorebirds, especially the Red Knots.

Red Knots are a migratory bird with one of the longest yearly journeys of any living creature. During winter in the northern hemisphere the Red Knots live at the bottom of South America but they breed in the northern parts of Canada during the northern summer, a round trip of over 30,000 kilometers.

As you might guess the Red Knots need to find some good meals along the way. In fact the Horseshoe Crab eggs are so important to the birds that they time their migration so as to arrive along the U. S. east coast just as the Crabs are breeding. This interrelationship between two such different species is one of the more interesting stories that illustrate the complexity of life here on Earth.

Today both species, crab and bird are threatened by human activity. For a long time Horseshoe Crabs were cut up and used for bait in order to trap eels but they are also harvested for their blood that is used to detect bacterial infections by the pharmaceutical industry. (By the way, the blood of Horseshoe Crabs is based on copper rather than iron as ours is so it is blue in colour.) The biggest threat to Horseshoe Crabs however is the loss of breeding territory because of shoreline development.

The shell of this Horseshoe Crab has become the home of several barnacles. You can also see how the animal has been tagged to aid scientists in their studies of the creature (Credit: R. A. Lawler)

 

Watching the Horseshoe Crabs as they came ashore to lay their eggs I knew that I was witnessing one of the oldest annual events in the history of life here on Earth. As the shorebirds walked between the crabs feeding on the freshly laid eggs I began to wonder what creatures might have eaten those eggs say 350 million years ago. That would have been the time of the earliest amphibians, the ancestors of all modern vertebrates, reptiles, birds and mammals. Is it possible that the mating of Horseshoe Crabs might have provided food for our own distant forebears?

Horseshoe crabs are very ancient creatures after all, for all of our science we probably only know a fraction of all the things that they’ve seen.

Book Review: Survival by Ben Bova.

‘Survival’ is the fourth installment in a series of novels from six-time nebula award winning author Ben Bova. The series began with ‘New Earth’ where a human starship encounters a machine intelligence that calls itself ‘The Predecessors’. The machines inform the human crew that a ‘Death Wave’ of gamma radiation is spreading out from the supermassive black hole at the center of the galaxy that will destroy all life on the planets in our galactic neighborhood.

The Predecessors want to make a deal with humanity. They will give us the technology to survive the death wave if we agree to spread that technology to other intelligent species that are also threatened. In the second novel ‘Death Wave’ the crew returns to Earth and succeeds in convincing humanity to undertake this task, see my post of 31 May 2017.

The third novel ‘Apes and Angels’, see my post of 31Mar 2018, tells the story of one such expedition to save an intelligent, albeit primitive alien lifeform. In the latest installment ‘Survival’ the crew of the starship Intrepid undertake a 2,000 year long journey, the crew is in suspended animation, to a star system inhabited by another machine intelligence.

If you think about it, with this Death Wave idea Ben Bova has created for himself a fictional Universe that can support any number of novels. A human starship travels to a distant star, has whatever adventure Bova has thought of and so long as he can loosely connect it to the Death Wave concept it fits into the series.

The main plot in ‘Survival’ concerns the way the machines treat their human visitors. They don’t need the human’s help in surviving the Death Wave and the machines don’t really trust organic life to begin with. “Organic life is ephemeral,” the crew of the Intrepid is told several times, “Only machines are immortal.”

There are a couple of subplots in ‘Survival’ as well, one being the way that successful scientists often wind up becoming administrators who no longer have the time to do any research. The second is buried kind of deep but you catch it by the end, it’s the simple question of which is the better survival strategy, competition or cooperation?

If all of these concepts sound familiar to you maybe it’s because they’ve been storylines in science fiction for decades now, the old Star Trek TV shows did versions of all of them.

Indeed ‘Survival’ does have a Star Trek sort of feel about it, although without any of the action sequences. In fact there is little of anything that could be called action in ‘Survival’ and maybe that’s a good thing. Right now it seems as if SF novels are just full of violence, the last four novels I’ve reviewed all have a significant amount of murder and mayhem in them. (See my posts of 25Nov2018, Freefall; 12Dec2018 Planetfall; 13Feb2019, One Way and 3Apr2019, The Children of Time)

So an SF novel that succeeds, that makes you think without anybody getting killed is a nice breath of fresh air. It’s easy to use SF as just an excuse for a variant on a cowboy story with ray guns in place of six shooters and starships in place of wagon trains but the best Science Fiction is about thinking, not shooting!

Paleontology News for May 2019: Two new interesting species of dinosaurs discovered.

Most people know that the dinosaurs dominated Earth for over 150 million years but of course it wasn’t just one species of dinosaur and not all of the dinosaurs were so dominating. Some species were smaller, more inconspicuous relatives of the better-known giants while others represented evolutionary experiments that, for one reason or another simply did not leave any descendents, in other words they were experiments that failed.

I’ll start with the recent discovery of a relative of the famous Tyrannosaurus rex discovered in New Mexico by Dr. Sterling Nesbitt of Virginia Tech College of Science’s Department of Geosciences. Named Suskityrannus hazelae the two-legged theropod likely measured about 2.7 m from the tip of its nose to the end of its tail and stood less than a meter tall at the hip. This small meat eating would have weighted between 20 and 40 kg and likely hunted smaller animals.

According to Dr. Nesbitt, “Suskityrannus hazelae gives us a glimpse into the evolution of tyrannosaurs just before they take over the planet.” Based on the geologic strata in which it was discovered S hazelae lived some 92 million years ago near the beginning of the Cretaceous period. Because of the time it lived along with its anatomy S hazelae could prove to be a link between the older and smaller tyrannosauroids of North America and China and the much larger tyrannosaurids of which T rex is the best-known member.

The second new species of dinosaur to be discovered is rather a bit stranger. Ambopteryx longibrachium is a species of theropod dinosaur that flew, or perhaps only glided, with leathery bat like wings. Now I’m not talking about one of the pterosaurs, those bat like reptiles that lived at the same time as the dinosaurs but which weren’t dinosaurs.

A longibrachium is a theropod, the same group of dinosaurs that includes T-rex and from which the true flying dinosaurs, better known as birds, would come. In fact A longibrachium lived approximately at the same time as the first birds, the late Jurassic period some 163 million years ago, about the same time as the famous Archaeopteryx.

The fossils of A longibrachium are remarkably well preserved not only showing the membrane of their leathery wings but also the impressions of fuzzy feathers that were probably helped to keep the animal warm. The most critical part of the anatomy to be preserved was an enlarged, rod like wrist bone known as a styliform, an adaptation previously unknown in dinosaurs but present in pterosaurs and flying squirrels.

The fossil remains of A longibrachium were discovered in China by scientists at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences. Over the last few decades there has been a lot of paleontological research underway in China with important discoveries being made in many different periods of Earth’s history. (See my post of 10 April 2019)

So what happened to the dinosaurs like A longibrachium? Well perhaps the bat winged dinosaurs lost out to their relatives the evolving true birds. Or perhaps there was some ecological crisis that the bat winged dinosaurs failed to survive. We can’t say at present, but you can be certain that the paleontologists will keep searching for the answers, and isn’t that what science is all about!
