Secret American Spaceplane Returns to Earth

October 31, 2019

The Americans do have a secret space programme using the X-37B spaceplane. I very much doubt it involves anything as exotic as contact with extraterrestrials or uses back engineered alien technology. However, while the Americans have admitted the existence of the craft, they won’t reveal just what it’s doing up in the Deep Black. Yesterday, 30th October 2019, the I reported that the plane had returned to Earth after a record-breaking mission. The article by Marcia Dunn, ‘Secret space plane finishes 780-day mission’, ran

The US Air Force’s mystery space plane is back on Earth, following a record-breaking two-year mission.

The X-37B landed at Nasa’s Kennedy Space Center in Florida early on Sunday. The craft looks like a space shuttle – but is a quarter of the size, at just 29ft (8.8m) long.

The US Air Force is quiet about what the plane did after launching aboard a SpaceX rocket in 2017. The 780-day mission sets a new record for the reusable test vehicle.

Tight-lipped officials will say only that the mission successfully completed its objectives and that experiments from the Air Force Research Laboratory were aboard. It was the fifth spaceflight by a vehicle of this kind.

Barbara Barrett, the US Air Force Secretary, said: “Each mission advances our nation’s space capabilities.

Although the exact nature of X-37B missions are classified, air force officials have dropped hints about the type of experiments.

One was the launch of an advanced structurally embedded thermal spreader, an experiment designed to “test experimental electronics and oscillating heat pipe technologies”, according to an air force statement.

The plane flew to a higher orbit than previous X-37B flights, suggesting it had new experiments or technology tests. Air force officials said it carried multiple experiments and smaller satellites into orbit.

My guess is that some of those are almost certainly spy satellites.

A few years ago the X-37B docked at the International Space Station, but the US wouldn’t say what it was doing up there either.

Head of Asgardia Space Nation Attacks Trump’s Attempt to Set Up Space Force as Threat to Peace

October 25, 2019

One of the other stories that caught my eye last week was an article by Michael Day in the I reporting that the head of the international space nation, Asgardia, Igor Ashurbeyli, had attacked Trump’s decision to set up a military space force. Asgardia is an international organisation devoted to space colonisation. It’s intent on establishing itself as a new, internationally recognised nation out there on the High Frontier. The article in the edition for Wednesday, 16th October 2019, entitled ‘New US Space Command ‘puts the planet at risk”, runs

The billionaire head of the Asgardia “space nation” said that US President Donald Trump has effectively declared war on the 1967 Out Space Treaty, and risks creating a “Wild West” beyond Earth’s orbit.

The international agreement, banning weapons in space, was supposed to form the basis of law to guarantee peace beyond Earth’s orbit. But Igor Raufovich Ashurbeyli, told I that, in announcing a new Pentagon Space Command unit, Mr Trump has effectively torn it up – and put the planet at risk. 

“After the recent US statement that it will not respect international agreements in space, the situation is very worrying,” said Mr Ashurbeyli, the former head of a Russian state-owned defence contractor.

“In fact, the situation is worse than this, given that only 20 states on Earth have any sort of access to our space.”

Ram Jakhu, professor at the Institute of Air and Space Law, at McGill University in Canada, said the “increasing militarisation and weaponisation” in space appeared to be a prelude to serious conflict between superpowers.

“Currently, an intense race to the Moon and asteroids is going on, mainly for exploration and natural resources,” he added.

“There’s potential for geopolitical conflicts.”

Now Ashurbeyli, as the former head of a Russian arms firm, does have an interest, if only psychological, in preventing America establishing a military presence in space. But he’s right. The current treaty outlawing the militarisation of space was put in place partly to prevent the superpowers conducting nuclear tests in the Earth’s atmosphere or outer space. Tests which obviously have the potential for triggering a nuclear holocaust. The legislation has had the effect of preventing certain aspects of space research and new propulsion methods. The journey to Mars and other planets in the solar system could be cut down to a couple of months using nuclear powered rockets, but they’re illegal under the treaty. And while that’s a problem in the colonisation and commercial exploitation of space, I’m happy for it if it keeps the peace. If you want a Science Fictional illustration of the potential of the militarisation of space to create a nuclear war, see Kubrick and Clarke’s 2001. In the book and the film, the superpowers have established nuclear missile platforms in space, and the international situation between the two blocs is on the point of all-out war. The spacecraft you see gliding past before the camera fixes on the spaceplane Orion are these weapon platforms. However, it’s not obvious what they are because Kubrick didn’t want people seeing them and thinking that the movie was going to be another Cold War nuclear farce like Dr. Strangelove. In the book, but not the film, after Bowman’s journey through the stargate and his transformation into the Star Child, the crisis point has been reached and the superpowers launch their weapons. These are destroyed by the  Star Child when he re-enters Earth’s space. There is still the problem of the armed conflict, but the book concludes ‘He would think of something.’ Trump’s space command raises the spectre of such a conflict, but there would be no Star Child to save us from the resulting war.

It’s certainly possible that armed conflict could result through the competition by the space nations for the resources out there. The late NASA space scientist and advocate of space colonisation, Dr. Gerard O’Neill, believed that there could be real space pirates. These would be rogue ships seeking to steal the ores being brought back to Earth from mining the asteroids. I think we’re a few decades away from that, if not centuries, but the possibility is there nonetheless.

There have been a number of SF stories written about a possible war in space fought between the superpowers, including one by John Wyndham, the creator of the triffids. It’s certainly possible that war could break out through different nations establishing colonies on and claiming the same piece of extra-terrestrial real estate. There’s a parallel here to the wars the European nations fought against each other to claim territory in the New World. They attempted to prevent these wars coming home to Europe through an agreement that limited such conflicts to beyond the Line, the imaginary boundary marking off the Americas from the Old World. Conceivably, something like this could be put in place to stop wars on the Moon, Mars or elsewhere, from spreading to Earth itself. But I wouldn’t like to bet on any such treaty being agreed, or even being effective if it was.

I also remember the controversy and panic there was when I was at school during the New Cold War of the 1980s, when Thatcher and Reagan seemed to be spoiling for a fight with the USSR. One wretched element of this was Reagan’s Space Defence Initiative, dubbed ‘Star Wars’. Reagan wanted to place military satellites in orbit as part of its defence programme against the Soviet military threat. Such satellites would have weapons like ‘pop-up’ lasers. The satellites would carry nuclear bombs, which would explode, destroying the satellite. However, the energy from the explosion would be channelled into the lasers they also carried to destroy an incoming Soviet nuclear missiles. But the Russians were also afraid that these satellites would also strike at Earth itself. They had their own, official disarmament magazine, Gonka Vooruzhenie, which I think translates as ‘Disarmament People’. This carried illustrations of the threats to the Russian forces and people from Reagan’s space weapons. Trump’s Space Command threatens a repeat of this same episode from the Cold War. That ended with the USSR collapsing, partly because they couldn’t afford to keep up with American arms expenditure. We cannot depend on a similar outcome this time. 

Ashurbeyli is right. Trump’s decision to militarise the High Frontier threatens us all with nuclear Armageddon once again. 

Anton Petrov Shows Paintings of a Space Future that Never Came

October 19, 2019

And now for something a bit more cheerful. Anton Petrov is the Russian presenter of the YouTube show, ‘What Da Math’, about space and astronomy. The video below is the second part of his tribute to the Russian cosmonaut, Alexey Leonov, who passed away on October 11th, 2019. Leonov was the first man to make a spacewalk, but as his previous video also showed, he was also an artist. He worked with another artist, Andrei Sokolov, on the illustrations for a number of popular science books. Petrov’s earlier video showed some of them. This is a longer look at those paintings, which Petrov dedicates to those who dedicate their lives to inspiring humanity.

The paintings shown are truly beautiful. Yes, there are landscapes of the dull grey moons and the metal  of rockets and space stations against the black of space. But it’s also a universe of rich, deep colour – vibrant reds, yellows, blues and greens – the light of alien suns on the unearthly landscapes of distant worlds. They’re depictions of a future that never arrived, done when it seemed that Russia would win the space race and Communism would lead humanity to a more prosperous, technological future of international proletarian brotherhood. Progressive humanity would at last realise its destiny and conquer space, moving outward to space stations, the moon and then the rest of the Solar system and the stars beyond. It never happened. Communism collapsed, and the Soviets lost the space race. They had a record of spectacular firsts – first satellite, first man in space, first space walk, a series of successful probes to the planets and a solid record of prolonged life and research in orbit in the Salyut space stations. But they were beaten to the Moon by the Americans. The massive N1 rockets that would have taken them there kept blowing up until the programme was finally cancelled. Instead of sending a man, the Russians had to send instead an automated rover, the Lunakhod. In itself, this is no mean achievement, but it couldn’t match that of Armstrong, Aldrin and their successors. But these paintings look forward to that failed future.

However, it’s possible that something like the future they envisaged may yet come to be. Not created solely by the Russians, of course, but by all the other countries that are now entering space. Nations like India and China, as well as America, Britain and France, Germany and Switzerland with their designs for space shuttles. And if the Space Age really is going to arrive at last, it’s been a very long time coming. It’s fifty years since Neil Armstrong first walked on the Moon, and some of us would humanity to return for good. The Space Race always was somewhat artificial in that it was driven by largely political reasons, as both the Soviets and Americans tried to show which of their systems was superior by outperforming the other. But if the head of the Russian space programme, Sergei Korolyov had not died, but had lived to guide the design and construction of the N1, I think the situation might have been very different today. The N1 might have become a success, and the Russians just might have sent their own people to the Moon. They may not have beaten the Americans, but they would have come a very close second. And if that had happened, I don’t doubt that we’d have had a permanent base on the Moon. Just to make sure that the Soviets didn’t have all the place to themselves.

According to Petrov, the paintings themselves were taken from old postcards which are very difficult to get hold of. This is a pity, as these are paintings that would, I am sure, find an audience among western as well as Russian space fans and enthusiasts. There is a market for books and albums of SF and Fantasy art. Waterstones even has on its SF, Fantasy and Horror shelves collections of 100 postcards of Science Fiction book covers. Some of the published histories of SF, like John Clute’s Science Fiction: An Illustrated History – use illustrations from the novels, pulps and other magazines. There is thus space available, if I may use that phrase, for a similar volume of Russian and eastern European space art. Tarkovsky’s great Science Fiction films, Solaris and Stalker, are considered to be two of the classics of SF cinema. Similarly the Czech SF film, Ikarus IE was shown a couple of years ago at a British cinema. So why not a showcase of Russian and eastern European space art?

Petrov in his tribute was pessimistic about public interest in science, quoting a Russian film director, Kushantsev, who believed that there was no demand for popular science. In his opinion, people had regressed to the level of animals, wanting only to eat and sleep. I think this is too pessimistic. I can’t comment on Russia, but there certainly is a great interest in space and astronomy in Britain and America, as shown by the numerous series Brian Cox has churned out for the Beeb. Since the fall of Communism, western countries have filmed at Star City, the Russian centre of their space programme covering astronauts training for their missions to the International Space Station. Wannabe space tourists were offered the opportunity to train there themselves a few years ago, for the modest fee of £7,000. Russia is the country not just of the first man in space, Yuri Gagarin, but also Konstantin Tsiolkovsky, the deaf school teacher who investigated the problems of space travel and living in space in the 19th century. I therefore feel sure that there is an opening for a series on space fact, perhaps something like the British Sky At Night, on television presented from Russia, but perhaps with an international team.

In the meantime, however, we can admire these paintings. And I hope Anton Petrov, and other YouTube broadcasters on space and astronomy, like John Michael Godier and Isaac Arthur, will continue to educate and inspire new generations of humanity on their channels. 

Anton Petrov’s Tribute to Veteran Cosmonaut and Space Artist, Alexei Leonov

October 16, 2019

Last Friday, 11th October 2019, Alexei Leonov passed away, aged 85. Born on 30th May 1934, Leonov was one of the first Russian cosmonauts and the first man to walk in space. His obituary in yesterday’s I, written by Nataliya Vasilyeva, ran

Alexei Leonov, the legendary Soviet cosmonaut who became the first human to walk in space 54 years ago – and who nearly did not make it back into his space capsule – has died in Moscow aged 85.

Leonov, described by the Russian Space Agency as Cosmonaut No 11, was an icon both in his country as well as in the US. He was such a legend that the late science-fiction writer Arthur C. Clarke named a Soviet spaceship after him in his sequel to 2001: A Space Odyssey, the 1982 novel 2010: Odyssey Two.

Leonov staked his place in space history on 18 March 1965, when he became the first person to walk in space. Secured by a tether, he exited his Voskhod 2 space capsule. “I stepped into that void and I didn’t fall in,” he recalled later. “I was mesmerised by the stars. They were everywhere – up above, down below, to the left, to the right. I can still hear my breath and my heartbeat in that silence.”

Spacewalking always carries a high risk but Leonov’s pioneering venture was particularly nerve-racking, according to details that only became public decades later. His spacesuit had inflated so much in the vacuum of space that he could not get back into the spacecraft. He had to open a valve to release oxygen from his suit to be able to fit through the hatch. Leonov’s 12-minute spacewalk preceded the first American spacewalk, by Ed White, by less than three months.

Leonov was born in 1934 into a large peasant family in western Siberia. Like countless Soviet peasants, his father was arrested and shipped off to Gulag prison camps under Soviet dictator Joseph Stalin, but he managed to survive and reunite with his family. 

The future cosmonaut had a strong artistic bent and even thought about going to art school before he enrolled in a pilot training course and, later, an aviation college. Leonov did not give up sketching even in space, and took coloured pencils with him on the Apollo-Soyuz flight in 1975.

That mission was the first between the Soviet Union and the US, carried out at the height of the Cold War. Apollo-Soyuz 19 was a prelude to the international co-operation aboard the current international Space Station.

Nasa offered its sympathies to Leonov’s family, saying it was saddened by his death. “His venture into the vacuum of space began the history of extra-vehicular activity that makes today’s Space Station maintenance possible”, it said in a statement.

“One of the finest people I have ever known,” the Canadian retired astronaut Chris Hadfield wrote. “Alexei Arkhipovich Leonov, artist, leader, spacewalker and friend, I salute you.”

Russian space fans have been laying flowers at his monument on the memorial alley in Moscow that honours Russia’s cosmonauts. Leonov, who will be buried today at a military memorial cemetery outside the Russian capital, is survived by his wife, a daughter and two grandchildren. 

Anton Petrov put up his own personal tribute to the great cosmonaut on YouTube yesterday, 15th October 2019, at his vlog, What Da Math. Petrov posts about astronomy and space, and his video yesterday placed Leonov in his context as one of a series of great Soviet science popularisers before Neil deGrasse Tyson, Brian Greene or Carl Sagan. Petrov shows the stunning paintings done by Leonov with his friend, the science artist Andrei Sokolov. He describes how Leonov’s spacesuit expanded so that he couldn’t enter the capsule, and was forced to let some of the oxygen out. As a result, he nearly lost consciousness. This showed both the Russians and Americans that spacesuits had to be built differently. He also describes how Leonov, during his 12 minutes in space, was profoundly struck by the profound silence. It was so deep he could hear his heart pumping, the blood coursing through his veins, even the sound of his muscles moving over each other.

Petrov states that the Russian cosmonauts did not enjoy the same celebrity status as their American counterparts, who could live off book signings. Many had to support their families with other work. In Leonov’s case, it was painting. He illustrated a number of books, some with his friend Sokolov. These are paintings Petrov uses for the visuals in his video. He considers these books the equivalent to works by modern science educators like Carl Sagan. They were meant to encourage, inspire and educate. Sokolov’s and Leonov’s art was not just beautiful, but very accurate scientifically and included some SF elements. Some of these elements were borrowed by other science fiction writers. the opening shot of Stanley Kubrick’s 2001 is somewhat similar to one of Sokolov’s and Leonov’s paintings. This became a joke between the two, with Leonov creating a miniature version for the great American director to keep. Kubrick also borrowed many of the ideas for the movie from the Russian film director, Pavel Kushentsev. An extremely talented cameraman, Kushentsev made films about the first Moon landing, the first space station and the first man in space decades and years before they became reality. And all of his movies were scientifically accurate. Some of his movies are on YouTube, and Petrov gives the links at his site there for this video.

Petrov explains that he is talking about these men because their era has ended with Leonov’s death. Leonov was the last of the five astronauts on the Voskhod programme, and so all the men who inspired youngsters with amazing paintings and film are now gone. He considers it unfortunate that some of their experiences in the last days of their lives were not very happy. They did not live to see the future they depicted, and their paintings were not appreciated by the modern generation. Kushentsev said before his death,

Popular science is dying, because there is no money. No demand. Nobody wants to educate. Everyone just wants to make money everywhere possible. But one mustn’t live like this. This is how animals live. Men have reached the level of animals – all they want to do is eat and sleep. There is no understand that this humanity has passed a certain phase of evolution. We must understand the direction of this evolution. For this, we need culture, we need knowledge. 

Petrov believes Kushentsev’s criticism of modern Russian society also applies more broadly to the modern generation in the West, to all of us as well. We are all doing what he said we shouldn’t – just living for the money, to eat and sleep. Unfortunately, according to Petrov, nothing has changed in the 20 years since his death. But there are people out there in the world working to change this, to produce culture, to inspire and share knowledge. But sometimes the world crushes them, simply because it can. But Petrov says that, like those Soviet men before him, despite not being a famous astronaut or talented artist, or even someone who has very good diction, he will continue doing his part of sealing the hope for humanity, continue the work of these great men and inspire new generations to do things, believe in science and create a better world. Because as Leonov once said,

the Earth was small, light blue and so touchingly alone. Our home that must be defended like a holy relic. The Earth was absolutely round. I believe I never knew what the word ’round’ meant until I saw the Earth from space. 

Petrov concludes ‘Goodbye, comrade, and thank you for all the paintings.

This is the first of two videos about Russian art from that era of space exploration. I’ll post the other up shortly.

I don’t feel quite as pessimistic as Kushentsev. Brian Cox, who’s now taken Sagan’s place as the chief space broadcaster on British television, has attracted record audiences for his stage presentation about science and the universe. There is a massive interest among the public in space and space exploration. At the same time, there are a number of really great science vlogs and channels on YouTube. Petrov’s is one, but I also recommend John Michael Godier and the Science and Futurism channel, presented by Isaac Arthur.

Sokolov’s and Leonov’s paintings, they are of a universe of rich, vibrant colour. Spacesuited figures explores strange, new worlds, tending vast machines. They stand in front of planetary landers somewhat resembling the American lunar module. Or crawl across the landscape in rovers, gazing at horizons above which hang alien, often multiple, suns. The best space art shows worlds you’d like to visit, to see realised. These paintings have this effect. It’s a pity that on the blurb for this video over at YouTube, Petrov says that these paintings come from old postcards, which are difficult to come by. It’s a pity, as they still have the power to provoke wonder and inspire.

I’m not sure Leonov himself was quite so pessimistic. After the collapse of the Soviet Union, the main space museum was closed, and many of its exhibits sold off. Before it finally closed its doors to the public, they held a rave in it. I think Leonov was in attendance, sitting at the back with his wife. Someone asked him what he thought of it all. The old space traveler replied that they had found graffiti on the walls on Babylon complaining about the behaviour of the younger generation. ‘It is,’ he said, ‘the young man’s world’. It is indeed, and may cosmonauts, space pioneers, scientists and artists like Leonov, Sokolov, Kushentsev and Kubrick continue to inspire the young men and women of the future to take their strides in the High Frontier.

‘I’ Article on Planned British Lunar Rover

October 13, 2019

Friday’s I for the 11th October 2019 also had a really cool piece of space news. It seems that there are plans to send a British rover, designed by a start-up company, to the Moon in 2021. It is, however, tiny, and looks something like a four-legged, boxy mechanical spider. The article, ‘Give us a lift: Britain’s first lunar rover hitches a ride to the Moon’, by Nina Massey, runs

The UK’s first Moon rover will be sent into space in 2021 – and will be tiny.

Announced at the New Scientist Live event in London’s ExCel, British space start-up SpaceBit created and designed the robot. SpaceBit founder Pavlo Tanasyuk said: “Our goal is to go and see what is available there for all humanity to explore.”

He added that, unlike rovers with wheels or tracks, this robot with its four legs would provide an opportunity for “something a little bit like a human” to explore the lunar surface.

Only three other countries have put a rover on the Moon: the US, Russia and China.

In May, NASA announced that Astrobotic and two other companies had been awarded funding to build lunar landers.

US firm Astrobotic was awarded millions of dollars to carry up to 14 NASA instruments to the Moon, as well as 14 payloads from other partners.

SpaceBit will be one of those partners, sending the rover to the surface inside Astrobotic’s Peregrine lander.

It is expected to land in June or July 2021. Once the lander reaches the Moon, the 1.5kg rover will drop from beneath it to the surface along with other payloads.

It will scuttle across the surface taking measurements and collecting exploration data that can be analysed for scientific and exploration purposes.

It also has two cameras that will enable it to take “robot selfies”, SpaceBit said.

The reason for the legs is that in future lunar missions, the rover will go into lava tubes, which has not been possible before, Mr Tanasyuk said. he added: “It will spend up to 10 days on the Moon before going into the night and basically then freezing for ever.”

The article carried two photographs, one of the rover, and the other of Mr Tanasyuk holding a model of it.

This is great news, as it shows that British entrepreneurs are getting into space exploration. With luck, this rover should do better than the Beagle probe sent to Mars a few years ago. This was intended to find life, but crashed on its surface. SpaceBit join a number of other British space companies that have been set up, like Orbex, now building a spaceport in Scotland, and the expected development of the Skylon spaceplane. It seems that Britain may now be developing a full-fledged space industry, after the cancellation of the British space launcher project in 1975. I wish them God speed, and every success.

 

 

 

 

 

 

 

 

 

 

 

 

RAF Pilot Set to Join Branson Satellite Programme

October 6, 2019

There were a couple of really great, fascinating science stories in Friday’s I newspaper, which I’d like to cover before I get to the political stuff of attacking and refuting Boris Johnson, the Tories, and other right-wing nonsense.

One of these was the report that the RAF had selected a pilot to join the crews set to fly Cosmic Girl, an adapted 747 developed by Branson’s company, Virgin Orbit, send satellites into space. The article by Ewan Somerville, titled ‘RAF pilot gets space wings as first to join satellite programme’ on page 15 of the newspaper for Friday, 4th October 2019, ran

The Royal Air Force is heading for new heights after selecting its first pilot to join a space programme.

Flight Lieutenant Mathew Stannard has been assigned to a new £30m Ministry of Defence project. He will swap the cockpit of a Typhoon jet to fly a modified 747-400 plane, called Cosmic Girl, to launch satellites into orbit from mid-air, marking a “significant step” for British space endeavours.

A partnership between the RAF and space company Virgin Orbit to develop space technology, a response to billions of dollars being spent by the US, China and India, was unveiled at the Air Space Power conference in July.

Flt Lt Stannard hailed the programme a “truly unique opportunity” adding: “This programme is pushing the boundaries of our understanding of space so it’s a real privilege to be part of it and I’m looking forward to bring the skills and knowledge I gain back to the RAF.”

Over three years, Flt Lt Stannard will join several test pilots to send satellites into space from 30,000ft using a launcher attached to the Boeing 747’s fuselage. Freed from the need to launch from the ground, hi-tech satellites, developed by Britain, weighing only 300kg and described by Flt Lt Stannard as “the size of a washing machine”, could be launched from anywhere worldwide.

The RAF already has a similar small satellite, Carbonite 2, in orbit and plans for a “constellation” of them to provide HD imaging, video and secure communications. 

The mission is design to ensure Britain is not target by foreign powers for lacking its own space capabilities. It comes as the UK is due to send eight military personnel to join Operation Olympic Defender, a US-led coalition to deter “hostile acts in space” over the next 12 months.

I’m another British satellite launcher is being developed, even if the plane is made by Boeing, an American company. I’m also glad that the RAF have supplied an officer, as previous efforts to get a Brit into space have been hampered by squabbling within the armed forces. Before Helen Sharman became the first British person to go into space with the Russians to Mir, Britain was offered the opportunity by the Americans of sending an astronaut to go aboard the space shuttle. The army, air force and navy all put their men forward, and the scheme failed because of the wrangling over which one should be chosen.

I am not, however, altogether optimistic about this project as it’s a space company owned by Beardie Branson. How long has his company, Virgin Galactic, been claiming that ‘next year’ they’ll send the first tourists into space? Since the 1990s! I can see this one similarly stretching on for years. I have far more confidence in Orbex and their spaceship and launch complex now being built in Scotland.

As for using an aircraft as the first stage to send spacecraft into orbit, this was extensively discussed by the aircraft designers David Ashcroft and Patrick Collins in their book Your Spaceflight Manual: How You Could Be A Tourist in Space Within Twenty Years (London: Headline 1990). After discussing some of the classic spaceplane concepts of the past, like the XIB rocket plane and the Dynosoar, they also describe the design by the French aerospace company, Dassault, of 1964-7. This would have consisted of a supersonic jet capable of reaching Mach 4 as the first stage. The second stage would have been a rocket which would have flown at Mach 8, and used fuel from the first stage launcher. The whole vehicle was designed to be reusable.

The two authors also proposed their own designs for composite, two-stage spaceplanes, Spacecab and SpaceBus. These would have consisted of a jet-propelled first stage, which would piggy-back a much smaller rocket-driven orbiter. They estimated that Spacebus’ cost per flight would be higher than that of a 747, but much, much less than the space shuttle. It would be an estimated $250,000 against the Shuttle’s $300 million. Space bus was designed to carry 50 passengers, at a cost to each of $5,000. The pair also estimated that it would need $2bn to fund the development of a prototype Spacecab, and believed that the total development cost would be $10bn, the same as the similar Sanger concept then being developed in Germany. Although expensive, this would have been less than the $20bn set aside for the construction of the Freedom Space Station.

It’s a pity Ashcrofts and Collins’ spaceplane was not developed, though hardly unsurprising. Space research is very expensive, and the British government has traditionally been very reluctant to spend anything on space research since the cancellation of Black Arrow in 1975. The pair were also writing at the end of the 1980s, when there was little interest in the private development of spaceflight. This changed with the X-Prize in the 1990s so that we now have several private space companies, such as Elon Musk’s and Jeff Bezos’ outfits, competing to develop launchers, as well as Orbex. Hopefully, sooner or later, someone will start taking paying passengers into space and developing space industry. But somehow I doubt it’ll be Branson.

Crowdfunded Solar Sail Spacecraft Makes Successful Flight

August 6, 2019

Bit of science news now. Last Friday’s I for 2nd August 2019 reported that a satellite developed by the Planetary Society and funded through internet fundraising had successfully climbed to a higher orbit using a solar sail. This propels spacecraft using only the pressure of light, just like an ordinary sail uses the force given by the window to propel a ship on Earth, or drive a windmill.

The article on this by Joey Roulette on page 23 ran

A small crowdfunded satellite promoted by a TV host in the United States has been propelled into a higher orbit using only the force of sunlight.

The Lightsail 2 spacecraft, which is about the size of a loaf of bread, was launched into orbit in June. 

It then unfurled a tin foil-like solar sail designed to steer and push the spacecraft, using the momentum of tiny particles of light called photons emanating from the Sun – into a higher orbit. The satellite was developed by the California-based research and education group, the Planetary Society, who chief executive is the television personality popularly known as Bill Nye the Science Guy.

The technology could potentially lead to an inexhaustible source of space propulsion as a substitute for finite supplies of rocket fuels that most spacecraft rely on for in-flight manoeuvres.

“We are thrilled to declare mission success for Lightsail 2,” said its programme manager Bruce Betts.

Flight by light, or “sailing on sunbeams”, as Mr Nye called it, could best be used for missions carrying cargo in space.

The technology could also reduce the need for expensive, cumbersome rocket propellants.

“We strongly feel taht missions like Lightsail 2 will democratise space, enable more people send spacecraft to remarkable destinations in the solar system”, Mr Nye said.

This is very optimistic. The momentum given to a spacecraft by the Sun’s light is very small. But, like ion propulsion, it’s constant and so enormous speeds can be built up over time. It may be through solar sail craft that we may one day send probes to some of the extrasolar planets now being discovered by astronomers.

In the 1990s, American scientists designed a solar sail spacecraft, Star Wisp, which would take a 50 kg instrument package to Alpha Centauri. The star’s four light years away. The ship would, however, reach a speed of 1/3 that of light, meaning that, at a very rough calculation, it would reach its destination in 12 years. The journey time for a conventional spacecraft propelled by liquid oxygen and hydrogen is tens of thousands of years.

Although the idea has been around since the 1970s, NASA attempt to launch a solar sail propelled satellite a few years ago failed. If we are ever to reach the stars, it will be through spacecraft and other highly advanced unconventional spacecraft, like interstellar ramjets. So I therefore applaud Nye and the Planetary Society on their great success.

Amazon’s Jeff Bezos Plans to Take Us Back to the Moon

May 12, 2019

One of the other interesting pieces in yesterday’s I for 11th May 2019 was David Parsley’s article, ‘Amazon tycoons furthest delivery – putting people back on the Moon’. As the headline says, this is about the plans by Amazon’s Jeff Bezos for a crewed mission to the Moon within the next five years. The article runs

The man who made billions from sending parcels around Earth is taking one giant leap towards the Moon.

The world’s richest man and Amazon founder Jeff Bezos aims to send astronauts back to the Moon by 2024, 55 years after Neil Armstrong took his first small step.

Mr Bezos said his space company Blue Origin will initially land an unmanned robotic ship about the size of a small house, but would also help Nasa to meet its target to put humans back on the surface of Earth’s satellite in five years’ time.

“We can help meet that timeline but only because we started three years ago,” said Mr Bezos. “It’s time to back to the Moon, this time to stay.”

Known as Blue Moon, the reusable lunar lander is capable of carrying four rovers and uses a newly designed rocket engine powerful enough to carry up to 6.5 metric tons of cargo on the 238,000-mile journey.

Mr Bezos, who is worth £100bn, unveiled a model of one of Blue Moon’s proposed rovers, which was roughly the size of a golf cart, and presented a new rocket engine called BD-7 which can blast 10,000 lb of thrust.

“We have been given a gift – this nearby body called the Moon,” Mr Bezos added.

In March, US Vice President Mike Pence called on Nasa to build a space platform in lunar orbit and put American astronauts on the Moon’s south pole by 2024 “by any means necessary”, four years earlier than planned.

Blue Origin said the group would “share our vision of going to space to benefit Earth”. Based in Kent, Washington, the group is also developing the New Shepherd rocket for short space tourism trips and a heavy-lift launch rocket called New Glenn for commercial satellite launches. It is aiming to deliver the New Glenn rocket by 2021, while launching humans in a suborbital flight later this year aboard New Shepherd.

Elon Musk also develops plans to take humans to Mars with his company SpaceX. He previously set the first cargo-carrying Mars mission for 2022 and a crewed mission for 2024.

Meanwhile, Sir Richard Branson achieved Virgin Galactic’s first manned flight last year and plans to launch the first space tourism flights later this year. (p. 13).

This is very exciting, and I’m really looking forward to Bezos to take humanity back to the Moon, and Musk to send us to Mars. But I’m not going to hold my breath waiting for Branson to take tourists into space, as he’s been promising that ‘soon’ or ‘next year’ for decades.

However, I’d like Bezos to pay his Amazon workers a living wage first. From what I gather, the peeps working at his warehouses really are paid starvation wages. Which, I ‘spose, is how he get to be worth £100 billion. But he can afford to earn a little less, and workers a lot more. Sending people into space does not mean ignoring or exploiting the folks back on Earth. If he gives his workers a proper wage, then I’ll be behind him and his plans to take humanity to the planets 100 per cent.

‘I’ Newspaper: Scots Spaceport Company Has Rocket Ready for Launch in 2021

February 8, 2019

Excellent space news, if today’s I for 8th February 2019 is to be believed. According to the paper, Orbex, the company that’s building a spaceport to launch satellites in the Scottish highlands, has a rocket and intend making its first launch in 2021. The article by Lucinda Cameron, entitled ‘Rocket Revealed for Scottish Spaceport’ on page 13, runs

A spaceflight company has unveiled a new rocket as it opened its headquarters and rocket design facility in the Highlands.

Orbex, which is involved in plans to create a spaceport in Sutherland, said its new base in Forres, Moray, will create more than 130 jobs.

At the opening yesterday the company unveiled its Prime rocket, which is designed to deliver small satellites into Earth’s orbit.

Made from a specially formulated lightweight carbon fibre and aluminium composite, it includes what the company said is the world’s largest 3D printed rocket engine.

It is designed to work with biopropane, a clean-burning, renewable fuel source that cuts carbon emissions.

The Prime rocket will make its maiden flight from Scotland in 2021, when it will carry an experimental payload from UK-based Surrey Satellite Technology Lt, which manufactures small satellites.

Graham Turnock, chief executive of the UK Space Agency, said the new rocket design facility “firmly positions the UK as Europe’s frontrunner for those looking to Earth’s orbit and beyond for new opportunities.”

If all goes ahead as planned, then this is brilliant! Brilliant! As we used to say when I was at school. Britain developed a number of superb space rockets over the years, including the sounding rocket Skua used in high atmosphere research. The first and last time this country launched a satellite into orbit using a domestically developed rocket, it was way back in 1973 with Black Arrow. This was launched from Woomera in Australia, and carried the satellite, Prospero. After that, the politicians and civil servants decided that producing and developing rockets for space research was too expensive, and cancelled the programme. It was decided that instead we’d use American rockets. Which put us at a disadvantage, as it meant that we were dependent on the Americans and whether they had space available in their launch vehicles. Meanwhile, the French pressed ahead with their rocket development programme, and produced the superb Ariane, which is the launcher used by ESA, the European Space Agency, from its launch site in Kourou in South America.

After 46 years, Britain could once again be sending home-produced spacecraft back into the High Frontier.

Radio Programme on Controversy over Space Launch Site in Scotland

January 22, 2019

Radio 4 this Thursday, 24th January 2019, is broadcasting an edition of their Open Country programme on local attitudes and debate over the proposal to build a space launch complex in Scotland. The programme is entitled ‘Journey into Space, in Sutherland’, and the blurb for it in this week’s Radio Times runs

The A’Mhoine Peninsula in the Scottish Highlands has been chosen as the potential site of a spaceport that would launch small satellites at the rate of three a month. Many local people are enthusiastic about the plans; others are angry about building on a wilderness virtually unchanged since the last Ice Age. Ian Marchant travels to the peninsula and hears from people on both sides of the debate. (p. 137).

The programme is going to be broadcast at 3.00 pm in the afternoon, and will be repeated next Saturday at 6.07 am.
