Video on Proposed Swiss Space Shuttle

October 13, 2019

This is an interesting little video from Swissinfo on YouTube about Swiss Space Systems, a company set up by engineer Pascal Jaussi, which is developing another space shuttle concept. Jaussi was inspired to become a space scientist as a child after he was given a copy of the Tintin book, Tintin on the Moon. His company’s design for the shuttle will have it taken up to 10,000 metres by a passenger jet acting as the shuttle’s first stage. The shuttle will then leave the jet, flying up to a higher altitude, where it will launch a satellite, which will then ascend to its final orbit using its own rockets. The shuttle is initially intended to be a satellite launcher, but later missions will be crewed.

Jaussi’s company does not intend to develop any new technology, but is simply trying to use and integrate already existing technology from America, France and Russia. This is aided by Switzerland’s neutral status. The American’s would understandably be extremely reluctant to give sensitive technology to the Russian the firm, which is building the engines for Jaussi’s shuttle. They’re the same as those in the Russian Soyuz rocket. The French aerospace firm Dassault is responsible for constructing the shuttle’s airframe. The company’s based in Jaussi’s home town of Payerne, in Vaud canton. He would like to build the launch complex there with another, launch complex without an accompanying crew planned for Croatia. The video also shows the shuttle’s cameras being tested in Canada. The video was posted four years ago in 2014, and states that the first test flights were planned for 2018.

This is another version of the Jet/shuttle combination initially proposed by Sanger in Germany. I’ve already blogged about British shuttle proposals using the same idea, Spacebus and Spacecab, by David Ashcroft and Patrick Collins.  The Swiss design is interesting, but 2018 was last year and the fact that we haven’t heard anything more of this fascinating project suggests that it’s experiencing difficulties. I hope that these are just a minor setback, and that we can look forward to the Swiss joining the other nations now entering a new Space Age, one that will lead to the proper exploration, industrialisation and hopefully colonisation of the solar System.













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.
