The Boeing X-37, also called the Orbital Test Vehicle (OTV), is an unmanned American spacecraft. Its first orbital mission was on 22 April 2010 returning back to Earth on 3 December 2010. A second X-37 was launched on 5 March 2011 and has not yet returned to Earth at time of writing (23 April 2012) spending over a year in space. The United States Air Force (USAF) described the mission as classified and limited details have been released on why the craft was launched, what the payload is onboard and future uses of the craft. This has led to a lot of speculation on its “true mission”.
If you would like to read more into the beginnings of X-37 then please click here. But I will look at the conspiracy theories and future uses for the X-37.
The USAF revealed that the mission of the X-37 was to test new space technologies, but with few details released on the mission the conspiracy theorists have began to speculate. The main theory is that it has been sent up to spy on the Chinese. The China Space Program has really picked up momentum. They launched a spacelab called Tiangong-1 in September 2011 and expect to send a crew there this year. Of course the Americans are wary at the pace of developments especially as China plans to send another probe to the Moon within the next three years and send a manned lunar mission by 2020. This will significantly close the gap between the two superpowers. So, although the Chinese spacelab is unmanned at the moment, the theory is that the X-37 is spying on it.
It is true that it looks like the X-37 does share a similar path around the globe as the spacelab Tiangong-1 and it has been tracked from the ground by those intrigued by its purpose as being on the same route. But although similar in that they are both about 300km (180 miles) above Earth with roughly a 43 degree inclination, their orbit is vastly different by some 100 degrees, meaning that they intersect just twice per orbit. So, would it be correct to say that when the two vehicles pass each other the USA must be gaining very detailed results from their espionage? Wrong, when they pass each other it is at speeds up to 8000 meters per second so gaining any valuable data would be near impossible!
Another important point to note is the dates when Tiangong-1 was launched and when X-37 was sent into orbit. If X-37 was a spying mission then surely the launch of Tiangong-1 preceded it? No, X-37 was sent up in March 2011 with the Chinese Spacelab launched in September 2011. So if the Americans were sending their craft up to spy on a lab that was not yet in space, then it would have been a guessing game to decipher when Tiangong-1 would be launched and the orbit it would take! So is it a spying spacecraft?
In my opinion most likely it is not, if the USA wanted to listen in on Tiangong-1 they could do it probably without the effort of sending a craft into space, but everyone loves a conspiracy theory!
Another line of thought is that it has been sent up to tamper with enemy satellites as the X-37 has the capability to manoeuvre and change its orbit.
To me this sounds like something out of a James Bond movie and reminds me of one of the earlier Bond films starring Sean Connery, You only live Twice. In this film an American space craft is swallowed up by a mysterious enemy capsule in what can only be described as a “Spacejacking”. This almost starts all out nuclear war, well that is before 007 saves the day! Fact or fiction, some people still believe that the X-37 could serve as an orbital bombing machine and that the secret payload onboard is munitions!A scary thought which I hope is not true.
What interests me more is the capability of one day having a manned X-37 flight.
The X-37 is thirty feet in length and approximately nine feet high, so too small to have astronauts onboard. But, Boeing has plans to build an X-37C spacecraft which would be a 165% scale up on the one being utilised now. This could allow both cargo and passengers to orbit in space and even travel to the International Space Station. This could allow America to once again have their own space transport vehicle and not be reliant on the Russian Soyuz rocket as they are at the moment.
Perhaps the secrecy surrounding X-37 stems from the fact that commercial companies are developing spacecrafts that they hope can replace the shuttle. One such craft being developed by the company SpaceX is called the Dragon. So perhaps secrecy is the best policy to hid potential data that competitors could steal.
Another use for the X-37 would be as a transport vehicle for satellites that are facilitating experiments in orbit. The X-37 could bring the satellite up into orbit and once the experiment has been completed, recollect it and bring it back down for the results to be analysed and of course the satellite can be reused again.
So in conclusion, the X-37 is a bit of a mystery. It was designed to spend around nine months in orbit, but the second mission has endured over a year in space with no plans released for its return yet. We still don’t know what exactly the craft is doing up there and what the payload is. But, it has proven to be durable and reliable (the top brass seem pleased with it) which is great news for the Americans given the cutbacks in the space program by President Obama. Watch this space for further details on X-37, who knows one day it could be taking astronauts into space and could become the permanent replacement for the Space Shuttle. Or perhaps you think that it is indeed a vehicle used in some sort of espionage plot.
Either way I would love to hear your comments on it!
