TECHNOLOGY - Dragon readies for launch

Most people are aware that the American Space Shuttle fleet is being retired. The last flight is currently scheduled for next year, 2011. After that, the only way Americans will be able to travel to orbit and dock at the International Space Station (ISS) will be to buy seats from the Russians.

SpaceX's Dragon capsuleThe Constellation Program that was intended to replace the Shuttle has been cut and modified several times and is unlikely to provide a crewed launch facility soon or, perhaps, ever. China has a crewed vehicle, and Europe and Japan both have operational cargo craft from which crewed vehicles might be developed. India is planning and building a crewed launch system.

What the USA does have however is something quite unique. It has several businesses designing and building crewed spacecraft as commercial ventures.

One of these is SpaceX, based in California. They launched the first of their Falcon 9 rockets carrying a dummy Dragon capsule in June 2010. In November they plan to launch another Falcon 9 with a fully functioning Dragon cargo capsule to test the re-entry and landing systems. If all goes well, next year they will be in a position to begin carrying and returning cargo for the ISS - and they already have a full order book from NASA and other clients around the world.

Dragon was designed from the ground up to be capable of carrying seven astronauts in place of cargo. SpaceX is hoping that once Dragon is proven as a reliable cargo system NASA will decide to fund its upgrade and testing as a crewed vehicle.

I wish SpaceX well and hope the mission in November will be a complete success.
