TECHNOLOGY - SpaceX, another first

It was a privilege to be able to watch SpaceX's live webcast of the launch of their first Dragon capsule. This is a unique achievement, it's the first time a private company has put a spacecraft into orbit and safely returned it to earth.

Launch of Falcon 9 and Dragon, 8th December 2010The icing on the cake is that they also manoevered Dragon while in orbit, testing some of the moves that will be required to dock with the International Space Station (ISS). But why is all this such a great thing?

Let me explain. The human race undoubtedly has a built-in urge to explore and try out new things. We might have different views on the reason for this, and some might argue that space exploration is far too expensive to justify. But for whatever reason people have a built-in desire to explore beyond the boundaries, to go further than before, to see and understand new things.

SpaceX have done something amazing. They are a small company working on a small budget, in just eight years they have developed two launcher families and a spacecraft and have won a NASA COTS contract to resupply the ISS and return cargo to Earth. In the past only nations and groups of nations have returned a spacecraft from orbit. The Soviet Union and the United States achieved this in the early 1960s, and later China, Japan, India, and the European Space Agency (ESA) have done so too.

SpaceX was founded and is managed by Elon Musk, reinvesting some of his personal fortune earned by creating PayPal. Elon and SpaceX are determined to reduce the cost and increase the reliability of spaceflight tenfold and they have now demonstrated a realistic chance of doing so. Not only did they fly Dragon to orbit and return it intact, the spacecraft and (potentially) the first stage of Falcon 9 are reusable for multiple flights.

They have built all the hardware themselves, including the rocket engines. The designs are deliberately simple and the propulsion systems are modular and include a great deal of built-in redundancy.

Finally, Dragon and Falcon 9 were both designed with a view to launching crews to low Earth orbit. This is expected to take a further two to three years and Dragon will accomodate up to seven astronauts.

SpaceX deserve a huge round of applause for an outstanding achievement. As a recent aerospace start-up company what they have done is truly game-changing.
