TECHNOLOGY - Reusable rockets

SpaceX is an innovative space launch company with a number of impressive 'firsts' to their name and a large order book of reservations for satellite launches on their Falcon 1 and Falcon 9 vehicles.

The planet MarsThe company was founded by Elon Musk using capital earned by his earlier IT businesses, particularly PayPal which was sold in 2002 for $1.5 billion. Musk's share was more than 10% enabling him to start SpaceX as well as the electric car company, Tesla.

In September 2008 Falcon 1 achieved earth orbit, the first time a privately owned company had orbited a liquid fuelled rocket. All previous successes were by the government programs of a variety of nations.

In June 2010 Falcon 9, a much larger vehicle, also flew successfully to orbit. And in December 2010 Falcon 9 flew again, this time carrying a Dragon capsule which completed two orbits, successfully re-entered, splashed down and was recovered. This was another first for a private company.



A heavy rocket is planned (Falcon 9 Heavy) and a demonstration flight to dock Dragon to the International Space Station (ISS) is due in 2012.

But now, SpaceX has announced plans for full reusability. If they can pull this off it will be an utter game-changer, reducing the cost to orbit by perhaps 100 times.

Elon's recent presentation to the US National Press Club explains the reason for the attempt to operate a reusable rocket. His long term goal is nothing less than to colonise Mars. This might sound crazy, but he has a track record of doing things that were thought to be impossible. So maybe he will succeed. If anyone can, Elon and SpaceX can!
