SpaceX Legs It Out

SpaceX founder Elon Musk tweeted last night the above image of a Falcon 9 with legs attached. This booster is in the SpaceX horizontal integration facility at the Cape's Launch Complex 40.

In two accompanying tweets, Musk wrote:

Mounting landing legs (~60 ft span) to Falcon 9 for next month's Space Station servicing flight.

However, F9 will continue to land in the ocean until we prove precision control from hypersonic thru subsonic regimes.

The landing legs are to help evolve the SpaceX Grasshopper technology which intends to steer first-stage (and eventually upper stage) vehicles to a landing pad so they can be refurbished and used again.

While that demonstration is years in the future, for now SpaceX may attempt to demonstrate they can return the first stage to a specific target in the Atlantic Ocean.

This Falcon 9 will be used for their next commercial cargo delivery to the International Space Station, scheduled to launch March 16. It's appropriate to use a NASA mission, because the agency's charter requires it to “contribute materially” to “the improvement of the usefulness, performance, speed, safety, and efficiency of aeronautical and space vehicles.”


  1. "While that demonstration is years in the future"

    Might not be so far away as that. Elon Musk has said it could happen by the end of this year if all goes well with the tests. Garrett Reisman of SpaceX confirmed this the other night at the SpaceUp Houston commercial spaceflight panel event:

  2. Thanks for sharing ... I wish the SpaceUp Houston event video was online somewhere so I can watch. I prefer to take the conservative road and give them some room for error. :-)
