Spacex shows the re ignition of the rocket engine over the ocean

RATE THIS! +81

 Spacex reviewed the September 29th, 2013 launch of the upgraded falcon rocket. They included a picture of the first stage re-igniting its ending just above the ocean. This was to demonstrate using the engines to slow down and land for reusable rockets.

 
Though not a primary mission objective, SpaceX was also able to initiate two engine relights on the first stage. For the first restart burn, we lit three engines to do a supersonic retro propulsion, which we believe may be the first attempt by any rocket stage. The first restart burn was completed well and enabled the stage to survive reentering the atmosphere in a controlled fashion.
 
SpaceX then lit the center engine for a single engine burn. That relight also went well, however we exceeded the roll control authority of the attitude control thrusters. This particular stage was not equipped with landing gear which could have helped stabilize the stage like fins would on an aircraft. The stage ended up spinning to a degree that was greater than we could control with the gas thrusters on board and ultimately we hit the water relatively hard. 
 
However, SpaceX recovered portions of the stage and now, along with the Grasshopper tests, we believe we have all the pieces to achieve a full recovery of the boost stage.

I have not seen this much activity going on in the space program for over 40 years, so I think this is just awesome. I would love to see them get to and colonize mars while I am still alive I think that would just be awesome.

Another launching, another success, wow SpaceX record is doing quite well I would say. The little problem they did have will be fixed in short order I am sure. Their work is awesome and I am proud to have them at the head of our space program. Reply
