SpaceX Successfully Launches Falcon 9 Rocket

leetrout writes "SpaceX has successfully launched a two-stage rocket, the Falcon 9, into Earth orbit from Cape Canaveral Air Force Station. 'Liftoff came after hours of delay, sparked initially by launchpad telemetry problems, then by a sailboat that strayed into a restricted area of the launch range. The day's first countdown was aborted at virtually the last second, due to a problem with the engine parameters, but the launch software was adjusted and a second countdown went all the way to the end.'" Update: 06/04 20:16 GMT by S : Reader mrcaseyj points out Spaceflight Now's coverage, which includes a number of pictures from the launch.

    What makes this one of the most important rocket launches in history is that, unlike at other rocket companies, the founder, Elon Musk, is determined to make a reusable rocket. The first stage of this rocket has been fitted with parachutes and covered with cork to protect it from the heat of reentry so that it can be recovered and studied in hopes of making them reusable in the future. The success of this launch solidifies the success of Spacex, and thereby dramaitcally increases the chances of huge benefits to humanity from much more affordable space launch. Also, the other rocket companies are probably very worried about losing all their business to Spacex now.

      Only the engine cluster is designed to be 'reusable' -it separates from the first stage fuel tank after booster separation. The cork material is thermal insulation for the cryogenic LOX used in the first stage.

      The cork is for protection during reentry. From the Spacex updates page:

      It is important to emphasize that the cork is not needed for ascent and there is no risk to flight even if it all came off. This is for thermal protection on reentry to allow for the possibility of recovery and reuse. While stage recovery is not a primary mission objective on this inaugural launch, it is part of our long-term plans, and we will attempt to recover the first stage on this initial Falcon 9 flight.

      Also on the Spacex updates page you can see the parachutes mounted in the interstage, implying that the entire first stage will be parachuted down. I would think the engine cluster would sink without the fuel tanks for buoyancy.

      Since 1957, you Space Nutters have had FIVE decades to show us these "benefits". Besides stoking the imagination of dreamers and deluded petulant children like GameboyRMH, there's precious little it has accomplished. Does it make clothes? Food? Materials?

      Look at that thing that's attached to your keyboard and mouse. The computer. The impetus for it's development was space. ICBMs can't fly in the atmosphere - they go into space. The little computers in your car that do everything from running the engine to your mp3 player? An offshoot. The ceramics that make the light turbines possible? Ditto. Better methods to monitor patients? Better ways to test materials? Better ways to model materials?

      The space race did three things

      1. it gave us a different "war" instead of fighting each other on the ground - a race in space.
      2. it gave us a different way to look at ourselves and our planet. That picture from the moon's surface makes it different. We're all in it together.
      3. it forced us to miniaturize, harden, and perfect computers and electronics for harsh environments. Your home computer gets the benefits. Transistors are now much cheaper than even staples.

      And this is all in addition to the benefit of now being able to say: Nuke it from orbit - it's the only way to be sure!

      ATK's Rockets that are used for shuttle launches are called "Reusable Solid Rocket Motors"

      Kind of an oxymoron there considering they are lost into the ocean and gone forever - reusable?

    I'm making a note here -- huge success!

    Hopefully this will reinvigorate the US market for launch vehicles. The satellite-manufacturing spin-off company of the research centre where I work currently launches most if not all of its payloads on decommissioned Russian ICBMs. I hope that in a couple of years, SpaceX's stable of launchers will be a practical and economical alternative!

  7. Impressive recovery by hcdejong · · Score: 4, Interesting

    Earlier today they had a launch abort at T -0:00:00. I happened to watch the webcast on the SpaceX site; the countdown got to zero and my impression was that ignition was underway when the launch was aborted.

    Had they used solid rockets, they'd have been SOL at this late stage.

    Also, finding the cause and then being able to launch inside 1.5 hours is rather quick. ISTR early Shuttle launches where the slightest setback resulted in putting the clock back to T -12h.

    And was the countdown off, or was the webcast not properly synchronized? I saw liftoff taking place at T -0:00:02.

    It's not the elimination of the NASA manned rocket program. It's about the descoping of the poorly conceived and poorly executed NASA manned rocket design and manufacturing program; whose significant purpose was employment in Alabama congressional districts. A private contractor will not decide on the mission goals or the payload. One can have robust manned space program without designing the rockets.

    In 1965 NASA had to design and build its own microcomputers. NASA does not do so any more; astronauts use standard laptop computers on the ISS.

    That's why Hitler and Stalin were so so gay for each other.

    I thought it was their mutual love of mustaches.

    Indeed. In fact, the real reason Hitler invaded the Soviet Union in 1941 was because he could no longer contain his jealousy over Stalin's thick luxurious mustache which was so much nicer than his own. If only Rogaine had been available millions of lives could have been saved.

    Put another way, when was Ares' first orbit?

    The article says SpaceX got $278 million from NASA to develop the rocket. Apparently we spent $1.500 billion on Ares in FY10 alone, and spent $445 million on a single sub-orbital test flight for Ares in '09.

    From Elon Musk's press telecon, as transcribed by flatoday.net:

    "We achieved a "near bulls-eye" on the orbit. There was a little more roll than was expected. It didn't affect the mission. It is something to be investigated and refined. We're very happy with the second stage performance."

    This isn't a spin-stabilized spacecraft, so I'd call what I saw more than just a "little roll"... still, damned impressive that the launcher can make an orbital bullseye while having that much uncontrolled spin.
