    Dragon 2 Propulsive Hover Test

    On November 24, SpaceX’s Dragon 2, powered by eight SuperDraco engines, executed a picture-perfect propulsive hover test at the company’s rocket development facility in McGregor, Texas.

    Eight SuperDraco thrusters, positioned around the perimeter of the vehicle in pairs called “jet packs”, fired up simultaneously to raise the Crew Dragon spacecraft for a five-second hover, generating approximately 33,000 lbs of thrust before returning the vehicle to its resting position. This test was the second of a two-part milestone under NASA’s Commercial Crew Program. The first test—a short firing of the engines intended to verify a healthy propulsion system—was completed November 22, and the longer burn two-days later demonstrated vehicle control while hovering.

    SES says SpaceX will launch its satellite in late February

    SpaceX’s next launch from Cape Canaveral is set for Feb. 24, when a Falcon 9 rocket will carry a commercial television broadcasting satellite aloft for Luxembourg-based SES, the payload’s owner announced Monday.

    The flight from SpaceX’s Complex 40 launch pad will be the first of more than a dozen missions the company plans from Cape Canaveral this year, and the second launch of an upgraded Falcon 9 rocket that debuted in December.

    The Falcon 9’s launch window Feb. 24 opens at 6:46 p.m. EST (2346 GMT).
    ...
    Because the Falcon 9 rocket will deploy SES 9 into a different orbit, the launcher will need to go higher and faster after liftoff.

    A SpaceX official said the company still plans to attempt to land the first stage after the SES 9 launch, but profile change means there will be a lower chance of recovering it. SpaceX has tried landing Falcon 9 first stage boosters on football field-sized ships three times, but the rocket has not survived intact.

    Fascinating.

    I watched the web feed of SpaceX sticking the landing in Florida. It was marvelous; it made me feel like when I was a kid watching the Apollo moon landings.

    Last time around they didn't stick the landing because of a part failure. Fingers crossed for success this time around. Reusable rockets will be a great stopgap measure until we agree on a proper non-rocket propulsion method and make it happen.

    Apparently, the reason this failed when I tried to watch it last time was because of a glitch with Firefox. The recent hvac-talk virus may have played a role.

    Scrubbed again.

    Launch aborted at T-1:40, near the end of oxygen loading.

    Launch will be rescheduled.


    Yesterday's launch was scrubbed because

    "Out of an abundance of caution, the team opted to hold launch for today to ensure liquid oxygen temperatures are as cold as possible in an effort to maximize performance of the vehicle."

    Who cares? How is all this a benefit to the U.S. and her people? I'm glad we went to the moon and it was a great goal and achievement. But now, why go back, why go up? We can't go to Mars because it's impossible take a vehicle powerful enough to escape her gravity. So who cares?

    It's impossible to escape earth's gravity or Mars?

    We've sent dozens of probes outside the reach of earths gravity. What are you talking about?

    I'm sure people like Marco Polo and Christopher Columbus heard the same arguments before they went on their voyages.. Even our space program gave us many benefits in terms of remote sensing and communications and it's still at the very early stages. In the future we will be able to get cheap raw materials, space manufacturing technologies (low gravity, vacuum), new computer/propulsion technologies and most importantly, more baskets for the egg representing the human race.
