    How does Falcon Heavy stack up against Delta IV Heavy, SLS(BLK !) and Saturn V.

    https://mashable.com/2018/02/02/spac...1#roas5Pwrwkqf

    After years of delays and setbacks, SpaceX is finally ready to launch the maiden flight of its Falcon Heavy rocket, which is scheduled for Feb. 6.

    SpaceX has said that the launcher, with its 27 engines and 3 boosters, will be the most powerful rocket currently flying when it makes its debut on Tuesday.

    But how does that really stack up?

    License to launch Falcon Heavy obtained by SpaceX on February 2nd.

    http://spacenews.com/spacex-receives...-heavy-launch/

    The Federal Aviation Administration has issued a launch license for the inaugural launch of SpaceX’s Falcon Heavy, scheduled for Feb. 6.

    The license by the FAA’s Office of Commercial Space Transportation, or AST, is dated Feb. 2 and covers only the first launch of the Falcon Heavy, the largest U.S. launch vehicle since the Saturn 5. A license is required for any commercial launch from the United States or by a U.S. company regardless of location.

    The license describes the rocket’s payload as a “modified Tesla Roadster (mass simulator)” that will be launched into a hyperbolic orbit with respect to the Earth. SpaceX Chief Executive Elon Musk said in December that the Roadster, an electric sports car, would be the payload, launched into a heliocentric orbit that will take it past Mars. The license does not describe the modifications to the car.

    The license was the final regulatory hurdle to the upcoming launch. While there were no significant doubts that the company would obtain a license, the unusual nature of this launch, featuring the first launch of a vehicle and its nontraditional payload, likely attracted additional scrutiny.

    I'm guessing that before launching the car you'd want to remove the batteries, which might be hazardous in case of failure, then add a space-rated battery for playing the music.

    Any idea of what time?

    At the very least, the world record "pearls before swine" has been broken: the average newspaper has an article with little detail about the FH test launch. The average reader has no clue about the (not mentioned in said articles) concepts of mass simulators and test flights, the unique aspect of reusing first stages versus dropping them in the ocean, economics, etc. Result: the vast majority of online newspaper reactions is along the lines of "doesn't know what to do with his money", "polluting space", "so much for eco friendly*", "feed the children"...

    (*)an argument about the ecological aspect of current electric cars could be made, but I'm afraid not by those people...

    From the NY Times

    SpaceX will broadcast the launch on its website, spacex.com, beginning at 1:10 p.m. Eastern, and on YouTube. We’ll add the live video feed to this page once it becomes available.

    The launch window is from 1:30 p.m. to 4:00 p.m. Eastern. Weather forecasts call for an 80 percent chance of favorable conditions. If the weather doesn’t cooperate, or if some technical glitch postpones the launch, SpaceX has a second opportunity on Wednesday, also between 1:30 and 4:00 p.m.

    Wind shear appears to have delayed the launch. That's a bit of a blow.

    They're still showing just under an hour from now on Twitter, so less than an hour's delay so far.

    Of course I have a teleconference with a customer at 3. I'm sure they'd understand if we canceled it.... not.

    Yes, 3:45 p.m., Eastern Standard Time. (20:45 GMT, 12:45 p.m. Pacific Time). That's crowding up against the end of today's launch window, which closes at 4:00 p.m. EST. Excessive wind shear at high altitudes is given as the cause of the delay.

    From the press-kit :
    SpaceX will attempt to land all three of Falcon Heavy’s first stage cores during this test.
    This should amaze me more, but it's almost becoming standard already. Wow, Musk...

    Formation flying of rocket boosters is standard to you? How jaded are today's youth?

    That's going to gnaw at me if you don't tell me where that's from.

    I was just thinking about this (landing all three boosters). They already know how to do it, and I think the booster largely does it autonomously. If they get them aloft and the outer ones successfully separated, landing seems pretty likely.

    The webcast is now playing spacey music.

    SUCCESS!

    Somehow I missed the first 2 minutes, so I'm awaiting a replay of the launch itself. I saw the 2 boosters land simultaneously. Status of the core on the ship is unclear atm. Tesla is out of its shroud, still needs to detach though.

    Any word regarding the center core?

    And yes, that was amazing!

    Watching the two side boosters land at the same time, side-by-side, all I could think was "Oh, now you're just showing off".

    Thanks for the replay link. Any news on the barge yet? Tesla separation?

    We were reaching booster sync levels that shouldn't even be possible. Most impressive!
