They did it! Falcon 9 first stage on ship - now twice!
The Dragon is in orbit and the first stage is standing on the drone ship, just a little to one side of the center of the landing circle. Amazing stuff!
The video of the webcast right at the first stage landing: https://youtu.be/7pUAydjne5M?t=35m47s |

The drone ship was visibly pitching up and down in that video. I hope the landed first stage doesn't tip over due to the pitching and/or the wind before they can secure it, although I imagine they've calculated all of those load factors (and the stage probably has a low center of gravity, with its heavy Merlin engines and their thrust structure at the bottom). Also: The stage was significantly off-vertical even as it was quite close to touchdown, as the photo here shows (this page also contains another landing video link, see: http://spaceflightnow.com/2016/04/0...-status-center/ ), and SpaceX's website www.spacex.com has a full launch and first stage landing video for this CRS-8 mission up now. Below are links to the other "space...com" (including space.com itself, of course :-) ) websites' reports on this much-anticipated historic event: http://spaceflightnow.com/2016/04/0...for-first-time/ http://www.space.com/32517-spacex-s...gon-launch.html http://www.spacedaily.com/reports/S...ti me_999.html |

Posted on that other forum - a view of the landing from on board the Falcon 9(!) https://www.instagram.com/p/BD9d-HEF8SD/

Looks like it landed close to centre but then slid across the deck a bit, maybe because of the heavy seas.

That onboard video shows the "upper left" grid fin putting in a pretty large control input quite late during the descent, and in the external view of the final approach (see SpaceX's www.spacex.com video, to which kapton posted a link for the larger YouTube version in Reply #3 above), the stage can be seen changing its attitude, as well as translating horizontally, by significant amounts at very low altitude. Those movements of the first stage as it approached the ASDS, and the landing smoke blowing away quickly to the left (in the external view of the landing), appear to be consistent with the stage's apparent slight shift across the ASDS' deck right as--or *very* shortly before--the footpads contacted the deck surface (although wave action on the ASDS could have been the cause, or a contributing factor [along with the wind acting on the stage itself]). In addition: I'm sure that SpaceX will analyze the videos and vehicle telemetry in order to try for "on the X" (or at least closer-to-center) ASDS *and* land pad touchdowns in the future, because the ASDS deck space doesn't allow very much room for error (their land pads aren't as constrained regarding allowable "center miss radii"). |
That's the future, boys...
NASA is starting to look like they're standing still. Later! OL J R :) |
Nope, NASA is just too busy trying to determine if there is climate change affecting Greenland by putting more jet exhaust in the air.
OMG NASA OMG |
Guys,
Does anybody know where I might find info on how far down-range the Drone ship was? I think these launches head Northeast |
