All it takes is one good upswell and you get another hard landing. Link to comment Share on other sites More sharing options...

Unobscured Vision Posted January 17, 2016 Share Posted January 17, 2016 Yeah, I was thinking that independent suspension with shock absorption and gyros would be the next logical upgrade also. Those landings aren't exactly soft even in the best of circumstances. 12-foot seas make things nearly impossible to keep upright though, so yeah. Bad day to try a sea landing.

The Jason 3 satellite has been released from the upper stage of SpaceX's Falcon 9 rocket, beginning a five-year mission to measure the oceans from orbit. Jason 3's two solar panels will unfurl in a few minutes. Separation was into a 1320 x 1305 km orbit. http://spaceflightnow.com/2016/01/17/falcon-9-jason-3-mission-status-center/ Unobscured Vision 1 Share Link to comment Share on other sites More sharing options...

Draggendrop Veteran Posted January 17, 2016 Veteran Share Posted January 17, 2016 Final SpaceX Falcon 9 v1.1 successfully launches Jason-3 Quote While the second stage was making its first burn, the first stage performed manoeuvres of its own to facilitate its landing attempt. This was considered a purely experimental objective, with no bearing on the overall outcome of the launch. To facilitate recovery, the first stage restarted three times after separating from the rocket. The first of these was a boostback manoeuvre to change the stage’s trajectory and put it on course for the ASDS. This began about 100 seconds after stage separation; four minutes and 25 seconds after liftoff. The stage then made a burn at around the seven minute mark in the flight, to slow itself as it reenters the atmosphere, before finally restarting shortly before landing in order to slow its speed. The landing attempt was approximately eight and a half minutes after launch, although video from the ASDS was lost prior to confirmation it was unsuccessful. mission data at the link... http://www.nasaspaceflight.com/2016/01/spacex-launch-jason-3/ Quote 14:57 Pyros fired to begin deployment of the two solar array panels, but confirmation of a good deployment and a power positive state on the Jason 3 spacecraft will come in about 20 minutes when the satellite passes over a ground station in Fairbanks, Alaska, NASA says. http://spaceflightnow.com/2016/01/17/falcon-9-jason-3-mission-status-center/ Unobscured Vision 1 Share Link to comment Share on other sites More sharing options...
DocM Posted January 17, 2016 Author Share Posted January 17, 2016 @elonmusk Definitely harder to land on a ship. Similar to an aircraft carrier vs land: much smaller target area, that's also translating & rotating.

DocM Posted January 17, 2016 Author Share Posted January 17, 2016 One item re: the leg failing @elonmusk However, that was not what prevented it being good. Touchdown speed was ok, but a leg lockout didn't latch, so it tipped over after landing. Due to this being an older NASA contract the launcher version and configuration was frozen as an F9 v1.1. As such, they couldn't use the F9 FT which has the revised and high strength legs. An F9 FT may well have pulled it off.

PaulRocket Posted January 17, 2016 Share Posted January 17, 2016 So this is actually really good news! Despite the rough sea state the stage had the right velocity and Elon seems to imply that ASDS movement were no problem, but rather that one leg!
