Frida Space Posted February 11, 2015 Share Posted February 11, 2015 The most recent NOAA surface analysis chart shows MSWH of 10-11 metres in that area. Mean significant wave height is the average height of the largest 33% of waves out there. That means that roughly 1 in 6 waves are bigger than that.Thanks for the info, that's cool. Again, I hope they scrub the launch so we can get to see the reentry attempt. Link to comment Share on other sites More sharing options...
Albert VDS Posted February 11, 2015 Share Posted February 11, 2015 Wow, three-story heigh waves. This time round I actually hope they'll scrub the launch... I know the next opportunity will be in a couple of weeks, but I'm almost more interested in the reentry attempt than in the mission.Yeah, it's not like those 9 days even compare to the more than 12 years it already has waited.It's too bad a good landing attempt will go to waste.

AngelLestat Posted February 11, 2015 Share Posted February 11, 2015 What's happening with the upper level winds? To my untrained eye, the 250 hPa analysis chart doesn't look much better today than it did yesterday?http://i.imgur.com/19bwXEw.pngWhy you mean, there is always strong winds at those heights..http://earth.nullschool.net/#current/wind/isobaric/250hPa/orthographic=-66.88,9.41,427At least to day the winds blow in the same direction, they can provide 10 or 20 m/s on deltav.

Frida Space Posted February 11, 2015 Share Posted February 11, 2015 Next F9 launch will be on Feb 27th, carrying Eutelsat 115 West B & ABS 3A. Does anyone know if they will attempt a landing?- - - Updated - - -Upper level winds still within limits: Link to comment Share on other sites More sharing options...
Kryten Posted February 11, 2015 Share Posted February 11, 2015 Next F9 launch will be on Feb 27th, carrying Eutelsat 115 West B & ABS 3A. Does anyone know if they will attempt a landing?No, it's right at the upper limit of the performance envelope. It doesn't even have legs. Link to comment Share on other sites More sharing options...
PakledHostage Posted February 11, 2015 Share Posted February 11, 2015 Why you mean, there is always strong winds at those heights..Not necessarily. The animation you posted seems to show the current upper level winds rather than the typical upper level winds. You can clearly see the southerly dip in the jet stream that is currently situated over Colorado in both the analysis chart that I posted and your animation. The jet streams usually aren't that far south or that spread out. Link to comment Share on other sites More sharing options...

Albert VDS Posted February 11, 2015 Share Posted February 11, 2015 So I guess the next barge landing attempt will be with TurkmenSat 1 or Jason 3 at the end of March Link to comment Share on other sites More sharing options...

Kryten Posted February 11, 2015 Share Posted February 11, 2015 So I guess the next barge landing attempt will be with TurkmenSat 1 or Jason 3 at the end of MarchNo official word for either, but Turkmensat is close enough to limit I highly doubt it'll be doable. Jason 3 (built for V 1.0) should have plenty of margin. Link to comment Share on other sites More sharing options...
Motokid600 Posted February 11, 2015 Share Posted February 11, 2015 Why can't they try for a boost back to land? Thats the eventual intention, no? This whole barge stuff is just a proof of concept for the Falcon Heavy I thought. Link to comment Share on other sites More sharing options...

Between having less fuel, only being able to do two burns and the high wave heights, I have concerns about them sticking this landing. Link to comment Share on other sites More sharing options...

It still has to hit a landing point ( can't "land anywhere" like mechjeb , lol ) and if you saw the video the rocket had alot of horizontal speed as it struggled to hit its mark.

It could have exploded on land, but it still would have been in the target area, and everything would have been okay. Link to comment Share on other sites More sharing options...

No danger to civilians even on a pretty much worst case failure? I've seen worse airplane landings. Sure, premission to build a landing pad granted."

bigdad84 Posted February 11, 2015 Share Posted February 11, 2015 I've been getting frustrated that they've been scrubbing their launches..... Now I want them to scrub... I would rather wait 9 more days to see them attempt a barge landing rather than a water landing. We all know they're capable of it. Link to comment Share on other sites More sharing options...
