Unobscured Vision Posted February 25, 2016 Share Posted February 25, 2016 Got my chili-n-cornbread, nibbles and my sports drink. Arm is propped up in as comfortable position as I can get it. Eating my chili, trying not to make a mess. Livestream tab is pinned. Think I'm good to go. Draggendrop 1 Share Link to comment Share on other sites More sharing options...

Beittil Posted February 26, 2016 Share Posted February 26, 2016 (edited) A NSF user did find a NOTAM for today and posted that over at NSF: Quote NOTAMs valid for Friday night: !SUAE 02/629 ZMA AIRSPACE R2933 ACT 5000FT-UNL 1602262311-1602270154 !SUAE 02/628 ZMA AIRSPACE R2934 ACT SFC-UNL 1602262311-1602270154 This would put it at 6:11pm EST (fri 26th) / 11:11pm GMT (fri 26th) / 0:11am CET (sat 27th).

DocM Posted February 26, 2016 Author Share Posted February 26, 2016 (edited) USAF has a weather forecast up for Saturday, and SES is taking *possibly* next week, but nothing firm. Meanwhile, @NASASpaceflight First stage is going to pull some massive Gs slowing down. Multi-engine landing burn too! :-O Because it's coming in hot. Its unknown if it's 3 engines and divert* to touchdown, 2 outer engines and divert to touchdown, or 3 engines down to the divert then cut to 1 engine for touchdown. High G's whichever. * the ballistic path splashes the stage into the drink. The divert after landing burn start takes it over the Landing Zone or ASDS. anthdci 1 Share Link to comment Share on other sites More sharing options...

Draggendrop Veteran Posted February 27, 2016 Veteran Share Posted February 27, 2016 Misc data.... Issues with supercold fuel again halt SpaceX launch Quote A design change in SpaceX's Falcon 9 rocket that requires its liquid oxygen fuel to be kept cold even by rocket-science standards again proved tricky to implement at the launch pad Thursday, delaying liftoff of a communications satellite for a second straight day. The countdown for the SES-9 satellite launch from Cape Canaveral Air Force Station, Florida, was halted with only 1 minute, 40 seconds to go due to problems loading the liquid oxygen into the rocket, said John Insprucker, SpaceX's Falcon 9 product director, during the company's launch webcast. No further details were given about the problem, which Insprucker said SpaceX engineers would investigate. A new launch date has not yet been assigned. In most rockets that use liquid oxygen fuel, as with earlier versions of the Falcon 9, the LOX is loaded hours ahead of time. But the performance boost required for launches like that of the geostationary SES-9 led SpaceX designers to call for "densified" liquid oxygen — fuel subcooled so more of it could be kept in the same size tanks, allowing the newer F9 to throttle up its nine first-stage Merlin 1D engines, as well as leaving enough extra fuel for the stage to return to Earth for potential re-use. That latter capability was proven in the new design's first flight, in December, when its first stage successfully touched down at a CCAFS landing complex five miles from the launch pad. But while the rocket industry has decades of experience dealing with "normal" liquid oxygen at temperatures down to -300 degrees F, keeping the Falcon 9 Full Thrust's fuel at the required -340 degrees F has proven much trickier. Even just keeping the fuel in the F9FT's tanks longer than tens of minutes lets it warm up too much. So now, the fuel is loaded in the last minutes of the countdown. Those problems delayed the pre-launch static fire test in December and led SpaceX engineers to call off Wednesday's launch attempt half an hour before launch and minutes before the webcast was to have started — with a 40 percent chance of no-go weather then, the fear appears to have been that the odds of a weather delay after fuel loading were too high. The late fuel loading was where things went wrong Thursday. As the clock ticked down from T minus 2 minutes, engineers on the countdown audio net requested a hold at T-1:40. That was quickly followed by an abort call from the launch director — even though the launch had a nominal window of around an hour and a half, Wednesday's apparent fear became Thursday's reality: a halt that late in the countdown wouldn't leave enough time to re-chill the fuel to the required, densified temperature. It also appeared that the fueling was taking too long, leading to the hold request. http://www.wacotrib.com/blogs/joe_science/issues-with-supercold-fuel-again-halt-spacex-launch/article_88079414-dc36-11e5-a64f-8b9ca7b59bdb.html first this..... then this....

PaulRocket Posted February 28, 2016 Share Posted February 28, 2016 (edited) @DocM Do you know anything about their plans to land with more then one engine? Usually they use 3 for boost back and reentry and 1 for landing but now the rumor is on reddit that they'll use more then 1 engine for landing... Maybe that way they will save fuel? Would be an extremely aggressive suicide burn.
