Kulebron Posted February 12, 2015 Share Posted February 12, 2015 I don't understand, where did they go? LOE or L1? Is there a page with mission profile described in dry language? Link to comment Share on other sites More sharing options...
Albert VDS Posted February 12, 2015 Share Posted February 12, 2015 DSCOVR is going to be parked into L1. Link to comment Share on other sites More sharing options...

Kryten Posted February 12, 2015 Share Posted February 12, 2015 Did they stop trying to land on the barge?For this attempt, yes. Waves were waaay too high. Made controlled water landing. Link to comment Share on other sites More sharing options...

Aethon Posted February 12, 2015 Author Share Posted February 12, 2015 (edited) Everything you ever wanted to know about solid rocket boosters, but were embarrassed to ask. http://www.nasa.gov/sls/space-launch-system-boosters-101.html#.VNzhTfnF-Yc Edited February 12, 2015 by Aethon Link to comment Share on other sites More sharing options...

RainDreamer Posted February 12, 2015 Share Posted February 12, 2015 Poor whatever lies behind the booster during that test. I wonder how the area around rocket test sites looks like. Would everything be like, burnt to a crisp, all the time? Link to comment Share on other sites More sharing options...
bigdad84 Posted February 13, 2015 Share Posted February 13, 2015 Is it wrong of me to say SpaceX is the only company I really care to see launch rockets anymore....? Just because they attempt what others think is crazy. I'm gonna love the day that SpaceX is landing their rockets back at the pad while ULA is just dumping more stages into the ocean. You would think that they would be worried by now?EDIT: Outside of NASA, but that's not for a couple more years. Link to comment Share on other sites More sharing options...

Aethon Posted February 13, 2015 Author Share Posted February 13, 2015 Wish they had a longer, more detailed version.Agreed. There's a lot of information there that goes by pretty fast. I would enjoy a longer version.If you haven't, follow the NASA link in that post for an article with deeper treatment. Link to comment Share on other sites More sharing options...
softweir Posted February 13, 2015 Share Posted February 13, 2015 I thought I read that today was the last day that they could launch before the Moon's gravitational influence would have affected DSCOVR's delta-V budget beyond allowables? Presumably that means that the Moon does occasionally get close enough to the second stage's orbit to affect it significantly?DISCOVR has its own thruster to take it a long way beyond what the 2nd stage can reach. The 2nd stage hasn't enough dV to reach escape velocity so will fall back long before a lunar encounter, but can get DISCOVR to an orbit from where its own thruster can take it to L1. So the moon could have been too close to DISCOVR - but nowhere near the 2nd stage. Link to comment Share on other sites More sharing options...

Every rocket climbing to space on a pillar of fire is by very definition awesomeness incarnate . Which one you like best is a matter of personal preferences of course. I, for one, love Ariane 5 and Delta IV Heavy almost as much as Falcons. Link to comment Share on other sites More sharing options...

PB666 Posted February 13, 2015 Share Posted February 13, 2015 Probably?Maybe we should wait until the thing flies its official mission before saying what it will do after.Hah, 21 days in that thing is asking alot, but it won't reach mars.........Its a hype train.

YNM Posted February 13, 2015 Share Posted February 13, 2015 Excuse me if I keep posting photos from the launch, but it was just AWESOME.https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xpa1/t31.0-8/1782281_310351342508928_7825299634711897288_o.jpgI mostly liked the ones in the video where the chase cams resolved the engines higher up. Looks cool... all that power of nine, not just a few (2-5) or some solid rocket !Is it wrong of me to say SpaceX is the only company I really care to see launch rockets anymore....?

Any kind (well, probably apart from stove and refineries...)Regarding launchers, the Vega IXV launch was so fast... Is it due to TWR ? SLT ? Is that save (I mean, can anyone give acceleration data ?)it will be a video on the first stage splashdown?The seas were deemed too difficult to send out an uncrewed automated ship that survived a rocket crashing into it with barely a scratch.I rather doubt there were any russian trawlers with dashcams nearby. you'd get a bright bolide instead, had there were any russian cams... ?

I was under the impression that the Falcon's second stage put DSCOVR into its current 170 km x 1.37 million km transfer orbit and was therefore also in that orbit. I unferstood that DSCOVR's own thrusters would merely bump it from the transfer orbit into "orbit" around Earth-Sun L1. Link to comment Share on other sites More sharing options...
