Proposal for an orbiter/lander mission to Enceladus (circa 2013): https://www.dropbox.com/s/n36ok8q2r2j88u9/EOLM_sanitized.pdf?dl=0
Minor comment about the space race. Lost does an excellent job describing why the Soviet Lunar Program failed, but one thing he doesn't mention is that the Soviets kind of put the ball in the USA's court by not embracing the competitive nature of the space race early on. By not declaring an ultimatum before Kennedy's speeches to Congress and Rice, the Soviets effectively lost the initiative and allowed the Americans to set the terms of the subsequent space race, which they did to deliberately force the Soviets into a contest they were unlikely to win (i.e., a Moon mission requiring much more technical expertise where the Americans were ahead, as opposed to the Soviets whose strengths lie mostly in launch vehicle technology).
At least that's my understanding of it. Discuss.
SLS has passed Critical Design Review, and with that hurdle over NASA has dropped the von Braun paint scheme for a more sensible natural orange. Lots of cool concept images here.
Some additional detail:
Anyone who has a clue about rocketry know if this is significant?
It's has more specific impulse, so you need less propelant to get the same delta-V. That means your spacecraft can be a lot smaller (most of the mass of spacecraft/launch vehicles is propellant).
Of course, since it's an ion engine, you can't use the most efficient trajectories (such as Hohmann transfers), which somewhat reduces the delta-V advantage. Also, you need a shitload of power for large ion engines, which means either all the solar panels or a reactor.
I kinda think the N1 could have been made reliable under better conditions than the historical N1-L3 program had to go through (funding shortages, opposition from Chelomei etc.)
This contained info I didn't yet know about MOL:
For example: I had no idea there was a Titan launch in support of MOL. Props to AST for being a nerd's nerd.
Word has it that CRS-2 contract decisions have been postponed, but there are rumors that Boeing is out and NASA was pleased with Sierra Nevada's proposal.
Whoah, that's big goddamn news! Was SNC's submission Dream Chaser or related, or another capsule?
I think it was Dream Chaser. This is all hearsay, but I've heard SN did a shitload of work on it since the last CRS.
That would be super cool.
Our favorite plagiarist goes full Wehraboo:
How the fuck would it not be a Nazi weapon? It was a weapon developed and used by Nazis --> is Nazi weapon. They didn't even steal it from the Czechs like they did half their other shit.
Interesting article about health effects of zero g.
Maybe people are confused that the Nazi's spent so much time and money devopling useless rockets (not harmless, but the cost-effective equivalent of bombing British towns with incediary recihmarks) that it HAD to be an Allied sabotage project
Kinda like how Ferdinad Porsche was a decorated Soviet Sabotuer
I mean, nothing says feeding your enemy healthy servings of bullshit like producing a 60 ton tank with 100mm of front turrent armor
A bunch of stuff about Elon Musk's newest rocket got leaked;
NASA got $19.3 billion in funding for 2016; http://spacenews.com/nasa-receives-19-3-billion-in-final-2016-spending-bill/
$750 mil more than they requested.
SLS got a shitload more $ than requested.
Also $175 million for a Europa mission; to include lander!!!!!
fucking goddammit lost now I have to go change my pants
John McCain is very angry that the ban on purchasing RD-180s might get lifted.
Elon Musk @elonmusk 4h4 hours ago
Just reviewed mission params w SpaceX team. Monte Carlo runs show tmrw night has a 10% higher chance of a good landing. Punting 24 hrs.
Falcon 9 successfully landed at Cape Canaveral.
