  1. Re:Sounds like the 1979 Iran mission, repeated on RKK Energia Confirms Private Trip To the Moon · · Score: 1

    The Titan II booster used for the Gemini missions used hypergolic fuels very similar to the Proton. (Titan II used a 50/50 mix of hydrazine and UDMH for fuel, where the Proton uses strait UDMH; both use N2O4 for oxidizer.) Hypergolics are also used to fuel Apollo service module, the LEM, the space shuttle OMS & RCS, the Souyz service module, simply because they don't require cryogenic storage and they ignite on contact, removing the complexity of an ignition system. I don't they use of hypergolics automatically prohibit man-rating. (That said, the sooner the Proton can be retired in favor of kerolox fueled Angara 5, the better. Proton burns some nasty stuff.) I think they are, in fact, going to use the Proton. In the late 60's, the USSR was planing on using using a Proton to send a Soyuz capsule on a circumlunar flight. (Note that they weren't planing on orbiting the moon, just swinging round the dark side and heading back to Earth, similar to the course Apollo 13 used.) They flew four unmanned test flights, but they were unable to fly a reentry pattern that wouldn't have killed the crew. The plans were shelved after Apollo 8 beat them to it with their lunar-orbital mission.

    Strange that this is what's drawing your ire when the Senate... which as been controlled by Democrats since 2007... hasn't submitted a budget in 2 years.

    The Senate can't submit a budget. All appropriation bills must originate in the House. Senators can advise House leaders what would and wouldn't make it's way through the Senate, but in the end, it's the House's job to get the budget ball rolling.

    Natasha and the Backburner are also awarded for earning enough class achievements, so you don't even need to get lucky with the drop system. You just have to play the respective classes long enough to hit the achievement milestones.

  5. Nothing new on Microsoft Kills Skype For Asterisk · · Score: 1

    We got screwed at work after bought Onfolio. First, they discontinued the pro version we bought and were using in Firefox in favor of a free dumbed down IE only version, then they eventually killed that. Wouldn't mind too much, but they also turned off the activation servers, meaning if we have to reinstall Windows due to, say, a virus, we can't reinstall the copy Onfolio we had bought. I guess we hit the "Extinguish" stage of the business plan.

  6. Re:Skylons? on Skylon Spaceplane Design Passes Key Review · · Score: 2

    They had a plan. Nuke the humans for orbit. After they found out that is in fact NOT a sure-fire plan, they were just winging it.

  7. Not just developers on Do Developers Really Need a Second Monitor? · · Score: 1

    Everyone in my office, a market research company, has two monitors. For development, it's very useful. I have the application I'm working on on one screen and the code open in the debugger on the other. I'm sort of curious: was the monitor taken to give someone else a second monitor (in which case I ask do accounts really need a second monitor more than a developer) or was it for a first monitor (in which case I ask where the previously headless computer came from).

  8. Re:Business 101 on Developer Blames Apple For Ruining eBook Business · · Score: 1

    Apple requires you to charge the same price in-app that you do elsewhere. You can't just do the logical thing and add 30% to the price to cover the Apple overhead.

    AT&T didn't let anyone with 3GSs upgrade. You had to have been at least, what was it, either 15 or 18 months into an existing contract to qualify for an early upgrade at the iPhone 4 launch. Given that the 3GS had only been out for 12 months at the time, no dice.

  11. Re:Leave one in orbit? on NASA Announces Final Homes of Shuttle Fleet · · Score: 1

    Shuttles can only last about two weeks in orbit before they run out of reactants for the fuel cells. They wouldn't last much longer, even if you cut power consumption, because the hydrogen in the fuel tanks would continue to boil off whether your using it or not. Soyuz can stay in orbit much longer due to the fact it gets its power from solar panels and, when docked, directly from the space station.

  12. Re:Can I have it now you are finished with it? on NASA Readies Discovery Shuttle For Final Flight · · Score: 1

    Well, you could just stack the shuttle on the launchpad like they were planing to do at Vandenberg, but then you have to be able to roll the assembly building away.

  13. Re:supply lines to ISS already secure on SpaceX Falcon 9 and Dragon Make It To Orbit · · Score: 1

    An Atlas V HLV can, in theory, put 29,420 kg in LEO, which puts it between the Shuttle's 24,400kg and Falcon 9 Heavy's stated 32,000kg. However, no one's needed a Atlas Heavy yet, so it has yet to be flown.

  15. Re:This has all happened before. on BSG Prequel Series Caprica Canceled · · Score: 1

    My favorite writing blunder was in the back half of the last season. Most fans who watched "Someone to Watch Over Me" were convinced that the Piano Man was Starbuck's dad and Daniel, Cylon #7, which would have helped explain how Starbuck resurrected on Earth and how she started playing "All Along the Watchtower." RDM's take on it, though, was something along the lines of, "Yeah, I can totally see how you guys think that, but the thought hadn't even crossed our minds. Sorry for giving you that idea."

    I still think, in this case, the writers are wrong and the fans are right.

    They had a dedicated Saturn set up for Bomberman with all the multitaps at PAX East. I got a few rounds in; it was pretty epic, but alot of time was spent figuring out what controller was for which guy.

  17. Not quite complete on The Doctor's Every Journey · · Score: 4, Informative

    It does seem miss some instances of time travel in the middle of a story. For instance, near the end of Smith and Jones, he goes back to the beginning of the day to take his tie off at Martha, and during Vincent and the Doctor, there were two round trips from 2010 to 1890, of which only the first leg is reported here.

    OK, I may be over-nerding here even on a nerd topic.

  20. Re:Watched it, impressed! on First Impressions of the 11th Doctor Who · · Score: 1

    If you want an in-universe explanation, I suppose some hand waving could link it to how the Doctor was able to regrow his hand in The Christmas Invasion. I suppose the writers could chalk it up to her being within 48 hours of her (re)generation cycle, so it was just superhealing rather then regeneration. Better explanation, though, is it's a TV show. The writers can make whatever they want happen, and it probably wasn't worth casting an extra actress for a 30 second scene.

    Weight. If you use nuclear power source, you've got to bring your fuel with you, where as with solar, the fuel is already packed away safely in the sun; you just need to bring a collector. Mars, unlike the outer planets, is still close enough to the sun that you get a reasonable amount of power from solar cells, if you have enough square footage, so solar wins the power/weight ratio contest. Besides, these things weren't built to survive the winter at all; the design requirements only called for three months.
