The Chinese government sees the U.S. as a threat because of the nature of our elections, which allow loud-mouthed braggarts who want to claim China as an enemy so to gain political power. Seeing these elements could gain control at any election, China will work on weapon programs that can quickly sink our Pacific fleet and replace it with their own, if necessary. <br /><br />Given the reduced growth and the need to increase social and infrastructure spending to keep its own populace in line, something has to give. That will end up being China's space program, especially as they're seeing the other Powers losing interest in space.<br /><br />Rob H.Acacia H.https://www.blogger.com/profile/07678539067303911329noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-4980639379437027152012-05-28T03:04:53.947-07:002012-05-28T03:04:53.947-07:00"China is finding its growth is faltering and..."China is finding its growth is faltering and will likely in turn cut ITS space program..."<br /><br />China might hold its space development budget to a real increase of only 10-20% per year.<br /><br />But I think it highly unlikey.Ian Gouldhttps://www.blogger.com/profile/04352147295160200128noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-44937590801688020032012-05-27T20:36:19.853-07:002012-05-27T20:36:19.853-07:00That makes sense.

I remember how things bounced about at NASA... though initially I bought into the whole Constellation program test flight, which was basically a waste of money intended to delude people into thinking progress had been made. It's a pity that politics once more got in the way of the Space Program... and I must admit that one of the things I love about SpaceX is how this one company that so many deride as "not ready" and "amateur" has created a rocket that proved viable and able to reach the ISS on its third test flight (and second for the Dragon capsule).<br /><br />What's more, look at the innovation that SpaceX has put into Dragon. Everyone has used rocket-towers that get ejected after launch and are not reusable. SpaceX? They are building it into the sides of the rocket for multiple purposes: emergency ejection for nearly all stages of flight, and then once the capsule is done it's used (with parachutes) to slow its descent and allow for a precision landing that's far safer than dropping the capsule in the ocean or slamming into the ground like the Russians do.<br /><br />Hell, I've been half-expecting sabotage from agents working for the Republicans to try and undo this hard work with a fiery explosion just to make Obama look bad and kill private space industry. But perhaps that's just my cynicism ramped up to 100.<br /><br />Naturally, Republicans will dismiss this accomplishment and claim that it's private industry, not Obama's funding. And they may even try to cut the budget for NASA further claiming "well, they don't need it. Let's have private industry do everything out of their own pockets." <br /><br />But I can't help but think SpaceX with Falcon and Dragon have managed to catch the hearts and imaginations of Americans... much like Apollo once did. Here we have a private company that is doing things differently than NASA... and proving it can be done. And Republicans will have a devil of a time trying to dismiss this accomplishment. After all, this has sparked interest in space and science... and attempts to dismiss it is a slap in the face of private industry, the cornerstone of what Republicans claim they're for. (They're not. They're for Oligarchy. With their buddies in control.)<br /><br />Given that Russia's space program is decaying and falling apart, the European Union is on the verge of being sundered, and China is finding its growth is faltering and will likely in turn cut ITS space program... it will be private industry that leads humanity into space in the 21st century. I just wonder what form it will take.<br /><br />Rob H.Acacia H.https://www.blogger.com/profile/07678539067303911329noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-41562016362966541412012-05-27T19:16:59.624-07:002012-05-27T19:16:59.624-07:00Ian/Rob,

Although CCDev funding later came from the Recovery Act, CCDev was initially proposed at the end of Bush's term. Both COTS and CCDev came about under Bush. Mainly due to the reforms attempted by Sean O'Keefe, who Bush appointed to try to control NASA's costs.<br /><br />The problem was he actually tried to do what he was asked to do, not what they wanted him to do. Rookie mistake. Low cost programs like COTS, and proposing man-rating a commercial launcher instead of building an over-priced Big Rocket shuttle-replacement. The primary NASA contractors (especially ATK, which was being excluded from the trough) and all the shuttle operations people hated him, so Bush replaced him with an ATK-approved Mike Griffin, who promptly cancelled most of the big science missions (*) and pushed Constellation's Big Rocket, with emphasis on throwing money at ATK.<br /><br />(* Jupiter Icy Moons Orbiter, Terrestrial Planet Finder, Space Interferometry Mission, and cut life-science by 80%.)<br /><br />Commercial Crew, I suspect, only came about because of they realised that Constellation's Ares rockets would be too expensive to service the ISS.<br /><br />Bolden (or probably Lori Garver) convinced Obama to return to O'Keefe's basic idea. Kill the hideously overbudget/overschedule/unsafe Constellation and move all launch operations to commercial launchers, focus NASA on deep space human and science missions. Of course, that go the same response as it did the first time, (no Big Rocket, no pork for Primes, no safe jobs for shuttle-ops) and Congress forced another Big Rocket onto the budget, sucking up all funding that could be used for something actually interesting.<br /><br />Personally, in light of the publicity surrounding Dragon, I'd like to see Obama point out the contrast between SLS funding and the money given to SpaceX (about 3-5%), and contrast the relative progress, then announce that he's officially directing NASA to conduct SLS in the same fashion. To have multiple competing aerospace companies trying to build the 70ton launcher under fixed-price fixed-milestone contracts. From what I remember of the wording of SLS's enactment, they could do this and still be complying with the letter of the law, so he wouldn't need any Congressional authorisation. And if the Big Rocket pork faction in Congress pushed new wording that prevented Obama's directive, he could veto it, just as he threatened to do when they defunded CCDev.<br /><br />(tryICT XIII - When Ice 9 Tea is not enough.)Paul451https://www.blogger.com/profile/12119086761190994938noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-23689485274477767652012-05-27T16:33:54.031-07:002012-05-27T16:33:54.031-07:00Technically that says it was funded under ObamaSti...Technically that says it was <i>funded</i> under ObamaStimulus.

One pressurised with an inert atmosphere, separated from the rest of the station by an airlock to prevent contamination. Astronauts would get their air via face-masks, which would also protect their eyes/ears/lungs from crap floating around (probably wear simple dust-suits as well.) Lets them do stuff they can't risk inside the station-proper, such as anything that produces dust or other small particles, or weird smells, but which can't tolerate being outside. Hoses from the face-masks would simply plug into outlets along the walls, which run off the stations regular life-support systems.<br /><br />(Basically, a giant version of the glove-box they currently use for such things.)<br /><br />The second would be unpressurised, but would make for safer EVA's since there's no risk in losing tools (or astronauts), and the capsule itself handles much of the thermal regulation and micro-meteorite protection, allowing much simpler low-maintenance spacesuits. Which allows astronauts to work on things without it bringing them into the station, and without everything else on the station coming to a halt to monitor the EVA. As with the face-mask in the pressurised workshop, if the EVA suits could be plugged into outlets along the wall, offloading air-supply, power and thermal requirements to the module's and station's life-support systems, it would make the suits even simpler. Outer hatch could be large, and simple since it doesn't have to hold pressure.<br /><br />In the case of the ammonia tank, they'd bring it in the EVA-shed, then pull it apart to find the failed part. (Valve?) Then they could send that part back to Earth, or take it into the pressurised workshop to run tests or fix it themselves.<br /><br />(Guy on NASAwatch makes a point that the ISS doesn't even have a washing-machine. Clothes are disposable. Which is very retro-futuristic, I guess, but bodes ill for long-term space habitation when we've spent $100 billion on a space station, but haven't done the most basic work on how to live in space long-term.)<br /><br />(rislam 1099: Harry Turtledove's new alt.history series.)Paul451https://www.blogger.com/profile/12119086761190994938noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-77101698763771114592012-05-26T18:24:09.412-07:002012-05-26T18:24:09.412-07:00...I remember that scene.

Though let's be honest: if you're going to have an exploration vessel, you don't want a capsule. You want something a little bigger. In essence, you want a mobile space station module... preferably something with a centrifugal section for sleeping in so that astronauts have several hours of apparent gravity each day to reduce bone loss.<br /><br />It would be funny if the Dragon Heavy comes out and starts ferrying even more components to the ISS, like said segment for centrifugal rotation, so they can study its effects and if it will help lessen the damage of prolonged stays in space. While the ISS was a waste of money initially... once private industry gets involved, I could very well see it coming to actual use. If only because private industry likes to get some level of profit back form investments.<br /><br />Rob H.Acacia H.https://www.blogger.com/profile/07678539067303911329noreply@blogger.comtag:blogger.com,1999:blog-8587336.post-2179495473081041422012-05-25T22:13:45.677-07:002012-05-25T22:13:45.677-07:00Oh, Orion will carry up to 4 passengers.
