I have been looking for that mission when the X37-B launch were announced back then (it has been delayed more than once yet) and ended up with two options: One, they have a clear idea for that and I was totally unable to even guess at it. Two, they have no idea either. The only even remotely possible reason would be to return things found in orbit. Is there something up there they want to grab and return? It would've to be something fairly small or a small part of something larger, mind you. One option would be that it refuels and replenishes reconsats, as well as possibly boosting their orbits. This speculated it is a space bomber: http://www.msnbc.msn.com/id/3077821/ And the Boeing artwork of one with a RV riding over either inner wing would suggest that's the case also: http://msnbcmedia2.msn.com/j/msnbc/1...2.standard.jpg But you would need a large number of them in orbit to get one within range of the intended target at the time you wanted to hit it due to orbital mechanics. Also, since the X-37 is intended for a 270 day mission, what exactly do you do with the RVs when the vehicle heads home for refurbishment and relaunch? In this other piece of artwork, the X-37 is shown with a solar array deployed and something cylindrical down in the cargo bay: http://space.skyrocket.de/index_fram..._sdat/x-37.htm But it doesn't look like a camera...ASAT weapon? You could carry a nuclear warhead inside the cargo bay and have the vehicle land at the end of its mission with that aboard, but that would be a direct violation of the Treaty Of Outer Space, and a pretty treacherous step to take as it could then be used as a first strike weapon. Still, this thing is a holdover from the second Bush administration, so who knows? They tossed the ABM Treaty, so maybe the TOOS was on the chopping block also? "Rapid sortie photo-reconnaissance" launched on an Atlas V sounds a bit crazy, if you ask me. There *must* be simpler and cheaper and more rapid ways to do that. Or they have some reusable black launcher in the works. Since the X-37B doesn't seem to have much acceleration ability on its own given its internal propellant tankage, such a launcher would have to be able to get it up to around 80% orbital velocity to work.

The USAF has been talking about space-testing (and returning) components, which sounds somewhat reasonable in itself (especially when you've got components you can't just mount to the outside of the ISS for obvious reasons). But even this sounds somewhat like an excuse.

Consider the possibility that the "X" in the vehicle name really is accurate: it's an experimental vehicle, not directly a prototype for a particular operational vehicle (which would have a "Y" prefix). |

A lot of the other military X-planes that have been recently made are prototypes for operational weapons systems. What makes X-37B interesting is that originally NASA was supposed to have some use for this spacecraft also in the X-37A version. Here's some more info on it: http://www.designation-systems.net/dusrm/app4/x-37.html Pat |

Maybe it's me, but it seems rather straight forward that the idea is to lower cost to orbit with a reusable spacecraft. Which would enable the military, and civilian sector, to do whatever they pleased in the future due to the lower costs. Why would anyone think the X-37B is in it's final form, or scale? All of the others X planes were scale versions. Umm, no they weren't. Most where in fact the only version. I've done my homework. They were all testbeds, not prototypes. There's no reason to believe the X-37B is any different.We can't assume the final form will be manned or unmanned, The Lockheed Martin X-33 was an unmanned, sub-scale technology demonstrator for the VentureStar http://en.wikipedia.org/wiki/X-33 The X-43 is an unmanned experimental hypersonic aircraft design with multiple planned scale variations meant to test different aspects of hypersonic flight. http://en.wikipedia.org/wiki/X-43 The unpiloted X-40 was built to 85 percent scale to test aero dynamics and navigation of the X-37 http://en.wikipedia.org/wiki/Boeing_X-40 The Orbital Sciences X-34 was intended as a low-cost testbed to demonstrate "key technologies" integratable to the Reusable Launch Vehicle program. http://en.wikipedia.org/wiki/Orbital_Sciences_X-34 The Boeing X-37 Advanced Technology Demonstrator is a demonstration spaceplane that is intended to test future launch technologies while in orbit and during atmospheric reentry. It is a reusable robotic spacecraft that is a 120%-scaled derivative of the X-40A. http://en.wikipedia.org/wiki/X-37B My point is that the assumption around here is that all these attempts were failures, got canceled, and that's the end of the low cost reusable story. I say, and it seems rather obvious, that instead, the various technologies which /were/ successful are in the process of creating the latest attempt. The X-37B. All these programs just didn't get ****-canned. The best of it went to the Pentagon black budget and low cost reusable technology is not just alive and well, but quickly catching up...imho. From what I can gather it seems pretty clear the military has cherry-picked the successful technologies from the various other 'canceled' projects, the X-33, X-34 and X-43, and have run with them with the X-37B. The next space war will be won by the side that can replace their space assets, taken out on 'day one', the fastest. There's nothing new there. We've known that for a few decades. But my point is that our tactics are in the process of changing. The Operationally Responsive Space (ORS) program started in 2003 or so, and marks the shift away from the large nuclear war hardened satellites, to the small easily replaceable micro satellites they wish to begin building. Not having large military assets in space translates to ... not needing....men in space in the future. My point....and I wish people here would actually try to discuss the point, not just holler "you're full of ****". I mean once in a while it would be nice to have an adult conversation around here. My point, is that the X-37 B looks quite suitable for that kind of military tactics. While The Stick and Heavy would be exactly the opposite of what the military could use. http://www.weeklystandard.com/Conten...6/076oeyqy.asp All these things also point to a quick demise of the notion of returning to the Moon. -- Greg Moore Ask me about lily, an RPI based CMC. |
