Airforce Lalunches another spy plane


On the heals of the historic mission when in December the X-37B became the United States' first unmanned vehicle to return from space and land on its own. Now a second Boeing-built X-37B Orbital Test Vehicle, or OTV, left Cape Canaveral, Fla. atop an Atlas V rocket. The X-37B, which was originally a NASA project, has the potential to pick up where the space shuttle program will leave off, least that is what Boing is saying - the Air-Force's position is that the program "has the potential to make space experiments more affordable. But the lack of clear mission statements past the overt, has lent the X-37B program an air of intrigue. Speculation has lead to suggesting the OTV may facilitate the development of combat and weapons systems. While others have suggested that the unmanned craft could be used as an orbital spy vehicle.

The latest mission is scheduled to last about 270 days, but the Air Force said that might be extended. The first craft stayed in orbit 224 days.

Air Force's Scare-Mongering Space Ad - Fear Mongering at its Best!

When I first saw this commercial, I burst out laughing. I really thought it was a joke. You see this satellite in low earth orbit thats suppose to be a GPS or communication bird and the orbit barely looks high enough to even be that of the ISS and in comes a rocket on a clearly balistic trajectory!??? Excuse me? But it seems the AirForce is serious but more serious about generating fear and praying on those that do not understand clearly the dynamics of the systems they use daily. The goal, clearly is to not keep you better informed. And the funny thing is who is running the commercial gleefully? The Sci-Fi channel...It played while I was doing this article during Dr. Who of all things....lol

Wired is taking on the armed forces media with it's latest foray into propaganda. At question is the air-force's commercial, about the perils of an attack in space, which does more than stretch the truth, it violates quite a few laws of physics. The commercial says:

"What if your cell phone calls, your television, your GPS system, even your bank transactions, could be taken out with a single missile?" the military ad asks. "They can."

Well, No, they can't. Not unless there's some new missile out there that can strike dozens and dozens of targets, spread out over thousands and thousands of miles. As the article points out "Communication, television and navigational systems are handled by different arrays of satellites." And each set of satellites is thousands of miles from the other. At least ten thousand miles, for example, separates the arrays of communications and GPS satellites. Systems like the GPS satellites are in fixed or stationary obits called MEO or medium Earth orbit which are 12 thousand miles above the earth's surface. Still others are in fixed or stationary obits called geo-stationary which are twice that far out. There's no missile that can hit two targets that far away from one other. (In fact, there's no anti-satellite missile, taking off from Earth, that can even reach GEO or MEO. Even the much vanted Chineese satellite killer reached only 540 miles. But should such a missle someday be invented that could reach and kill a high flying satellite no system depends on just one bird let alone several systems. Even today, satellites fail or are rotated out of service. Very few people even notice when this happens because of the redundancy of the system. And for what it is worth many systems like banking use terrestrial fiberoptics as backup, so that even if the complete satellite system went down, the could continue to operate.

It is clear that the Air Force is preying on the lack of public understanding of the threat (and space in general) in an attempt to convince voters that space is important too and only the US Air Force can protect America in space.....
