Fleets of miniature spacecraft may now be closer to liftoff.
To bring this sci-fi vision of 50-pound "micro-spacecraft" and 10-pound "nano-spacecraft" to reality, scientists have now invented a razor-thin skin that can protect craft against the extreme heat and intense cold found in outer space and withstand micrometeoroids hurtling at thousands of miles per hour.

Radar concealment
Military space expert Dr Stuart Eves thinks that future spacecraft are likely to incorporate stealth technology in order to better avoid detection.
"The threat side of this could be implemented by techniques a bit like those used on aircraft, such as using radar absorbent materials, radar reflective materials, or painting the satellite black," Dr Eves, from Surrey Satellite Technology Limited (SSTL), told BBC News.
But the solar panels for powering the satellite would be more difficult to hide from radar. The infra-red signature of a satellite is also hard to conceal.
Dr Eves adds: "One of the other issues is that the ability to track objects in space from the ground extends down to objects about 10cm in size - that's effectively what you can do with existing radars.
"One of the ways of being stealthy is to be quite small and hard to see."
A launch on December 21, 2004
A launch on December 21, 2004 by Boeing with a new "Delta IV Heavy" rocket from Cape Canaveral failed to place a 'dummy' satellite into its intended orbit, but the launch was considered successful by Air Force officials.
The dummy satellite, the purpose of which was to monitor the Delta IV launch, as well as two experimental nanosatellites,provided by the U.S. Air Force Research Laboratory...
Collins also reported, "We now have enough information and confidence in the Delta IV Heavy to move forward with preparations for the upcoming Defense Support Program launch in 2005. The mission has met all its major objectives. The US Air Force - was very, very happy."

PASADENA, Calif., Oct. 19 /PRNewswire-FirstCall/ -- VIASPACE Inc. (BULLETIN BOARD: VSPC) , a company dedicated to commercializing proven technologies from NASA and the US Department of Defense, announced today its subsidiary, Ionfinity LLC, has been awarded a Phase II STTR contract extension and additional funding by the U. S. Air Force to develop, jointly with Aerospace Corp. and the NASA Jet Propulsion Laboratory, a soft ionization membrane to be used as a micro ion engine for micro and nano satellite station keeping. Massively duplicated micro ion engines could also provide station keeping for large satellites.

That was the question I had when I spotted that story.
Why waste all of that on a bogus satellite?
President Dwight Eisenhower approved the U-2 program in 1954. Only four members of Congress knew about it and paperwork was essentially nonexistent.The funds came from a discretionary fund in the CIA directors unaudited budget, Taubman said. It wasn’t until pilot Francis Gary Powers was shot down over the USSR in 1960 that the unique “jet-powered glider” became public knowledge. According to Taubman, “Eisenhower had faith in science. He had openness to technology that I don’t think many other presidents have had. And finally, he had extraordinary patience. And he needed it, because these projects were very difficult to pull off.”
For example, the first 12 launches of the Corona spy satellite ended in failure. Taubman said, “Today, there would never be the tolerance in Washington to sustain a program that had such a high failure rate. It wouldn’t happen.” But it was worth it, according to Taubman. “It probably saved the nation billions of dollars in defense spending,” because it proved that the USSR possessed only a handful of ICBMs, far fewer than predicted by CIA analysts.
“All of this was amazing engineering,” said Taubman. “We’d never done any of this. There were no models. And don’t forget, there were only the most primitive computers at the time. The guys who did these projects were still working with sliderules.” Years later, Eisenhower was quoted as saying, “This bunch of scientists was one of the few groups I encountered in Washington who seemed to be there to help the country and not to help themselves.”
In recent years, the NRO has implemented a series of actions declassifying some of its operations. The organization was declassified in September 1992 followed by the location of its headquarters in Chantilly, VA, in 1994. In February 1995, CORONA, a photoreconnaissance program in operation from 1960 to 1972, was declassified and 800,000 CORONA images were transferred to the National Archives and Records Administration. In December 1996, the NRO announced for the first time, in advance, the launch of a reconnaissance satellite.

Well here are two examples... (and there is the Atomic Bomb as well)

CIA's unaudited budget Hmmmmm

Now from the NRO we get a new policy of openness...

Excerpt... When the United States ceased nuclear testing, laser facilities became even more important for defense research, and the portion of Nova shots dedicated to the weapons program increased considerably. Researchers using Nova continued obtaining high-energy-density data necessary to validate the computer codes used to model nuclear weapons physics.
