Unmanned sail prototype prepares for launch

A prototype of an unmanned sailing ship will begin a test voyage this fall.

Although Harbor Wing will operate without a captain and crew by sailing on a pre-programmed course, “the man is always in the loop,” Ott said. An operator, seated at a computer that could be hundreds of miles away, can control the craft with keystrokes that relay commands via satellite. The transmission gap, from order to receipt, is only 18 seconds, which “on the open ocean is not much,” he said, “so you have very close control.”

NASA about to decide on its shuttle heavy-lift replacement

NASA is about to decide on its shuttle heavy-lift replacement, and it looks like it will be almost entirely shuttle-derived.

As I have said previously, this rocket will almost certainly never fly. NASA has to start over after spending billions and years developing Constellation, and is being given less money and time to do it.

And even if I am wrong and this rocket does fly, I bet it will do only one flight and then be retired as too costly.

Sheila Jackson Lee Likens Islamic Radicals to ‘Christian Militants’ in U.S.

An idiot speaks: Congresswoman Sheila Jackson Lee (D-Texas) yesterday equated Islamic terrorists with “Christian militants” in the United States.

Since 9/11 Islamic terrorists have carried out more than 17,000 attacks, killing tens of thousands. In that same time, you could count on one hand the number of attacks by “Christian militants,” if that many. For Representative Lee, it seems it is hard for her to tell the difference.

National Speleological Society responds to the demand that all caves be closed to protect bats

The National Speleological Society has responded in strong opposition [pdf] to the demand by the Center for Biological Diversity that all caves on public land be closed to protect bats.

Calling for blanket cave closures across the U.S. is unnecessary, unenforceable, and counterproductive. While cave closures on some federal lands have been implemented, particularly in the eastern U. S., there is no evidence that this action has done anything to contain [white nose syndrome] (WNS). Most people working on WNS understand that bat to bat transmission is overwhelmingly the primary method of transmission, and administrative closing of caves and mines does nothing to prevent that.

ESA controllers buy time to solve problems on comet probe Rosetta

This ain’t good. One of the reasons ESA controllers recently put the comet probe Rosetta into hibernation for two and a half years was in order to buy time to solve a serious technical problem.

Mission managers said the hibernation will permit Rosetta to rest its four reaction wheels, two of which have shown signs of degradation. The satellite needs three to function, and one of the two problem wheels will be used only as a spare when the satellite is awakened in January 2014 in preparation for its approach to a comet.
