Another Slip

SpaceX’ next launch attempt has apparently been slipped to mid-February, due to a thrust-vector control issue. The static test firing will still occur this weekend, though.

Space Law Bleg

Did the Chinese violate any treaties about not making messes in space when they destroyed their own weather satelllite? My dim understanding is that this issue remains unsettled in the Liability Convention, due to an inability to agree on a definition of the word “debris.” Any space lawyers out there more up to date?

I’d think that, at a minimum, if any of the bits strike someone’s satellite, or ISS, that the Chinese could be held liable under the OST. If it could be proven that it resulted from this event, that is (probably a difficult thing to do).

Order Now

Frank J. has a new book out. He calls it the dumbest book ever written about the Bush administration. Hard to believe, for anyone who’s ever read Ivins.

It’s a compilation of many of his blog posts for the past few years. I guess I should finish mine.

Molecular Machinery

Behold: molecules that can walk and deliver payloads in a straight line. This could lead to some interesting breakthroughs.

[Update a few minutes later]

Here are some interesting pictures of semi-conductor junctions and charge carriers, at the nano-scale:

“There’s no major surprises here,” says Andreas Heinrich of IBM Almaden Research Center in San Jose, California. “But the fact that they are actually imaging the electric properties is a big step forward.” Surprises may show up when de-vices shrink below around 50 nanometers, Heinrich says, because dopant atoms will be so scarce that their individual positions may affect the de-vice’s function. Tomihiro Hashizume of Hitachi’s Advanced Research Laboratory in Hatoyama, Japan, says the ability to see precisely how charge carriers move “will be indispensable for the further progress of de-vice miniaturization.”

A surgical microbot.

The scientists are designing the 250-micron de-vice to transmit images and deliver microscopic payloads to parts of the body outside the reach of existing catheter technology.

It will also perform minimally invasive microsurgeries, said James Friend of the Micro/Nanophysics Research Laboratory at Australia’s Monash University, who leads the team. The researchers hope the de-vice will reduce the risks normally associated with delicate surgical procedures.

The piezoelectric approach seems promising.

How much further behind will be nanobots?
