DailyTech's International Space Updates for January 2007

Some experts seem to agree that it is only a matter of time before an asteroid or meteor strikes Earth in the future. While millions of them are aimlessly floating around in space, 200,000 to 400,000 of them come within range Earth, according to reports. That is why NASA astronaut Edward Lu wants NASA to deploy a spacecraft which would be able to divert asteroids so they will not run into the planet. In theory, the craft's gravitational pull would change the asteroid's orbit. UK researchers are planning on using a superior telescope located in Hawaii to help locate Earth-threatening asteroids.

India has successfully recovered the Space capsule Recovery Experiment (SRE-1), a capsule that has been orbiting around the Earth at an altitude of 637km. The SRE-1 floated in space for 11 days before splashing into the Bay of Bengal earlier in the week. The Indian space agency used the SRE-1 to test its ability to accurately track and recover a space capsule landing back on Earth. The head of the team that created the capsule said that “the mission is a great success.”

Chinese space officials still continue to claim that its anti-satellite test is not a hostile act. The Chinese government confirmed that on Jan. 11 it launched a missile aimed at destroying an aging weather satellite, and the test has the United States and Japan worried. While the Chinese previously discussed its plans with U.S. Officials, both the Japanese and U.S. Governments want clarification on the future intentions of the Chinese.  With some form of a space war on the minds of many government officials, this recent incident only has more people worried.

Less trivial than what I had in mind while I was thinking of it, which is the laser's the military would want to use to slice up ICBMs. I figured the distance would be equivalent, but the target softer.

And perhaps that Boeing they're outfitting with a laser could pop off satellites while in a climb attitude? At altitudes in the Flight Level's the thickest part of the atmosphere is beneath the plane.

Of course, this is assuming they ever get that thing to work properly. :)

You referring to the US ABL (Airborne Laser) programme? If so, you'll probably be interested in this analysis:

Very interesting.. Well, since those interceptors at Vandenberg & Greely haven't done too well at actual interception of ballistic missiles it's good to know they're not entirely useless.

In fact, the cynic in me suspects now that ASAT missions were of key consideration in their design. I've also read about agencies like the NRO and their slush funds. Nothing would surprise me.

Thanks for the link.
