AsteroidShield related news

The New Scientist also has an article about how exploding robots could be sent to determine the composition of Near Earth Asteroids. This would be relevant in developing a proper Asteroid shield. A current project is the Lifeboat AsteroidShield

The Ball Aerospace proposal of many small probes seems cost efficient and worthy of being advocated by the Lifeboat Foundation.

Prospects for Lifeboat space habitat colonies

Posted by in categories: lifeboat, nuclear energy, space

The New Scientist discusses a recent study that advocates using of an ion beam generator on the moon to allow the use of far smaller rockets to move from the moon to other locations in space. The ion beam generator would need several hundred megawatts of electrical power from either a large solar cell array or nuclear power.

I have discussed the need on my website to make gigawatts of power on the moon and in orbit in order to begin serious development and colonization efforts.

An alternative to ion beams would be magbeam, a plasma based approach for accelerating spaceships

Militarization of Space Looming

Posted by in categories: military, space

On CNN:

WASHINGTON (CNN) — China last week successfully used a missile to destroy an orbiting satellite, U.S. government officials told CNN on Thursday, in a test that could undermine relations with the West and pose a threat to satellites important to the U.S. military.

According to a spokesman for the National Security Council, the ground-based, medium-range ballistic missile knocked an old Chinese weather satellite from its orbit about 537 miles above Earth. The missile carried a “kill vehicle” and destroyed the satellite by ramming it.

Hawking hopes to go into space in 2009

Posted by in category: space

From Yahoo News:

Astrophysicist Stephen Hawking says he wants to undertake a zero-gravity flight aboard an aircraft this year as a precursor to a journey into space.

“This year I’m planning a zero-gravity flight and to go into space in 2009,” he was quoted as saying in The Daily Telegraph newspaper.
