The Asian space race is moving along slowly, but steadily – and China is in the lead, with technology that could give it a military advantage over the US.

In this 1960 photograph, the seven original Mercury astronauts participate in US Air Force survival training exercises at Stead Air Force Base in Nevada. Pictured from left to right are: L. Gordon Cooper, M. Scott Carpenter, John Glenn, Alan Shepard, Virgil I. Grissom, Walter Schirra, and Donald K. Slayton. Portions of their clothing have been fashioned from parachute material, and all have grown beards from their time in the wilderness. The purpose of this training was to prepare astronauts in the event of an emergency or faulty landing in a remote area.
As firms prepare to launch the space tourism business, one study warns that the soot from the suborbital crafts' hybrid rocket motors could collect in the stratosphere and warm the poles.
Seen here is a full-scale model of one of the twin Voyager spacecraft, which was sent to explore the giant outer planets in our solar system. Voyager 2 was launched August 20, 1977 followed by the launch of Voyager 1 sixteen days later. Both spacecraft visited Jupiter and Saturn with Voyager 2 continuing its journey to Uranus and Neptune. In spring 1990, Voyager 2 transmitted images looking back across the span of the entire solar system. Both Voyagers continue to explore interstellar space.
Besides water, frigid craters at the moon's poles hold other resources that astronauts might be able to use to sustain lunar bases. There's even a bit of silver.
Orionid meteor shower will conclude Thursday night as the Earth finishes traversing through the debris field that follows Halley's Comet.
This infrared image from NASA's Spitzer Space Telescope shows the broken Comet 73P/Schwassman-Wachm ann 3 skimming along a trail of debris left during its multiple trips around the sun. The flame-like objects are the comet's fragments and their tails, while the dusty comet trail is the line bridging the fragments.
Dead Sea Scrolls will get their own database, courtesy of the web search giant. The Dead Sea Scrolls are some two thousand years old.
This false-color image shows the incredible, complex beauty of Saturn's rings. The massive ring system is over 150,000 miles in diameter.
