Mars Rover Spirit Unearths Surprise Evidence Of We

admin 发表于 2007, May 22, 11:21 AM

A patch of Martian soil analyzed by NASA's rover Spirit is so rich in silica that it may provide some of the strongest evidence yet that ancient Mars was much wetter than it is now. The processes that could have produced such a concentrated deposit of silica require the presence of water. Members of the rover science team heard from a colleague during a recent teleconference that the alpha particle X-ray spectrometer, a chemical analyzer at the end of Spirit's arm, had measured a composition of about 90 percent pure silica for this soil.

Oresme Crater Show Many Signs Of The Early Lunar H

admin 发表于 2007, May 22, 11:21 AM

This image, taken by the Advanced Moon Imaging Experiment (AMIE) on board ESA's SMART-1 spacecraft, shows the Oresme crater on the Moon. AMIE obtained this picture on 30 August 2006 - only 4 days before SMART-1's final impact on the lunar surface. It was taken from a distance of 1 100 kilometres over the surface, with a ground resolution of 110 metres per pixel.

China was "losing no time" in preparing its first lunar orbiter, Chang'e I, which will most likely be launched in the second half of 2007, a space official said here on Sunday. "The moon probe project is the third milestone in China's space technology after satellite and manned spacecraft projects, and a first step for us in exploring deep space," said Sun Laiyan, chief of the China National Space Administration.

Creating the Conditions Inside Supergiant Planets

admin 发表于 2007, May 21, 7:58 AM

We won’t be visiting a supergiant planet any time soon. But physicists are about to do the next best thing, and creat the conditions that exist inside the most dense planets right here on Earth. What used to require a nuclear explosion should now be possible with diamond anvils and powerful lasers.

Researchers from the Lawrence Livermore National Laboratory (LLNL), New Mexico State University and France’s Atomic Energy Commission announced this week that they have achieved pressures of 10 million atmospheres using a 30 kilojoule ultraviolet laser. The next step will be to use a 2 megajoule laser to achieve more than a billion atmospheres of pressure. Just for comparison, the centre of the Earth squeezes with a little less than 4 to 5 million atmospheres, and the centre of Jupiter is 70 million atmospheres.

Book Review: Pluto and Beyond

admin 发表于 2007, May 21, 7:56 AM

Great riches can buy you a yacht, a mansion or even an observatory. Percival Lowell went for the later and thus, still today, there is the privately owned Lowell Observatory. This facility forms the basis for the topics in Anne Minard’s book, Pluto and Beyond – A Story of Discovery, Adversity, and Ongoing Exploration. Many stories within cover interesting personalities, advances in astronomy and thoughts on the future.

Spitzer Shows Young Stars Hatching in Orion

admin 发表于 2007, May 21, 7:56 AM

The latest image released from the Spitzer Space Telescope shows infant stars “hatching” in the head of Orion. Astronomers think that a supernova 3 million years ago sent shockwaves through the region, collapsing clouds of gas and dust, and beginning a new generation of star formation.
