It will come as news to many, no doubt, that there is a Warhol on the moon. And a Rauschenberg and an Oldenburg - a whole "Moon Museum," in fact, containing the work of six artists in all, in the form of drawings inscribed on the surface of a ceramic chip roughly the size of a thumbprint. Conceived by the artist Forrest Myers in 1969, the chip was fabricated in collaboration with scientists at Bell Laboratories and illicitly slipped by a willing engineer between some sheets of insulation on the Apollo 12 lander module.

Climate change from greenhouse gas emissions might threaten spacecraft as well as people, a scientists suggested on Sunday, providing direct evidence that carbon dioxide from human activity is affecting the outermost portion of the Earth's atmosphere. In a study published in the journal Nature Geoscience , a research team led by John Emmert of the U.S. Naval Research Laboratory's Space Science Division in Washington, described a new method for quantifying increases in carbon dioxide in the hard-to-measure portion of the upper atmosphere known as the thermosphere, which can't be reached by balloons and aircraft.

Outer space is about to get its first janitor satellite. Engineers from the Swiss Space Center at the Ecole Polytechnique Federale de Lausanne announced this week that they soon will begin work on CleanSpace One, a prototype for a line of brand-new satellites whose sole mission will be to remove defunct satellites from orbit. If the prototype is successful, the EPFL hopes to create a family of "de-orbiting" satellites so that humanity can practice in space what the Boy Scouts preach here on Earth - take only pictures (or data readings)

"Well, here it is," said aerospace engineer William Ailor as he paused next to the hulking metal shells arrayed along the plaza outside a visitors entrance at Aerospace Corp.'s El Segundo headquarters. The stuff is junk. But, Ailor said, it's no ordinary junk. This garbage has traveled to space and back. A 150-pound hollow sphere of blackened titanium is all that remains of a motor casing from a Delta II rocket that fell to Earth in 2001, landing in the Saudi Arabian desert west of Riyadh.

NASA gave the all-clear to the International Space Station, telling astronauts they would not need to steer away from a piece of satellite junk. Cape Canaveral experts had at one point believed that the debris might pass within a half-mile of the station today, just ahead of the shuttle Discovery's arrival. But as they studied the path of the small debris from an old Soviet satellite, engineers ascertained it would remain at a safe distance. A maneuver by the station would have forced Discovery to adjust its course for docking.

The collision of a U.S. commercial satellite and a derelict Russian military satellite generated an estimated tens of thousands of fragments that could threaten other satellites for 10,000 years, space experts said. Russian Mission Control chief Vladimir Solovyov said Tuesday's smashup poses serious danger to tracking and communications satellites in a popular orbit about 500 miles high, and that even tiny fragments are dangerous because they and the spacecraft travel at high speeds.
