The commanders of both space shuttle Discovery (STS-120) and the International Space Station (ISS), the two crewed spacecraft now in orbit, are women. So, this week in the interstellar media, headlines gush with a milestone in the annals of gender. "Women set to take charge of space," said...

At the veterinarian, they do it with an injection. When astronomers want to "put to sleep" one of their pets, they use a mouse click. Yesterday, astronomers at Johns Hopkins University shut down the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite after 8 years of service. The craft...

The Chang’e-1 lunar probe will explore the Moon from orbit. The mission includes mapping lunar topography, surveying the distribution of chemical elements, and gathering high-resolution photos of the lunar surface in preparation for future surface exploration. China National Space Administration I don't...

There I go again, nattering on about the dangers of spaceflight. Laugh if you will, but this is pretty interesting: Salmonella bacteria grown aboard the space shuttle turned out to be more harmful to its hosts — "virulent," for all the microbiology geeks out there. Salmonella is a leading cause...

This just in from the hydrocarbon desk at Astronomy.com: Titan’s surface lakes and methane-ice-laden dune seas collectively hold hundreds of times Earth’s bounty of hydrocarbons (oil and gas). It’s a Texas oilman’s dream: hydrocarbons rain from the sky on Titan. To my mind, this could solve a lot of...

NASA engineers have proposed a mission to an asteroid threatening Earth. Bruce Damer (DigitalSpace) I’m happy to report NASA may be planning to do more about the as-yet unaddressed asteroid threat to Earth than helplessly watch giant space rocks whiz by the home planet from time to time. The Guardian...

NASA’s lone gunmen say they have designed a better, safer, cheaper version of the Ares I crew launcher (above), one of the cornerstones of the post-Shuttle space program. NASA Remember the “ lone gunmen ,” the trio of militantly nonconformist Uber-geeks on The X-Files who tracked government conspiracies...

Last week , I told you we would show you a new map of Mercury based on the January MESSENGER flyby. Here it is, kindly provided by one of NASA’s master mappers, Robert Gaskell of the Planetary Science Institute in Altadena, California. This image is an anaglyph — a flat image that simulates a three-dimensional...

NASA head Michael Griffin has made some public comments recently expressing concern that retiring the shuttle program in 2010 will leave us utterly dependent on a foreign power (Russia) for access to the International Space Station. See Astronomy magazine's Executive Editor Dick McNally’s comments...

India’s lunar probe Chandrayaan-1 finally blasted off last night. Make that one more space-faring nation on its way back to the Moon. One of Astronomy magazine’s columnists, James Oberg, sent the information below out to the various media interests he writes for and agreed to let me share it with you...
