Part of the difficulty of studying asteroids is that they just won't keep still. NASA's current dawn mission to study Vesta, for instance, has taken eight years so far and cost $360 million even before it launched.

Russia identifies cause of space freighter failure

The recent disintegration of an ISS-bound space freighter was apparently caused by a malfunctioning gas generator located in the Soyuz carrier rocket's third stage engine.

Galaxy simulation mirrors Milky Way for first time

Astrophysicists have for the first time created a computer model of galaxy formation that results in a spiral galaxy like our own.

Miniature nuclear reactor designed for use on other planets

Engineers from NASA and the US Department of Energy (DOE) are working on a suitcase-sized nuclear reactor for use on the moon and other planets.

NASA: International Space Station could be evacuated

NASA is warning that astronauts may be forced to temporarily abandon the International Space Station (ISS) if a recent space freighter crash prevents Russia from ferrying a fresh crew to the station.

DARPA releases video of downed hypersonic plane

DARPA has released video footage of the Falcon HTV-2 flight earlier this month, which ended unceremoniously after just three minutes when it lost contact with the vehicle. And, guess what, DARPA says the flight was a great success.

The first robot member of the International Space Station crew woke up yesterday, six months after its arrival.

Fewer stars form as galaxies run out of gas

Galaxies are running out of the basic building blocks of stars. The universe is forming fewer stars than it used to, and an Australian research team says the reason is a shortage of molecular hydrogen.

Acoustic monitoring predicts dangerous solar flares

Predicting solar flares is going to become increasingly important as the sun hits the most active phase of its 11-year cycle.

Could microbes live in Martian brine?

A new million-dollar NASA project led by the University of Michigan aims to discover whether drops of salt water are common on Mars - and whether microbial life could survive in them.
