Engineers worked Thursday to figure out why one of two cooling pumps aboard the International Space Station malfunctioned. If the problem is hardware-related, astronauts will need to retrieve a spare pump – via a spacewalk.
Researchers are enhancing a dense network of GPS receivers with temperature, air-pressure, and motion sensors common in today's smart phones. The prototype promises precious minutes of advance warning for extreme weather, tsunamis, and earthquakes.
The huge orbit of a Jupiter-like gas giant has researchers scratching their heads over how the thing could ever form so far from the nearest star and the star's accompanying debris disk. But they've got some intriguing theories.
