Glitch makes NASA cut short Endeavour spacewalk
NASA managers cut short a task on Friday's otherwise routine spacewalk by two Endeavour astronauts because one of their carbon dioxide sensors stopped working, but most of their work was already finished.
The antenna in the valley
When Galileo Galilei turned his modest spy glass towards the stars in the summer of 1609, he opened up new skies. He observed things which no one had ever seen before: mountains and craters on ...
Voyager, the love story
