Live coverage: European mini-shuttle back on Earth

The launch of a Japanese H-2B rocket was called off Tuesday after a fire broke out on the launch pad a few hours before liftoff. A new target launch date has not been confirmed. The mission will carry an HTV cargo ship into orbit on a resupply run to the International Space Station.

Scientists culling through images taken last week by the Rosetta spacecraft’s sharp-eyed science camera have finally pinpointed the exact spot the Philae lander settled on comet 67P/Churyumov-Gerasimenko after a daring descent nearly two years ago, the European Space Agency announced Monday.

Europe’s next-generation launcher family has moved a step closer to reality with the signature of nearly $3.8 billion in contracts for development of the Ariane 6 rocket and an upgraded version of the lightweight Vega booster.
