Photos: Liftoff of Atlas 5 from California

Lifting off in the predawn hours from India’s island spaceport, a Polar Satellite Launch Vehicle added a new navigation satellite to the country’s space-based positioning network this week.

A logistics-delivery vessel for the International Space Station, launched and operated privately by commercial companies on behalf of NASA, is scheduled to arrive at the lab complex Saturday at 6:05 a.m. EDT (1005 GMT).

Worsening weather at Rocket Lab’s New Zealand launch facility forced officials to call off the liftoff of a new commercial satellite booster for the third straight day Tuesday.
