Photos: Delta 4 launches on secret NROL-45 mission

Look back on the launch Saturday of a Northrop Grumman Antares rocket from Wallops Island, Virginia, powered by a pair of kerosene-fueled RD-181 engines producing 864,000 pounds of thrust.

Indian officials postponed the launch Sunday of the Chandrayaan 2 moon mission from a spaceport on the country’s southeastern coast with the Bay of Bengal. The robotic Chandrayaan 2 mission will lift off aboard the GSLV Mk.3, India’s most powerful rocket, but officials have not announced a new target launch date.

This detailed mission timeline covers major vehicle and crew activities during the Crew-2 countdown and rendezvous with the International Space Station.
