Video: Fourth X-37B launch highlights

A Japanese H-2A rocket, carrying the Michibiki 2 navigation satellite, lifted off from the Tanegashima Space Center at 0017:46 GMT Thursday (8:17:46 p.m. EDT Wednesday).

United Launch Alliance has released views from cameras mounted aboard the company’s most recent Atlas 5 rocket launch showing the rocket’s blastoff from Cape Canaveral at dawn Aug. 8 with a U.S. Air Force communications satellite.

The launch of NASA’s Mars 2020 rover is less than a year away, and the steady pace of work inside the craft’s pristine assembly hall in California is keeping the mission on schedule for liftoff from Cape Canaveral next July, despite growing costs, according to mission managers.
