Live coverage: H-2A rocket blasts off with latest Japanese weather satellite

SpaceX launched a Falcon 9 rocket at 8:51 a.m. EST (1351 GMT) Sunday from Cape Canaveral with the first in a new line of upgraded U.S. Air Force GPS navigation satellites. The launch was delayed five days due to technical and weather concerns.

SpaceX rolled out a Falcon 9 rocket to launch pad 39A early Tuesday for a prelaunch hotfire test before this weekend’s liftoff with a classified payload for the National Reconnaissance Office, the U.S. government spy satellite agency. The static fire test was completed at 3:02 p.m. (1902 GMT).

Japanese officials halted a countdown Monday at the Tanegashima Space Center when teams overseeing preparations for launch of an H-2A rocket detected a nitrogen gas leak, prompting the return of the launcher and its Japanese government payload to a nearby assembly building for repairs.
