Live coverage: H-2A rocket lifts off from Japan with navigation satellite

An automatic alarm in the final two minutes of the Delta 4-Heavy rocket’s countdown early Saturday forced officials to delay blastoff with NASA’s Parker Solar Probe by 24 hours.

NOAA’s new JPSS 1 weather satellite deployed from its Delta 2 launcher in an orbit more than 500 miles above Earth nearly one hour after blasting off from California.

SpaceX called off a launch attempt in Texas Monday for the Super Heavy booster and Starship launch vehicle, blaming a bad valve on the first stage. The next launch attempt for the world’s largest rocket is scheduled for Thursday, depending on weather and a fix for the valve problem.
