The launch of a Japanese H-2B rocket was called off Tuesday after a fire broke out on the launch pad a few hours before liftoff. A new target launch date has not been confirmed. The mission will carry an HTV cargo ship into orbit on a resupply run to the International Space Station.

SpaceX will not be making a Falcon 9 launch attempt Tuesday night. The next opportunities to launch the Falcon 9 with 60 Starlink satellites from pad 39A at the Kennedy Space Center will come at 3:24 a.m. EST (0824 GMT) or 5:42 a.m. EST (0942 GMT) Thursday. This change in launch time suggests SpaceX will target a different orbital plane within the Starlink constellation.

On its second launch attempt after a propulsion problem prevented its light-class air-dropped rocket from reaching space last year, Virgin Orbit will try to deliver 10 experimental CubeSats into orbit as soon as Sunday on a mission booked by NASA five years ago for $4.7 million.
