Astra officials said Saturday a software fix will likely resolve a guidance system problem that caused the company’s first orbital-class rocket to begin drifting off course soon after liftoff from Alaska Friday night, prompting a range safety officer to terminate the mission.

China launched a Long March 2D rocket Saturday with a satellite Chinese officials claimed will study the space environment and conduct technology demonstrations, less than two days after a Long March 4B rocket took off from a different launch site with an Earth-imaging payload.

The liftoff of Europe’s first mission to Jupiter aboard an Ariane 5 rocket was scrubbed Thursday in French Guiana due to a high risk of lightning at the launch site, delaying until Friday the start of the JUICE spacecraft’s voyage of exploration.
