SpaceX’s next two missions will revert to launching older versions of the company’s Starlink internet satellites, instead of new second-generation Starlink platforms as originally planned, while ground teams work out unspecified problems with the first batch of upgraded Starlinks launched in February.

DigitalGlobe’s WorldView 4 commercial Earth observation satellite, which launched in 2016 for a planned 10-to-12-year mission, has suffered a failure in its control moment gyros and is no longer able to acquire high-resolution imagery, officials announced Monday.

Most parts of the joint European-Russian ExoMars lander and rover are nearly ready for launch, but trouble with parachutes, electronics, software and concerns about the growing coronavirus pandemic have delayed the mission’s departure to Mars from this year until 2022, officials announced Thursday.
