A powerful European Ariane 5 rocket blasted off from French Guiana late Friday and boosted a pair of satellites into space for a seven-year plunge into the inner solar system, a voyage requiring seven planetary flybys to slow down enough in the sun’s gravitational clutches to slip into orbit around hellish Mercury.

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. 

Concerns over an unspecified part flying on the upper stages of United Launch Alliance’s rockets have delayed the launch of a GPS satellite on a Delta 4 booster from July 25 to no earlier than Aug. 22. The same issue has also delayed an Atlas 5 launch.
