Video: Liftoff of Atlas 5 rocket with Mexico’s Morelos 3

In the first official weather outlook the planned launch this week of NASA’s Mars 2020 Perseverance rover, meteorologists predict an 80 percent chance of favorable conditions to allow liftoff of an Atlas 5 rocket from Cape Canaveral Thursday.

The additional docked time will give Starliner commander Barry “Butch” Wilmore and co-pilot Sunita Williams more time to help out aboard the station while flight controllers and engineers continue scrutinizing telemetry and finalizing plans for re-entry with five known helium leaks in the capsule’s propulsion system and unexpected, presumably now-resolved issues with multiple maneuvering jets.

Rocket Lab’s seventh and final launch of the year delivered a small radar observation satellite into orbit for Synspective, a Japanese startup planning a fleet of 30 or more Earth-imaging spacecraft providing day-and-night imagery of cities around the world.
