Persevering through a global pandemic, a last-minute earthquake, and the trials of a rocket launch, NASA’s next Mars rover — named Perseverance — took off from Cape Canaveral Thursday on a nearly seven-month journey to the Red Planet with sophisticated science instruments, technology to collect samples for to Earth, and the first interplanetary helicopter that could produce a “Wright Brothers moment” on another world.

A technical issue with the United Launch Alliance Atlas 5 rocket that will send NASA’s $2.4 billion Perseverance rover toward Mars has pushed the mission’s launch date back to no earlier than July 30, nearly two weeks into a month-long window for the rover to head to the Red Planet, or else face a two-year delay.

SpaceX performed a hold-down test-firing Jan. 20 of a Falcon 9 rocket at Cape Canaveral in preparation for a launch with 60 Starlink broadband satellites, but officials delayed the missions’s planned launch Tuesday due to extreme weather in the downrange recovery zone for the first stage and payload fairing. The next possible launch attempt is expected at 9:49 a.m. EST (1449 GMT) Monday.
