NASA officials plan to host a news conference at 2 p.m. EST (1900 GMT) Monday to update the status of the Perseverance rover’s mission on Mars. During the briefing, NASA is expected to release first-of-its-kind video captured by the mission during its descent to the Red Planet.

Mission managers will be closely monitoring the weather for the first launch of astronauts aboard SpaceX’s Crew Dragon spacecraft, not just around the Kennedy Space Center, but along a corridor stretching thousands of miles across the Atlantic Ocean in case the crew capsule has to escape from its Falcon 9 rocket during the climb into orbit.
