Everyone is invited to attend a watch party at the Laboratory for Atmospheric and Space Physics (LASP) on Sunday, Sept. 21, when NASA’s MAVEN spacecraft, designed to understand past climate change on Mars, inserts itself into orbit after a 10-month journey to the planet. The event is free and open to the public, although seating will be limited. Doors will open at 6:30 p.m. The orbit insertion, expected to last 34 minutes, will begin at 7:50 p.m. and end at 8:24 p.m.
