SpaceX is set to launch NASA's SPHEREx and PUNCH spacecraft on a Falcon 9 rocket from Vandenberg Space Force Base.The missions aim to maximize efficiency by flying two payloads at once, covering a broad range of NASA science.This launch signifies a shift in how NASA conducts its missions, embracing a rideshare strategy to enhance scientific returns.Future rideshare missions by SpaceX for NASA include IMAP and TRACERS missions scheduled for later in the year.Challenges delayed the launch, including environmental control system issues and pneumatic system leaks.The SPHEREx telescope will map the night sky in infrared over a two-year mission to study the origins of the universe and cosmic ices.The PUNCH mission, costing $150 million, features narrow field and wide field coronagraph and heliospheric imagers to study solar winds.The Falcon 9 first stage booster, supporting the launch of SPHEREx and PUNCH, will attempt its third landing at LZ-4.The launch readiness review was completed successfully, with live coverage starting about an hour before liftoff.The SPHEREx observatory aims to create a map of over 400 million galaxies and investigate the presence of water in the universe.
