Inside SpaceX’s Payload Processing Facility at Vandenberg Space Force Base in California, both halves of the Falcon 9 rocket’s protective payload fairing move toward NASA’s Double Asteroid Redirection Test (DART) spacecraft on Nov. 16, 2021. The payload fairing, with the spacecraft securely inside, will be attached to the top of the Falcon 9 and will protect the spacecraft during launch and ascent. DART is the first mission to test technologies for preventing an impact of Earth by a hazardous asteroid. The mission is scheduled to launch no earlier than 1:21 a.m. EST Wednesday, Nov. 24 (10:21 p.m. PST Tuesday, Nov. 23), from Vandenberg’s Space Launch Complex 41. NASA's Launch Services Program based at Kennedy Space Center in Florida, America's multi-user spaceport, is managing the launch.

Technicians reintegrate the Solar Wind and Pickup Ions (SWAPI) instrument of NASA’s IMAP (Interstellar Mapping and Acceleration Probe) observatory inside the high bay at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Monday, June 23, 2025. As IMAP spins in space, solar wind particles are swept into SWAPI through a special opening called “sunglasses,” an opening covered by a screen with very tiny precise holes that cut down the brightness of the very intense solar wind. SWAPI collects and counts particles from the solar wind flowing from the Sun and particles called pick-up ions that have entered the heliosphere from outside the solar system and traveled inwards where IMAP orbits near Earth. Launch of the IMAP mission is targeted for no earlier than September 2025 aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy.
