NASA's Lunar Trailblazer sits on its rotation fixture after being fueled and prior to being installed to the EELV Secondary Payload Adapter (ESPA) ring at SpaceX's payload processing facility in NASA's Kennedy Space Center in Florida in early February 2025. The ESPA ring is an adaptor used for launching secondary payloads on launch vehicles. Figure A shows the spacecraft mounted horizontally, in its launch configuration, to the ESPA ring. The mission's two science instruments are visible. The High-resolution Volatiles and Minerals Moon Mapper (HVM³) is the angular structure atop the spacecraft; the Lunar Thermal Mapper (LTM) is the black square on the upper right of the front facing panel. https://photojournal.jpl.nasa.gov/catalog/PIA26460

Technicians integrate NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On Lagrange - 1 (SWFO-L1) satellite to the Evolved Expendable Launch Vehicle Secondary Payload Adapter Array Ring (ESPA) inside the Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida on Friday, Sept. 5, 2025. The integration of the rideshares prepares for the next milestone of attaching NASA’s IMAP (Interstellar Mapping and Acceleration Probe) Sun mapping observatory to a payload adapter and stacking all three observatories together to prepare them for encapsulation in the payload fairing.

Technicians integrate NASA’s four PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites to the evolved expendable launch vehicle secondary payload adapter array ring inside the Astrotech Space Operations Facility at Vandenberg Space Force Base in California on Friday, Feb. 14, 2025. PUNCH will study origins of the Sun’s outflow of material, or the solar wind, capturing continuous 3D images of the Sun’s corona and the solar wind’s journey into the solar system. The PUNCH mission is launching as a rideshare with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory scheduled to launch aboard a SpaceX Falcon 9 rocket at 10:09 p.m. EST (7:09 p.m. PST), Friday, Feb. 28, 2025, at Space Launch Complex 4 East from Vandenberg Space Force Base in California.
