A United Launch Alliance Delta II booster arrives at NASA's Building 836, the Spacecraft Labs Telemetry Station at Vandenberg Air Force Base in California. It will be offloaded and begin preliminary checkouts and preflight processing for launch of the agency's Ice, Cloud and land Elevation Satellite-2, or ICESat-2. Liftoff from Space Launch Complex-2 at Vandenberg is scheduled for Sept. 12, 2018, and will be the last for the venerable Delta II rocket. Once in orbit, the satellite is designed to measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. The satellite will carry a single instrument, the Advanced Topographic Laser Altimeter System. ICESat-2 will help scientists investigate why, and how much, Earth's frozen and icy areas are changing. These area make up Earth's the cryosphere.

Both halves of the United Launch Alliance (ULA) Delta II rocket payload fairing were moved inside ULA's Building B8337 at Vandenberg Air Force Base in California.

The LOFTID is dedicated to the memory of Bernard Kutter. LOFTID will demonstrate inflatable heat shield technology that could enable a variety of proposed NASA missions to destinations such as Mars, Venus, and Titan, as well as returning heavier payloads from low-Earth orbit.

Technicians work on installing ejectable data recorders onto NASA’s Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) inside Building 836 at Vandenberg Space Force Base in California on Aug. 19, 2022. Dedicated to the memory of Bernard Kutter, LOFTID is a technology demonstration mission aimed at validating inflatable heat shield technology for atmospheric re-entry. This technology could enable missions to other planetary bodies, as well as allow NASA to return heavier payloads from low-Earth orbit. LOFTID is a rideshare launching with the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite. NASA and NOAA are targeting Nov. 1, 2022, for the launch of JPSS-2 on a United Launch Alliance Atlas V rocket from Space Launch Complex-3 at Vandenberg.

Technicians assist as a crane lowers the payload adapter separation systems canister onto the Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) as part of launch preparations occurring inside Building 836 at Vandenberg Space Force Base (VSFB) in California on Sept. 9, 2022. LOFTID is the secondary payload on the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite mission. JPSS-2 is the third satellite in the Joint Polar Satellite System series. It is scheduled to lift off from VSFB on Nov. 1 from Space Launch Complex-3.

Technicians prepare to lift the Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) payload adapter separation systems canister, where it will go inside the payload adapter canister as part of launch preparations occurring inside Building 836 at Vandenberg Space Force Base (VSFB) in California on Sept. 1, 2022. LOFTID is the secondary payload on NASA and the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite mission.
