Electron | LOXSAT 1

LOXSAT 1 is a demonstration satellite of a complete cryogenic oxygen fluid management system in orbit, developed by Eta Space and sponsored by NASA's Tipping Point program. The system will be integrated on a Rocket Lab Photon-LEO satellite bus and collect critical cryogenic fluid management data in orbit for 9 months, demonstrating capabilities of in-space cryogenic storage and transferal. Eta Space plans to use technology developed for this mission to develop a truly commercial depot intended to serve multiple customers in the future.

This mission is flown by Rocket Lab. It is classified as a technology mission. Liftoff is planned from Unknown Pad. Launch windows shift often; this page is rebuilt every day with the latest scheduled time.
