Haven Demo

Overview

A 552 kg testbed satellite that flew Haven-1's non-human-rated systems in orbit before the station's launch. Launched November 2, 2025 on SpaceX's Bandwagon-4 rideshare to a 510 km orbit, it completed 49 test objectives — validating GNC, avionics, power, solar arrays, thermal control, propulsion, RF communications, and radiation mitigation — and ended with a controlled deorbit burn on February 4, 2026.
