Briefing

What Hype is tracking

Construction completion and entry into final testing signal the program is transitioning from assembly to launch readiness, with a scheduled 2027 launch date.
Final environmental campaigns follow recent successful acoustic, vibration and thermal‑vacuum test sequences completed on Roman’s spacecraft elements (acoustic, vibration and thermal‑vacuum testing).
Late‑stage program support remains in focus after congressional attention to proposed Goddard facility changes that could affect mission work (requests to pause lab closures at Goddard).
