SSO = Sun Synchronous Orbit LEO = Low Earth Orbit FTO = Failed to Orbit FSO = Failed Suborbital AD = Andoya Space Center, Norway KO - Kourou Space Center, French Guyana ------------------------------------------------------------------ ISAR AEROSPACE SPECTRUM LAUNCH VEHICLE Isar Aerospace, a German company, was founded in 2018, claiming to offer the "first fully privately funded European solution to meet the growing global demand for orbital launch. It developed Spectrum, a two-stage launch vehicle fueled by liquid propane (LPG) and liquid oxygen (LOX). Spectrum stands 28 meters and is 2 meters in diameter. Nine Aquila engines power its first stage. A single Aquila powers the second stage. Payload fairing options include 2.5 meter diameter variants that range up to 5.3 meters tall. Spectrum's initial launch site will be an Andoya Space Center in Norway, for sun synchronous missions. Future lower inclination launches are planned from Kourou.
