Our take
Impulse Space is developing a line of orbital transfer vehicles (OTVs) that enhance satellite manoeuvrability in space. The company offers products like Mira, for last-mile satellite deliveries and Helios, which can move spacecraft from low Earth orbit to geosynchronous orbit in under 24 hours. Recognizing the strategic value of manoeuvrable spacecraft, the US Space Force awarded Impulse a $34.5M contract for two missions set for 2026. These missions, Victus Surgo and Victus Salo, will demonstrate in-space operations and enhance space domain awareness, showcasing the Space Force's focus on quickly responding to threats in a congested space environment. Alongside this, the company secured substantial funding that will allow it to expand its operations and advance its OTV technology. With a proven track record of successful missions and strategic partnerships with the Department of Defense, Impulse is well-positioned to lead in the growing market for responsive satellite services.
