Impulse Space is set to launch its Mira spacecraft aboard the Helios space tug, a cost-effective vehicle designed to transport payloads from low Earth orbit (LEO) to geostationary orbit (GEO), with support from the U.S. Space Force under a STRATFI contract.

The Mira spacecraft, based on Impulse's design, is integrated with the Helios kick-stage motor and Deneb engine for rapid insertion into GEO, and is scheduled for launch in late 2026 aboard a SpaceX Falcon 9 alongside another Mira for the Victus Surgo mission.

A key demonstration aims to showcase Mira's ability to autonomously analyze images and execute maneuvers for observation, addressing the U.S. Space Force's priority for tactical responsiveness in space operations.

The spacecraft will utilize a long-wave infrared (LWIR) sensor capable of detecting dim targets and operating effectively in low-light conditions, such as during eclipses or on the Earth's dark side, enhancing reconnaissance and persistence.

Impulse Space has partnered with Anduril Industries to develop a demonstration satellite for rendezvous and proximity operations (RPO), fulfilling increasing Space Force demand for autonomous maneuvering capabilities in space.

This joint project aims to demonstrate a maneuverable, high-thrust satellite in GEO, capable of orbital maneuvers and space domain awareness, with a targeted demonstration in 2026.

The collaboration emphasizes the development of a commercially funded satellite that can enable future U.S. Department of Defense missions involving rapid orbital maneuvering and strategic surveillance.

Anduril will supply payloads including LWIR imagers and data processors based on its Lattice software to enhance long-range target acquisition and on-orbit sensing.

Helios is promoted as a faster, lower-cost alternative to traditional GEO delivery methods, improving military response times to emerging threats or intelligence needs.

Once in GEO, Mira will detach from Helios to demonstrate autonomous approach, imaging, and maneuvering around targets, providing strategic monitoring and inspection capabilities.

This initiative aligns with broader efforts to develop maneuverable, autonomous spacecraft for rapid response and surveillance in GEO, which is critical for national security.

While the initial demonstration focuses on GEO, the design of Mira can be adapted for LEO missions with minimal modifications, mainly in radios and antennas.

The project supports the U.S. Space Force's push for improved space domain awareness and orbital warfare, emphasizing maneuvering satellites to counter threats from adversaries' satellite deployments.
