Impulse Space operates two vehicle programs, Mira and Helios.
Helios requires higher-thrust chemical propulsion, larger propellant tanks, and thermal management hardware that Mira does not need.
Helios is a kick stage designed for geosynchronous orbit rideshare and deep-space transfer.
As of June 2026, Helios has not flown.
The first flight of the Helios kick stage is Impulse Space's next scheduled milestone in 2027.
Impulse Space's Helios kick stage is scheduled for first flight in 2027.
Helios is designed to move payloads from low Earth orbit to medium Earth orbit, geostationary orbit, heliocentric trajectories, and lunar destinations.
Impulse Space operates the Helios kick stage for geosynchronous orbit rideshare and deep-space transfer.
Helios is a high-energy kick stage designed to deliver payloads to distant orbits faster and more affordably than traditional methods.
Impulse Space is preparing to launch Helios in 2027.
Project Helios is designed to bridge laboratory materials development and field system applications for hypersonic materials.
Project Helios is intended to expand the United States’ aero-thermal test capacity to support growing defense needs.
The Odon site selection is a milestone for Kratos’ Project Helios.
Kratos previously won the contract to design and build the new Project Helios test facility.
Selene and Helios are two Greek CubeSats managed by EMTech Space and carrying CubeCAT laser terminals for satellite optical connectivity testing.
Exolaunch deployed satellites for the Hellenic Space Center to support Greece’s space capabilities with the HELIOS and SELENE satellites.
SES is the first commercial customer for Impulse Space’s Helios kick stage mission.
Kratos received a $68.3 million award in October 2025 for Project Helios to construct a mid-tier arc jet and fiber laser facility.
Helios scheduled Beta Phase 1 through April 2026 to optimize UI/UX and strengthen data search and viewing functions and scheduled Phase 2 from May 2026 to test advanced multimodal analysis and LLM-agent automation.
Helios (Kabushiki Kaisha Helios) of Sumida-ku, Tokyo, led by Kyōhei Yashima and Kenichi Sasaki, began offering a beta version of the geospatial analysis platform Helios Platform on February 2, 2026.
