Helios upper stage 3D model

Helios is a third-party upper stage/kick stage being developed by Impulse Space, as a launch vehicle add-on to enable higher payload capacity to high energy orbits. It is intended to support a range of existing and in-development rockets, including SpaceX's Falcon 9 and Starship, ULA's Vulcan, and Relativity's Terran-R. A single methane-oxygen Deneb main engine is used for main propulsion. From low Earth orbit, Helios can deliver up to five tons of payload to geosynchronous orbit. An ESPA-like adapter allows radial mounting of six small secondary payloads underneath a large primary payload, though other manifest options are available

Includes a notional interstage adapter

All textures and materials are packed into the .blend file, as well as a separate zip of textures. Instancing and modifiers have been used to reduce file size and allow easy editing
