Orbital

In-Space Propellant Depots
In-space propellant resupply is a critical enabling technology for sustainable space exploration. Eta Space is developing propellant depots for orbital and lunar polar locations, with sizing for a variety of mission architectures. From Aerogel to Zero Boil Off, we develop and deploy advanced cryogenic systems critical to the future of space.

Cryo-Dock™
Introducing the world's first cryogenic propellant depot in orbit. Cryo-Dock™ is the first step in enabling sustainable space exploration by servicing spacecraft stages and orbital transfer vehicles with high-energy cryogenic propellants through a standardized, automatic umbilical.

LOXSAT
Funded by NASA, LOXSAT is a technology demonstration satellite that will test a series of cryogenic fluid management technologies in space, including zero-loss storage and transfer and cryogenic pressure control. Scheduled for launch in late 2024, LOXSAT will be stationed in Low Earth Orbit (LEO) for a total of 9 months. Upon proving these technologies in microgravity, LOXSAT will make way for Cryo-Dock™, a fully commercial cryogenic propellant depot in space.

Lunar

Local production of propellants and consumables will make Lunar and Mars exploration sustainable. Lunar propellant supply is critical for the development of reuseable Lunar landers, robust surface transportation, and life support systems. Eta Space is leading the development of these advanced Lunar cryogenic systems.

H2RENEW
Based on a proprietary electrochemical platform, SKYRE will electrolyse the ice water into its hydrogen and oxygen components and Eta Space H2RENEW™ will then compress and liquefy the hydrogen for use as fuel.

The H2RENEW is a solid-state system that requires little or no dependency on logistics to operate efficiently and has no moving parts which results in greater reliability and increased cost-efficiencies. It hits on all marks, making it the ideal fit for the demands of lunar liquefaction.

Two space tech companies, Helios and Eta Space, announce in 2022 that they are joining forces to solve the problem of oxygen in space. If humanity is to have a sustainable presence beyond Earth, the reusable methane-fueled rocket systems need liquid oxygen at a ratio of 1:4, so the only cost-effective solution to refueling in orbit is to create and store oxygen on the Moon and on Mars. "Eta Space would play the important role of liquifying and storing the oxygen produced by the Helios reactor in cryogenic tanks."

Lunar Propellant Production Plant (LPPP)
Using only the lunar polar resources including water and sunlight, oxygen and hydrogen propellants can be produced, liquefied, and stored for use in reusable lunar lander systems. Eventually these propellants can be exported to cis-Lunar space for use in the sustainable exploration of the solar system.

Lunar Oxygen Station (LOS)
Eta Space is developing a liquid oxygen refueling capability that can be deployed anywhere on the lunar surface. The Lunar Oxygen Station will be used to convert Lunar regolith into liquid oxygen for propulsion and life support applications.

In Situ Resource Utilization (ISRU)
From residual scavenging to resource prospecting to cryogenic liquefaction, Eta Space is working to enable the next phase of space exploration.
