InSpacePropulsion Technologies

ISPTech, short for InSpacePropulsion Technologies GmbH, makes propulsion systems for spacecraft. It is based in Ludwigsburg, Germany. The site says its solutions cover spacecraft from CubeSats to SmallSats and larger satellites.

HyNOx is the company's propulsion line for CubeSats to SmallSats. The site says it uses easy-to-handle propellants and offers thrust levels from 1 N to 200 N. HIP_11 is for larger satellites and spacecraft. It is a hypergolic propellant combination that the site says offers similar performance to conventional hypergolic propellants, with higher density and lower hazards. Its thrust levels start at 22 N.

The site says the thrusters are based on years of research at the DLR Institute of Space Propulsion, including thousands of hot firings under air and vacuum conditions. It says the company uses non-toxic propellants, standard parts and additive manufacturing to reduce cost, and that its production and testing processes allow rapid delivery.

The news section includes several milestones. In September 2025, the HIP_11 22N thruster reached Technology Readiness Level 5 after vacuum testing with DLR, and the HyNOx 4U CubeSat module entered flight configuration. In February 2026, the company announced a 5.5 million euro seed round. In October 2024, The Exploration Company signed a licence to use HIP_11 in its Nyx capsule.

The site says the team has more than 40 years of combined experience in space propulsion. It says the company moved into a new headquarters in Ludwigsburg Industriezentrum in April 2025 to support team growth, testing and production.
