HyImpulse - SL1

As of August 2023, HyImpulse Technologies has received the first Air Navigation Order from the UK Civil Aviation Authority (CAA) authorizing them to launch one rocket. The SR75, a large suborbital sounding rocket will launch from SaxaVord Spaceport no earlier than December 1st, 2023, and must occur before November 30th, 2024. HyImpulse is required to notify the CAA in writing atleast 14 working days prior to a planned launch date. 

We are developing an orbital small launcher, powered by our unique, green hybrid propulsion technology, delivering a higher performance at a fraction of the cost, with a higher operational safety and flexibility.

• ESA awards €1.5 million to three German launch startups, 2020-11-03.
• The In Orbit Aerospace re-entry capsule is scheduled to fly as part of the maiden flight on HyImpulse’s orbital vehicle, Small Launcher SL1 in 2024.
• The UK’s Civil Aviation Authority (CAA) has issued its first-ever Large Rocket Air Navigation Order Permit. The permit was issued to Germany’s HyImpulse Technologies as a general permission. HyImpulse must notify the CAA 14 days before launching a rocket. 2023-08-22.
  • The permit is valid for 1st December 2023 through 30th November 2024, and if they miss this deadline, the company will have to apply for the licence again. The vertical launch permit does clear the way for HyImpulse to launch from SaxaVord in the Shetland Islands.
  • The SR75 is a single stage craft that will carry out experiments in microgravity as well as the Earth’s atmosphere. HyImpulse describe it as “Europe’s first sounding rocket with a built-in house hybrid rocket motor that uses paraffin and liquid oxygen as its propellants.” It is capable of lifting up to 250kg in weight and recovering up to 700kg of mass with a parachute recovery system.
