German launch startup HyImpulse has rescheduled the second flight of its SR75 suborbital rocket to spring 2027. The company previously targeted a launch for the end of 2026. The delay is attributed to the remaining regulatory requirements and seasonal weather conditions at the SaxaVord Spaceport in Scotland, rather than technical issues with the vehicle itself.
On 1 October, HyImpulse received a launch operator licence from the UK Civil Aviation Authority. This permit allows one SR75 flight per 12-month period. Before the launch can proceed, the company must fulfill conditions regarding insurance, hazard-area arrangements, and data-sharing with the National Space Operations Centre. Some documentation is required 60 days before the launch window.
Preparations for an earlier launch window between 5 October and 18 October did not meet the necessary requirements, leading to the postponement. The upcoming mission from SaxaVord will mark the first time the SR75 carries commercial payloads. The rocket utilizes a paraffin-and-liquid-oxygen hybrid propulsion system, which is also intended for the company's future SL1 orbital launcher.
HyImpulse conducted its first test flight of the SR75 rocket on 3 May 2024. This initial mission took place at the Koonibba Test Range located in South Australia. The company is now focusing on meeting the regulatory framework set by the UK authorities to ensure the launch can proceed from European soil in 2027.
