Kestrel Launch delays first orbital flight to Q3 after second-stage test anomaly

New Zealand-based smallsat launch company Kestrel Launch has slipped its first orbital flight from May to Q3 2026 after a second-stage ground test anomaly on March 29.

The delay

Kestrel Launch Ltd., a smallsat launch company based in Christchurch, New Zealand, announced on April 10, 2026 that its maiden orbital flight, previously targeted for May 17, 2026, has been rescheduled to no earlier than the third quarter of 2026. The company cited an anomaly during a March 29 second-stage static fire at its Māhia Peninsula test site.

The anomaly

The incident involved premature turbopump cavitation in the second stage's single Balaxa-class methalox engine approximately 42 seconds into a planned 180-second static fire. No injuries occurred and the engine was shut down safely by the automated abort system. Chief engineer Dr. Selene Okoye-Parata said the cause has been traced to a tolerance stack-up in the oxidizer inlet line and that revised hardware is in manufacture.

Vehicle and manifest

The Kestrel Alpha vehicle is a two-stage methalox rocket capable of 480 kg to a 500 km sun-synchronous orbit. The maiden flight — designated Mission 'First Light' — carries three commercial cubesat payloads and one University of Otago heliophysics experiment, all of which have accepted the schedule slip. Kestrel's launch-services manifest through 2027 currently lists eleven committed missions.

Financial impact

Kestrel confirmed the delay will push about NZ$14 million in anticipated 2026 launch revenue into the 2027 fiscal year. The company also announced it had drawn down NZ$22 million from a previously-unannounced NZ$40 million revolving credit facility with Westpac New Zealand to cover bridge costs during the manufacturing pause. The New Zealand Space Agency declined to comment on whether the delay affects Kestrel's launch licence renewal, scheduled for September 2026.
