ESA has lost a full-scale Space Rider landing-test model after an anomaly during deployment of its parafoil, the steerable parachute intended to guide the reusable vehicle to the ground. The agency confirmed the loss to European Spaceflight in a report published October 20, 2026. The test occurred earlier that month; an exact date has not been disclosed.
An independent investigation is examining the cause. ESA has not announced whether a replacement model is required or when testing will resume. European Spaceflight reports that the first orbital flight remains targeted for 2028, with the expected quarter moving from the first to the second.
How the Landing System Works
The model represented Space Rider’s final descent configuration. ESA’s April description identifies a 4.6-meter-long replica, built by Romania’s National Institute for Aerospace Research in Craiova and integrated at the Italian Aerospace Research Centre in Capua. The Italian center is responsible for designing and conducting the drop tests. Thales Alenia Space Italy leads the industrial test work and shares responsibility for the Space Rider program with Avio.
The parafoil measures 27 meters by 10 meters and supports a vehicle mass of approximately 2,950 kilograms. Onboard computers calculate the flight path, and two winches adjust the steering lines. This arrangement allows the system to respond to wind and guide the vehicle toward its landing point without a human pilot.
The test model’s landing gear remains deployed throughout the flight. The campaign consequently examines descent and landing behavior without also testing the gear-deployment mechanism. Packing and integrating the parachutes and parafoil took three weeks using specialized equipment.
The Test Campaign
Space Rider’s recovery system has progressed through different test configurations. ESA’s July 2025 account describes helicopter releases from altitudes reaching 2.5 kilometers, testing the parachute deployment sequence and autonomous guidance. Those trials used a mass simulator rather than the more representative vehicle configuration involved in the October loss.
A separate attempt in May 2026 was aborted during helicopter ascent, and the vehicle was recovered. The distinction matters to the test history: October involved a lost model after deployment trouble; May involved an interrupted attempt before the planned release.
Space Rider is designed to operate as an uncrewed orbital laboratory for approximately two months before returning experiments to Earth. Its combination of orbital operations and payload recovery places it among the reusable return systems covered in New Space Economy’s review of reentry vehicles. For this mission, the parafoil provides the controlled final approach needed to recover the laboratory on land.
The investigation will establish the cause of the deployment anomaly and inform ESA’s next test steps. Completing that landing qualification remains part of preparing Space Rider for its first orbital mission.
