- The reference run reports 288.2069 kg of hydrogen used and 1211.7931 kg remaining after touchdown.
Field notes
The public architecture separates terminal descent, disturbance recovery, and active touchdown stabilization rather than presenting landing as a single headline metric. A reference run lists vertical touchdown speed, fuel consumption, remaining hydrogen, and a landing score, while a separate result reports 20 of 20 disturbance cases as safe. The site also states that controller logic, tuning parameters, geometry, and full test data remain outside the public view.
