The team, including Sierra Nevada Corp., Maxar Technologies, Oceaneering and Paragon Space Development, delivered its Option A HLS proposal to NASA after conducting a 10-month continuation review, Dynetics said Wednesday.
Dynetics noted that it informed NASA of the landing systemâ€™s software and hardware components as well as mission plans, early design strategy and testing operations.
During the assessment, the team worked to address mission-specific concerns such as the interaction between lunar regolith and spacecraft engines, cabin airflow and air revitalization system design. Dynetics also tested the lander's reaction control system engines to study their capacity to operate in flight-like conditions.
Kim Doering, vice president of space systems at Dynetics, said the teamâ€™s technical data is meant to lay â€œa solid foundationâ€ for sustainable and crew-centric human flights to the lunar surface.
Previously, Charles Stark Draper Laboratory provided a simulator to support initial human-in-the-loop testing of Dyneticsâ€™ HLS guidance technology, control software and navigation system.
Dynetics is continuing simultaneous assessments of the HLS engines at the companyâ€™s propulsion test facility andÂ NASA's Marshall Space Flight Center in Huntsville, Alabama.
