For its scientific missions, NASA has tasked industry with developing an unpressurized — that is, open top — rover designed for two people by 2028.
Unlike the rovers of the Apollo missions, it would have to operate autonomously even without astronauts on board.
This means surviving the cold lunar nights, which can last up to two weeks, with temperatures dropping to around -280 degrees Fahrenheit (-170 Celsius).
Many companies have started.
Lockheed Martin has partnered with General Motors, relying on the auto giant’s expertise in electric and off-road vehicles.
Dynetics, a subsidiary of engineering behemoth Ledos, has joined forces with Nascar.
Its prototype, which will achieve a top speed of nine mph (15 kph), includes a robotic arm and metal wheels that hang like clothing to maximize traction on a sandy surface and tackle any rocks Has happened.
“But at the same time, they really have lots open to the outside so they’re not going to collect all that sand and take it with us,” Davis said.
Moon dust, or regolith, is a major challenge because, lacking erosion by water or wind, it is almost as abrasive as glass.
NASA has not yet announced the selected company or companies.
In the longer term, NASA is working with the Japanese space agency JAXA on a pressurized vehicle that would not require astronauts to keep their suits on.
