NASA has successfully completed the first stage of testing of lunar rovers that will be involved in the Artemis mission. They are designed to support astronauts in their work at the south pole of the Moon. The testing included 3 lunar rovers developed by commercial companies Intuitive Machines, Lunar Outpost and Venturi Astrolab. To create conditions simulating lunar gravity, the lunar rovers were tested in a special ARGOS system at NASA's Houston Test Center. During the tests, the reduced gravitational influence was reproduced. Astronauts in spacesuits performed various tasks, including using scientific instruments and interacting with the lunar rovers' control systems. Emergency drills were also conducted to test their ability to evacuate the crew in case of emergencies. The test results identified key aspects to improve the design of the lunar rovers. Next, the development teams will receive feedback from NASA, which will allow them to refine their models based on the data obtained
