One of the most significant challenges for any spacecraft is reentering Earth's atmosphere safely. The Space Rider spacecraft is no different, but recent tests have marked considerable progress. ESA engineers subjected the spacecraft's thermal protection system to extreme conditions, simulating the intense heat of atmospheric reentry. Using the largest plasma wind tunnel in the world at the Italian Aerospace Research Centre (CIRA), ESA exposed the spacecraft's components to temperatures reaching up to 2,900°F (1,600°C). This crucial test ensures that Space Rider can survive the fiery descent back to Earth.The thermal protection system also underwent tests to simulate how it would...
