Orion is NASA's next-generation spacecraft, and its goal is to take humans deeper into space than ever before with the ultimate goal of a mission to Mars in the 2030s.To achieve that, Orion needs to be able to reach very high speeds and withstand extreme temperatures and radiation levels. Orion's first test flight saw no astronauts on board but loaded with nearly 1,200 sensors to measure every aspect of the mission. That will allow NASA to assess whether the journey would have been suitable for astronauts.
