The Orion class refers to a series of spacecraft designed for deep space exploration, primarily developed by NASA. These spacecraft are intended to carry astronauts beyond low Earth orbit, with missions planned for destinations like the Moon and Mars. The Orion class features advanced life support systems and enhanced safety measures to protect crew members during long-duration missions. The first spacecraft in the Orion class, known as Orion Multi-Purpose Crew Vehicle (MPCV), was designed to support various missions, including those under the Artemis program. This program aims to return humans to the Moon and eventually send them to Mars. The Orion class represents a significant step in human space exploration capabilities.
