Under NASA’s Artemis II mission, four astronauts will take a 10-day journey around the Moon aboard Orion spacecraft. NASA’s Space Launch System (SLS), a 322-foot super heavy-lift rocket, will launch Orion which will serve as the crew’s command and living module. SLS can generate 8.8 million pounds of thrust, to escape Earth’s gravity and can reach speeds over 32,000 km/h.
