NASA's Space Launch System rocket is set to launch for Artemis II, a mission that will take us closer to the moon than we've been in over a century. The launch will take Orion spacecraft and four astronauts, with concerns about potential issues with clouds near the launch site. The mission will be completed by NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen. If successful, this will be a significant step towards astronauts actually landing on the lunar surface. If all goes well, NASA could be ready for a landing with either Artemis IV or Artemis V within the decade.
