NASA's Neil Gehrels Swift Observatory has officially ended its mission after more than 20 years, as it approaches a fiery reentry through Earth's atmosphere.

Then Nasa's Space Launch System rocket will launch from the Kennedy Space Center in Florida, carrying four Artemis III astronauts in the Orion capsule. This is the same type of rocket and spacecraft used for the Artemis II mission, which saw astronauts fly around the Moon and back to Earth.
