An update is coming today on NASA's Artemis 2 lunar mission to launch four astronauts on a historic journey around the moon.

A 1,300-pound NASA satellite will crash back to Earth in an expected milestone that will bring to an end its 14 years of orbiting our planet.

An old NASA science satellite plunged uncontrolled from orbit and reentered over the Pacific on Wednesday.

Early analyses predict the 1,323-pound (600-kilogram) vehicle will strike the atmosphere around 7:45 p.m. ET Tuesday, “with an uncertainty of +/- 24 hours,” according to NASA and the US Space Force.
