The agency gave a rosy update on Artemis III, a test flight for its goal to return humans to the moon, but experts say the timeline is ambitious.

NASA has chosen four astronauts for the Artemis III mission, but there has been a major setback: the destruction of a Blue Origin rocket and its only launchpad. Our science reporter Katrina Miller describes what this event might mean for the U.S. goal of landing on the moon by 2028.

A Nasa espera que 2028 seja o ano de um pouso tripulado na Lua, uma ambição que reflete o objetivo de Donald Trump de levar a humanidade de volta à superfície lunar antes do fim de seu segundo mandato.

Artemis III is the third in a series of missions that gets humans closer to returning to the surface of the moon.
