In February 2021, orbiters from China and the UAE settled into their positions above Mars, and Nasa's Perseverance rover touched down on its surface. Maggie Aderin-Pocock reviews the astonishing footage the rover has already sent back, and talks with its legendary chief designer Adam Seltzer about the challenges of missions to the red planet.

Chris Lintott reveals the incredible 'track-and-trace' story behind the discovery of the Winchcombe Meteorite, and is given special access to the labs at the Natural History Museum to see the meteorite itself. Chris meets Dr Ashley King, who is co-ordinating UK-wide research into the rocky interloper, which it is hoped might tell us more about the early universe and reveal clues to the origin of life.

Pete Lawrence is on hand with a guide to viewing planets in the night sky, and to tell us what to look out for over the course of the rest of the year, and Maggie pays tribute to her childhood hero, Soviet cosmonaut Yuri Gagarin, who became the first person in space 60 years ago this month.
