Live coverage: Europe’s Mars mission launches

Researchers have found remnants of ancient ice sheets buried up to a mile below Mars’ northern polar cap, a record of seasonal climate change on the red planet.

Following in Curiosity’s footsteps, NASA’s Perseverance rover will attempt a daring high-speed descent to the surface of Mars on 21 February, depicted in an animation showing what flight controllers refer to as “seven minutes of terror.”

As avid skywatchers will already know, all of the bright naked-eye planets are currently visible in the pre-dawn sky — the first time in eleven years that such an alignment has occurred. At 6am GMT on Monday, 1 February, the last quarter Moon in the constellation Libra lies just 2½ degrees from magnitude +0.8 planet Mars low in the south for UK observers.
