Live coverage: ExoMars orbiter safely arrives at Mars, lander’s fate uncertain

Observers in the British Isles with a clear sky one hour after sunset on 24 August should find a location that offers an unobstructed view of the south-southwest horizon. Here you will see first-magnitude star Antares in the constellation Scorpius, Mars and Saturn all in a line easily encompassed by low-power binoculars in the bright twilight.

The drill at the end of the Curiosity Mars rover’s robot arm is back in action after being sidelined for more than a year by a mechanical problem. A new technique was successfully tested 20 May after months of engineering tests on Earth.

A young massive star that began life around 25 times more massive than our own Sun is shedding shells of material and fast winds to create this dynamic scene captured by ESA’s XMM-Newton.
