A Saturday night out, 260 miles above London

Watch live as ESA astronaut Tim Peake becomes the first British citizen to walk in space. He will step outside the International Space Station with fellow astronaut Tim Kopra to perform crucial repairs on the orbiting outpost’s electrical system.

Observers in the British Isles blessed with clear skies at dusk can see the 10-day-old waxing gibbous Moon pass in front of a naked-eye star known as kappa Virginis soon after 11pm BST tonight. Since the star disappears at the Moon’s darkened limb, it will be an easy target in most binoculars.

Next to the Moon and Venus, the International Space Station (ISS) can be the third brightest object in the nighttime sky. During the first ten days of August, the ISS is well placed for viewing before midnight for observers in the British Isles. We show you how, when and where to see it.
