The four astronauts who left Earth on Monday have arrived at the International Space Station (ISS).
Their SpaceX Dragon capsule made a series of inch-perfect manoeuvres to bring them into an attachment position on the front of the orbiting lab.
Commander Mike Hopkins, Shannon Walker, Victor Glover and Soichi Noguchi will be spending the next six months aloft.
They join three individuals already aboard – Kate Rubins, Sergey Ryzhikov and Sergey Kud-Sverchkov.
Raising the resident complement to seven individuals will triple the amount of microgravity science that can be conducted on the 410km-high outpost, the US space agency Nasa says.
