After nine months in space, Nasa astronauts Butch Wilmore and Suni Williams have finally arrived back on Earth. Their stay on the International Space Station (ISS) was only supposed to last eight days, but their mission was dramatically extended after the spacecraft that they arrived on, called ‘Starliner’, began to have technical problems.

NASA astronauts Sunita Williams and Barry “Butch” Wilmore splashed down safely Tuesday in the Gulf of Mexico after an extended stay aboard the International Space Station.

NASA astronauts are returning to Earth after nine months in space. Experts have said a prolonged period in space can come with changes to human physiology and psychology.
