The International Space Station (ISS) is set to land on Hawaii on Monday (July 31), with the first ever landing being scheduled for Saturday.
The mission is expected to take up to four hours, covering a distance of nearly 4,000 kilometres (2,500 miles) across the Pacific Ocean.
In order to avoid the usual weather problems associated with space launches, the ISS will not use a parachute or an oxygen mask.
Instead, the crew will use a special liquid oxygen supply and the spacecraft will use its parachutes, designed to avoid damaging the spacecraft’s internal structures.
There will be a series of small tests on the spacecraft before the landing, including docking and recovery of the lander, before the landers main job is done.
The ISS is not yet scheduled to return to Earth, and the crew and its equipment will remain in the station until its destination is determined.
