NASA are trying to arrange a manned mission to Mercury even although most scientists say that life could not survive on the planet because of the lack of oxygen and the intense heat.
Mercury is the closest planet to the sun and if you could stand on the surface our sun would appear two and a half times bigger in the sky.
Paul Scott a scientist who has been working with NASA has invented a special spacesuit which will keep the astronaut cool and protect the eyes from the intense heat and light.
The surface of Mercury is a cratered surface very much like the moon so it would be worth a visit to take rock samples and bring them back to earth.
