Astronauts underwater rehersal, HST repair mission

Rehearsal for the HST repair mission. Space-suited astronauts Kathy Thornton and Tom Akers seen during training for Shuttle Mission STS-61, the repair of the Hubble Space Telescope. To simulate working under zero gravity in orbit, the astronauts train inside a deep pool of water known as WET-F (Weightless Environment Training Facility). Here, the astronauts are practicing the removal of the telescope's Wide Field and Planetary Camera (WFPC), prior to inserting an updated version. At the bottom of the pool (out of frame) is a mock-up of the Shuttle's cargo bay area. STS-61 is scheduled for flight in December 1993

Non-magnetic iron sulphide

Demagnetisation of iron. Image 3 of 3. Iron sulphide being tested for magnetism with a bar magnet. The iron sulphide is not magnetic. Metallic iron is magnetic, and is attracted to a magnet. When iron is reacted with sulphur, as it has been here, the resulting compound does not retain the magnetism of the iron. See images A230/083-085 for a sequence showing the iron being demagnetised by a reaction with sulphur
