30 years ago... Last EVA Omega "Alaska III" Speedmaster September 1993, after a decade of spacewalk usage of the 4750 spacesuit glove series with sewn-in integrated Omega Speedmaster in the righthand glove, NASA started to use the Phase VI series gloves and NASA astronauts no longer wore a Speedmaster during EVA - spacewalks! During the 6th spaceshuttle flight, the 1st for "Challenger", NASA astronauts performed the first EVA - spacewalk wearing an Omega Speedmaster since the Skylab days of 1974! On this 4 hours long EVA, both Story Musgrave and Donald Peterson wore an Omega Alaska III "Radial Dial" Speedmaster chronograph, which was sewn-in the outer layer of their righthand spacesuit glove. This kind of spacesuit gloves was used for ten years, up to STS-51 “Discovery” in September 1993. From then on, NASA astronauts didn't wear the Speedmaster any longer for EVAs, but the Russian cosmonauts did, strapped over their Orlan spacesuits until 2022. Overall, the radial dial Speedmaster was worn in space between November 1981 (STS-2) and October 1995 (STS-73). Photos show NASA astronaut Story Musgrave in the cargo bay of orbiter “Challenger” wearing the EMU - Extravehicular Mobility Unit, with the Speedmaster sewn-in the extra pocket of the righthand glove’s outer TMG - Thermal Micrometeor Garment layer.
