Astronauts report that their hands get cold while they are doing extravehicular activity, especially when they are not in sunlight. Two solutions were devised: fingertip heaters in their pressurized gloves and thermal mittens to wear over their gloves. This insulated mitten, designed by ILC, can add some warmth temporarily, but it would be removed for tasks that require finger dexterity. Astronauts tested mittens like this on the STS-63 space shuttle mission in 1995. Over the years, NASA gave the Museum a mitten pair and a variety of spacesuit gloves.
