Name: How do you weigh yourself in space? Category: Space Date Added: 21 September 2014 - 08:24 AM Submitter: FizziksGuy Short Description: None Provided The International Space Station carries a body mass measurement device, similar in principle to that used on Skylab, for weighing cosmonauts. The cosmonaut places chest and abdomen on the subject support and footrests and handlebars immobilise feet and hands. A thumb-activated lever unlocks the unit to begin oscillations - the frequency of vibration measures the mass of the subject to 0.5% accuracy. View Video
