Definition of microgravity in English:



mass noun
  • Very weak gravity, as in an orbiting spacecraft.

    • ‘This uses a hybrid propulsion system, consisting of ducted fans, to move in microgravity and a differential traction system to move in normal gravity.’
    • ‘This research could provide swifter methods to acclimatising astronauts entering microgravity (as well as those returning to Earth).’
    • ‘But in microgravity, nothing is significantly ‘lighter’ than anything else, and such convection therefore plays no role.’
    • ‘It will investigate fluid physics in microgravity to understand how propellant-tank sloshing affects spacecraft control.’
    • ‘On the flip side, I do believe that if it is ever completed and fully crewed it will be producing significant amounts of first-class research in microgravity.’
    • ‘The first reason is purely scientific as new knowledge can be gained about the growth process in plants by growing them under microgravity.’
    • ‘Other physical sciences experiments are focused on subjects including foam and fire, both of which behave in very different ways in microgravity.’
    • ‘It's possible, however, since we're interested in pursuing the benefits of microgravity we haven't spent a great deal of time on this sort of thing.’
    • ‘Crystals formed in microgravity usually have a more perfect structure than those grown on Earth.’
    • ‘Each series will cover subjects such as satellite navigation, Earth observation, launchers, human spaceflight and microgravity, space science and astronauts.’
    • ‘Interior designs may therefore need to counter the natural disorientation that tends to occur in microgravity.’
    • ‘‘Philips has used parabolic flights once before to examine how halogen lamps function in microgravity,’ said Marco.’
    • ‘In microgravity and normal gravity, the period of the rhythm was longer when the animals were exposed to constant light than if they were kept in constant darkness.’
    • ‘To understand the effects of microgravity, researchers and medical doctors at ESA have developed innovative sensors to monitor astronauts' bodies as they live and work in space.’
    • ‘This, he explained, means large cabins with big windows, and an opportunity to float around the cabin during the four to five minutes' worth of microgravity during the flight.’
    • ‘For the first 73 seconds, he or she experiences microgravity at less than one percent of normal gravity.’
    • ‘In the suborbital flight regime, weightlessness or microgravity is not a significant issue.’
    • ‘Then, the effects of microgravity or weightlessness, and radiation on cabin occupants and some of the implications of these various factors will be discussed.’
    • ‘Crews endure loneliness, sensory deprivation, disorientating microgravity and the anxiety of knowing the vacuum of space is kept from them by an aluminium hull just a few millimetres thick.’
    • ‘A typical HTO suborbital concept might entail several minutes of microgravity.’
