zero gravity

Scientists working on behalf of NASA have successfully levitated a mouse using a strong magnetic field. I pay taxes so that stuff like this can happen. I don't hate animals. It's for understanding microgravity better, ok?

Not inclined to wait for a suborbital ride on Virgin Galactic, Noah Fulmor and Erin Finnegan became the firt couple to be wed in microgravity this past weekend over the skies of south Florida.

Doesn’t it seem that all movies and television shows suggest that space will one day be populated by nothing but dashingly lithe men and buxom women? Well there’s a reason it’s called science fiction, because extended space travel could actually leave astronauts a gross, bloated, unattractive mess. Astrobiologist Dr Lewis Dartnel projects that long-term exposure to zero gravity has the potential to ravage your looks in the most unappealing ways.

When humans eventually live on the moon and Mars, the discomforts of eating freeze-dried food and drinking our own urine will hardly be our only space nuisances. Apparently, our feet will tingle, we'll get headaches and toothaches, our eyes will be runny, and we'll have chronically stuffy noses.

Scientists have a pretty good notion of what will happen to your body when you're walking on the moon or traveling gravity-free for two years en route to Mars -- thanks to a cadre of bed-ridden test subjects.

Only six degrees separate you from zero gravity, or at least from its
thrilling physiological side effects. According to recent research,
lolling around for several weeks in a bed inclined six degrees—with
your head at the low end—mimics the muscle atrophy and bone
degeneration associated with spaceflight. This shortcut to zero
gravity may help researchers study the physiological implications of a
trip to Mars. Sure, muscle and bone loss isn't usually the highlight
of a trip to space, but a few weeks in bed is a lot cheaper than a
ticket on Virgin Galactic. —Eric Mika
