It is important cause they will vomit
Using the Vomit Comet to experience moments of temporary weightlessness.
Astronaut candidates do "parabolic training" on a plane nicknamed the "Vomit Comet" (due to its tendency to induce motion sickness in passengers) so that they can experience weightlessness before being launched into space. If a potential astronauts is found to not be able to handle weightlessness, it's better to find that out before they actually get sent there for a long period of time. Also, weightless training gives them experience in how objects behave in zero-gee, so it's not a surprise when they get there.
The Modified B-707 (or K/C-135) used for low gravity training, (astronauts, etc.). It flew a paraboloic curve that simulated weightlessness.
Flying in a parabolic arc is the best we can do presently. Astronauts have to take such training aboard the "Vomit Comet"
because if you don't go to the vomit comit you will not know how to control your spaceship or your astraunatic devices and you have to know how to call or orbit another object because if anything goes wrong you need to contact another device to come help you
A "vomit comet" is an aeroplane that briefly achieves zero G, allowing people and prospective astronauts to experience weightlessness.In general, 65 seconds of flight will achieve 25 seconds of weightlessness.Weightlessness produces nausea and sickness (vomit) in two out of three people and thus the aeroplane earns it's nickname.Zero Gravity Corporation in the US, will allow you - for a fee (Probably including a cleaning change) - to experience this.See related link for more information
Some words that rhyme with "grommet" include "comet," "vomit," and "bonnet."
it is called vomit comet.
Here on Earth, we live in a gravity field that is one G, or "earth-normal gravity". We evolved here, and we expect this. In free-fall, there is no apparent gravity, no feeling of weight. (Gravity still affects everything, but if you aren't resisting gravity, you don't FEEL gravity.) Some people are prone to drop-sickness, and are prone to lose their lunches in free-fall. The parabolic flight path of the "Vomit comet" gives you a couple of minutes of free-fall, so that you can get used to the feeling.
They go underwater in a giant pool of water, it is the closest to 0 gravity on earth. Occasionally, they go into a plane called 'Vomit Comet'. The plane goes high up in the atmosphere and descends rapidly over a period of 30 seconds. The plane's descending speed hits the astronauts terminal velocity, hence the astronauts can simulate what it feels like to be weightless.

sometimes, if you feed your cat before it gives birth it will most likely vomit.
