No one is sure, but there are some plausible ideas. She says one possibility is what happens to the fluids in your body in a weightless environment.
On Earth, gravity tends to drag those fluids downward, toward your feet. In space they go everywhere, including to your head, so after arriving in space, you begin to look like a cartoon character. Round, because they are retaining fluid in their heads. Perchonok has asked Hunter and her crew at Cornell to test the stuffy nose theory. To do that on Earth, volunteers will spend several weeks in a bed where their heads are lower than their feet to try to re-create that Charlie Brown effect.
As for the preference for hot peppers, one theory is that as the sense of smell is blocked, another starts to take its place: the heat of the peppers. Kimberly Binsted at the University of Hawaii, Manoa is trying to figure out what the best menu options are for people whose sense of smell is diminished.
And she is now recruiting participants for a Mars habitat simulation. Astronauts with the most sedate preferences at home ask NASA's Habitability and Environmental Factors Office -- the kitchen -- to pack foods that are hot-hot-hot. You get a lot of extra pressure, and it fills your sinuses, and the horseradish is a miracle worker for cleaning that out.
To make space food more interesting and probably generate some buzz while they're at it , NASA invited Rachael Ray to create some spaceworthy recipes; the selections favored by astronauts included spicy Thai chicken and vegetable curry.
Emeril Lagasse joined in too -- with green beans in hot sauce. What's been the most popular drink? Lemonade, because it's tart. Shuttle astronauts tend to request lemonade most often, because sweet drinks seem too sweet when you're weightless. For a flight, astronaut Mike Massimino made a case to get biscotti on his menu. They won't let us have pizza, so at least they gotta let us have biscotti. Mission managers were hesitant, worried about crumbs floating around the cabin imagine if one got in someone's eye.
They finally relented after Massimino arranged with a bakery for bite-size pieces. Some freeze-dried foods, like fruit, can be eaten dry. However, they have to attach themselves so they don't float around and bump into something. Space station crews usually sleep in sleeping bags located in small crew cabins. Each crew cabin is just big enough for one person. Generally, astronauts are scheduled for eight hours of sleep at the end of each mission day.
A: The ISS missions, called expeditions, usually last about six months. There are three to six crewmembers on board at all times. Professional astronaut crews come from the U. Military Astronaut Candidates are detailed to the Johnson Space Center and remain in an active duty status for pay, benefits, leave, and other similar military matters. Russian cosmonaut Valery Polyakov spent nearly consecutive days aboard the Mir space station, from January to March He therefore holds the record for longest single human spaceflight — and perhaps set another one for wobbliest legs when he finally touched down.
Using a chemical propulsion system, it took the Apollo astronauts about 2. The space shuttle uses a chemical propulsion system based upon both liquid and solid propellants. Gennady Padalka , who has spent days in space over 5 missions, became the man who spent the most time in space when he surpassed, on 28 June , the record of Sergei Krikalev who spent days, 9 hours and 39 minutes, or 2.
The longest consecutive spaceflight was done by Valeri Polyakov, who spent nearly days on the former Russian Mir space station. Spacecraft that have visited other planets. Earth's moon. Asteroid Eros.
