Top 10 Sickening Facts About Space Travel

Space Travel Might Be Making Astronauts Infertile

There are speculations that long-term space missions are making astronauts infertile. In one experiment, male rats suspended above the floor during a six-week-long experiment, mimicking the weightlessness of outer space, suffered shrunken testes and severely low sperm count, which made them as good as being infertile. Female rats suffered a similar or even worse fate when they were sent into space. Their ovaries ceased working after just 15 days. By the time they returned to Earth, the gene responsible for producing estrogen (the female hormone) had become redundant, while the cells that produced eggs were dying.

Space travel has also been linked to loss of libido. In one experiment, two male and five female mice sent into space refused to mate. However, some researchers insist that space travel has nothing to do with libido or infertility. Fish and frog eggs sent into space have fertilized, though the frog offspring never developed past tadpoles. Male astronauts have also impregnated their wives days after returning to Earth.

Female astronauts aren’t left out. They have also gotten pregnant soon after returning from space missions, although they have a higher rate of miscarriage. The effects of space travel on reproduction remain debatable, and from the look of things, we’re not finding out soon. NASA has turned down attempts to get the sperm count of its male astronauts returning from space for privacy reasons.

Most Astronauts Get Space Sick

Despite advancements in space technology, space sickness remains one of NASA’s biggest headaches.More than half of all astronauts sent into space experience nausea, headache, vomiting, and general discomfort, which are all symptoms of space sickness, also called space adaptation syndrome. One notable astronaut who experienced space sickness is ex-senator Jake Garn, who started showing symptoms even before leaving Earth. By the time he returned, he couldn’t even walk properly.

Garn’s bout of space sickness was so terrible that his name became an informal measurement for the illness. Astronauts can rate their symptoms with phrases like like “one garn,” “two garns,” “three garns,” and so on. While NASA has yet to find a solution for space sickness, it has created an early warning device that lets astronauts know that they’re about to get space sick.

All Astronauts Wear Diapers

NASA had an oversight in designing the first space suit. Apparently, its scientists forgot that astronauts might need to pee while in their suits. This oversight caused astronaut Alan Shepard, the first American in space, to pee right inside his space suit. This only happened after series of deliberations because NASA scientists feared that the urine might short-circuit the electrical components of the suit.

To prevent similar scenarios during future missions, NASA came up with a condom-like device that astronauts wore while in their space suits. For obvious reasons, this device became a problem by the time women joined the space party in the 1970s, so NASA came up with a urine and fecal management system called the Disposable Absorption Containment Trunk (DACT). DACT was used by both sexes even though it was specifically made for women.

In 1988, NASA replaced DACT with the Maximum Absorbency Garment (MAG), which is basically an adult diaper, except that it has been modified to look like shorts. Each astronaut is given three MAGs for every mission. They wear one when going into space and one when returning and keep the third as an extra.
