Since dust can not settle in zero gravity, small pieces of dead skin or metal can get in the eye, causing irritation and increasing the risk of infection. [88] Long spaceflights can also alter a space traveler's eye movements (particularly the vestibulo-ocular reflex). [89]
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
When the space suit is removed on return to the spacecraft, there will be the potential for the dust to contaminate surfaces and increase the risks of inhalation and skin exposure. Astronautical hygienists are testing materials with reduced dust retention times and the potential to control the dust exposure risks during planetary exploration.
Space heaters also have a hidden hazard: They can cause overheating — aka hyperthermia — especially in kids, people with disabilities and older adults who may have difficulty leaving a room ...
Researchers are learning more about the way space travel affects the body. According to a recently published study on mice, microgravity may have been to blame for the thinning of their skin and ...
There was no warning label, no recommended dosage — only the words "Space Dust," the product's name, scrawled in black marker across an otherwise blank bag. What to know: Kratom becomes the ...
NASA Marshall Space Flight Center is leading a research effort to develop a Miniaturized Variable Pressure Scanning Electron Microscope (MVP-SEM) for future lunar and Martian missions. [ 76 ] Several teams, including Jonathan Rothberg, and J. Craig Venter, are separately developing solutions for sequencing alien DNA directly on the Martian ...
International Space Station image taken on September 11, 2001, with the smoke plume rising from Lower Manhattan and extending over Brooklyn (Expedition 3 crew). Within seconds of the collapse of the World Trade Center in the September 11 attacks, building materials, electronic equipment, and furniture were pulverized and spread over the area of the Financial District of Lower Manhattan.
