Space traveler's eyesight can become blurry after too much time in space. [ 86 ] [ 87 ] Another effect is known as cosmic ray visual phenomena . [a] NASA survey of 300 male and female astronauts, about 23 percent of short-flight and 49 percent of long-flight astronauts said they had experienced problems with both near and distance vision during ...
dependence of risk on dose-rates in space related to the biology of DNA repair, cell regulation and tissue responses; predicting solar particle events (SPEs) extrapolation from experimental data to humans and between human populations; individual radiation sensitivity factors (genetic, epigenetic, dietary or "healthy worker" effects)
Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself , while others are injuries that could have occurred on Earth's surface.
Ever wonder what outer space smells like? After coming back from a spacewalk and pulling off their helmets, astronauts are hit with the scent of cosmic molecules that hitch a ride on their suits.
Whether there is life on Titan, the largest moon of Saturn, is currently an open question and a topic of scientific assessment and research. Titan is far colder than Earth, but of all the places in the Solar System, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes, and seas on its surface.
Humans are typically host to a hundred trillion microorganisms in ten thousand species in the human microbiome which cannot be removed while preserving the life of the human. Containment seems the only option, but effective containment to the same standard as a robotic rover appears difficult to achieve with present-day technology.
Studying the human-borne microorganisms is significant for human welfare and future crewed missions in space, whilst the extremophiles are vital for studying the physiological requirements of survival in space. [2] NASA has pointed out that normal adults have ten times as many microbial cells as human cells in their bodies. [3]
Levis says he and the production team were at the Titans' facility filming from 4 p.m. to midnight, trying to perfect the attitude of a not-at-all-joking fragrance commercial. "I take everything I ...
