Space medicine is a developing medical practice that studies the health of astronauts living in outer space. The main purpose of this academic pursuit is to discover how well and for how long people can survive the extreme conditions in space, and how fast they can re-adapt to the Earth's environment after returning from space.
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 ]
By definition, these clouds must have a v lsr greater than 90 km s −1, where v lsr is the local standard rest velocity. They are detected primarily in the 21 cm line of neutral hydrogen, [6] and typically have a lower portion of heavy elements than is normal for interstellar clouds in the Milky Way.
Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
The crew found it to be better than that of Apollo but still unsatisfying, partially due to food tasting different in space than on Earth. [37]: 292–293, 308 The frozen foods were the most popular, and they enjoyed spicy foods [38]: 130 due to sinus congestion from weightlessness dulling their senses of taste and smell.

In October 2020, astronomers reported a significant unexpected increase in density in the space beyond the Solar System as detected by the Voyager 1 and Voyager 2 space probes. According to the researchers, this implies that "the density gradient is a large-scale feature of the VLISM (very local interstellar medium) in the general direction of ...
On Wednesday, Aug. 7, the agency held a news conference giving an update on the two astronauts who have been in outer space for 63 days — approximately seven weeks longer than expected ...
