Direct human presence in space was achieved with Yuri Gagarin flying a space capsule in 1961 for one orbit around Earth for the first time. While direct human presence in open space, by exiting a spacecraft in a spacesuit, a so-called extravehicular activity, has been achieved since the first person to do so, Alexei Leonov, in 1965.
The physician William Barrett, author of the book Death-Bed Visions (1926), collected anecdotes of people who had claimed to have experienced visions of deceased friends and relatives, the sound of music and other deathbed phenomena. [12] Barrett was a Christian spiritualist and believed the visions were evidence for spirit communication. [13]
Crew living on the International Space Station (ISS) are partially protected from the space environment by Earth's magnetic field, as the magnetosphere deflects solar wind around the Earth and the ISS. Nevertheless, solar flares are powerful enough to warp and penetrate the magnetic defences, and so are still a hazard to the crew.
Three of the flights had flown above the Kármán line (edge of space), and one was intended to do so. In each of these accidents the entire crew was killed. As of December 2023, a total of 676 people have flown into space and 19 of them have died. This sets the current statistical fatality rate at 2.8 percent.
A near-death experience (NDE) is a profound personal experience associated with death or impending death, which researchers describe as having similar characteristics.
Death by GPS refers to the death of people attributable, in part, to following GPS directions or GPS maps.

The habitability of natural satellites is the potential of moons to provide habitats for life, though it is not an indicator that they harbor it. Natural satellites are expected to outnumber planets by a large margin and the study of their habitability is therefore important to astrobiology and the search for extraterrestrial life .
