The effective dose is used to scale the mortality rate for radiation-induced death from the Japanese survivor data, applying the average of the multiplicative and additive transfer models for solid cancers and the additive transfer model for leukemia by applying life-table methodologies that are based on U.S. population data for background ...

Before sending humans, space agencies used animals to study the effects of space travel on the body. [10] After several years of failed animal recoveries, an Aerobee rocket launch in September 1951 was the first safe return of a monkey and a group of mice from near space altitudes. [ 11 ]
Sunshield full-size test for the James Webb Space Telescope. In spacecraft design, a Sun shield restricts or reduces heat caused by sunlight hitting a spacecraft. [5] An example of use of a thermal shield is on the Infrared Space Observatory. [5] The ISO sunshield helped protect the cryostat from sunlight, and it was also covered with solar ...
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.
A space sunshade or sunshield is a parasol that diverts or otherwise reduces some of the Sun's radiation, preventing it from hitting a spacecraft or planet and thereby reducing its insolation, which results in reduced heating.

Drosophila melanogaster, the common fruit fly, has been used to study the effects of spaceflight on living organisms.. On a July 9, 1946, suborbital V-2 rocket flight, fruit flies became the first living and sentient [citation needed] [] organisms to go to space, and on February 20, 1947, fruit flies safely returned from a suborbital space flight, which paved the way for human exploration.
