    Some studies suggest that the projected increase in space travel will damage the ozone layer. [6] [7] A single rocket launch produces 300 tonnes of carbon dioxide, staying longer in the upper atmosphere than emissions caused by airplanes or jets. [8] Thomas Fink, however, argues the long-term benefits of space science offset the ecological ...

    The "Space Transportation System" (NASA's formal name for the overall Shuttle program) was created to transport crewmembers and payloads into low Earth orbits. [10] It would afford the opportunity to conduct science experiments on board the shuttle to be used to study the effects of space flight on humans, animals and plants.

  8. Effects of ionizing radiation in spaceflight - Wikipedia

    en.wikipedia.org/wiki/Effects_of_ionizing...

    Due to the potential negative effects of astronaut exposure to cosmic rays, solar activity may play a role in future space travel. Because galactic cosmic ray fluxes within the Solar System are lower during periods of strong solar activity, interplanetary travel during solar maximum should minimize the average dose to astronauts. [citation needed]

    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.
