Breaking through into space travel, humans leaving Earth and defeating gravity, taking steps on the Moon, and various other achievements were pivotal moments in human cultural development. In particular, the scientific and technological advancements stand as an inspiration to the scientific community of students, teachers, and researchers ...
Source: [6] effects on biological damage related to differences between space radiation and x-rays; 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
Radiation in space usually comes from three main sources: The Van Allen radiation belts; Solar proton events and solar energetic particles; and; Galactic cosmic rays. For long-duration missions, the high doses of radiation can damage electronic components and solar cells.

Space can be an unfriendly place for the human body, with microgravity conditions and other factors tampering with our physiology, from head to toe - head, of course, being a primary concern.
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
Even with this small rate of loss, life in the Solar System would disappear in a few hundred thousand years, and the potential total time-integrated BIOTA of 3·10 30 kg-years under the main-sequence Sun would decrease by a factor of 5·10 5, although a still substantial population of 1.2·10 12 biomass-supported humans could exist through the ...
The main advantage of a field propulsion systems is that no propellant is needed, only an energy source. This means that no propellant has to be stored and transported with the space craft which makes it attractive for long term interplanetary or even interstellar crewed missions. [10]
