A fundamental step in overcoming this challenge is trying to understand the effects of long-term space travel on the human body. In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars. [9] [10]
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.

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.
They also provided the most in-depth data on record regarding the effects of space travel on the human body. New research based on this data details changes in the brain, heart, muscles, kidneys ...
Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself , while others are injuries that could have occurred on Earth's surface.
Draining the charged particles from the Van Allen belts would open up new orbits for satellites and make travel safer for astronauts. [ 42 ] High Voltage Orbiting Long Tether, or HiVOLT, is a concept proposed by Russian physicist V. V. Danilov and further refined by Robert P. Hoyt and Robert L. Forward for draining and removing the radiation ...

Aldrin held that reusable spacecraft were the key in making space travel affordable, stating that the use of "passenger space travel is a huge potential market big enough to justify the creation of reusable launch vehicles". [76] Space tourism is a next step in the use of reusable vehicles in the commercialization of space.
