Detailed explanation-1: -The harsh environment of space includes exposure to extreme heat and cold cycling, ultrahigh vacuum, atomic oxygen, high-energy radiation, and debris impact. Knowing how materials and technology will perform in these conditions is necessary for future mission success.
Detailed explanation-2: -Star Wars would have you believe that the greatest challenges to space travel is asteroids, lack of resources like water or fuel, or even the threat of unfriendly, intelligent alien life. But in reality, scientists are finding that the biggest obstacle to today’s space travel is dust. Yes, space dust.
Detailed explanation-3: -First, with telescopes, then with satellites, then space rovers, and ultimately with manned spacecraft.
Detailed explanation-4: -Living in space can be risky! Aside from the threats from space debris and malfunctioning technology, space radiation can present dangers to space explorers, lack of gravity can result in physiological issues, and psychological issues can be caused by isolation and confinement.
Detailed explanation-5: -Radiation. Isolation and confinement. Distance from Earth. Gravity (or lack thereof) Hostile/closed environments. Human research essential to space exploration. 08-May-2019
Detailed explanation-6: -Space Radiation. Isolation and Confinement. Distance from Earth. Gravity Fields. Hostile/Closed Environments. 02-Feb-2021
