Detailed explanation-1: -The physical properties of space are rich in paradoxes. Space seems empty but contains valuable resources of energy and matter and dangerous fluxes of radiation. Space seems featureless but has hills and valleys of gravitation. Space is harsh and lifeless but offers opportunities for life beyond those of Earth.
Detailed explanation-2: -The three major differences are: atmosphere (vacuum in space), radiation (high level of dangerous particles), and gravity (weightlessness in space). The first difference between the Earth and space is the atmosphere.
Detailed explanation-3: -Radiation. Isolation and confinement. Distance from Earth. Gravity (or lack thereof) Hostile/closed environments. Human research essential to space exploration. 08-May-2019
