SOLAR SYSTEM

Detailed explanation-1: -Deep space exploration is the branch of astronomy, astronautics and space technology that is involved with the exploration of distant regions of outer space. Physical exploration of space is conducted both by human spaceflights (deep-space astronautics) and by robotic spacecraft.

Detailed explanation-2: -Spacecraft operate at very high velocities compared to velocities we are familiar with in transportation and ballistics here on our planet. Since spacecraft velocities do not approach a significant fraction of the speed of light, Newtonian physics serves well for operating and navigating throughout the solar system.

Detailed explanation-3: -Astronomy – Studying planets, stars, and galaxies They conduct astronomical research by planning experiments and observations with telescopes located both on Earth and in space.

Detailed explanation-4: -space science, body of scientific knowledge as it relates to space exploration; it is sometimes also called astronautics.
