Orbital Mechanics
The study of the motion of objects in space, particularly how gravity affects their paths. It's the science behind how satellites stay in orbit and how spacecraft travel between planets.
TECHNICAL DEFINITION
Orbital mechanics, or astrodynamics, is the application of Newtonian physics and celestial mechanics to analyze and predict the motion of artificial satellites and spacecraft under gravitational forces, crucial for mission design and navigation.
BACKGROUND
The International Space Station (ISS) is a space station in low Earth orbit (LEO). It is the product of the International Space Station program and is operated by five partner space agencies: NASA, Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). It is the first space station built, maintained and crewed through international cooperation and the largest human spacecraft ever constructed. It is an orbital research station, where scientific experiments in microgravity are conducted and the space environment is studied. Since 2 November 2000, it has hosted the longest continuous presence of humans in space. Alongside Tiangong, it is one of the only two currently operational space stations.
