Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy , predates reliable recorded history , it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to ...
Space research is scientific study carried out in outer space, and by studying outer space. From the use of space technology to the observable universe, space research is a wide research field. Earth science, materials science, biology, medicine, and physics all apply to the space research environment. The term includes scientific payloads at ...
Space physics. Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy, aurorae, planetary ionospheres and magnetospheres, radiation belts, and space weather (collectively known as solar-terrestrial physics ...
Space physics – study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System. Solar physics – Sun and its interaction with the remainder of the Solar System and interstellar space. Stellar astronomy – concerned with Star formation, physical properties, main sequence life span, variability ...
When in space, the purpose of a propulsion system is to change the velocity, or v, of a spacecraft. Because this is more difficult for more massive spacecraft, designers generally discuss spacecraft performance in amount of change in momentum per unit of propellant consumed also called specific impulse.

The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
The Center for the Advancement of Science in Space ( CASIS ), a non-profit organization, is the manager of the International Space Station United States National Laboratory, a US government -funded laboratory with principal research facilities located in the United States Orbital Segment of the International Space Station (ISS).
According to the United States National Center for Education Statistics, "scientific literacy is the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity".
