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 International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, -radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.
The future of space exploration involves both telescopic and physical explorations of space by robotic spacecraft and human spaceflight. Near-term physical exploration missions, focused on obtaining new information about the Solar System , are planned and announced by both national and private organisations.
Spacecraft in Joe Haldeman's 1974 novel The Forever War make extensive use of constant acceleration; they require elaborate safety equipment to keep their occupants alive at high acceleration (up to 25 g), and accelerate at 1 g even when "at rest" to provide humans with a comfortable level of gravity.
Vast Space is a private company that proposes to build the world's first artificial gravity space station using the rotating spacecraft concept. [23] A Mars gravity simulator could be built on the Moon to prepare for Mars missions. The surface gravity of Mars is somewhat more than twice that of the Moon.
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry .
The 2024 Nobel Prize in physics has been awarded to John Hopfield and Geoffrey Hinton for their fundamental discoveries in machine learning, which paved the way for how artificial intelligence is ...
Space vehicle – Combination of launch vehicle and spacecraft Launch vehicle – Rocket used to carry a spacecraft into space; Spacecraft – Vehicle or machine designed to fly in space; Spaceflight – Flight into or through outer space; Space research – Scientific studies carried out using scientific equipment in outer space
