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).
According to Lew Allen, the initial key design elements were specified by Edwin H. Land.They included i) solid state focal plane array, ii) integrated circuits for complex data processing, iii) large, fast optics with a 2.54 m (100 in) diameter f/2 primary mirror, iv) gigabit/s data link, v) long on-orbit operational lifetime for the imaging satellites, and vi) communication satellites to ...

ADvanced Space Experiment Processor (ADSEP): this thermally controlled facility accommodates experiments in cell technology, model organisms, multiphase fluids, solution chemistry, separation science, microencapsulation, and crystal growth.
The imaginary line around which Earth spins, which goes between the North Pole and South Pole, is tilted about 23° from the oval that describes its orbit around the Sun. Earth always points in the same direction as it moves around the Sun, so for half the year (summer in the Northern Hemisphere), the North Pole is pointed slightly toward the ...
The accompanying Physics Viewpoint [58] said that "The first results from the space-borne Alpha Magnetic Spectrometer confirm an unexplained excess of high-energy positrons in Earth-bound cosmic rays." These results are consistent with the positrons originating from the annihilation of dark matter particles in space, but not yet sufficiently ...
Space manufacturing or In-space manufacturing (ISM in short) is the fabrication, assembly or integration of tangible goods beyond Earth's atmosphere (or more generally, outside a planetary atmosphere), involving the transformation of raw or recycled materials into components, products, or infrastructure in space, [3] where the manufacturing ...
A space station (or orbital station) is a spacecraft which remains in orbit and hosts humans for extended periods of time. It therefore is an artificial satellite featuring habitation facilities . The purpose of maintaining a space station varies depending on the program.
