For example, on the International Space Station the Earth's gravity is nearly 90% as strong as at the surface. Objects orbiting in space would not remain in orbit if not for the gravitational force, and gravitational fields extend even into the depths of intergalactic space.

Space environment is a branch of astronautics, aerospace engineering and space physics that seeks to understand and address conditions existing in space that affect the design and operation of spacecraft.
With current technology severely limiting the velocity of space travel, the differences experienced in practice are minuscule. After 6 months on the International Space Station (ISS), orbiting Earth at a speed of about 7,700 m/s, an astronaut would have aged about 0.005 seconds less than he would have on Earth. [11]
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1] [1] [2]
Space technology is technology for use in outer space. Space technology includes space vehicles such as spacecraft , satellites , space stations and orbital launch vehicles ; deep-space communication ; in-space propulsion ; and a wide variety of other technologies including support infrastructure equipment, and procedures .
For example, today's technology such as GPS did not suddenly come into existence; in fact, it is laid down in the 18th century and developed throughout time. The first space is real and tangible, and it is also known as physical space. Second space is the unblocking space. This type of space refers to the process whereby routine pathways of ...
The science and engineering of spacefaring and spaceflight, a subset of Aerospace engineering (which includes atmospheric flight) Space technology is technology for use in outer space, in travel or other activities beyond Earth's atmosphere, for purposes such as spaceflight, space exploration, and Earth observation. Spaceflight. Human spaceflight
the space-time aquarium (or space-time cube), which displays individual paths in axonometric graphical projection of space and time coordinates; the space-time prism , which shows individuals' possible behavior in time-space given their capability constraints and coupling constraints;
