The concept of gravity shielding is a common concept in science fiction literature, especially for space travel. One of the first and best known examples is the fictional gravity shielding substance "Cavorite" that appears in H. G. Wells's classic 1901 novel The First Men in the Moon. Wells was promptly criticized for using it by Jules Verne. [3]
The ansible was the basis for creating a specific kind of interstellar civilization, where communications between far-flung stars are instantaneous, but humans can only travel at relativistic speeds. Under these conditions, a full-fledged galactic empire is not possible, but there is a looser interstellar organization, in which several of Le ...
A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
2015: The NASA-designed Hermes in the film The Martian was capable of space travel to Mars. 2018: A planetarium movie Mars 1001 shows a fictional mission to Mars employing a rotating spacecraft. Fallout 76 includes a ruined space station that has a rotating wheel on it in a location called The Crater.
The following outline is provided as an overview and topical guide to space science: Space science – field that encompasses all of the scientific disciplines that involve space exploration and study natural phenomena and physical bodies occurring in outer space, such as space medicine and astrobiology.

The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
A space rendezvous is a sequence of orbital maneuvers during which two spacecraft, one of which is often a space station, arrive at the same orbit and approach to a very close distance (e.g. within visual contact).
"Sky Lift" is a science fiction short story by Robert A. Heinlein, first published 1953. In the story, a torchship pilot lights out from Earth orbit to Pluto on a mission to deliver a cure to a plague ravaging a research station. [12] Tau Zero, a hard science fiction novel by Poul Anderson, has a spaceship using a constant acceleration drive.
