Space Time Relativity: Time Dilation

Time dilation explains why two working clocks will report different times after different accelerations. For example, astronauts come back from missions slightly younger than they would be if they had stayed on earth, and GPS satellites need to adjust for similar bending of spacetime in order to coordinate with systems on earth.
Astronauts travelling at great velocities actually experience minor time dilation effects. If the astronauts had a clear view of earth, they would see events and clocks moving faster than usual. On the other hand, the mission-control crew back on earth would see the events and clocks on the accelerated ship as moving slower. With current technology limiting the velocities of astronauts, these differences are currently minuscule; after 6 months on a space station, an astronaut crew is roughly 0.007 seconds younger than they would be if they had stayed on earth.
To be clear about time dilation, the local experience of time passing never actually changes for anyone (i.e. the astronauts on the ship and the mission-control crew on earth each feel normal). Both teams’ clocks work perfectly too - it is not a mechanical malfunction. Nevertheless, there has repeatedly been documented differences in clock speed, and this is because the laws of nature mean time itself (i.e. spacetime) will operate differently on earth than on the relatively faster moving ship.
Although modern situations cause only minor time dilation effects (e.g. 0.007 second disparity between clocks), the effects would be greater if, instead of travelling at the speed of the orbiting space station (about 0.8km/s), the crew were travelling faster and therefore closer to the speed of light (300,000 km/s). As an illustration, astronauts accelerated beyond modern capabilities would experience greater time dilation: a planned meeting might require the astronauts to set their clocks to count exactly 80 years, whereas mission control - back on earth - might need to count 81 years.
Time dilation can arise from:
The relative velocity of motion between two observers (the above example), or
The difference in their distance from a gravitational mass.
