Escape speed at a distance d from the center of a spherically symmetric primary body (such as a star or a planet) with mass M is given by the formula [2] [3] = = where: G is the universal gravitational constant (G ≈ 6.67×10 −11 m 3 ·kg −1 ·s −2)
"The first 1000-year-old is probably only ~10 years younger than the first 150-year-old."–Aubrey de Grey, 2005 [1]. In the life extension movement, longevity escape velocity (LEV), actuarial escape velocity [2] or biological escape velocity [3] is a hypothetical situation in which one's remaining life expectancy (not life expectancy at birth) is extended longer than the time that is passing.
Escape Velocity is a single-player role-playing space trading and combat video game series first introduced in 1996 by Ambrosia Software for the Macintosh.Two other similar games based on the original, EV Override and Escape Velocity Nova, followed in 1998 and 2002 respectively, the latter of which is also available on Microsoft Windows.
One of the best-known examples of an event horizon derives from general relativity's description of a black hole, a celestial object so dense that no nearby matter or radiation can escape its gravitational field. Often, this is described as the boundary within which the black hole's escape velocity is greater than the speed of light.
An orbit insertion maneuver involves either deceleration from a speed in excess of the respective body's escape velocity, or acceleration to it from a lower speed. When the result is a transfer orbit, e.g. a descent orbit insertion, the maneuver is an orbit injection.

Luna 1 became the first artificial object to reach the escape velocity of the Earth, [14] along with its carrier rocket's 1,472-kilogram (3,245 lb) [2] upper stage, which it separated from after being the first spacecraft to reach heliocentric orbit. [1] It remains in orbit around the Sun, between the orbits of Earth and Mars. [2]
In 1926–1929, Tsiolkovsky solved the practical problem regarding the role played by rocket fuel in getting to escape velocity and leaving the Earth. He showed that the final speed of the rocket depends on the rate of gas flowing from it and on how the weight of the fuel relates to the weight of the empty rocket.
