For example, as the Earth's rotational velocity is 465 m/s at the equator, a rocket launched tangentially from the Earth's equator to the east requires an initial velocity of about 10.735 km/s relative to the moving surface at the point of launch to escape whereas a rocket launched tangentially from the Earth's equator to the west requires an ...
Escape velocity from the sun without the influence of Earth is 42.1 km/s. In order to reach this speed, it is highly advantageous to use as a boost the orbital speed of the Earth around the Sun, which is 29.78 km/s. By later passing near a planet, a probe can gain extra speed from a gravity assist.
On January 19, 2006, New Horizons was launched from Cape Canaveral Air Force Station by an Atlas V rocket directly into an Earth-and-solar escape trajectory with a speed of about 16.26 km/s (10.10 mi/s; 58,500 km/h; 36,400 mph). It was the fastest (average speed with respect to Earth) human-made object ever launched from Earth.
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]
The depth of the potential well depends on the vehicle's position, and the energy depends on the vehicle's speed. If the kinetic energy exceeds the potential energy then escape occurs. At the Earth's surface this occurs at a speed of 11.2 km/s (25,000 mph), but in practice a much higher speed is needed due to airdrag.

MAVEN, a Mars-bound spacecraft, was launched into a trajectory with a characteristic energy of 12.2 km 2 /s 2 with respect to the Earth. [1] When simplified to a two-body problem, this would mean the MAVEN escaped Earth on a hyperbolic trajectory slowly decreasing its speed towards =.
Orbit of AMC-8 satellite around the Earth in 2000, transferring from a geostationary transfer orbit to a geostationary orbit. An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit.
