... The pull of The Moon makes tide on The Earth. When the Moon is in the horizon it pulls the water away from you so you have low tide. When the Moon is highest in the Sky it pulls the see so you have high tide. You also have high tide app. 12 hours later. When the Earth rotates around its axis, the Mo ...

Near Earth Asteroids: The Celestial Chariots
... A final orbital consideration is the inclination of the asteroids orbits relative to Earth and Mars. In an Ecliptic plane reference frame, which passes through the Sun and Earth orbit, Mars orbit has an inclination of -1.8 degrees. In order for Asteroids to approach both Earth and Mars, they must or ...

Gravity assist
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing-by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically in order to save propellant, time, and expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed and/or redirect its path.The ""assist"" is provided by the motion of the gravitating body as it pulls on the spacecraft. The techniques were first proposed as a mid-course manoeuvre in 1961 by Michael Minovitch working on the three-body problem. It was used by interplanetary probes from Mariner 10 onwards, including the two Voyager probes' notable flybys of Jupiter and Saturn.
