... Although it is possible that on some planets life might change at a rate similar to Earth’s, there is no reason to assume that it must. On some planets it seems highly unlikely life would evolve at the same rate as Earth’s. 2) Although life on a planet may evolve into complex, multi-celled forms, th ...

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.
