A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

The specific impulse of a rocket can be defined in terms of thrust per unit mass flow of propellant. This is an equally valid (and in some ways somewhat simpler) way of defining the effectiveness of a rocket propellant. For a rocket, the specific impulse defined in this way is simply the effective exhaust velocity relative to the rocket, v e ...
The formula for an escape velocity is derived as follows. The specific energy (energy per unit mass ) of any space vehicle is composed of two components, the specific potential energy and the specific kinetic energy .
Relativistic rocket means any spacecraft that travels close enough to light speed for relativistic effects to become significant. The meaning of "significant" is a matter of context, but often a threshold velocity of 30% to 50% of the speed of light (0.3 c to 0.5 c ) is used.
Annie Easley (April 23, 1933 – June 25, 2011) was an African American computer scientist and mathematician who made critical contributions to NASA's rocket systems and energy technologies. Easley's early work involved running simulations at NASA's Plum Brook Reactor Facility and studying the effects of rocket launches on earth's ozone layer.
The commercial mission is set to launch from Rocket Lab Launch Complex 1 on October 19, 2024, for a confidential customer. This marks the company’s fastest turnaround, achieving the launch in ...
