CORE DEFINITION

A rocket that fires its engine at the point of maximum speed (usually periapsis) gains the greatest energy increase (highest efficiency) because the kinetic energy of the fuel is also utilized.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The timing of applying force. When you are at a low point (slow speed), investing resources is less effective; when you are at a high point of smooth sailing and maximum speed, that is the best time to 'fire' and increase investment. Adding to prosperity is more efficient than providing aid in adversity.

Anchor fast decisions

Rocket mechanics: With the same amount of fuel, firing at a higher orbital speed yields a greater increase in kinetic energy than at lower speed, because the gain is amplified by the square of the final velocity. The mechanism is 'the higher the speed, the more valuable the acceleration'.

Gravity Assist

A gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes 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 …

Orbital Velocity

The orbital velocity of a celestial body, generally a planet, natural satellite, artificial satellite, or a star in a multiple star system, is the speed at which it orbits the barycenter of the system, usually a more massive body. It can be used to represent the average orbital speed as the body completes one revolution, or its instantaneous orbital speed, i.e., its speed at a specific point in its orbit. The speed of a body at any point in its orbit can be calculated from its distance to the central body; the orbital energy of the body is independent of its position, and is equal to the sum of kinetic energy and potential energy. Thus, under ideal conditions, the orbital speed v {\displaystyle v\,} is: In general: …

Gravitational Lensing

Gravitational lensing, according to general relativity, occurs when light from a background source passes near a gravitational field (such as a galaxy, galaxy cluster, or black hole), causing the light to bend as if through a lens. The degree of bending depends mainly on the strength of the gravitational field. Analyzing the distortion of the background source can help study the properties of the intervening gravitational field acting as a 'lens'. Depending on the scale and effect, gravitational lensing can be divided into strong and weak lensing. Orest Khvolson (1924) and Frantisek Link (1936) are considered the first to discuss this effect in papers, but it is usually associated with Einstein, who calculated it in 1912 and published an article on the subject in 1936. In 1937...
