A Subway Map of the Solar System

In astrodynamics a Δv or delta-v (literally “change in velocity”) is a measure of the amount of “effort” that is needed to change from one trajectory to another by making an orbital maneuver. It is a scalar that has the units of speed.

The rocket equation shows that the required amount of propellant dramatically increases, with increasing delta-v.

Therefore in modern spacecraft propulsion systems considerable study is put into reducing the total delta-v needed for a given spaceflight, as well as designing spacecraft that are capable of producing a large delta-v.

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
