Incidently, why is spacex an instantaneous launch window?

The necessity of an "instantaneous" launch window is due to physics: Any time a spaceship needs to catch up to the International Space Station, it must launch as the giant facility flies overhead. Falcon 9's ultracold fuel also warms up and vents out as it sits on the launchpad.

Quite so, what is the launch window for Mars? The duration of the daily launch windows varied from day to day.

The Perseverance rover will land on Mars on Feb. 18, 2021, at around noon PST (3 p.m. EST/8 p.m. UTC).

Yet, what does launch window mean?

The launch window is a term used to describe a time period in which a particular mission must be launched. If the spacecraft intends to rendezvous with another spacecraft, a planet, or other point in space, the launch must be carefully timed so that the orbits overlap at some point in the future.

A rockets engines are not used to directly counter gravity. They are used to accellerate the vehicle to orbital velocity also called escape velocity.

What are the stages of a rocket launch?
