If there was an urgent need to launch a rocket to the ISS, how long would it take to have a rocket ready to launch?
I am trying to understand what factors take up the time to prepare for a rocket launch.
Here are some clarifications to limit scope. I am curious how long it takes to prep an emergency launch from a rocketry perspective.
Assume there was an urgent need to deliver a small, lightweight package with something vital such as medicine or a replacement circuit board that is available.
Assume we CAN use an existing rocket.
Assume the rocket is NOT sitting ready on a launchpad.
Assume travel to the ISS is within the capabilities of the rocket.
