DAY 1: The Tyranny of the Rocket Equation (excerpt)
|
||||
|
||||
PART 1:
|
||||
...
|
||||
Fuel required to launch a given module is based on its mass.
|
||||
Specifically, to find the fuel required for a module, take its mass,
|
||||
divide by three, round down, and subtract 2.
|
||||
...
|
||||
What is the sum of the fuel requirements for all of the modules
|
||||
on your spacecraft?
|
||||
|
||||
PART 2:
|
||||
...
|
||||
So, for each module mass, calculate its fuel and add it to the total.
|
||||
Then, treat the fuel amount you just calculated as the input mass
|
||||
and repeat the process, continuing until a fuel requirement is zero
|
||||
or negative.
|
||||
...
|
||||
What is the sum of the fuel requirements for all of the modules
|
||||
on your spacecraft when also taking into account the mass of the
|
||||
added fuel?
