I hate when people criticize and don’t offer a solution. The obvious follow up would be to calculate exactly how big of a rocket must be built to reach the moon

I hate when people criticize and don’t offer a solution. The obvious follow up would be to calculate exactly how big of a rocket must be built to reach the moon, or even deep space.
- wh313 7y agoBeing able to go to the moon also provides the ability to go to deep space (just point the rocket away from the moon). Escape velocity is 11,186 m/s, so (assuming a rocket with specific impulse similar to the one in the post): 11,186 m/s = 263.1 s * 9.81 m/s^2 * ln( x kg / 20,800 kg ) That's roughly 1.58591*10^6 kg of propellant, which is actually less that what's in the first stage of a Saturn V. Of course, this doesn't include air resistance or anything beyond just hitting escape velocity and leaving Earth's orbit.
