Could we get to the moon using only classical mechanics?

SUMMARY

It is definitively possible to send a man to the moon using only classical mechanics, as evidenced by historical missions. The discussion highlights that General Relativity (GR) is not necessary for interplanetary travel due to the minimal differences between GR and classical physics predictions at this scale. Classical equations adequately describe the necessary trajectories and dynamics for lunar missions. Historical evidence confirms that lunar landings have successfully utilized classical mechanics without the need for GR.

PREREQUISITES
  • Understanding of Newtonian physics and classical mechanics
  • Familiarity with orbital mechanics and trajectory calculations
  • Knowledge of historical lunar missions, specifically Apollo missions
  • Basic grasp of the differences between General Relativity and classical physics
NEXT STEPS
  • Research the principles of Newtonian mechanics in space travel
  • Study the trajectory calculations used in the Apollo lunar missions
  • Explore the limitations of General Relativity in practical applications
  • Investigate the historical context and technology of the Apollo program
USEFUL FOR

Aerospace engineers, physics students, historians of science, and anyone interested in the mechanics of space travel.

I'm wondering if it's possible to send a man to the moon using only classical mechanics. If not, where would the classical equations fail?

Of course. That's how we got there in the first place. No one uses General Relativity for interplanetary travel. It's too complicated and the difference between GR's predictions and classical physics' predictions are extremely small at this scale. Small enough to not have to worry about GR at all.
 
It's perfectly possible to fly to the moon using only classical mechanics.
In fact I believe it has already been done several times.
