** Speculate on what strategies are required to get a spacecraft to theMoon, which is about 60 Earth radii away, and back.; Note that you can if you wishexperiment with this situation by following the instructions for 2d Planet; just becareful to set your original parameters so that the Moon is visible. **
To begin with the actual data from the Apollo 11 mission, the Apollo spacecraft reached Earth parking orbit after 11 minutes. After one and a half Earth orbits the Saturn thrusters fired and the astronauts began their journey to the Moon. As the Apollo orbited to the far side of the Moon for the 14th time, the astronauts boarded the Lunar Module (LM) and commenced a 30-second burn that would put the LM on the Apollo 10 descent trajectory down to 50,000 feet. A 12.5 minute burn then followed that brought the LM down to the surface.
Incidentally the on-board computers used during that mission might or might not have been capable of running this simulation at its current resolution and speed (probably not). They used more precise data and took into account anomalies in mass distributions, especially of the Moon, and they used more sophisticated numerical methods (it's the only way their computers could figure thigs quickly enough) but those computers were very primitive by current standards.
