RE: What exactly is an orbit? An Introduction
Hi, I found some acronyms/abbreviations in this post. This is how they expand:
| Acronym | Explanation |
| F1 | Rocketdyne-developed rocket engine used for Saturn V,SpaceX Falcon 1 (obsolete medium-lift vehicle) |
| apogee | Highest point in an elliptical orbit around Earth (when the orbiter is slowest) |
| perigee | Lowest point in an elliptical orbit around the Earth (when the orbiter is fastest) |
Not too shabby!
