When scheduling EME contacts, which of these conditions will generally result in the least path loss?
Pick an answer to check it.
Answer: A. When the Moon is at perigee
Perigee is when the moon is closest to Earth, so the round trip is shortest and path loss is lowest. At apogee the moon is farthest away.
Tip: Perigee = proximity = less loss.
