The Apollo 16 mission was in Apr 1972 so the epoch should be more like 721xx. Also the revs/day of 15.2... is way to high for an (fitted) elliptical orbit around the Earth that reaches the Moon. I would expect something around .1 or .2 instead. > Nova For Windows doesn't see these as valid elements. Probably because the > satellite has escaped Earth orbit.
