Moon landings are a better challenge, but they are much harder to pull off. We've been stuck in Earth orbit since the 1970's because the political will to go back go the Moon (and spend the money) isn't there. While I'm not even a well-read amateur on the subject of lunar exploration, I do know that getting people there and back requires a much greater expenditure of energy, which translates into much greater cost than an orbital destination. While I firmly agree that we should be returning to the Moon (and exploiting lunar resources), the political will just hasn't been there.
Just wait till China (or worse, India!) puts something significant on the lunar surface. Then you'll see the political will return like a bad case of acid reflux.
