Firstly, LCROSS has a great meaning to human space exploration.
Secondly, 79 millions NASA has spent on it was absolutely NOT a huge number as you thought.
Thirdly, the impacts have no harmful effects on Moon. It's ridiculous when somebody says that "oh no, LCROSS may change the Moon's orbit".
Lat but not least, saving our Earth and exploring the outer space are two different matters.
You can save money by saving energy, stopping the war, but not cutting of the budget for human exploration. There would have been no America if Columbus have had to cancel his trip due to budget constraint. Lol.
Please think carefully and learn more about things if you want to criticize them.
