Some of the things NASA (National Aeronautics and Space Administration) has done is taught humans about things far beyond our planet earth and lead most trips to the moon.
Mainly because it costs a lot of money. NASA only has a limited budget, and money spent on moon exploration is money that can't be spent on other stuff, like the International Space Station and Mars exploration. A second reason is that it's dangerous. Apollo 13's crew nearly all died, and there's no guarantee that if we sent more humans there they wouldn't have their lives put at risk. It's likely that most moon exploration in the near future will be done by robots.

I think it's the main director of the space
NASA has sent probes to Mars, which is much further from Earth than the Moon.
Curiosity and ego, to prove it could be done.
Yes, there is life on our planet Earth, and that is part of the Milky Way. Life outside our planet Earth has not been confirmed yet, but that doesn't mean much, since no space exploration has been done outside our own Solar System.Yes, there is life on our planet Earth, and that is part of the Milky Way.

Never, Eris was explored only by telescopes.
There you have it ... the answer to your own question: It isn't just a waste of money, therefore it continues to be done.

Many different experiments are done on the space station. There have been experiments done on Salmonella; Tethered Satellite System; seeing if a rose smelled different in space; building protein crystals; building films or materials in space; and studying nematodes in space.

Man has not physically been to Mercury but un-manned robots have been there. These robots have helped us to better understand our distant neighboring planet.
