I think this is a very cool thing to do. Im tired of the ignorant liberals who think this, and NASA are a waist of money. Do you know how much metals are probably on Mars? How about new alloys, metals, or even other compounds that we could use on earth for our needs in materials like semiconductors and medicines and plastics. Ever wonder how much gold, platinum and diamonds are on the moon or other planets? How about doing some actual research before complaining about a new subject all the time. And by the way, there are lots of money, programs, and associatoins for curing cancer. Go look at how much has been done as a result of space age technology. Go do some research before whining all the time, you are bringing down the moral of everyone else.
