Should money be spent on space exploration?

I THINK THAT THE GOVERNMENT SHOULD SPEND MONEY ON SPACE EXPLORATION. I MEAN WHY NOT, WE HAVE THE INTERNATIONAL SPACE STATION UP THERE. WE NEED TO EXPOLRE SOME MORE. I THINK THAT THE US SHOULD GO BACK TO THE MOON. MAYBE EVEN TAKE A TRIP TO MARS. LANDING A SHIP ON MARS WOULD BE SO AWESOME. IT WOULD BE A MILE-STONE FOR ALL MAN KIND. I THINK THAT WE NEED MORE SATELITES UP THERE THAT WAY WE CAN SEE WHAT IS OUT THERE OR WHAT MAY BE COMING OUR WAY. WE NEVER KNOW, WITH THOSE SATELITES WE MIGHT FIND LIFE SOMEWHERE ELSE! THIS IS 1 REASON WHY I THINK SPACE EXPLORATION IS NESSECARY!
