We should keep sending people into space. There are new worlds out there that may hold answers to many of the questions we now have. New ideas have come along through the space program such as most of the wireless technology and many medical breakthroughs. If we take away the challange of space inhabitation then many a great mind will be put out. The U.S. should continue to send humans to space.
Robots can do the job, but there is so much more that a person can see and learn in space.
The government should stop sending humans into space. Sending humans costs more money. All the government is doing is spending money that could be put to a better use. If Christopher Columbus had not tried to find new land, Europe would have not known that the Americas existed. I think they should not send any more humans into space because the price tag on the flights with humans on board is more expensive than with just robots on board.
