While unmanned space exploration is not as romantic as manned space flight, it is more functional. Exploring space is extremely expensive and governments have to consider the practicalities of exploration more than the glamour. Scientifically, little is gained by manned flight over unmanned flight. In terms of increasing interest in space flight, it is questionable whether states encouraging interest in space exploration is the best thing at all. They could simply use space exploration, especially exciting manned voyages, as means of distracting public attention from domestic problems. It is better for people to be focused on life on this planet than on the mysteries of space.
