Should the U.S. spend billions of dollars to return an astronaut to the moon?

During the Cold War, manned space flights were a powerful symbolic image of the success of the U.S. space program. For the Russians to send cosmonauts into space and the Americans to send computers would have been an admission of defeat, a sign of inferiority of the U.S. government. Also, the computerized technology of the 1950s and 1960s was far inferior to what is available today. However, now that the Cold War is at an end, the question remains: why explore the cosmos with manned missions? There seems to be no pressing military or public relations reason for human beings to be sent into space. It is less costly, safer, and does not compromise scientific achievement to send machines to explore space. So why does the U.S. continue to attempt to send manned space missions at great...

While shuttle launches and the International Space Station get all the media coverage, these small, relatively inexpensive unmanned missions are doing important science in the background" (Rahls 2005:1). In the wake of recent budget cuts to NASA, space exploration (and the necessary safety checks for manned space flights) has grown increasingly costly. Ethically speaking, NASA cannot even perform adequate safety checks to guarantee the safety of astronauts.
Unlike humans, robots do not need food, water, or other extraneous accoutrements to keep them alive, and if there is a malfunction, the only loss is a financial one, not a loss of life. "As computers become more capable and reliable, robots of greater complexity will be built to handle even the most challenging assignments. The time for humans to explore space may have come [and gone]…. And, indeed, may have gone forever"…
