8.1.1 Humans or robots?
In this video, Ian Crawford discusses the advantage of human exploration over robotic missions; however, there are pros and cons for each. Robotic missions are a lot cheaper than manned missions and do not need to return to Earth, but humans are a lot more efficient at exploration. Missions to the Moon still hold a lot of prestige. Recent missions from Japan, China and India have been used by those countries as a way to demonstrate technological capability. Scientific knowledge to complement that of the Apollo era has also been obtained and international collaboration has been strengthened.
