Question:What are the disadvantages of using unmanned space probes to explore the Solar System?

The main drawback of unmanned space probes is that they are less adaptable to changes in circumstance than a Human being. If something goes wrong on an unmanned space probe, there is no one there to fix it. A manned space probe can still fail, but there are more options, a single fuse going would not end a manned mission, but will kill an unmanned space probe.
