compare advantages and disadvantages of space exploration and space probes?

It's safer to use space probes, plus there are less considerations which have to be factored into the venture. Space exploration with persons is going to cost much more than it already costs to send unmanned craft. Probes don't weigh as much and don't have human needs which need to be carried along.

Space probes are also a good means of determining the scenario before sending people to the location. It is a much less expensive way to obtain and classify information. It helps us gain a better understanding of what lies ahead, and how best to approach, or not to approach that particular method or location at all. These greatly increase our knowledge of the solar system and hopefully beyond without the risk to human life.

A big disadvantage of space exploration of any kind is the cost of fuel, and the purchase order contract costs which spiral out of control once any space project is being completed. Another disadvantage is human error or disregard of specifications in the construction. With a space probe a great amount of time and money is lost, but with a manned craft, both human life and time and money are lost.

Certainly the best advantage is learning. If we're going to survive as a species, we *need* to send people into space. Learning how to survive on minimal supplies, with limited amounts of energy has direct application to the people here on Earth - we're going to NEED to know how to do those things, especially with a population approaching 6.5 billion. Disadvantages - it's expensive. It's dangerous. It's hard on a person's life to leave the home they've known all their lives for months at a time on a space station.
