Manned missions allow for real time interaction with the environment instead of waiting for sent commands to be processed, and confirmation returned. But manned missions require expensive, large habitable environments and support systems to keep the astronauts alive.
hi
The main difference - is size ! With a crewed space vehicle, you have to make it big enough to accommodate the people, and include their life-support systems, propulsion etc. With an unmanned probe - it only needs to be big enough to house the instrumentation and power (batteries & solar panels).
I think it might be because probes are cheaper and just in case something goes wrong, it would not end up resulting in loss of life. (Just an opinion though.)
How do space probes aid in space exploration
How do space probes aid in space exploration
yes
pros: We can learn lots of things by sending crews and space probes. For without space probes how would we be able to tell the weather. cons: Many humans can die in space if there is a problem with the space craft and billions of dollars will be wasted.
the taint stains
Robot space probes and telescopes
space probes with no human crew
