Space exploration is a very important activity that humans have a big interest in. For whatever reason, we just obsessed with knowing whether or not we're alone here in space.
We have sent many spacecrafts up into outer space by way of powerful rockets to explore planets, moons, comets, and more. Those spacecrafts can have either a human or a robot (rover) on board, and you may ask yourself, which is the better choice?
There is really no definitive answer because there are pros and cons to both obviously, humans are a good choice for certain situations because humans are very independent and can get things done without too much help from another human on a spacecraft, or even here on Earth. Robots are good for situations where we might want to continue exploring an area without any oxygen or food.
Obviously, humans also have to come back to Earth. Added on top of the expenses of supplies, it is more expensive to send humans to space than it is robots. Sending robots up into space also eliminates the chance that a person will die mid-air in a rocket accident.
Which do you think is better?
