RE:

What are the advantages and disadvantages of space exploration?

What other pros and cons are there besides these:

Cons:

Too expensive

Dangerous

Possibility of missions failing

Creates competition among countries - could lead to war (it's a little far-fetched but I'm desperate haha)

Pros:

To learn about space

Offer career...

It depends on our capabilities technologically. And the exact purpose for why a shuttle is launched. There are many missions that do not REQUIRE and individual to be there. There are other missions that DO require a human to complete the tasks. Robots cannot function and think in the complex ways that humans can. Once a machine can do a triple heelflip on a skateboard, then astronauts probably won't be needed. "ROBONAUT" the robotic astronaut is in space right now. GM-NASA.

other pros :

asteroid collision mitigation

communication satellites

weather satellites

spy satellites (also a con)

mining of asteroids

other cons

satellite might re-enter atmosphere and pollute earth (radioactive material) or cause property damage when bits of it land

pollutes atmosphere (with rocket exhaust)

uses earth's resources

space junk accumulation
