NASA Prepares For Space Surgery and Zero Gravity Blood

We need robots on Earth, and since every task in space is dangerous and since humans are a burden to support, there is no functional reason for the desperate rush to send people.

Except there's also the usual procrastination problem. If we don't start now, when we already are very capable of doing so, then when will the better time come along, if ever?

We should perfect machines before sending tourists.

Why? We didn't wait for perfect machines before we built an industrial civilization. Tourists who visit dangerous places, like Mt. Everest, don't wait for perfect machines either.

Do you expect to be alive when either humans land on Mars or machines are perfected? If not, then you don't have the time.
