Yes, that is correct. Neil DeGrasse Tyson said that instead of going to Mars, we should focus on solving our problem here on Earth.
I agree with that but I also agree that we can do both. We absolutely have to solve problems of Earth but we should also be preparing Mars for a second home. That is the whole point of guaranteeing survival in case anything happens to Earth in say, 1000 years.
Absolutely! We should and we have to do both and I want us to do both too. It will be like living in the future.
It sure will! :)
