Why does it seem so challenging now to send a manned crew to the moon, when we were able to accomplish this over 50 years ago?
In: Economics
Launching, landing, and re-launching anything with mass is expensive.
The more mass, the more expensive.
A person weighs ~76 Kg.
Then needs water and food.
And pressurized atmosphere.
And if that person’s brain doesn’t get oxygen for ~2 minutes, it catastrophically fails.
Our bodies have evolved for a billion years to live on this planet, and this is where our bodies will stay.
But I am wholeheartedly for space exploration. The Rosetta/Philae mission to comet Churyumov-Gerasimenko was super cool.
I just don’t think a person can do anything in space that a robot can’t do safer, better, and most importantly, less expensive.
