Neither of us will live long enough to see the day these barriers are broken:

1-Payload lift capability

2-Adequate construction in space

3-Medical limits on radiation exposure

4-Nutritional requirements

True, at 66 in the nxt couple of weeks, I won’t live long enough to see much more tha I have already.

But Musk’s enterprises gave me hope when it was waning that men will be in space for a long time and living on the Moon and then Mars will be within this century.....................
