I always imagined that it would be possible for me to see space travel where we humans would visit Mars and the Moon, for example.
I don't know if I'll be able to embark on one of these trips, but my children and grandchildren will certainly be able to.
I imagine it will be as common as if it were a small bus trip we take here. The next 50 years will be incredible for space exploration.
You will see a time when there are regular flights to the moon at least. I am not sure about Mars.
The moon will be fine with me.
Mars will actually take much longer.
It is like a 6 month trip. Too much in a tube.
It takes a long time... Traveling for a day and a half by car is exhausting, imagine half a year.
