According to a news story today, NASA is forecasting that men and women may well travel to Mars by 2035. It might be a 10 month trip.
The NASA spokesman indicated that this timetable admittedly depends not only on sufficient funding but also on some technologies that haven't been created yet!
Nonetheless, 2035 is not far away. And, I imagine there is a real possibility that by then the United States may be working with other global powers, like China and India, as well as Russia, to develop the needed technologies, or at least we can hope for such global cooperation.
My reaction? Yikes!
