good thing is - that mining collapse in Chile produced a very valuable information for NASA.

Optimally - it takes 6 months to get to Mars. It will be another one year for next orbital window. However.... at this point right now even in 20 years when we're finally launching men to Mars - it will most likely be one-way flight because we do not have sufficient technology nor fuel for return flight. Not for another several decades till we have a significant technological advancement in propulsion system.

Realize that since it takes 6 months to get to Mars... this requires a massive spaceship. It's too big to build it here and then launch it from Earth. It's not economically and technologically feasible. The argument was said that we should focus on Moon colonization first which can serve as a launching pad for Mars trip. Unfortunately - that project was abruptly cancelled due to... of course!!!..... budget issue and it was placed on hold indefinitely.

[QUOTE="Jiro, post: 1726333, member: 16500"] good thing is - that mining collapse in Chile produced a very valuable information for NASA. Optimally - it takes 6 months to get to Mars. It will be another one year for next orbital window. However.... at this point right now even in 20 years when we're finally launching men to Mars - it will most likely be one-way flight :eek3: because we do not have sufficient technology nor fuel for return flight. Not for another several decades till we have a significant technological advancement in propulsion system. Realize that since it takes 6 months to get to Mars... this requires a massive spaceship. It's too big to build it here and then launch it from Earth. It's not economically and technologically feasible. The argument was said that we should focus on Moon colonization first which can serve as a launching pad for Mars trip.
