Manned Mars Missions --"The Cosmic Threat"
Manned Mars Missions --"The Cosmic Threat"
The Daily Galaxy: News from Planet Earth & Beyond It doesn’t look to good for those planning a trip to Mars and critical for those tying to coming back. I know they will find a way around this in time but for right now it looks like game over. wc

I found "Packing for Mars" by Mary Roach an entertaining and balanced read on the whole "what would it take to go to Mars" and what it takes to go into space in general. She does hit on some things such as the cosmic radiation problem and the bone loss problem which have not really been dealt with satisfactorily given the time of exposure to both interplanetary space and microgravity involved. It isn't bleak, just noting that there is still stuff that needs to be worked on besides propulsion systems.

the lesser gravity makes the brain malfunction also.

Unless something can be done to limit the amount of exposure to radiation this project may never happen. To me it’s a shame. wc

If NASA's experimental Electromagnetic (EM) Drive actually works (we may need to modify Newton's Third Law of Motion to explain it), the flight time to Mars might be cut down considerably -- 70 days, according to recent news reports.
See Evaluating NASA’s Futuristic EM Drive | NASASpaceFlight.com and NASA tests 'fuel-free' space travel that could one day see humans reach moon in FOUR HOURS | Nature | News | Daily Express While the possibility of reaching Mars in only 10 weeks is exciting, the possibilities of "fuel-less" thrusters is immense. Imagine keeping satellites and space stations in orbit indefinitely without replacing propellant, for example. David T. Okamura Last edited by dto; 05-06-2015 at 12:07 PM. Reason: Formatting problems
