Shortest duration Mars mission
« on: 04/13/2017 03:22 AM »
I'm certain that something like this has been proposed before, and probably shot down, but I'm unable to find anything similar in searches. I'm sure someone here will direct me.

Does not seem feasible with the technology described.  No supporting references or documentation.


Shortest more or less credible duration? Sprint missions, about a year, e.g. https://www.wired.com/2012/05/piloted-splitsprint-mission-to-mars-1987/ or http://astronautix.com/m/marsexpedition88.html

Shortest surface stay? Five days http://astronautix.com/b/bygeminitomars.html . Not really credible from a Mars operations point of view

First I've heard of it, but then again I'm not a rocket scientist...  ;)

Interesting though.  However it sounds like it would require a lot of energy for the accelerating and deceleration phases, even with gravity assist, and energy means fuel.  Not to say it can't be done, but it might not be the small vehicles imagined in the proposal.

Also, this is very similar to the Mars cycler, just smaller and with two vehicles to allow a brief stay and short overall mission time.
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

Transfer times far to short for a cycler AFAIK

Trip to Mars can take  longer as long you have artificial gravity, so health problem can be mitigated.
Please check this arrangement. Health come first.
