This former Nasa scientist and wealthy financier wants to partly sponsor a two-person ( man and wife team ) flyby Mars mission in 2018. Does anyone have any thoughts on whether the game would be worth the candle, in both monetary and scientific terms?

There may be some who would think it well worth the money to send their mother-in-law on the trip.

Regards, David

I assume it will be one-way only?

Not a one-way trip - this from the Spaceflight Now website:

The self-made millionaire who paid for his own trip to the International Space Station a decade ago as the world's first orbital tourist wants to send a two-person crew on a 501-day flyby of Mars in 2018, skimming a mere 100 miles above the red planet's surface before looping back for a high-stakes return to Earth.

I haven't read any of the articles about this but my first reaction is that it sounds highly improbable.

Given a 5-year timescale, it sounds as though the spacecraft used will have to be something in use as of today or a modification thereof. As far as I'm aware, there isn't anything presently capable of carrying a crew on a round trip to Mars?


Best Wishes,

Geoff

Consider, too, the possibility that, in such a confined space and for such a long period of time, the marital couple might nag each other to death over whose turn it is to wash the dishes and feed the cat ( the hairless breed ), etc. :wink:

I think we're rather more likely to see the Google Lunar X Prize challenge reach fruition than any manned Mars mission,

http://www.bbc.co.uk/news/magazine-21685995

At least some of the hardware is well into the testing phase and suitable launch vehicles are already available.

Then there's the important question of whether the Moon will be plundered. Personally, I'm sceptical about that happening too because the cost of extraction and retrieval of large volumes of lunar resources must surely prove prohibitive?

Perhaps a modified Orion could get a small crew to Mars and back (simply setting aside all the attendant psychological and physiological considerations!) but I'm convinced it's going to take rather more than 5 years before we see it happen.


Best Wishes,

Geoff

See Prof. Gerard K O'Neill Wikipedia re. costs of Moon material.

Earth itself holds vast natural resources, including "rare earths", which, contrary to popular belief, are not rare. Space mining would surely be surplus to requirements.
