(BBC-US)   Elon looks to 2024 for first Mars mission, assuming the construction of his secret solar-powered volcanic island underground lair continues on schedule. But if the wooly avian raptors get out of their cryo-stasis fields again, all bets are off   ( bbc.com) divider line

Manned Mars missions aren't going to happen until we start using nuclear engines.  Hopefully, we can modify the Limited Test Ban Treaty to allow nuclear explosions in space for propulsive purposes.  If we build an Orion-class ship powered by nuclear bombs, all of the other difficulties involved in getting to and from Mars largely evaporate:  Food, water, air, radiation protection, etc all become much easier when total mission time is less than a year in total than when mission time stretches out to 3 years.

Did he really call it the BFR?

Hahahahahahaha. That's fantastic.

That was a bit confusing. I had to wiki to see if the term nuclear was used for rocket engines. It is; I just didn't remember.

Wiki has a fascinating table on what's been tried and what's been postulated:

Eliminate the radiation exposure by massively increasing the radiation exposure?

There are much better ways of using fission systems for propulsion.

Thinking of something like NERVA? That'd certainly work, and refuelling it at mars wouldn't be any more complex than refuelling their methane / oxygen rockets. Plus there's the whole benefit of landing a nuclear reactor on mars - lots of metals are extractable from martian regolith with that much power on tap, which'd significantly cut down on needed transport of construction materials.

I'd rather send a manned mission to titan.  Mars is just one tick away from going to the moon.  Titan has atmospheric pressure and actual interesting features like oceans of stuff, clouds, weather, etc.

although I"m not sure how much radiation saturn puts out and how much titan can deflect.

Gee, I wonder what sort of application there might be for transporting 100 "passengers" from a base in the U.S. to anywhere in the world in less than 40 minutes? Mr. Musk may have found his funding source after all. Welcome to the dark side!

This guy predicted sing;e stage intercontinental passenger rockets used for commercial as well as troop transport.

Ronald Reagan proposed funding a space plane called the Orient Express that reach any place in the world in 2 hours. It would takeoff and land from a runway. It also could transport cargo to orbit.

It is not exactly a transport that can land in hostile territory so is fairly worthless as a troop transport. DoD has far better options in the here and now.

/Now DoD is interested in cheaper space launch capacity...

yeah, when Phil Bono's book came out  in the 70's, it had depictions of the ssto rocket landing in a Viet Nam-like jungle setting,  showing a line of troops descending a ridiculously high and narrow gangplank to the ground from several stories up.  This in an era when MANPADS were cheap and available. Young me, seeing the artist rendering, thought: looks cool, sure, but you'd have to have a landing zone of many miles completely secured from any ground or air attack to make the landing possible, and one guy with a bazooka or redeye could blow the whole thing up in the final landing phase for a few grand."   And as far as the passenger version, I knew they weren't thinking of regular type tourists that could take three or more gees on either side of a half-hour's worth of zero grav.
