A year or so ago the Tesla sedan with Ludicrous Option did 0 to 60 in 2.8 seconds. I think there's a faster one now. Also up to 360 miles or so on a charge. Enough there to break Earth's gravitational pull! Go for it!

In another article, it was stated that the price being paid has not been disclosed, but is probably equivalent to what the Russians charge for a civilian seat on a Soyuz up to the ISS. About 7-8 years ago, that ride was costing $22 Million, but the Russians now want $80 Million apiece to fly our astronauts to the ISS.

Pretty much says everything that's wrong with capitalism unrestrained by appropriate government oversight and a near total lack of concern for society at large. As a nation and society you know you have your priorities in order when you spend a several hundred million dollars sending a couple of clowns to the moon while our education system suffers enormous student / teacher ratios, most families are one serious illness away from economic ruin, and our national infrastructure is in tatters.
But at least there's an easy fix - up military spending ten percent for completely unknown reasons and slash domestic spending. Yeah, that's the fix.

healyje, should we shut down Hollywood, except for producing documentaries?
The money spent will be for many good paying jobs. Yes, we need to get our priorities in much better alignment. Fix what is bad but don't sell this type of progress as bad, otherwise what is the point of improving our education?
A better future for our students will start with an idea, hope or dream.
I don't begrudge those that make their money from innovation or entertainment. Those that make fortunes off the the backs of others, such as Wells Fargo type bankers or the epi-pen patent producers who jacked up the price because people needed their product to live, should be scrubbing toilets and floors at our schools and prisons, for community service.

We all just paid for a couple rich f*#ks to fly around the moon while Elon Musk makes a nice tidy profit. This country is f*#ked in the head. I seriously hope that capsule suffers a depressurization in the deep cold darkness of space.
From the Space X press release-
"Most importantly, we would like to thank NASA, without whom this would not be possible. NASA’s Commercial Crew Program, which provided most of the funding for Dragon 2 development, is a key enabler for this mission."

I have a more historical viewpoint on this. Much of the progress in the early days of aviation was made by philanthropic prizes to "winners" of various trophies in competitions. Almost all the accomplishments were spurred by that old demon: Money. Glenn Curtiss built many of his innovative airplanes to win cash prizes. Lindbergh flew across the Atlantic solo--for a cash prize. The "2 clowns going around the Moon," may be doing it for a much more altruistic reason than just having fun. They are just getting something for their contribution to society in general. This certainly has the "blessing" of NASA, at least according to their press releases, anyway. It's just playing a game with higher stakes than most of us can afford. I'm sure that were Howard Hughes still alive, he's be involved with it, too.
Edit: In response to Slabby D: The Dragon spacecraft was built for a NASA contract to haul astronauts to and from the ISS. This was a fixed price contract, and not one of the sleazy "cost-plus" deals normally awarded the "big boys." Fixed price. This essentially saves NASA $160 Million for a crew change each flight accomplished to ISS, and is the only way back for many of the science experiments. We the people age getting more return on our dollars this way BEFORE SpaceX utilizes the technology THEY developed to make a few bucks.

Assuming that a gravity slingshot maneuver is planned - much the most energy/weight efficient - the spacecraft can't go much further past the moon than did the Apollo missions, that is 100 - 200 km. Going into orbit around the moon, and then returning to Earth, would be a greater challenge.
For future longer-duration space missions, will the tendency be to select humans who are smaller/lighter, on the basis that they require less food, water, and oxygen, and so less mass? This would probably exclude both Greg and me.

I get it.
Space exploration isn't just about adventure (although that should be enough for climbers to value it), it's about contributing to our understanding of the universe and creating new technology that filters down to everyday life.
Computers would be decades behind where they are now without the space program. And that's just one example. Materials. Communications. etc.
Then there's the environmental and atmospheric science.
SpaceX is figuring out how to build rockets that will save the US taxpayer money to get astronauts and cargo into space. They have a contract to fly cargo and people to the ISS. They will use the tech developed for that for this moon trip. The taxpayer isn't paying for the trip.
So some rich guys get to have an awesome adventure. People complain. Then they drive their cars to go climbing. Shouldn't they be donating their gas money to underprivileged people? Or is it fine to spend $50 climbing, but spending $100 million is morally wrong? That's like saying a $50 prostitute is fine, but a $1000 hooker is immoral.

Regarding Van Allen belt radiation; the Earth to Moon departure screams through VAB in minutes when doing 20,000 mph or thereabouts. That's primarily alpha particle radiation, from which the body can easily recover/repair itself.
Bone decalcification won't be an issue, since this flight will take around 9 days round trip.
Incidentally, I'm now working on a SBIR solicitation for bone decalcification studies, and NASA has asked for proposals.

Anders-
This mission is simply a free return trajectory just beyond the moon, and no orbit is included. It should be a wild ride! The amount of money being charged should allow SpaceX to complete development of the Dragon 2 capsule with NO more NASA funds involved.
SpaceX charges $98 Million for a Falcon Heavy launch, which is what this will be. It's a win-win-win for SpaceX, the 2 pioneers, and yes, the U.S. Taxpayers.
SpaceX is leasing their launch pads at Cape Canaveral, which goes to the U.S. Treasury.

As an addendum-
The trajectory is planned to take these guys 400,000 miles from Earth, so they'll have the first view of the Earth and Moon from the farthest man has flown from Earth,; what a sight that would be. So--they'll see the moon about the size we do AGAINST the Earth as the backdrop. Wow! Only $80 Million to be the first to see that?

the Fet: thanks for making that argument better than i would have.
considering that some of the other options for those with 88 million [or whatever the amount was] burning a hole in their pocket, includes super yachts, penthouses atop phallic towers, and all of the hookers and blow for a lifetime, i can't say i really understand the hate being sent towards those funding a space program and getting a front row seat along the way.
sure they could have donated it to the fight for cancer or some such, but i gotta admit i'm not sure which i find more disgusting: 88 million westerners eating an extra patty on a cheeseburger sometime this week or some dude/tte spending 88 million on funding a space program and getting preferred seating.

Well, you could send out a camera, instead.
But I do not intend to cast aspersions. Quite the opposite.
These 2 people should pay a little more and land on the Moon. If they want to pay to get back, too, well that's okay, but I hear that there are people willing to go one way to Mars, so why not the Moon?
It could make good programming. Here they are in their dome, trying to grow hydroponic tomatoes, prospecting for water, thinking up ways to kill each other. It could be poignant, poetic, helpful to manned space exploration, and karmic payback for Laika.
Okay, enough fun. I respect Rodger.

A few more details have surfaced. There will be an unmanned flight first as a proof of concept and as a test of equipment. The price is actually closer to $35 Million per person. So...Moose! If you can get $100 Million, we can BOTH go and spend the rest on wine. Close quarters in the capsule, though. Do you fart a lot?

I have HUGE respect for Elon Musk, but i am afraid that this may be an overreach. This trip is like free soloing El Cap. Granted that there is less training and skills, but if ANYTHING goes wrong, there will be a nasty splatter and a huge public relations disaster. If the human race is ever to really get into space for real, risks must be taken, and people WILL die, just as in the beginnings of aviation. But chucking rich tourists into space and listening to them slowly expire when the engine fails and they cannot make earth orbit again will NOT help the cause.
I have, over the years, become rather frustrated with NASA, but there is something to be said for a careful, systematic approach. I really hope this does not go bad, as SpaceX and their ambitions and drive is a bright light in a world sometimes filled with darkness and misery.

This is going to be quite a simple mission profile. There will be no engine burns required after the launch. The Falcon Heavy will fire the capsule beyond the Moon, but not fast enough to escape Earth gravity, so it will come back down and re enter the atmosphere as it was designed to do. So...would I go? Yep. This is about as simple as a space launch can get. Meanwhile the 2 astronauts will have the ride of their lifetimes.

Funny. I misread the thread title every time.
SpaceX to send privately screwed spacecraft beyond moon.
But seriously, I hope for a safe ride and return for those on board.
A question for the rocket scientists here: Is it really a good idea to strap three rockets together, with a total of 27 liquid fueled engines? To the lay person this looks like a large risk for failure. What happens if one of the twenty seven craps out?

Engine redundancy is part of the safety planning; a single engine failure occurred once before and the spacecraft still was able to achieve orbit through extended burn time. There's a climb at JTree called Safety in Numbers, I seem to recall?

We all just paid for a couple rich f*#ks to fly around the moon while Elon Musk makes a nice tidy profit. This country is f*#ked in the head. I seriously hope that capsule suffers a depressurization in the deep cold darkness of space.
This kind of whining completely misses the significance of what SpaceX is trying to do. If we waited for NASA to push the boundary of space exploration to the next level, we're talking about a time scale of decades. Elon Musk has the vision of putting people on Mars in a matter of a few years. Whether or not this is a good idea is one question, but I don't understand all the hating going on towards SpaceX.
Personally, I am a big fan of Elon Musk. He sets goals that members of the status quo call unrealistic, pursues them with (mostly) his own money, and achieves the "unrealistic" goals a surprising amount of the time. Yes, he takes huge risks, but that is what is required to push the envelope for any serious pursuit.
I couldn't afford to take this ride, and I'm not sure it would be within my tolerance for risk anyway. What SpaceX has done and is doing is truly amazing, and the fact is Elon Musk is pushing boundaries like this in a wide range of industries.

Maybe he can solve his companies debt problem by crewing the first round the moon shot with the creditors.
Just a thought.
Actually I can get past my disdain for his sucking off the public teat by huge respect for the frontiers he's pushing.

I have say that *We* didn't pay for it as taxpayers underwriting the mission. The only $$$ SpaceX received from the *Public Teat* was through a contract granted to them for services ALREADY RENDERED! The ISS Resupply missions is what they are getting from NASA.

a single engine failure occurred once before and the spacecraft still was able to achieve orbit through extended burn time.
I certainly hope that should one fail you are right. Again, a layman here, but doesn't the precision required to achieve that perfect lunar orbit which will then send them exactly to their re-entry window a bit trickier than achieving earth orbit?
Would they be able to compensate for a failure of one of the outside rocket engines, far out left or right?
I'm playing devil's advocate. Hopefully everything will go according to plan.

I was referring to his Tesla and First Solar companies Brokedown, not SpaceX.
If Nasa could send 8 missions, including the crippled 13 with the prehistoric equipment and computers of the 60's, I'm sure Musk can easily do it with today's technology. The Falcon Heavy's lack of adequate testing is a little worrisome though. Wouldn't want to be the first mission.

The Falcon Heavy is designed with lots of overkill, and they could conceivably lose up to 3 engines and still carry out the mission. They are mounted on gimbals so the thrust can be vectored to compensate for an engine out problem. There will be no attempt to go into lunar orbit on the flight. Just a simple ballistic return The actual flight path I've seen in the diagrams is sorta' a big figure 8 because ot the distance to moon moves in it's orbit during flight time.

Sorry, that's what I meant, a slingshot around the moon. So on the return their target is rotating and moving through space. How big is their re-entry window? Again as a layman this sounds pretty hairball.
NASA did it several times with much cruder equipment, so I suppose it's a reasonable assumption. But they also practiced the whole launch thing with heavy rockets a lot more. Saturn V never had a failure unless you count that horrible fire in the spacecraft while they were on the pad as a failure... not really the rocket's fault.

This stuff fascinates me because I started out in college in Aerospace Engineering, but later switched to Chemistry. Yeah, I can still do some of the analytical mechanics involved It's really a 3 body problem that needs computer solution--not pencil and paper. This wouldn't be that trivial with the computational equipment from Apollo days.
Ol' Elon is getting me inspired--maybe my next car will be a Tesla?

Hahaha! A Tesla in Wyoming. Sounds like the start of a B grade horror movie!

I have an old buddy who used to work for NASA on smaller orbital vehicles. Satellite launches and the like. He's really fast with a slide rule.

Just for Rodger, jogill, Rich, jstan, and others:
My father in front of a display of slide rules he made for his engineering classes' 50th anniversary reunion. One slide rule for each student - he collected them at rummage, garage, and other sales. It's now hanging at the University of Saskatchewan.
But I wouldn't let him have my trusty Napier's Bones.
Werner: I still have a round slide rule.

When I was in college I had the round one up on that board ......
I still have my lab notes from those days.
If I still have my round one I'll post its photo here.
