Musk said 400,000 miles.

Others can speculate if he meant km and the velocities for each.

The context indicates miles, since in the same sentence he also reference the distance to the moon being 250k IIRC.

An article about an actual space tourist and their recommendations for the circumlunar travelers:

Travel Tips From a Real Space Tourist: Get Ready to Feel Awful - Bloomberg

An interesting passage:

"...says Garriott de Cayeux. “There’s a disagreement between what you see that you’re doing and what your body thinks it’s doing—and that often causes sea sickness.”

That perceptual disconnect tends to last for about three days before your brain begins compensating."

So about half the trip you're still trying to get acclimated to space.

A good reason to consider a 5 minute jaunt into weightlessness - see how badly space-sick you become.

I actually don't think this would put many potential customers off. Humans are willing to put up with a LOT of discomfort if it's in the name of "fun". Ask anybody who enjoys backpacking!

EDIT: I just read the bit about him voluntarily having a lobe of his liver surgically removed... okay, not as many people would go THAT far...

I enjoy backpacking, but personally I would never do scuba diving due to the issues related to what happens if I have to cough or hiccup while under water (that's just me of course). So I'm not sure that once someone finds out all of the things they have to train for (even as a "passenger") that there would still be a big pool of high-wealth individuals that would want to do this type of trip.

And I'm glad you pointed out that part of the article where the guy had to have surgery to pre-empt the chances of a medical emergency while in space. That just goes to show that travel in space is not yet for the average person.

I'll take them up flying with me and do some parabolic flights, some stalls, throw in some spins and then see if they turn green...

You worry too much
(Coughing, sneezing, or hiccups underwater? Not a real problem from my first hand experience)
Everyone who has gone to the ISS speaks glowingly and one of the "tourists" went twice.
Thousands of people do parabolic flights to get half minute periods of weightlessness and they experience discomfort and need heavy medication.
Long lines will form.

And where did Garriott's "de Cayeaux" come from?!?

From Wikipedia: In 2011 he was married and changed his name to Richard Garriott de Cayeux.

So: From his wife.

What do you mean turn green? That's the fun part of flying.

Adam Savage, as I recall, was instructed that it's best to eat bananas, since they taste about the same coming up as they do going down. I, on the other hand, can attest to the inadvisability of eating an Egg McMuffin before a scuba-diving boat trip. As much as I wanted to go to space when I was a kid, I'll probably have to wait for CERN to come up with artificial gravity.

I could eat about anything, cast iron stomach, but drinks were another matter. My kryptonite was orange juice. Right up the nose....Yeetch.

Hey, guys... I've finished my story dramatizing a notional Dragon manned Circumlunar flight. I worked on it for a week and drafted, tidied and edited it till I could no longer stand to look at it. Any typos or errors are all mine and all regrettable. It's not perfect, but I hope you enjoy it anyway.

EDIT - I found a couple rather annoying errors in the text that I have now fixed. Anyone who has already downloaded the story - if it's not too much trouble; please delete the previous version and take this one instead!

If anyone would prefer I upload a version that presents as Times New Roman font; let me know. But I prefer Arial font as I feel it's easier on the eyes. Regards; Matt.

Hi Matt.. it took you only a week to write that? I didn't read it yet but wow.. 27 pages, thats like 4 to 5 pages a day constantly. I never got beyond 4 pages during my thesis and never hold up that pace for more than two days. And the reason was not that the topic was difficult (it wasn't for me at the time of writing). Its just hard for me to write in any acceptable quality faster than 3 pages a day. Looking forwards to read it

No time to read the whole thing now, but it's SpaceX, not Space X.

EDIT: Thanks to my fellow Welsh Dragon (I have ancestry there) I have just revised this one more time to change to the correct 'SpaceX'. Heh - Everyone feel free to once more delete the previous versions. Terribly sorry - it was my failure to spot other errors the last times that prompted me to quickly re-write - but I missed this. The reason for the incorrect spacing of SpaceX? You have to override the 'wishes' of the spellcheck, otherwise at 4:30 in the morning when you make the 'final' draft; chances are you'll be too punchy to notice that the spellcheck has incorrectly changed it...

I wonder if sailing for a week prior to launch would help. Usually it takes me also 3 days to get my sea legs...

I think so. Other research has shown that you can help your inner ear adapt with certain strategies.

Or they'll find out that you can be simultaneously both sea sick and space sick.
