> We are excited to announce that SpaceX has been approached to fly two private citizens on a trip around the moon late next year. They have already paid a significant deposit to do a moon mission. Can't wait to hear who booked this trip! Definitely one of the coolest ways to spend a lot of superfluous money :)

What if it's Larry Ellison and Travis Kalanick?

Wow. This sends so many thoughts cascading through my head that I'm dizzy. Some things to consider, China has been working up to getting a space capability to send people to the Moon with the full backing of the government funding, by 2035[1]. They started in 2003. SpaceX was founded in 2002 and they are saying they will fly someone around the moon next year? Dragon has the deltaV to land on the moon (not sure if it…

> The next person to take a picture of the Earth from moon may not be on a government funded mission. Note that the press release says: 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. Your tax dollars, if you are American, helped pay for this. Thank yo…

As a taxpayer (who was just reminded this past weekend of how much that is :-) I'm really glad that NASA had enough budget to spend on the Commercial Crew program. Given that the NASA budget of $18.5B[1] is a rounding error on the overall budget $3,540B[2], seriously it's a half a percent. And commercial crew was only $1.2B [ibid] of that NASA budget. So less than .05%. Again rounding error.

And with that money they are getting two different spacecraft that can fly missions. So I think it was a great way for NASA to contract out the development of a crew capsule they could use on their missions.

That one of the companies that participated has done so in such a way that they can make a commercially feasible 'tourist' vehicle out of it? That blows my mind.

At least it'll be nice to have them off the planet for a couple of weeks.

In the same way that hitting a stuck bolt with a hammer is a strategy. It applies pressure sure, but you break your tools and the nut gets stripped. It seems to a preferred motivation method though.

It worked before. Kennedy's moon shot speech was 8 years and 2 months before Apollo 11 landed on the moon. The speech was made before the US had put a person in orbit. https://www.youtube.com/watch?v=0T1ztqhYQ7g

Of course, that time around it lead to the Apollo 1 fire killing the first crew in on-the-ground testing before they even got as far as trying to launch them into Earth orbit. Probably not something to be looked up to.

Well there's a huge difference when talking about radiation exposures going to the moon and Mars. For one you don't expect a solar event to happen, you really hope one doesn't, when going to the moon. Going to Mars you expect a few. With cosmic radiation we're talking about the difference between a few days and a year. Plus you have to have pretty good shielding when crossing the Van Allen belts. You can consider the…

I'm less worried about this mission, and more than it's going to give people an (increasingly) false confidence that we're ready for Mars.

Ah, in that context, yes. We'll have to see a lot about the flight performance of the Heavy and whatever crew capsule they come up with. I would imagine they would do it similar to how the Apollo missions were done. First you do the dress rehearsal where no one lands. They could use that mission to put supplies in orbit as well. For Mars, they might need more than one. I'll be interested in what they come up with, but I still think their goal of 2025 is pretty quick. Doable, but I wouldn't hold my breath.

The two private citizens will need a support team in capsule unless they are experienced astronauts and have the technical skills to learn all the systems on the dragon crew capsule.

Do you have a source stating that the people crewing the Dragon would need to do anything at all? Won't it just be on autopilot, what duties is the crew of the capsule expected to perform?

If something bad happens, you don't want to say "oh well, guess I should have sent an expert with them after all."

Ok, let's put it like this: how much are you willing to bet that they'll be sending two passengers around the Moon on board of Falcon Heavy/ Dragon 2 next year?

Plus they've had 2 rockets go explody over the last two years. This is really premature. I'd be surprised if they do this by 2020.

One was a ground incident that wouldn't have had people nearby even with a manned mission, and the other would have saved its passengers with the abort system.

And if people are willing to pay the money and take the risk, why not?

A quote from an article on the Verge says "Musk declined to comment on the exact cost of the trip, but said it was “comparable” or a little more than the cost of a crewed mission to the International Space Station." Does anyone have a rough estimate how much a manned mission to the ISS currently costs?

For perspective, it cost about $200 million to get your name on an America's Cup trophy. So as billionaire vanity projects go, this is pretty reasonable.

I know for a fact that NASA is still concerned about that Helium tank.

The explosion from that helium tank was slower than the emergency rockets on the dragon, from what I understand. So, had the capsule been fitted with them, it would have stayed entirely clear of the event. It'd be a rough ride, but it would have been a survivable event.

The thing is that NASA doesn't want to put anyone on something has the chance of doing that. The emergency system is for emergencies. Ideally it should NEVER be used. Vetting for manned missions is a lot different than cargo. That's all I'm getting at here. When rockets have recently exploded NASA gets pretty worried about putting humans on it.
