Amazingly cool! Privately funded space travel should be the future, as opposed to the mostly self-serving bureaucracy that is NASA.

BINGO!!

There are few things the government can do, that the private sector cannot do better, cheaper, and faster.
 
This means cheaper flights for the tourists to go up into space!~ Finally people like Lance Bass will be able to afford going into space!
 
Very Cool, Rutan is a god!

Just remember folks, altitude != orbit
This is about the equivalent of Mercury 3, the first US manned space flight in 1961. Although Mercury 3 reached about twice the altitude.

Still, it's a big step for private spaceflight.

Certainly costs less, especially when you consider that the true cost of Mercury would have to include the cost of the entire US strategic rocket program. It's not so hard to be cheaper 40 years later, standing on the shoulders of giants, and not subject to the kind of beuarocracy that a government agency is.

Safer is tough to judge, as all 6 Mercury flights were successful.

Please understand that I'm not trying to belittle this accomplishment, but we're still a long way from private industry replacing NASA.

Does spaceshipone plan on getting to the moon in 8 years, with the same general design? That was part of the point of NASA. Also we didn't know what would happen in space. It's like comparing the X-1 to a B-1a bomer. Both could break the sound barrier but look what the X-1 needed to get there.

hmm what do 3-4Gs feel like in terms of pull ? Is the max for a human @ 8Gs ?

You can get 3-4Gs on a 'hardcore' roller coaster. I forget which ones, but there are a few that reach to at least 3Gs. And humans can withstand up to like 12-14Gs before dying. Most people start to pass out between 6 & 8 (i think) without some sort of g-suit (like what pilots wear).

Actually, 10 million. And they have to do it twice within two weeks. They said this was not part of that attempt.

Really? My mistake. I was reading all the Popular Science articles about them (seemed like it was in 2-3 issues in a row).

I am surprised it's not part of the attempt. Why not? (Not questioning you, asking for more info)

Thanks for the clarification.

g-suit? any more info on it (like how it works) ... yeah too lazy for a google search and yes it's a serious question.

But not too damn lazy to create a post that took longer than a Google? :roll:

Are there any Gs on a freefall because I feel like my heart is coming out of my ribcage during them...

g-suit ... AKA speed-jeans.
It's a device that inflate to put pressure on your legs & lower abdomen to help keep blood in your head so you can sustain more acceleration. Used by fighter pilots, because most of the acceleration they will get will be pushing them down into their seat, so the blood wants to leave the head, and go south.

As for g tolerance ... varies by person & training, and there is a big difference between instantaneous & sustained g forces. There was an interesting article I saw a few months back about human decelleration trials using rocket sleds ... they reached some phenomenal numbers, various collisions do also. But this isn't sustained stuff where you have to keep functioning also, like flying a plane.

I think the generally accepted limits are 7-8 sustained (up to 20-30 seconds?) g's for someone with the proper training & equipment. If eaglekeeper shows up, he can probably give a more definative discussion.

Also saw something awhile back about long-term sustained g's, like days/weeks/months for something like a Mars expedition. IIRC, some of the data suggested that even 1.5g's may not be possible for that kind of situation.
