White Knight Two Unveiled
xanthos writes "Sir Richard Branson was at the annual Experimental Aircraft Assoc Fly-in to show off EVE (previously known as White Knight Two), the launch vehicle for Virgin Galactic's commercial space operation. Test flights for the vehicle are slated for next year with the first paying passengers going up in 2011. What surprised me was the following from the article: 'So many people have signed up already, Whitehorn said, that the company has collected $40 million in deposits with orders to build five spaceships to meet the demand.' Will this mean that the $200k price tag may be dropping?"
Expensive, but I would do it if it were for a couple days in orbit...

Space tourism, yeah. But orbital flights?
Why SpaceShipOne Never Did, Never Will, And None Of Its Direct Descendants Ever Will, Orbit The Earth
Will this mean that the $200k price tag may be dropping?
Because everybody knows that when people are trampling each other at the gates to pay the retail price, it's a sure sign that the store is going to lower it in a hurry.
Unless I'm mistaken, I'm pretty sure that the Virgin experience is completely suborbital. Basically it's $200K for a parabolic rocket ride. I don't understand the appeal. OK, so you left Earth's atmosphere for a couple of minutes.
Where's my 2001 space station?
A work that expires before its copyright never enters the public domain and thus enjoys eternal copyright protection.
So, instead of optimizing the vehicle to be just a launch system, they are creating additional revenue by adding in a passenger compartment. "Only $1,000 will get you a window seat where you can watch rich people fly into space!"

But when you return it's the same old place.

Now we're going to end up with Pepsi ads in orbit and hotels on the moon.

Does anybody proofread these submissions at any point?
Will this mean that the $200k price tag may be dropping?
They have more orders than they can fill with a $200k price tag, so why again would they consider dropping the price?

Virgin's FAQ says 200000 is only for the first 100 and then scaling down between 100 and 175K for the remainder of the first 1000 and 20k thereafter.
$40m @ $200k/each is only 200 people. Do they really need 5 additional ships? (Though, they don't say if a deposit is 100% the cost, so it might be more people) And why the hell would you pay $200k for a suborbital flight for a couple minutes?

How is this new news? WhiteKnightTwo was unveiled a year ago. http://www.universetoday.com/2008/07/28/virgin-galactics-whiteknighttwo-sees-sunlight-for-the-first-time-gallery/
Help me fix my brother's injured butt!
There's some pretty cool video of White Knight Two flying at Oshkosh here:
http://www.flightglobal.com/blogs/hyperbola/2009/08/video-all-the-virgin-galactic.html
There's also some notes from a panel discussion on the craft. Some highlights:
* Production run for the program is set up for 12 WhiteKnightTwo carrier aircraft and 50 SpaceShipTwo crafts;
* This is the first all-composites aircraft, something that the aviation industry needs to embrace more;
* WhiteKnightTwo is not just an aircraft, it is a spacecraft delivery system that is capable of delivering cargo into space cheaply; [orbital microsatellite launch]
* Scaled and Virgin are confident they can build a WhiteKnightThree that will allow they to launch even larger payloads into space;
* Rutan said WhiteKnightTwo is very manueverable, and he expected to put the vehicle through aerobatic manuevers at the Oshkosh show next year;
* Whitehorn didnâ(TM)t seem to like this idea very much, vigorously shaking his head and trying to dissuade the designer from such an idea.
How fat can I be and still be able to fly?
>>Cue jokes about Americans.
the first paying passenger's going up in 2011.
That is correct grammar~ In this case, "going up" is a noun, and it refers to the one person who was first. Much like "a send-up".
You will probably quibble at the "first shooting down of the orbitting Pepsi ad" when it is reported.
Unless, of course, the Pepsi ads DO shoot down. Sure, why not. Take the Cola Wars to the Final Frontier. First targets, Atlanta and Plano, TX.
Iirc it was 1964 when Star Trek came out. The science fiction stuff in it was pure fantasy; magic, impossible: cell phones, flat screen computers, doors that opened themselves, medical readouts in the hospitals, etc. It would be five more years before man walked on the moon; orbital flight was in its infancy.
Now it looks like another fantasy will come true - the price of space flight may become affordable to an average guy like me! This is simply amazing.

Can anyone more familiar with the rocket design explain this perplexing quote?
So, does this thing literally burn rubber? :D

So, does this thing literally burn rubber?
Solid fuel compositions tend to be rubbery. This makes them insensitive to vibrations and thermal stresses which could lead to cracking in stiffer compositions. Cracking is a Very Bad Thing as it tends to produce sudden trust variations.
So if by "rubber" you mean "made from the sap of a rubber tree or a similar hydrocarbon synthetic designed primarily for flexibility and resilience", then no, it doesn't burn rubber. The fuel is designed primarily for high specific impulse, with the rubbery characteristics design in secondarily.
The use of a hybrid solid-fuel/fluid-oxidizer design allows the engine to be throttled, and yet is considerably cheaper than a comparably powerful liquid rocket design.

I just got back home from Oshkosh and saw the WK2 up close and personal there at Aeroshell Square. I didn't know beforehand that only the starboard side fuselage pod has any seats for crew. The left side fuselage has fake painted-on "windows" so that it looks like there are real windows from a distance, but apparently the left fuselage only contains equipment and possibly fuel tanks, there are no seats for any occupants on that side.
I took several photos of the center wing section where the spacecraft is supposed to attach. I saw no big heavy-duty attachment brackets there at all, but instead there were bundles of exposed wires only, and there were two cut-off loose wire ends just dangling out in the slipstream.
I did get one good photo of the WK2 in flight as it approached to land, but they did not do any repeated overflights for the crowd to see, I only saw one overflight, then it landed.

Yes and no, it burns hydroxy-terminated polybutadiene (tire rubber) according to this article
Some people at NASA are talking about deorbiting the ISS as early as 2016. This report is probably a red-herring to raise mroe funds from Congress. But some people are thinking about dumping it. Russians think it can last until 2020 or 2030. Partners could pick it up if US drops out.
So if by "rubber" you mean "made from the sap of a rubber tree or a similar hydrocarbon synthetic designed primarily for flexibility and resilience", then no, it doesn't burn rubber. The fuel is designed primarily for high specific impulse, with the rubbery characteristics design in secondarily.
You are wrong, the engine burns rubber (at least synthetic rubber). From http://science.howstuffworks.com/spaceshipone5.htm
"To cut down on both cost and risk, SpaceShipOne is propelled by a mixture of hydroxy-terminated polybutadiene (tire rubber) and nitrous oxide (laughing gas). The rubber acts as the fuel and the laughing gas as the oxidizer."
Enigma
Yes. Truth be told, it doesn't matter what you use as the solid fuel in a hybrid rocket. You can use cardboard, salami, your mom, whatever. Some fuels are certainly better than others, but anything that burns with your oxidizer will work. They're probably using polyethylene or something similar (it's what we used in our college rocket club's hybrid rocket).
Actually, radtea is wrong and Anonymous Coward is correct.
"In our hybrid motor we use Nitrous Oxide (N2O or laughing gas) as an oxidizer and hydroxy-terminated polybutadiene (HTPB or rubber) as the fuel."

The first all composite airplane? Hardly!
Rutan championed moldless composites with the design of the Veri-EZ, and later the Long-EZ and Solitaire. All three planes are all-composite planes, and have been flying for almost 40 years. Spin-offs of the design include the Velocity (www.velocityaircraft.com), the Cozy (http://www.cozyaircraft.com/) and the berkut (now being made and used solely as a UAV for USAF. See http://www.genaero.com/video/Berkut_Autoflight.wmv)
Meanwhile, in the certified world, Diamond Air has been making all composite planes since 1981. IIRC, they built the company using experience from building all-composite gliders. Cirrus announced certification of the SR20 in 1998.
WK and SS1 broke alot of ground, but all-composites is not one of them.
Ya know, back in the olden days, the premier BBS terminal program (think: properly and well-done HyperTerm) on the Mac was Red Ryder. It was such a popular shareware that the guy earned like $5 from it.
Anyway, when he went pro, the Red Ryder people came calling and said he had to change the name. So he changed Red Ryder to White Knight. He then got complaints that White Knight was also a nickname for people in the KKK.
Have times changed? How much more should a huge production like this catch the attention of people.
Oh, and don't argue with me about the validity of the complaint. I'm just relating it.
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
If you look up "hybrid rocket" what you'll see is a lot of similar systems. Traditionally, rockets were either liquid fuel, where you mixed two liquids (oxygen and kerosine, oxygen and hydrogen, for example) or one block of solid fuel like the Thiokol system on the Space Shuttle boosters -- which is, itself, commonly referred to as rubber. A hybrid system uses a solid fuel and a liquid or gaseous oxidizer. Nitrous oxide works well. One interesting thing about it is that you can use just about anything that contains carbon as the solid fuel: rubber, a big stack of paper soaked in wax, or even the infamous Salami Rocket. ("That's what SHE said.") People who build big model rockets often use stacked wax paper discs because they hold up better than salami, and are easier to make than thiokol-type stuff (and they seem to burn more cleanly as well, compared to home-made polymer-type fuels.)
Nostalgia's not what it used to be.

Cheers,
Yes. Watch some more Mythbusters, they built one that burns salami :)
Ok, it was a sucky thing made in a few days with plumbing supplies, but that's mythbuster style, baybay.
You can't take the sky from me...

BURN! :-p

A lot of speculation over the years about this little gem.
So, how much for a one way ticket?
Wish I'd be around to laugh at all the silly people who thought humans mining space was so insignificant it'll never mess with the mass of the planet... When they alter the orbit of the moon or earth and screw the planet with the same idiocy that has prevented progress on global warming even now when a lot of people realize it is a problem.

I stand corrected (although what I said is true of most solid booster compositions!) /. needs a "-5 I was wrong" mod!
Blasphemy is a human right. Blasphemophobia kills.
Actually what happened was that the Bush administration directed NASA to focus on a new mission -- returning to the Moon, and sending Astronauts to Mars (and also directed NASA to retire the shuttle) -- but did not provide NASA with the additional promised funding. NASA, therefore, in order to try to meet those mission goals within the projected funding levels, decided to retire ISS earlier than originally planned. I hope that the new administration fixes this problem. ISS is a marvelous research platform, and if we de-orbit it in 2016, we're going to wind up needing to build another one at a later time.

Mod this guy up. It does burn rubber. The parent is wrong.
Branson has said he's naming it EVE. Until he takes possession of it, the name remains WhiteKnight Two.
WhiteKnight Two was "unveiled" (called a roll-out) on July 28, 2008. It has been seen flying at Mojave several times since. It's first outside public appearance was at the groundbreaking ceremony for Spaceport America June 18, 2009.
The EAA function is called AirVenture. The name was changed in 1998.
WhiteKight Two has been undergoing flight testing since its first flight on December 21, 2008 (this ironically taken from the EAA News). Flight testing of Spaceship Two is scheduled for later this year.
That's the problem with grabbing something off the Firehose and not looking into any of the details before submitting it.
Nothing here states why WhiteKnight Two was taken to Oshkosh. It wasn't so the attendees could gawk at it or because Virgin Galactic needed the ticket sales. A pending submission covers this so I'll hold back and see how that turns out.
