X-51A Waverider
Click here to view the embedded video.
The X-51A Waverider built by Pratt & Whitney Rocketdyne set a record for the longest supersonic combustion ramjet-powered flight in late May eclipsing the previous record of 12 seconds by the NASA X-43A, although the X-43A was almost twice as fast.
The flight was a bit more than 200 seconds and the X-51A accelerated to Mach 5. March 5 is about 3,800 mph or 6,155 kmh. The flight was short of the 300 second burn and Mach 6 target because the vehicle began to slow once it hit Mach 5 and apparently there was some unexpected heating in the rear of the engine bay detected and the vehicle was destroyed by its operators. That said, the flight was a success.
The scramjet’s claim to fame (one of them anyway) is that it can operate at hypersonic speed and pull oxygen out of the rarified atmosphere at high altitudes so it doesn’t need to carry an onboard oxygen supply. The scramjet engine has no moving parts so as long as it has fuel it can operate, the problem is the engine has to be going very fast in order to work.
What you are seeing in the video isn’t necessarily the result of the scamjet engine, especially at the start. In the video the vehicle is dropped from the B-52 at 50,000 feet and a solid rocket motor accelerates the vehicle to almost Mach 5 and it is at this point where ethylene is used to start the scramjet engine and a transition is made to JP-7 aviation fuel.

Is SETI a Waste of Time?

A brief Virgin (and TSC) update
Enrico Palermo of Virgin Galactic discusses the company's development of SpaceShipTwo and WhiteKnightTwo at the NewSpace 2010 conference on Saturday.
At the end of Saturday’s sessions at the NewSpace 2010 conference in Silicon Valley, Enrico Palermo, project engineering manager for Virgin Galactic, gave a brief update on the company’s activities. There weren’t any new announcements about the company’s efforts, nor (consistent with their past practices) predictions about future flights. Palermo did show video of their most recent captive carry flight, the first time a crew flew in SpaceShipTwo, as well as some new photos of work on SpaceShipTwo in Scaled’s facilities, showing the spaceplane’s wings rotated up in the feathering position that provides for the “carefree” reentry of the vehicle, in much the same way as SpaceShipOne.
Palermo did provide a few updated statistics about the company and the vehicle testing program. WhiteKnightTwo now has over 100 hours of flight time on 33 flights since the test flight program began in late 2008. SpaceShipTwo, meanwhile, has now flown three captive cary flights. On the business side, the company now has over 350 customers who have paid deposits ranging from $20,000 to the full $200,000, with a total of now over $50 million. Those deposits, he added, are held in escrow for now, and won’t be converted to company revenue until the tickets are formally issued.
Palermo also briefly discussed The Spaceship Company (TSC), the joint venture between Virgin Galactic and Scaled Composites that will manufacture the WK2 aircraft and SS2 spaceplanes. “This is a company you’re going to be hearing a lot more about over the next year or so,” he said. “We’re currently assembling a team of individuals to run TSC in Mojave; we’re recruiting like mad.” (There is a list of job openings on the TSC web site.) TSC is currently located in an existing building at Mojave Air and Space Port, but Palermo said there are plans to build a new final assembly hangar there.
My First Kiss | The Intersection
Several readers have written asking why I’ve been so slow about updating the kissing gallery. Chalk it up to a busy summer and my wedding in two weeks. But thanks for so many great submissions to my inbox! I’ll be sure to get some of the best posted here soon.
In the meantime, a music video: Here’s 3OH!3’s My First Kiss featuring Ke$ha. As I detail in my upcoming book The Science of Kissing, that very first romantic kiss with a new partner can make all the difference between a fleeting encounter or lifetime commitment…
Submit your original photo or artwork for consideration in the gallery. The more creative, the better.

Comic Con 2: SMBC and me | Bad Astronomy
I have no real news here, except that one of my missions at Comic Con was to meet up once again with Zach Weiner, who writes and draws my favorite web comic, Saturday Morning Breakfast Cereal. My wife and I went over to his booth, and there he was! As this picture shows, I was overjoyed to see him:
While we were chatting and mutually insulting/praising each other, who should walk up but blogger, actor and all around good-guy Wil Wheaton! I was shunted aside, but managed to make my presence known:
Anyway, you should go read Zach’s comic and buy his stuff and support him in his attempts to take over the galaxy. Don’t forget to click the red button.
