![]() ![]() BY SPACEFLIGHT NOW ![]() Look back to the first X Prize launch of SpaceShipOne with our status center coverage as it appeared live on Sept. 29.
WEDNESDAY, SEPTEMBER 29, 2004
1848 GMT (2:48 p.m. EDT) "It was a comfortable, easy flight. The flight, for me, was great. I came off the hooks (from the White Knight carrier aircraft), started the engine, the engine started up just like clockwork, starting pulling back on the stick, trimming a little bit, and the airplane just went straight up. I couldn't believe how straight it was going. Last time I was all over the sky, and most of that was my own fault. I hate to say that, I actually made a mistake there. I got into it in the yaw-trim system and I got into a PIO (Pilot-Induced Oscillation) and all of that rolling you might have seen on the last flight (in June) was entirely me and not the vehicle. "This time you didn't see any of that because I figured out the problem and fixed it. So it made a very nice, straight trajectory to the top. Then at the top we got a little bit of rolling motion going but I think it looks good for the crowd if you can roll at the top of the climb," he said prompting laughter in the audience. "I think we did about 20 turns in roll and there were some pretty high rates there. But Burt has designed a system that allowed me to stop the rates. I turned on the reaction jets and I stopped the rates, brought it to a complete standstill in space. I even had time to pick up a still camera and take some pictures out of the window. "And then (I) prepared the airplane for the descent and came back in and made a decent landing. And thank heavens for the the good weather. It was great. "I hope you all enjoyed it. I sure enjoyed the ride."
1848 GMT (2:48 p.m. EDT) "This is not going to affect the second attempt at all. The vehicle is ready to go. It won't take us but a day or two to put it together."
1840 GMT (2:40 p.m. EDT) "Part of it is the speed. You are going at a tremendous speed and if you put any kind of a roll into it, it is going to ramp up very fast. But the roll rate was very controllable. I stopped the roll rate just using the normal controls of the airplane. "I'm not sure what kicked it off. But I'm sure that when we know what it is we will tell everybody what it was. It was probably something that I did. I didn't think it was me last time. But boy when we looked at the data, there it was as big as life. "So I'm inclined it is something I did. But I never felt uncomfortable. "And I actually think it helped us," he continued with a smile. "We were spin-stabilized and we managed to keep the trajectory going -- we were perfectly on course. I'm very, very pleased at how it went."
1834 GMT (2:34 p.m. EDT) "I don't think I made a mistake. Bear in mind we haven't be able to look closely at the data. We took a real quick look at and none of us are positive what caused that. It is possible that I stepped on a rudder when I shouldn't have. You get older you can do things like that. We will have to look and see what that was. "It was at no time any worry for me. I knew the rates could be handled. I was very glad to see that I passed the altitude (62-mile threshold for X Prize) and I waited a little bit longer just to get a little altitude in hand and then I shut (the engine) down 11 seconds early. I had 11 seconds more of burn -- I could have gone to 360,000 feet today -- but I didn't think it was worth taking that kind of risk because we have a second flight to do. It is better to get the altitude, bring it back clean and undamaged."
1710 GMT (1:10 p.m. EDT) From the time of White Knight separation to touchdown on the runway, SpaceShipOne completed a free flight last a few seconds over 24 minutes, equaling the time spent on the June test launch.
1620 GMT (12:20 p.m. EDT) Burt Rutan says the data will be examined closely, but at this point officials expect to conduct the second X Prize launch attempt within the next two weeks as required for the contest. Melvill quipped that the craft just needs to be refueled and it'll be ready to go.

1435 GMT (10:35 a.m. EDT) This twin-engine turbojet craft made its first flight in August 2002. In addition to being the mothership to launch SpaceShipOne today, the White Knight's flying characteristics -- thrust-to-weight ratio and speed brakes -- allow it to be used as a flight simulator for SpaceShipOne pilot training.
1425 GMT (10:25 a.m. EDT) The engine will burn for approximately 80 seconds, propelling the spacecraft at least 62 miles above Earth for today's suborbital spaceflight. SpaceShipOne is powered by a hybrid rocket motor. The innovative engine uses a solid, rubbery hydroxy-terminated polybutadiene propellant and nitrous oxide laughing gas as the oxidizer. Both are safe to handle and the oxidizer is self-pressurizing at room temperature, allowing SpaceShipOne to avoid the use of complicating turbopumps.

1235 GMT (8:35 a.m. EDT) "Futron worked very hard over the course of several months to objectively and accurately analyze the space tourism market," said Phil McAlister, director of Futron's Space & Telecommunications Division. "We hope that our efforts, as captured in this report, will benefit the many people interested in this promising market." Highlights of the study include:
1155 GMT (7:55 a.m. EDT) The 63-year-old test pilot earned his astronaut wings during the June 21 launch that reached 62 miles -- widely considered to the edge of space. SpaceShipOne is expected to go at least that high today.
TUESDAY, SEPTEMBER 28, 2004 The craft was loaded with its oxidizer fuel Tuesday, and weather forecasters are predicting favorable conditions for Wednesday's voyage. The White Knight carrier aircraft with the SpaceShipOne craft mounted to its belly will taxi to the runway at California's Mojave airport at 6:30 a.m. local time (9:30 a.m. EDT; 1330 GMT). The duo is expected to be airborne around 6:45 a.m. PDT (9:45 a.m. EDT; 1345 GMT). It will take about an hour for White Knight to reach an altitude of nearly 50,000 feet where SpaceShipOne is dropped at 7:45 a.m. PDT (10:45 a.m. EDT; 1445 GMT) to ignite its rocket engine and blast to the fringes of space. After a powered flight of about 80 seconds, SpaceShipOne will coast up to an altitude in excess of 62 miles then reenter the atmosphere and glide to a landing on the Mojave runway by 8:30 a.m. PDT (11:30 a.m. EDT; 1530 GMT) to complete the brief suborbital trip. The man who will pilot SpaceShipOne remains a secret. His identity will be revealed Wednesday morning. SpaceShipOne was created by Burt Rutan and funded by Microsoft billionaire Paul G. Allen. It flew a similar flight in June that served as a full-scale rehearsal for two launches needed to win the X Prize. The contest aims to promote private spaceflights and space tourism. Teams must design a spacecraft and launch a human into space, then repeat the flight within a two-week period. If Wednesday's flight goes well, the Rutan team hopes to launch again October 4 to claim the $10 million prize. The SpaceShipOne project has been well in front of competing teams. A Canadian rival had planned a launch in the coming days but has since scrubbed the attempt. While claiming the X Prize remains the near-term goal, Richard Branson has signed a deal to use the SpaceShipOne technologies to develop the world's first privately funded spacecraft dedicated to carrying commercial passengers on spaceflights. Branson's Virgin Group has formed Virgin Galactic -- a new company that plans to be become the first commercial space tourism operator. "We've always had a dream of developing a space tourism business and Paul Allen's vision, combined with Burt Rutan's technological brilliance, have brought that dream a step closer to reality. The deals with both their companies, being announced (Monday), are just the start of what we believe will be a new era in the history of mankind, making the affordable exploration of space by human beings real," Branson said. "We hope to create thousands of astronauts over the next few years and bring alive their dream of seeing the majestic beauty of our planet from above, the stars in all their glory and the amazing sensation of weightlessness. The development will also allow every country in the world to have their own astronauts rather than the privileged few." Virgin Galactic will open for business by the beginning of 2005 and subject to the necessary safety and regulatory approvals begin operating flights from 2007, the group said in a press announcement. "It is expected that around $100 million will be invested in developing the new generation of spaceships and ground infrastructure required to operate a suborbital space tourism experience. Over five years Virgin expects to create around 3,000 astronauts and the price per seat on each flight, which will include at least three days of pre-flight training, are expected to start at around $190,000," the announcement read. "Virgin will reinvest the proceeds in developing a new generation of vehicles for further space ventures. To date the cheapest space tourism experiences in government built and taxpayer funded spaceships cost over $15,000,000 per seat." "I backed the development of SpaceShipOne because I saw this as a great opportunity to demonstrate that space exploration could someday be within the reach of private citizens," Allen said. "Today's deal with Virgin represents the next stage in the evolution of the SpaceShipOne concept, and will likely be the first of a number of deals that will utilize the technology developed during its creation. I am very happy to have Virgin and Richard Branson as sponsors of our X Prize attempt and excited about space tourism." "Our June space flight was flown with several new technologies that address both the cost and safety of manned spaceflight. These, combined with the lessons learned from our SpaceShipOne research program, will enable us to develop the finest suborbital operational systems possible," Rutan added. "I am looking forward to getting started on the development program and the opportunity to work with Virgin on taking Paul Allen's vision to the next stage." It is expected that Virgin Galactic will formally commence the contractual and design phase of the project after the conclusion of the Ansari X Prize flights and start construction of the first spaceship, the 'VSS ENTERPRISE' in 2005.
