The flight of the first private astronaut was not as perfect as it first appeared – a number of glitches occurred during the flight, some potentially catastrophic.
The revelations were made by Burt Rutan, designer of SpaceShipOne, which on Monday became the world's first privately funded craft to enter space. Until the team fully understands exactly what went wrong during the flight, he said, they will not go ahead with the pair of flights needed to claim the $10 million Ansari X-Prize.
Luckily, the glitches did not prevent a successful flight. But pilot Mike Melvill said that a partial failure of the system controlling the spacecraft's orientation could have been disastrous if it had occurred just slightly earlier in the flight,.
The problem struck at the end of the rocket engine's firing time of about 70 seconds, just as Melvill reached space. "As I came out of the atmosphere I no longer had any attitude control," Melvill told New Scientist and other reporters. "If that had happened earlier, I would never have made it and you all would be looking sad right now."
Big bang
Although that was the most serious anomaly, it was not the only frightening moment for the 63-year-old test pilot. There was also a loud bang behind him while the rocket engine was firing.
The team believes this was caused by aerodynamic stresses crumpling a composite material fairing around the engine nozzle. However, Dick Rutan, Burt's brother and a famed test pilot himself, said that fairing could have fallen off completely without endangering the craft.
