SpaceShipTwo Tests Its Rocket Engine and Goes Supersonic 103
ehartwell writes "It's official. This morning, after WhiteKnightTwo released SpaceShipTwo at an altitude of around 50,000 feet, pilots Mark Stucky and Mike Alsbury ignited the engine for a roughly 16-second blast. After the engine cutoff, the plane coasted back to its landing back at the Mojave airport. Virgin Galactic tweeted that the pilots confirmed 'SpaceShipTwo exceeded the speed of sound on today's flight!' Its predecessor, SpaceShipOne, first went supersonic December 17, 2003."
Terribly Exciting - 10 years ago (Score:3, Insightful)
When Spaceship One blasted off to win the X-Prize. I remember being very excited. I watched the launch and read as many articles about it as I could.
That was 10 years ago. Now we have SpaceX and Orbital Sciences making orbit. Tremendous new things seem possible now with Falcon Heavy and Grasshopper reusable stage coming in the pipeline. SpaceShipTwo? A bigger version of SpaceShipOne that carries passengers, but still only suborbital with no further prospects. Where is the Tier Two orbital program that Rutan hinted at? Why did it take so long to get SS2 off the ground? Did Scaled get lost and rudderless with Burt retiring? Did they lack funding? What's the deal?

SpaceX will be ferrying people soon enough.
There is a world of difference between hops up to 100 miles and actually going into an orbit.

Why is it taking Virgin Galactic so long for development? Is it a financing or technical issue?
SpaceX was founded in 2002 and is already making re-supply missions to the ISS. Granted that's not quite the same as human spaceflight but it seems like there's a lot faster advancement occurring at SpaceX than at Virgin Galactic.
They are approaching it from a cost-is-everything perspective, instead of an orbit-is-everything perspective. The SpaceX supply missions run at least $20,000 per orbited kilo. For a person to buy a ticket, even if they were treated as cargo, would cost in the $1.5M range. For Virgin Galactic to say that they will get a human up and down (safely) for around 1/10th that price, requires approaching the problem a lot differently (for example, a multi vehicle setup).
