Yeah, "rocket" + "safe enough to carry tourists regularly" just seems like a difficult combination.

- untog 12y agoMany years ago, trying to combine "flying in the air" with "safe enough to carry tourists regularly" would be seen in a similar light.
- Animats 12y agoIt took 54 years to go from the Wright Brothers first flight to the Boeing 707. It took 53 years to go from Yuri Gagarin's first flight (one orbit) to this suborbital flight test.
- DanBC 12y agoIt only took 8 / 9 years between Gagarin's flight and landing men on the Moon. That's remarkable. It's depressing to think how much closer we'd be to humans on Mars if we had focussed all the Afghan and Iraq war money on space research.
- jacquesm 12y agoOr simply to reduce the national debt.
- a3n 12y agoIt only took 8 / 9 years between Gagarin's flight and landing test pilots on the Moon. Which is still remarkable. Since this sub-thread has invoked tourists and the implied safety and convenience of a commercial operation that carries passengers and other payload. Tourists are payload, test pilots are ... test pilots.
- smackfu 12y agoFair point, but the failure modes of flying seem to be more addressable than those of rockets. Like if the airplane engine is essential, add enough that you can tolerate a failure. If control surfaces are essential, add redundant systems. Whereas the failure mode of rockets tends to be exploding, and that's pretty hard to mitigate.
- zepolud 12y agoThe failure modes of rocket engines could be explosions but nobody says you can't have multiple redundant engines on a single rocket. In fact, in 2012 Falcon 9 demonstrated exactly that: one of their 9 Merlin engines blew up but the rest redistributed the load and the rocket successfully delivered the payload to the ISS[1].

- robryk 12y agoAccording to the article you are quoting the engine didn't explode; it's just failed. I'd be very impressed if a rocket survived an explosion of one of its engines (they are much closer together than jet engines on a passenger plane and even i such planes an explosion of one engines can damage others due to shrapnel).
