And those exponential advances in raw knowledge have been matched by similar progress in materials, engineering and, not least, computer know-how. What’s more, a suborbital flightテ「ツツ覇ssentially an up and down lob shotテ「ツツ琶s far less complicated and moves a lot slower than an orbital mission. “We’re about 70 times less energetic than an orbital flight,” says Virgin Galactic CEO George Whitesides, former NASA chief of staff. “Can we demonstrated 10 to the negative-ninth reliability like a 777 can? No, but we’ve been flying aircraft for 100 years. We believe we’re building the safest spacecraft ever flown.” |
