Richard Branson Says He's Going to Send People Into Space by Christmas (cnn.com)

Would you pay $200,000 for a ride into space? I ask beause billionaire Richard Branson "really, really wants you to believe he's going to send people to space -- and soon," reports Gizmodo. "In a new interview with CNN, the Virgin Group founder now says he's "reasonably confident" his spaceflight company can beat out competitors like Blue Origin and SpaceX with crewed trips to space before Christmas."

An anonymous reader quotes CNN: "We have a brilliant group of astronauts who literally believe 100% in the project, and give it their everything," he said. The first few trips to space will be flown by test pilots without anyone else on board. Branson says he will be the first passenger. Eventually, paying tourists will also make the trip....

The design and flight control systems of SpaceShipTwo were overhauled following a 2014 test flight crash that killed a co-pilot. Branson has said the accident made him question whether to continue pursuing his riskiest business venture. But the company said it received an outpouring of support, including from customers who had reserved $200,000 to $250,000 tickets to one day ride in SpaceShipTwo. Hundreds of people are still lined up for a shot. The flight will offer tourists a few minutes of weightlessness and views of Earth's curved horizon....

Branson is known to set deadlines that aren't met. Virgin Galactic has been developing SpaceShipTwo since 2004, and Branson initially said commercial rides would begin in 2007. Eleven years later, the firm is still working on getting its 600 customers into space. "Space is difficult. Rocket science is rocket science," Branson said. "I obviously would love to prove our critics wrong, and I'm reasonably confident that before Christmas, we will do so."

"We'll see," writes Gizmodo.

    The distinction is "going to space" vs. "going to orbit". His listed "competitors" - Blue Origin and SpaceX - aren't targeting "space", they're targeting orbit. It's an entirely different thing, and involves your craft gaining more than an order of magnitude more energy than simply crossing the Karman line. 100000m * 9,81 m/s = 0,981 MJ/kg. 1/2 * (7800m/s)^2 + 350000 * 9,81 = 33,8535 MJ/kg - that is to say, over 34 times more energy**.

    Reaching orbit is a little bit of "up" and a LOT of "across". Or, as XKCD put it: how the public thinks going to orbit works vs. how it actually works.

    ** In practice, the consumed energy distinction isn't as stark, as both vehicles have to deal with air resistance and gravity losses for the first part of the flight - but on the other hand, it's a far-more-than-linear increase in difficulty to add more delta-V, since you have to lift the fuel to lift your fuel, and lift the fuel to lift that fuel, and lift the fuel to lift that fuel...
