Boom Supersonic’s recent rollout of its XB-1 supersonic demonstrator aircraft marked a milestone in an accelerating race to revive an era of civilian supersonic travel that ended when the Concorde jetliner was retired in 2003.

XB-1, aka Baby Boom, is set to begin flight tests next year from the Mojave Air and Space Port in California. The Mach 2.2 (2,717 km/h, 1,688 mph) vehicle is the precursor to Boom’s 55-seat Overture airliner, which is scheduled to begin carrying passengers in 2029.

A Look at SpaceX’s and Virgin Galactic’s Hypersonic Plans

I found this video entertaining. I’m not sure this guy has any grasp of the technological challenges or how SpaceX and Virgin Galactic are trying to tackle it.

He also calls a pair of routine pilot proficiency flights of WhiteKnightTwo at Spaceport America mysterious. Nothing really unusual about them. They conducted these flights at Mojave regularly.

Hypersonic sounds great, but it’s not clear when or if it will carry passengers. What we might be left with are hypersonic weapons indistinguishable from nuclear missiles. The chance of an accidental nuclear exchange could become much greater.

Richard Branson’s Virgin Galactic Goes Public With Extravagant Promises to Keep

After 15 years of making extravagant but unkept promises to fly more than 600 “future astronauts” to space, Richard Branson must now please an entirely new group of people who are usually much shorter on patience: shareholders.

Following the completion last week of a merger with Social Capital Hedosophia (SCH), the British billionaire’s Virgin Galactic suborbital “space line” will begin trading under its own name on the New York Stock Exchange (NYSE) on Monday.

Going public now is an unusual move for a space tourism company that hasn’t flown a singlet tourist to space since Branson announced the SpaceShipTwo program in 2004. Some might see it has putting the cart before the horse.

Reaction Engines has received a large investment by Boeing HorizonX and two other companies, CNBC reports.

The U.S. industrial giant joined Rolls-Royce and defense company BAE Systems in a $37.6 million fundraising round for U.K.-based propulsion company Reaction Engines. This is both the second foreign investment and the second space investment for Boeing HorizonX Ventures, which contributed to the $15 million funding round for Australian satellite company Myriota last month.

Reaction Engines’ advanced propulsion “could change the future of air and space travel,” according to Boeing HorizonX vice president Steve Nordlund.

“We expect to leverage their revolutionary technology to support Boeing’s pursuit of hypersonic flight,” Nordlund said in a statement.

Reaction Engines, which has now raised more than $140 million over the last three years, is developing a hybrid jet and rocket engine. In theory, the company’s SABRE engine will be capable of operating as a jet at take-off and transitioning to a rocket at higher altitudes.
