Virgin Galactic’s SpaceShipTwo hits Mach 1.9 in second successful test flight

Virgin Galactic is celebrating a successful second test flight of SpaceShipTwo, the rocket-powered passenger spacecraft that may someday take tourists to the edge of space. Today’s test took the VSS Unity, the second craft built in this class, up to 114,500 feet and Mach 1.9, or nearly 1,300 miles per hour.

Unity’s first powered flight was less than two months ago, which was itself the first powered flight Virgin Galactic had attempted since the fatal breakup of the company’s previous SpaceShipTwo-class spacecraft, Enterprise, in 2014.

Much has been redone since then but the basics of the Virgin Galactic flight style are the same. A relatively traditional jet-powered plane, a WhiteKnightTwo class plane (in this case the VMS Eve), carries the SpaceShipTwo craft (Unity) up to somewhere around 45,000 feet. There the latter detaches and fires up its rocket engine, accelerating to high speed and high altitude, after which it glides to the surface and lands more or less like any other plane.

Jeff Bezos and his Blue Origin space venture go all in on moon settlements

LOS ANGELES — Amazon billionaire Jeff Bezos says his Blue Origin space venture will work with NASA as well as the European Space Agency to create a settlement on the moon.

And even if Blue Origin can’t strike public-private partnerships, Bezos will do what needs to be done to make it so, he said here at the International Space Development Conference on Friday night.

Bezos laid out his vision for lunar settlement during a fireside chat with yours truly, which took place just after he received the National Space Society’s Gerard K. O’Neill Memorial Award.

NASA is bringing cryosleep chambers out of fiction and into science

You probably thought it was infinitely cool when Ripley and the crew of the Nostromo first emerged from their cryosleep chambers in Alien, but now that slice of sci-fi could become a reality in our lifetime.

NASA and SpaceWorks Enterprises are currently developing a stasis chamber (as opposed to individual pods like those in the movie) that could induce an extended state of torpor, or metabolic inactivity medically brought on by lowering body temperature to the point of mild hypothermia, that could allow astronauts to snooze for at least two weeks on end during longer missions. Also unlike Alien, in which everyone is temporarily in freeze-frame until the ship arrives at its destination, the crew would rotate cryosleep shifts so there is always someone conscious in case something goes awry where no one can here you scream.

SpaceWorks’ objective is to “place crew and passengers in a prolonged hypothermic state during space-mission transit phases (outbound and Earth-return) to significantly reduce the system mass, power, habitable volume, and medical challenges associated with long-duration space exploration,” as explained on their website.
