SpaceShipTwo’s First “Feathered” Flight

SpaceShipTwo’s has successfully completed its first “feathered” flight.

After a 45 minute climb to the desired altitude of 51,500 feet, SpaceShip2 (SS2) was released cleanly from VMS Eve [WhiteKnightTwo] and established a stable glide profile before deploying, for the first time, its re-entry or “feathered” configuration by rotating the tail section of the vehicle upwards to a 65 degree angle to the fuselage. It remained in this configuration with the vehicle’s body at a level pitch for approximately 1 minute and 15 seconds whilst descending, almost vertically, at around 15,500 feet per minute, slowed by the powerful shuttlecock-like drag created by the raised tail section. At around 33,500 feet the pilots reconfigured the spaceship to its normal glide mode and executed a smooth runway touch down, approximately 11 minutes and 5 seconds after its release from VMS Eve.

The story behind China’s planned space station begins to emerge

The story behind China’s planned space station begins to emerge.

China first said it would build a space station in 1992. But the need for a manned outpost “has been continually contested by Chinese space professionals who, like their counterparts in the United States, question the scientific utility and expense of human space flight”, says Gregory Kulacki, China project manager at the Union of Concerned Scientists, headquartered in Cambridge, Massachusetts. “That battle is effectively over now, however, and the funds for the space station seem to have been allocated, which is why more concrete details are finally beginning to emerge.”

Though I am always skeptical of comments from the Union of Concerned Scientists, in this case Kulacki makes sense. He also illustrates a further example of what I wrote in 2005, “After more than 40 years of debate, the argument is over and the supporters of manned spaceflight have won.”

“Space beer,” one giant leap for mankind

The science of space beer.

“For example, many metals burn more easily in reduced gravity, liquids behave differently, both of which have important implications for safety and the way machinery and equipment operate in spacecraft and space stations. The beer experiments assisted in determining the correct level of carbonation, so that it can in the future be appropriately enjoyed by humans in reduced gravity,”

Flute duet on Earth and in Space

An evening pause: Though this took place last week, on the fiftieth anniversary of Yuri Gagarin’s flight, I can’t let it go by, especially because it is so nicely done. Trust me, for two flute players to play a duet with one several hundred miles up in space and traveling more than 17,500 miles per hour while the other is safely on Earth is not easy.

NASA Awards Next Set Of Commercial Crew Development Agreements

NASA has awarded the next set of commercial crew development agreements, giving contracts worth from $22 to $92 million to four companies, Blue Origin, Sierra Nevada, SpaceX, and Boeing. More here and here.

The amounts that NASA is giving these companies is minuscule, compared the monies spent on the program-formerly-called-Constellation. Yet I bet they all get their rockets/capsules launched and in operation, supplying cargos and crews to low Earth orbit, before NASA even test fires its heavy-lift rocket.

The 50th anniversary of Gagarin’s spaceflight

I am on the road today, so posting will be light. Though I have many things to say about today’s historic anniversary, fifty years after the first manned spaceflight by Yuri Gagarin, I simply won’t be able to post them. However, I plan to express some of my thoughts on the John Batchelor Show at 11:30 pm (Eastern time) tomorrow. Listen in live, or on his podcast posted shortly after the live show.

The ironies, however, are amazing, and quite depressing. On the same day we celebrate the start of manned space exploration, NASA administrator Charles Bolden will announce where the United States’s three retired shuttles will be put on display. Note also that he does this on the thirtieth anniversary of the first shuttle flight. It is almost as if the Obama administration’s desire to kill the American government space program is so strong that they have to rub salt in the wound as they do it.

I say this not so much because I am in favor of a big government space program (which I am not) but because the timing of this announcement once again illustrates how astonishingly tone-deaf the Obama administration continues to be about political matters.
