Fifty years ago: Alan Shepard’s suborbital flight

8:01 pm

An evening pause: Fifty years ago today, America’s response to Gagarin and the Soviets, Alan Shepard’s suborbital flight.

Or as he said as he lifted off, “The clock has started.”

The flight actually lasted 15 minutes 22 seconds. Though only a fourth the size of Gagarin’s much bigger Vostok capsule, the Mercury capsule was steerable. During the flight Shepard adjusted the capsule’s pitch, roll, and yaw, proving that humans could pilot a spacecraft manually.

Space Adventures and tourists to the Moon

7:06 pm

Space Adventures and tourists to the Moon.

After consultation with Rocket Space Corporation Energia, modifications to the Soyuz TMA configuration have been agreed upon. The most important of which is the addition of a second habitation module to the Soyuz TMA lunar complex. The additional module would launch with the Block DM propulsion module and rendezvous with the Soyuz spacecraft in low-Earth orbit.

“Space Adventures will once again grace the pages of aerospace history, when the first private circumlunar mission launches. We have sold one of the two seats for this flight and anticipate that the launch will occur in 2015,” said Richard Garriott, Vice-Chairman of Space Adventures. “Having flown on the Soyuz, I can attest to how comfortable the spacecraft is, but the addition of the second habitation module will only make the flight that more enjoyable.”

FAA wants your opinion about commercial space rules

9:51 am

The government marches on! The FAA wants your opinion about its future commercial space regulations.

Or to put it another way, how to stifle a newborn in the womb. In 2004 I said the new law allowing this kind of regulation was going to hurt the new space industries. We are about to see, with the FAA’s regulatory effort here, exactly how that will play out.

And I don’t think it will be good.

SpaceShipTwo’s First “Feathered” Flight

2:15 pm

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

9:39 am

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

9:35 am

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

8:01 pm

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

11:59 pm

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.
