China’s next lunar mission, set to launch next month, will have a rover named “Yutu”.

In Chinese folklore, Yutu is the white pet rabbit of Chang’e, the moon goddess who has lent her name to the Chinese lunar mission. Legend has it that, after swallowing a magic pill, Chang’e took her pet and flew toward the moon, where she became a goddess, and has lived there with the white jade rabbit ever since.

Chang’e 2 is the name of the entire mission.

SpaceX successfully completed a countdown dress rehearsal and launchpad hot fire engine test in preparation for the next commercial launch of its Falcon 9 rocket on November 25.

SpaceX successfully completed a countdown dress rehearsal and launchpad hot fire engine test yesterday in preparation for the next commercial launch of its Falcon 9 rocket on November 25.

This was the first such fueling at Kennedy of the Falcon 9.

Update: This article gives some details about why the second engine burn of the upper stage rocket did not occur on the previous Falcon 9 launch, and what SpaceX has done to fix the problem. That failure caused speculation that the engine exploded at the attempt.

It is essential that engine functions in space on the November 25 launch in order for SpaceX to deliver its commercial satellite to its proper geosynchronous orbit.

Construction of Russia’s new Vostochny spaceport is essentially back on schedule.

4:35 pm

Construction of Russia’s new Vostochny spaceport is essentially back on schedule.

“I think we have reduced the lag and are getting back to the initial schedule,” Spetsstroy Director Alexander Volosov said on Thursday, November 21. While in July 2013, the lag was about three months, now it has been reduced to ten days. “Funding is provided on time and in sufficient volumes,” Volosov said. The first stage of the project – construction of roads at the cosmodrome – has been completed. The second stage is proceeding as scheduled and is to be completed in December 2014.

On Tuesday NASA issued a solicitation for bids on providing the agency a manned ferrying capability to and from ISS.

The new solicitation asks for proposals for final design, development, test, evaluation and certification of a human space transportation system, including ground operations, launch, orbital operations, return to Earth and landing.

The article is unclear how this solicitation fits in with the commercial crew program that already exists and is funding the manned upgrade of SpaceX’s Dragon and the development of Boeing’s CST-100 and Sierra Nevada’s Dream Chaser.

Update: This article makes things much clearer, outlining how this solicitation is the next phase in development and is open to all bidders.

A close look at another government program to try to lower the cost to orbit.

8:59 am

A close look at another government program to try to lower the cost to orbit.

The latest program is know as the Experimental Spaceplane — or XS-1. The objective “is to demonstrate a reusable first stage launch vehicle capable of carrying and deploying an upper stage that inserts 3,000 to 5,000 lb. payloads into Low Earth Orbit (LEO), designed for less than $5M per launch for an operational system.” The system has to be able to perform with aircraft-like operations. And demonstrate the ability to fly 10 times in 10 days. It needs to reach Mach 10 at least once. And provide the basis for next-generation launch services and “global reach hypersonic and space access aircraft.”

Forgive me if I am skeptical. Despite DARPA’s reasonable success (It helped make possible SpaceX’s Merlin engine), these government efforts generally fail because they are unattached to the prime reasons for lowering cost: competition and profits. Consider this very accurate historical summary in the article above:

In the era of bell bottoms and Richard Nixon, there was the space shuttle. When Ronald Reagan ruled the roost, all hope rested in the National Aerospace Plane. During the Bill Clinton era, there were the X-33 and Venture Star. In Barack Obama’s first term, the Air Force pursued its Reusable Booster System (RBS).

Five programs. One objective: to radically reduce the cost to orbit. More than $14 billion spent on development. And the result? A super expensive shuttle program. Four vehicles that never flew. And access to space just kept getting more expensive.

Only when every effort in the aerospace industry is focused on making itself more competitive will we see the kinds of technical advancements this new DARPA program wishes to achieve.

The new head of the Russian Space Agency has requested that the government impose a ban on the sale of any foreign made satellites in Russia.

The new head of the Russian Space Agency has requested that the government impose a ban on the sale in Russia of any foreign made satellites.

The idea is that Russian industries should build these satellites instead, and that this ban will encourage the rebirth of the Russian satellite business.

I doubt it. If the Russian satellite business could do it better, they would get the business anyway, especially since their labor costs are generally much lower.

China reveals its space station plans.

China reveals its space station plans.

“China Space Station (CSS) will operate in orbit from 2022 to 2032. This period will provide much more opportunities to scientists in China and all of the world after the international space station,” Gu Yidong, president of the China Society of Space Research, said at the American Society for Gravitational and Space Research conference here Nov. 3 – 8. The station’s core module is slated to launch in 2018, followed by two laboratory modules in 2020 and 2022. The outpost will be located in an orbit ranging from 350 kilometers to 450 kilometers above Earth and inclined 42 degrees relative to the planet’s equator.

The article describes in detail their research plans on their station, which sound much the same as the kind of research done on ISS. I suspect this is a bit of misdirection. Their station is clearly designed as a prototype interplanetary station, much like Mir. I believe that any research they do on it will be focused around that fact, which will make that research significantly different that the work done on ISS, which is often not very effective and poorly focused.

A Texas-based company has printed the first 3D-printed metal pistol, a 45 caliber Model 1911.

A Texas-based company has printed the first 3D-printed metal pistol, a 45 caliber Model 1911.

Video below the fold. The gun clearly functions, though I noticed that in the video they never loaded more three rounds in a magazine, and that the gun seems to cycle weakly. I suspect that they had some feeding problems when they tried to fire a full loaded five round magazine.

Nonetheless, this achievement further illustrates that 3D printing is about to become a major method of manufacture.

Successfully growing crops in the desert using salt water and solar power.

Successfully growing crops in the desert using salt water and solar power.

The heart of the SFP concept is a specially designed greenhouse. At one end, salt water is trickled over a gridlike curtain so that the prevailing wind blows the resulting cool, moist air over the plants inside. This cooling effect allowed the Qatar facility to grow three crops per year, even in the scorching summer. At the other end of the greenhouse is a network of pipes with cold seawater running through them. Some of the moisture in the air condenses on the pipes and is collected, providing a source of fresh water.

One of the surprising side effects of such a seawater greenhouse, seen during early experiments, is that cool moist air leaking out of it encourages other plants to grow spontaneously outside. The Qatar plant took advantage of that effect to grow crops around the greenhouse, including barley and salad rocket (arugula), as well as useful desert plants. The pilot plant accentuated this exterior cooling with more “evaporative hedges” that reduced air temperatures by up to 10°C. “It was surprising how little encouragement the external crops needed,” says SFP chief Joakim Hauge.

The technology development here is wonderful, but it is unclear from the article whether these crops would be competitive on the open market with ordinary farm crops. The cost for this operation is not outlined.

India has begun the countdown for the November 5 launch of its first Mars orbiter.

India has begun the countdown for the November 5 launch of its first Mars orbiter.

Just today, spacetoday.com lists fourteen different stories in the Indian press about this mission, all enthusiastic, thus indicating the excitement in that country over space exploration and this mission in particular. Nor is this event unusual. I’ve noted before how space happy India is. They not only want to catch up and pass their neighbor China, they want to catch up with the United States and Russia. Should be fun to watch.

Bras in space: How a bra company made the spacesuits the astronauts wore on the Moon.

Bras in space: How a bra company made the spacesuits the astronauts wore on the Moon.

Fascinating interview, though I find it humorous how it is considered absurd and unlikely for a private company that makes bras to make these spacesuits. In truth, when the Apollo missions happened, Americans had no doubt that ordinary private businesses were the best places to go to get something novel and creative done.

A fundamental design failure appears to be the cause of the fuel leak that caused the launch postponement of India’s first home-made geosynchronous powered rocket in August.

8:57 am

The complete failure of the fuel tank appears to be the cause of the massive leak that caused the launch postponement of India’s first home-made geosynchronous powered rocket in August.

Mr. Radhakrishnan [head of India’s space agency] said while the expert committee had attributed the fuel leak to stress corrosion cracking of the tank filled with propellants, exactly why this happened was “a research problem” that remains to be investigated. The next GSLV mission will switch to a better aluminium alloy material for its propellant tanks.

Up to now the reports have been somewhat vague about the cause of what was clearly an extensive leak. This story tells us that the tank essentially failed. As they filled it with propellants, cracks apparently showed up everywhere, with fuel spewing out in all directions. As far as I can remember, I don’t think there has ever been a rocket tank failure quite this spectacular.

This suggests there were fundamental design flaws in the tank or very serious quality control problems in its manufacture. With the next launch attempt scheduled for December 15, I hope India has identified the source of this incredibly basic problem and taken action to prevent it from happening again.

Update: Reader Patrick Ritchie found this older article which suggests the failed tank was an old tank of a design that was “prone for delayed cracks”. The error here then was in using this substandard old equipment rather than a newer tank.
