A Progress freighter, launched yesterday, will not dock with ISS for four days in order to test upgrades to its rendezvou radar system.

Unlike recent Progress vehicles that used the 2AO-VKA and AKR-VKA antennas of Kurs-A system, M-21M is sporting a AO-753A antenna of the Kurs-NA system instead. Once the Progress reaches its preliminary orbit, it will conduct a series of automated engine burns to put it on track to fly within one mile of the station on Wednesday, allowing for the test of the lighter, more-efficient Kurs automated rendezvous system hardware for upgraded Soyuz and Progress vehicles.

After it finishes its flyby, the Progress will loop above and behind the station, returning Friday for a docking.

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.

In an interview Richard Branson says that Virgin Galactic is working to replace SpaceShipTwo’s hybrid engine.

In an interview Richard Branson says that Virgin Galactic is working to replace SpaceShipTwo’s hybrid engine.

So for instance, the initial rocket which I’ll be flying on to space will be thrown away afterward. Within six to nine months, we will be using rockets that will have capability of being used maybe up to 1,000 times, but definitely up to 100 times. That will bring the cost of space travel down dramatically.

This timing fits with their new schedule for the first commercial flights of SpaceShipTwo sometime late in 2014. I suspect they are hoping to fly the ship a few more times with the troublesome hybrid engine, partly for engineering research and partly to keep interest up in the company, and then switch over to a new engine.

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.

To save money, NASA management has shut down a troubled program to build a more efficient plutonium power supply for its deep space missions.

To save money, NASA management has shut down a troubled program to build a more efficient plutonium power supply for its deep space missions.

The cancelled ASRGs would have generated electrical power from the expansion of gas warmed by the radioactive decay of plutonium-238. NASA says that the devices have the same power output as its current generation of Multi-Mission Radioactive Thermoelectric Generators (MMRTG) but use four times less plutonium-238, a scarce resource. One MMRTG with 4.8 kilograms of plutonium is currently powering the Curiosity rover on Mars.

The United States has less than 40 kilograms of plutonium-238 left, but the DOE restarted production this year. Green says he is confident that the DOE will be producing plutonium-238 at a rate of 1.5 kilograms per year by 2019. He says that the stockpiled plutonium-238, along with the new supply, will be enough to send another planned rover to Mars in 2020 and to complete other missions in the 2020s – without any need for the extra efficiency of the ASRGs.

The ASRG program had been a year and a half behind schedule and had had its management team replaced at one point.

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

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 detailed update on the status of spacesuit repairs on ISS, following the July water leak during a spacewalk.

After additional tools and parts were sent up on both Progress and Cygnus freighters, astronauts on ISS pinpointed the problem and replaced the failed the “fan/pump/separator”. The faulty unit was brought back to Earth for further analysis in the manned Soyuz craft yesterday.

Of the four U.S. spacesuits on ISS, one is still considered faulty and needs to be replaced, which will happen with the next Dragon flight expected sometime in February 2014.
