The company for the high resolution cameras that the Russian astronauts were unable to install on ISS during their spacewalk last week has issued an update.

The installation of the cameras proceeded according to plan and without incident. During a spacewalk, Russian cosmonauts were able to transport the cameras to their mounting position and install them quickly and efficiently. However, soon after installation, the Mission Control Centre (MCC) outside of Moscow was unable to receive any data from either camera (contrary to what was reported during the live transmission of the spacewalk). Without this data, engineers in the MCC were not able to confirm that the cameras were receiving the power necessary to allow them to survive the temperature fluctuations of the space environment. As a consequence, senior technical personnel from UrtheCast and RSC Energia (UrtheCast’s Russian partner) jointly decided that the safest and most prudent course of action was to uninstall the cameras and bring them back inside the ISS to be reinstalled at a later date, once the data transmission problem has been solved.

UrtheCast’s Chief Technology Officer, Dr. George Tyc, was present at the MCC throughout the operation, along with the Company’s Chief Engineer for Space Systems, Mr. Greg Giffin. Said Dr. Tyc, “The fact the neither camera could communicate with the MCC strongly suggests that the problem lies inside the ISS and it is not a problem with the cameras or external cables. This kind of issue has been encountered before on the ISS and can be fixed in the near-term. Bringing the cameras back inside to be installed another day was simply the right engineering decision.”

No word on what caused the problem, but as this commercial project is being done in partnership with the Russians and the Russians are whom the company is working to solve the technical problem it was almost certainly on the Russian portion of ISS.

SpaceX successfully completed a static fire engine test Saturday in preparation for its next commercial satellite launch on January 3.

The competition heats up: SpaceX successfully completed a static fire engine test Saturday in preparation for its next commercial satellite launch on January 3.

It will be a busy next two months for commercial space. Cygnus is scheduled to launch on January 7, while Dragon makes its next flight on February 22. During that same time period a Russian Progress freighter will be launched. Also, there will be two Ariane 5 launches and one Proton launch, plus one commercial launch by India along with that country’s first launch of its home-built GSLV rocket.

As I say, the competition is heating up.

The competition heats up: India has now set January 5 as the date for the test launch of its homebuilt powerful GSLV rocket.

India’s needs this more powerful rocket if they are going to be a serious player in the new colonial movement in space. They have had many problems over the past decade trying to get it operational. Maybe now they will finally succeed.

Today’s spacewalk by two Russian astronauts on ISS set a new Russian duration record though one of the two commercial cameras was unable to transmit its data to the ground.

Today’s spacewalk by two Russian astronauts on ISS set a new Russian duration record though one of the two commercial cameras installed was unable to transmit its data to the ground.

For reasons that are unclear, the astronauts were then instructed to disconnect both cameras and bring them back inside ISS. This caused the cancellation of a number of other tasks and was the reason the spacewalk was the longest ever by Russian astronauts.

Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.

Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.

Late this month, ESA’s Mars Express will make the closest flyby yet of the Red Planet’s largest moon Phobos, skimming past at only 45 km [28 miles] above its surface. The flyby on 29 December will be so close and fast that Mars Express will not be able to take any images, but instead it will yield the most accurate details yet of the moon’s gravitational field and, in turn, provide new details of its internal structure.

China’s rover about to go to sleep for the long lunar night.

China’s rover is about to go to sleep for the long lunar night.

According to Wu Fenglei of the Beijing Aerospace Control Center, the lander will “go to sleep” at about 7 a.m. on Christmas Day and the moon rover, Jade Rabbit, will fall asleep at about 1 a.m. on Boxing Day. The forthcoming lunar night, expected to begin on Dec. 26, will last for about two weeks, experts with the center estimated. During their “sleep”, both lander and rover will have to tolerate minus 180 degrees Celsius. Scientists tested the lander early Tuesday to ensure it can stand the temperature drop. Both lander and rover are stable, said Wu, adding they have completed a series of scientific tasks in the past two days.

This report states the rover landed in Sinus Iridum, the original announced landing site, contradicting other reports that said the lander came down in Mare Imbrium.

This news report, confirmed by no other source, claims that the spacewalk this week was cut short because of water in the astronauts’ spacesuits.

This news report, confirmed by no other source, claims that the spacewalk this week was cut short because of water in the astronauts’ spacesuits.

I report this story but am very puzzled. If a water leak was the cause of the shortened spacewalks, I would have expected others to report that fact as well. No one has, however. (See this nasaspaceflight.com article, for example, which outlines the entire engineering situation quite thoroughly but says “both suits performed well during the EVA.”) Moreover, the ABC particular story above is written by someone who is not a space reporter, and contains some incongruities that reflect that, making me even more skeptical.

Yesterday’s spacewalk on ISS, though successful, was cut short because of spacesuit discomfort issues unrelated to the earlier water leak problems.

Yesterday’s spacewalk on ISS, though successful, was cut short because of spacesuit discomfort issues unrelated to the earlier water leak problems.

No story on the spacewalk is entirely clear on the issues. Astronaut Rick Mastracchio was cold, but it seems he also had other problems that have not been outlined clearly. Interestingly he was not using the spacesuit that flooded in July. Michael Hopkins was using that suit and apparently had no problems.

In order to resize the spare suit on the station for Mastracchio they have delayed the next spacesuit for one day.

It seems Curiosity’s wheels are wearing out faster than expected and engineers want to know why.

It seems Curiosity’s wheels are wearing out faster than expected and engineers want to know why.

The increasedwear recently appears to be because the rover was traveling over rougher terrain. Nonetheless, JPL engineers are going to monitor the rover’s travel and wheel damage more closely in order to gauge that wear better for future travel.

SpaceX has set December 31 as the launch date for its next Falcon 9 commercial launch.

The competition heats up: SpaceX has set December 31 as the launch date for its next Falcon 9 commercial launch.

They are picking up the pace. This will be SpaceX’s second commercial launch in December and its second geosynchronous launch. If they prove they can keep this pace through 2014 they will not only clear away a large amount of the launch backlog, they will establish themselves as a solid player in the launch market, a company that the competition must fear due to its low prices.

NASA engineers have decided to go ahead with a series of spacewalks to repair the ISS cooling system, thereby delaying the Cygnus cargo mission until January.

The EVAs will take place on December 21, 23 and 25 followed by a Russian Spacewalk on the 27th and a Beta-Angle Cut-out beginning on December 29. That means that the earliest launch opportunity for Cygnus is January 9, 2014 (local time) – pending the successful execution of the contingency EVAs.

Update: The Orbital Sciences press announcement says their launch can happen no earlier than January 13.

Arianespace has ordered the construction of an additional 18 Ariane 5 rockets.

This construction order, if it reflects actual launch contracts, gives Arianespace some margin while it works to find ways to compete in the launch business, as expressed by the last sentence of the above article: “Astrium managers recently called for a thorough overhaul of the Ariane contractor mix with a view to reducing prices to stay viable in the competitive world commercial launch market.”

Germany has funded a study to look into using Sierra Nevada’s Dream Chaser for its space operations.

The competition heats up: Germany has funded a study to look into using Sierra Nevada’s Dream Chaser for its space operations.

Named DC4EU (Dream Chaser for European Utilization), the project is to explore ways in which the Dream Chasercan be used to cover German and European requirements for the transportation of payloads and astronauts to the International Space Station (ISS) and for deployment as a manned or unmanned space vehicle allowing German and European scientists to conduct research under weightless conditions over extended periods of time. Given the capability which the Dream Chaser has for reaching orbits at a substantially greater altitude than the ISS, the study will determine the extent to which it is able to supply satellites or remove decommissioned satellites from their orbits.

All hail competition and private enterprise! Sierra Nevada designed it. Sierra Nevada built it. Sierra Nevada owns it. If NASA decides it doesn’t want to buy it, there is no reason the company can’t sell it to someone else, for profit.
