NASA and the Obama administration have announced their support for extending ISS’s operations for more years to at least 2024.

Obviously, Congress needs to agree with funds. Moreover, so do the Europeans, Russians, and Japanese, though they all have been pushing to extend ISS for awhile.

Now maybe NASA will finally consider doing some of those year-long plus manned missions on ISS that are essential if humans are eventually going to go to Mars and beyond.

The European Space Agency announced today that it is studying using Sierra Nevada’s Dream Chaser spacecraft for manned flights.

The European Space Agency announced today that it is studying using Sierra Nevada’s Dream Chaser spacecraft for manned flights.

This arrangement allows ESA to prove its hardware and technology in space on a crewed spacecraft. In exchange, SNC will have its development costs and production time potentially lessened as well as benefit from the extensive experience of ESA and its industrial partners. At the end of an initial evaluation and planning phase, which will continue through 2014, the organisations expect to continue the relationship through a long-term agreement leading to flight operations. Both entities foresee further arrangements to continue the partnership towards the potential use of Dream Chaser for European missions.

This supplements an earlier announcement by Germany which also is considering using Dream Chaser.

Orbital Sciences has scrubbed today’s launch of Cygnus due to the major solar flare that occurred yesterday.

“Early this morning the Antares launch team decided to scrub today’s launch attempt due to an unusually high level of space radiation that exceeded by a considerable margin the constraints imposed on the mission to ensure the rocket’s electronic systems are not impacted by a harsh radiation environment,” Orbital Sciences officials said in a statement today.

Arianespace, in an effort to trim costs, is considering slashing the number of companies that will build its next generation rockets from 150 to 50.

The competition heats up: Arianespace, in an effort to trim costs, is considering slashing the number of companies that will build its next generation rockets from 150 to 50.

You might call this the SpaceX effect. Their success and lower launch costs is forcing changes throughout the launch industry.

Note also that there is certainly a lot of room for Arianespace to trim, considering that this European rocket company has still never made a profit, despite dominating the commercial launch market for years.

Boeing is moving its X-37B operations to the Kennedy Space Center.

A spy plane used by the U.S. Air Force is about to get a new home: a garage at Kennedy Space Center that once housed NASA orbiters during the space shuttle era. The move was announced Friday by Boeing, the Chicago-based company that built the X-37B spy plane and is in charge of repairing the spacecraft whenever it returns to Earth. Previously, Boeing had refurbished the 29-foot-long spacecraft at Vandenberg Air Force Base in California, but the company decided to relocate its fix-up shop in Florida, where the vehicle now launches.

The second commercial launch on SpaceX’s Falcon 9 rocket has been delayed three days until January 6 because an unspecified issue with the rocket’s fairing.

It appears the company wants to do some additional inspections of the rocket, just to be sure all is well. They haven’t been more specific then this,

The geological history of Venus: What’s known, not known, and unknown.

11:48 am

The geological history of Venus: What’s known, not known, and unknown.

This is a very clearly written overview by James Head, one of the world’s preeminent planetary geologists, of what has been learned about the geology of Earth’s sister planet, the planet of a million volcanoes. Key quote:

Many features on Venus (folded mountain belts, rift zones, tesserae) were like Earth, but there were few signs of Earth-like plate tectonics, so that Venus seemed to have a single lithospheric plate that was losing heat conductively and advectively. But the cratering record presented a conundrum. First, the average age of the surface was <20% of the total age of the planet, and second, the average was not a combination of very old and very young surfaces, such as Earth’s continents and ocean basins. Third, the lack of variability in crater density, and of a spectrum of crater degradation, meant that all geological units might be about the same age. This implied that the observed surface of Venus must have been produced in the past hundreds of millions of years, possibly catastrophically, with very little volcanic or tectonic resurfacing since then! Suddenly, Venus was not like Earth, nor like the Moon, Mars, or Mercury.

Some scientists even believe that Venus was essentially resurfaced in a massive volcanic event about a half billion years ago. Others disagree. Meanwhile, the European probe Venus Express has gotten hints that volcanic activity is still going on.

As Head concludes, it has been 20 years since the last spacecraft arrived at Venus to do geological research. It is time to return.

Mars One narrows its applicant pool of would-be Martian colonists from 200,000 to just over a 1000.

6:08 pm

Mars One narrows its applicant pool of would-be Martian colonists from 200,000 to just over a 1000.

People started applying for a voyage to the red planet in April 2013 through Mars One, a Netherlands-based private venture that wants to land humans there by 2025. By the time the company stopped taking applications, more than 200,000 people had submitted one. Today, Mars One announced that it’s made a short(er) list of 1,058 applicants.

These are individuals willing to make a one way trip.

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 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 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.

9:21 am

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.

9:15 am

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.
