Cygnus was successfully berthed to ISS today.

This is the first operational station resupply mission carried out by Orbital Sciences under a $1.9 billion contract with NASA calling for at least eight flights and delivery of 40,000 pounds of cargo and supplies.

The Cygnus captured Sunday will remain attached to the space station until mid February. At that point SpaceX will step up with launch of a Dragon cargo ship around Feb. 22. It will be the third operational resupply flight by SpaceX, which holds a $1.6 billion contract to deliver more than 44,000 pounds of supplies over a dozen missions.

SpaceShipTwo successfully completed its third powered test flight today.

2:03 pm

The competition heats up: SpaceShipTwo successfully completed its third powered test flight today.

On release, SS2’s rocket motor was ignited, powering the spaceship to a planned altitude of 71,000 ft. – SS2’s highest altitude to date – and a maximum speed of Mach 1.4. SS2’s unique feather re-entry system was also tested during today’s flight. Two important SS2 systems, the RCS [reaction control system] and thermal protection coating, were tested during today’s flight in preparation for upcoming full space flights. The spaceship’s RCS will allow its pilots to maneuver the vehicle in space, permitting an optimal viewing experience for those on board and aiding the positioning process for spacecraft re-entry. The new reflective protection coating on SS2’s inner tail boom surfaces is being evaluated to help maintain vehicle skin temperatures while the rocket motor is firing.

Orbital Sciences has successfully launched its Cygnus cargo ferry into orbit.

Orbital Sciences has successfully launched its Cygnus cargo ferry into orbit.

Another perfect launch for the company.

Consider once again what has happened. While it cost NASA six years and $9 billion to build nothing before its Constellation program was cancelled, two private companies have built and launched two different rockets and unmanned cargo spacecraft in that same time period for about a third of that cost.

The contrast couldn’t be more stark. And that contrast will get even more stark as the flights of the privately built manned spacecraft by SpaceX, Boeing, and Sierra Nevada unfold in the coming three years, while SLS and Orion sit around and do little but spend money.

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

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.

8:52 am

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.

The competition heats up: After more than a decade of failed attempts, India has finally successfully launched its Geosynchronous Satellite Launch Vehicle (GSLV).

Moreover, this rocket was entirely built in India. It now gives that country a rocket competitive in the international communications satellite launch market.

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.

8:41 am

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.

3:23 pm

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.
