Scaled Composites did an engine test today in Mojave of an alternative engine for SpaceShipTwo.

The competition heats up: Scaled Composites did an engine test today in Mojave of an alternative engine for SpaceShipTwo.

In this case, the company is even competing with itself, in that its first engine design is now in competition with another engine design. Considering the rumors about problems with that first design, I suspect the new design is probably winning.

An outline of Dream Chaser’s test flight schedule for the next three years, leading to its first crewed flight in 2017.

An outline of Dream Chaser’s test flight schedule for the next three years, leading to its first crewed flight in 2017.

The article makes a big deal about Sierra Nevada’s completion of a NASA paperwork milestone, but to me the aggressive flight schedule is more interesting, including news that the engineering vehicle used in the test flight in October was not damaged in landing so badly it could no longer be used.

The Dream Chaser Engineering Test Article (ETA) has since arrived back in her home port in Colorado, following her eventful exploits in California. Despite a red-faced landing for the baby orbiter, she earned her wings during an automated free flight over the famous Edwards Air Force Base, a flight that was perfectly executed, per the objectives of the Commercial Crew check list. The vehicle will now enjoy a period of outfitting and upgrading, preparing her for one or two more flights – listed as ALT-1 and ALT-2 – beginning later this year. Both will once again be conducted at the Dryden Flight Research Center in California.

The ETA will never taste the coldness of space, with her role not unlike that of Shuttle Enterprise, a pathfinder vehicle used to safely refine the final part of the mission for the vehicles that will follow in her footsteps. The Dream Chaser that will launch into orbit will be called the Orbital Test Vehicle (OTV), which is currently undergoing construction at the Michoud Assembly Facility (MAF). Debuting atop of the United Launch Alliance (ULA) Atlas V, the OFT-1 (Orbital Test Flight -1) is scheduled to take place in late 2016. This flight will be automated, testing the entire Dream Chaser system, prior to the crewed OFT-2 mission in early 2017. [emphasis mine]

I think I will up my bet from yesterday. I am now willing to bet that all of the commercial crew spacecraft chosen by NASA to complete construction will fly their privately built manned spacecraft with crew before NASA flies its first unmanned test flight of Orion/SLS.

A cheaper Japanese launch vehicle is scheduled to launch next month.

A cheaper Japanese launch vehicle is scheduled to launch next month.

The story is actually not very informative. What is interesting is the spin of the article: Japan’s rockets are getting cheaper! This suggests to me that the pressure brought to bear by SpaceX’s lower prices is being felt quite strongly.

We really don’t know if this Japanese rocket is cheaper to launch. What we do know is that, for the first time in decades, Japan feels compelled to use that sales pitch to sell its rockets. Isn’t competition great?

NASA’s first test flight of both the Orion capsule and the heavy-lift SLS rocket in 2017 might be delayed because of design problems with the European-built service module.

9:29 am

I am shocked, shocked! NASA’s first test flight of both the Orion capsule and the heavy-lift SLS rocket in 2017 might be delayed because of design problems with the European-built service module.

Overweight and struggling with design delays, the European-built service module for the Orion crew exploration vehicle may not be ready for a much-anticipated test flight by the end of 2017. The preliminary design review for the Orion spacecraft’s critical engine and power element is now on track for May after a six-month delay to contend with weight issues, according to Thomas Reiter, director of the European Space Agency’s human spaceflight and operations programs.

I am willing to bet that SpaceX will put astronauts in space on Dragonrider before this unmanned SLS flight occurs.

SpaceX has signed a contract with a Japanese commercial satellite company.

8:34 am

The competition heats up: SpaceX has signed a contract with a Japanese commercial satellite company.

The story was first reported on Friday, but I was busy this weekend and forgot to post it. Key quote:

The launch contract award for JCSAT 14, a communications satellite owned by Tokyo-based SKY Perfect JSAT Corp., adds another mission to SpaceX’s backlog, which stands at nearly 50 missions worth nearly $5 billion, according to a company press kit.

As SpaceX rolls these missions out and the money rolls in, it will insure the likelihood that they will build the Falcon Heavy as promised. And when they do, they will have created a heavy lift rocket and done it for pennies, compared to the costs spent on numerous government projects attempting to do the same.

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.

11:18 pm

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.

3:35 pm

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.

8:42 am

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.
