The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

The damage, caused by the undeployed Progress antenna, appears to have involved a navigational aid needed for ATV-4 … the Laser Radar Reflector (LRR) target. The LRR is needed for the automatic docking of the European ATV during the last part of the rendezvous operations. If the damage is confirmed, the device, recently replaced during an EVA by the Russian crew due to contamination of the optical section, will need to be replaced again. In this event, the European cargo ship could potentially be delayed for several months. ATV-4, named Albert Einstein, has been already delayed from April to June because of a glitch in an avionics box.

NASA has now agreed to contribute equipment and researchers to a European dark energy mission.

The check is in the mail: NASA has now agreed to contribute equipment and researchers to a European dark energy mission.

And why should Europe have any expectation that NASA will follow through? Europe’s ExoMars project was screwed badly when NASA pulled out last year. Nor was that the first time the U.S. government reneged on a deal with Europe.

Considering the fragile nature of the U.S. federal budget, I wouldn’t depend on anything from NASA or any U.S. government agency for the foreseeable future. And this includes the various private space companies such as SpaceX and Orbital Sciences that are using NASA subsidies to build their spaceships. Get those things built, and quickly! The government money could disappear very soon.

In meetings today the European Space Agency has decided to upgrade Ariane 5 rather than immediately build a new Ariane 6 rocket.

In meetings today the European Space Agency (ESA) has decided to upgrade Ariane 5 rather than immediately build a new Ariane 6 rocket.

Normally I would label this story as an example of “the competition heating up.” In this case, however, I don’t see how an upgrade of Ariane 5 can possibly be competitive. The rocket has been so expensive to operate that — even though it has dominated the launch market for years and is very reliable — ESA has had to subsidize its cost. It has never made a profit. I don’t see how they can reconfigure it enough to bring its cost down to compete with Falcon 9. In other words, they are trying to put lipstick on a pig.

Nor is this surprising. Arianespace is a government-run business, operated like a committee with the member nations of ESA all having a say. Under this arrangement, it is difficult if not impossible to get a quick and efficient decision. Moreover, political concerns will often outweigh issues of efficiency and profits.

In the open competitive market of privately-run companies that the launch market is becoming, I am very skeptical this kind of business can survive.

Faced with stiff competition in the launch market, Europe struggles to come up with a competitive replacement for Ariane 5

Faced with stiff competition in the launch market, Europe struggles to come up with a competitive replacement for Ariane 5

“I strongly believe we have to decide, as quickly as possible, to develop a new-generation launcher to be competitive in the market as it is forecast, and with the competitors,” [ESA Director General Jean-Jacques] Dordain said at the Berlin air show last month, a reference to new launch vehicle developments in India, China and the U.S., where Space Exploration Technologies’ low-cost Falcon 9 is challenging the global launcher market.

While space cadets might argue about launch prices till the cows come home, the actual competitors in the industry know better: SpaceX’s low prices are real and are forcing everyone to find ways to lower costs or lose business.

A computer glitch prevented the undocking of the European ATV-3 cargo vehicle from ISS today.

A computer glitch prevented the undocking of the European ATV-3 cargo vehicle from ISS today.

Undocking of the European Space Agency’s third Automated Transfer Vehicle, or ATV, from the aft port of the Zvezda module had been scheduled for 6:35 p.m. EDT (GMT-4). Cosmonaut Yuri Malenchenko attempted to send a command to begin the undocking sequence on time, but the command apparently never reached the docking mechanism.

I am not sure what will happen if they cannot pin down the problem. For example, it is unclear whether the cargo vehicle can be reprogrammed to be manually controlled. Also, it presently blocks a docking port. Is that port needed for the next ATV freighter as well as for other craft, such as Progress freighters? If so, this could become a serious problem.

France and Germany in the European Space Agency are at loggerheads about the best way to compete in the launch market.

9:51 am

The competition heats up: France and Germany in the European Space Agency are in serious disagreement about whether to replace the Ariane 5 or upgrade it.

The French space agency, CNES, quietly backed by Europe’s Arianespace launch consortium, has argued that the current Ariane 5 heavy-lift vehicle has only a fragile hold on its current 50 percent commercial market share. Just as important, according to the French reasoning, is that the entire Ariane 5 system, including its ground infrastructure, is expensive to operate and likely to remain so. Because money is short in Europe, it would be preferable to move immediately to a next-generation vehicle that would carry payloads ranging from 2,500 kilograms to 6,000 kilograms — with an extension to 8,000 kilograms — into geostationary transfer orbit, one at a time. This modular vehicle ultimately would replace not only today’s Ariane 5, but also the Russian Soyuz rocket that is now operating from Europe’s Guiana Space Center in French Guiana.

Set against this reasoning are industrial policy issues raised by the German space agency, DLR, and by Astrium, which is Ariane 5’s prime contractor. They say Europe needs to complete development of an upgraded Ariane 5 — at a cost of about 1.4 billion euros ($1.8 billion) — before embarking on a decade-long development of an Ariane 6 whose cost and industrial work-share distribution are unknown. [emphasis mine]

It is very clear that ESA has recognized that once Falcon 9 becomes completely operational, it will be difficult to get anyone to buy tickets on the very expensive Ariane 5. From the article it appears the battle centers on the fact that the French realize this, while the Germans are willing to look the other way.
