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

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.

After postponing Juno’s second midcourse correction burn, engineers have now successfully completed that burn.

After postponing Juno’s second midcourse correction burn last month, engineers have now successfully completed that burn.

NASA’s Juno spacecraft successfully executed a second Deep Space Maneuver, called DSM-2 last Friday, Sept. 14. The 30 minute firing of its main engine refined the Jupiter-bound spacecraft’s trajectory, setting the stage for a gravity assist from a flyby of Earth on Oct 9, 2013. Juno will arrive at Jupiter on July 4, 2016.

Astronaut Sunita Williams completed first simulated triathlon in space this past weekend on ISS.

Astronaut Sunita Williams completed the first simulated triathlon in space this past weekend on ISS.

After “swimming” half a mile (0.8 km), biking 18 miles (29 km), and running 4 miles (6.4 km), Williams finished with a time of one hour, 48 minutes and 33 seconds, she reported. The space station has its own treadmill and stationary bike, which use harnesses and straps in place of gravity to keep astronauts from floating away. To simulate the swimming portion of the race, Williams used what’s called the Advanced Resistive Exercise Device (ARED) to do weightlifting and resistance exercises that approximate swimming in microgravity.

Three astronauts have safely returned to Earth from ISS.

More important, the Russians have now delayed the next Soyuz manned launch to ISS for a week due to “some malfunctions [that] have appeared in one of the devices of the decent module.”

They also say the delay is to avoid a flight conflict with the next Dragon mission on October 15. This is interesting in that the last word we had from NASA was that the Dragon launch could occur as early as October 5.

Germany announced yesterday that it has approved funding for the design of an in-orbit test of a robot satellite servicing mission.

Germany announced yesterday that it has approved funding for the design of an in-orbit test of a robot satellite servicing mission.

The DEOS project will for the first time demonstrate technologies for the controlled in-orbit disposal of a defective satellite. In addition, DEOS will practice how to complete maintenance tasks – refueling in particular – that extend the service life of satellites. DEOS consists of two satellites, a ‘client’ and a ‘servicer’. The client acts as the satellite requiring maintenance or disposal. The servicer carries out the necessary work on the client. The two satellites will be launched together and brought into orbit at a height of 550 kilometers. According to current planning, DEOS will be ready for launch in 2018.
