Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.

3:57 pm

Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.

[Rosetta] woke yesterday as planned, to the relief of ESA scientists – but the signal it sent home to confirm it was awake reached Earth late, fraying the nerves of some mission controllers in the meantime. Due to call at 1745 GMT, Rosetta did not announce its revival until 1818. Fifteen minutes could be explained because the spacecraft’s computer checked the on-board clock only every quarter of an hour. The additional 18 minutes, however, was a mystery.

Now, the telemetry has shown that soon after Rosetta’s first revival sequence had started, the on-board computer automatically rebooted and the sequence started again, causing 18 minutes of delay.

It seems all is well now, though the engineers plan to spend some time pinpointing the cause of the reboot.

The European Space Agency has now released its first cost estimates for upgrading and replacing its Ariane 5 rocket.

The European Space Agency has now released its first cost estimates for upgrading and replacing its Ariane 5 rocket.

Europe needs to find about 1 billion euros ($1.35 billion) to complete development of an upgrade to its current Ariane 5 heavy-lift rocket, which would fly in 2018 and be capable of lifting satellites weighing 11,000 kilograms into geostationary transfer orbit, European Space Agency Director General Jean-Jacques Dordain said Jan. 17. The Ariane 5 upgrade, called Ariane 5 ME, will be on the table for ESA governments to decide, alongside the new Ariane 6 rocket, at a meeting scheduled for December in Luxembourg.

In a press briefing in Paris, Dordain said it is too early to say how much Ariane 6 will cost to develop. Government and industry estimates have ranged between 3 billion and 4 billion euros, with an inaugural flight in 2021.

As Doug Messier notes in his worthwhile analysis of these numbers, “Europe is in deep trouble.” From a customer’s perspective, these new rockets won’t fly (pun intended). The cost is too high and the development time too long. By the time they get both Ariane 5 and Ariane 6 ready for launch they will be obsolete and overpriced, when compared to the rocket’s that will already be available from their competitors.

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.

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.

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.

Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.

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.

For its next science mission the European Space Agency (ESA) has now decided to give first priority to an X-ray space telescope.

They have demoted a space-based gravity wave detector to second place. As is typical for ESA, the pace here is quite slow, as both missions are now scheduled for launch in 2028 and 2034, decades away.

Europe turns off Planck

8:32 am

Europe turns off Planck.

Planck operated four-and-a-half years, three times longer than originally planned. Launched in May 2009 on an Ariane 5 rocket shared with ESA’s Herschel telescope, Planck measured the cosmic fingerprint of the Big Bang, detecting subtle variations in background light originating 380,000 years after the genesis of the universe.

Europe has successfully drop tested its experimental re-entry vehicle.

Europe has successfully drop tested its own experimental re-entry vehicle.

The full-scale Intermediate eXperimental Vehicle (IXV) prototype was released from an altitude of 3000 m by a helicopter, falling to gain speed to mimic a space mission before parachute deployment. The parachute slowed IXV for a safe splashdown in the sea at a speed below 7 m/s. This last step in a series of tests shows that IXV can be recovered safely after its mission into space.

Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.

Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.

The Spaceflight101 portal said the delay was due to possible “mold and bacteria contamination on three cargo bags that are inside the spacecraft” and that a decision is yet to be made on whether the crew should use anti-mold kits to clean ATV-4 cargo before taking it inside the ISS.

The Russians had a lot of problems with mold in their early Salyut space stations, and understand the unpleasant consequences should mold spread into the station. Thus, I am not surprised if they are taking this issue seriously.

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 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.

9:17 am

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.
