ESA contract for hypersonic engine research

8:52 am

The competition heats up: The European Space Agency has signed a research contract for 10 million euros with Reaction Engines to build a ground-based prototype of its hypersonic rocket engine.

While ground testing is always necessary, I am not sure what they gain by building a solely ground-based prototype. Hypersonic engines use the oxygen in the atmosphere, much like jet engines. Their operation however is dependent on altitude as well as the speed in which they are traveling, neither of which is easily tested on the ground.

This project is also one part of the United Kingdom’s new space agency program.

European experimental space junk removal mission to launch

4:46 pm

The competition heats up: A European Space Agency mission to test technologies for removing space junk will launch sometime next year.

Presented at the Royal Society’s summer science exhibition this week, and led by the Surrey Space Centre, the systems included a net, harpoon and drag sail, which scientists have incorporated into a test platform for launch into space. The platform will also carry “artificial junk” in the form of small satellites known as CubeSats.

Once the platform is launched into space, a CubeSat will be released. “The CubeSat will be ejected from the platform and then we’ll fire the net at it,” said Forshaw. The CubeSat, hopefully encased in the net, will then fall back towards Earth and burn up. In the case of the harpoon, the researchers have attached a target made of spacecraft material to a carbon-fibre boom that extends from the platform. “When the harpoon impacts it, it is actually going to simulate a real spacecraft being hit,” said Forshaw.

At the end of the mission the third system, a drag sail will be deployed. Attached to the platform, the sail will speed up its return to Earth where it will burn up in the atmosphere. Similar systems have been proposed for future satellites to allow them to be disposed of without leaving space junk.

With the Chinese, NASA, and private companies all developing robotic missions to either clean up space junk or repair satellites, the competition to do this work is going to get very intense in the next decade.

Russia’s continuing weakness in space

8:24 am

In the heat of competition: Russia this week announced new space agreements with both China and Europe.

The first describes a deal whereby Europe will pay Russia to use its Bion capsules to launch life science experiments. In addition, the article notes that Europe will continue its agreement with Russia to launch commercial Soyuz rockets from its Arianespace launchpad in French Guiana.

The second and third stories describe a variety of negotiations between Russia and China, whereby the two countries will work together in a number of ways, including the possibiliity that China will buy the same Russian rocket engine that ULA uses in its Atlas 5 rocket as well as maybe jointly build a heavy lift rocket with Russia. In the second article, Russia’s deputy prime minister Dmitry Rogozin, in touting the excellence of the Russian rocket engine, could not help taunting the United States.

Europe announces a three month delay for Orion service module

10:01 pm

Be still my heart: Delivery of the service module for NASA’s Orion capsule, being built by the European Space Agency, will be three months late due to engineering modifications.

Nico Dettman, head of ESA’s space transportation department, said the delay is partly a result of the fact that several components could not yet be assessed in the full critical design review and need more time to be integrated into the design. Dettman said another issue forcing the delay resulted from a reassessment by NASA of the stresses the service module needs to be capable of handling in orbit. These “in-orbit load” specifications have recently been tightened. But any design modifications will not affect the service module’s core structure, he said. “If it has an impact, it will be limited to the solar array wings, not the structure – nothing where flight hardware has been manufactured that we will have to touch,” Dettman said. “It’s a late modification, but not too late.”

Note that George Bush proposed Orion in January 2004. The first full up test flight, unmanned, is now scheduled for 2018. Thus, they only had 14 years to build this single capsule and service module.

It took NASA less than five years to build the first Apollo capsule and service module, and less than 8 years to fly seven to the Moon. Damn, it took the Allies less than four years to defeat Germany and Japan in World War II. Yet somehow the big government space programs of NASA and ESA can’t build a single manned capsule in less than 14 years.

Doesn’t anyone but me see something wrong with this picture?

Russia and Europe agree to delay next ExoMars mission

5:22 pm

After looking at their schedules the Russians and Europeans have agreed that they cannot meet the schedule to launch the second ExoMars mission by the next launch window in 2018, and have agreed to delay the mission until 2020.

This really isn’t a surprise, since Russia was a late replacement of the U.S. when the Obama administration backed out of the project suddenly. They need time to prepare.

Europe aims for the Moon

9:49 am

The new colonial movement: The head of the European Space Agency (ESA) said in a video interview this week that building a lunar base is their next major goal.

The head of the multinational agency, Johann-Dietrich Woerner, said the village would “serve science, business, tourism and even mining purposes.” In a video interview posted on the agency’s website, Woerner said a permanent lunar base is the next logical step in space exploration. He said the village could replace the International Space Station in the future. The ISS has been continuously occupied since 2000. It was originally set to be decommissioned by 2020, but its operation has been extended through 2024. The agency said it could take 20 years before the technology is ready to make the Moon village happen.

My next words might sound familiar (see the post below), but few technical details were provided in the video. Instead it appears from the article and the actual interview that the focus here is to establish a bureaucracy, not design rockets or spaceships. I suspect Woerner is looking for projects that can justify the existence of ESA and its bureaucracy, not actually build anything. That he thinks it will take 20 years to make it happen, based on our technology today, is strong evidence of this, since the pace of innovation in the past decade suggests instead that such a Moon colony could happen far quicker, once private space starts making real money in orbit.

ExoMars blasts off

8:46 am

The European-Russian Mars orbiter/lander ExoMars was successfully launched on a Proton rocket this morning from Baikonur.

It will still take most of today for the rocket’s Briz-M upper stage to complete several additional engine burns to send the spacecraft on its path to Mars, but the most difficult part of the launch has now passed.

The article does a nice job of summing up Russia’s most recent track record in trying to send spacecraft to Mars, thus illustrating the significance of today’s success:

For Russian scientists, the launch marks the resumption of a cooperative effort with Europe to explore the Solar System, after the failure of the Phobos-Grunt mission in 2011.The launch of the ExoMars-2016 spacecraft will be Proton’s first “interplanetary” assignment in almost two decades. During its previous attempt in November 1996, Proton’s upper stage failed, sending the precious Mars-96 spacecraft to a fiery desmise in the Earth’s atmosphere and effectively stalling Russia’s planetary exploration program for a generation.

Further in the past, during the Soviet era, the Russians tried numerous times to either orbit or land on Mars. Every mission failed. If this mission successfully reaches Mars and lands it will mark the first time the Russians played a major role in a mission to Mars that actually reached its goal and worked.

Europe settles on Ariane 6 design

6:47 pm

The competition heats up? Airbus Safran and the European Space Agency have settled on the design of their next generation rocket, Ariane 6.

It will not be re-usable, and though they say it will be 40-50% cheaper to produce than Ariane 5, it is very clear from the quotes in the article that they are instead depending on trade restrictions to maintain their European customers, even if it costs them a lot more to put satellites in orbit.

For its part, Airbus Safran does not envisage making Ariane 6 recoverable, not in the short term. Mr Charmeau [the company’s CEO] believes that different market conditions apply in Europe and the US, which means there will not be a single, winner-takes-all approach. He cites, for example, the restricted procurement that exists in all major political blocs, which essentially bars foreign rockets from launching home institutional and government satellites. Nowhere is this more true than in the US, but in Europe too there is an “unwritten rule” that European states should use European rockets.

From an American perspective this lazy attitude is fine with me. Let American companies compete aggressively. They will then leave the Europeans and everyone else in the dust.

Europe kicks in money for Dream Chaser

2:54 pm

The competition heats up: NASA’s decision to award Sierra Nevada a cargo contract has triggered a $36 million investment by the European Space Agency (ESA) to build a new docking unit for Dream Chaser at ISS.

Sierra Nevada Corp.’s win of a NASA contract to ferry cargo to the International Space Station will trigger a $36 million investment by the 22-nation European Space Agency following a cooperation agreement to be signed in the coming weeks, ESA said. Once the agreement is signed, ESA will begin work building the first flight model of the International Berthing and Docking Mechanism (IBDM), which Sierra Nevada’s Dream Chaser Cargo System will use to attach itself to the space station.

ESA said it would spend 33 million euros ($36 million) to complete the design of the IBDM and build a flight model for Dream Chaser’s first cargo run. Future IBDMs will be financed by Sierra Nevada, ESA said.

Europe might end its ISS partnership in 2020

9:26 am

Despite agreements by Russia, Canada, and Japan to extend their ISS partnership with the U.S. through 2024, both France and Germany of the European Space Agency (ESA) are having second thoughts and might pull out in 2020 instead.

In separate statements Jan. 4 and Jan. 5, the heads of the French and German space agencies said a detailed study is under way to assess the future operating cost of the station, and whether the cost can be justified given the pressure on near-term budgets.

Pascale Ehrenfreund, chairman of the board of the German Aerospace Center, DLR, which is Germany’s space agency, said DLR would make no promises until after a full review of ISS’s value. “In view of the high cost involved and the resulting implications on budgets of [European Space Agency] member states, we have to evaluate very carefully costs and benefits of a continued participation in the ISS,” Ehrenfreund said in a Jan. 5 statement in response to SpaceNews inquiries. “It’s only based on this evaluation that we will be able to take a definite position.”

Germany has been Europe’s ISS champion — its biggest paymaster and most vocal booster — for more than 20 years and at times has had to strong-arm France into boosting its support under threat of reduced German backing of Europe’s Ariane rocket program, a French priority.

Eventually, all the partners running ISS with the U.S. are going to come to this decision, which means the U.S. government should begin thinking about what it does at that time. I say, when that time comes the government will privatize the station, giving it to the private companies best able to make a profit from it. And by 2024 the U.S. is likely to have a number of companies quite capable of doing so, from SpaceX to Blue Origin to Bigelow.

There also will be no reason to destroy the station at that time. Being modular, much of it is relatively new, and what is old could be replaced with relatively simplicity. This is a national asset that should not be abandoned nonchalantly.
