Recognizing the competition: In a speech in Singapore, the head of Arianespace said that the company urgently needs to overhaul its Ariane 5 rocket in order to meet tough competition from SpaceX and Russia’s Proton rocket.

“We have a newcomer in America with SpaceX. Yes, competition is increasing, but when competition is increasing, we need to be more and more agile,” said Israel. While recognising that Arianespace was the market leader, “we have to ask ourselves one question: what should we do to remain the leader? Europe is very serious about launchers, and Europe will not give up when it comes to launchers.”

For Arianespace this speech is a very good thing, as it demonstrates again that Israel — and the company — are aware of the competitive challenge put forth by SpaceX and are not making believe it doesn’t exist.

The late arrival of Russia’s first private satellite

8:43 am

The competition heats up? The Dnepr rocket launch of 37 satellites yesterday also included the launch of the first private Russian satellite.

TabletSat-Aurura owned by the company SPUTNIX weighs 26.2 kg and is made to operate for one year. It is intended for remote Earth sensing in the interests of a private company. The satellite was made using Russian technologies and a minimum of foreign components. Its cost is about one million US dollars.

Igor Komarov, the head of the United Rocket and Space Corporation, said “the launch of Aurora, the first Russian private satellite, is a successful example of public-private partnership in the field of space exploration as private companies clearly cannot fulfill their strategic tasks without the state. ,,, I am confident that cooperation between the state and private aerospace agencies in designing and manufacturing high-tech craft will become an important stimulus for further development of Russian competitive technologies.”

SPUTNIX Director-General Andrei Potapov said his company’s plans included “creating a cluster of small spacecraft and craft for super high-definition aerial video surveying and imaging with a resolution of down to one meter per pixel”. [emphasis mine]

Why do I have doubts about this Russian achievement? The reasons are twofold.

Groundbreaking — the literally blasting off of a mountaintop — took place today in Chile at the eventual site of the European Extremely Large Telescope (E-ELT).

Groundbreaking — the literally blasting off of a mountaintop — took place today in Chile at the eventual site of the European Extremely Large Telescope (E-ELT).

Once completed in 2024 this telescope will have a segmented mirror with a total diameter of 39 meters or 128 feet, the largest ever built.

Why the Redskins trademark ruling should terrify you.

Why the Redskins trademark ruling should terrify you.

This ruling isn’t a slippery slope. It’s a slope we’ve already slid down: bureaucrats in Washington are now empowered to make subjective decrees about what is offensive and what will be tolerated, based on pressure from a small clique of Washington insiders. Anyone who runs afoul of these decrees, anyone branded as regressive and politically incorrect, is declared outside the protection of the federal government.

And what do we call people who like to wield that kind of oppressive power? I call them fascists. They hate it when I do that, but I am actually not name-calling but applying a very accurate description to their behavior.

At hearings in the Senate Ted Cruz (R-Texas) sharply attacked the proposed Democratic proposal to amend and restrict the first amendment of the Bill of Rights.

Cruz even offered to replace the Democratic proposal, which would allow Congress to limit spending on political campaigns, with the first amendment itself. All the Democrats rejected that change, illustrating that they reject the first amendment itself.

Two low-cost, car battery-sized Canadian space telescopes were launched successfully in Russia today

10:14 am

Two low-cost, car battery-sized Canadian space telescopes were launched successfully in Russia today.

The important detail here is this quote:

“BRITE-Constellation will exploit and enhance recent Canadian advances in precise attitude control that have opened up for space science the domain of very low cost, miniature spacecraft, allowing a scientific return that otherwise would have had price tags 10 to 100 times higher,” [emphasis mine]

Most nanosats and cubesats have not had the kind of precise attitude control of larger satellites, which is one of their limitations. If the technology is now maturing so that these tiny satellites can be pointed as accurately as bigger payloads, it will mean that unmanned satellites are going to get smaller very quickly. This lowers cost and increases the customer base, creating more business for launch companies.

Rosetta’s comet has unexpectedly gone to sleep.

10:04 am

Rosetta’s comet has unexpectedly gone to sleep.

An image snapped earlier this month by ESA’s Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects. The picture was captured on 4 June by Rosetta’s scientific camera, and is the most recent full-resolution image from the narrow-angle sensor. It has been used to help fine-tune Rosetta’s navigation towards comet 67P/Churyumov–Gerasimenko, which was 430 000 km away at the time.

Strikingly, there is no longer any sign of the extended dust cloud that was seen developing around nucleus at the end of April and into May, as shown in our last image release. Indeed, monitoring of the comet has shown a significant drop in its brightness since then.

Rosetta’s approach for the next few months and arrival at the comet in August should be quite exciting.

SpaceX today released a new video of the most recent Falcon 9R vertical take-off and landing test flight.

9:47 am

The competition heats up: SpaceX today released a new video of the most recent Falcon 9R vertical take-off and landing test flight.

Video below the fold. The flight was to test the deployment and use of fins for controlling the stage during its return to Earth. Watch them unfold and adjust themselves beginning at about 1:15 into the video. In the second half you can see them near the top of the stage.

The new Russian rocket Angara is now scheduled for its first test launch on June 27.

The competition heats up: The new Russian rocket Angara is now scheduled for its first test launch on June 27.

According to the article this decision will be finalized tomorrow. The flight itself will be suborbital. The article also provides a wealth of information about the history, development, and configuration of this rocket. Very worthwhile reading.
