NOAA plans use of private weather data

9:56 am

The competition heats up: Mandated by Congress to use commercial weather data obtained from privately launched weather satellites, NOAA has announced its first plan for doing so.

The first Commercial Weather Data Pilot, or CWDP, will kick off this summer with a solicitation for GPS radio occultation data of the sort NOAA and Eumetsat have been using for years to improve weather forecasts. GPS radio occultation receivers that have flown on a handful of research satellites and the U.S.-Taiwanese COSMIC constellation obtain highly detailed temperature and humidity soundings by observing tiny distortions of U.S. Air Force GPS signals as they pass through the atmosphere. While the U.S. and Taiwan are preparing to replace the six original COSMIC satellites with the first six of 12 planned satellites slated to launch on a SpaceX Falcon Heavy perhaps late this year, meteorologists would like to see scores of additional GPS radio occultation satellites in orbit.

Several companies, including GeoOptics, PlanetiQ and Spire, have announced plans to address that demand by deploying constellations of dozens to hundreds of small satellites equipped with GPS radio occultation receivers. Spire launched its first four operational satellites last September.

If this goes as I hope, private companies will launch enough satellites to provide the data, at a far lower cost than NOAA spends to build and launch its own satellites, so that eventually it will not pay for the government to do it anymore. Just as private space is replacing NASA in supplying crew and cargo to ISS, private space can do the same for NOAA.

And like NASA initially, NOAA’s managers have been very reluctant to allow this to happen, as it will eventually take the business from them and give it to others. Since they, like NASA, can’t do it very efficiently, however, they can’t really argue their case very well, which is why Congress has been forcing their hand.

French court rules against freezing Russian assets

9:38 am

In a complicated court battle involving multiple courts, multiple nations, multiple companies, and multiple industries (including Roscosmos), a French court has ruled in favor of Russia and against the shareholders of the liquidated Russian Yukos oil company.

The Ivry First Instance Court ruled in favor of Roscosmos in a dispute with Cyprus-based offshore company Veteran Petroleum, a shareholder in the former Yukos oil company, according to Roscosmos. “They have acknowledged that our arguments are correct and that there is no need to seize the money,” Roscosmos representative Igor Burenkov told the TASS news agency.

France has seized Russian assets worth $1 billion in total following the Kremlin’s refusal to pay damages to former Yukos shareholders. The seized assets included $400 million owed by French-based satellite provider Eutelsat to the Russian Satellite Communications company and $300 million owned by French space launch provider Arianespace to Roscosmos.

More details here. The dispute here is not just between Russia and the shareholders of Yukos. There is also a battle going on between the Hague International Arbitration Court and the French courts. Whether Russia will be able get its money however remains unclear at this moment.

Japanese Venus probe sends back first science data

9:26 am

In a triumph of engineering, the salvaged Japanese Venus probe Akatsuki has beamed back to Earth its first science data.

After an unplanned five-year detour, Japan’s Venus probe, Akatsuki, has come back to life with a bang. On 4–8 April, the Japan Aerospace Exploration Agency (JAXA) presented the first scientific results from the spacecraft since it was rescued from an errant orbit around the Sun and rerouted to circle Venus, four months ago. These include a detailed shot of streaked, acidic clouds and a mysterious moving ‘bow’ shape in the planet’s atmosphere.

Despite the probe’s tumble around the Solar System, its instruments are working “almost perfectly”, Akatsuki project manager Masato Nakamura, a planetary scientist at JAXA’s Institute of Space and Astronautical Science in Sagamihara, Japan, announced at the Inter­national Venus Conference in Oxford, UK. And if another small manoeuvre in two years’ time is successful, he said, the spacecraft might avoid Venus’s solar-power-draining shadow, and so be able to orbit the planet for five years, rather than the two it was initially assigned.

The timing is also good, since Akatsuki is now the only probe circling Venus, and will be for a number of years, until someone else approves, builds, and launches a mission.

Orbital ATK to launch robotic servicing mission

9:22 am

The competition heats up: Orbital ATK has signed Intelsat to the first contract for a private robotic servicing mission to defunct commercial communications satellites.

Orbital ATK is offering the Mission Extension Vehicle (MEV), a spacecraft designed to rendezvous with a commercial satellite and dock to the nozzle of its apogee kick motor and surrounding adapter ring. The MEV would then take over propulsion and attitude control for the satellite, offering up to five years of extended life.

Intelsat has agreed to be the customer for the first MEV mission, named MEV-1 and scheduled for launch in 2018. MEV-1 will first dock with a retired satellite in a graveyard orbit above stationary orbit to test its systems, then dock with an active Intelsat satellite to extend its life for five years.

I like the concept. Unlike other much more complicated proposals, which propose to actually refuel the satellite’s original tank, this is simple, quick, and quite doable for relatively little developmental cost. Orbital ATK already as the technology to do the rendezvous, from its Cygnus freighter. All they need to refine is the specific technology to attach to the specific satellites.

Aerojet Rocketdyne pitches its AR1 rocket engine to reporters

9:15 am

The competition heats up: At a space conference this week Aerojet Rocketdyne pitched its AR1 rocket engine, still under development, as the ideal replacement for the Russian engine in the Atlas 5.

The U.S. Air Force awarded Aerojet Rocketdyne a contract in February worth up to $534 million over five years to certify and start delivering flight-ready AR1 engines in 2019. Aerojet Rocketdyne says it already has kicked in $70 million, with its total investment expected to exceed $250 million over the life of the contract.

Van Kleeck, vice president of Aerojet Rocketdyne’s advanced space and launch business unit, said the Air Force contract — the largest of several propulsion-related awards the service has made in recent months — is a sign of the Air Force’s confidence in the AR1’s ability to provide an expedient replacement for the RD-180 engine the Defense Department is under pressure from Congress to stop using.

United Launch Alliance, however, has anointed Blue Origin’s methane-fueled BE-4 engine as the front runner to replace the RD-180 by serving as the main engine for the Denver company’s next-generation rocket Vulcan.

“The AR1 engine can fly both on an Atlas and Vulcan and it’s the only engine that can do so,” Van Kleeck said.

Aerojet has been losing business to the newer commercial space companies like Blue Origin, and desperately needs to find a customer for the AR1. In the long run the Air Force contract won’t suffice, as it really is no more than government corporate welfare and cannot sustain them as a company. This press conference was part of that effort.

Swiss company buys jet for vomit-comet

9:06 am

The competition heats up: A Swiss company has purchased an Airbus wide-body jet for use as a commercial zero gravity vomit comet.

What makes this different than previous zero-g companies is that they plan to fly a lot of people for a reasonable amount of money.

Prices range from 2,700 Swiss francs ($2,826) for a seat in the “party zone” with up to 40 passengers to as high as 65,000 francs for the VIP Room, which will hold up to 12 passengers, who will also get a luxury watch and can keep their flight suit.

Russian billionaire backs interstellar project

9:00 am

The competition heats up: A Russian billionaire has announced a $100 million investment in an effort to use lasers to propel cellphone-sized spacecraft on an interstellar voyage to Alpha Centauri.

Called Breakthrough Starshot, the programme is based on an idea that has been around for decades: the solar sail. The theory is that a lightweight space sail could harness the momentum carried by photons in order to travel without fuel.

The Breakthrough Starshot team is betting that a burst of concentrated lasers, fired from the ground, could rapidly accelerate a mobile-phone-sized device equipped with microelectronics and a tiny sail — providing much more energy than could be harnessed from the Sun. Whereas NASA’s plutonium-powered New Horizons spacecraft took nine years to reach Pluto, the “nanocraft” envisioned by Breakthrough Starshot would pass by the dwarf planet and exit the Solar System in three days.

The project’s initial US$100-million budget covers only research and development of such a spacecraft. But Breakthrough Starshot’s ultimate goal is to demonstrate proof of concept for an international programme that would send a fleet of nanocraft into space. Doing so would require the group to surmount enormous scientific and engineering challenges in developing the necessary laser technology, materials and communications systems.

This technology is related though not identical to an earlier story about using lasers to power spacecraft.

Russian assets in France seized

8:59 am

Russia’s refusal to pay damages in a court case has forced France to seize $700 million owed to Russia’s aerospace industry.

In total, France has seized Russian assets worth $1 billion following the Kremlin’s refusal to pay damages to former Yukos shareholders.

In July 2014, The Hague international arbitration court ruled that Russia must pay $50 billion for expropriating the assets of Yukos. The seized assets include $400 million owed by French-based satellite provider Eutelsat to the Russian Satellite Communications company and $300 million owned by French space launch provider Arianespace to Russia’s Roscosmos space agency, the magazine reported, citing the Shearman & Sterling legal firm which represents the Yukos shareholders.

This story is similar to the Sea Launch court suit by Boeing, whom the Russians owe $300 million. In that case Boeing has moved to block Russia from selling Sea Launch.

Both stories suggest that the Russians are in big financial trouble, partly caused by a lack of understanding of capitalism. In both cases, they formed partnerships with western businesses and failed to realize that those partnerships placed financial obligations upon them. From its Soviet days Russia probably thought they could ignore those obligations if it became inconvenient, and they are now discovering that this is not really possible if they wish to sell their goods to the rest of the world.

I expect Russia’s space industry to increasingly become isolated from the rest of the world market, partly because of these events.

In related news, Roscosmos has revealed that after the initial launch at Vostochny in April, the second launch will not occur until 2017. This indicates that the first launch is merely a face-saving effort to hide the fact that construction is really more than a year behind schedule, not three months.

Universe’s expansion rate contradicts dark energy data

8:42 am

The uncertainty of science: New measurements of the universe’s expansion rate, dubbed the Hubble constant, contradict theoretical predictions based on previous data.

For their latest paper, Riess’s team studied two types of standard candles in 18 galaxies using hundreds of hours of observing time on the Hubble Space Telescope. “We’ve been going gangbusters with this,” says Riess.

Their paper, which has been submitted to a journal and posted on the arXiv online repository on 6 April, reports that they measured the constant with an uncertainty of 2.4%, down from a previous best result2 of 3.3%. They find the speed of expansion to be about 8% faster than that predicted based on Planck data, says Riess. [emphasis mine]

I highlight the number of galaxies used to get this data because I think these scientists, are being a bit over-confident about the uncertainty of their data. The universe has untold trillions of galaxies. To say they have narrowed their uncertainty down to only 2.4% based on 18 is the height of silliness.

But then, the lead scientist, Adam Riess, recognizes this, as he is also quoted in the article saying “I think that there is something in the standard cosmological model that we don’t understand.”
