The UAE plan to tow an iceberg from Antarctica for drinking water

The United Arab Emirates (UAE) has a project to tow an iceberg more than 5,500 miles from Antarctica in order to provide that arid nation drinking water for about five years.

The National Advisor Bureau, headquartered in Masdar City, Abu-Dhabi, plans to source the massive blocks of ice from Heard Island, around 600 miles (1000 kilometres) off the coast of mainland Antarctica. It will then transport them around 5,500 miles (8,800 km) to Fujairah, one of the seven emirates which make up the UAE. One iceberg could provide enough for one million people over five years, according to the company.

And the scheme could begin as early as the start of 2018.

SpaceX to launch Bulgarian satellite in June with used first stage

Capitalism in space: SpaceX will fly its second used first stage in June when it launches a Bulgarian communications satellite.

In a statement, BulgariaSat said its BulgariaSat-1 spacecraft is scheduled to launch in mid-June on a Falcon 9 from Cape Canaveral, Florida. The first stage of that Falcon 9 will be the same one that launched 10 Iridium Next satellites from Vandenberg Air Force Base in California in January. Maxim Zayakov, chief executive of BulgariaSat, said the use of a reused first stage lowers the launch price and “makes it possible for smaller countries and companies to launch their own satellites.”

The company did not disclose the price it is paying for the launch, including what discount it is receiving for using a “flight-proven” first stage.

Previously SpaceX had said it would charge about $40 million for a launch using a previously flown first stage, so I would suspect the discount is somewhere around that.

China’s space managers now dominate China’s government

Link here. The story describes how a number of prominent managers from that country’s space program have all been promoted into important political positions throughout the government.

Giving new meaning to the term high-flier, four aerospace engineers have become provincial governors in the past four years. … Until five years ago the quartet worked at either CASTC, a state-owned group that has spearheaded the technological development behind China’s ambitious space exploration programme – producing the country’s rockets, satellites and missiles – or the China National Space Administration, which is in charge of that programme.

In the past, provincial governors were predominantly selected from the ranks of those working in local government or the heads of prominent ministries. The political rise of a group with similar backgrounds has usually been linked to the power of a major faction or influential figure, such as party general secretary Xi.

People who have worked with the former aerospace engineers say the technocrats developed a cocktail of traits that appeared tailor-made to appeal to the current leadership. They did not cook the books, were willing to make necessary but unpopular decisions and were largely untainted by factional allegiances.

Their success also helps explain the increased growth of China’s space program in the past few years. These individuals are all likely to be strong supporters of that space program, and all of them are now very well placed to influence the government in favor of that program.

Trump signs $1 trillion spending bill

Trump today signed the $1 trillion continuing resolution, keeping the government well funded, with no significant cuts, through September.

The article included a detail I had not noticed previously. When the bill passed in the House, the only ones who voted against it were 103 Republicans, while the entire Democratic caucus voted for it. In other words, the Republican leadership screwed their own party and allied themselves with the Democrats to pass this big spending bill that cuts nothing and breaks almost every promise the Republicans and Trump made about spending during the election campaign.

The article also has this very revealing quote from Office of Management and Budget Director Mick Mulvaney:

“I think it’s great that the Democrats like the bill. That’s fantastic.”

As I have said repeatedly, the election in November was nothing more than the Democratic primary, with a choice between a radical socialist (Clinton) and an old fashioned liberal Democrat (Trump). We get the government we deserve.

Bezos sells about $1 billion of his Amazon shares

Capitalism in space: This past week Amazon CEO Jeff Bezos raised about $1 billion in cash by selling 1 million shares of his stock in Amazon.

Amazon.com Inc. Chief Executive Officer Jeff Bezos sold about $1 billion in company stock as part of a planned divestiture, a month after the world’s third-richest man said he spends about that amount annually on his space exploration company Blue Origin LLC.

Bezos sold 1 million shares from Tuesday to Thursday ranging in price from about $935 to $950 per share, according to a regulatory filing on Thursday. He still owns 79.9 million shares, or about 17 percent of the company, down from 83 million shares at the end of 2015.

What this means for Blue Origin is that Bezos has very deep pockets, and will likely be able to finance the development of its very big New Glenn rocket without outside help. That the company will likely also win contracts along the way for the company’s BE-4 rocket engine will also not hurt Bezos’ financial position.

India’s GSLV rocket successfully launches communications satellite

India’s successfully launched a communications satellite early today using its Mark II GSLV rocket.

Friday’s launch, designated GSLV F09, was the fifth flight of the Mark II GSLV which debuted in April 2010. This replaced the Mark I, which first flew in 2001 and made its final flight at the end of 2010, introducing an Indian-developed third stage engine instead of a Russian-built engine flown on the Mark I. With this new cryogenic propulsion system, the GSLV Mk.II is a fully indigenous vehicle.

The GSLV’s service has been marred by concerns over its reliability – to date only half of its flights have been successful – however last September’s launch of INSAT-3DR saw it achieve three consecutive successes for the first time.

This launch success significantly strengthens ISRO’s ability to sell its launch services worldwide. They now have three different rocket configurations, all entirely home built, and all with a string of launch successes.

Senate to ignore House Obamacare replacement, write its own bill

Failure theater: Senate Republicans today said in interviews that they plan to ignore the House Obamacare replacement bill, passed earlier today, and write their own bill from scratch.

A Senate proposal is now being developed by a 12-member working group. It will attempt to incorporate elements of the House bill, senators said, but will not take up the House bill as a starting point and change it through the amendment process. “The safest thing to say is there will be a Senate bill, but it will look at what the House has done and see how much of that we can incorporate in a product that works for us in reconciliation,” said Sen. Roy Blunt, R-Mo.

“We are going to draft a Senate bill,” added Sen. Chuck Grassley, R-Iowa. “That is what I’ve been told.”

I have no faith in what we will get in the end, mainly because it is apparent these guys are not starting from the premise of eliminated the law and its unworkable regulations. Instead, they are proposing, as the House did, to install their own unworkable regulations.

Nancy Sinatra – Sugar Town

An evening pause: I usually dislike most music videos because of their cliches and fakery, preferring live performances instead. However, this 1967 Nancy Sinatra music video, from the very early days of such things, is so simple it doesn’t bother me that much. In a sense, it even highlights the music.

Hat tip t-dub.

Curiosity’s last dune investigation

As Curiosity moves closer to the very base of Mount Sharp, it is presently making its last investigation of the various types of dunes found at the foot of the mountain.

From early February to early April, the rover examined four sites near a linear dune for comparison with what it found in late 2015 and early 2016 during its investigation of crescent-shaped dunes. This two-phase campaign is the first close-up study of active dunes anywhere other than Earth.

Among the questions this Martian dune campaign is addressing is how winds shape dunes that are relatively close together, on the same side of the same mountain, into different patterns. Others include whether Martian winds sort grains of sand in ways that affect the distribution of mineral compositions, which would have implications for studies of Martian sandstones. “At these linear dunes, the wind regime is more complicated than at the crescent dunes we studied earlier,” said Mathieu Lapotre of Caltech, in Pasadena, California, who helped lead the Curiosity science team’s planning for the dune campaign. “There seems to be more contribution from the wind coming down the slope of the mountain here compared with the crescent dunes farther north.”

The article also included a vague update on the status of Curiosity’s drill, out of commission since its drill feed mechanism had problems moving the drill up and down back in the fall of 2016.

Engineers are assessing how the use of vibration to deliver samples may affect the drill feed mechanism, which is used to move the drill bit forward and backwards. In addition, high winds at the linear-dunes location were complicating the process of pouring sample material into the entry ports for the laboratory instruments.

“A balky brake appears to be affecting drill feed mechanism performance,” said Curiosity Deputy Project Manager Steven Lee, of NASA’s Jet Propulsion Laboratory, Pasadena, California. “In some cases, vibration has been observed to change feed effectiveness, so we’re proceeding cautiously until we better understand the behavior. In the meantime, the engineering team is developing several methods to improve feed reliability.”

What this release does not say is whether they are any closer to solving the problem, or whether the drill is essentially out of business for the reminder of Curiosity’s life. To me, the silence on this question is deafening, and strongly suggests that they have decided the drill cannot be used, for the foreseeable future.

Senate passes $1 trillion continuing resolution 79-18

With friends like this, who needs enemies? The Republican Senate today passed the $1 trillion continuing resolution that contains none of the promised cuts to the federal budget promised by the Republican Party and by Donald Trump.

The vote was 79-18. The resolution now heads to the White House, where Trump is expected to sign it eagerly.

A look at the names in the Senate who voted against this bill essentially lists the few remaining real conservatives left. Such people are now a minority, surrounded by corrupt deal makers who have no interest in the needs of the nation.

Republican Trumpcare passes House

The Republican-controlled House today passed a replacement healthcare bill that would not repeal Obamacare but merely tinker with it around the edges.

Anyone who thinks this is an Obamacare repeal is fooling themselves. A repeal would be very simple. The details of this new bill are so complicated that I have not been able to figure them out, even after reading numerous articles, both pro and con, about them. In other words, should this bill get past the Senate it will do little good, and will only allow the collapse of the health insurance industry to continue.

Getting this past the Senate is another story. It looks like the plan here was to pass it in the House, so these creeps could lie and claim they passed an Obamacare repeal, and then have the Senate kill it for them.

New poll suggests majority of Americans support free speech

A new poll has found that while a large minority of registered voters approve of banning offensive speakers from college campuses, a majority still support the idea of a free and open society.

Below the fold is the entire poll [pdf] for this particular question, with the poll results broken down across a wide selection of demographic groups. Except for only a handful of such groups, which I have highlighted, Americans across the board continue to support the idea of free speech, though the large minorities are certainly worrisome. Then again, I have seen polls like this for most of my life, and the news story routinely focuses in on the large minorities that favor restricting free speech, as does the story at the link above. Such minorities have always existed, however, and sometimes there are even circumstances where they are right!

The question isn’t whether they are there. The questions should be: What are the trends? And are those who are hostile to free speech concentrated in any single demographic group that holds power?

So, what are those handful of demographic groups where a plurality favors banning speakers? Not surprisingly, those groups are Democrats, Democratic women, African-Americans, homemakers, those who do not have an identifiable job, and those who consider Medicare and Social Security to be the #1 issue facing the nation. Essentially, these groups form the heart and soul of the modern Democratic Party, which appears increasingly to also be the home of people who are hostile to freedom and wish to restrict it. This fact helps explain why the Democrats in the last Congress actually proposed an amend to the Constitution that would have partially repealed the first amendment, allowing Congress to restrict speech.

If you are Democrat and support free speech, you should be aware of this, either to change your party, or to consider leaving it. I tried the first when I lived in New York, failed, and thus was forced to chose the second. I have never looked back.

California proposes taxes on commercial space companies

We’re here to help you! The Franchise Tax Board of California has proposed new regulations that would allow the state to tax commercial launch companies.

You can read the full proposal here [pdf].

The rules are designed to apply to any company operating in California that generates at least half the money it takes in from “space transportation” — defined as the movement of people or property 62 miles above the surface of the Earth. That’s the internationally recognized line that separates our planet from the rest of space. It would apply to companies that use California as a launchpad, not California companies launching from other states, like Texas or Florida.

Essentially, they will tax any launch from Vandenberg, basing the tax on the distance the payload flies while still attached to the rocket and still the responsibility of the launch provider.

This is essentially a tax on SpaceX, since they are California’s only major launch company. This is also a tax on Vandenberg, the only spaceport in the state. The result? Expect future companies to flee California. Expect new spaceports to spring up elsewhere. As noted in the article:

At least one company has already been lured away from California for the promise of greater financial incentives — though of a more earthly variety. Moon Express, a company working to mine the moon for natural resources, moved from Mountain View to Florida. In an email, the company’s CEO and founder, Bob Richards, said the company “relocated from California to Florida in part due to the State of Florida’s progressive economic development incentives designed to attract commercial space companies

3D printing of bricks, using moondust

European engineers have managed to print bricks using simulated moondust and focused sunlight.

The resulting bricks have the equivalent strength of gypsum, and are set to undergo detailed mechanical testing. Some bricks show some warping at the edges, Advenit adds, because their edges cool faster than the centre: “We’re looking how to manage this effect, perhaps by occasionally accelerating the printing speed so that less heat accumulates within the brick. But for now this project is a proof of concept, showing that such a lunar construction method is indeed feasible.”

The video at the link is very unconvincing. While it shows film of the printing process, it does not show film of anyone holding or manipulating the finished bricks. Instead, it shows one or two photos of finished bricks, all of which give the impression that these bricks crumble easily at the edges, I suspect that the bricks are simply too fragile for practical use.

So, is this a proof of concept? Maybe. They have at least shown that 3D printing using materials on the Moon might work.

Cassini science team releases movie of images from first ring dive

The Cassini science team has released a movie compiled from images taken during the spacecraft’s first dive between Saturn and its rings.

I have embedded the movie below the fold. It cuts off before the spacecraft’s closest approach because they took a very conservative approach to this fly-by, turning the vehicle so that its antenna dish protected it. This prevented the taking of the best images. The second dive, that occurred yesterday, will have better images.

Maiden flight of China’s new 158-seat C919 passenger jet

China’s answer to Boeing and Airbus’s domination of the aviation business, a 158-seat passenger jet dubbed C919, is due to make its maiden flight later this week.

According to Xinhua, the first flight of the C919, assembled by state-owned Commercial Aircraft Corporation of China (Comac), will be conducted at the Shanghai International Airport on Friday, but could be delayed if weather conditions are not suitable. The timing for the first flight was set after the passenger jet passed a thorough assessment in April.

A successful maiden flight, followed by a series of safety certification processes, could open a floodgate for new orders for the single-aisle passenger jet, likely to generate 1 trillion yuan (HK$1.13 trillion) in business for Comac, according to Galaxy Securities. The C919 has received 570 orders and commitments from 23 customers, mainly Chinese state-owned carriers and leasing companies.

The plane is three years behind schedule. And while much of it is Chinese-made, a considerable percentage of major parts are produced by U.S. and European manufacturers.

Submarine test launch by Iran of cruise missile fails

How’s that Iran deal working out for you? An Iranian test launch of a cruise missile from a submarine yesterday appears to have been a failure.

Iran attempted to launch a cruise missile from a submarine in the Strait of Hormuz on Tuesday but the test failed, two U.S. officials told Fox News. An Iranian Yono-class “midget” submarine conducted the missile launch. North Korea and Iran are the only two countries in the world that operate this type of submarine.

In February, Iran claimed to have successfully tested a submarine-launched missile. It was not immediately clear if Tuesday’s test was the first time Iran had attempted to launch a missile underwater from a submarine.

This test is not surprising, considering that it also appears that Iran is using the billions they obtained from the Obama administration as part of the nuclear deal to fund a massive military buildup.

Iranian officials announced late last month that Iran’s defense budget had increased by 145 percent under President Hassan Rouhani and that the military is moving forward with a massive restructuring effort aimed at making it “a forward moving force,” according to regional reports.

Iranian leaders have stated since the Iran deal was enacted that they are using the massive amounts of cash released under the agreement to fund the purchase of new military equipment and other armaments. Iran also has pursued multi-million dollar arms deals with Russia since economic sanctions were nixed as part of the deal.

But hey, what’s a few bombs between enemies, eh?

The soft avalanches of Mars

Krupac Crater gullies

Cool image time! The image on the right, reduced in resolution to show here, shows the gullies flowing down Krupac Crater on Mars. Be sure to check out the original, released today by the Mars Reconnaissance Orbiter science team, since they have enhanced the colors to bring out the sandy flows, noting as well that while most of these gullies are found in higher latitudes, this crater at 7.8 latitude has them as well.

Although large gullies (ravines) are concentrated at higher latitudes, there are gullies on steep slopes in equatorial regions. An enhanced-color closeup shows part of the rim and inner slope of Krupac Crater located just 7.8 degrees south of the equator.

The colors of the gully deposits match the colors of the eroded source materials. Krupac is a relatively young impact crater, but exposes ancient bedrock. Krupac Crater also hosts some of the most impressive recurring slope lineae (RSL) on equatorial Mars outside of Valles Marineris.

Below I have cropped out a small section showing, at full resolution, the termination point of one of these flows, indicating where this section is on the larger image to the right. This avalanche is clearly not liquid, though it has a very sandy and soft nature, suggesting — as some scientists have theorized — that liquid from below the surface might have played a part in its flow.

It is important in looking at these images to repeatedly remind yourself that the gravity here is about one third that of Earth, and thus the angle of repose will be different, and that avalanches will behave very differently in this environment. Moreover, Mars’s far colder climate will also effect things. The avalanche we are looking at could not happen in this way on Earth.

NASA looks to private companies for lunar missions

Capitalism in space: NASA has issued a request for information on possible private commercial missions capable of carrying NASA payloads to the Moon.

From the announcement:

NASA has identified a variety of exploration, science, and technology demonstration objectives that could be addressed by sending instruments, experiments, or other payloads to the lunar surface. To address these objectives as cost-effectively as possible, NASA may procure payloads and related commercial payload delivery services to the Moon

In other words, NASA has money to spend on lunar science missions, and rather than plan those missions itself, as it has done since the 1960s, it is now offering to buy and launch proposals from private companies.

Iran announces launch plans for 2018

Iran’s Aerospace Research Instititue (ARI) has announced that it plans to launch its Nahid-2 communications satellite in 2018.

Interestingly, Iran’s first Nahid communications satellite, Nahid-1, has missed its announced March 2017 launch date. Worse, that satellite had been first scheduled for launch in 2012. Similarly, a remote sensing satellite that was supposed to have been launched in the early part of this year, Dousti, has also been delayed.

ISRO requests Indian proposals for Venus probe

India’s space agency ISRO has issued a request for proposals from Indian scientists for the scientific instruments to be installed on a future probe to Venus.

The announcement included the following information about the proposed Venus orbiter itself:

The payload capability of the proposed satellite is likely to be 175 kg with 500W of power. However these values are to be tuned based on the final configuration. The proposed orbit is expected to be around 500 x 60,000 km around Venus. This orbit is likely to be reduced gradually, over several months to a lower apoapsis.

All told it appears that India is moving forward with this project, and probably intends to build it much like they build Mangalyaan, their successful Mars orbiter, quickly, efficiently, and for relatively low cost.

Company that analyzes satellite data raises $50 million

Capitalism in space: Orbital Insight, a company that uses computers to analyze satellite imagery of the Earth, has raised $50 million in new investment capital.

The fresh capital will be used to expand its partnerships, increase its analytics products, and build bigger international sales operations in Europe and Asia, Orbital said. The Mountain View, California-based company founded by former NASA scientist and Google engineer James Crawford also will step up recruiting in engineering, data science and design.

Falling satellite launch costs are helping make geospatial imagery a bigger and better source for economists and investors tracking everything from China’s manufacturing to the number of cars parked outside Wal-Mart stores. Venture capital investment in space companies jumped to a record nearly $1.4 billion last year, bringing the total since 2000 to $13.3 billion, Goldman Sachs Group Inc. said in a report last month. [emphasis mine]

Nor are the lower launch costs hurting the launch industry. Instead, the industry is booming, as it now has a lot more customers available to buy their launch services.

Astronomers find that Epsilon Eridani solar system resembles our own system

New data of the Epsilon Eridani solar system 10.5 light years away confirms that its debris disk has a structure somewhat resembling our own solar system.

The data has found that the debris disk has two narrow belts, one located at about the same distance from the star as our asteroid belt, and the other orbiting at about where Uranus is located. In addition, the system appears to have a Jupiter-sized planet orbiting the same distance from the star as does Jupiter.
