SpaceX chooses recovered first stage to reuse

The competition heats up: SpaceX has chosen as the first Falcon 9 first stage to reuse the one that was the first to land successfully on a barge on April 8.

Though they have not announced the mission it will fly, I strongly suspect it will be one of the two SES communications satellites scheduled to launch in the fall. SES has already said they want to buy a launch using a re-used first stage, and the two SES satellites scheduled for the fall have some redundancy between them.

Getting and Installing Linux – Part 4

The Software Manager

by James Stephens

A computer is nothing more than a toy unless it has the tools you need to get your work done, and Linux has a great set of tools. Most distributions come loaded with the tools most people use every day, a full office suite, graphics and media packages and so on. If you want more, a world of software awaits at your fingertips via the Software Manager. Think of it as the app store for your distribution, with tens of thousands of official titles vetted and available for download, most free of charge. No longer are you left to the wilds of the Internet to find what you need.

Most Linux Software is functionally equivalent to that of Apple or Windows. Most open source titles are ported to all platforms including Linux. So if you use an open source title such as Audacity or VLC media player, just type its name into the Linux Software Manager search bar and you will find it. For propitiatory titles such as Photoshop just define what it does, image manipulation for example, and the Software Manager will suggest Linux equivalents like GIMP or KRITA. In addition Photoshop and some other Windows software run great on Linux using WINE – the Windows compatibility layer. More about that later.

A brief history of the nuclear defence triad

Link here.

The essay is a fascinating look at the origins in the 1950s of the U.S.’s defense triad of ground-launched ICBMs, submarine-launched ICBMS, and bombers. The section on the history of ICBMs describes nicely the roots of the Atlas 5 rocket as well as many of the federal government’s contracting policies for its big government projects like SLS.

You can’t just call up a new weapons system from nothing by sheer will alone. As [Thomas Hughes, in his history of Project Atlas] explains, there were severe doubts about how one might organize such a work. The first instinct of the military was to just order it up the way they would order up a new plane model. But the amount of revolutionary work was too great, and the scientists and advisors running the effort really feared that if you went to a big airplane company like Convair and said, “make me a rocket,” the odds that they’d actually be able to make it work were low. They also didn’t want to assign it to some new laboratory run by the government, which they felt would be unlikely to be able to handle the large-scale production issues. Instead, they sought a different approach: contract out individual “systems” of the missile (guidance, fuel, etc.), and have an overall contractor manage all of the systems. This took some serious effort to get the DOD and Air Force to accept, but in the end they went with it. [emphasis mine]

Sounds remarkable like the way the SLS rocket program is organized, with different contractors building different engines and stages and one contractor (Boeing) acting as top manager. More interestingly, the way the military used to do things — put out a request and let the private sector build it — is similar to the way NASA is doing things in today’s commercial cargo/manned program. What forced the transition from having the private sector design things to having the government entirely in charge? I have highlighted the key phrase, “the scientists and advisors running the effort.” They might have been sincere and they might even have been right, at the time, but nonetheless their approach was still a power grab, taking control of design and construction from the private sector and shifting it to them and the government entities building the rockets.

When construction actually started, the government ended up with six different rocket programs, Redstone, Atlas, Thor, Titan, Polaris, and Minuteman.

The redundancy was a hedge: the goal was to pick the top two of the programs and cancel the rest. Instead, Sputnik happened. In the resulting political environment, Eisenhower felt he had to put into production and deployment all six of them — even though some were demonstrably not as technically sound as others (Thor and Polaris, in their first incarnations, were fraught with major technical problems). This feeling that he was pushed by the times (and by Congress, and the services, and so on) towards an increasingly foolish level of weapons production is part of what is reflected in Eisenhower’s famous 1961 warning about the powerful force of the “military-industrial complex.”

Once again, this history illustrates the power grab that took place in Washington in the 1950s, something that Eisenhower did not like. Sixty years later, the rocket industry is struggling to transition back to the old way of doing things, because it actually works better. Before the 1950s, our innovative, competitive, and fast moving technological private sector made the United States an unbeatable powerhouse. Afterward, we increasingly lost the ability to innovate and compete, because the system created by these scientists and advisors did not encourage competition. Instead, they instituted a top-down centralized command approach, ironically quite similar to the Soviet model, the very philosophy the United States was opposing during the Cold War.

The failures of that top-down approach — illustrated starkly by SLS’s gigantic budget, interminable delays, and little produced — might finally be coming home to roost, allowing a new power grab by a competitive private sector. The change I think will be generally beneficial, not only to the needs of the federal government but to the needs of the general population, as it will generate a lot more wealth, a lot more innovation, and a lot more excitement, as it once again makes the U.S. a powerhouse, this time out among the planets.

Want to get a close look at the Russian spaceport during a launch? You can!

The space tourism company that has partnered with the Russians to fly tourists to ISS is now offering a nine-day tour of Russia’s launch facilities, including watching a Soyuz manned launch for the bargain price of $14,495.

Guests will get to see the launch of the Soyuz spacecraft on its way to the International Space Station and experience the live Soyuz-International Space Station docking at Mission Control Center. “We will observe the early morning roll-out of the Soyuz Rocket and follow it to the launch pad site together with the press, military personnel, cosmonauts, and their relatives,” said MIR Corporation President Douglas Grimes. “The following day we will gather in a VIP seating gallery at Mission Control Center for the live satellite feed of the Soyuz docking.”

Guests also have the option to participate in cosmonaut training themselves: They can experience up to 4 Gs on the world’s largest centrifuge, take a parabolic zero-G simulation flight, don a spacesuit, and learn how to handle “typical space tasks.”

SLS engine shuts down prematurely during test

A static firing test of one SLS’s rocket engines, repurposed from the shuttle, ended prematurely on Thursday.

It appears there was “a minor issue with the test stand” that caused the early shutdown. Some history about the engine itself:

The test involved development Engine 0528, back in the test stand at Stennis for its first test firing in seven years. E0528 was last fired from the nearby A-2 stand on July 1, 2009, in the second-to-last Space Shuttle Main Engine (SSME) ground test for the Shuttle program. Now out of storage and ready to fire again, the Aerojet Rocketdyne engine is being used in a second series of tests of the RS-25 configuration that will fly on SLS.

This is a test program, so having things go wrong is not necessarily a problem, as the failure teaches you things you need to know. However, they aren’t supposed to be testing the test stand, they are supposed to be testing the engine.

New Horizons looks back at Pluto

One year after New Horizons’ breath-taking fly-by of Pluto, the science team has written a review of what they have learned.

They list what they consider the mission’s top ten discoveries, which I think can be summed up in one phrase: the uncertainty of science. Pluto was more active geologically and atmospherically than predicted by all models. It was also more complex. Other surprises: Both Pluto and Charon show evidence of sub-surface liquid oceans of water. Charon’s dark red polar baffles them. They unexpectedly found no additional moons, and also discovered that as far as they can tell by the available data, the moons were all formed when Pluto formed, something they also did not expect.

The one thing that I expected that did happen? We got close, and discovered things we had not expected. Be prepared for further surprises when New Horizons flies past Kuiper Belt object 2014 MU69 on January 1, 2019.

Trump rally attendees sue San Jose

Fourteen attendees of a San Jose Trump rally on June 2 have filed a class-action suit against the city, the mayor, and the police chief for their failure to protect them from rioters.

“Law-abiding citizens leaving the Trump rally were victimized by being forced by armed police to walk into a riot in full swing where many were assaulted while police looked on,” said the plaintiffs’ attorney, Harmeet K. Dhillon, who is also the vice chair of the California Republican Party.

Dhillon says her clients range from a 14-year-old who was assaulted by two different individuals and denied assistance by the San Jose Fire Department to a 71-year-old woman whose glasses were ripped off and destroyed by three rioters. She said it was made clear that the “inaction” of 250 San Jose police officers “was colored by political viewpoint considerations.”

As documented at the time, the San Jose police actually arranged things so that the Trump supporters were forced to take a detour that would put them directly in the path of the violent protesters, and then stood down and watched them get attacked.

I hope they win big, and bankrupt the mayor and the police chief.

Route to Balanced Rock

Route to Balanced Rock on Mars

The image above is a panorama I have created from the raw images taken by Curiosity’s left navigation camera today, using this image for the left half and this image for the right half. They show the terrain in front of the rover, including the balanced rock on the horizon, indicated by the arrow.

I have no idea what route the science team plans, but looking at all of the images, as well as their desire to get a closer look at the rock, I suspect they will head up to the left on the smoother ground, aiming almost directly at the balanced rock. I also suspect that they will eventually veer right before getting to the rock, since the rover can’t go over the rough terrain in that area. Stay tuned to find out.

Freedom caucus demands impeachment vote on IRS head

Good news: Despite the opposition of Speaker Paul Ryan (R-Wisconsin), the conservative Freedom Caucus in the House is demanding a vote on the House floor on the impeachment of IRS head John Koskinen.

Two points: First, the vote is not guaranteed, as the motion put forth now will expire during the summer recess. The caucus will have to re-introduce it when Congress reconvenes in September, something they say they will do.

Second, Ryan’s resistance to having this vote does not speak well for him, considering the outrageous stonewalling by Koskinen in connection with IRS scandal, including lying to Congress and participating in the destruction of evidence that had been specifically requested by Congress. It also helps confirm the accusations of Ryan’s opponent in the August 9 Republican primary, Paul Nehlen, that Ryan is not the conservative he claims to be.

Trump picks Pence

It appears that Donald Trump has chosen Indiana governor Mike Pence as his vice presidential running mate.

This article provides a detailed look at Pence’s background, which is decidedly conservative and tightly linked with tea party philosophy.

Trump’s choice here is definitely encouraging. It suggests that his claimed conversion to conservative values might actually be sincere (though clearly shallow), because it suggests he is looking for conservatives to help him figure out how to be a conservative. As I’ve said repeatedly, the best way to make sure Trump governs as a constitutional conservative is to surround him with constitutional conservatives. This choice indicates that he is not going to resist that possibility.

Let me add that picking Pence could help Trump significantly in garnering support from the status quo Republicans that have been resisting him, since these same people respect Pence highly.

Let me also add one cautionary note. I have a memory of Pence at one point waffling on conservative principles for political gain, but I cannot at all remember the context or situation. Thus, it is important to remind ourselves repeatedly that these are all politicians, and that their interest is not necessarily that of the nation’s but of their own self-interest, which means getting elected. At any time they could toss the Constitution in the trash heap if that is what they think will get them votes. UPDATE: This article outlines Pence’s waffling as governor in Indiana, confirming my reservations about him.

It is therefore very important to not only surround Trump with conservatives, all politicians must be surrounded by voters who demand they defend our rights and our freedoms, as defined by the Constitution. Only then can we be reasonably assured that those rights will be defended.

More bright spots on Ceres

More bright spots on Ceres

Cool image time! The most recently released Dawn image of Ceres, cropped on the right, included these bright streaks running down the side of an unnamed crater. They are especially intriguing because they so much resemble the seepage lines scientists have found on slopes on Mars. On Mars the lines appear to come and go on a seasonal basis, while on Ceres they appear to have been caused by a one-time event, after which not much has changed. In both cases, however, they appear to be caused by some liquid seepage that came from below the surface.

DARPA pushes its Experimental Spaceplane program forward

The competition heats up: DARPA outlines its goals for its Experimental Spaceplane program (XS-1).

Key to the effort is DARPA’s recognition that since 2000 under the government’s EELV program, launch costs for the military had increased significantly, while the launch rates appears to slow.

According to DARPA’s presentation, the Pegasus, Minotaur, and Antares launch vehicles only fly one DoD mission per year at a cost of ~$55 million USD per flight.

SpaceX’s Falcon 9 currently performs ~3-6 DoD missions per year at a contract price equal to or greater than $54 million USD per flight.

That price per flight then jumps dramatically for United Launch Alliance’s (ULA’s) Atlas V and Delta IV launch vehicle families – which currently perform about 8 DoD flights per year for a cost per flight in excess of $400 million USD. [emphasis mine]

ULA claims that they charge the Air Force an average of $225 million per launch. DARPA says it is $400 million. Either way, that is a lot higher than the $83 million that SpaceX charged for its first Air Force contract.

The article then provides a nice overview of the XS-1 program, which like NASA’s commercial space program is asking private companies to come up with the new designs and technologies rather than have the government try to do it. All DARPA is doing is laying out their basic requirements, fly 10 times in 10 days for less than $5 million per flight.

The program is now shifting to its second phase, which will call for actual construction proposals late this year, with the hope of test flights by 2019.

Angara’s status

The competition heats up: Work on the factories that will build and assembly Russia’s new Angara rocket appear to be nearing completion.

The article is an excellent overview of the entire Angara program. It also includes a number of interesting nuggets of information that might explain events of the past as well as Russia’s future success or failure of Angara.

For example, the repeated problems with Proton’s Briz-M upper station in 2012 could have been caused by the shift of much of its production from the Khrunichev factories near Moscow to a newly absorbed company located in Siberia. The move was made to take advantage of lower costs in Siberia while letting the company sell off land in Moscow.

Beginning in 2009, PO Polyot was to take responsibility for the production of the Briz-KM upper stage for the Rockot booster, as well as Rockot’s adapter rings and the payload fairings. Also, the manufacturing of all key elements for the Angara-1.2 version of the rocket would end up in Omsk as well. Additionally, the Ust-Katav Wagon-building Plant, UKVZ, would produce components for Angara and its KVTK upper stage, along with sections of the Proton rocket and the Briz-M upper stage.

As for Angara, the article suggests that Russia is struggling to make it as inexpensive to launch as Proton:

Iridium’s next generation constellation of satellites

The competition heats up: Iridium prepares the first 10 of a total of 81 new satellites for launch on SpaceX’s Falcon 9 in September.

The Iridium Next program is a $3 billion investment by Iridium, according to Matt Desch, Iridium’s chief executive officer. Iridium’s purchase of 81 satellites represents approximately $2.2 billion of that cost, Desch said, and the company’s launch contract with SpaceX for seven Falcon 9 flights was valued at $492 million when the parties signed it in 2010. That was the largest commercial launch contract in history until last year’s 21-launch order by satellite Internet provider OneWeb with Arianespace.

The first 10 Iridium Next satellites will fly on a Falcon 9 rocket in September, followed by a second launch as soon as December with the next batch. Iridium managers will give the go-ahead for the second launch once the first 10 satellites finish initial in-orbit tests, Desch said. The other five launches should occur about once every two months next year to fill out the Iridium Next fleet 485 miles (780 kilometers) above Earth. Iridium’s contract with SpaceX calls for all the missions to fly on newly-built Falcon 9s, a situation unlikely to change any time soon since insurance arrangements for the initial launches have been finalized.

But Desch said he is open to purchasing reused Falcon 9 boosters in the future “if they’re the right price.”

To meet this schedule SpaceX’s launch schedule will have to ramp up considerably from its present rate of one launch about every three weeks.

Trump doesn’t care if Republicans hold Senate

Update on the November Democratic primary: Donald Trump was quoted in a news article today that he really doesn’t care that much it the Republicans retain their majority in the Senate.

When I asked him recently whether the party’s maintaining its majority in the Senate meant anything to him, he replied: “Well, I’d like them to do that. But I don’t mind being a free agent, either.” Trump has shown similarly little interest in helping his party’s committees build the sort of war chests typically required in a campaign year. After winning the presidential nomination on a shoestring budget and with fewer paid staff members than the average candidate for governor, he has been visibly reluctant to help build much in the way of national campaign infrastructure, sending a clear message to his fellow Republicans: This fall, you’re on your own. [emphasis in original]

I strongly advice all my readers to read the analysis at the link. From all accounts, Trump’s campaign effort sure does look like he is a Democratic wolf in Republican sheep’s clothing, and that this prediction describing an actual Trump administration will prove amazingly accurate.

Another Obamacare co-op fails

Finding out what’s in it: The third Obamacare co-op in the past two weeks has failed. .

Illinois regulators took steps Tuesday to shut down Land of Lincoln Health, a 3-year-old startup that lost $90 million in 2015 and more than $17 million through May 31. Illinois Department of Insurance officials announced they are seeking a court order allowing the state to take over Land of Lincoln Health and prepare the company for liquidation. The department’s acting director, Anne Melissa Dowling, will work with the federal government to establish a 60-day special enrollment period for Land of Lincoln policyholders to find and purchase new health coverage.

This leaves the count at 16 failures out of 23 Obamacare co-ops. And there will be more. The economics of the co-ops never made sense, dependent as they were on gigantic and unaffordable subsidizes from the government. In fact, none of the economics of any of Obamacare make sense, which is why the whole monstrous law has raised costs for everyone and made being a doctor a far worse bureaucratic nightmare than it was before the law was passed.

It is a good thing the American people have woken up and decided to nominate candidates for President who are avowed conservatives with proven track records for limiting the power of government. Oh wait…

Why no one should be surprised by AG Lynch’s failure to uphold the law

This story, about how Attorney General Loretta Lynch refused during testimony to Congress this week to admit the clear illegality of giving classified information to people without clearance, should not surprise anyone. Nor should her partisan willingness to protect Democratic politicians like Hillary Clinton.

Before she was even ratified by the Republican-led Senate in 2015, she was exposed as someone who was easily willing to ignore the law during her nomination hearings. As I wrote then,

The video of Lynch’s non-answer to Cruz’s question is quite shocking. I dare you to watch it and tell me afterward that this administration and Democratic Party is not a threat to your freedom and rights.

Cruz was not afraid to buck the trend and vote against her. The majority of the Republicans in Congress however were, as always, wimps, and let the Democrats get her approved. We are paying for this now.

Dormant volcano near Rome reawakens

A volcano near Rome that last erupted 36,000 years ago is now showing signs of re-awakening.

Scientists previously assumed Colli Albani, a 15-kilometer (9-mile) semicircle of hills outside Rome, was an extinct volcano since there was no record of it having erupted in human history. But in recent years, scientists have observed new steam vents, earthquakes and a rise in ground level in the hills and surrounding area. These observations, along with new evidence of past eruptions and satellite data, indicate Colli Albani is starting a new eruptive cycle and could potentially erupt in 1,000 years from now, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union.

Privately built smallsat designed deep space communications

The competition heats up: A partnership between two British space companies, a smallsat manufacturer and a space antenna operator, will team up to build and test a new smallsat communications satellite in lunar orbit.

The SSTL-GES Lunar Pathfinder team are already working on the initial baseline design, with technical assistance from the European Space Agency (ESA). SSTL are designing a series of lunar communication satellites and will be building on their heritage of small satellite platforms in Low Earth orbit and Medium Earth orbit to go beyond Earth’s orbit for the first time. GES are upgrading one of the famous antennas at their Goonhilly site in Cornwall, UK, into a deep space ground asset, which will be the first element in a commercial deep space network. In addition, GES will provide a dedicated mission operations centre situated in Cornwall.

What is interesting about this is that this is a private effort to develop a modern commercial deep space communications network for future planetary missions. It would be competitive with NASA’s Deep Space Network, which presently is the only game in town and is generally made up of upgraded 1960s based technology. This new network would also eventually include a dedicated network of smallsats scattered through the solar system to act as communications relays. This is something that NASA does not provide, depending instead on the communications instruments of the planetary missions themselves.

ESA contract for hypersonic engine research

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.

Rocket Lab gets new launch contract

The competition heats up: Rocket Lab has signed a three launch contract with the smallsat Earth resources satellite company Planet (formerly Planet Labs).

The contract covers three dedicated launches of Dove satellites built by San Francisco-based Planet, formerly known as Planet Labs, on Electron vehicles. The companies did not announce terms of the deal, although Rocket Lab quotes a list price of $4.9 million per Electron launch on its website.

Mike Safyan, director of launch and regulatory affairs for Planet, said in an interview during the International Space Station Research and Development Conference here that the number of satellites that each launch will carry is still being determined, but will likely be between 20 and 25. Each Dove is a three-unit cubesat with a mass of about five kilograms.

If this report as well as previous ones are correct, the first Electron rocket launch will happen before the end of this year.

Toilet failure on U.S. segment of ISS

According to this report, the American-built toilet on the U.S. part of ISS has broken down.

The story has few details, and is based on anonymous sources. Nonetheless, I suspect it is true, as the American toilet has had problems in the past, was originally designed for easy transport up and down from ISS on the space shuttle, and is thus difficult to repair in space.
