Franky Zapata demonstrating his Flyboard Air

An evening pause: Hat tip t-dub, who wrote that the Flyboard Air “is a real product developed by Franky Zapata. It’s a jet powered board that reminds me of what the Green Goblin used in Spiderman. This video was done in Monaco during the Formula 1 race this year. His company is called Zapata Racing and he has developed a jet pack, water hover board, and those fire hose things people use over water which is a hydraulic Flyboard I believe. If they only had this stuff back in the 70’s when I was growing up.” T-dub also added, “The Flyboard can go up to 10,000 feet, fly at 98 MPH, and has a duration of almost ten minutes depending on use. They have also set a Guinness record with the device.”

My thought: Once again, life imitates art.

Reused Dragon cargo capsule to ISS within a year

The competition heats up: SpaceX hopes to launch a previously flown Dragon capsule to ISS sometime with the next year.

This fall, SpaceX plans to refly one of its landed Falcon 9 rockets for the first time — and a Dragon capsule should make history by launching on a repeat ISS resupply mission shortly thereafter, a NASA official and a SpaceX representative said during a postlaunch news conference Monday. “I think we’re looking at SpaceX-11,” said Joel Montalbano, NASA’s deputy manager of ISS utilization, referring to the 11th resupply mission the company will fly with Dragon and the Falcon 9. (Monday’s launch kicked off SpaceX-9.)

I had been wondering when SpaceX would try to reuse a Dragon, and had assumed the reason it hadn’t happened yet was partly because of NASA reluctance combined with the delays connected with the launch failure last year. Either way, it appears that NASA is now on board and that the company is beginning to gear up for that first reflight.

SpaceX seeks two more pads for returning 1st stages

The competition heats up: SpaceX is asking for permission to establish two more landing pads so that it will have the capability of landing three first stages all within minutes of each other.

“SpaceX expects to fly Falcon Heavy for the first time later this year,” the company said in a statement responding to questions. “We are also seeking regulatory approval to build two additional landing pads at Cape Canaveral Air Force Station. We hope to recover all three Falcon Heavy rockets, though initially we may attempt drone ship landings” at sea.

This news suggests two things: 1. The first Falcon Heavy launch is definitely coming soon. 2. They are going to try to return all three 1st stages during that first launch.

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.

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.

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.
