Getting and Installing Linux – Part 3

UEFI and booting Linux on Win 8.1 & 10 machines

by James Stephens

Unified Extensible Firmware Interface (UEFI) is intended to be a modern alternative to BIOS. Ideally UEFI-(Secure Boot) blocks malware from being loaded when the computer is booted by using digital keys which software must possess in order to be booted onto the computer. UEFI supplants the traditional BIOS and it’s post screen, appreciably shortening boot times but sometimes adding a few more steps to set up a computer to boot into Linux. If necessary UEFI-(Secure Boot) may be disabled to allow access to the BIOS and the booting of non-UEFI complaint operating systems, such as 32 bit Linux or legacy Windows, and set up the computer to boot into Linux as I described in the previous post. But I recommend using UEFI if at all possible.

Smallsat market to exceed $22 billion

The competition heats up: A new report estimates the market for small satellites will exceed $22 billion in the next decade.

According to Euroconsult’s latest report, Prospects for the Small Satellite Market, we are on the cusp of a major revolution for the space sector and overall space ecosystem, as more than 3,600 smallsats are expected to be launched over the next ten years, a significant increase from the previous decade. The total market value of these satellites is anticipated to be $22 billion (manufacture and launch), a 76% increase over that of 2006-2015. This rate of growth is unprecedented for the space sector and will bring about fundamental changes as both new and established industry players attempt to increase their capabilities in order to gain market share.

What I expect is a splitting of the space industry, with unmanned smallsats launched by smaller rockets on one hand and big spaceships and payloads launched by big rockets on the other hand. In both cases, the competition will likely force prices down, so that more customers will find space affordable.

Auction of first published book describing Copernicus’ heliocentric theory

Got some spare cash? On July 13, the auction house Christies in London will be selling a first edition of the first book ever published describing Copernicus’ theory that the Earth orbited the Sun.

De Libris Revolutionum Eruditissimi Viridoctoris came not from Nicolaus Copernicus, but from his only student, Georg Joachim Rheticus, and when published in 1540, provided the momentum needed for Copernicus to finally have his landmark De revolutionibus orbium coelestium published in 1543.

Rheticus (1514-1574) published this first book on the subject based on his studies under Copernicus, all the while imploring his master to finally publish the master work which had been finished for 25 years. Copernicus resisted publishing De revolutionibus orbium coelestium for 30 years due to his fear of the Catholic Church, but when Rheticus published this book in 1540, Copernicus finally gave Rheticus the go ahead to publish the major work for him.

Cubesats to the planets!

Link here. The article is a good detailed overview of the many upcoming planetary missions that are using small and relatively inexpensive cubesats as either part of their mission, or are the mission itself.

This trend also partly explains the number of new rocket companies like Rocket Lab and Firefly Space Systems that are developing small rockets aimed at launching cubesats. These companies have recognized a growing demand, and are trying to serve it. As the article notes,

Lifts are so hard to come by that the first interplanetary CubeSat — NASA’s twin INSPIRE mini-spacecraft, intended to test key technology for future missions — has been waiting for almost two years. “We still have to find a ride,” says Anthony Freeman, who manages the Innovation Foundry at NASA’s Jet Propulsion Laboratory in Pasadena, California.

European experimental space junk removal mission to launch

The competition heats up: A European Space Agency mission to test technologies for removing space junk will launch sometime next year.

Presented at the Royal Society’s summer science exhibition this week, and led by the Surrey Space Centre, the systems included a net, harpoon and drag sail, which scientists have incorporated into a test platform for launch into space. The platform will also carry “artificial junk” in the form of small satellites known as CubeSats.

Once the platform is launched into space, a CubeSat will be released. “The CubeSat will be ejected from the platform and then we’ll fire the net at it,” said Forshaw. The CubeSat, hopefully encased in the net, will then fall back towards Earth and burn up. In the case of the harpoon, the researchers have attached a target made of spacecraft material to a carbon-fibre boom that extends from the platform. “When the harpoon impacts it, it is actually going to simulate a real spacecraft being hit,” said Forshaw.

At the end of the mission the third system, a drag sail will be deployed. Attached to the platform, the sail will speed up its return to Earth where it will burn up in the atmosphere. Similar systems have been proposed for future satellites to allow them to be disposed of without leaving space junk.

With the Chinese, NASA, and private companies all developing robotic missions to either clean up space junk or repair satellites, the competition to do this work is going to get very intense in the next decade.

Microsoft gives people another reason to dump Windows

Why I use Linux: In its effort to convince users of earlier versions of Windows to upgrade to Windows 10, Microsoft is now inserting a full screen pop-up upgrade notification, often at decidedly unwanted moments.

The Redmond software giant confirmed today it will start showing dark blue screens urging people to install the latest version of Windows. The full-screen ads will pop up on Windows 7 and 8.1 desktops from now until July 30, when the free upgrade period ends.

China’s space plans for the rest of 2016

The competition heats up: If all goes as planned, 2016 could be China’s busiest year ever in space, and could set the stage for making it a major player for years to come.

They will not only launch their next space station test module, they will introduce a new rocket capable of putting about 25 tons into orbit, making it one of the most powerful rockets available. In addition, they are moving forward aggressively on planetary missions to Mars and the Moon, and on the followup larger space station designed to teach them how to transport people between the planets.

While the US is still substantively far ahead in space, the optics can suggest otherwise.

First, China will be launching people into space, which the US have not had the capability to do since the shuttles were retired in 2011, relying on Russia to get its astronauts to the ISS. Next, the International Space Station is currently only funded to 2024, which means the [Chinese space station], expected to be completed around 2022, could be the only game in orbit. Another issue is that it is becoming increasingly apparent that China is developing technologies and techniques necessary to take its taikonauts to the Moon, and ESA and Russia also have that destination in mind.

As the article notes, the private sector is the U.S.’s trump card (no pun intended).

Sierra Nevada signs deal with UN

The competition heats up: Sierra Nevada has signed a memorandum of understanding with the United Nations, creating the framework for UN member nations to use its Dream Chaser cargo vehicle for science research.

Under the agreement, [Sierra Nevada] committed to dedicating one or more Dream Chaser missions that will host payloads from member countries. The cooperation will focus on developing an interface control document and payload hosting guide to allow payloads developed by participating countries, especially non-space-faring ones, to be flown into orbit.

What this means is that American space technology, developed and owned privately rather than built by NASA, is beginning to grab business wherever it can find it. These UN space missions eventually flown on Dream Chaser might be foreign built, but it will be the American spacecraft that gets them to space..Sierra Nevada will not only make money doing so, it will position itself financially to develop even better space products that it can sell worldwide. Nor will Sierra Nevada be alone in this. The result will be the increasing prosperity of the American aerospace industry as it gains a larger share in the settlement of the solar system.

Blue Origin breaks ground on rocket factory

The competition heats up: Blue Origin has broken ground on a Florida factory for building its orbital rockets.

At 750,000 square feet, the new custom-built facility is designed to be large enough to accommodate manufacturing, processing, integration, and testing of orbital rockets. To put that size in perspective, SpaceX’s rocket facility in Hawthorne, California is nearly one million square feet. Bezos stated that the entire rocket would be manufactured in this facility with the exception of the rocket engines themselves.

What this means is that Bezos is satisfied with the results of the test flights of his suborbital New Shepard spacecraft, and is now ready to upscale to a orbital rocket that would compete with SpaceX and everyone else in the increasingly competitive launch market.

Russia looks to develop reusable first stage

The competition heats up: Russia’s space agency Roscosmos has reactivated the design team for developing a reusable first stage with wings that would return to a runway like an airplane.

They have put in charge of the project the designer of Buran, their Soviet-era space shuttle, and are trying to reassemble his team for this work.

With Russia, proposals like this should only be taken seriously when they actually start test flights.Too often the Russian government,.like NASA here, announces big plans, but fails to figure out how to build anything at a cost anyone can afford.

Geologists discover giant field of underground helium in Tanzania

Geologists have discovered a gigantic new field of underground helium gas, located in Tanzania’s Rift Valley.

Researchers figure there’s about 54 billion cubic feet of helium in just one section of the valley. To put that in context, the Federal Helium Reserve in Texas, which supplies more than 40% of domestic helium needs and contains about 30% of the world’s total helium supply, right now holds about 24.2 billion cubic feet, per Live Science.

The discovery is also important in that it wasn’t an accident. The geologists located the helium based on their theories of where they should find it.

NASA approves robot satellite refueling mission

The competition heats up: NASA has approved plans to launch Restore-L, a robot mission in 2020 to refuel a satellite.

In May, NASA officially moved forward with plans to execute the ambitious, technology-rich Restore-L mission, an endeavor to launch a robotic spacecraft in 2020 to refuel a live satellite. The mission – the first of its kind in low-Earth orbit – will demonstrate that a carefully curated suite of satellite-servicing technologies are fully operational. The current candidate client for this venture is Landsat 7, a government-owned satellite in low-Earth orbit.

This mission is being spear-headed by the division at the Goddard Space Flight Center that ran the repair missions to the Hubble Space Telescope, as well as the recent robotic refueling demonstrations on ISS. With the success of those demonstrations, NASA has obviously decided to move forward with an actual flight.

A Russian space station spun off from ISS?

The competition heats up: Energia, Russia’s main contractor for building its part of ISS, has proposed a plan to separate the Russian modules from ISS, once they are finally launched, to create a new and solely Russian space station.

According to RKK Energia, the prime Russian contractor on the ISS, the new outpost would begin with the separation of the Nauka [Russia’s ISS science module, long delayed] from the rest of the old station in mid-2020s. By that time, Nauka should have two even newer modules in tow. One would be the so-called Node Module, a tinker-toy-like component that could connect to six other modules, crew ships, cargo tankers, structural elements, you name it. The Node Module is already in RKK Energia’s garage and ready to go within a few months after the Nauka.

Next would be the new Science and Power Module (NEM) which, as it name implies, will finally give cosmonauts a state-of-the-art science lab and a pair of large solar arrays, making the Russian segment fully independent from the rest of the ISS in terms of power, communications, and other resources. The launch of NEM, currently promised as early as 2019, would set the stage for these three components to leave the ISS to form ROS.

Russia has always given itself the option to do this, designing its part of the station in a way that would allow it to stand alone.

Virgin Galactic gets another launch contract

The competition heats up: Virgin Galactic has signed a launch contract with new communications satellite company Sky and Space Global to use LauncherOne to put 200 nanosats into orbit in 2018.

This contract suggests that Virgin Galactic might be making good progress on LauncherOne. Or it might mean that Sky and Space has some commitments that forced it to pick Virgin Galactic over other smallsat launch companies that appear to be farther along in development. Either way, the stock market looked at this deal and, as noted in the article above, sold off enough Sky and Space stock for its value to drop.

China launches first Long March 7 rocket, recovers test capsule

The competition heats up: China successfully launched its first Long March 7 rocket on Saturday, the first launch also from its new Wencheng Spaceport.

According to this official Chinese report, the test capsule on the rocket also landed successfully and has been recovered.

Previously I had mistakenly reported that this launch would put into orbit China’s next test space station module. That launch is not until the fall.

Russia looks to reduce Proton launch costs

The competition heats up: Russian officials are considering developing a new variant of the Proton rocket that would cost less to launch and thus make the rocket more desirable in the increasingly competitive launch market.

They have not made a decision yet. As the article notes,

[G]iven the extended length of time required for even less radical upgrades of Proton and the official Russian strategy to phase out the vehicle in favor of Angara-5, it is unclear whether it would be possible to justify the Proton-Light development effort. A number of previous proposals to change the shape and size of the Proton-M rocket were deemed too expensive more than a decade earlier in the rocket’s operational career.

SpaceX’s first stage teaches them how to land on Mars

The competition heats up: This update on the status of SpaceX’s manned Dragon capsule also provides this interesting detail about the engineering knowledge gained from the company’s effort to vertically land its Falcon 9 first stages:

The company is also using the propulsive landings as a way to practically and physically test landing systems in a near-Mars atmospheric environment. “Earth’s upper atmosphere is also a really good analogue for Mars’ atmosphere,” noted [Garrett Reisman, Director of Space Operations]. “When you get up high enough, the density and consistency of the atmosphere is very similar to what you face during Entry, Descent, and Landing (EDL) on Mars. So every time we land, we take one of these rockets and we perform hypersonic retrograde propulsion, the data from which we’re sharing with JPL because it’s the first time this has ever been demonstrated on a major scale.”

To this end, Reisman pointed out that the Falcon 9 first stage landings are really serving as test beds for the EDL systems of eventual Mars missions. “Every time you see one of those rockets coming back, not only is it enabling a whole new paradigm for launching things into space, but it’s also bringing us one step closer to Mars.

As for Dragon, it now appears the company wants to do a full unmanned demo flight to and from ISS before it performs its launch abort test. They will then follow this with a manned demo mission to ISS. All three flights are planned for 2017.

Sierra Nevada prepares for Dream Chaser glide tests

The competition heats up: Sierra Nevada now expects to deliver its refurbished engineering test prototype of Dream Chaser to NASA for new glide tests in August.

“Our version of the shuttle Enterprise is about to be finished for its next phase of flight tests,” [said Mark Sirangelo, corporate vice president.] “Somewhere in the August time frame, it’s going to be shipped off to California, to the Armstrong [Flight Research] Center and to Edwards to be in Phase 2 of flight testing, which is going to be really fun and exciting.”

Sirangelo said lessons learned from the atmospheric flight tests will be applied to the development of the orbital test vehicle, which is now being outfitted in Colorado. That test vehicle, in turn, will blaze the trail for the spacecraft that will carry cargo for NASA under the CRS-2 contract. “We are looking to be launching on time, which is about three years from now, in the second half of 2019,” Sirangelo said.

They get this cargo version flying successfully, and they will certainly get a contract to build a manned version.

Russia in perspective

The coming dark age: This column today attempts to put the present economic shape of Russia into context with the rest of the world. Russia does not come off well.

According to the International Monetary Fund’s most recent data, the Russian economy is approximately the same size as Australia and slightly smaller than South Korea. As an exporter, it is now less important than Belgium, Mexico, and Singapore. And it is poor. The World Bank ranks Russia’s GDP per capita below Lithuania, Equatorial Guinea, and Kazakhstan. A larger proportion of its population lives below the poverty rate than in Indonesia, India, or Sri Lanka. It is ranked 67th in the world in the Global Competitive Index and 66th in the UN’s Human Development Index.

I find this news very disturbing and worrisome. As much as I might consider Russia a competitor to the U.S., I also want it as a nation to thrive, because otherwise it can only be a threat to the rest of the world. If Russia can’t figure out how to be a successful, competitive, and vigorous first world capitalist nation, it can only become something none of us will like. These are the same circumstances that made the rise of Hitler and Mussolini possible.

Unfortunately, I am not optimistic about Russia’s ability to turn things around. When they had the chance after the fall of the Soviet Union, instead of encouraging free competition, the people who remained in power divided the country and its industries up like Prohibition-era gangsters, and stamped out anyone who tried to move in on their territories with new ideas. Those people remain in power, and have acted to further consolidate their power by recreating the Soviet model of centralized control from the top-down.

Russia plans 12 person lunar base by 2030

The competition heats up? Russia has announced plans to build a 12-person lunar base by 2030.

Color me skeptical. Since the late 1990s I have been reading these stories about ambitious Russian space plans, none of which has ever happened. In fact, they all remind me of the dozens of ambitious space plans announced by NASA over the years, none of which ever happened either. Typical of big government projects, they end up on the scrapeheap because government can’t do things quickly or efficiently.
