Why I won’t use Windows

9:05 am

A remote wildlife project in central Africa has been significantly hampered by the unwanted Windows 10 forced upgrades.

The Chinko Project manages roughly 17,600 square kilometres (6,795 square miles) of rainforest and savannah in the east of the CAR, near the border with South Sudan. Money is tight, and so is internet bandwidth. So the staff was more than a little displeased when one of the donated laptops the team uses began upgrading to Windows 10 automatically, pulling in gigabytes of data over a radio link.

And it’s not just bandwidth bills they have to worry about. “If a forced upgrade happened and crashed our PCs while in the middle of coordinating rangers under fire from armed militarized poachers, blood could literally be on Microsoft’s hands,” said one member of the team. “I just came here recently to act as their pilot but have IT skills as well. The guy who set these PCs up didn’t know how to prevent it, or set a metered connection. I am completely livid.”

As I’ve noted before, I have been using Linux for ten years. Though there have been some areas of annoyance (no software is perfect), I have not found myself limited in what I need to do, in any important matter. If you’ve got a spare older computer that you’re not using right now, install Linux on it and play with it. You will soon find that it does everything a Windows machine does, without the crap.

Luxembourg to invest $200 million in space mining

6:46 am

The competition heats up: The government of Luxembourg has budgeted $200 million to invest in private proposals to mine asteroids for profit.

This government commitment is different than other government space projects in that they are not creating a “space program”, they are literally acting as a venture capitalist, putting their money into private efforts in exchange for profit.

NASA signs Blue Origin for suborbital missions

9:53 am

The competition heats up: NASA has contracted with Blue Origin to use its New Shepard suborbital spacecraft for suborbital research missions.

The company hasn’t actually won any contracts, but is now certified to bid on any of NASA’s suborbital research work, as are Masten Space Systems, Near Space Corporation, UP Aerospace, Virgin Galactic, and World View Enterprise. The difference is that of all these companies, only Blue Origin has a ship built and already flying.

Why the Goldwater Institute sued to block Tucson space deal

9:39 am

Link here.

The fundamental reason is that the Institute believes that, in signing its deal with World View to build its headquarters and launch site in Tucson, Pima County violated several laws as well as Arizona’s constitution. We are supposed to be a nation of laws, and thus government officials should not be allowed to violate those laws, even if they have the best of intentions.

I must say that, though I have no doubt that putting World Views space tourism balloon company in Tucson would be financially good for the city and Arizona, allowing elected officials to break the law to make deals with private companies is a very bad way to do it, and will in the end lead to far worse consequences.

Falcon 9 first stage returns to port, with a noticable list

1:02 am

The competition heats up: The first stage from SpaceX’s most recent Falcon 9 launch returned to port today, showing a visible lean.

Musk said that the stage was probably OK, but there was some risk of tipping. This was due to the fact that the contingency “crush core” was used up. He described on Twitter that the crush core was an aluminum honeycomb for energy absorption in the telescoping actuator. Once the stage was within sight of land, it became clear that the booster had a noticeable lean to it, due to the aforementioned contingency crush core being used up. The ramifications of this are still unclear, but Musk’s tweet implied that the crush core is easily replaceable.

Why I use Linux, part 2

9:20 am

Microsoft has changed its options so that Windows users will no longer be able to refuse an upgrade to Windows 10.

Microsoft’s Windows 10 nagware campaign has entered a new phase, with all options to evade or escape an upgrade finally blocked.

Recently, Microsoft’s policy had been to throw up a dialogue box asking you whether you wanted to install Windows 10. If you clicked the red “X” to close the box – the tried-and-tested way to make dialogue boxes vanish without agreeing to do anything – Microsoft began taking that as permission for the upgrade to go ahead.

Now Microsoft is changing gears. It has eliminated the option to re-schedule a chosen upgrade time once you’ve confirmed it while also removing the red “X” close option from the screen.

The moral dishonesty here is vile, to put it mildly. Microsoft is enforcing these upgrades by offering a series of sneaky bait-and-switch options that are intentionally designed to fool the user into doing something the user doesn’t want to do. And the company is doing this while still claiming that it isn’t forcing anything on anyone.

When you find yourself dealing with a lying snake-oil salesman, you only have yourself to blame if you continue that relationship and get screwed.

Billionaires propose big space plans

9:00 am

At separate interviews given during a media conference held this week in California, Elon Musk and Jeff Bezos each expressed their thoughts about what they hope to accomplish in space over the next few decades.

First, Jeff Bezos outlined his belief that, in order to protect the Earth, humanity is going to have to eventually move its heavy manufacturing off the planet and into space. He thought colonizing the planets was a cool idea, but his focus remained with Earth, and using space as a way to protect it.

Musk meanwhile revealed his company’s long range plans for Mars, including their firm intention to send a Dragon capsule to the red planet during every future launch opportunity, beginning with 2018. Each mission will provide information needed to improve and develop their engineering so that they can hopefully send humans there by 2024.

A realistic appraisal of both men’s proposals will quickly recognize that they are probably overly optimistic. Bezos might be right that we should move our heavy industries into space, but he is not realistic to think this can happen soon, or is even possible. Musk’s company SpaceX might be laying the groundwork for the eventual colonization of Mars, but to think it will begin happening by 2024 is unrealistic.

Still, what both men are proposing are things that they are personally helping to make happen. Neither man has to get anyone else’s permission or approval to push these dreams. All they need to do is make sure the products they are building for accomplishing these tasks can also make money by providing services to others. Since this is exactly what both men are doing, they will likely achieve far more than anyone can imagine, even if the specific proposals they are putting forth now do not happen in their lifetimes.

This bright and very possible future is far different than the powerpoint proposals that NASA and big government have offered to us over and over again for the past four decades. Those ideas, while also ambitious, could never happen because they were dependent on the approval of too many other players, Congress, the public, the press, the bureaucracy. They were not founded on profits, so they became a drain on the economy instead of a source of wealth. The result was that we have gone nowhere and developed little new space technology in the years since the last Apollo landing.

Only now, with our renewed reliance on capitalism and profits, are we finally beginning to see the dreams expressed in those NASA powerpoint proposals coming to life. And it isn’t the government that is making them happen, but free individuals, with big dreams and the will to pursue them.

Expect there to be privately funded manned missions to Mars in the next decade. And expect there to be factories in orbit, far sooner than anyone expects.

Manned Soyuz launch delayed

3:50 pm

More Russian quality control issues? The next manned launch to ISS has been delayed for a week because of an issue with the capsule’s control thrusters.

The article is lacking in any details, though it appears that the Soyuz capsule’s system for controlling its roll is the source of the problem. This issue, on top of the fact that the most recent Soyuz rocket launch last week had an unexplained premature engine shutdown, should make everyone a bit nervous about the reliability and safety of the Russian manned system.

Longest and deepest rail tunnel opens

9:17 am

After 17 years of construction, the world’s longest and deepest rail tunnel has opened today in Switzerland.

If you take into account the two main tubes that comprise the Gotthard Base Tunnel and its various shafts, cross passages and access tunnels, it actually has 152 km (94 mi) of tunnels in total. It is also said to have virtually no gradients.

The initial idea for the tunnel was conceived 68 years ago, but the plans were redrawn on a number of occasions. Once construction finally commenced, there were 2,400 workers on site at peak times. Nine workers also lost their lives during the build.

Airbus Safran begin Ariane 6 engine tests

9:18 pm

The competition heats up: In its effort to build Ariane 6 by 2020, Airbus Safran has begun testing of that rocket’s upper stage Vinci engine.

This test phase, set to last until September, will include running the engine repeatedly as well as for as long as 1,000 seconds. Once they have determined the engine’s design, behavior, and overall thrust, they will be able to design and build the upper stage.

Orbital ATK successfully completes Antares test fire

9:07 pm

The competition heats up: Orbital ATK today successfully completed a 30 second test fire of the first stage of its redesigned Antares rocket, using new Russian rocket engines.

The primary goal of the test was to verify the functionality of the integrated first stage, including new engines, modified Stage 1 core, avionics, thrust vector control and pad fueling systems in an operational environment. During the test, a number of operational milestones were met including full propellant loading sequence, launch countdown and engine ignition and shut down commands, as well as multiple throttle settings including full engine power. The test also validated the launch pad’s operation, including propellant tanking and the use of the water deluge system to protect the pad from damage and for noise suppression.

Orbital ATK will now purge and clean the engines of residual propellants and return the first stage used in this test to the Horizontal Integration Facility for full reconditioning prior to its use on the OA-7 mission slated for later this year. The Orbital ATK team will continue to prepare the Antares rocket that will launch the OA-5 mission, which is in the final stages of integration, systems testing and check-out in preparation for launch this summer.

They hope to launch a Cygnus capsule on Antares around July 6.

Rosetta almost lost during weekend

8:55 am

Because Rosetta’s star tracker became confused by dust particles, the spacecraft lost contact with Earth, went into safe mode, and required the entire weekend for engineers to regain control.

“We lost contact with the spacecraft on Saturday evening for nearly 24 hours,” says Patrick Martin, ESA’s Rosetta mission manager. “Preliminary analysis by our flight dynamics team suggests that the star trackers locked on to a false star – that is, they were confused by comet dust close to the comet, as has been experienced before in the mission.” This led to spacecraft pointing errors, which triggered the safe mode. Unfortunately the star trackers then got hung in a particular sub mode requiring specific action from Earth to recover the spacecraft.

“It was an extremely dramatic weekend,” says Sylvain Lodiot, ESA’s Rosetta spacecraft operations manager.”

The spacecraft has been diving to within only a few miles of the surface of Comet 67P/C-G, which means it is flying close to the comet’s coma. The increased dust in that region has confused the star tracker in the past, but this appears to have been the most serious event yet.

The B-1 Lancer Bomber

6:01 pm

An evening pause: One reason we have a Memorial Day is to honor those who have died to keep us free. We also remember them to remind us that the sacrifice was necessary.

I think it is long past time to repeat the same effort, no matter the cost, and use this plane’s payload a lot more than we are. There are people in the Middle East who are gleefully killing people for the sake of power. We should no longer tolerate them.

Hat tip Rocco.

Premature engine cutoff on Soyuz upper stage

9:20 am

During a successful Soyuz rocket launch of a Russian Glonass GPS satellite last week, it appears that the engine for the rocket’s upper stage cut off prematurely, requiring the third stage to fire longer to get the satellite into its proper orbit.

This scenario is almost identical to what happened with the most recent Atlas 5 launch. There is as yet no word on why it happened, or if the Russians plan to investigate it.

XCOR layoffs, ending Lynx?

8:25 am

In the heat of competition: XCOR has laid off the staff working on its Lynx suborbital spaceplane.

The company has apparently decided to focus on those things that are generating revenues. Lynx was years behind schedule, unfinished with no prospect for profit, as it was only a prototype, not the spaceplane that could be used to fly tourists.

As much as I am not surprised (I have been skeptical of XCOR’s Lynx suborbital project since they announced it in 2008), I am saddened, because I really did want them to succeed.
