Labor strikes force Arianespace to suspend all French Guiana launches

3:48 pm

Arianespace today announced that it is suspending all launches from French Guiana indefinitely while it works out the labor problems that surfaced this week with wildcat strikes.

Arianespace chief executive Stephane Israel tweeted Wednesday that officials will set a new target launch date as soon as possible.

The delay will likely cause Arianespace to push back the following launch from French Guiana. Once the Ariane 5 takes off, a Russian-made Soyuz rocket is next in line at the tropical space base, slated to loft the Boeing-built SES 15 communications satellite into orbit to provide in-flight Internet connectivity for airline passengers, and support government, networking and maritime customers across North America. SES 15 also hosts a payload for the FAA’s Wide-Area Augmentation System to enhance airline navigation and safety across the United States.

Liftoff of SES 15 was scheduled for April 4, but it takes nearly two weeks to reconfigure the French Guiana spaceport and downrange tracking stations between launches.

These problems play into the hands of Arianespace’s competitors, SpaceX, the Russians, and ULA.

Vote on Republican Obamacare bill canceled

1:02 pm

The Republican leadership has canceled today’s planned vote on their Obamacare replacement bill, having failed to get the support of that bill from conservatives.

The link is to mainstream news outlet ABC, which typically reports this bill as an effort “to repeal and replace ‘Obamacare.'” This is not a repeal bill. To call it that is to lie about what it is. All it does is tinker a bit with Obamacare, at its outer edges, while cementing the law in place by making the Republican Party now partly responsible for it.

Kudos to the House Freedom Caucus and its conservative members for demanding a full repeal and not backing down. They are right. Pass a full repeal, let the Democrats in the Senate fillabuster its passage. The 2018 elections are now getting closer, and too many of those Democratic senators are vulnerable. Let them campaign on that filibuster. It will do them as much good as it did in 2010, 2014, and 2016.

Another NASA authorization bill this year?

9:20 am

Less than a day after President Trump signed the first NASA authorization bill since 2010, it appears that two major players, one in industry and one in Congress, would like to revisit this bill again this year.

The first story summarizes and quotes from a series of tweets sent out by Elon Musk reacting to the bill, of which the most important noted ““changes almost nothing about what NASA is doing. Existing programs stay in place and there is no added funding for Mars,” and adding, “Perhaps there will be some future bill that makes a difference for Mars, but this is not it.”

The second story describes comments made by Cruz at a Commercial Spaceflight Federation breakfast on March 22, where he noted that in 2017 Cruz hoped to do it all over again, with a different focus: “In this coming Congress, I hope to take up another commercial space launch piece of legislation, and a longer-term NASA authorization.”

I suspect that both want and expect some changes in how NASA has been doing things, and the just-signed authorization did not accomplish that. The bill was written last year, as Cruz also noted in his remarks, and thus could not reflect any policy changes we can expect from Trump. I also suspect that both Musk and Cruz want to influence that policy, which is not yet determined. I am hoping that Capitalism in Space, which their offices have both received, is having some of its own influence here, even if it is tiny.

Deborah Kerr – I whistle a happy tune

6:01 pm

<An evening pause: From the 1956 Rodgers & Hammerstein Hollywood musical, The King and I. The song, actually sung by Marni Nixon, invokes a lesson I have learned works in almost every situation. Act like you belong and have the right to do what you are doing and people will accept this without question. This worked especially well when I was in the movie business.

The song’s lesson is also a good portrayal of the optimism and courage of the American culture in the mid-twentieth century. All good things were possible, if we showed courage and determination.

Hat tip Edward Thelen.

Why U.S. farmers are hacking their John Deere tractors

1:26 pm

Link here.

Tractor hacking is growing increasingly popular because John Deere and other manufacturers have made it impossible to perform “unauthorized” repair on farm equipment, which farmers see as an attack on their sovereignty and quite possibly an existential threat to their livelihood if their tractor breaks at an inopportune time. “When crunch time comes and we break down, chances are we don’t have time to wait for a dealership employee to show up and fix it,” Danny Kluthe, a hog farmer in Nebraska, told his state legislature earlier this month. “Most all the new equipment [requires] a download [to fix].”

The nightmare scenario, and a fear I heard expressed over and over again in talking with farmers, is that John Deere could remotely shut down a tractor and there wouldn’t be anything a farmer could do about it. “What you’ve got is technicians running around here with cracked Ukrainian John Deere software that they bought off the black market”

A license agreement John Deere required farmers to sign in October forbids nearly all repair and modification to farming equipment, and prevents farmers from suing for “crop loss, lost profits, loss of goodwill, loss of use of equipment … arising from the performance or non-performance of any aspect of the software.” The agreement applies to anyone who turns the key or otherwise uses a John Deere tractor with embedded software. It means that only John Deere dealerships and “authorized” repair shops can work on newer tractors.

This behavior by John Deere is no different than the immoral behavior of Microsoft to its customers (which is why I use Linux). It is unacceptable and should encourage the rise of significant competition from other tractor companies.

The longest stretch of no sunspots since 2009

10:45 am

The Sun just completed its longest stretch, 15 days, without sunspots since 2009, suggesting once again that the solar minimum is coming much sooner than expected.

So far this year the Sun has been blank 34% of the time, a pace that makes this year almost as blank as 2009, the year in which the previous solar minimum ended. This suggests that 2017 might be the year in which the next solar minimum begins, which would be about two years earlier than the earliest predictions.

The more likely scenario is that 2018 will be the year the solar minimum begins, with 2019 when solar activity bottoms out. This will still be much earlier than expected, making this solar cycle only about 9-10 years long. What makes this more significant is that historically short cycles always went with high activity, while long cycles signaled an inactive and weak maximum. This cycle will be the first that is both short and weak.

What happens next remains the big question. Will the Sun enter a grand minimum, with no sunspots for decades? Or will sunspot activity continue? Since solar scientists really do not yet understand the mechanism within the sun’s magnetic field that causes this solar cycle, we really can’t answer these questions, in advance. We must wait, and see.

Lawsuit against San Jose by Trump supporters to go forward

9:08 pm

A federal judge has given the go-ahead to a lawsuit by Trump supporters against the city of San Jose for not protecting them from attacks by anti-Trump protesters during a Trump rally in June.

The city police essentially forced Trump supporters into the anti-Trump mob, and then stepped back and did nothing when that mob attacked them. You can see some of the videos of these attacks here.

More wear found on Curiosity’s wheels

6:58 pm

Routine inspections of Curiosity’s wheels has found new damage on the rover’s left middle wheel.

None of this is unexpected. Nor is it a serious problem. They expected the wheels to wear out over time, though I must say that it seems to me that Curiosity’s wheels, in use now for about five years, do not seem to be doing as well as Opportunity’s, working on Mars for more than a dozen years. Opportunity was only supposed to last for 90 days. Curiosity was designed to last years. Yet, it seems that Curiosity’s wheels are wearing out faster than Opportunity’s.
