The Sun fluctuates far less than other similar stars

A new survey of 369 sun-like stars has confirmed what earlier studies have shown, that the Sun is remarkable inactive compared with similar stars.

A comprehensive catalogue containing the rotation periods of thousands of stars has been available only for the last few years. It is based on measurement data from NASA’s Kepler Space Telescope, which recorded the brightness fluctuations of approximately 150000 main sequence stars (i.e. those that are in the middle of their lifetimes) from 2009 to 2013. The researchers scoured this huge sample and selected those stars that rotate once around their own axis within 20 to 30 days. The Sun needs about 24.5 days for this. The researchers were able to further narrow down this sample by using data from the European Gaia Space Telescope. In the end, 369 stars remained, which also resemble the Sun in other fundamental properties.

The exact analysis of the brightness variations of these stars from 2009 to 2013 reveals a clear picture. While between active and inactive phases solar irradiance fluctuated on average by just 0.07 percent, the other stars showed much larger variation. Their fluctuations were typically about five times as strong. “We were very surprised that most of the Sun-like stars are so much more active than the Sun,” says Dr. Alexander Shapiro of MPS.

It is possible that this inactivity might be because the Sun just happens to be going through a quiet phase, but that is becoming increasingly less likely as the surveys find more and more sun-like stars, and none as inactive as the Sun.

If the Sun is this unusual, we must ask if this inactivity is a fundamental requirement for life to form. Active stars provide a more inhospitable environment. If inactive stars like the Sun are very rare, however, that suggests that life itself in the universe could be very rare as well.

NASA contract award for manned lunar landers rejects SLS

Capitalism in space: NASA today announced the award of contracts to three different private companies to develop manned lunar landers for the 2024 Artemis Moon mission, all of which will not use the SLS rocket to get to the Moon.

The press release described the awards as follows:

  • Blue Origin of Kent, Washington, is developing the Integrated Lander Vehicle (ILV) – a three-stage lander to be launched on its own New Glenn Rocket System and ULA Vulcan launch system.
  • Dynetics (a Leidos company) of Huntsville, Alabama, is developing the Dynetics Human Landing System (DHLS) – a single structure providing the ascent and descent capabilities that will launch on the ULA Vulcan launch system.
  • SpaceX of Hawthorne, California, is developing the Starship – a fully integrated lander that will use the SpaceX Super Heavy rocket.

All, including NASA and the Trump administration, are aiming to get these landers built and launched by the Trump administration’s 2024 deadline.

The first thing that stands out like a beacon is the exclusion of SLS as the rocket to launch any of these landers. Instead, the aim is to use the cheaper privately built rockets of either SpaceX, ULA, or Blue Origin.

The second thing that stands out is the commitment by SpaceX to use its Super Heavy/Starship rocket, not its Falcon Heavy. This means they are directly telling the world that they expect this rocket to be in operation much sooner than most expect. It also suggests that they hope this rocket will supplant SLS as the main rocket to get to the Moon. The award also means that NASA is agreeable to this.

The third thing that stands out is the exclusion of Boeing, which submitted a bid but did not win. Not only does this exclusion reinforce the sense gotten from an earlier report that NASA was very dissatisfied with Boeing and was thus going to rank it very low in future bidding considerations, it also indicates once again that NASA is seriously looking at other options to SLS. Boeing’s rejected bid was apparently the only one linked to SLS, and was rejected.

In fact, that SLS was not mentioned as the rocket for any of these landers strongly indicates that NASA and the Trump administration is finally abandoning SLS as the rocket to get Americans to the Moon.

Which immediately raises the question: Why the hell are we spending any money building it? It no longer has any purpose at all.

Yutu-2 and Chang’e-4 complete 17th lunar day on Moon

According to China’s state-run propaganda news agency, Yutu-2 and Chang’e-4 have successfully completed their 17th lunar day on the far side of the Moon, and have been put into sleep mode for the coming long lunar night.

Yutu-2 apparently traveled another 23 meters (about 75 feet) to the northwest.

Other than that single tidbit, the news report is nothing more than garbage Chinese propaganda, some of which is merely cut and pasted from earlier reports.

New technical problems for SLS?

A new GAO report [pdf] issued yesterday has revealed that SLS engineers are concerned that the rocket’s core stage will develop leaks during its first full test, hopefully scheduled for this year.

[T]he new “Assessments of Major NASA Projects” report released on Wednesday contains what seems to be an entirely new bit of information about the Space Launch System rocket NASA is developing for deep space exploration. The report asserts that engineers at NASA and the SLS rocket’s core-stage contractor, Boeing, are concerned about fuel leaks.

Earlier this year, NASA moved the big rocket’s core stage to a test site at Stennis Space Center in southern Mississippi. Before the COVID-19 pandemic temporarily halted work, NASA and Boeing teams were working toward a critical summer exercise. During this “green run” test, the clamped-down rocket will ignite its engines and burn for about eight minutes to simulate an ascent into orbit.

“Program officials indicated that one of the top remaining technical risks to the green run test is that the core stage may develop leaks when it is filled with fuel,” the report states on page 82. “According to these officials, they have conducted extensive scaled testing of the gaskets and seals used in the core stage; however, it is difficult to precisely predict how this large volume of liquid hydrogen will affect the stage.”

My god, for them to think that the core stage might leak when it is filled with fuel for the first time illustrates the entire bankrupt nature of this entire project. This is why you do tank tests early in the process (as SpaceX has been doing with Starship), so that you don’t get surprised late in the game.

The report also notes further issues with the Orion capsule.

The Orion program plans to reduce the 7-month-long pre-launch processing period by 1.5 months. The program plans to use a mass simulator—instead of the Orion spacecraft—to conduct some prelaunch tests that would otherwise be done after integrating Orion with SLS—providing the program with extra time to complete work before delivering Orion for integration and further testing according to officials. With this shortened process, the program has only 1 week of schedule reserve remaining to the November 2020 launch date, and program officials have said this date will likely be delayed

I must remind everyone that Lockheed Martin got the contract to build Orion in 2005. They have had fifteen years to build this one capsule, and will still deliver it late.

Personally, I hope SLS leaks. If it does, it will force a very long new delay to the program, and very well might finally force Congress and the Trump administration to face reality and cancel it.

Air Force study rubber-stamps Air Force desire to limit launch companies

Garbage in, garbage out: An Air Force commissioned RAND study released yesterday has confirmed the Air Force’s desire to restrict the award of launch contracts for the next decade to only two companies.

“We asked RAND to independently double check the assumptions we used to build our acquisition strategy,” said Col. Robert Bongiovi of the Air Force’s Space and Missile Systems Center in California. “What we found was that our acquisition strategy encompasses RAND’s recommendations as we are already making prudent preparations for a market that will only sustain two providers with our phase two contract structure.”

…Part of the RAND report also recommended that the military closely watch companies over the coming years to see which are the most stable. “The U.S. Space Force should make prudent preparations for a future with only two U.S. providers of NSS-certified heavy lift launch, at least one of which may have little support from the commercial marketplace,” RAND Corporation said of its first main recommendation.

Though the report does suggest that the military continue its development program to help three companies through 2023, it reiterates the military’s belief that there simply isn’t enough business to support more than two companies.

For this reason, the Air Force space division, now the Space Force, had wanted to restrict bidding in the 2020s on its future satellite launches to only two companies out of the four (ULA, SpaceX, Northrop Grumman, Blue Origin) that hope to compete for this business. This report is their attempt to justify that decision.

However, the decision has been repeatedly delayed, partly because of a protest of the plan by Blue Origin and partly because a lot of political pressure in the background from those four companies, none of which want to be excluded from future bidding. It was originally going to be made last year, and is now delayed to later this year.

With the release of the report, the military also suggested that if Congress gives it more money, it might be able to open up bidding to more companies. How typical. Instead of trying to trim costs by allowing competition, the Space Force is now maneuvering elected officials to pump up its budget so that these companies all get more cash while picking the pockets of the taxpayer.

This is the same thinking that caused Boeing and Lockheed Martin to merge their launch operations into ULA and for the Air Force to give that new company a monopoly on launches in 2005. The Air Force assumed then that there wasn’t enough launch business for both companies. Rather than compete to lower costs so that both the Air Force and the private sector could afford more launches, the two companies agreed with this Air Force conclusion and teamed up with the Air Force to form a cartel to control the bulk of the U.S. launch market, while charging the Air Force $200-$500 million per launch.

Then SpaceX comes along and proves them completely wrong. It not only gets more than enough business to make a lot of money (in the billions), it charges only $60 million per launch. When the Air Force tried to deny it the right to bid against ULA for military launches, SpaceX sued, and won.

Now the Space Force wants to do the same thing in the 2020s, limiting to two the number of companies that can bid on contracts. All this will do is raise launch costs, and limit competition.

In the end, I doubt seriously if the Space Force effort here will work. All four companies are developing rockets, and all four should have the right to bid on all future launches. If the military tries to exclude any, they will sue, as SpaceX did, and win. Moreover, the military’s assumption that all four companies cannot survive because it doesn’t have enough business for all four is patently false. SpaceX proved them wrong. All these companies have to do is what SpaceX did, keep their launch costs low enough so that other private customers can buy their services.

There will then be more than enough business to go around, for all.

Small rocket start-ups disqualified by SBA for Wuhan flu relief loans

Capitalism in space: Because of its arcane rules for defining what makes a small company, the Small Business Administration (SBA) has disqualified hundreds of small rocket start-ups from relief loans being issued to help companies whose business has been suspended due to the government-imposed shut downs due to Wuhan flu.

[Space industry groups] claim that hundreds of U.S. startups have been disqualified from loan programs — created under the Coronavirus Aid, Relief, and Economic Security (CARES) Act and the Paycheck Protection Program — because of the way the SBA defines “small business.”

Many startups are funded by venture capital firms that typically invest in a portfolio of companies. To be eligible for the SBA loan program a business has to have fewer than 500 employees. When defining a small business, the SBA applies an “affiliation rule,” requiring companies to include in their worker count all the employees of companies with which they are “affiliated.” That rule requires venture-backed startups to aggregate the employees of all the unrelated companies in which their investors have equity positions, pushing many beyond the 500-employee threshold.

According to the industry groups, 98 percent of U.S. startups have fewer than 100 employees.

In other words, the SBA counts the employees of the venture capital firms as part of the company, when all they are essentially are investors. The start-up itself generally has far less than 100 people employed.

What really has to happen is to shut down the government shut downs. The government has got to get out of the way, and allow freedom to function again. Sadly, I do not see that ever happening, which means that many of these companies will fail, not because they couldn’t get it done but because our fascist new government rulers killed them.

Rocket Lab completes new launchpad at Wallops

Capitalism in space: Rocket Lab has signaled the completion of new launchpad at Wallops Island in the U.S. by the first roll out of an Electron rocket.

The actual launch of a Space Force test satellite is set for sometime in the summer.

Meanwhile, the company is ready to resume launches in New Zealand, but is stymied by the Wuhan panic.

Beck tells the Herald that his company’s Mission Control centre in Auckland is now fully operational with NZ’s move to level 3.

However, its “Don’t Stop Me Now” mission from Launch Complex 1 on the Mahia Peninsula – originally planned for March 24 – is still on hold, with no estimated launch date. “We’re now ready to launch, but currently border restrictions are preventing specialists from entering the country, which is having a negative impact. Our team is on standby to launch as soon as those restrictions are eased,” Beck says.

I hope the company has the resources to weather these government-imposed delays.

Arianespace to resume launches in June

Capitalism in space: Arianespace now plans to resume launches from French Guiana in mid-June with the first Vega launch since that rocket’s first failure in July 2019.

That launch will place 40+ cubesats in orbit. Arianespace hopes to follow with an Ariane 5 launch near the end of July. Of that mission’s three payloads is MEV-2, Northrop Grumman’s second Mission Extension Vehicle to launch, planned to dock with another defunct geosynchronous communications satellite and reactive it for five years.

Ducey extends Arizona shut down two weeks

Fascist: Republican Arizona governor Doug Ducey today announced a two week extension of his so-called “shelter-in-place” order, what is really a house arrest for the general population and a shut down of business that is putting one quarter of the population out of work.

Ducey’s new edicts call for some businesses to begin opening sooner, but with many restrictions. Restaurants however will be locked down until May 12. The edict also said that “no county, city, or town may issue orders, rules, or regulations that conflict with the executive order.”

I wonder if there might be some pushback from local authorities in some areas, as has been seen in other states, especially because of this minor detail:

One in four small businesses in Phoenix could be gone for good, according to the city’s economic director. It could take six years to recover all the jobs that have been lost. “Seeing that 20% to 25% of our small businesses won’t be here when this is over is terrifying for me,” said Christine Mackay, Director of Community and Economic Development for the City of Phoenix.

What does Ducey care if one in four people are out of work? He made himself look good, and now can preen himself as a hero.

To me, he looks like a jackbooted thug. May he roast in hell.

And I dare him to send some police storm troopers to my house to arrest me for saying so.

Perseverance’s helicopter named Ingenuity

After sifting through the 28,000 name suggestions submitted by K through 12 American students for naming the Mars rover Perseverance, NASA has chosen to use a suggestion from an Alabama high school student to name the rover’s prototype test helicopter Ingenuity.

As a technology demonstration, Ingenuity is a high-risk, high-reward experiment. The helicopter will ride to Mars attached to the belly of the Perseverance rover, which is preparing for launch in July or August. For several months following the rover’s landing, Ingenuity will remain encapsulated in a protective cover to shield it from debris during entry, descent and landing. When the timing in the rover mission is right, Ingenuity will be deployed to stand and operate on its own on the surface of the Red Planet. If the 4-pound (2-kilogram), solar-powered craft – a combination of specially designed components and off-the-shelf parts – survives the cold Martian nights during its pre-flight checkout, the team will proceed with testing.

If successful during its 30-Martian-day (31-Earth-day) experimental flight test window, the small craft will prove that powered flight can be achieved at Mars, enabling future Mars missions to better utilize second-generation helicopters to add an aerial dimension to their explorations.

The student, Vaneeza Rupani, had proposed the name for the rover. She instead is honored for the helicopter.

US 1st quarter GDP crashes

Are you enraged yet? Due to the government-imposed shutdowns due to the Wuhan panic, the gross domestic product (GDP) shrank 4.8% in the first quarter of 2020, the most since 2008.

Consumer expenditures, which comprise 67% of total GDP, plunged 7.6% in the quarter as all nonessential stores were closed and the cornerstone of the U.S. economy was taken almost completely out of commission. Durable goods spending tumbled 16.1% while expenditures on services were down 10.2%.

Exports dropped 8.7% while imports fell 15.3%, including a 30% drop in services.

The count of all goods and services produced in the U.S. shows that even though the first quarter saw only two weeks of shutdown, the impact was pronounced and set the stage for a second-quarter picture will be the worst in the post-World War II era.

As the article notes, we ain’t seen nothing yet. And it will only get even worse should our all-wise supreme leaders continue to stretch out this shut down, initially imposed under the big lie that it was merely intended to “flatten the curve” during the epidemic’s onset so that the healthcare system would not be overwhelmed.

It was not overwhelmed. In fact, it never would have been overwhelmed. As I said, it was a big lie.

Now the big lie is that these fascist government lock downs must be maintained in order to prevent the spread of the disease, a goal that is infinitely impossible but if accepted by the public will allow these petty dictators to keep their jackboots on our necks for the rest of time.

ICE & FBI agents took bribes

Agents of both ICE and the FBI took bribes to provide protection as well as cook the records for an indicted Los Angeles lawyer.

We only know this because conviction of the lawyer says so. The FBI agent is named and has been charged. The ICE agent however remains a mystery, for unknown reasons.

But don’t worry. The government is wise and all-knowing. The best thing we can do during this Wuhan panic is give them a lot of power!
