Blue Origin opens rocket engine factory

Capitalism in space: Blue Origin yesterday cut the ribbon on its main rocket engine factory in Huntsville, Alabama, while also announcing that production of their BE-4 engine for both ULA’s new Vulcan rocket and their own New Glenn rocket will begin in a few months.

In the meantime, made-in-Kent engines are being tested at Blue Originโ€™s West Texas site. Smith said two flight readiness engines will be delivered in May to United Launch Alliance. Theyโ€™ll be used for integrated tests of ULAโ€™s Vulcan first-stage booster, which is taking shape not far from Huntsville in Decatur, Ala.

This is excellent news. For the past year and a half the company has released little information about their progress with the BE-4 engine, suggesting that they might be experiencing issues. Yesterday’s news bursts that pessimistic balloon, indicating that both the Vulcan and New Glenn rockets will be flying, maybe as soon as next year.

SpaceX launches 60 more Starlink satellites; 1st stage landing fails

Capitalism in space: SpaceX this morning successfully launched sixty more Starlink satellites, raising the number in the constellation to 300.

However, though the launch was successful, the first stage, on its fourth flight, failed to land successfully on the drone ship in the Atlantic. Watching the live stream, it appeared from a whiff of smoke on the edge of the screen that the booster missed the target by only a short distance. This is the first time this has happened since 2015 2018 (correction from reader).

That this first stage landing failure is the news story illustrates how far they have come..

The standings in the 2020 launch race:

3 China
3 SpaceX
1 Arianespace (Europe)
1 Rocket Lab
1 Russia
1 Japan
1 ULA
1 Northrop Grumman

In the national rankings the U.S. now leads China 6 to 3.

Successful launch today of Cygnus freighter to ISS

Capitalism in space: Northrop Grumman’s Antares rocket today successfully launched it Cygnus unmanned cargo capsule on a supply mission to ISS.

This was Northrop Grumman’s first flight in 2020. The standings in the 2020 launch race:

3 China
2 SpaceX
1 Arianespace (Europe)
1 Rocket Lab
1 Russia
1 Japan
1 ULA
1 Northrop Grumman

The U.S. now leads China 5 to 3 in the national rankings. The U.S. will likely add to that lead with the planned SpaceX launch of another 60 Starlink satellites Monday.

Coronavirus update

This article about the coronavirus epidemic (the virus is now officially dubbed Covid-19) focuses initially on how the Chinese are even quarantining bank notes in their effort to stem the disease’s spread.

I instead found this quote farther down the page much more significant:

More than 1,380 people with the virus are now confirmed to have died and more than 64,400 have been infected in at least 28 countries and regions.

The death rate of the disease, even as it has grown, remains about 2%. While tragic, this number suggests this hardly has the makings so far of a worldwide catastrophe. If anything, it appears to be about as deadly as the flu, which isn’t something to take lightly but also does not warrant any need for panic or desperation. The flu in the 2017-2018 season in the U.S. infected an estimated 45 million, killing about 61,000, a far lower death rate but impacting far more people. Like the flu, Covid-19 appears to be more deadly to older patients.

This epidemic needs to be taken seriously, but it so far does not justify any panic.

Rocket Lab gets launch contract for lunar cubesat

Capitalism in space: NASA has awarded Rocket Lab the contract to launch the privately-built, for NASA, lunar orbiting cubesat CAPSTONE, designed to test technologies and the orbital mechanics required to build its Gateway lunar space station.

This quote says it all:

The firm-fixed-price launch contract is valued at $9.95 million. In September, NASA awarded a $13.7 million contract to Advanced Space of Boulder, Colorado, to develop and operate the CubeSat.

Using two different private companies, one to build the satellite and the other to launch it, NASA will get a lunar orbiter for just over $23 million. That total equals the rounding error for almost all NASA-built projects.

The launch is set for early 2021.

Justice Dept decides to allow McCabe to skip charges

The law is for only the little people, and Republicans: Our corrupt Justice Department decided today not to prosecute former FBI deputy director Andrew McCabe for lying about his leaks to the media.

And what exactly did McCabe do?

As for the case against McCabe, the 2018 inspector generalโ€™s report faulted the former deputy director for leaking information to then-Wall Street Journal reporter Devlin Barrett for an Oct. 30, 2016 story titled โ€œFBI in Internal Feud Over Hillary Clinton Probe.โ€ The story, written just days before the presidential election, focused on the FBI announcing the reopening of the Clinton investigation after finding thousands of her emails on a laptop belonging to former Democratic Rep. Anthony Weiner, who was then married to Clinton aide Huma Abedin.

The Journal’s account of the call said a senior Justice Department official expressed displeasure to McCabe that FBI agents were still looking into the Clinton Foundation, and that McCabe had defended the agent’s authority to pursue the issue. That leak confirmed the existence of the probe, the report said, which then-FBI director James Comey had up to that point refused to do.

The report said that McCabe “lacked candor” in a conversation with Comey when he said he had not authorized the disclosure and didn’t know who had done so. The IG also found that he lacked candor when questioned by FBI agents on multiple occasions since that conversation.

Or to put it another way, when questioned he lied.

McCabe was also central to the entire effort at Justice and the FBI to use false FISA authorizations to spy on the Trump campaign — for the Obama administration and the Clinton campaign — and to also create the Russian collusion hoax and put in prison a number of Trump associates, for actions in some cases far less egregious than what McCabe did.

But then, he’s an ally of the Democrats, so obviously he is immune from any law or prosecution. The law only applies to Republicans and ordinary citizens who oppose Democrats. Support Democrats, and you will automatically earn a “Get-out-of-Jail” card that will never expire.

Soon, those ordinary citizens are going to get very sick and tied of this double standard, especially when these Democrats start to use their unearned power to impose overbearing restrictions on their freedoms. At some point, that citizenry is going to say, “If the law doesn’t apply to you, then it doesn’t apply to me!”

At that point society collapses, and we have chaos and anarchy.

Images reveal changes in Betelgeuse’s shape as it has been dimming

Betelgeuse dimmed
Click for full image.

Using the Very Large Telescope in Chile astronomers have produced before and after images of the red giant Betelgeuse, showing the changes to the star in the past year as it has dimmed by about 36%.

The image to the right, cropped and reduced to post here, was taken in December and shows the star in its dimmed state. Below the fold is a short video that compares this image with a photograph taken in January 2019. The star was then more spherical and evenly bright.

Betelgeuse’s misshaped profile and uneven brightness is not actually a new thing. See for example this 2017 image, where I noted that the bulge on the star’s side suggested “that continuous observations would reveal the outer atmosphere waxing and waning almost like the stuff inside a lava lamp.” The star is a giant gasbag that in the past has frequently been observed with dark patches on its surface and a sense that it is not always spherical. Those changes however have not occurred with such a significant dimming, a full magnitude

In late December I had posted a story noting that the dimming appeared to be expected, caused by the alignment of two different regular fluctuations of brightness, one 5.9 years long and the other 0.5 year long. It was expected that the star would begin brightening again.

Right now astronomers estimate that the low point in these cycles will occur on approximately February 21st. If the star begins to brighten following that date it would confirm that this dimming is just part of its cycles. If not, then it could be that we are in the preliminaries to a supernova event that would probably make Betelgeuse bright enough to be seen during the day.

Engine failure during test for startup rocket engine company

Capitalism in space: The rocket engine startup Rocket Crafters experienced what the company called “an anomaly” during an engine test yesterday, requiring the local fire department to put out brush fires surrounding the test site.

The company is trying to use 3D printing to build its engines, but appears to have had a string of engine failures, none quite so spectacular, during previous tests.

According to an earlier post about Rocket Crafters in 2018, they had hoped to launch a rocket in 2020. It does not appear they will. Moreover, they are testing the use of hybrid fuels in a somewhat radical design.

[T]he rocket fuel consisted of plastic tubes made from the same base materials as Legos, measuring two feet long and weighing about five pounds, that were stacked on shelves and safe to touch. Combined with nitrous oxide โ€” commonly known as โ€œlaughing gasโ€ โ€” the small-scale test engine on Monday generated about 200 pounds of thrust firing at half-power.

They are not the first to try hybrids and have issues. Virgin Galactic has tried it to, and suffered probably a decade delay in development and a spaceship that does not have as much thrust as they would like.
