NASA selects full crew for first operational Dragon mission

10:23 am

Even though SpaceX’s first demonstration manned mission to ISS has not yet occurred, NASA yesterday announced the selection of the full four person crew for the second flight, set for later this year and intended as the first operational mission to ISS, lasting six months.

This announcement tells us several things, all good. First, it appears NASA has now definitely decided that the demo mission, presently scheduled for mid-May, will be a short-term mission. They had considered making it a six-month mission, but it now appears they have concluded doing so will delay the demo launch too much.

Second, that NASA is solidifying its plans for that operational flight, the second for Dragon, including a tentative launch date later in 2020, is further evidence that they intend to go through with the demo mission in mid-May.

Finally, it appears that NASA has decided that it will not buy more seats on Russian Soyuz capsules, something that they had previously hinted they needed to do because the agency was worried the American capsules would not be ready this year. The article describes the negotiations on-going with the Russians about the use of Dragon, as well as the future use by Americans of Soyuz. NASA wishes to have astronauts from both countries fly on both spacecraft (Starliner too, once operational), but Russia is as yet reluctant to fly its astronauts on Dragon. They want to see that spacecraft complete more missions successfully.

Regardless, future flights of Americans on Soyuz will cost NASA nothing, as the agency wishes to trade the seats on the U.S. capsules one-for-one for the seats on Soyuz. It also means that NASA has decided it doesn’t need to buy Soyuz flights anymore, as it now expects Dragon to become operational this year.

2019 was a boom year for the commercial space industry

10:08 am

Capitalism in space: According to a new industry report, 2019 was one of the strongest in years for the entire commercial space industry.

More than 183,000 workers were employed in the U.S. space workforce at the end of 2019, according to the U.S. Bureau of Labor Statistics. Core employment, those jobs most closely aligned with the space industry and not the larger aerospace industry, rose to 141,520 jobs in 2019. This represents a 4.1% increase from the 135,930 private sector workers in 2018 and marks the third year in a row of increasing employment in this workforce and the highest level since 2012.

Some sectors saw significant gains in employment over the last five years. Together, the workforce supporting manufacturing of space vehicles, space vehicle propulsion units, and other space vehicle parts grew by nearly 20% over the past five years, adding more than 14,000 new employees. Other sectors experienced decline. Broadcast and wireless communications equipment manufacturing employment decreased 9.8% over the past five years, shedding more than 5,000 workers.

The report also noted that the COVID-19 panic will likely cause a major negative impact to the industry in 2020, hurting the smaller companies the most.

SpaceX prepares next Starship prototype; releases Starship user manual

9:58 am

From SpaceX's first user manual for Starship

Capitalism in space: Even as SpaceX has begun preparing its third Starship prototype for new testing, it has also released a first user manual for the rocket, outlining its proposed capabilities and potential uses by customers.

From the first link:

The next round of testing is anticipated to begin this week with cryogenic proof testing. These tests will see the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Prior Starship test vehicles have had their campaigns cut short by failed cryogenic testing, including the last flight vehicle SpaceX rolled to the Boca Chica launch pad, Starship SN1.

If all goes right, they hope to begin short flight tests with this prototype, moving to longer and higher flights with the next.

The user manual [pdf] is mostly a short description of what they hope they will be able to accomplish with Starship. It notes that they will build both a cargo and manned variety, and that both will be available for point-to-point transportation on Earth. It also notes:

Starship has the capability to transport satellites, payloads, crew, and cargo to a variety of orbits and
Earth, Lunar, or Martian landing sites. Potential Starship customers can use this guide as a resource for preliminary payload accommodations information.This is the initial release of the Starship Users Guide and it will be updated frequently in response to customer feedback.

I guarantee that much of what is written and drawn here, such as the illustration above, will change significantly as development proceeds.

Yutu-2 and Chang’e-4 complete 16h lunar day on Moon

9:38 am

China’s Yutu-2 rover and Chang’e-4 lander have now successfully completed their sixteenth lunar day on the far side of the Moon, and have been put into hibernation for the long lunar night.

This means that both spacecraft have now worked longer on the Moon than any previous mission.

The news report, from China’s state-run press, provides only one real piece of information: Yutu-2 has now traveled a total of 424.45 meters (1,393 feet), which means it traveled about 24 meters (79 feet) during this sixteenth lunar day.

Their goal is to reach a different geological area of basalt a little over a mile away, a journey they say will take about a year.

I question that time frame however. Yutu-2 has averaged about 88 feet travel per lunar day. To go a mile at that pace will take about sixty lunar days, which is equivalent to between four and five years. The difference might be because the information at the second link is a bit unclear, and that they hope to begin entering the basalt region much sooner.

We shall just have to wait and see.

Total mortality is DOWN in Europe during Wuhan panic

1:29 pm

According to the latest weekly report of overall mortality in Europe, the number of deaths during the March 18 to 24 time period had dropped, even though that was the exact period when the panic and alarm over the COVID-19 epidemic began to reach its height.

The article at the link also notes that this particular flu season has so far been relatively mild, which corresponds with the U.S. data I posted on March 26.

Both the article and his source speculate with some puzzlement as to why this is the case. Obviously, the panic shutting down our entire economy and society is probably helping. At the same time, this flu season was already clearly going to be a mild one, long before the Wuhan panic took over.

Regardless, what these numbers once again suggest is that the response to COVID-19 has been way out of line and over the top. While our bankrupt press keeps focusing on specific deaths and coronavirus mortality rates, they are failing to note that the overall death rate is not changing, and is possibly even dropping.

A good example are the wild rumors, widely reported, of a gigantic order of burial urns for China, implying that these urns were needed because of millions of extra COVID-19 deaths, not reported by the Chinese authorities. What nobody asks is how many urns are normally ordered each year? I suspect the numbers would be quite similar.

We are not all going to die from the Wuhan virus, though the extreme measures our government is forcing us to take might very well kill us, in other ways. At a minimum, those extreme measures are destroying what was once a free society.

IG report: FBI screwed up on every single FISA warrant application it submitted

12:58 pm

So, why hasn’t Trump fired everybody there? A new inspector general review of 29 FBI FISA warrant applications has found that on every single application looked at, the FBI made numerous errors, often failing entirely in doing the most basic required documentation.

The [inspector general] review released Tuesday suggests that the FBI’s problems are widespread. “As a result of our audit work to date and as described below, we do not have confidence that the FBI has executed its Woods Procedures in compliance with FBI policy,” the [report] said in a memo to FBI Director Christopher Wray.

More information here, including the revelation that the FBI could not even find the files for four of these warrants. The IG suspects they might never have existed.

I repeat: Why has Trump so far not fired the entire upper management at the FBI involved in this work? Every single one of these bums should be out on the street, looking for work (though to be honest, the last place I’d want to see them working is as a stock person in a supermarket. They’d hoard and steal, and everyone else would starve.).

For example, the IG memo was submitted to Wray, who has been a top manager at the agency for years, and was directly involved in issuing most of these FISA warrants. Does anyone really expect him to fix this problem? He’s part of it.

Until Trump begins a real house-cleaning, I have no faith in his claim that he is “draining the swamp.” Instead, I see him as simply doing a little light dusting, just enough to make us peons not notice the thick piles of dirt buried under the rugs and beneath all the cushions and behind the books.

Also, this IG report provides further proof that Congress should not renew the FISA court law, when it comes up for renewal again in about two months. The entire law and all involved with it are corrupt, and routinely have abused the power it gave them.

It ain’t simple keeping a camera functioning properly in orbit around Mars

12:31 pm

ADC settings test on MRO
Click for full image.

In doing my normal exploration through the monthly download of new images from the high resolution camera on Mars Reconnaissance Orbiter (MRO), the last to occur near the end of February, I came across a slew of 49 images, each labeled as an “ADC Settings Test,” each covering a completely different location with no obvious single object of study, almost as if they were taken in a wildly random manner.

The image to the right, cropped and reduced to post here, is a typical example. It shows the mega dunes located near the end of the canyon Chasma Boreale that cuts a giant slash into the Martian north polar ice cap, almost cutting off one third of the icecap.

The black areas are shadows, long because being at the high latitude of 84 degrees the Sun never gets very high in the sky, even though this image was taken just before mid-summer, when the Sun was at its highest.

I was puzzled why these images were being taken, and contacted Ari Espinoza, the media rep for the high resolution camera, to ask if he could put me in touch with a scientist who could provide an explanation. He in turn suggested I contact Shane Byrne of the Lunar and Planetary Lab University of Arizona, who coincidentally I had already spoken with several times before in connection with the annual summer avalanche season at the Martian north pole.

Dr. Byrne first suggested I read this abstract [pdf], written for the 2018 Lunar and Planetary Science conference by the camera’s science team. In it they outline two issues with the camera, one blurred images and the second an increasing number of bad pixels occurring in images over time.

The first problem has since been solved. To preserve battery life — another long term problem that they have to deal with — they had adjusted the orbiter’s orbit slightly to get more sunlight and stopped warming the camera during the night periods. “That had the unfortunate effect of changing the camera’s focus,” explained Byrne. “Since we understand that now, we do warm-ups before taking the images and that fixed the blurring problem.”

The other problem however remains, and these ADC test images are an effort to fix it.

New York: Where politicians consider criminals their base and ordinary citizens their enemy

9:36 am

Like the Democrats running California, the reaction of the Democrats running New York to the Wuhan virus has nicely revealed who they consider their base, and who they consider their enemies:

The first story is one of several from New York. Even as the Democrats in charge have moved to place all citizens under house arrest, they also seem to think releasing criminals from jail (the perfect type of quarantine) is a good idea.

No one should harbor any doubts about where the Democrats loyalties lie. They are not really interested in saving lives. They are interested in stamping a jack boot on the face of every decent person. And they know that if their own efforts to impose martial law fail, they know that releasing a lot of violent criminals surely will help.

Stratolaunch now wants to build a reuseable hypersonic vehicle

8:26 am

Capitalsm in space: Stratolaunch announced today that they are now planning to build a reusable hypersonic test vehicle to launch from their giant Roc airplane.

That vehicle, powered by a liquid-propellant rocket engine, will launch from the company’s aircraft and fly to speeds of Mach 5 to Mach 7 before gliding back to a runway landing. It will also be able to take off on its own from a runway under rocket power.

“The Stratolaunch Talon-A is a flexible, high-speed testbed built for offensive hypersonics, hypersonic defense and hypersonic R&D,” the company said in a fact sheet about the program. That document emphasizes the vehicle’s ability to provide “here-to-fore unobtainable measurement access to the hypersonic flight environment on a recurring basis.”

Forgive me if I remain skeptical. From memory I think this is about the fifth different design or concept for launch from Roc, with the previous proposals differing from this hypersonic test vehicle in that they were all intended to go to orbit. All were the same however in that they were trying to find a design that could be launched from Roc and also make engineering and economic sense. So far none has done so.

This new proposal is clearly aimed at garnering government research dollars. It also probably wants those dollars to pay for Talon-A’s development. In a sane world, the military would tell Stratolaunch to build and prove Talon-A’s capabilities first, before signing on.

When it comes to government spending, however, we however are no longer in a sane world.

In the midst of Mars’ volcano country

12:26 pm

lava channel
Click for full image.

Cool image time! While the rest of the world is entirely focused on panic and disease, I am going to go on with my life. The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on December 26, 2019. I suspected this channel was lava, and when I asked Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Arizona, he confirmed my suspicion.

Yes, that surface appears to be lava–it is part of the Elysium plains, which have many geologically-young lava flows. It’s likely that the channel is a lava channel, and the surrounding plains may be from an earlier stage of the same eruption.

The entire surface of the channel and the surrounding plains appear very fresh, mostly because of their smoothness and lack of many craters. You can also see what looks like a recent impact (the small dark splotch near the left edge about two-thirds from the top).

The fresh and smooth look of Elysium Planitia generally has led scientists to conclude that much of this region is formed from lava flows, some relatively recently. Thus, this particular lava channel is smack dab in the middle of Mars’ volcano country, quite vast and extensive. The context map below illustrates this.
