Behind The Black – Robert Zimmerman

Yutu-2 and Chang’e-5 complete 14th lunar day

February 4, 2020 9:10 am Robert Zimmerman

China’s Yutu-2 rover and Chang’e-5 lander have successfully completed their fourteenth lunar day of operations on the far side of the Moon, and have gone into hibernation.

The report from China’s state-run news agency is, as usual, decidedly uninformative. It is written to make it appear that Yutu-2 traveled 367 meters during this most recent lunar day, when in truth that is the total distance since landing. In comparing this total with the total at the end of the thirteenth lunar day, we find that Yutu-2 actually traveled only ten meters.

The report also provided no other information about where the rover went, or what it has been doing, other than saying the rover and its instruments operated as “planned.” The article did not even include a picture, either new or old.

It is a shame that China operates in this secret way. They are doing good stuff on the Moon. If they touted it proudly to the world, in as much detail as possible, they would do themselves far more good.

How to spot a glacier on Mars

February 3, 2020 3:34 pm Robert Zimmerman

Click for full image.

Overview map

The science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) today posted a nice lesson on what features to look for when you are trying to find glaciers on Mars.

To do this they used one of the earliest images of a Martian glacier, taken by MRO on June 12, 2008. The image to the right, cropped and reduced to post here, shows that entire glacier, coming off a mesa in the chaos terrain region of Protonilus Mensae, a region of mesas and glaciers that I highlighted in an earlier post in December, showing images of a mesa that had numerous glaciers flowing down from all sides.

The overview map to the right shows the location of both that earlier glacier-surrounded mesa (the red dot in Protonilus Mensae) and today’s image (the blue dot).

What the MRO science team has done with the image today however is to use it to illustrate the most important geological features that one will see when looking at a Martian glacier.

Mock and Real Mars habitats on Earth

February 3, 2020 8:49 am Robert Zimmerman

On January 31, 2020 the Mars Society issued a press release touting its newest mock Mars habitat mission to its Mars research station in the high desert of Utah.

During this mission, one crew is operating at MDRS, while a second crew works out of the MAU habitat, which consists of a series of interlocking geometric tents that house crew quarters and a research area. The crew is made up of medical professionals who are testing how two teams on the same planet would collaborate on emergency medical procedures.

Located in southern Utah, MDRS serves as a home base for crews participating in Mars surface simulation testing and training. Depending on the individual crew’s specialization, its scientific focus ranges from geology to engineering, communications to human factors, robotics to microbiology. A wide variety of scientific and engineering research and educational outreach are typically conducted by crews at MDRS.

The newly-arrived MAU participants (designated as Crew 220) have set up their temporary second habitat close to MDRS, with part of the crew staying at the MDRS facility, while an additional crew is housed in the MAU-developed habitat out of sight of the main station. Halfway through the mission, the crews will rotate stations, thereby allowing each team an opportunity to experience both operational habitats.

While this simulated mission will certainly learn a few things about long term isolation by small crews, it does not appear to me to be a very real simulation of living on Mars. While the MDRS facility is quite sophisticated, it isn’t an entirely closed system. Moreover, the environment here, even in winter, does not come close to simulating the Martian environment. It is too warm and it has is a full atmosphere. And it certainly is not isolated. If someone gets seriously ill, or the facility experiences an irreversible failure, immediate evacuation is always an option.

Still, the Mars Society has been using this facility for simulating Mars missions since 2001, and has completed eighteen field seasons involving more than 1,200 participants. I am sure they have accumulated a great deal of useful data that can be applied on future Mars missions.

However, the U.S. has been running a much more realistic Mars simulation habitat since just after the end of World War II, and it appears that few realize it.

The moral and intellectual decline of American academic research

February 2, 2020 10:42 am Robert Zimmerman

Link here. This well documented essay outlines how federal government funding has poisoned American academic research, and if we do nothing to fix it, will only be another precursor of a coming dark age.

My experiences at four research universities and as a National Institutes of Health (NIH) research fellow taught me that the relentless pursuit of taxpayer funding has eliminated curiosity, basic competence, and scientific integrity in many fields.

Yet, more importantly, training in “science” is now tantamount to grant-writing and learning how to obtain funding. Organized skepticism, critical thinking, and methodological rigor, if present at all, are afterthoughts. Thus, our nation’s institutions no longer perform their role as Eisenhower’s fountainhead of free ideas and discovery. Instead, American universities often produce corrupt, incompetent, or scientifically meaningless research that endangers the public, confounds public policy, and diminishes our nation’s preparedness to meet future challenges.

The essay focuses on how the lure of tax dollars has warped and corrupted medical research, but anyone with any knowledge of almost all other fields of science that now depend on federal funding will recognize the same problems.

Many of the stories the author documents include major universities (Duke, Cornell, Harvard) that not only have been producing lots of studies have required retraction or included documented fraud, but have also not done anything to punish those involved.

Overall, this study, along with the many examples of totalitarian attempts to silence dissent on American campuses, proves that these institutions no longer any public funding. At a minimum, high school students should consider other colleges. At best, they should be shut down.

Maxar wins NASA contract to build robot for assembling test large antenna dishes in orbit

February 2, 2020 10:26 am Robert Zimmerman

NASA has awarded the private company Maxar a contract to build a robot that will assemble a test large antenna dish in orbit.

The robot will fly as part of the Restore-L mission, whose primary robotic mission goal will be to refuel Landsat-7, originally launched in 1999.

Al Tadros, Maxar’s vice president of space infrastructure and civil space, said the NASA contract funds SPIDER through completion. It also funds a SPIDER demonstration with Tethers Unlimited’s MakerSat to build a 10-meter boom in space and attach it to Restore-L, he said.

Maxar’s demonstration contract calls for the in-orbit assembly of multiple antenna reflector dishes into one single reflector. Communications satellites use reflectors to beam television channels and internet connectivity to users. Maxar said SPIDER’s demonstration could show how commercial satellites and telescopes could carry fixtures currently too large to fit inside rocket payload fairings.

Restore-L was originally targeted for a 2022 launch, but this new contract implies that it might launch later to include this additional test.

The decision by the Trump administration to go all-in with the use of private space to get things done is bearing fruit. In the past, when NASA insisted that it build everything, it didn’t have the resources to do very much. Now that it is harnessing the skills of many independent companies to build many different things (from launchers to landers to rovers), suddenly more is getting done for less in less time. For example, Restore-L is a NASA built project that has taken more than a decade to reach orbit. NASA has now added a private component that it intends to fly in five years.

Russian satellite rendezvouses with U.S. military satellite

February 2, 2020 10:11 am Robert Zimmerman

A Russian military satellite, dubbed Inspector and supposedly designed to “monitor other [Russian] satellites in orbit”, has rendezvoused with a U.S. military satellite satellite, and is maintain a distance of about 200 miles.

With such a close range, it allows Cosmos 2542 to take numerous photographs of USA 245. “The relative orbit is actually pretty cleverly designed,” Thompson wrote. “Cosmos 2542 can observe one side of the KH-11 when both satellites first come into sunlight, and by the time they enter eclipse, it has migrated to the other side.”

Some news reports have suggested this might be a precursor to an attempt to destroy the U.S. satellite, but that is silly hype. The Russians have apparently decided to use their long ago developed technology for unmanned rendezvous (with Progress freighters to manned space stations) for military surveillance in space. There is nothing illegal about them doing this.

From the U.S. military perspective, this Russian action however once again points out the need to not depend on large big and expensive satellites that are launched rarely and are difficult to replace. They are too vulnerable. Better to put up many small and cheap satellites that are easy to replace and also act to provide redundancy.

Crested Saguaro

January 31, 2020 7:34 pm Robert Zimmerman

Crested saguaro

Today I took the morning off to do a hike with Diane and friend Susan. I did this mostly because other caving-related conservation work on recent and future weekends has made it impossible for me to go hiking with my wife. Since she hikes with Susan on Fridays, I decided to join them.

We went to Tucson Mountain Park, on the west side of Tucson, to do one of the more well known trails. The photo to the right, taken by Diane back in 2016, shows the spectacular crested saguaro she discovered in plain site on that hike but had gone unnoticed by us for years.

Everyone knows saguaros for their classic western look that makes it the state wildflower of Arizona. Normally they have a central post that sometimes has one or more arms extending from it. For normal saguaros the tops of the central post and the arms are almost always symmetrical and rounded.

However, in rare cases (about 1 in 10,000) something strange happens and a saguaro begins to grow wildly at its peak, or even along its entire length. Such freaks are called crested or cristate saguaros, and only about 2,200 have been found throughout the saguaro range in the southwest. When you find one it is always with a sense of triumph and wonder.

We began to look for crested saguaros during hikes around 2015, after a friend had shown us two on a nearby hike that we had done frequently without ever noticing this wonder of nature that was right before our eyes. Thus Diane’s discovery to the right in 2016. Today we went back on that same hike and found it again. It had not changed in any way in the past four years that I could tell when comparing pictures. Regardless, it is one of the wildest crested saguaros I’ve ever seen.

No one really knows why this happens. My theory today, in looking at this one, is that it was on drugs.

A Martian avalanche: before and after

January 31, 2020 6:35 pm Robert Zimmerman

Click for full resolution animation.

Cool image time! The science team for the high resolution camera of Mars Reconnaissance Orbiter (MRO) today released a beautiful blink animation showing the before and after terrain at an avalanche site along the scarp of Mars’s north pole ice cap.

The animation is very cool, but it is also helpful to align the two images next to each other to carefully study what actually changed. The image to the right, cropped and reduced here, shows both photos. (Thank you to planetary scientist Shane Byrne for splitting the animation for me.). I have added the white bars to indicate the cliff section that broke off during the avalanche. That section was made of water ice, with probably some dust and rocks mixed in, and broke into the blocks that are now scattered on the ground below.

This avalanche itself is actually not unusual and as I noted in an earlier post, is part of an annual season of numerous avalanches that occur on this northern scarp of the polar ice cap each spring. As written by Dr. Candice Hansen of the Planetary Science Institute in Tucson, Arizona,

Every spring the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose. When they reach the bottom of the more than 500 meter tall cliff face [about 1,600 feet], the blocks kick up a cloud of dust.

And as Byrne noted to me in an interview when I asked him how it was possible for MRO to image so many avalanches, as they occur,

“It is incredible. I think this is the most incredible thing about the whole process.” said Byrne. “If you fly over a mountain range on the Earth and take a picture, the chances catching an avalanche in progress are almost zero. But on Mars half of the images we take in the right season contain an avalanche. There’s one image that has four avalanches going off simultaneously at different parts of the scarp. There must be hundreds to thousands of these events each day.”

In an email exchange with him today, he also added that this is not the first before and after comparison images obtained. “We’ve been seeing these blockfalls for several years now. That’s partly why these scarps are being so intensively monitored by HiRISE.”

Do these avalanches mean that the Martian northern polar ice cap is shrinking? Maybe, maybe not. Right now scientists think the cap is in a steady state, neither growing or shrinking. These events are thus more likely comparable to the routine calving of ice sections from the foots of glaciers here on Earth, a common tourist destination in the waters of western Alaskan coast.

Strange parallel grooves in Martian crater floor

January 31, 2020 9:30 am Robert Zimmerman

Click for full image.

Cool image time! The image above, cropped to post here, was taken on December 2, 2019 by the high resolution camera of Mars Reconnaissance Orbiter (MRO) of a crater in the northern lowlands of Mars. It focuses in on the strange lineated ruts and ridges found on the crater’s central floor, as indicated by the black box on the wide shot to the right.

The north-south alignment of these groves suggests to me that they are wind caused, as if dust and sand had ponded in the crater’s lowest point and was then shaped by the prevalent winds. They also appear solid and old, as if this shaping occurred a long time ago and they are now decaying with time.

This location is at the same latitude as the plains around Erebus Montes, the prime candidate landing site for SpaceX’s Starship, and a region where a lot of shallow subsurface ice has been detected. It lies due west of that region, separated by the north-south Phlegra Montes mountain chain. At this latitude, 36 degrees north, scientists have found ample evidence of water ice, though some regions have more than others. This crater sits on the edge of this particular rich area, which might explain why the crater looks more solid and dry than others at similar latitudes. There simply might be less ice here, or the ice lies deeper below the surface.

I am off with Diane on a hike this morning, so this cool image fills in for my normal morning news posting. I should catch up this afternoon.

You Use a Cartridge Razor? Dump it!

January 30, 2020 6:01 pm Robert Zimmerman

An evening pause: Recently my cousin Ken Kueny, a former software manager at Orbital ATK and now the owner of Karn Custom Woodwork, a major carpentry company in Virginia, made me aware of a new example in the movement to buy dumb (rejecting modern hi-tech for older technology developed in the 20th century), this time related to shaving utensils. Apparently, men appear to be abandoning the modern expensive cartridge multi-blade razors for old-fashioned safety razors and double-edged blades.

I, who hate shaving and have a beard partly so that I only have to do a trimming about twice a week, was astonished. The video below gives a quick lesson on how to shave with a safety razor, for those too young to remember these tools. It also gives a sense of why it is better to do it this way. This video shows just a sampling of the many different types of available safety razors, and the engineering differences for each. Do a search on youtube and you will see numerous similar videos touting the advantages of going retro when shaving. All are quite convincing.

This new trend won’t make me shave my beard, as I also like it very much, but it does illustrate once again that while new designs can certainly improve things, newer is not always better.

Update on coronavirus spread

January 30, 2020 1:08 pm Robert Zimmerman

Link here. As expected, the situation in China continues to be serious and somewhat out of control. The key data point however is this:

The number of confirmed infections across China has risen to 7,711, resulting in 170 deaths. By comparison, there were 5,327 cases of severe acute respiratory syndrome (SARS) in China during the 2002-2003 outbreak, although that virus was more deadly, claiming 349 lives.

In about a week the number of those infected has grown exponentially, far far faster than the previous SARS epidemic. In one week it just about passed SARS, which took a year to accumulate the same numbers.

At the same time, coronavirus still appears relatively mild, having produced half the deaths, about 2% of all those infected. This number however can easily rise, as the disease is still in its early stages for the majority of those infected.

So far the detected cases outside of China remain small, but they are also on the rise, including the first detected human-to-human transmission entirely within the U.S.

Once again, it is essential that no one panic over this virus. Its potential danger should also not be poo-pooed. Until we know more, it poses a threat that must be faced.

Honoring Churchill on anniversary of his funeral

January 30, 2020 12:16 pm Robert Zimmerman

On this date in 1965 the United Kingdom buried Winston Churchill in the first state funeral for a non-royal family member in thirty years, and one that lasted four days.

Below is a short video of that event, possibly the largest such funeral in the twentieth century. And it was so large for good reason, as noted by then Australian prime minister Sir Robert Menzies:

In the whole of recorded history this [the Second World War] was, I believe, the one occasion when one man, with one soaring imagination, with one fire burning in him, and with one unrivalled capacity for conveying it to others, won a crucial victory not only for the Forces (for there were many heroes in those days) but for the spirit of human freedom. And so, on this day, we thank him, and we thank God for him.

I wonder, who are our Churchills today? Who is willing to stand against tyranny, either within or without our country, and fight for freedom?

More Martian pimples

January 30, 2020 12:01 pm Robert Zimmerman

Click for full image.

In a captioned image release last week from the science team of the high resolution camera on Mars Reconnaissance Orbiter (MRO), planetary scientist Alfred McEwen describes a string of mounds aligned and deformed by a fissue.

The image, cropped and reduced to post here, is to the right. As McEwen notes,

A possible geologic interpretation is that as the rift began to open, subsurface material (perhaps mud) erupted to create the mounds, which were then deformed as the rift continued to spread.

Located in Chryse Planitia, the region of the northern lowland plains just north of the outlet from Valles Marineris, these mounds and their probable geological origin seem very similar to the pimple mounds I highlighted in a cool image only last week. The only difference is that the earlier posted pimples were not aligned with any obvious fissure or rift.

Why Bigelow passed on NASA bid for new ISS module

January 30, 2020 9:43 am Robert Zimmerman

Capitalism in space: In an interview this week, Robert Bigelow provided his reasons for not bidding on the NASA agreement to build additional modules for ISS, won by passed on NASA bid for new ISS module, won by Axiom this week.

In a Jan. 28 interview, Robert Bigelow said his company decided not to bid on a NASA competition for access to an ISS docking port for a commercial module because the funding NASA offered for doing so was too low. NASA announced Jan. 27 it selected Axiom Space to use the port through its Next Space Technologies for Exploration Partnerships (NextSTEP) program.

When NASA issued the request for proposal in June for the docking port, NASA said it projected making $561 million available for both the docking port solicitation and a separate one to support development of a free-flying commercial facility. “That was asking just too much” of the company, Bigelow said. “So we told NASA we had to bow out.”

NASA now appears willing to separate the free flyer from the program, meaning that it wishes to make more money available to both, something Bigelow says is necessary because at the moment he believes there are not enough customers outside NASA for any orbital space business to make a profit.

On this last point I think Bigelow might be wrong. I also think it will be a mistake for NASA to provide these companies too much money. Keep them on a tight lease, force them to work efficiently so that they lower costs. This will make it easier for them to charge less to outside customers, thus widening their customer base more quickly.

If NASA gives them a blank check, it will remain the only customer, as the companies will then end up spending too much building their facilities, making it impossible for any other private customer to afford using it.

Boeing budgets for extra unmanned Starliner test

January 30, 2020 9:30 am Robert Zimmerman

Capitalism in space: Boeing has put aside $410 million in its next budget to pay for a possible second unmanned Starliner test, just in case NASA demands it.

The company said in its fourth quarter earnings release Jan. 29 that it was taking the charge “primarily to provision for an additional uncrewed mission for the Commercial Crew program, performance and mix.” It noted that NASA was still reviewing data from the Orbital Flight Test (OFT) mission in December that was cut short, without a docking at the International Space Station, by a timer problem.

“NASA is in the process of reviewing the data from our December 2019 mission,” Greg Smith, chief financial officer at Boeing, said in an earnings call. “NASA’s approval is required to proceed with a flight test with astronauts on board. Given this obligation, we are provisioned for another uncrewed mission.” Neither he nor Boeing’s new chief executive, David Calhoun, elaborated on that during the call, which was devoted primarily to issues related to the company’s 737 MAX airliner.

It might be too early to say, but my instincts are telling me that this decision, made very quickly, is a very good sign for Boeing. It suggests that Calhoun doesn’t fool around, that he takes very seriously the need for Boeing to serve its customers. In the past Boeing would have lobbied NASA, its customer, to pay for a possible additional flight (something NASA is not required to do according to the contract). Now Boeing instead makes it clear that it has accepted the responsibility of that additional flight, right off the bat, something that any good and healthy company should do.

Parker completes fourth solar flyby; sets new record

January 30, 2020 9:19 am Robert Zimmerman

The Parker Solar Probe yesterday completed its fourth orbital close fly-by of the Sun, setting a new speed record.

The spacecraft traveled 11.6 million miles from the Sun’s surface at perihelion, reaching a speed of 244,225 miles per hour. These achievements topple Parker Solar Probe’s own previous records for closest spacecraft to the Sun — previously about 15 million miles from the Sun’s surface — and fastest human-made object, before roughly 213,200 miles per hour.

Parker will continue to break these records with each orbit.

Trump’s Mideast peace plan: What it really reveals

January 29, 2020 11:57 pm Robert Zimmerman

This week President Trump unveiled his proposed comprehensive peace plan for settling the differences between the Palestinians and the Israelis. The plan has not garnered a lot of press attention, partly because of the media’s general bias against Trump, but mostly because no one expects it to be adopted. The plan is crucially important, however, not because it might become reality but because of what it reveals about the various players involved, telling us everything we need to know about them as well as what they really stand for.

The details of that plan, discussed here at great length, suggest that it offers a mixed bag to both sides. While it will give billions in aid to the Palestinians to help jump start their own sovereign state, carved out of the territories they presently hold, it also recognizes Israel’s hold on the parts of the West Bank it presently occupies.

It also demands the following from the Palestinians:

Before Palestine can unlock any benefit, the Hamas government in Gaza must be removed from power and replaced with the Palestinian Authority. If Hamas wants to remain in power, the group must renounce violence, fully disarm, and accept the existence of the State of Israel as the nation state of the Jewish people. That’s a non-starter. Hamas faces political and economic pressure, but a capitulation of its ideology or its power is unlikely. The plan also requires the new State of Palestine to safeguard freedom of speech and religion and promote financial and government transparency. [emphasis mine]

The responses to this plan are, as I said, quite revealing.

Two defunct satellites barely miss each other

January 29, 2020 9:42 pm Robert Zimmerman

Missed it by that much: According to the US Space Command, two defunct satellites, one the first infrared space telescope ever launched and the other a military technology test satellite, apparently did not collide tonight, barely missing each other.

Prior to impact it was estimated they could get within as little as 40 feet. Since the military satellite had booms 60 feet long, the possibility of impact was quite real, especially because there was also a margin of error in the calculations and the two satellites were traveling almost 33,000 mph relative to each other. Had they hit each other the cloud of debris would have caused enormous problems, as the pieces would have been a threat to many other satellites presently in orbit.

Fortunately they missed each other. The problem of many such defunct satellites and upper stages and general space junk still exists however. Someone could make some good money providing a service to clean this stuff up. I suspect governments would be willing to pay to have it done.

GAO warns of more Webb delays

January 29, 2020 8:47 am Robert Zimmerman

The race to the bottom between Webb and SLS continues! A new Government Accountability Office (GAO) report warns that there is high likelihood that NASA will not meet its March 2021 target launch date for the James Webb Space Telescope.

The report noted that the program performed an updated joint confidence level analysis of the mission’s cost in schedule in October. “Because of schedule delays resulting from technical challenges coupled with remaining risks faced by the project, the analysis assessed only a 12 percent confidence level for the project’s ability to meet the March 2021 launch readiness date,” the report stated.

NASA missions usually set cost and schedule estimates at the 70% confidence level. Using that metric, the launch would likely take place in July 2021, a delay of four months, according to the report.

Webb is now more than a decade behind schedule, with its budget ballooning from $1 billion to just under $10 billion. These facts essentially wiped out almost all new astronomical projects in the 2010s.

Voyager 2 in safe mode

January 29, 2020 8:41 am Robert Zimmerman

After forty years of operation and successfully leaving the solar system, Voyager 2 has experienced a technical issue that caused it to go into safe mode.

According to NASA, Voyager 2 failed to perform a scheduled maneuver on Saturday January 25. The craft was due to rotate a full 360 degrees to calibrate its magnetic field instrument, but for some reason the action was delayed. That in turn meant that two particularly power-hungry systems were left running at the same time, which overdrew the available power supply.

…As of January 28, the team managed to turn off one of those high-power systems, allowing some scientific instruments to be switched back on. Engineers are currently analyzing data to figure out the status of the rest of the systems, to work out how to turn off the second one and return the craft to normal operations.
