Test cubesat to launch to Gateway lunar orbit
NASA has awarded a $13.7 million contract to Advanced Systems to build a cubesat to test placement and operation in the orbit the agency wishes to place its Lunar Gateway space station.
The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) is expected to be the first spacecraft to operate in a near rectilinear halo orbit around the Moon. In this unique orbit, the CubeSat will rotate together with the Moon as it orbits Earth and will pass as close as 1,000 miles and as far as 43,500 miles from the lunar surface.
The pathfinder mission represents a rapid lunar flight demonstration and could launch as early as December 2020. CAPSTONE will demonstrate how to enter into and operate in this orbit as well as test a new navigation capability. This information will help reduce logistical uncertainty for Gateway, as NASA and international partners work to ensure astronauts have safe access to the Moon’s surface. It will also provide a platform for science and technology demonstrations.
While proving the capability of cubesats for these unmanned planetary probes is all to the good, I must once again point out that making this orbit a way station on the way to the Moon actually makes it more difficult to get there. More fuel and equipment is required to transfer to the Moon once you are in Gateway’s planned orbit.
Based on our past experience with NASA boondoggles like this, Gateway will therefore act as a drag on future American lunar exploration. While other nations (China, India) will be landing on the surface, we will repeatedly find that our surface missions are delayed because of the added complexity of going from Earth to Gateway and then to the surface.

First high quality image of interstellar comet
Click for full image.
The Gemini Observatory on Mauna Kea has successfully taken the first high resolution image of comet C_2019 Q4, unofficially Comet Borisov (after its discoverer), the first interstellar comet ever discovered.
The image to right, cropped to post here, is that image. It clearly shows the growth of a coma and possible tail, indicating that as it is approaching the Sun it is releasing material from its surface.
Right now the comet is visually very close to the Sun, when looked at from the Earth, making observations difficult. As in the next few months it drops towards its closest approach of the Sun, and the Earth circles around in its own orbit, the viewing angle will improve.

LRO to image Vikram landing site next week
The Lunar Reconnaissance Orbiter (LRO) science team plans to take high resolution images of the Vikram landing site when the orbiter flies over that site on September 17, thus allowing them to release before and after images.
Noah Petro, LRO’s project scientist at NASA’s Goddard Space Flight Center, said that the orbiter is due to fly over the Vikram landing site Tuesday, Sept. 17. “Per NASA policy, all LRO data are publicly available,” Petro wrote in an email. “NASA will share any before and after flyover imagery of the area around the targeted Chandrayaan 2 Vikram lander landing site to support analysis by the Indian Space Research Organization.”
Officials with India’s space agency ISRO have said they have photographed Vikram with their orbiter, Chandrayaan-2, but they have not released these images as yet. Their have also been reports from India stating that their images suggest the lander is still in one piece, but these reports are not confirmed.
LRO’s images should clarify the situation. The images should also help tell us what exactly happened after Indian engineers lost contact with Vikram shortly before landing.

More delays for China’s Long March 5
Chinese officials have now admitted that the next launch of China’s biggest but troubled rocket, the Long March 5, will not occur until December 2019 at the earliest.
Moreover, the first launch of Long March 5B, the new version of the rocket developed following the Long March 5 failure on its second launch in 2017, won’t happen until 2020. This is the version they plan to use to launch their space station modules, and these delays probably thus delay start of the in-orbit assembly of their space station by two years, to 2022.
These rocket delays also threaten the launch of China’s Chang’e-5 lunar sample return mission and their first Mars orbiting mission, which has a firm summer 2020 launch window which if missed will delay the mission’s launch for two years.
These reports also for the first time officially explain the engine trouble that caused the Long March failure on its second launch in July 2017.
Addressing the causes of the failure has required a lengthy process of redesign and testing of the YF-77 liquid hydrogen-liquid oxygen propellant engines. Two YF-77 engines power the rocket’s first stage, with an oxidizer turbopump isolated as the fault behind the 2017 launch failure.
The Space News article very strangely headlines the completion of the core module for China’s space station, when the real story here is the continuing delays in getting Long March 5 off the ground. Without that rocket none of China’s big space plans can proceed. Yet the article buries this scoop many paragraphs down. I wonder why.

China’s Long March 4B launches three satellites
China yesterday used its Long March 4B rocket to launch three satellites into orbit.
This was the first Long March 4 launch since May, when the third stage of a Long March 4C rocket failed. The main payload was a remote sensing satellite with both civilian and military applications. The second satellite was to provide ocean data and weather, with the third a cubesat testing new space communications and the use of a drag sail for de-orbiting.
The leaders in the 2019 launch race:
15 China
14 Russia
10 SpaceX
6 Europe (Arianespace)
The U.S. continues to lead China 19 to 15 in the national rankings.

Avalanche season at the Martian north pole
Click for full resolution image.
As the Martian spring started to unfold in April 2019, the focus of many Martian planetary scientists immediately shifted to the northern polar icecap, where they fully expected, based on previous experience, some spectacular events to occur.
I have already reported on this year’s initial observations of the sublimation of the carbon dioxide frost layer. That frost layer, generally less than six feet thick, falls as dry ice snow with the coming of winter, then sublimates away each spring. Since the arrival of Mars Reconnaissance Orbiter (MRO) in 2006 and its discovery of this process by its high resolution camera, these scientists have been monitoring the disappearance of that frost layer from Martian year to Martian year.
That sublimation process also brings with it other spectacular changes, including the coming of frequent avalanches along the high cliff scarps, ranging in heights from 1,500 to 3,000 feet, that comprise the edge of that north pole icecap. The image above, reduced to post here, shows one of the many avalanches found this spring and photographed as they were actually happening. It looks down at the cliff that runs from the left to the lower right of the image, with its top being the flat plateau in the lower left. From the caption, 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. (In the cutout, the top layer of the north polar cap is to the lower left.) The layers beneath are different colors and textures depending on the amount of dust mixed with ice.
The linear many-layered look of that cliff face is due to the many layers believed to exist within the permanent water icecap of Mars. To give some perspective, this cliff is several hundred feet taller than the World Trade Center after completion. Those falling blocks are dropping farther than the bodies that horribly fell from the Trade Center the day it was hit by airplanes flown by Islamic terrorists on September 11, 2001.
The map below shows most of the eastern half of that icecap, with the white boxes showing the various places MRO has spotted such avalanches.

Communications restored with Curiosity
Click for full resolution image.
With Mars moving out from behind the Sun yesterday, the Curiosity science team has successfully reestablished communications with the rover.
The focus of Curiosity’s activities since returning to operations after conjunction, now that Mars has safely moved out from behind the sun, is to finish up the analyses associated with the drilling campaign at “Glen Etive 1.”
The image to the right, cropped and reduced to post here, was among the first images downloaded from the rover once communications were reestablished. It was taken by a camera at the end of the robot arm that the scientists had positioned above the hole in order to get a close-up.
Before continuing up the mountain they now plan a second drill hole close-by, to better constrain the data at this location obtained from this first hole.

New Hubble image of Saturn
Click for full image.
Astronomers have used the Hubble Space Telescope to snap a new high resolution image of Saturn. That image, cropped and reduced to post here, can be seen on the right.
The image was part of a new Hubble program to obtain regular images of the outer planets, begun in 2018.
[The Saturn images] reveal a planet with a turbulent, dynamic atmosphere. This year’s Hubble offering, for example, shows that a large storm visible in the 2018 Hubble image in the north polar region has vanished. Smaller storms pop into view like popcorn kernels popping in a microwave oven before disappearing just as quickly. Even the planet’s banded structure reveals subtle changes in color.
But the latest image shows plenty that hasn’t changed. The mysterious six-sided pattern, called the “hexagon,” still exists on the north pole. Caused by a high-speed jet stream, the hexagon was first discovered in 1981 by NASA’s Voyager 1 spacecraft.
As beautiful as this Hubble photograph is, I cannot help but be saddened by it. It is now the best image of Saturn we will get until 2036 at the earliest, when a NASA mission to Titan finally arrives.

Video of the Japanese launchpad fire
I have embedded below the fold the video of the launchpad fire on September 10 that forced Japan to scrub the launch of its H-2B rocket carrying its HTV unmanned cargo freighter to ISS.
I set up the video to start just prior to the appearance of the fire, at 10 minutes in. Its appearance is quite dramatic. The video then continues for about twenty more minutes, showing the fire-fighting effort that brings the fire under control.
Japan’s space agency JAXA has still not released any further information about what caused the fire, the damage, or when they might reschedule the launch.

Relativity gets another launch contract
Capitalsm in space: The smallsat rocket company Relativity has signed another launch contract, this time with Momentus, a company making orbital smallsat tugs capable of transporting smallsats to higher orbits.
The launch agreement, announced during Euroconsult’s World Satellite Business Week here, covers one launch of Relativity’s Terran 1 rocket in 2021 with an option for up to five additional launches. The companies did not disclose the terms of the agreement, but Relativity offers the Terran 1 for a list price of $10 million.
The 2021 launch will fly Momentus’ Vigoride Extended tug, capable of carrying up to 350 kilograms of satellites. The tug will transport the satellites from an initial low Earth orbit to geostationary orbit using its water plasma thruster technology.
This is Relativity’s fourth launch contract, all signed prior to their first test launch. Right now they hope to start test flights late in 2020, with their first operational flights in 2021.
Momentus meanwhile adds a capability to all these smallsat rockets, essentially providing them an upper stage that will get the smallsats they launch from low Earth orbit to geosynchronous orbit.

Interstellar comet discovered?
An amateur astronomer has discovered what appears right now to be an interstellar comet making its approach into the solar system.
[I]mages show that the incoming object sports a faint but distinct coma and the barest hint of a tail — something ‘Oumuamua lacked — and thus appears to be a comet. Astronomers are no doubt eager to get spectra of the new find to determine what compounds might be escaping from its surface.
Based on current observations, C/2019 Q4’s eccentricity is about 3.2 — definitely hyperbolic. Objects on hyperbolic orbits are unbound to the Sun. They’re most likely to hail from beyond the solar system, flying in from great distances to pay our neighborhood a brief visit before heading off for parts unknown.
If this result holds up, astronomers have an unprecedented opportunity to study a potentially interstellar object in great detail over a long span of time. Based on the comet’s current magnitude (~18) and distance from the Sun (2.7 a.u.), it appears to be a fairly large object — perhaps 10 km or more across, depending on the reflectivity of its surface.
There remains a great deal of uncertainty about comet’s path, which will be better resolved with time and better data.
If it is a comet from beyond the solar system, it will be a spectacular goldmine for scientists, because its coma and tail will allow them to gather a great deal of information about its make-up, far more than they were able to gather about Oumuamua.

Jon David Kahn – American Heart
An evening pause: On this day of remembrance, this song seems fitting. And as the lyrics boldly state,
I won’t be made to ever feel ashamed
that I’m American made
I got American parts
I got American faith
In America’s heart
Go on, raise the flag
I got stars in in my eyes
I’m in love with her
And I won’t apologize.
The image that best reveals what America represents, as a messenger of freedom, is that photograph of the American soldier gently cradling a baby refugee from war. Or as said in the 1993 movie Gettysburg, “We are here for something new. This has not happened much in the history of the world. We are an army out to set other men free.”
Water found on exoplanet in habitable zone
The uncertainty of science: Astronomers now believe they have detected water in the atmosphere of an exoplanet that is also in habitable zone.
A new study by Professor Björn Benneke of the Institute for Research on Exoplanets at the Université de Montréal, his doctoral student Caroline Piaulet and several of their collaborators reports the detection of water vapour and perhaps even liquid water clouds in the atmosphere of the planet K2-18b.
…This exoplanet is about nine times more massive than our Earth and is found in the habitable zone of the star it orbits. This M-type star is smaller and cooler than our Sun, but due to K2-18b’s close proximity to its star, the planet receives almost the same total amount of energy from its star as our Earth receives from the Sun.
The size and mass of the this exoplanet means life as we know it probably does not exist there, either on its surface or in its atmosphere. Nonetheless, with water and the right amount of energy, anything is still possible.

Swamp attacks Trump over hurricane forecasts
Last week, as Hurricane Dorian approached the Florida coast, President Trump held a press briefing where he showed a graph with extra markings that suggested that Alabama might be impacted by the hurricane.
Unfortunately for Trump, this path for Dorian — though initially considered a possibility in the National Weather Service models — was also considered very unlikely, and had been quickly dismissed from those models, making Trump’s graph out-of-date when he showed it.
Since then the Democratic mainstream media has put out hundreds of stories claiming some sort of corruption on Trump’s part for adding those extra markings. Trump has himself responded aggressively, defending his action and saying it was justified. The New York Times even reported — based on anonymous sources — that Commerce secretary Wilbur Ross had threatened to fire three people at the National Weather Service if they didn’t issue a statement defending Trump.
Now, three former Democratic NOAA heads, D. James Baker (appointed by Bill Clinton), Jane Lubchenco (appointed by Barack Obama), and Kathryn D. Sullivan (appointed by Barack Obama), have issued a statement condemning Trump, claiming his actions are threatening the scientific integrity of these agencies.
The National Weather Service (NWS) has always been a model of scientific integrity, ensuring that weather science is not politically driven, regardless of the administration. But the recent misleading statements by President Donald Trump about a NWS hurricane forecast and cover-up actions by the National Oceanic and Atmospheric Administration (NOAA), its parent agency, have violated those norms.
Forgive me if I don’t take very seriously this smug, self-righteous posturing by these former NOAA officials, all partisan Democratic Party political appointees. Scientific integrity suddenly means a lot to them when they can use it to attack Trump. However, when NOAA repeatedly tampered with its climate data for the past dozen years, and has provided no good explanation for that tampering, I don’t remember these high and mighty officials, all in charge of NOAA at the time, commenting then about the importance of scientific integrity.
Trump is no saint here. He as a politician wanted to cover all bets, so he added Alabama in discussing Dorian’s threat, even though his weather scientists considered that threat slim if nonexistent. He should have relied more on those scientists and not improvised.
For him however to be attacked relentless for this minor addition is absurd, since it is perfectly reasonable for weather scientists to get their predictions wrong, and as president Trump has a responsibility to try to prepare for all eventualities.
These NOAA critics are far less credible however. There are questionable things going on at NOAA in connection with its global climate dataset that requires either an explanation or a correction. This is a far more serious issue than whether a politician expanded the threat of a hurricane in one press briefing in order to cover his ass. The tampering threatens to discredit the entire NOAA climate dataset, making all research based on it untrustworthy. If these former NOAA officials really cared about scientific integrity, they would have taken action at NOAA to deal with this tampering, when they ran those agencies. They would have either gotten it stopped, or provided the public and the rest of the scientific community a reasonable explanation for it.
They did neither, proving that their sanctimonious statement today is nothing more than partisan politics. They don’t care about scientific integrity. What they care about is defeating Trump, helping the Democratic Party, and enhancing the power of the Washington swamp.
More parachute problems for ExoMars 2020?
Space is hard: Eric Berger at Ars Technica reported yesterday that the parachute issues for Europe’s ExoMars 2020 mission are far more serious that publicly announced.
The project has had two parachute failures during test flights in May and then August. However,
The problems with the parachutes may be worse than has publicly been reported, however. Ars has learned of at least one other parachute failure during testing of the ExoMars lander. Moreover, the agency has yet to conduct even a single successful test of the parachute canopy that is supposed to deploy at supersonic speeds, higher in the Martian atmosphere.
Repeated efforts to get comments from the project about this issue have gone unanswered.
Their launch window opens in July 2020, only about ten months from now. This is very little time to redesign and test a parachute design. Furthermore, they will only begin the assembly of the spacecraft at the end of this year, which is very very late in the game.
When the August test failure was confirmed, I predicted that there is a 50-50 chance they will launch in 2020. The lack of response from the project above makes me now think that their chances have further dropped, to less than 25%.

Japan scrubs launch due to launchpad fire
Japan today scrubbed the launch of its unmanned HTV cargo freighter to ISS due to a launchpad fire that broke out only three and half hours before liftoff.
There is as yet no word on the cause of the fire, or how much damage it caused. Nor have they said anything about rescheduling the launch.
This would have been Japan’s second launch in 2019, a drop from the average of 4 to 6 in the last five years.

Taking a look back at a Martian pit
Click for full image.
The pit to the right could almost be considered the first “cool image” on Behind the Black. It was first posted on June 20, 2011. Though I had already posted a number of very interesting images, this appears to be the first that I specifically labeled as “cool.”
The image, taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO), had been requested by a seventh grade Mars student team at Evergreen Middle School in Cottonwood, California, and shows a pit on the southeastern flank of the volcano Pavonis Mons, the middle volcano in Mars’ well-known chain of three giant volcanoes. A close look at the shadowed area with the exposure cranked up suggests that this pit does not open up into a more extensive lava tube.
What inspired me to repost this image today was the release of a new image from Mars Odyssey of this pit and the surrounding terrain, taken on July 31, 2019 and shown below to the right.

The pit to the right could almost be considered the first “cool image” on Behind the Black. It was first posted on June 20, 2011. Though I had already posted a number of very interesting images, this appears to be the first that I specifically labeled as “cool.”
The image, taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO), had been requested by a seventh grade Mars student team at Evergreen Middle School in Cottonwood, California, and shows a pit on the southeastern flank of the volcano Pavonis Mons, the middle volcano in Mars’ well-known chain of three giant volcanoes. A close look at the shadowed area with the exposure cranked up suggests that this pit does not open up into a more extensive lava tube.
What inspired me to repost this image today was the release of a new image from Mars Odyssey of this pit and the surrounding terrain, taken on July 31, 2019 and shown below to the right.

SpaceX wins launch contract for seven SES satellites
Capitalism in space: SES yesterday announced that it has awarded SpaceX’s Falcon 9 the launch contract for the next seven satellites in its next generation communications constellation.
This is a big win for SpaceX, made even more clear by a briefing held yesterday with reporters by Arianespace CEO Stéphane Israel. In that briefing Israel outlined that company’s upcoming launch contracts, where he also claimed that this launch manifest is so full he had to turn down SES’s launch offer.
Because of its full manifest, Arianespace was unable to offer SES launch capacity in 2021 for its next generation of medium Earth orbit satellites, mPOWER. SES announced plans Sept. 9 to fly mPOWER satellites on SpaceX Falcon 9 rockets from Florida’s Cape Canaveral. Arianespace launched the 20 satellites in the SES O3B constellation.
It was important to SES to launch in 2021, Israel said. Given Arianespace’s full manifest, it was difficult “to offer the guarantee they were asking for,” he added.
If you believe that I have a bridge I want to sell you. Arianespace has been struggling to get launch contracts for its new Ariane 6 rocket. They have begun production on the first fourteen, but according Israel’s press briefing yesterday, Ariane 6 presently only has eight missions on its manifest. That means that six of the rockets they are building have no launch customers. I am sure they wanted to put those SES satellites on at least some of those rockets, and couldn’t strike a deal because the expendable Ariane 6 simply costs more than the reusable Falcon 9.

Yutu-2 travels almost 300 meters on ninth lunar day
According to a story today in official Chinese state-run media, Yutu-2 traveled another 284.99 meters during its ninth lunar day on the surface of the Moon, and has now been placed in hibernation in order to survive the long lunar night.
The story provides no further information, including saying nothing about the strange and unusual material the rover supposedly spotted during this time period.

Vector loses Air Force contract
Vector has withdrawn from an Air Force launch contract, allowing the military to reassign the contract to another new launch startup, Aevum.
The Agile Small Launch Operational Normalizer (ASLON)-45 space lift mission had been originally awarded to Vector Launch Aug. 7. But Vector formally withdrew Aug. 26 in the wake of financial difficulties that forced the company to suspend operations and halt development of its Vector-R small launch vehicle.
The Rocket Systems Launch Program — part of the Air Force Space and Missile Systems Center Launch Enterprise — used a Federal Acquisition Regulation “simplified acquisition procedure” to expedite another agreement with a different contractor, the Air Force said in a news release. Aevum’s contract is $1.5 million higher than the one that had been awarded to Vector.
The full scope of Vector’s problems still remain unclear. My industry sources tell me that there was absolutely no malfeasance at all behind the resignation of former CEO Jim Cantrell. From what I can gather, the problems appear to stem from issues of engineering with their rocket, combined with an investor pull-back due to those problems.
Either way, Vector is no longer among the leaders in the new smallsat launch industry, and in fact appears to be fading fast.

September 6, 2019 Zimmerman/Batchelor podcast
Embedded below the fold in two parts.
The first segment is especially worth listening to, as I blast the leftist mob rule that is killing TNT, advocating climate fraud, and is now trying to use that climate fraud, mostly by Democratic politicians, to advocate the destruction of freedom and our capitalist society. In fact, after we finished that segment John Batchelor took me to task for calling these Democrats “fascists” twice. John didn’t dispute my use of the word, nor was he trying to shut me up. He merely said using the word twice in one segment isn’t good radio, and to this I kind of agree.
Then again, these Democrats are fascists, and more people should be saying it.

Sunspot update August 2019: Even fewer sunspots
Last month I titled my sunspot update “Almost no sunspots,” as there were only two sunspots for the entire month of July, with one having the polarity for the next solar maximum.
August however beat July, with only one sunspot for the month, and none linked to the next maximum. To the right is the Silso graph of sunspot activity for August, showing just one sunspot for the month, on only one day, August 13.
Below is NOAA’s August graph of the overall sunspot cycle since 2009, released by NOAA today and annotated to give it some context.

Exploding nitrogen on Titan
A new theory proposes that some of the smaller high rimmed methane lakes on Titan were formed when underground nitrogen warmed and exploded, forming the basin in which the methane ponded.
Most existing models that lay out the origin of Titan’s lakes show liquid methane dissolving the moon’s bedrock of ice and solid organic compounds, carving reservoirs that fill with the liquid. This may be the origin of a type of lake on Titan that has sharp boundaries. On Earth, bodies of water that formed similarly, by dissolving surrounding limestone, are known as karstic lakes.
The new, alternative models for some of the smaller lakes (tens of miles across) turns that theory upside down: It proposes pockets of liquid nitrogen in Titan’s crust warmed, turning into explosive gas that blew out craters, which then filled with liquid methane. The new theory explains why some of the smaller lakes near Titan’s north pole, like Winnipeg Lacus, appear in radar imaging to have very steep rims that tower above sea level – rims difficult to explain with the karstic model.
This is a theory that has merit. It also must be treated with skepticism, as our knowledge of Titan remains at this time very superficial, even with the more detailed information garnered from Cassini.

Chandrayaan-2 locates Vikram
According to K. Sivan, the head of ISRO, India’s space agency, their Chandrayaan-2 orbiter has captured a thermal image of Vikram on the lunar surface, pinpointing the lander’s location.
They have not released the image. According to reports today, they do not yet know the lander’s condition, and have not regained communications. Reports late yesterday had quoted K.Sivan as saying “It must have been a hard-landing.” That quote is not in today’s reports.
In watching the landing and the subsequent reports out of India, it appears that India is having trouble dealing with this failure. To give the worst example, I watched a television anchor fantasize, twenty minutes after contact had been lost, that the lander must merely be hovering above the surface looking for a nice place to land. Most of the reports are not as bad, but all seem to want to minimize the failure, to an extreme extent.
Their grief is understandable, because their hopes were so high. At the same time, you can’t succeed in this kind of challenging endeavor without an uncompromising intellectual honesty, which means you admit failure as quickly as possible, look hard at the failure to figure out why it happened, and then fix the problem. If India can get to that place it will be a sign that they are maturing as a nation. At the moment it appears they are not quite there.

An evening pause: Kinda calm and relaxing.
Hat tip Thomas Biggar Rex Ridenoure of Ecliptic Enterprises.
Both have been generous with their suggestions, I just got them confused for this particular pause.
