Herb Alpert – Puttin’ on the Ritz

An evening pause: From the youtube page:

The Puttin’ On The Ritz music video is a creative collaboration between Alpert, artist Glenn Kaino and filmmaker Afshin Shahidi with choreographers Napoleon & Tabitha D’umo from So You Think You Can Dance and produced by Kerith Lemon. One long camera shot follows the lead dancer, Vincent Noiseux on a musical journey and features musicians Lani Hall, Bill Cantos, Hussain Jiffry and Michael Shapiro as well as corps dancers like Kherington Payne and others that have been seen on So You Think You Can Dance, America’s Best Dance Crew, Dancing with the Stars, This is It, Step Up and more.

Hat tip Tom Biggar, who notes that Albert makes some cameos, which I think includes both the bus driver and the bartender.

More potential Starship landing sites on Mars

Starship landing sites

On August 28, 2019 I broke the story that SpaceX is beginning to obtain images of candidate Starship landing sites from Mars Reconnaissance Orbiter (MRO).

Many news sources, skilled in their ability to rewrite press releases, saw my article and immediately posted stories essentially repeating what I had found, including my geological reasoning. Some did some more digging and, because they came out a few days later they were able to take advantage of the next MRO team image release, issued on August 30th, to find a few more candidate site images.

Those additional images included the remaining stereo images for all the images in my August post, indicated by the white boxes in the overview map above. They also included two new locations, indicated by the black boxes. One was of one more location in the easternmost hills of Erebus Montes. The other was a stereo pair for one entirely different landing location, farther to the west in the mountains dubbed Phlegra Montes, a location that SpaceX had previously been considering, but until this image had not been included in its MRO image requests.

The grey boxes in the map above show the approximate locations of images not yet officially released by MRO. Though unreleased, their existence is still public knowledge, as they are listed as already acquired images in the HiWish database. Below are links to the three upcoming new images (the second stereo images for locations #1 and #2 are not included)

Both the Phlegra Montes location and #3 above appear to be looking at soft slushy material that might have a lot of water just below the surface.

Stony-iron asteroid caused flash on Jupiter in August

According to an analysis of the data obtained from the light flash that occurred when an object hit Jupiter on August 7, scientists have estimated its probably make-up, mass, and size.

They estimate from the energy released by the flash that the impactor could have been an object around 12-16 metres in diameter and with a mass of about 450 tons that disintegrated in the upper atmosphere at an altitude of about 80 kilometres above Jupiter’s clouds. Sankar and Palotai’s models of the light-curve for the flash suggest the impactor had a density typical of stony-iron meteors, indicating that it was a small asteroid rather than a comet.

Their conclusions are strengthened because they were able to compare this flash with five other similar but not as bright flashes, all detected since 2010.

These recent detections, all by amateurs, are because of the higher quality equipment now available to ordinary people, including the use of computers and remote operation. This technology is making it possible for amateurs to discover things that once only professionals could find.

The Democratic/Media smear machine

This past weekend we got to once again see the workings of the Democratic/Media smear machine, designed to not only destroy the reputation of anyone who opposes them, but to give that machine justification for removing all such individuals from any position of power.

All without any evidence. None.

First the New York Times published a new unsubstantiated smear against Supreme Court justice Brett Kavanaugh. The allegations were made by a Democratic Party operative who had acted as one of Bill Clinton’s lawyers, and who claimed to have seen the incident.

Then Democratic politicians pile on, demanding the impeachment of Kavanaugh. They do this despite the fact that there are absolutely no other confirmed witnesses to that Democratic operative’s accusations. Nor is there any record anywhere or evidence that the vile incident ever happened.

Then, when the damage has already been done, and this new Big Lie has been properly spread throughout the world, the New York Times finally corrects its initial report, adding two significant details that discredits the report entirely. First, the so-called victim had refused to be interviewed for the report, and second, according to her friends, has no recollection of the incident itself.

None of these corrections will matter. From now on Democrats, and their willing allies in the press, will repeatedly use this new smear as evidence that Kavanaugh is a bad person who must be removed from office.

This is the same pattern we have seen them use repeatedly for the past decade. First they make unsubstantiated accusations of racism (the Tea Party, some children from Kentucky), of murder (Trayvon Martin, Michael Brown), of encouraging violence (Sarah Palin), of treason (Trump), of sexual deviancy (Kavanaugh and Roy Moore), and then when those accusations are unequivocally proven to be lies and smears, ignore this fundamental evidence to continue spreading the lies and the slanders.

Yet, when it came time to vote in 2018, the American public shrugged its shoulders, ignored this vile behavior, and rewarded these Democrats with more power in Congress. It seems that a very large percentage of the American public — maybe even a majority — approves of this smear machine, likes what it is doing, and wants to use it to make sure all opposition to the Democratic Party is destroyed, by any means necessary.

Bad times are coming, unless something changes in the 2020 election.

Hayabusa-2 dropping orbiting target marker

In preparation for the release and landing of Hayabusa-2’s second MINERVA-II2 tiny rover/bouncer, the spacecraft today began a close-approach to the asteroid Ryugu, where it will release two target markers.

Once released, Hayabusa-2 will back off to observe these markers as they spiral down into Ryugu, landing sometime around September 23.

This operation is a rehearsal for the release and landing of MINERVA-II2, which like the first two bouncers back in September 2018 will bounce along the asteroid’s surface, taking pictures and gathering data.

Update on effort to save heat probe on InSight

Link here. The article, written in late August by one of the German scientists in charge of the heat probe on the Mars lander InSight, gives a detailed look at the effort to figure out what is blocking the Mole, the digging tool designed to pound the heat probe as much as 15 feet into the ground.

They had discovered previously is that the ground had collapsed around the drill shaft, creating a very wide hole. The Mole however needed the friction caused by the surrounding dirt to push downward, and thus didn’t have it.

They have since used InSight’s scoop at the end of the robot arm to push at the ground around the hole in an effort to fill the hole. As of mid-August this has managed to fill the hole about half way.

This report was written on August 27, just before contact with Mars was lost for two weeks because the Sun had moved between the Earth and Mars. Communications have now resumed, so I expect they will also resume their efforts to fill the hole enough that they might then try to resume the digging effort.

Buy dumb!

The dumb washing machine we hunted for and got
The used “dumb” machine we
paid $285 for that actually
cleans our clothes.

The smart washing machine we threw out
The “smart” machine that we
paid $923 for and sold for $40.

Two years ago our old Kenmore Series 80 washing machine broke down. The repair guy said it would be so expensive to fix that he recommended it was time to buy something new.

So off we went to Sears, where we ended up buying one of today’s modern “smart” machines for a mere $923. As the LG website proudly exclaims,

A Smarter Way to Wash: 6Motion™ Technology uses up to 6 different wash motions to provide a smart cleaning experience that is gentle on clothes and maximizes washing performance.

The problem was the machine never got any of our clothes clean. It also refused to provide enough water. The way it worked was to sense the weight of the clothes you put inside, and determine the needed amount based on this. Routinely, it wasn’t enough, so Diane did web searches to discover numerous owners faking out the machine’s brains by pouring several buckets of water on top of the clothes before turning on the machine, making them weigh more.

The machine also did not have an agitator, the new in-thing among washing machine manufacturers two years ago, probably forced on them by new federal regulations. And though the tub itself did shake, it did it so gently that the clothes hardly moved.

There were also other issues with the machine’s smart technology that frustrated Diane. The machine was boss, and would not allow for any flexibility to its predetermined wash and rinse cycles, even when they made no sense.

Last week Diane had had enough. » Read more

UAE’s first manned flight launches this week on Soyuz

This article provides a nice detailed Arab perspective on the upcoming September 25 launch of the United Arab Emirates’ (UAE) first manned mission, sending one of their jet fighter pilots on a Soyuz to ISS for about a week.

The article not only also reviews the entire history of past Arab astronaut missions in space, the first on an American shuttle in 1985 and the second on a Soyuz in 1987, it summarizes the present-day space-related efforts throughout the Arab world, not just in the UAE. Good information in advance of this week’s upcoming launch.

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

Comet Borisov
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

Avalanche on-going at the edge of Mars' north pole icecap
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

The most recent Curiosity drill hole
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

Saturn taken by Hubble in 2019
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.
