Celebrating Apollo 12

The Apollo 12 landing site on the Moon
Click for the full resolution image.

Fifty years ago today Apollo 12 was launched, landing on the Moon several days later to become the second manned mission to land on another world.

To celebrate that achievement, let’s review a few of the mission’s high points. The image to the right, cropped and reduced to post here, shows that landing site, the lunar module Intrepid, the various tracks for the two moon-walks Pete Conrad and Alan Bean took, and the unmanned Surveyor-3 probe. The image was taken by Lunar Reconnaissance Orbiter late in 2011 and released to the public in 2012. To really see some detail you will look at the full resolution version by clicking on the image. Or you can explore the landing even more thoroughly at the original release site.

First, there was Pete Conrad’s point blank landing. They wanted to land close enough to Surveyor 3 so that the two astronauts would be able to walk over to it during a spacewalk. He did this perfectly, bringing Intrepid down only 600 feet away. They were thus able to recover the probe’s scoop, camera, television cable, and other assorted parts. Once back on Earth the big discovery was that a single bacterium, Streptococcus mitis, had survived the journey from Earth and was still alive upon its return. Scientists theorized its survival occurred because prior to launch it had been freeze-dried during prelaunch vacuum tests.

Second, there were Pete Conrads’s first words upon stepping off the lunar module. As the third man to walk on the Moon and also one of the shortest Apollo astronauts, he won a bet with a French reporter, who did not believe he had the freedom to say whatever he wanted as his first words, by saying, “Whoopee! Man, that may have been a small step for Neal, but it’s a long one for me!”

Third, the astronauts installed the second seismometer on the Moon, which functioned for eight years.

Fourth, they brought back 75 pounds of material, which showed that while the Ocean of Storms was a mare lava field like the Sea of Tranquility, it had formed 500 million years more recently.

Fifth and most important, Apollo 12 proved that the Apollo 11 landing was not a fluke, that the engineering behind the Saturn 5 rocket, the Apollo capsule, and the lunar module, was sound. With courage and determination and a little clever re-engineering, those vehicles had been capable of taking humans anyway in the solar system. It is a shame we never took advantage of that possibility.

Upcoming big satellite constellations vex and worry astronomers

Astronomers are expressing increasing distress over the possible negative consequences to their Earth-based telescope observations from the several new giant satellite constellations being launched by SpaceX and others.

[M]any astronomers worry that such ‘megaconstellations’ — which are also planned by other companies that could launch tens of thousands of satellites in the coming years — might interfere with crucial observations of the Universe. They fear that megaconstellations could disrupt radio frequencies used for astronomical observation, create bright streaks in the night sky and increase congestion in orbit, raising the risk of collisions.

The Nature article then details the issues faced by some specific telescopes. Hidden within the article however was this interesting tidbit that admitted the problem for many telescopes is really not significant.

Within the next year or so, SpaceX plans to launch an initial set of 1,584 Starlink satellites into 550-kilometre-high orbits. At a site like Cerro Tololo, Chile, which hosts several major telescopes, six to nine of these satellites would be visible for about an hour before dark and after dawn each night, Seitzer has calculated.

Most telescopes can deal with that, says Olivier Hainaut, an astronomer at the European Southern Observatory (ESO) in Garching, Germany. Even if more companies launch megaconstellations, many astronomers might still be okay, he says. Hainaut has calculated that if 27,000 new satellites are launched, then ESO’s telescopes in Chile would lose about 0.8% of their long-exposure observing time near dusk and dawn. “Normally, we don’t do long exposures during twilight,” he says. “We are pretty sure it won’t be a problem for us.” [emphasis mine]

The article then proceeds with its Chicken-Little spin as if the astronomical world is about to end if something is not done to stop or more tightly control these new satellite constellations.

As indicated by the quote above, it appears however that the threat is overstated. The constellations might reduce observing time slightly on LSST, scheduled for completion in 2022 and designed to take full sky images once every three nights. Also, the satellite radio signals might impact some radio astronomy. In both cases, however, the fears seem exaggerated. Radio frequencies are well regulated, and LSST’s data should easily be able to separate out the satellite tracks from the real astronomical data.

Rather than demand some limits or controls on this new satellite technology, the astronomical community should rise to the occasion and find ways to overcome this new challenge. The most obvious solution is to shift the construction of new telescopes from ground-based to space-based. In fact, this same new satellite technology should make it possible for them to do so, at much less cost and relatively quickly.

But then, astronomers are part of our modern academic community, whose culture is routinely leftist and therefore fascist in philosophy (even though they usually don’t realize it). To them too often the knee-jerk response to any competition is to try to control and squelch it.

We shall see if the astronomers succeed in this case.

Both methane and oxygen fluctuate in unison seasonally in Gale Crater

The uncertainty of science: According to a new science paper, data from Curiosity on Mars has now found that both methane and oxygen fluctuate in unison seasonally in Gale Crater.

From the paper’s abstract:

[T]he annual average composition in Gale Crater was measured as 95.1% carbon dioxide, 2.59% nitrogen, 1.94% argon, 0.161% oxygen, and 0.058% carbon monoxide. However, the abundances of some of these gases were observed to vary up to 40% throughout the year due to the seasonal cycle. Nitrogen and argon follow the pressure changes, but with a delay, indicating that transport of the atmosphere from pole to pole occurs on faster timescales than mixing of the components. Oxygen has been observed to show significant seasonal and year‐to‐year variability, suggesting an unknown atmospheric or surface process at work. These data can be used to better understand how the surface and atmosphere interact as we search for signs of habitability.

The data shows that the unexpected and so far unexplained seasonal oxygen fluctuation appears to track the same seasonal methane fluctuations. While biology could cause this signature, so could geological processes, though neither can produce these fluctuations easily.

Meanwhile, adding to the uncertainty were results from the two European orbiters, Mars Express and Trace Gas Orbiter. Both have failed to detect a June 19, 2019 dramatic spike in methane that had been measured by Curiosity.

China unveils Mars lander during landing simulation test

The new colonial movement: China today unveiled to the international press its first prototype Mars lander, showing it attempting a simulated controlled descent on a gigantic test stand.

The demonstration of hovering, obstacle avoidance and deceleration capabilities was conducted at a site outside Beijing simulating conditions on the Red Planet, where the pull of gravity is about one-third that of Earth.

China plans to launch a lander and rover to Mars next year to explore parts of the planet in detail.

This is the first time I have heard anything about China sending a lander/rover to Mars in 2020. Previously the reports had discussed only sending an orbiter.

I have embedded video of the test below the fold. It shows the prototype hanging by many wires from the test stand, then dropping quickly, with its engine firing, before stopping suddenly, followed by an engine burst. While impressive, it did not strike me that China is even close to sending this spacecraft to Mars. The test only proved the spacecraft’s ability to do some maneuvering during descent. It did not show that it could land.

That the project’s designer said that landing would take “about seven minutes” also suggests that they are copying the techniques used by JPL to land Curiosity. Considering that JPL’s computers have been repeatedly hacked, including some hacks identified as coming from China, it would not surprise me if China has simply stolen those techniques.

I still expect them to launch an orbiter to Mars in 2020. Whether they also send a lander and rover remains to be seen.

India targets Nov 2020 for new lunar lander mission

The new colonial movement: Sources inside India’s space agency ISRO yesterday revealed that they are now working to build and fly another lunar lander/rover, dubbed Chandrayaan-3, with a target launch date of November 2020, only one year from now.

Isro has formed multiple committees — an overall panel and three sub-committees — and held at least four high-level meetings since October. The new mission will include only a lander and rover, as the Chandrayaan-2 orbiter is functioning well. On Tuesday, the overview committee met with the agenda of reviewing the configuration of Chandrayaan-3. It also looked into the recommendations of various sub-committees on propulsion, sensors, overall engineering, navigation and guidance.

The Chandrayaan-2 orbiter had provided the propulsion capabilities to get the Vikram lander (with rover) to lunar orbit earlier this year, only to have the lander fail shortly before touchdown. To do this new mission without an orbiter will require adding a propulsion unit to the rover/lander. They are also looking at strengthening the lander’s legs to better resist a high velocity landing.

Kudos to ISRO for moving so quickly. There is no reason a replacement lander/rover should take years to build. They already know what to do, they need only do it again, with upgrades designed to avoid the failure in September.

SpaceX completes Crew Dragon static fire tests

SpaceX yesterday successfully completed a static fire engine test of its Crew Dragon capsule, demonstrating that it has fixed the issues that caused the April 20th explosion during an earlier test that destroyed a capsule.

Wednesday’s test occurred just 207 days after the April anomaly, a quick turnaround time given the complexity of the systems at hand. The incident earlier this year occurred just milliseconds before the engines were to have ignited, and was eventually traced to valves leaking propellant into high-pressure helium lines.

SpaceX made numerous changes to Crew Dragon as a result of the anomaly, including the replacement of the valves with burst-discs. The company has also been performing several smaller-scale tests of the redesigned system at their test facility in McGregor, Texas. Last month, SpaceX Tweeted a video of one such test.

Wednesday’s test was the first full-scale firing of all eight of Crew Dragon’s SuperDraco’s at once since the April incident.

This success clears the way for the launch abort test using this same capsule, now tentatively scheduled for mid-December.

SpaceX completes 1st round of Starship’s Mars landing site images

All locations photographed of the candidate landing region for SpaceX's planned Mars missions

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).

It now appears that SpaceX has completed its first round of Starship requests from MRO. In the image releases from Mars Reconnaissance Orbiter (MRO) since September, only three new Starship locations were taken, and all three were the unreleased candidate sites I noted in my September 16, 2019 update.

Below is the full list of all of the Starship images, their locations indicated on the map above by the numbered white boxes:

With the release of these last photographs, the initial list of proposed images of candidate Starship landing sites on Mars has apparently been completed. No additional images at any other locations appear to have been suggested. The MRO science team has taken stereo images of each one of the nine locations, eight of which were in Amazonis Planitia, and one in Phlegra Montes.

This however is not the first round of pictures requested by SpaceX of the Arcadia Planitia region in connection with the company’s desire to land spacecraft on Mars.

Click for full image.

The Chandrayaan-2 science team today released several new images from the spacecraft, while also showcasing their ability to use those images to produce 3D oblique simulations, as shown to the right. This oblique view of Lindbergh Crater was created from an overhead view using computer software that estimated the elevations from the image.

The spacecraft’s high resolution camera can resolve objects as small as sixteen feet across, which is the best resolution yet for any lunar orbiter.

No word yet on whether they have been able to find and image their failed Vikram lander.

Hayabusa-2 begins journey back to Earth

The Hayabusa-2 science team has fired up the spacecraft’s ion engine to leave the asteroid Ryugu and began its begins journey back to Earth.

It will take about six days to exit the gravitational sphere of influence of Ryugu. During that time period they will be continually releasing real time images of the asteroid from the spacecraft’s navigation camera, as it slowly gets farther away.

In mid-December they will fire the spacecraft’s main engines for an arrival near Earth in late 2020. At that point the small return capsule holding the samples from Ryugu will separate and land in the Australian desert. Hayabusa-2, still operational, might then be given a new subsequent mission.

Virgin Galactic reports first loss since stock went public

Capitalism in space: Virgin Galactic today released its first quarterly report since the company’s stock went public in October, reporting a net loss of $51.5 million during the third quarter of 2019.

The stock initially opened in October at $12.93. It quickly dropped 25% in value, and has generally been trading at about $10 a share since. With today’s release the stock immediately dropped below $10, but it appears to have settled at around $9.75, for the moment.

According to this story, they presently have reservations from 600 people for suborbital flights, and have received 3,557 inquiries about flight reservations as of the end of September.”

Parker releases first data to public

Having completed its first three orbits of the Sun, the Parker Solar Probe science team today made all the data obtained available to the public.

The image to the right was taken during the first close solar flyby in November 2018. It shows solar wind particles streaming past the spacecraft.

Do not expect many spectacular images from Parker. It has a camera, but the mission’s focus is the study of the Sun’s atmosphere and solar wind, neither of which are likely to be very photogenic.

No manned New Shepard flights in 2019

In an interview with CNBC, Bob Smith, the CEO of Blue Origin, revealed that the first manned flights of New Shepard will not take place in 2019, as previously predicted.

Smith: We were planning on this year; unfortunately, it’s very unlikely we’re going to get in this year. We need a few more flights to make sure that we’re all comfortable with the verification. We hold ourselves to very, very high standards here, we’re never going to fly until we’re absolutely ready. I think we have a very, very good amount of confidence around the system itself, I think it is working very, very well. But we have to go look at all the analysis, and then convince ourselves that we’re ready to go. … So it probably will be next year.

This statement confirms what Smith said in late September. However, though he says they need to do a few more unmanned test flights, they have not done one since May, suggesting there was some issue during that last flight that they aren’t telling us about.

The interview overall contains little concrete information, and in fact suggests that the company’s orbital rocket, New Glenn, is likely not going to meet its 2021 launch target. When asked when he expects their rocket factory in Huntsville to begin building 40 engines a year, he said, “when we are at-rate and flying, so in ’22 and ’23. We are opening the factory there this coming first quarter.”

That 2021 date was a delay of a year from the original goal of 2020. That they won’t be opening their rocket factory until 2020, and won’t be operational until 2022 or 2023, suggests this entire schedule is out the window. I will not be surprised if there are no New Glenn flights before 2023.

China completes two launches today

In a space of three hours today China successfully completed two launches. First, a Kuaizhou-1A rocket, intended for commercial launches, placed a civilian Earth resource satellite into orbit. Then, a Long March 6 rocket put five remote sensing satellites into orbit.

The leaders in the 2019 launch race:

24 China
17 Russia
11 SpaceX
6 Europe (Arianespace)

With these two launches China has leap-frogged past the U.S. to take the lead in the national rankings, 24 to 23.

Polygons on Mars

Scallops and polygons on Mars
Click for full image.

Cool image time! The photograph on the right, cropped to post here, was taken on September 25, 2019 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and made public in its November image release. It shows the weird but very typical scalloped terrain, with its adjacent polygon pattern of fractures, found routinely in the northern lowland plains of Utopia Planitia on Mars. From an earlier captioned image from 2006 of these same features:

The scalloped depressions are typical features; a smooth layered terrain located between 40 and 60 degrees in both hemispheres. Scalloped depressions probably form by removal of ice-rich subsurface material by sublimation (ice transforming directly from a solid to a gaseous state), a process that may still be active today. Isolated scalloped depressions generally have a steep pole-facing scarp and a gentler equator-facing slope. This asymmetry is interpreted as being the result of difference in solar heating. Scalloped depressions may coalesce, leading to the formation of large areas of pitted terrain.

The polygonal pattern of fractures resembles permafrost polygons that form in terrestrial polar and high alpine regions by seasonal-to-annual contraction of the permafrost (permanently frozen ground). On Earth, such polygons indicate the presence of ground ice.

On Earth these polygons are most often seen in mud, usually suggesting a drying process where the ground contracts with the lose of fluid. On Mars the cracks probably also form from contraction, but not by the lose of fluid but the lose of water ice as it sublimates into a gas.

These polygons and scallops illustrate an important feature of Mars’ vast northern plains. On large scales these plains appear flat and featureless. Up close however many many strange features, like the polygons and scallops in this image, come into view.

New Horizons team renames “Ultima Thule” to “Arrokoth”

The New Horizons team has renamed the Kuiper Belt object that the spacecraft flew past on January 1, 2019 from its informal nickname of “Ultima Thule” to “Arrokoth,” which means “sky” in Powhatan/Algonquian language.

This official, and very politically correct, name has apparently gotten the stamp of approval from the IAU.

In accordance with IAU naming conventions, the discovery team earned the privilege of selecting a permanent name for the celestial body. The team used this convention to associate the culture of the native peoples who lived in the region where the object was discovered; in this case, both the Hubble Space Telescope (at the Space Telescope Science Institute) and the New Horizons mission (at the Johns Hopkins Applied Physics Laboratory) are operated out of Maryland — a tie to the significance of the Chesapeake Bay region to the Powhatan people.

“We graciously accept this gift from the Powhatan people,” said Lori Glaze, director of NASA’s Planetary Science Division. “Bestowing the name Arrokoth signifies the strength and endurance of the indigenous Algonquian people of the Chesapeake region. Their heritage continues to be a guiding light for all who search for meaning and understanding of the origins of the universe and the celestial connection of humanity.” [emphasis mine]

It is a good name, especially because its pronunciation is straight-forward, unlike the nickname.

The blather from Glaze above, however, is quite disingenuous. The Algonquian people have had literally nothing to do with the modern scientific quest for “meaning and understanding of the origins of the unverse.” They were a stone-age culture, with no written language. It was western civilization that has made their present lives far better. And it was the heritage of western civilization, not “the indigenous Algonquian people” that made the New Horizons’ journey possible. Without the demand for knowledge and truth, as demanded by western civilization, we would still not know that Arrokoth even existed.

Putin slams Roscosmos for continuing corruption at Vostochny

At a meeting yesterday Russian President Vladimir Putin blasted Roscosmos for the corruption at the new spaceport at Vostochny, noting that despite the prosecution of numerous individuals the criminal behavior continues.

Russian President Putin said at a government meeting on Monday that dozens of criminal cases and jailings had failed to stem theft at the Vostochny spaceport construction site….

“It has been stated a hundred times: you must work transparently because large funds are allocated. This project is actually of the national scope! But, despite this, hundreds of millions, hundreds of millions [of rubles] are stolen! Several dozen criminal cases have been opened, the courts have already passed verdicts and some are serving their prison terms. However, things have not been put in order there the way it should have been done,” the Russian president said.

This article notes that out of $1.4 billion allocated for the spaceport, $169 million has been stolen. It does not however provide any details about any new corruption. Instead, it outlines the investigations and prosecutions that have already taken place.

According to Peskov, “at the first stage, 128 criminal cases were opened, which were later consolidated into 32 criminal cases and at the next stage the Investigative Committee singled out 21 cases and transferred them to the court of law and 18 persons were sentenced at the time,” Peskov said. “The Interior Ministry investigated 8 more cases,” he added.

Either Roscosmos officials revealed to Putin newly discovered corruption that the state-run press has been forbidden to discuss, or Putin’s criticism was aimed to discouraging future corruption.

Either way, Vostochny remains a typical government boondoggle. It has cost Russia far more than it should, and construction has been slow, beginning officially in 2012, though Russia has been working on it in fits and starts since the mid-2000s.

Hayabusa-2 to begin return voyage on November 13

In a press conference today the science team for the asteroid probe Hayabusa-2 announced that the spacecraft will begin the first stage of its journey back to Earth tomorrow, using its ion engine to slowly pull away from Ryugu.

That first stage will take a little less than a week. Once the spacecraft gets about 25 miles from Ryugu it will leave its sphere of gravitational influence, when it will then begin its cruise phase back to Earth.

Mars’ seasonally vanishing carbon dioxide polar cap

Buzzell dunes, March 19, 2019
Click for full image.

Since the onset of the Martian spring in the northern hemisphere back in March of this year, scientists have been busy using the high resolution camera on Mars Reconnaissance Orbiter (MRO) to monitor the expected sublimation and disappearance of the cap of dry ice that falls as snow to become a winter layer mantling both the more permanent icecap of water 7,000 feet deep as well as the giant dune sand seas that surround that northern icecap.

The image on the right was first posted here on Behind the Black on June 6, 2019 as part of a long article describing that northern polar icecap and its annual evolution. It shows a set of dunes that Candice Hansen of the Planetary Science Institute in Arizona, who requested the image, has dubbed “Buzzell.” When that picture was taken in March, the frozen dry ice layer of translucent carbon dioxide still coated the dunes. The image’s darkness is because the Sun has just begun to rise above the horizon at this very high latitude location (84 degrees). The circular feature is likely a buried ancient crater, with the streaks indicating the prevailing wind direction blowing both sand and frost about.

On August 9, 2019 I provided an update on this monitoring, when new images of this same location were downloaded from MRO in April and June. MRO has now taken a new image of Buzzell, on October 2, 2019. Below the fold are all these images so that you can see the sublimation and disappearance of that dry ice layer over time.

SpaceX successfully launches 60 Starlink satellites

Capitalism in space: SpaceX today successfully launched 60 more satellites in its Starlink internet satellites, while also reusing for the first time a Falcon first stage for a fourth time, reusing a fairing for the first time. The first stage successfully completed a barge landing. No word on whether they were able to recover the fairings.

I have embedded the replay of the live stream below the fold. They now have proved the capability of recovering and reusing 70% of their rocket.

The leaders in the 2019 launch race:

22 China
17 Russia
11 SpaceX
6 Europe (Arianespace)

The U.S. now leads China 23 to 22 in the national rankings.

Bennu & Ryugu: Two very old and strange asteroids

Bennu as seen by OSIRIS-REx
Bennu’s equatorial ridge. Click for full image.

This week the science team operating the OSIRIS-REx spacecraft at the asteroid Bennu hosted a joint conference in Tucson, Arizona, with the scientists operating the Hayabusa-2 spacecraft at the asteroid Ryugu. Both gave up-to-date reports on the science so far obtained, as well as outlined upcoming events. I was fortunate enough to attend.

First an overview. Both Bennu and Ryugu are near earth asteroids, with Bennu having an orbit that might even have it hit the Earth in the last quarter of 2100s. Both are very dark, and are rubble piles. Both were thought to be of the carbonaceous chondrite family of asteroids, sometimes referred to as C-type asteroids. This family, making up about 75% of all asteroids, includes a bewildering collection of subtypes (B-types, F-types, G-types, CI, CM, CV, CH, CB, etc), all of which were initially thought to hold a lot of carbon. We now know that only a few of these categories, the CI and CM for example, are carbon rich.

Even so, we actually know very little about these types of asteroids. They are very fragile, so that any that reach the Earth’s surface are not a good selection of what exists. About 90% of the material gets destroyed in the atmosphere, with the remnant generally coming from the innermost core or more robust nodules. We therefore have a biased and limited sample.

It is therefore not surprising that the scientists are finding that neither Bennu nor Ryugu resembles anything else they have ever seen. Both have aspects that resemble certain types of carbonaceous chondrite asteroids, but neither provides a very good fit for anything.

New InSight image of mole shows collapse of hole

View of InSight drill hole
Click for full movie.

The InSight science image has lifted the lander’s rover arm off the drill hole and taken a new series of images in an effort to discover what caused the mole to pop out during its most recent drilling effort.

The image to the right, cropped to post here, was the first in a short movie made from all the images taken over the course of a day. The sequence shows the change in shadows, which helps define the situation in the hole.

This image however I think tells all. It shows that the walls of the hole have collapsed all around the mole, widening it further. It also shows that, once the mole popped out to lean sideways against the left wall, much of that material then fell into the hole, refilling it. These facts are very evident when today’s image is compared with this image from October, taken prior to the most recent drilling effort. The hole has become much wider, there is more material inside it, and the mole is now much farther out.

All these facts bode ill for the mole ever succeeding in drilling down the planned fifteen or so feet to insert a heat probe into the interior of Mars in order to take the first ever measure of the planet’s interior.

An overall assessment of this NASA mission is not very positive. The contribution from its international partners is especially bad. The mission was launched two years late because the French effort to build the seismometer failed. NASA had to subsequently give the job to JPL to get it done. Now the heat sensor is a failure, because the German-built mole has failed to get the heat sensor where it needs to be.

The seismometer and heat sensor were InSight’s only science instruments. This means that we will likely only get results from one.

More detail on pad abort test parachute issue

At a press telecon yesterday Boeing outlined in more detail the cause of the failure of one main parachute to deploy during its November 4 Starliner pad abort test.

In a call with reporters, John Mulholland, vice president and program manager for commercial crew at Boeing, said an investigation after the Nov. 4 test at White Sands Missile Range in New Mexico led the company to conclude that a “lack of secure connection” between a pilot parachute and the main parachute prevented that main parachute, one of three, from deploying.

The pilot parachute is designed to deploy first, and pull out the main parachute. However, Mulholland said that hardware inspections and photographs taken during “closeout” of the vehicle prior to the test showed that a pin that links the pilot and main parachutes was not inserted properly.

“It’s very difficult, when you’re connecting that, to verify visually that it’s secured properly,” he said, in part because that portion of the parachute system is enclosed in a “protective sheath” intended to limit abrasion but which also makes it difficult to visually confirm the pin is in place. “In this particular case that pin wasn’t through the loop, but it wasn’t discovered in initial visual inspections because of that protective sheath.”

Mulholland said Boeing is modifying assembly procedures through what he called “fairly easy steps,” such as pull tests, to ensure those pins are properly installed. Technicians have already confirmed that the same parachute linkages are properly installed on the three parachutes on the Starliner that will launch in December on an orbital flight test to the International Space Station. [emphasis mine]

That a hardware inspection and photos taken before launch revealed this issue and resulted in nothing being done should rise serious questions at Boeing about its quality control processes. Based on the press telecon, however, it does not appear that Boeing is asking those questions. From a different report:

[John Mulholland, Boeing’s Starliner program manager] praised the rigging team, saying “even before we got eyes on the hardware, that team on their own initiative (was) reviewing the close-out photos and the processes, and they identified the potential issue that was subsequently validated by hardware inspection.”

“Most importantly, they raised their hand and and let us know what they believe the problem was,” he said. “It’s really a testament to the transparency of that team. The speak-up culture that we have, that is what we need on this program.”

While it is good that the rigging team was willing to speak up afterward, it is very bad that their procedures allowed the launch to go forward. The company says it has now changed its rigging procedures, but I don’t sense any effort on Boeing’s part to find out why its so-called “speak-up culture” failed to have these engineers speak-up, before launch.

New video of Starliner pad abort test

Boeing has released a new video of the Starliner pad abort test on November 4th, showing the full flight.

I have embedded the footage below the fold. The one aspect of this test that I have as yet not seen any explanation for is the red cloud to the left of the capsule’s touch down spot. It surely looks like the kind of smoke one sees from the release of certain toxic fuels. It was also something that the live stream video focused on, suggesting the possibility that its existence was important and needed to be recorded for engineering reasons.

Regardless, the fact that any onboard astronauts would have been safely returned to Earth, based on this test, should mean Boeing’s abort system is functioning properly. They note that they have pinpointed the reason one parachute did not deploy (“attributed to the lack of a secure connection between the pilot chute and one of the main chutes”), a problem that is probably quite simple to fix. Hopefully that one failure will not cause any significant delays in their future flights, including the first manned flight next year.

White House: Cost for each SLS launch is $2 billion

According to the Office of Management and Budget (OPM), the cost for each SLS launch is now estimated to equal $2 billion.

This is the first time anyone in the executive branch has put a number to the SLS per launch cost. NASA has always refused to give a number, for good reason, since this price compares so horribly with even the most expensive private rocket (generally more than $200 million for the biggest members of the Delta rocket family). The Falcon Heavy costs about $100 million, so that to get the same mass into orbit would require two launches, but that would still be only $200 million, one tenth the cost.

The article then notes how this cost is affecting the Europa Clipper mission, which has three launch options, with SLS mandated by Congress.

The powerful SLS booster offers the quickest ride for the six-ton spacecraft to Jupiter, less than three years. But for mission planners, there are multiple concerns about this rocket beyond just its extraordinary cost. There is the looming threat that the program may eventually be canceled (due to its cost and the emergence of significantly lower cost, privately built rockets). NASA’s human exploration program also has priority on using the SLS rocket, so if there are manufacturing issues, a science mission might be pushed aside. Finally, there is the possibility of further developmental delays—significant ground testing of SLS has yet to begin.

Another option is United Launch Alliance’s Delta IV Heavy rocket, which has an excellent safety record and has launched several high-profile missions for NASA. However, this rocket requires multiple gravity assists to push the Clipper into a Jupiter orbit, including a Venus flyby. This heating would add additional thermal constraints to the mission, and scientists would prefer to avoid this if at all possible.

A final possibility is SpaceX’s Falcon Heavy rocket, with a kick stage. This booster would take a little more than twice as long as the SLS rocket to get the Clipper payload to Jupiter, but it does not require a Venus flyby and therefore avoids those thermal issues. With a track record of three successful flights, the Falcon Heavy also avoids some of the development and manufacturing concerns raised by SLS vehicle. Finally, it offers the lowest cost of the three options.

The fact that Congress is requiring the use of SLS for a cost of $2 billion, a rocket that might not even be ready in time, when Europa Clipper could be launched on two other already operational rockets at about a tenth of the cost illustrates well the overall corruption and incompetence that permeates Congress. They really aren’t interested in the interests of the nation. They’d rather distribute money to big contractors and local interests, even if it costs the taxpayer billions and risks the mission’s success.

Virgin Orbit gets $9.5 million from UK space agency

The space agency of the United Kingdom yesterday awarded $9.5 million to the smallsat rocket company Virgin Orbit

ccording to the statement, the funds will be used “to develop launch operations support systems and manufacture them in the U.K.” in addition to conducting “mission planning, and to further ready the facility for satellite launches from Cornwall”.

This award is part of a larger funding package of $26 million (£20 million) from Cornwall Council and the Cornwall and Isles of Scilly Local Enterprise Partnership, while Virgin Orbit have also said they will contribute about $3.2 million (£2.5 million) to the Spaceport Cornwall project. The hope is that Cornwall could become a hub for European launches to space in the future.

Essentially this is an effort by the UK to bring Virgin Orbit’s launches to Cornwall spaceport. Why Virgin Orbit has got this money is puzzling however. Launched from a 747 which can take off from almost all airports, Virgin Orbit doesn’t necessarily need to launch from a spaceport. That fact is probably why the company got this “pay-off”, using somewhat more blunt words.

Sightseeing Central Butte on Mars

Central Butte in foothills of Mt Sharp

Overview showing perspective of panorama

Curiosity has now roved to the very foot of Central Butte, where it has been taking close-up and panorama images of the butte and its geological layers. The panorama above was created from three Curiosity navigation images taken on Sol 2577 (November 6, 2019), here, here, and here.

The overview on the right, based on Curiosity’s position about ten sols ago slightly farther from the butte, still indicates roughly with the yellow lines the area photographed in this panorama. The dotted red line indicates Curiosity’s initial planned route.

Following that route Curiosity will eventually climb up onto the plateau beyond this butte, approaching that higher terrain farther to the west. Once they do, however, they will no longer have access to the geological layers below the surface. Central Butte gives them a window into those layers, which is why they are going to spend some time at this location, first by taking a few sols looking at the butte at this point, then circling around to study its back side.

NASA rejects Blue Origin’s proposed SLS upper stage

After considering an alternative bid by Blue Origin to build a less expensive upper stage for NASA’s SLS rocket, replacing the stage that Boeing is building, NASA has decided to reject that bid and stick with Boeing.

NASA sets out three reasons for not opening the competition to Blue Origin. In the document, signed by various agency officials including the acting director for human spaceflight, Ken Bowersox, NASA says Blue Origin’s “alternate” stage cannot fly 10 tons of cargo along with the Orion spacecraft.

Moreover, NASA says, the total height of the SLS rocket’s core stage with Blue Origin’s upper stage exceeds the height of the Vertical Assembly Building’s door, resulting in “modifications to the VAB building height and substantial cost and schedule delays.” Finally, the agency says the BE-3U engine’s higher stage thrust would result in an increase to the end-of-life acceleration of the Orion spacecraft and a significant impact to the Orion solar array design.

The article notes that there were also significant political reasons as well that pushed NASA to favor Boeing.

The article also states that SLS’s cost per launch will be about $2 billion. Though I think that number is probably low because it does not include any of the $25 billion spent for development, it does compare badly with SpaceX’s Falcon Heavy, which costs about $100 million per launch.

NASA to fly more year-plus missions to ISS

Leaving Earth: In an effort to shift the research focus on ISS toward learning how to do interplanetary missions, NASA wants to fly more year-plus missions to the station.

Crewmembers usually spend about six months aboard the ISS before coming back down to Earth. But that’s far shorter than a Mars mission would be; the trip to the Red Planet takes eight to nine months one way with current propulsion technology. So, NASA wants more data about the effects of long-duration spaceflight on the physiological and psychological health of astronauts. (The ISS isn’t a perfect Mars analog in this respect, of course; it resides within Earth’s protective magnetosphere and is therefore exposed to less-damaging radiation than a Mars-bound craft would be.)

To date, the agency has launched just one yearlong ISS mission, sending Scott Kelly to live on the orbiting lab from March 2015 to March 2016. Russian cosmonaut Mikhail Korniyenko took part in this flight as well, spending 342 days in space, just like Kelly. NASA has also extended two other astronauts’ ISS stays into the “Mars transit” range: Peggy Whitson racked up 289 days of continuous flight in 2016 and 2017, and Christina Koch, who arrived on the orbiting lab in March, is now scheduled to come down in February 2020.

But these three data points aren’t enough, said [Julie Robinson, NASA’s chief scientist for the ISS Program],. “What we’re saying now is we want to really bump that up a notch and add 10 more subjects to that U.S. database,” she said.

The ISS Program has approved that plan, which NASA can start implementing once a private astronaut taxi is up and running, Robinson added.

NASA should have been doing this from the beginning, The Russians have always wanted to do longer missions, and have been frustrated by NASA’s resistance. That the agency is now pushing to focus ISS research on learning how to do interplanetary travel is wonderful news. It means that we will finally be using ISS properly.

Boeing proposes manned lunar lander that bypasses Gateway

Capitalism in space: Boeing today announced its bid to build a manned lunar lander for NASA’s Artemis program, with its lander launched to go directly to the Moon rather than stopping at the proposed Lunar Gateway lunar space station.

The company said its “Fewest Steps to the Moon” proposal, submitted for NASA’s Human Landing Services program, minimized the number of launches and other “mission critical events” needed to get astronauts to the surface of the moon. “Using the lift capability of NASA’s Space Launch System Block 1B, we have developed a ‘Fewest Steps to the Moon’ approach that minimizes mission complexity, while offering the safest and most direct path to the lunar surface,” Jim Chilton, senior vice president for space and launch at Boeing Defense, Space and Security, said in a company statement.

The two-stage launched would launch on the enhanced Block 1B version of the rocket, which uses the more powerful Exploration Upper Stage (EUS), and go into lunar orbit. It would either rendezvous with the lunar Gateway or directly with an Orion spacecraft, where astronauts would board it for a trip to the lunar surface. The lander is designed to be launched as a single unit, rather than in separate modules that would be aggregated at the Gateway. The lander also doesn’t require a separate transfer stage to maneuver from a near-rectilinear halo orbit to low lunar orbit, as some other designs have proposed.

This approach, the company said in a statement, reduces the number of mission critical events, such as launches and dockings, to as few as five. Alternative approaches, Boeing claims, require 11 or more such events. [emphasis mine]

Boeing is essentially proposing a plan that makes Gateway unnecessary, a bidding ploy that very well might work with the Trump administration, which has already reduced Gateway’s initial construction to speed up its attempt to get to the Moon by 2024.

More important, Boeing’s proposal makes it very clear how unnecessary Gateway is, and how that boondoggle actually slows down our effort to return to the Moon. This is great news, for several reasons. First it shows that Boeing, one of the old big contractors that historically has depended on government dollars, is now publicly stating that it is not in favor of Gateway. This in turn makes it more politically acceptable for politicians to take this position. Expect more public advocacy against building Gateway.

Second, it shows that Boeing is trying to sell SLS. It wants Congress to appropriate more launches, and by showing Congress a cheaper way to use it the company is hoping legislators will buy into their proposal. SLS might be an exceedingly expensive rocket, but Gateway only makes it worse. Boeing is showing the world that there is a better and cheaper way to do things.

This also suggests that Boeing is recognizing the competition coming from SpaceX and others that might kill SLS, and is now trying to make SLS more competitive. While I am not a fan of SLS, if this proposal indicates an effort by Boeing is finally to make SLS more efficient and affordable I can only celebrate. The rocket has capabilities that are unique, and if its cost can be reduced in any way that can only benefit the U.S. effort to compete in the exploration and settlement of the solar system.

TESS completes 1st survey of southern sky

The TESS science team today released its first full panorama of the southern sky, revealing everything the space telescope has imaged since launch in one image.

The glow of the Milky Way — our galaxy seen edgewise — arcs across a sea of stars in a new mosaic of the southern sky produced from a year of observations by NASA’s Transiting Exoplanet Survey Satellite (TESS). Constructed from 208 TESS images taken during the mission’s first year of science operations, completed on July 18, the southern panorama reveals both the beauty of the cosmic landscape and the reach of TESS’s cameras. “Analysis of TESS data focuses on individual stars and planets one at a time, but I wanted to step back and highlight everything at once, really emphasizing the spectacular view TESS gives us of the entire sky,” said Ethan Kruse, a NASA Postdoctoral Program Fellow who assembled the mosaic at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Within this scene, TESS has discovered 29 exoplanets, or worlds beyond our solar system, and more than 1,000 candidate planets astronomers are now investigating.

A reduced version of this image wouldn’t show anyone its beauty or significance. I have embedded below the fold the short video at the link which shows it quite nicely. The video also summarized the mission quite well.
