India successfully launches Chandrayaan-2

8:24 am

The new colonial movement: India yesterday successfully launched its lunar orbiter/lander/rover Chandrayaan-2 into orbit.

India’s Geosynchronous Satellite Launch Vehicle GSLV MkIII-M1, successfully launched the 3840 kg Chandrayaan-2 spacecraft into an earth orbit today (July 22, 2019). The spacecraft is now revolving round the earth with a perigee (nearest point to Earth) of 169.7 km and an apogee (farthest point to Earth) of 45,475 km. Today’s flight marks the first operational flight of the GSLV Mk III.

They will slowly raise the spacecraft’s apogee over the next two months to bring it into the Moon’s gravitational sphere of influence, when they will begin lowering the orbit leading to a separation of the lander/rover for a September 7 landing near the Moon’s south pole.

This was the third launch of the upgraded GSLV Mark III. With this launch India now has an operational rocket it can use to launch its astronauts into space in 2022.

The leaders in the 2019 launch race:

9 China
9 Russia
8 SpaceX
5 Europe (Arianespace)
4 India

The U.S. continues to lead in the national rankings, 14 to 9.

July 20, 1969: “We came in peace for all mankind.”

6:01 pm

An evening pause: In honor of the fiftieth anniversary.

The astronauts plant the American flag, after they had unveiled a plaque on the lunar module with the words, “We came in peace for all mankind.”

This was an American achievement, accomplished because our free and competitive society gave us the resources and trained talent to make it happen. We did it for all mankind, in good will, but we did it, no one else.

It is time that we as well as everyone else do it again.

The Untouched Moon

6:01 pm

Montes Carpatus
Click for full image.

In celebration of Apollo 11: Continuing the theme of yesterday’s cool image, where I noted how little of the Moon we have really seen, today’s cool image gives us a breath-taking glimpse of one such untouched region, the Montes Carpatus region.

The photograph to the right, reduced to post here, was released by the Lunar Reconnaissance Orbiter (LRO) science team in March 2018. From the release:

Volcanic rocks are our best window to the deep interior of the Moon, and the Montes Carpatus has no shortage of volcanic landforms: lava flows, pyroclatic deposits, rilles, and more! Lavas are formed as the mantle begins to melt, so by sampling volcanic rocks of various ages from regions across the Moon scientists can reconstruct the range of compositions and processes over time. The Montes Carpatus formed as a result of the giant impact that formed the mighty Imbrium basin, the mountains are actually the raised rim of the basin.

Today is the 50th anniversary of the Apollo 11 landing. If you had told anyone involved in that mission that fifty years later no significant further manned exploration of the Moon had yet occurred, they would have scoffed.

It is a terrible condemnation of my generation, the generation that followed Apollo 11, that we did nothing grand like this. I challenge the generations today to reach higher, and do better.

July 20, 1969: “One small step…”

6:01 pm

An evening pause: In honor of the fiftieth anniversary.

Neil Armstrong takes the first steps on the Moon. Note his focus is almost entirely on describing what he sees and experiences. He is doing this for two reasons, first to provide knowledge of the Moon to the world, and second to provide engineers as much information as possible for future missions.

This focus explains why the first thing he does is to get a contingency rock sample, just in case they need to leave the Moon quickly.

Note also that when Buzz Aldrin joins Armstrong on the surface, he is as professional and calm, proving that the way he has been portrayed by some recent movies as as undisciplined jerk is simply a slander. He would not have been picked for this mission if he really behaved that way.

He wanted to be the first, and lobbied to get that chance. After the decision was made he got down to work to make the mission a success.

For a different view of these same events, watch this video.

July 20, 1969: “The Eagle has landed”

7:01 pm

An evening pause: In honor of the fiftieth anniversary.

Note the calm tone in all the voices, even when something is not quite right. To do really great things, one must not let one’s emotions run the show. You need to be cool-headed and focused on the task at at hand. If only today’s adult generation, especially in the world of politics, would do the same.

Just before Armstrong brings Eagle down, you will hear a voice say “60 seconds,” then “30 seconds.” That is mission control telling him how much time they estimate he has before he runs out of fuel.

Below the fold is the same last few minutes of the landing, produced by the Lunar Reconnaissance Orbiter (LRO) science team using its high resolution images to recreate a simulation of what Armstrong saw in his window. Remember, the view in the original 16mm film was out Aldrin’s window.

The Taurus-Littrow valley

6:01 pm

Taurus-Littrow Valley
Click for full image.

It might not be Apollo 11, but during this 50th anniversary week of that mission, why not look at where the last Apollo 17 crew landed, in the middle of the Taurus-Littrow valley, as shown on the right in a Lunar Reconnaissance Orbiter (LR) image released by the LRO science team in 2018.

The image illustrates how ambitious NASA had become by this last Apollo mission. The Apollo 11 site was chosen because it was flat with as few risks as possible. By Apollo 17, the Apollo engineers and astronauts were quite willing to drop the LM down into this valley between gigantic mountains. Granted, the valley was more than 400 miles wide, but considering the risks of every Apollo flight, the choice was daring to say the least.

Taurus-Littrow also has a cluster of craters believed to have been formed by material flung out from the formation of 86-kilometer-wide Tycho crater about 100 million years ago. Tycho is 2250 kilometers from Taurus-Littrow, but the impact that formed it was violent enough that it cast material far across the Moon.

Nor is this location the most spectacular on the Moon. In fact, considering that all the manned and unmanned missions in total have probably covered less ground than a New York cab driver does in a single day, we have seen almost nothing there.

Eagle undocks, Apollo 11, July 20, 1969

6:01 pm

An evening pause: In honor of the fiftieth anniversary of Apollo 11, today’s evening pause shows the moment when the lunar module Eagle undocked from the command module Columbia. Though this video includes communications with mission control at the start, the actual undocking occurred on the back side of the moon, when the astronauts were out of touch with the Earth.

Near the end of the video, after they have reacquired communications with the ground, you can hear a recitation of a long string of numbers. This is mission control providing the astronauts the numbers that had to be uploaded into their onboard computer so that it could correctly fire the spacecraft engines at the right time and for the right duration.

A wave on the Moon

3:01 pm

A lunar ejector blanket

Continuing this week’s celebration of the 50th anniversary of the Apollo 11 mission means we get to look at another cool image from the Moon. The photograph on the right, reduced to post here, was released by the Lunar Reconnaissance Orbiter (LRO) science team in 2016.

What are we looking at? At first glance it looks like a black & white photograph of The Wave in northern Arizona. What it is instead is the pattern of ejecta laid down across the surrounding terrain immediately after the impact that created relatively fresh Chaplygin Crater. From the website:

The delicate patterns of flow across, over, and down local topography clearly show that ejecta traveled as a ground hugging flow for great distances, rather than simply being tossed out on a ballistic trajectory. Very near the rim lies a dark, lacy, discontinuous crust of now frozen impact melt. Clearly this dark material is on top of the bright material so it was the very last material ejected from the crater.

Below the fold is a wider shot of the entire crater and its surrounding terrain, with the rectangle indicating the region covered by the close-up above The dark crust near the rim mentioned in the quote can clearly be seen.

India reschedules Chandrayaan-2 launch

8:36 am

The new colonial movement: India’s space agency ISRO have rescheduled the launch of Chandrayaan-2 lunar orbiter/lander/rover now for July 22, 2019.

The new launch date apparently requires a very short launch window.

July 15 had offered the most comfortable launch window of 10 minutes for the Mission. But Isro has managed to successfully launch several satellites within one-minute windows in the past. However, delaying beyond July 31 could have potentially reduced the Orbiter’s life around the Moon.

Weird lunar crater

2:58 pm

Concentric crater in Apollo Basin on the Moon

In celebration of the 50th anniversary of the Apollo 11 mission, it is time for another cool image from the Moon. The photograph on the right, reduced to post here, was taken by Lunar Reconnaissance Orbiter (LRO) in 2013. It shows a weird crater with concentric features that is found within Apollo Basin, a large 334-mile-wide double-ringed impact feature in the southern hemisphere of the Moon’s far side.

Concentric craters have an inner rim whose formation mechanism is not yet entirely understood, but the concentric mounds may indicate that there is a discontinuity, such as layers with different strengths, in the subsurface excavated by the impact.

Or to put it more bluntly, they really have no idea why this crater ended up looking as it does.

Apollo 11 First Stage liftoff

6:01 pm

An evening pause: This was originally posted as an evening pause in 2016. I think that today, the fiftieth anniversary of the launch of Apollo 11, it is appropriate to repost it. As I wrote then,

Though the video is more than 8 minutes long, the actual events recorded lasted only about 30 seconds, beginning 5 seconds before T minus 0.

What struck me most as I watched this was the incredible amount of complex engineering that went into every single small detail of the rocket and the launch tower and launchpad. We tend to take for granted the difficulty of rocket engineering. This video will make you appreciate it again.

It is also mesmerizing. A lot happens in a very short period of time.

Tonight’s evening pause begins eight days of pauses dedicated to celebrating, and reliving, the Apollo 11 mission. To the Moon!

A lunar crater wall two miles high

11:06 am

Giordano Bruno crater

Cool image time! Considering this week is the 50th anniversary of the Apollo 11 lunar landing, it seems appropriate to show some cool images from the Moon.

Today the Lunar Reconnaissance Orbiter (LRO) science team released a spectacular oblique image of Giordano Bruno crater. The image on the right is cropped and very significantly reduced to post here. It looks across the crater, with the near rim across the bottom of the picture and the wall of the far rim filling the photograph’s top half.

That wall is what makes this image cool. It is a cliff about 10,000 feet high, equaling almost two miles. Moreover, at its base is a now-solidified melt pool left over from the impact that made the crater.

Faster than a speeding bullet – or rather ten times faster than a speeding bullet – is a good starting point in terms of grasping the energy released in a typical impact event. That is, for a bullet approaching 2 kilometers in diameter! The pressure and heat that were released during the collision not only excavated a hole much larger than the impactor but also melted a tremendous amount the target rock. Melt was sprayed and sloshed on the forming crater walls where much of it flowed back, seeking the lowest point in the impact crater. From the LROC vantage point you can follow the path taken by impact melt as it flowed across the irregular floor, ponding in closed depressions, and some of it ultimately reaching the lowest point.

Below the fold is a much higher resolution section of this photograph, focused on the crater wall and the melt pool. I have still been forced to reduce the resolution somewhat to post it here. Along that cliff wall can be seen partial avalanches (the dark splotch near the center) as well boulder tracks with the boulders (probably larger than most houses) still visible as white spots at the wall’s base.

The scale here is difficult to imagine. This cliff wall is three times as high as The Abyss, the steepest single drop viewpoint along the south rim of the Grand Canyon.

Chandrayaan-2 launch scrub caused by leak in helium bottle

8:50 am

Engineers today announced that the July 14 scrub of India’s Chandrayaan-2 lunar orbiter/lander/rover was caused by a leak in a helium bottle in the GSLV rocket.

“The good news is that we can fix the leak without dismantling the rocket, since there is an access door to the gas bottle which is atop the oxygen tank,” a senior scientist told TOI. “The bad news is that unless we ascertain the reason for the leak, there is a probability of the problem recurring.” Not having to dismantle means Chandrayaan-2 may be able to fly before the end of the July launch window, but a final failure analysis will be available only in a day or two.

Sources told TOI that the leak wasn’t serious enough to impair the flight, but Isro decided to apply “abundant caution,” given the importance of the Rs 978-crore project that would make India only the fourth country – after the US, Russia and China – to land a craft on the lunar surface.

I am willing to bet that if their investigation does not pinpoint the cause of the leak in the next few days, they will stand down from the July launch window. This mission, as well as proving the reliability of their GSLV rocket, are both too important to risk on an unknown and unsolved engineering issue.

Beresheet design adopted by Firefly & Israeli private partnership

9:17 am

Capitalism in space: The American smallsat launch company Firefly Aerospace announced today that they will be partnering with a private Israeli company to use the design of Beresheet to build their own lunar lander for NASA.

Firefly Aerospace announced that it is partnering with Israel Aerospace Industries (IAI) to create a new lunar vehicle based on the crashed spacecraft’s blueprints. Firefly says this lander will build upon “lessons learned” from the accident to ensure that the new lander does not meet the same fate.

…If Firefly does mount a lunar mission, the company’s lander, called Genesis, will leverage much of the Beresheet design as well as the IAI team’s flight experience. “Firefly Aerospace is excited to partner with Israel Aerospace Industries to provide the only NASA CLPS program flight-proven lander design,” Shea Ferring, Firefly’s vice president of mission assurance, said in a statement. The name of the lander is also a nod to Beresheet, which means “Genesis” in Hebrew.

It appears that a group of engineers from the non-profit SpaceIL, that built Beresheet, have teamed up to form their own company. It also appears that they have some rights to the spacecraft’s design, and could take them with them.

Firefly is competing for a NASA contract to land on the Moon. This deal strengthens their bid considerably.

Chang’e-4/Yutu-2 return to dormant mode for lunar night

8:59 am

According to one story in the Chinese press today, the science teams running Chang’e-4 and Yutu-2 on the far side of the Moon have now put both into dormant mode for the coming lunar night after completing their seventh lunar day.

What is intriguing about this short story is that while to lauds the work done by Chang’e-4 during that seventh lunar day, it says nothing about Yutu-2. Early comparable reports would have at least told us how far the rover moved during the lunar day. This time they say nothing at all about Yutu-2, other than it has been placed in dormant mode.

It could very well be that they had a problem with the rover. Sadly, China is not an open society. We can only wait for them to tell us.

Private lunar lander company files for bankruptcy

8:52 am

Capitalism in space: Former Google Lunar X-Prize competitor Part Time Scientists has now filed for bankruptcy.

The company, with about 60 employees, has emphasized a number of partnerships with major corporations, such as Audi, Vodafone and Red Bull Media House, a subsidiary of beverage company Red Bull. The company is also teamed with ArianeGroup to study development of a lunar lander mission for ESA.

PTScientists, though, had suffered delays in the development of its lunar lander. The company said last November its lander could launch as soon as late 2019, a date it revised in January to no earlier than the first quarter of 2020. However, at a conference in early June, a company official said that lander mission would now launch no earlier than the second half of 2021 as it continues to work on the lander’s design.

It appears to me that they simply were never able to raise the capital necessary to build their lander, despite these partnership deals.

The travels of China’s Yutu-2 rover on the Moon

9:34 am

Yutu-2 and Chang'e-4
Click for full image.

The Lunar Reconnaissance Orbiter (LRO) science team today released images that track the travels of China’s lunar rover Yutu-2 from its landing on January 30, 2019 through June 3, covering the rover’s first six lunar days on the Moon.

The image to the right, cropped, reduced, and annotated to post here, shows the relative positions of both spacecraft as of June 3, 2019. In the release they also included a gif movie showing the progression of Yutu-2’s movements since landing.

Once a month, LRO passes over the Chang’e 4 landing site, allowing LROC to capture a new image. LROC has now imaged the site five times (since the landing) and observed Yutu-2 to have traveled a total of 186 meters (distance measured using the rover tracks). If you squint, portions of the rover tracks are visible as a dark path in the images from April, May, and possibly June.

table of Yutu-2's movements through June 2019

The LRO release also included a table showing the distance Yutu-2 has traveled with each lunar day, shown on the right. The table does not include the 23 meters (75 feet) the rover traveled on its sixth lunar day. My estimate yesterday that Yutu-2 was traveling an average of about a 100 feet per day, with the distances per day shrinking with time, seems largely correct. During the rover’s fourth and fifth lunar days it moved very little, either because they had found something very interesting they wanted to inspect more closely, or they were moving more cautiously as the rover’s life extended past its planned lifespan of three lunar days.

On the sixth day however they increased their travels again, suggesting that either they had finished the observations at the previous location, or they had gained more confidence in the rover’s staying power.

Chang’e-4 and Yutu-2 awake for 7th lunar day

8:42 am

The new colonial movement: Chinese engineers have awakened both the Chang’e-4 lander and the Yutu-2 rover to begin work on their seventh lunar day on the Moon’s far side.

The text of this Chinese news report is almost identical to the text in the news report a month ago, when both spacecraft were awakened for the sixth lunar day. And as before, it tells us little.

What today’s story reveals is that Yutu-2 traveled only about 75 feet during the sixth lunar day. With an overall odometer reading of 695 feet, it appears it is averaging about 100 feet per lunar day, with the per day number dropping with time. Either the science team is becoming cautious, or they have had unstated issues that have slowed them down.

Still, the rover’s nominal mission was only three lunar days, so it is survived more than twice as long as designed.

Bridenstine: Artemis to cost $4-$6 billion per year

8:30 am

According to several reports this past weekend, NASA administrator Jim Bridenstine is now estimating the cost for the Trump administration’s Artemis lunar program at $20 to $30 billion, or $4 to $6 billion per year.

This has not been officially confirmed. Either way, I am not sure how Bridenstine will get this approved in the House, where the Democrats now have a policy to oppose any Trump proposal 100%. And if it doesn’t get approved, SLS will die after its second launch, as the bulk of this budget is to pay for its future flights to the Moon.

If a lower figure gets approved, that might force NASA to buy private rockets almost exclusively to get back to the Moon, rather than the mix of private and SLS as now proposed.

NASA selects three companies to provide lunar landers for its science instruments

10:43 am

Captalism in space: NASA today announced the selection of three new companies to provide the agency lunar landers on which to fly its science instruments to the Moon.

The companies chosen:

  • Astrobotic of Pittsburgh has been awarded $79.5 million and has proposed to fly as many as 14 payloads to Lacus Mortis, a large crater on the near side of the Moon, by July 2021.
  • Intuitive Machines of Houston has been awarded $77 million. The company has proposed to fly as many as five payloads to Oceanus Procellarum, a scientifically intriguing dark spot on the Moon, by July 2021.
  • Orbit Beyond of Edison, New Jersey, has been awarded $97 million and has proposed to fly as many as four payloads to Mare Imbrium, a lava plain in one of the Moon’s craters, by September 2020.

If successful as awarded, the cost for these spacecraft will be minuscule compared to what NASA normally spends for its own planetary probes.

These contract awards are puzzling however in one way. All three companies are relatively unknown. None competed in the Google Lunar X-Prize, as did the American company Moon Express, which at one time was thought to be very close to launching. That Moon Express is not one of the winners here is mysterious. The only explanation I can come up with is the lawsuit that Intuitive Machines won from Moon Express in January 2018. Maybe that suit killed Moon Express, and made Intuitive Machines the winner today.

Chang’e-4 and Yutu-2 wake up for sixth lunar day

8:29 am

China’s Chang’e-4 lander and Yutu-2 rover have been reactivated this week to begin observations during their sixth lunar day on the far side of the Moon.

According to the Chinese news source,

For the sixth lunar day, the lander’s neutron radiation detector and low-frequency radio detector will be restarted to conduct scientific tasks including particle radiation observation and low-frequency radio astronomical observation.

The rover’s panoramic camera, detection radar, infrared imaging spectrometer and neutral atom detector will be restarted during the sixth lunar day.

That’s about all we know. They have not released much information about the rover’s travels, nor have they released any detailed information about the data they have obtained.

Future lunar colonies at Shackleton Crater at the Moon’s south pole

9:52 am

The rim of Shackleton Crater
Click for full image.

The Lunar Reconnaissance Orbiter (LRO) science team has released a new image of the rim of Shackleton Crater, reduced slightly in resolution to post here on the right. The Moon’s south pole is located on the crater’s rim near the top right of this image. As they note at the link, the interior of Shackleton never gets any sunlight, making it what scientists call a Permanently Shadowed Region (PSR), while a ridgeline running south to de Gerlache Crater gets sunlight 90% of the time.

An elevated ridge runs roughly between Shackleton and de Gerlache craters, and the relatively high elevation of this landscape means that some portions are illuminated up to 90% of the time, but nowhere is permanently illuminated. Future explorers could take advantage of this persistent illumination by setting up solar panels in several closely spaced locations providing nearly constant solar generated electricity.

The proximity to Permanently Shadowed Regions in and around Shackleton crater adds scientific value to this destination, as PSRs are often home to compounds such as water ice that are not found elsewhere on the Moon, but which contain clues to the history of of inner Solar System water and other volatile elements. A nearby, ready source of water-ice would also be of benefit to human surface activities, either as a consumable (air or water) or as spacecraft fuel.

Below is a more detailed map they provide showing this area, with the permanently shadowed regions shaded in blue. The green dot indicates the location of the south pole. The green arrows indicate regions in sunlight in the full image.

The region around Shackleton

Sadly, I expect we are looking at the locations of future Chinese and Indian lunar bases. Though the U.S. has done all the proper legwork to find out the exact locations to build a lunar base at Shackleton, our government has decided we will instead twiddle our thumbs in lunar orbit while other countries use our legwork to land and establish bases on the Moon itself.

New LRO pictures showing Beresheet impact site

3:18 pm

The Lunar Reconnaissance Orbiter (LRO) science team yesterday released an image showing the impact site where the privately-built Israeli lunar lander Beresheet crashed onto the surface of the Moon on April 11, 2019.

“The cameras captured a dark smudge, about 10 meters wide, that indicates the point of impact,” said NASA. “The dark tone suggests a surface roughened by the hard landing, which is less reflective than a clean, smooth surface.”

The image released does not see the spacecraft but the surface evidence that an impact took place. Higher resolution images will be required to spot any surface wreckage.

Trump seeks $1.6 billion more for NASA, cuts money to Gateway

7:40 pm

The Trump administration, in order to support its desire to accomplish a lunar landing by 2024, is requesting a $1.6 billion increase in NASA’s budget for fiscal year 2020. The key detail however is this:

NASA shortly thereafter published a summary of its budget amendment, which calls for nearly $1.9 billion in new funding for developing lunar landers and accelerating work on the Space Launch System and Orion. It would also go towards exploration technology development and additional science missions to the moon. That increase would be offset by cutting funding for the lunar Gateway by $321 million, reflecting the agency’s plan for only a “minimal” Gateway needed to support a 2024 landing.

In other words, in total Trump wants $1.6 billion more. The good news: He is de-emphasizing Gateway in his future plans. This might even lead to its cancellation as a project.

The bad news? He is pumping more money into SLS/Orion. However, this might not be that bad, when one considers how our bankrupt Washington government functions. Trump doesn’t have the political backing to cut SLS/Orion outright. Instead this proposal is that project’s Hail Mary pass for a touchdown. While private efforts continue to mature to develop cheaper rockets and manned capsules, SLS/Orion will have this one last chance to finally prove itself. If it finds it can’t get it done, and those private options show that they can, then Trump might finally be able to harness the political will in our dumb Congress to dump SLS/Orion.

And if SLS/Orion does succeed? The victory will likely still be a Pyrrhic one. SLS/Orion will still be too expensive and too slow to do much else but a single lunar landing, a stunt much like Apollo, with far less long term possibilities. Meanwhile, those private efforts will continue to develop. By 2024 a switch by NASA to private enterprise and competition will still make sense anyway, even if SLS/Orion gives the nation a spectacular lunar landing.

This action indicates that the Trump administration is paying attention to these matters. They are creating a situation that will put them in a strong negotiating position to get what they want, for the nation. One way or the other, we will be heading back to the Moon.

One minor detail: NASA has chosen “Artemis” as the name for its project to land on the Moon by 2020.

Bridenstine also … announce[d] that this 2024 lunar landing mission will be named Artemis, after the sister of Apollo and the Greek goddess of the moon. “I think it is very beautiful that, 50 years after Apollo, the Artemis program will carry the next man and the first woman to the moon.”

No one should be fooled by this. Apollo was a full program, with a well-thought slate of missions designed to get us to the Moon quickly. This SLS/Orion project is still an off the cuff mishmash, with only two or three flights at most, and without much of a plan behind those flights. It has been and continues to be an improvised mess.

Yutu-2 travels more than 600 feet during its fifth lunar day on the Moon

8:35 am

The Chinese press today revealed that during its fifth lunar day on the Moon’s far side China’s lunar rover Yutu-2 traveled about 623 feet.

Where exactly it went, and what it learned, they did not reveal. We will have to wait for Lunar Reconnaissance Orbiter images to learn the rover’s route.

They have now put both Yutu-2 and the lander Chang’e-4 into sleep mode for the long lunar night.

India sets Chandrayaan-2 launch and lunar landing dates

9:30 am

India’s space agency ISRO has announced that the launch of Chandrayaan-2 will take place in a window from July 9 to July 16, and the landing of its Vikram rover will occur on September 6.

The delay in the landing is probably to allow Chandrayaan-2 to get to the Moon, then review the landing site to make sure it is acceptable.

This is not the first time they have announced a launch schedule for Chandrayaan-2 and then delayed it. This time however I think the dates are firm.

The battle over Trump’s Moon effort exposes Washington’s power-hungry bureaucracy

1:32 pm

This analysis by Eric Berger at Ars Technica of the political situation surrounding SLS, Orion, Gateway, and the Trump administration’s desire to quickly get back to the Moon is quite cogent and worth reading in full. It suggests that it will be very difficult for Trump to get his lunar landing, for several reasons. First, the Democrats in the House will likely not fund it. Second, because to get it done by 2024 will likely require switching to private rockets, and that action will be opposed by Senator Richard Shelby (R-Alabama). And third because there are factions in the NASA bureaucracy that are in love with SLS and Gateway and will work to save it.

This quote is most telling:

At NASA headquarters, [human spaceflight chief Bill] Gerstenmaier and this team that plays a central role in developing policy for the space agency are likely content to play a waiting game. Without an increased budget he can continue to spend money on developing the SLS rocket for some future launch date and begin procuring elements of the Lunar Gateway. He can make some small investments in a lunar lander but doesn’t have to commit to its development before the end of next year, which may bring a new president and new priorities.

In other words, Bill Gerstenmaier, an unelected bureaucrat at NASA, has more power to determine U.S. space policy than elected lawmakers.

I ask, how does Gerstenmaier have the right to “develop policy for the space agency?” What legislative authority gives him the right to “play a waiting game” while continuing to “spend money on developing the SLS rocket… and procuring elements of Lunar Gateway?” These are policy decisions that belong solely to Congress and the President, not some hired government bureaucrat.

In a sense this story is only another reflection of the entire Russian collusion scandal. Hired government officials with no legal authority decide that they really know best, and this hubris allows them to supplant the decisions of lawmakers, and even attempt to overthrow them if necessary.

I reluctantly predicted this behavior back in June 2016 when I visited Washington and wrote this essay: The think tank culture of Washington:

What will this elite community do should Trump win the presidency and start demanding that they do things differently? Will they recognize that we are a democracy and work with him, the elected choice of the American people, or will they resist because he isn’t the politician they wanted and wants to institute policies they disagree with?

…I fear that the culture of Washington is becoming increasingly hostile to and insulated against the choices of the American electorate. I fear that they will one day soon decide to team up with the politicians they like to use the concentrated power we have given them in Washington to reject those choices, even to the extent of tossing out the Constitution and the democratic legal system that made the United States once the freest and wealthiest nation in the history of the human race.

I hope I am wrong. I pray that I am wrong. I think we might very well find out in the coming year.

Sadly, what we have learned in the past three years is that this Washington think tank culture is quite willing to overthrow the Constitution and the law, to get what they want. The situation at NASA only gives us another example of this terrible reality.

Lunar eclipse meteorite hit the Moon at almost 38,000 mph

10:33 am

By analyzing the data obtained of the meteorite impact that hit the Moon during the January 21 lunar eclipse, astronomers now estimate it crashed into the surface at almost 38,000 miles per hour and would have produced a crater about 50 feet across.

They also estimate that the meteorite itself had a mass of about 100 pounds with a diameter of between one to two feet.

The new crater itself has not yet been spotted, and probably can only be photographed with the high resolution camera on Lunar Reconnaissance Orbiter (LRO). I expect the LRO science team has already scheduled observations for this location. It will be interesting to see if the actual crater corresponds to the estimates of these astronomers.
