Curiosity captures a dust devil

11:33 am

During its recent and last several-week-long drilling effort in the clay unit in Gale Crater, the rover Curiosity was also able to luckily capture the passing of a nearby dust devil.

It’s almost summer in Gale crater, which puts us in a period of strong surface heating that lasts from early spring through mid-summer. Stronger surface heating tends to produce stronger convection and convective vortices, which consist of fast winds whipping around low pressure cores. If those vortices are strong enough, they can raise dust from the surface and become visible as “dust devils” that we can image with our cameras. The animated GIF shows a dust devil movie we took with Navcam on Sol 2847, covering a period of about five minutes. We often have to process these images, by enhancing what’s changed between them, before dust devils clearly show up. But this dust devil was so impressive that – if you look closely! – you can just see it moving to the right, at the border between the darker and lighter slopes, even in the raw images.

I have embedded the movie below the fold. The dust devil looks like a ghostly white tower moving from the left to the right just above the darkest band of landscape cutting across the middle of the image.

SpaceX wins launch contract for unmanned lunar lander

11:24 am

Capitalism in space: Masten Space Systems has awarded SpaceX the launch contract for its unmanned lunar lander, being built to carry nine NASA science payloads to the south pole of the Moon.

Launch is tentatively scheduled for late ’22.

NASA will be an anchor customer for the mission but Masten intends to sign up others. “There is a tremendous amount of interest,” he said, including from both the public and private sector, although he didn’t mention any specific potential customers.

Mahoney said the level of customer interest soared after Masten won the CLPS award and had a firm schedule for the mission. “Once the CLPS award was made and we crossed from speculative to having a schedule, the tenor and tone of our conversations have changed dramatically.”

The limiting factor for the lander mission has not been the amount of mass available for payloads, he said, but instead positions on the lander that have views of the surface desired by payloads. “There’s a game of positioning among the various instruments so that they can get the view angles that they need and not interfere,” he said.

However, he said the company isn’t considering major changes in the lander’s design to accommodate payloads. “The design principle is the ‘pickup truck’ that can haul a bunch of different things,” he said. “We’re trying to escape the completely unique, bespoke system that does one job and one mission really well.”

I guarantee that at least one university student-built payload will end up on the lander.

FCC approves expansion of OneWeb constellation to 2,000 satellites

11:19 am

Capitalism in space: The FCC has approved the request by the satellite company OneWeb to increase the size of its satellite constellation from 720 to 2,000 satellites, at 50% of which must be launched by August ’26.

The company, now exiting bankruptcy with its purchase by a partnership of the UK government and an Indian-based communications company, appears gearing up to resume launches.

The FCC’s approval was partly because it would “increase competition for broadband services.” Under the Trump administration the goal is to encourage as many private space companies as possible, to promote innovation and the lowering of costs to the consumer. This decision continues that policy.

NASA’s first Orbiting Geophysical Observatory to burn up in atmosphere

11:11 am

The first of six Orbiting Geophysical Observatories, dubbed OGO-1, is set to to burn up in the atmosphere sometime in the next week.

Launched September 5, 1964, OGO-1 operated until 1969. It along with the five later OGO satellites were designed to study the Earth’s magnetic field as well as the Van Allen Belts across a solar minimum and maximum. Together they proved the magnetosphere was homogeneous, somewhat the same wherever data was obtained.

As the first such observatory, the spacecraft was also a technology test. Thus, the failure of its attitude control system, preventing about half its instruments from gathering data, was not really a failure. It laid the groundwork for all such research satellites to follow over the next half century.

Five American launches in two days!

9:51 am

Capitalism in space: Though the first launches in the string of four American launches that was initially scheduled to begin two days ago and continue through the weekend was delayed because of weather and then technical issues, all these delays have done is pack those scheduled launches into a shorter time period, with the addition of a fifth launch!

If all goes as scheduled (hardly guaranteed), we will see five launches from three spaceports and four private companies in less than two days. The schedule, as of this moment:

August 29th at 2:04 am (Eastern): ULA’s Delta 4 Heavy to launch a military reconnaissance satellite from Cape Canaveral. The company’s webcast of the launch can be seen here.

August 29th at 11:05 pm (Eastern): Rocket Lab’s Electron rocket will launch a commercial radar satellite from New Zealand. The launch can be watched at the company’s live stream channel.

August 30th at 10:08 am (Eastern): SpaceX’s Falcon 9 will launch more of its Starlink satellites from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 7:19 pm (Eastern): SpaceX’s Falcon 9 will launch an Argentinian Earth observation satellite from Cape Canaveral. All SpaceX launches are live streamed from SpaceX’s website, though the links are not yet up.

August 30th at 10:00 pm (Eastern): Astra will attempt the first orbital test launch of its privately built rocket from Kodiak, Alaska. They will not be live streaming their launch, but will provide updates at their Twitter feed.

All times and dates list only the beginning of the launch windows, which means they might launch, but not exactly at the times listed.

Also, SpaceX is aiming to do its second Starship test hop this weekend, the first for its sixth prototype.

Democratic voters swamp CSPAN to say they are switching to Trump

9:19 am

CSPAN's new call lines, eliminating party affiliation

Is this a sign of hope? So many callers on CSPAN’s Democratic Party call line were calling to announce they were either switching to Trump or becoming Republicans after watching the two conventions these past two weeks that CSPAN changed the call lines from “Democrat” and “Republican” to “Support Biden” and “Support Trump.”

I always like to say “It’s the audience that counts.” In this case the audience appears to be making its preference loud and clear, which is to me is truly a sign of hope. Conservatives and supporters of liberty and the rule of law might cheer the speeches and presentations at the Republican convention, but it is how the unaffiliated general public reacts that matters. And at least from this one data point, it appears they are trending to the Republicans.

UPDATE: I stupidly listed the channel incorrectly as CNN in my initial post. This is now corrected.

More glaciers and eroding gullies on Mars

2:51 pm

Crater with gullies and glacial fill
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, shows the interior south-facing rim of a small crater in the southern cratered highlands of Mars. Taken on May 30, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), the image release is merely labeled “Gullied Slope”. The photo was taken as part of regular monitoring of these gullies since 2011 to see if they change from season to season. The 2011 image was captioned by planetary scientist Alfred McEwen, who wrote the following about the gullies:

These are erosional features with depositional fans. Some of the gully fans have a bluish color: these are probably quite recent deposits, less than a few tens of years old.

Since they were considered so very young, it makes great sense to look at them frequently. In making a quick comparison between the 2011 and 2020 images however I could not spot any changes, but that might be because the versions I downloaded are not at the fullest resolution.

This crater, at 39 degrees south latitude, is also worthwhile because its floor appears covered with glacial material, what scientists have dubbed concentric crater fill. As McEwen noted in his 2011 caption,

On the floor of the crater (bottom of this image) are ridges that likely formed from the flow of ice, perhaps a few million years ago.

Those glaciers, generally protected by thin layers of dust and debris, are considered inactive at this time in Martian geological history. The many ridges however hint at the many many cycles in the Martian climate, fluctuating between periods when these mid-latitude glaciers were growing while the polar ice caps were shrinking, and periods when the mid-latitude glaciers were shrinking while the polar ice caps were growing.

It is the PARTY of Biden that must lose big in November

1:03 pm

Modern Fifth Avenue in New York
Today’s bankrupt New York,
a typical Democrat-run city

With the upcoming November presidential election, only two months away, the major focus continues to be on Trump and Biden. Who should win? Who is better? Do we want four more years of Trump or another four years of a Obama-type rule?

My readers will know immediately where I stand. Biden would be major disaster for the country, especially because it appears he is declining both physically and mentally and seems owned by the most radical leftist elements of his Democratic Party.

This essay, however, is a call for voters to not just vote for Trump. It is a desperate call for voters from both parties and from all ethnic, religious, and racial cohorts to vote for Republicans in every election and at every level of government. Biden is only the figurehead. It is the body of the now very corrupt, anti-American, and radical Democratic Party that must be killed, thoroughly and at all levels, including the House, the Senate, and in every state, city, and local council election.

The riots and looting and the almost willing endorsement and support given to those riots and looting by local Democratic mayors and councils and state governors demonstrates their incompetence to hold office. For the United States to survive as a nation ruled by law that also supports the freedom of its citizens, voters must reject them, unequivocally.

Hubble maps giant gas halo around Andromeda

11:38 am

Astronomers using the Hubble Space Telescope’s ability to observe in ultraviolet wavelengths have now mapped the giant halo of gas that surrounds the Andromeda galaxy 2.5 million light years away.

The work found that the halo appears to have both an inner and outer shell.

“We find the inner shell that extends to about a half million light-years is far more complex and dynamic,” explained study leader Nicolas Lehner of the University of Notre Dame in Indiana. “The outer shell is smoother and hotter. This difference is a likely result from the impact of supernova activity in the galaxy’s disk more directly affecting the inner halo.”

A signature of this activity is the team’s discovery of a large amount of heavy elements in the gaseous halo of Andromeda. Heavier elements are cooked up in the interiors of stars and then ejected into space—sometimes violently as a star dies. The halo is then contaminated with this material from stellar explosions.

The Andromeda galaxy, also known as M31, is a majestic spiral of perhaps as many as 1 trillion stars and comparable in size to our Milky Way. At a distance of 2.5 million light-years, it is so close to us that the galaxy appears as a cigar-shaped smudge of light high in the autumn sky. If its gaseous halo could be viewed with the naked eye, it would be about three times the width of the Big Dipper. This would easily be the biggest feature on the nighttime sky.

Though there is of course uncertainty here, this research is confirming earlier work, making its conclusions more robust.

A side note: Ultraviolet observations can only be done in space, as the atmosphere blocks it. Hubble I think is the only telescope in space right now with this capability. There used to be others, the most noteworthy of all being the International Ultraviolet Explorer, which functioned from 1978 to 1996 but was then decommissioned because neither NASA nor ESA were willing to fund its operation any longer.

No replacements have been launched because the budget for space astronomy has almost entirely been eaten by the overbudget and long delayed James Webb Space Telescope, with future budgets to be eaten similarly by the Roman.Space Telescope.

Canada proposes new global treaty to control mining in space

10:05 am

The globalists at the UN fight back! A Canada-led effort, endorsed by more than 140 academics, politicians, and diplomats, has proposed that the UN and international community create a new treaty to control mining in space.

Signatories to the request for the UN to intervene believe space must be regulated internationally – similarly to Antarctica or the world’s seabeds – and all countries, including non-space-faring ones, get a say in decision-making. The alternative, they warn, could be a splintered approach where companies conduct flag-of-convenience resource extraction in space under whichever country has the least onerous rules. [emphasis mine]

The Trump administration has made it clear that it wants the ability to establish U.S. law on its space operations, both in spacecraft and on its future bases on the Moon and elsewhere, an ability that the Outer Space Treaty forbids. To get around the treaty, the administration has created what it calls the Artemis Accords. The accords require that any nation that wishes to partner in the American-led Artemis program to explore and colonize the Moon must agree to support the establishment of private enterprise and ownership, with the laws of each nation applied to its own operations. To do this the Trump administration is negotiating individual bi-lateral agreements with its Artemis partners.

In essence, the U.S. is using the strategy of dividing and conquering to overcome the Outer Space Treaty’s restrictions.

Canada’s effort is designed to counter the U.S. approach, which is a strong sign that the Trump effort is working. I suspect the battle-lines are now being drawn between China and the many nations that are not operating in space (note the highlighted text), and the U.S. and those space-faring capitalistic nations that wish to partner with it, such as India and the European Space Agency. In fact, Japan and the U.S. today announced continuing negotiations leading to an agreement endorsing their partnership in Artemis, including the Artemis Accords.

Where Russia stands in this battle remains uncertain. They desperately need to partner with someone in the new effort to get to the Moon, since they no longer have the economic resources to do it themselves. The U.S. has made it clear they could join Artemis, but the Putin government opposes the Artemis Accords, preferring that the international community (meaning governments such as them) retain ownership over space resources. They have begun negotiations to partner with China, but it is unclear how much China wishes to partner with anyone.

Regardless, it would be terrible blow to freedom and private enterprise for the U.S. to agree to this Canadian-led effort. Should that approach win, it would make provide ownership and capitalism in space impossible. All power and control will devolve to the global international community, which will then dictate that nothing can happen but what it wants. For example, all the many nations incapable of doing anything in space will want a piece of the action from those nations and companies that are capable, and the result will be that no one will do anything because it simply will not be profitable. Space will simply become another failed communist state, dying before it even becomes born.

Skylab astronaut Gerry Carr passes away at 88

9:22 am

R.I.P. Gerry Carr, the commander of the last and longest Skylab mission in the 1970s, has passed away at 88.

Carr’s first and only spaceflight was as the commander of Skylab 4 (also referred to as SL-4 or “Skylab 3” as appeared on the crew’s mission patch). The third of three crewed stays of increasing duration aboard the orbital workshop, Carr and his Skylab 4 crewmates, Ed Gibson and William “Bill” Pogue, set what was then a record spending 84 days in space.

“We proved, I think, just absolutely, positively that the human being can live in weightless environment for an extended period of time,” Carr said during a NASA oral history interview in October 2000. “But medically, we gathered the data that I think gave the Russians and other people the understanding and the courage to say, ‘Okay, we can stay up for longer periods of time.'”

The obituary at the link includes Carr’s lifelong effort to explain that the crew never “mutinied,” as the press has tried to say for decades. Instead, they spent days and repeated long communications with mission control trying to get it to understand that the crew was being overworked because NASA was micro-managing their workload from the ground. They finally made mission control recognize this, after a long public conversation. Sadly, NASA had to relearn this lesson again in the 1990s during its first long missions on the Russian Mir space station (See chapters 3 and 12 in Leaving Earth).

UAE’S Hope Mars Orbiter images Mars

9:09 am

The United Arab Emirates’ (UAE) Hope Mars Orbiter has successfully imaged Mars for the first time using its star tracker camera, proving both that the spacecraft is on course and that its pointing capabilities are working as well .

“The Hope probe is officially 100 million km [60 million miles] into its journey to the Red Planet,” Mohammed bin Rashid Al Maktoum, prime minister of the UAE, wrote on Twitter on Monday (Aug. 24). “Mars, as demonstrated in the image captured by the probe’s star tracker, is ahead of us, leaving Saturn and Jupiter behind. The Hope probe is expected to arrive to Mars in February 2021.”

The star tracker is designed to keep Hope on course, telling the spacecraft precisely where it is. In addition, the probe carries a more traditional camera for use once it arrives at Mars and begins its science work.

Arrival in Mars orbit will take place in February ’21.

Astronomers discover three merging supermassive black holes

9:03 am

Using telescopes on Mauna Kea in Hawaii, astronomers have discovered three different galaxies that have pairs of supermassive black holes at their center, with all three likely to merge at some point in the future.

First the scientists used the Subaru Telescope to survey more than 34,000 known quasars, high energy supermassive black holes.

The team identified 421 promising cases. However, there was still the chance many of these were not bona-fide dual quasars but rather chance projections such as starlight from our own galaxy. Confirmation required detailed analysis of the light from the candidates to search for definitive signs of two distinct quasars.

Using Keck Observatory’s Low Resolution Imaging Spectrometer (LRIS) and Gemini Observatory’s Near-Infrared Integral Field Spectrometer, Silverman and his team identified three dual quasars, two of which were previously unknown. Each object in the pair showed the signature of gas moving at thousands of kilometers per second under the influence of a supermassive black hole.

From this survey work they now tentatively estimate that only 0.3% of all known quasars are likely made up of a binary, which in turn gives them a rough estimate of how often galaxies with such supermassive black holes collide and merge. This in turn helps them develop theories on galaxy formation.

Delta 4 Heavy launch scrubbed

11:15 pm

Tonight’s launch of ULA’s Delta 4 Heavy was scrubbed due to a variety of technical problems. They have not set a new launch time, though they say they are aiming for the early morning hours of August 28.

This was to have been the first of four American launches in the next four days. The next, a Falcon 9 launch of an Argentinian radar Earth observation satellite, was scheduled for tomorrow, August 27th, at 7:19 pm (Eastern). No word on whether it is going forward as planned, though it might be since the ULA launch has shifted after it, to August 28th.

The third, by Rocket Lab, is presently scheduled also for August 28rd at 11:05 pm (Eastern), launching out of New Zealand.

The fourth, another SpaceX launch of more Starlink satellites, had been scheduled for 10:30 am (Eastern) on August 29th. Once again, this schedule could change due to tonight’s ULA scrub.

Stay tuned. I suspect all three companies are going to aggressively work to get all four launches off as fast as possible, even if not exactly as presently scheduled.

What OSIRIS-REx will grab from the asteroid Bennu in October

6:16 pm

Closest view of Nightingale taken by OSIRIS-REx

On August 11th the spacecraft OSIRIS-REx did a sample grab-and-go rehearsal that put the spacecraft as close as 135 feet from the asteroid Bennu. During the rehearsal the spacecraft’s mapping camera (MapCam) snapped 22 images of the approach, showing the landing site, dubbed Nightingale, at the highest resolution yet.

From those images the science team created a movie. To the right is the closest image from that movie, lightened slightly and reduced to post here. It gives us the best view of the Nightingale landing site we will have prior to the October sample grab.

In essence, we are looking at the material that OSIRIS-REx will grab, though which particular rocks will be grabbed from this gravel pile are of course unknown. The spacecraft’s equipment is designed to capture pebbles smaller than 0.8 inches across. There are a good number of such rocks here, interspersed with a lot of larger rocks, including the several more than a foot across.

As I have noted previously, this landing site is about half the diameter of the landing sites the spacecraft was designed to touch down on. The rehearsal however gives us strong hope that OSIRIS-REx will be able to hit the bullseye. See this second movie, which shows the approach from two different cameras, with a wider context image provided to show how the spacecraft successfully hones in on its target.

The view from the cockpit

6:01 pm

An evening pause: This short video shows us what it is like for the pilot and co-pilot as they prepare for departure from Frankfurt, Germany, on a cargo flight to Africa and beyond. Note that even though the crew is German and the airport is German, all communications with the control tower are in English. Note also that their altitude is recorded in feet, not meters. The American big lead in the commercial airline industry in the first half of the 20th century allowed it to set the standards, including the use of feet and English in these matters.

Five charts prove the continuing COVID-19 panic unwarranted

4:08 pm

Link here. Not surprisingly, the U.S. is doing better than almost every other country in the world, and the numbers also show that the epidemic is dying off.

On confirmed cases per million, the U.S. ranks 9th, but this is in part due to the extensive testing we’ve done. In fact, despite what Biden and Co. will have you believe, we are in the top of the pack when it comes to COVID-19 tests per capita. (Note that only four of the other 36 Organization for Economic Cooperation and Development nations do better than the U.S. on tests per capita. Also, every country that does better than the U.S. has a significantly smaller population — some just tens of thousands. In fact, if you add up the populations of every country in the top 17, it equals a little more than half the U.S. population. )

When it comes to the case fatality rate – the share of confirmed cases who have died – there is no comparison. Not only does the U.S. outperform most countries – as well as the world overall – the case fatality rate in the U.S. has been steadily declining.

Finally, there’s the chart Democrats really don’t want you to see: The number of new COVID-19 cases peaked a month ago and has been trending downward ever since.

Make sure you take a look at where Sweden stands when compared to everyone else. For a country that imposed no odious lock downs, their numbers are quite good, and in fact beat nations like Italy and the United Kingdom, which imposed strict rules and house arrests.

NASA/Boeing set summer ’21 for first manned Starliner mission

4:00 pm

Capitalism in space: NASA and Boeing have tentatively scheduled the launch of the first manned Starliner mission to ISS for the summer of 2021.

Boeing Co said on Tuesday it aims to redo its unmanned Starliner crew capsule flight test to the International Space Station (ISS) in December or January, depending on when it completes software and test hardware production development.

If the test mission is successful, Boeing and NASA will fly Starliner’s first crewed mission in summer 2021, with a post-certification mission roughly scheduled for the following winter, the company added.

Everything of course depends on the success of the unmanned demo flight. If the capsule has any further problems, as it did on its first unmanned demo flight, the manned flight will likely be delayed again.

Wormlike glacier on Mars

9:30 am

Glacial flow in the mid-latitude southern cratered highlands
Click for full image.

Cool image time! The image to the right, cropped and reduced to post here, shows a very typical glacial-type feature found frequently in the mid-latitudes of Mars. Taken on May 23, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it is labeled a “Lobate Flow Feature within Channel in Nereidum Montes.” Nereidum Montes is a rough mountainous region along the northwestern margin of Argyre Basin, the second largest impact basin on Mars, after Hellas Basin.

Scientists using Europe’s Mars Express orbiter have already found a great deal of glacial evidence in these mountains. I have also posted images of other glacial features on the north edge of Argyre. This image just reinforces that data.

This particular glacier however resembles the kind of glaciers one sees on Earth more than most Martian glaciers. As it meanders down its valley, large cracks form near its edges as friction slows their passage and drags them apart. In fact, the glacier itself might have very well carved the canyon. According to Dan Berman, senior scientist at the Planetary Science Institute in Arizona, who had requested this image,

While I can’t say for sure, the canyon was likely formed by a glacier. Whether or not the ice that remains today is part of that glacier, or one that formed later, is impossible to say.

Virgin Galactic searching for profits outside of space tourism

7:52 am

Not a surprise: After almost two decades of development and no commercial suborbital tourism flights, the new management of Virgin Galactic (with Richard Branson having sold off his majority shares) is now searching for other ways to make money with its assets.

Among them, renting out the WhiteKnightTwo (WK2) launch support aircraft for government or private businesses to use for science, research, and national security applications. There’s just one problem: Legally it cannot do that.

Because WhiteKnightTwo is considered an experimental aircraft by the Federal Aviation Administration using it in this manner would be a violation of 14 CFR 91.319(a)(2), which states that “no person may operate an aircraft that has an experimental certificate – (1) For other than the purpose for which the certificate was issued; or (2) Carrying persons or property for compensation or hire.” In a filing made Tuesday The Space Company and Virgin Galactic jointly petitioned for exemption from the regulations.

It appears the new management is recognizing that the suborbital tourism market is weak (with the coming of orbital tourism), and needs to shift gears, any way it can.

The colors of Mars

1:07 pm

The different colors of Mars
Click for full image.

Actually today’s cool image tells us less about the real colors on Mars and much about the colors captured by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The photo on the right was taken on May 2, 2020, and shows a relatively featureless area to the east of 80-mile wide Byrd Crater in the high southern latitude of Mars.

The only major features seen on this photo are a series of rounded ridges that in the larger context map at the image site look almost like drainage hollows coming down from the crater’s rim about twenty miles away.

The colors, though exaggerated and not entirely as the eye would see them, still tell us something very real about the surface. As explained here [pdf]:

In spite of the variable level of color enhancement for the Extras products, we can make some generalizations to better understand what the stretched color images are showing. Dust (or indurated dust) is generally the reddest material present and looks reddish in the RGB color. … Coarser-grained materials (sand and rocks) are generally bluer … but also relatively dark, except where coated by dust. Frost and ice are also relatively blue, but bright, and often concentrated at the poles or on pole-facing slopes. Some bedrock is also relatively bright and blue, but not as much as frost or ice, and it has distinctive morphologies.

Thus, this photo is telling us that the lower areas are covered with dust (the red), while the rounded ridgelines are covered with coarser and bigger rocks. The brightest blue, which is facing towards the south pole, might also indicate frost or ice.

Report: Astronomy threatened by satellite constellations

11:31 am

A report issued today, resulting from a video conference of astronomers in July, has concluded that much of ground-based astronomy is threatened by the new large satellite constellations being launched by SpaceX, OneWeb, and others.

The astronomers’ report offers six solutions for solving the problem.

  • Launch fewer or no LEOsats. However impractical or unlikely, this is the only option identified that can achieve zero astronomical impact.
  • Deploy satellites at orbital altitudes no higher than ~600 km.
  • Darken satellites or use sunshades to shadow their reflective surfaces.
  • Control each satellite’s orientation in space to reflect less sunlight to Earth.
  • Minimize or eventually be able to eliminate the effect of satellite trails during the processing of astronomical images.
  • Make more accurate orbital information available for satellites so that observers can avoid pointing telescopes at them.

Notice what solution they don’t offer? Maybe astronomy should focus on building space-based telescopes, where the view would be clear, unimpeded by both the satellites and (much more importantly) the atmosphere.

In fact, the claim in the first solution above, that launching no satellites is “the only option identified that can achieve zero astronomical impact” is intellectually dishonest. All astronomers have to do is get their observatories into space, something that is very doable and affordable with today’s cheaper launch capabilities and technology. In space the impact of the satellites will once again be zero. And they will have the added benefit of getting outside the atmosphere, which by the way is actually a bigger limitation to observations than any satellite constellation.

It seems to me that this report was written by the faction of astronomers who make their living building big ground-based telescopes. Rather than think of solutions, they want to protect their turf by attacking the achievements of others.

A nuclear battery that never needs charging?

10:14 am

A California company, NDB (which stands for nuclear diamond battery), is developing a nuclear battery using waste products from nuclear power plants that will never need charging and will be able to replace almost any ordinary battery, from those used in computers and smart phones to AA and AAA batteries.

The heart of each cell is a small piece of recycled nuclear waste. NDB uses graphite nuclear reactor parts that have absorbed radiation from nuclear fuel rods and have themselves become radioactive. Untreated, it’s high-grade nuclear waste: dangerous, difficult and expensive to store, with a very long half-life.

This graphite is rich in the carbon-14 radioisotope, which undergoes beta decay into nitrogen, releasing an anti-neutrino and a beta decay electron in the process. NDB takes this graphite, purifies it and uses it to create tiny carbon-14 diamonds. The diamond structure acts as a semiconductor and heat sink, collecting the charge and transporting it out. Completely encasing the radioactive carbon-14 diamond is a layer of cheap, non-radioactive, lab-created carbon-12 diamond, which contains the energetic particles, prevents radiation leaks and acts as a super-hard protective and tamper-proof layer.

To create a battery cell, several layers of this nano-diamond material are stacked up and stored with a tiny integrated circuit board and a small supercapacitor to collect, store and instantly distribute the charge. NDB says it’ll conform to any shape or standard, including AA, AAA, 18650, 2170 or all manner of custom sizes.

The company says it has already built a proof-of-concept, and will begin building commercial prototypes as soon as it can reopen (they were shuttered by the Wuhan flu panic).

More at the link. Also see the video below the fold. To say this technology would be game-changing is an understatement of epic proportions. At the same time, a lot of difficult work will be required to make it practical and affordable. Don’t expect this to be available in stores for at least a few years.

Russia to spend $470 million to restore Sea Launch

9:51 am

The Russian government today revealed that it has agreed to spend $470 million to restore the Sea Launch floating launchpad.

Before Russia took possession the platform had been stripped of much of its equipment, probably as part of the final financial settlement with Boeing, which had once been a part owner (with Russia and the Ukraine). As part of the break-up of the company Russia had had to buy Boeing off (after many lawsuits) to gain full ownership.

As noted by Deputy Prime Minister Yuri Borisov, “It is a unique structure unparalleled in the world. Some have plans for building something similar. It would be very silly of us, if we decided against restoring the Sea Launch and using its services. Technically all this is possible.”

For Russia the platform gives them the potential of a launch site at the equator, something they have never had.

Four American launches in the four days

9:39 am

UPDATE: Rocket Lab’s launch has been delayed to 11:05 pm (Eastern) August 28 due of weather.

Beginning tomorrow, the next four days will be very busy for the American space rocket industry, with three companies attempting to complete four different launches.

First comes Rocket Lab, which will attempt its first launch of its Electron rocket since its first operational launch failure on July 4. Launch is scheduled for 11:05 pm (Eastern) on August 26th.

Next ULA is scheduled to use its most powerful rocket, the Delta 4 Heavy, to put a National Reconnaissance Office surveillance satellite into orbit. Launch is set for 2:12 am (Eastern) on August 27th. This very expensive rocket (which costs three to four times that of a Falcon Heavy) has only four launches left before being permanently retired.

Then SpaceX will attempt two launches in quick succession. The first will launch at 7:19 pm (Eastern) on August 27th, putting up an Argentinian Earth observation radar satellite. On this launch the first stage is a new one, and will attempt the first landing at Cape Canaveral since March 2020.

SpaceX will then follow with its third Starlink launch this month and twelfth overall, scheduled for 10:30 am (Eastern) on August 29th out of its facility at Cape Canaveral, assuming the other launches at Kennedy go as planned.

Moreover, the startup smallsat rocket company Astra is also aiming to attempt its first test launch before the end of August. The date is not yet set.

Busy times for sure, but note that this is only the beginning. I expect by the end of the 2020s the launch schedule will get increasingly packed. Soon having three three launches per week will seem routine.

Another professor arrested for lying about ties to China

9:07 pm

This is beginning to be a weekly event: Today another professor, this time from Texas A&M, was arrested for lying in grant applications by not disclosing his university affiliations in China.

Professor Zhengdong Cheng, 53, is charged with conspiracy, making false statements and wire fraud. Cheng led a team conducting research for NASA while secretly working with China, according to federal investigators.

“Dr. Cheng is accused of hiding his affiliation with the Guangdong University of Technology, along with other foreign universities, while disregarding the rules established under his NASA contract during his employment at TAMU,” said FBI Houston Special Agent in Charge Perrye K. Turner.

More and more it looks to me as if China cannot invent anything themselves, only update what they steal.
