Rocket Lab becomes third rocket company to go public

9:46 am

Capitalism in space: On August 25, 2021 Rocket Lab became the third rocket company to go public, following Virgin Galactic and Astra to sign a merger deal with a special-purpose acquisition company (SPAC).

Nasdaq celebrated the milestone, inviting Rocket Lab founder and CEO Peter Beck to ring the market’s opening bell Wednesday morning.

The SPAC merger, with a San Francisco-based company called Vector Acquisition Corporation, provides Rocket Lab with about $777 million. The funds will aid the development of multiple projects, including Rocket Lab’s big, next-generation Neutron rocket, company representatives said.

Nor is this all. Virgin Orbit has also signed a similar deal this wee, and will begin trading stock soon.

All these deals indicate that the investment community is very confident in making big profits in space, and is now willing to commit a lot of cash to that prospect.

ULA to no longer sell Atlas-5 launches

9:36 am

Capitalism in space: In an interview ULA’s CEO Tory Bruno has announced that they have contracts on all of the company’s remaining Atlas-5 rockets, and will no longer be offering that rocket for new sales.

“We’re done. They’re all sold,” CEO Tory Bruno said of ULA’s Atlas V rockets in an interview. ULA, a joint venture between Boeing and Lockheed Martin, has 29 Atlas V missions left before it retires sometime in the mid-2020s and transitions to its upcoming Vulcan rocket, Bruno said. The remaining Atlas V missions include a mix of undisclosed commercial customers and some for the Space Force, NASA, and Amazon’s budding broadband satellite constellation, Project Kuiper.

This means that the company is now firmly committed to its Vulcan rocket, which also means it is entirely committed to the repeatedly delayed BE-4 engine that Blue Origin is building for that rocket. This announcement suggests that Bruno is confident that the BE-4’s problems have been overcome, and that Blue Origin is about to begin regular assembly of the many flightworthy engines ULA will need.

If so, this is really good news. It not only means that Vulcan launches will finally begin, but that Blue Origin might also begin flying its New Glenn rocket. Both will give the U.S. some competitive options for getting big payloads into space. Right now the only real choice at a reasonable price is SpaceX, and having one choice is never a good thing.

Amazon protests SpaceX’s Starlink plan to FCC

9:23 am

Amazon on August 25, 2021 filed a protest with the FCC against SpaceX’s proposed expansion of its Starlink constellation that would allow almost 30,000 satellites to be launched.

“Should the Commission depart from its rules and precedent and endorse the approach of applying for multiple, mutually exclusive configurations, the consequences will extend far beyond the SpaceX Amendment,” wrote Mariah Shuman, corporate counsel for Amazon’s broadband megaconstellation venture Project Kuiper, in an Aug. 25 letter to the FCC. “However inefficient this strategy might be for the Commission and parties responding to applications, other prospective licensees will surely see the benefit in maximizing their optionality by describing multiple configurations in their license applications.”

Shuman asked the FCC to “dismiss SpaceX’s Amendment, and invite SpaceX to resubmit its amendment after settling on a single configuration for its Gen2 System.”

It appears Amazon does not want the FCC to approve multiple proposed satellite configurations put forth by SpaceX in a single application. Instead, it wants the FCC to force SpaceX to pick one, and submit that alone. It also appears that doing what Amazon requests would be more in line with past FCC policy.

While Amazon might have a point, the optics once again make another Jeff Bezos’ company look ugly, more interested in using the courts to stymie its competitors than actually launching anything. Amazon’s Kuiper internet constellation was first proposed in early 2019. More than two years have passed and none of its more than 3200 satellites have launched — not even one test satellite — with no clear indication yet on when launches will finally begin.

SpaceX began testing its Starlink system in 2018, and already has about 1,700 operational satellites in orbit. The comparison between the two companies is stark, and not favorable to Amazon.

In fact, Elon Musk was not shy in taking advantage of these optics to note them quite sharply in a tweet yesterday, saying, “Turns out Besos [sic] retired in order to pursue a full-time job filing lawsuits against SpaceX.”

Amazon is not Blue Origin, but both companies were founded by Bezos, and it appears right now that both prefer court battles to rocket engineering.

Webb telescope finally completed, ready for shipment to launchpad

2:15 pm

After more than two decades of construction (ten years behind schedule) and more than $10 billion (20 times the original cost), the infrared James Webb Space Telescope has finally completed its testing and is ready for shipment to its launch site in French Guiana to be mounted on an Ariane 5 rocket.

Now that observatory testing has concluded, shipment operations have begun. This includes all the necessary steps to prepare Webb for a safe journey through the Panama Canal to its launch location in Kourou, French Guiana, on the northeastern coast of South America. Since no more large-scale testing is required, Webb’s clean room technicians have shifted their focus from demonstrating it can survive the harsh conditions of launch and work in orbit, to making sure it will safely arrive at the launch pad. Webb’s contamination control technicians, transport engineers, and logistics task forces are all expertly prepared to handle the unique task of getting Webb to the launch site. Shipping preparations will be completed in September.

If all goes well, NASA and ESA hope to launch the telescope in late October. It will then take about six months for the telescope to unfold and reach its operating position a million miles from Earth in the Earth’s shadow.

Let us all pray that everything works. If it does not, there will be nothing that can be done to fix it for probably at least five years, if then, as it will be out of reach of any maintenance mission, manned or unmanned.

Today’s blacklisted American: World’s top vaccine expert censored by Twitter & LinkedIn and punished by the CDC

12:14 pm

No real scientists allowed!
The opinions of real scientists banned!

They’re coming for you next: Even as Martin Kulldorff, a Harvard medical professor and one of the world’s foremost experts on vaccines, has been repeatedly censored by Twitter and LinkedIn, he has been banned and punished by the CDC for daring to publicly dissent from its government lockdown and mask and vaccine mandate policies.

First, I think it important to know who Martin Kulldorff is. This article provides a succinct resume of his qualifications:

Dr. Martin Kulldorff is a professor of medicine at Harvard Medical School and a biostatistician and epidemiologist at the Brigham and Women’s Hospital. He helped develop the CDC’s current system for monitoring potential vaccine risks.

Then there is this opinion by one of his collegues:

Kulldorff is a “world-class” vaccine safety “superstar,” said Jeffrey Brown, a Harvard Medical School colleague specializing in drug and vaccine safety research. “His qualifications are spectacular,” Brown said of Kulldorff. “He’s an international expert in vaccine safety. No one on earth would question whether he’s qualified. … He’s a pioneer.”

And yet, he has now become a pariah on social media as well as at the CDC, all of whom are apparently no longer interested in a robust and honest discussion about COVID.

ULA rolls Vulcan core first stage to launchpad for tank tests

9:26 am

Capitalism in space: ULA yesterday rolled out a test Vulcan core first stage to its launchpad for a variety of tests in preparation for its first launch, now delayed until next year.

The rocket’s core stage will undergo Pathfinder Tanking Tests (PTT) at Space Launch Complex-41 at Cape Canaveral Space Force Station. It is outfitted with two development BE-4 engines that will be replaced by flight engines before launch. The tanking, or fueling, tests will validate launch pad infrastructure, evaluate countdown procedures, and train the launch team.

That these launchpad tests were delayed until now suggests that ULA had hoped to do them with the flightworthy engines, and then follow-up quickly with Vulcan’s first orbital launch in the fall. With the admission this week by both Blue Origin and ULA that the flightworthy BE-4 engines would not be delivered this summer as promised, ULA probably decided it was better to get this testing done now with the development engines, in order to save prep time for when the flightworthy engines finally arrive.

Thus, the delays at Blue Origin are costing ULA money. Once the flightworthy engines are installed, ULA will still need to do static fire launchpad tests, which means they will have to do much of this test program all over again. The extra countdown rehearsals are of course beneficial, but they are an extra expense, and also require extra time.

ULA’s CEO, Tory Bruno, has tried very hard to streamline ULA’s operations so they are more efficient and thus more competitive. Blue Origin’s failure to deliver on time is making Bruno’s effort very difficult.

It also shows that SpaceX’s policy of building as many of its components in-house, instead of depending on outside contractors, makes sense. And that all of the new rocket companies are doing the same proves that others agree. ULA’s dependence on others for its rocket engines will thus in the long run put it at big competitive disadvantage.

Spanish judge invalids agreement to build TMT in Canary Islands

9:05 am

The consortium attempting to build the Thirty Meter Telescope (TMT), blocked by protesters in Hawaii, has now had its back-up location in the Canary Islands blocked by a Spanish judge, who last month invalidated the agreement between the consortium and local authorities.

[A]n administrative court in Santa Cruz de Tenerife, the capital of the Spanish archipelago, ruled last month that the 2017 concession by local authorities of public land for the tentative project was invalid. The ruling was dated on July 29, but only became public this week after local media reported about the decision.

In the ruling obtained by The Associated Press, Judge Roi López Encinas wrote that the telescope land allocation was subject to an agreement between the Canary Astrophysics Institute, or IAC, and the telescope’s promoter, the TMT International Observatory (TIO) consortium. But the judge ruled that the agreement was not valid because TIO had not expressed an intention to build on the La Palma site instead of at the Hawaii site.

In other words, it appears the agreement was ruled invalid because the TMT builders had not made a firm commitment about building at the Canary Islands.

At this moment it truly looks like TMT is dead. It has no alternative site, and its political support in Hawaii is nil. While the Democratic Party politicians that rule that state have mouthed support for it, almost all their actions since the protests began has been to help the protesters and stymie construction.

What I think will soon begin happening is that the partners in TMT will begin to back out, switching their support to the other large ground-based telescopes being planned, the Giant Magellan Telescope and the European-Extremely Large Telescope. Since these are both being built in Chile, the loss of TMT means that there will be no large ground-based telescope coverage of the northern sky.

The real solution? Stop building ground-based telescopes. Put them in space, where such political issues won’t exist, and the view will be unimpeded by either the atmosphere or the tens of thousands of new satellites expected to launch in the coming years.

Blue Origin successfully completes another unmanned suborbital flight with New Shepard

8:47 am

Capitalism in space: Only one month after its first passenger flight, Blue Origin today successfully completed another suborbital flight with its New Shepard booster/capsule, this time flying 18 commercial payloads for NASA and others.

These details about the spacecraft itself I think are significant:

The New Shepard booster, Tail 3, and its associated capsule, RSS H.G. Wells, flew the mission. Tail 3 is dedicated to uncrewed science missions like NS-17, and this was Tail 3’s 8th flight.

…Blue Origin expects to fly one more New Shepard mission this year with sister ship Tail 4 and the crew-capable capsule RSS First Step

In other words, Blue Origin now has two working New Shepard spacecraft. This will allow them to eventually up their launch pace.

Today’s blacklisted American gets an apology from Illinois regulators for threatening his medical license for opinions they didn’t like

2:39 pm

Today’s blacklist story is actually an update from my blacklist story two days ago about Dr. Jeremy Heinrichs, who because he had publicly expressed strong skepticism about the mask mandates being imposed by his state government in Illinois, had been threatened with the loss of his medical license by state regulators.

It appears those regulators have now quickly apologized for getting caught acting like jack-booted thugs.

“The initial response to your inquiry requested information that the Department does not need,” Dina Martin, an attorney with the Illinois Department of Professional and Financial Regulation, said in a letter to Henrichs’ legal counsel. The department had originally asked for “a detailed statement on your opinion about masks, and whether you support and will enforce a mask mandate based on your elected position as a school board member.”

“I sincerely apologize for the tone and content of those communications,” Martin said in her August 19 letter, obtained by Just the News.

It also appears that the regulators plan to drop their complaint investigation.

This is how you treat bullies. You don’t back down. You don’t apologize. And you certainly don’t hide in shame out of fear their unjustified attacks will hurt you. No, you fight back hard, and brightly expose them for all to see. Like all bullies they will immediately back off themselves, especially if their attack has no merit (which is almost always the case).

There is no indication however that the regulators who sent those improper initial communications have been punished in any way. I expect not. The Illinois government got caught this time, but has no intention of preventing this from happening in the future. If anything I expect the government has simply asked these employees to lay low for awhile and try the same thing again later, in the hope that others will be more easily intimidated.

To really fix this the voters need to fire everyone in these governments, from the Democratic Party elected officials who control Illinois to the lowest bureaucrat who thinks such behavior can sometimes be justified.

Perseverance’s upcoming targets: sand ripples, rocks, and a lot of dust

2:17 pm

Ingenuity's view during 12th flight

Cool image time! The photo to the right was one of ten color images taken by Ingenuity on its twelfth flight on August 15, 2021. This photo is one of two images looking the same area from slightly different positions in order to create a stereoscopic view, with the other image found here.

The ground the helicopter was scouting, dubbed South Seitah, is an area that the Perseverance team hopes to send the rover. Ingenuity’s images from this flight will not only tell them whether the terrain is safe to traverse, it will allow them to map out a route that will avoid problems while effectively targeting the most interesting rocks.

The photo shows a lot of Martian dust, with a good portion forming small sand dune ripples. The rocks appear to be bedrock pavement stones, which because these are on the floor of the crater and the lowest elevation, likely hold the oldest geology that Perseverance will see on its journey in Jezero Crater. For this reason the science team is spending a lot of time studying that floor, and will make probably several drilling attempts to obtain samples.

The terrain in general looks entirely safe for the rover to travel. I expect the science team will thus continue north, crossing to North Seitah, rather than backtrack and travel over already traversed ground. Initially they had decided to avoid this ground because they feared it might be too rough for the rover. I suspect they were just being overly cautious at the start of the mission, and will now work past that fear.

Musk’s Boring Co offers to dig tunnel for resident transportation during launch closures

1:49 pm

Capitalism in space: Elon Musk’s Boring Company has proposed digging a tunnel so that people can still access Boca Chica’s beaches even during periods when SpaceX is doing launch operations and needs to close the surface roads.

The Boring Company (TBC) met with Cameron County officials to discuss the possibility of a tunnel project running from South Padre Island (SPI) to Boca Chica Beach.

The Boring Company pitched the idea of an SPI-Boca Chica tunnel to Cameron County administrator Pete Sepulveda Jr. and county engineer Benjamin Worsham early this summer. Cameron County officials have been thinking of giving people access to part of Boca Chica Beach even during closures.

The county has said it likely cannot afford to pay for such a thing, but Musk’s company is still proposing to do an in-depth study to find out what will be necessary to make it happen.

It could very well be that Musk might find some cash to help pay for this himself. The public relations would be excellent, and it would I think be the right thing to do. It is also possible that the local communities will have more cash themselves because of the booming economy SpaceX is bringing them.

Blue Origin BE-4 engine delayed again

10:14 am

In an interview ULA’s CEO Tory Bruno revealed that Blue Origin is not going to deliver the first two flightworthy BE-4 engines this summer, as promised, with delivery now probably not until the end of the year.

“I will not get them before the end of the year,” said Tory Bruno, CEO of ULA, in an exclusive Denver Business Journal interview ahead of this week’s Space Symposium industry gathering in Colorado Springs. “It will be shortly into the beginning of the 2022 calendar year, and anywhere in there will support me being able to build up a rocket and have that Vulcan waiting on my customer, Astrobotic.”

…“We’ve actually be been able to accommodate this, but I’ll be straight with you, the dates we’ve set up for them now— we really don’t have the ability to make any big moves after this,” Bruno said. “I need them to diligently work through the plans we have and get done on time.”

ULA needs to launch its new Vulcan rocket twice in order to get approved for its first military launch, now expected in less than 12 months. They thus no longer have any schedule margin.

China completes two launches

2:23 pm

China today successfully completed two launches, using from different spaceports its Long March 2C and Long March 3B rockets.

The 2C launched a two demo internet communications satellites designed to eventually be used in a large constellation similar to the constellations of SpaceX and OneWeb. The launch also included a third unidentified communications satellite.

The 3B placed in orbit what is believed to be a military reconnaissance satellite.

Both rockets dumped their first stages somewhere in the interior of China. No word on whether those stages carried parachutes or grid fins to better control their landing, or crashed near habitable regions.

The leaders in the 2021 launch race:

29 China
20 SpaceX
13 Russia
4 Northrop Grumman

The U.S. still leads China 31 to 29 in the national rankings.

Today’s blacklisted American: A man’s life destroyed because he visited the Capitol on January 6th

Show trials: The Biden administration’s goal for pro-Trump protesters

Genocide is coming: Because the Biden Justice Department is determined to throw the book at him, the life of truck driver Robert Reeder has been thoroughly shattered, losing his job and friends and even alienating his family, simply because he decided to participate in the protests at the Capitol on January 6th and got caught up in the chaos that ensued.

All the evidence suggests that Reeder, along with almost all the protesters on January 6th, did nothing particularly violent. Their actions were spontaneous (as an FBI investigation has reluctantly admitted), and mostly peaceful. Moreover, Reeder’s behavior, along with his fellow pro-Trump protesters, pales in comparison to the violence and rioting committed routinely by leftist protests from Antifa and BLM, for which they are never charged or punished.

Wind-blown dark material on Mars

Dark wind-blown material on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a cluster of small depressions from which has blown dark material across the ground to the south. The full image also shows two craters north and south of this cluster that have similar dark material blown from their interiors.

When I first looked at this image, I wondered if the dark material and these depressions signaled a recently active volcanic vent where magma had spewed upward to stain the nearby ground. See for example this recent post about what some scientists believe might the most recent volcanic event so far found on Mars. I emailed several scientists for their thoughts, all of whom said this appears to not be active volcanism but merely windblown dark material.

Kim Seelos, science operations lead for MRO’s visible-near infrared spectrometer, put it simply. “My own reading of this image is that the dark areas here are likely akin to wind streaks.” Instead of the dark material being thrown from the depressions by a volcanic event, it was swept to the south by the prevailing winds.

How that dark material got into the depressions, and why it was so comparably darker than the surrounding terrain, remains unclear. David Horvath of the Planetary Science Institute in Arizona speculated that the low hills just north of the dark patch might be a factor.

First hi-res radio wavelength images of metal asteroid Psyche

9:46 am

Psyche in thermal

Using the ALMA telescope in Chile astronomers have obtained the highest resolution radio images of the surface of the metal-rich asteroid Psyche yet obtained. The image to the right is from their just published paper. From the article:

These new images reveal that some regions of the asteroid have surface temperatures different from the average, indicating that Psyche’s composition is not uniform. The researchers also found that Psyche has a relatively high thermal inertia compared to other asteroids, yet it radiates approximately 60% less heat than would be expected for an object with such a high inertia. The researchers hypothesize that this is because the asteroid’s surface is at least 30% metal. However, the light reflecting off Psyche’s surface is unpolarized, which would not be the case for an object with a smooth or solid metallic surface. They therefore hypothesize that metallic grains are spread throughout its surface material, causing the light to scatter.

Though Psyche is large, 178 by 144 by 101 miles, it is not spherical like Ceres, the largest asteroid in the asteroid belt at 580 miles diameter. Thus, somewhere from the size of Psyche to the size of Ceres we move from an irregular asteroid body to a spherical planetary body, as it appears most planetary scientists define planets.

The probe Psyche is scheduled to launch in August ’22 to arrive at Psyche in ’26.

ISS spacewalk postponed due to “minor medical issue”

9:16 am

NASA announced yesterday that a spacewalk planned for today on ISS has been postponed because of ” a minor medical issue” involving American astronaut Mark Vande Hei.

This issue is not a medical emergency. The spacewalk is not time-sensitive and crew members are continuing to move forward with other station work and activities. Teams are assessing the next available opportunity to conduct the spacewalk following the SpaceX CRS-23 cargo resupply launch planned for Aug. 28 and upcoming Russian spacewalks.

The NASA announcement provided no other information, which is unfortunate. While Vande Hei’s medical privacy must be respected, his decision to not disclose the issue will only fuel some foolish speculation that is likely false. It is always better to be transparent.

Update: It appears the medical issue was a pinched nerve, which will likely cause the spacewalk to be delayed into September at the soonest.

Ispace’s 3rd lunar lander to be larger, built entirely in U.S.

9:06 am

Capitalism in space: The private Japanese company Ispace announced yesterday that its third lunar lander will be larger (to provide more payload space for customers) and built entirely in U.S. (to better garner NASA contracts).

The lander, being developed by the company’s U.S. office in Denver, will fly as soon as 2024 on the company’s third mission to the moon.

A major difference in the new design, company officials said in interviews, is the payload capacity. While the lander ispace is building for its first two missions in 2022 and 2023 can carry 30 kilograms of payload to the lunar surface, the new lander will have a payload capacity of 500 kilograms to the surface. It will also be able to deploy an additional 2,000 kilograms of payloads to lunar orbit.

The company is also hardening the lander to survive the two week long lunar night.

The decision to shift operations to the U.S., and partner with U.S. companies General Atomics and Draper, makes Ispace a viable competitor for later NASA contracts, which in turn can encourage other privately funded payloads to sign on.

Today’s blacklisted American: Illinois threatens to cancel doctor’s license because it doesn’t like his opinions

3:46 pm

The Bill of Rights cancelled in Illinois
No first amendment in Illinois

They’re coming for you next: State regulators in Illinois are threatening to take away a medical license of a doctor, Jeremy Heinrichs, because he has publicly challenged the mask mandate being imposed by his state government.

In a provided statement, Henrichs said: “I have considered authoritative medical evidence that questions the necessity of mandatory masking in our schools. As a result, the [Illinois Department of Financial and Professional Regulation] has threatened my medical licensure unless I expressly support and enforce a mask mandate for all students.

“The [IDFPR] has commanded me to ‘toe the line’ or suffer personal and professional consequences,” he added.

…In a separate email, a state medical investigator, whose name was redacted from the email, said a complaint filed against Henrichs “appears to be a parent or concerned citizen who did not agree with the doctor’s opinion on the masking motion for schools. That would fall under the unprofessional conduct part of the medical practice act,” the email said. “What the medical disciplinary board wants to know is if the doctor will support and enforce the mask mandate by the Governor.”

Boeing to buy part of Virgin Orbit for $3.2 billion

3:18 pm

Capitalism in space: In a stock market merger/investment deal, Boeing is going to buy a part ownership in Virgin Orbit for $3.2 billion, with the deal to close by the end of the year.

After the deal completes, Branson’s Virgin group will hold about 68 per cent of Virgin Orbit. Abu Dhabi’s sovereign wealth fund, Mubadala Investment Company, is an existing investor in Virgin Orbit and will have about 17 per cent, while the Pipe and other private investors will hold about 15 per cent of the group. Boeing’s share was not disclosed.

My first thought was that Boeing wanted to get into a space company that was doing things better than anything Boeing was trying. And considering that Virgin Orbit a Richard Branson space company, albeit one with some real success, that indicates how badly everything else is at Boeing

My second thought was: Where is Boeing getting the cash? My impression is that because of its various problems with the 737-Max, it has sold almost no planes in the past two years, and has even had to refund money from many purchasers. Its cash flow with Starliner is nil until they fly it. SLS has brought them money as the contract is cost-plus, but hardly enough to pay for this deal.

My third thought was that this deal indicates the continuing cash problems at Branson’s Virgin Group. The Wuhan panic cut airline traffic significantly. It appears Branson is still digging for cash to bail out these operations.

Why only NOW is there mounting concern over President Biden’s mental health?

12:36 pm


Biden as he forgets what truths we hold as self-evident in March 2020.

A Daily Mail story from last week reported on the growing concern of doctors and other health experts about the mental state of Joe Biden, the oldest American president ever.

Questions have been raised about US President Joe Biden’s cognitive wellbeing after a car crash interview over his handling of the unfolding Afghanistan crisis. America’s oldest president provided jumbled responses to questions and mixed up details about his son in an interview with ABC. The stumbles did not make the broadcasted version but were revealed when a full transcript of the interview was published overnight.

It revealed the President incorrectly stated his late son Beau Biden worked for the Navy in Afghanistan, before correcting himself that he served for the Army in Iraq. It follows a spate of gaffes and slips of the tongue since the 78-year-old ran his successful presidential campaign in 2019.

This story only highlights a growing slew of news stories and op-eds that have appeared recently during the ongoing debacle in Afghanistan, in both the right and leftwing press, that have noticed how President Biden appears repeatedly confused in interviews while showing signs that he does not quite understand what is going on around him.

Of course, for the press and the political class to recognize these facts now, after Biden has become president, is equivalent to closing the barn door after the animals have escaped. As I noted in October 2020, before the election, these cognitive issues have been obvious for the last two years, and had been getting steadily worse throughout 2020 during the election campaign. As I wrote then,

Two smallsat orbiters to launch in ’24 to study Martian upper atmosphere

11:53 am

NASA has picked a twin orbiter mission being built by a partnership of the University of California-Berkeley and the private rocket company Rocket Lab to place two smallsats in orbit around Mars to study how the harsh environment of space might be causing the red planet to lose its atmosphere.

The entire project is dubbed ESCAPADE (an insanely contrived acronym) but the two smallsats have been dubbed “Blue” and “Gold.”

The mission builds on decades of experience at SSL in building satellite instruments and fleets of spacecraft to explore regions around Earth, the moon and Mars, specializing in magnetic field interactions with the wind of particles from the sun. Each of the two satellites, named after UC Berkeley’s school colors, will carry instruments built at SSL to measure the flow of high energy electrons and ionized oxygen and carbon dioxide molecules escaping from Mars, magnetic field detectors built at UCLA and a probe to measure slower or thermal ions built at Embry-Riddle Aeronautical University in Daytona Beach, Florida.

With twin satellites, it is possible to measure conditions simultaneously at two places around the planet, Lillis said, allowing scientists to connect plasma conditions at one site to the escaping ion flux at another. Over the course of the mission, the two satellites will change positions to map the upper atmosphere and magnetosphere of nearly the entire planet from an altitude of between 150 and 10,000 kilometers.

Maybe the most important aspect of this mission however is not what it will learn at Mars, but how it is being financed and built. NASA is only paying about $80 million, a tiny amount compared to most past unmanned planetary probes. The university in turn is buying Rocket Lab’s Photon satellite structure rather than building the satellites from scratch. It will configure the instruments to fit into that ready made satellite body, thus saving time and money.

By doing it this way NASA and the planetary science community is increasingly relying on private companies to provide them their planetary probes, rather than building such things by hand themselves, at much greater cost. The result is a growing and thriving private commercial sector that owns and builds its own planetary probes, for profit.

Cool image time! The photo above, taken on August 22, 2021 by Curiosity’s left navigation camera and reduced to post here, looks ahead at the rover’s upcoming mountainous goals. The overview map to the right shows the area covered by this image by the yellow lines. The dotted red line indicates the rover’s original planned route, with the white dotted line its actual path of travel.

The cliff ahead is about 400-500 feet away. The top of this cliff is the Greenheugh Pediment, its blocky top geological layer visible as the dark cap at the top of the cliff face. Back in March 2020 Curiosity had climbed up to view across this pediment, from a point to the northwest and off the overview map to the left. (Go to this link to see what the view was like from there.) Since then the science team has had the rover travel quite a distance, to circle around to now approach the pediment from the east.

The white box marks the area covered by a close-up high resolution mast camera image, shown below.

Update on Starship/Superheavy preparations for orbital test flight

9:15 am

Starship prototype #20 being prepped
Screen capture from Labpadre live stream, available here.

Link here. In sum it appears that SpaceX is getting very close to launch, with the permit approval of the FAA increasingly becoming the biggest obstacle to progress.

Although the completion of all of this testing could take a long time, in Elon Musk’s mind, the path to returning B4 and S20 to being an integrated stack could be during this month.

A week ago, Musk tweeted that the “first orbital stack of Starship should be ready for flight in a few weeks, pending only regulatory approval.” Ultimately, once the vehicle is in its launch configuration, there will be a lengthy process of passing the aforementioned regulatory approval, with an environmental public comment period triggered ahead of launch. This has to be completed before the launch license can be granted by the Federal Aviation Administration (FAA).

The screen capture above shows Starship prototype #20 sitting on the suborbital flight test pad, as workers on cherry-pickers work on its exterior. The orange, green, and white tiles are likely tile locations still needing some level of installation work.

Based on SpaceX’s normal pace of operations, the engine testing for both Starship and Superheavy will take several weeks, once both are ready for such testing. While Starship appears just about ready, Superheavy apparently needs more work. When SpaceX stacked both together on the orbital launchpad several weeks ago, it suggested both were closer to launch than they were. Their present status suggests engine testing will likely begin in September, with Starship at the beginning of the month and Superheavy at the end of the month. That would make a launch possible sometime in late October, assuming the federal government doesn’t decide to shut this entire operation down by refusing to issue a permit.

Astronomers have discovered an asteroid that circles the Sun with the shortest orbit yet found, flying mostly inside the orbit of Mercury.

The illustration to the right shows the asteroids orbit, which is also tilted 32 degrees from the plane of the solar system.

The orbit of the approximately 1-kilometer-diameter asteroid takes it as close as 20 million kilometers (12 million miles or 0.13 au), from the Sun every 113 days. Asteroid 2021 PH27, revealed in images acquired during twilight, also has the smallest mean distance (semi-major axis) of any known asteroid in our Solar System — only Mercury has a shorter period and smaller semi-major axis. The asteroid is so close to the Sun’s massive gravitational field, it experiences the largest general relativistic effects of any known Solar System object.

Relatively few asteroids have been found with orbits shorter than Earth’s, because to find them astronomers have to turn their telescopes sunward, where viewing is limited to the early evening or early morning. Few space-based telescopes in all wavelengths also don’t look this way much, because of the risk of damage from the intense sunlight.

It is thus unknown exactly how many asteroids exist with similar orbits. There may be many, with many having short eccentric orbits, similar to comets, that extend out to Earth’s orbit and thus pose a risk. Or there may be few, since such orbits so close to the Sun are likely to cause the asteroid’s break-up and destruction over time.

Knowing how many of course is important, in order to obtain a full census of those asteroids in the solar system that might hit the Earth. To get it will likely require placing a probe designed to look for them.
