New cracks discovered on a different Russian ISS module

12:38 am

Russian officials revealed today that their astronauts have discovered new cracks on a different Russian ISS module, dubbed Zarya.

“Superficial fissures have been found in some places on the Zarya module,” Vladimir Solovyov, chief engineer of rocket and space corporation Energia, told RIA news agency, according to Reuters. “This is bad and suggests that the fissures will begin to spread over time.” The Zarya module, also called the Functional Cargo Block, was the first component of the ISS ever launched, having blasted into orbit on Nov. 20, 1998, according to NASA.

Russians have now found what appear to be age stress fractures on both Zarya and Zvezda, the two oldest modules of ISS. More important, the Russians are finally admitting that the cracks are stress fractures, something they had earlier denied.

The need to launch new commercial American modules to ISS as quickly as possible has now become even more urgent. Axiom plans to do so, but its first module is not scheduled to arrive before ’24. It now looks increasingly that the Russian modules might not make it till then.

German rocket company successfully tests first stage to failure

9:55 pm

Capitalism in space: The German startup rocket company Rocket Factory Augsburg has successfully completed a tank pressure test of its rocket’s core first stage, testing that stage to failure.

The German startup Rocket Factory Augsburg, or RFA, has concluded another test of their RFA One rocket. In the test, the company performed a destructive cryogenic pressure test of their first stage prototype. The company has shown a video in which the prototype stage broke apart after it was fueled with cryogenic nitrogen to test the quality of the welds and determine the pressure at which the structure fails.

The milestone is the latest for the company which is aiming to develop a reusable launch vehicle for small payloads. The first flight of RFA One is currently slated for late 2022, following more testing and development.

The video of the test, with a dramatic soundtrack (as has sadly become the practice today since all life always has its own soundtrack) can be seen at the link.

This company is one of three German private rocket startups vying to enter the smallsat launch market — Isar, RFA, and HyImpulse — with two hoping to make their first launch next year.

Context image of curving channels
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken by the wide angle context camera on Mars Reconnaissance Orbiter (MRO) in April 2019. It shows an area on Mars where a number of meandering curving channels flow downhill from the west to the east.

Earlier MRO images had already spotted these channels, so when this context image was taken the scientists also took a high resolution image of the same channels, with the white box indicating the area covered by the rotated, cropped, and reduced image below.

Both images are today’s MRO image of the day, where the MRO team notes that “The objective of this observation is to examine a complex network of channels. Some parts of the channels are quite curved.”

Astra launch failure caused by one of five 1st stage engines shutting down at liftoff

8:57 am

Capitalism in space: According to an Astra press release, its launch failure on August 28th was caused when one of the rocket’s five 1st stage engines shut down one second after liftoff.

One of the five main engines shut down less than one second after liftoff, causing the vehicle to slowly lift off the pad before resuming its trajectory. After approximately two minutes and thirty seconds of flight, the range issued an all engine-shutdown command, ending the flight.

The lack of one engine explains the rocket’s strange take-off, where it initially tilted slightly, shifted sideways, and then straightened up and began rising upward. From that point onward the ground controllers knew the mission would not reach orbit, and were only waiting until it reached a safe altitude to cut off the engines and have the rocket fall into the ocean safely.

While the launch failed, Astra’s engineers should be very satisfied by how the software on the rocket functioned. Rather than shut everything down and crashing into the launchpad fully fueled where it could do a lot of damage, the rocket immediately compensated for the loss of one engine and resumed a stable flight, allowing it to get clear.

This success does not negate the failure however. Astra needs to find out why one engine shut down.

SpaceX successfully launches cargo Dragon to ISS

12:35 am

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch cargo Dragon to ISS.

The first stage completed its fourth flight, landing successfully on the drone ship in the Atlantic. The cargo Dragon is making its second cargo mission for NASA. It will dock tomorrow.

This was SpaceX’s first launch since June 30th, a gap of almost two months as they initiated operations of a new drone ship in the Atlantic and shifted an older drone ship to the Pacific. In the next few weeks expect their fast launch pace for ’21 to resume, with at least one Starlink launch and the September 15th Inspiration4 commercial manned orbital flight.

The leaders in the 2021 launch race:

29 China
21 SpaceX
13 Russia
4 Northrop Grumman

The U.S. now leads China 32 to 29 in the national rankings.

Astra third launch attempt fails just before 1st stage engine cutoff

3:57 pm

Astra launch, August 28, 2021

Capitalism in space: The third orbital launch attempt of the smallsat rocket company Astra failed about two and a half minutes into flight, just about twenty seconds before the the first stage engine cutoff and stage separation.

It appeared that the first stage engines shut down about twenty seconds early, and then the rocket began tumbling.

I have embedded the live stream below the fold, cued to just before launch. The image to the right is a screen capture about seven seconds after liftoff. Astra’s rocket did a maneuver at launch I’ve never seen before, where it immediately tilted slightly to transition to the side, and then righted itself to begin gaining altitude. In this image the top of the strongback can be seen on the left, with the now upright rocket beginning its flight.

Whether Astra can figure out what went wrong and attempt another flight before the end of this year remains unclear. This was the third launch in their announced three launch test program, with the goal of reaching orbit on the third launch (today’s). They did not meet that goal, though their second test launch in December came extremely close to orbit with no major technical failures.

Successful orbital engineering test of magnetic space junk removal technology

10:34 am

Capitalism in space: The Japanese-based company Astroscale has successful completed its first test in orbit of a magnetic capture device designed to someday remove for space junk.

Launched on March 22, ELSA-d (short for “End-of-Life Services by Astroscale demonstration”) brought with it to orbit a 37-pound (17 kilograms) cubesat fitted with a magnetic docking plate. During the experiment on Wednesday (Aug. 25), ground controllers first remotely released a mechanical locking mechanism attaching the cubesat to the main 386-pound (175 kg) removal craft, Astroscale said in a statement. The two satellites were still held together by the magnetic system, which is responsible for capturing the debris.

The cubesat was then released completely and recaptured before floating too far away from the main spacecraft. Astroscale said on Twitter that this maneuver was repeated several times. This short demonstration enabled Astroscale to test and calibrate rendezvous sensors, which enable safe approach and capture of floating objects.

Engineers in the coming weeks plan to do even more challenging tests of ELSA, including a capture attempt where the target is made to tumble like an out-of-control satellite.

Eventually the company hopes to sell its target technology to satellite makers so that its satellites will be able to capture them. It already has a deal with OneWeb to develop this technology for its satellites, whereby one of its clean-up satellites could capture a bunch of defunct OneWeb satellites on one flight and deorbit them safely.

Whether this magnetic capture technique could be used on satellites with metal but no specifically designed target is unclear. If so it would place Astroscale a strong position to gain a large portion of the space junk removal business.

Another mountain view from Curiosity

12:33 pm

Low resolution panorama
Click for full resolution panorama. The original images can be found here, here, here, here, here, and here.

I hope my readers won’t get tired of seeing these mountain views from Curiosity, but I can’t get enough of them.

The image above is a panorama I’ve created from six photos taken by Curiosity’s right navigation camera yesterday. The box marks the location of that spectacular outcrop I highlighted in the previous mountain view five days ago. The red dotted line shows the rover’s upcoming planned route. The white cross indicates the pavement bedrock where the science team hopes to next drill.

For scale, Navarro Mountain is rises about 400 feet from where the rover presently sits. The peak of Mount Sharp is actually not visible, blocked by its near white flank on the panorama’s left edge. That peak is still 13,000 feet higher up from where the rover presently sits.

The rise of rocks next to the words “entering Gediz Vallis” is actually only probably five to ten feet high, as it is very close to the rover.

Curiosity’s travels continue to get more and more exciting to follow.

China studying the construction of large-scale structures in space

9:57 am

The new colonial movement: China has now indicated that it has established a project to study methods for building very large structures in orbit, with uses ranging from generating beamed solar power to providing mega-sized manned spaceships and space stations.

Though vague, the project would have practical applications for potential megaprojects including colossal space-based solar power stations. Such facilities would be based in geostationary orbit and span kilometers. These stations would collect solar energy and transmitting power to Earth through microwaves.

Kilometer-scale, ultra-large spacecraft are described as “major strategic aerospace equipment for the future use of space resources, exploration of the mysteries of the universe, and long-term habitation in orbit,” according to the project outline within the mathematical and physical sciences attachment to the released document.

The project would focus on minimizing the weight of the spacecraft to reduce the number of launches and construction, according to an initial report by the South China Morning Post.

It appears that this project is only in its preliminary design phase, with a budget of $3.2 million. Its existence however reinforces the overall rational and long term approach China’s government is taking to space exploration. At this moment they mean business, and are focused on getting the cutting edge technology designed and built rather then maintaining a bureaucratic infrastructure and the jobs that go with it — as NASA and Russia have been doing for the past forty-plus years.

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.

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.

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.

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.

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.

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.

Click for interactive map.

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.

Russia launches another 34 OneWeb satellites

Russia today put another 34 OneWeb satellites into orbit, using its Soyuz-2 rocket.

OneWeb now has 288 satellites in orbit, out of the planned 648. At present the constellation is able to provide service to customers in latitudes north of 50 degrees. Though SpaceX’s Starlink constellation is also offering service to customers in the same northern latitudes, the two companies service different customer bases, with OneWeb aimed at big business and government operations and Starlink aimed at individual residential customers.

The leaders in the 2021 launch race:

27 China
20 SpaceX
13 Russia
4 Northrop Grumman.

The U.S. still leads China 31 to 27 in the national rankings.

Russia delays launch of next unmanned lunar probe

9:04 am

According to a story in Russia’s state-run press, Roscosmos has decided to delay the launch of its Luna-25 lander from October 2021 to May 2022.

The story gave no reason for the delay.

Luna-25 would be the first Russian lunar probe since the 1970s, and is supposed to be that country’s first probe in a partnership with China to establish a manned lunar base by the 2030s.

Want to bet the Russian contribute to this project will be repeatedly delayed, and will also likely be disappointing? That has been the track record of Roscosmos for the past two decades (like all 21st century government projects). This first delay signals many more to come.

I am not saying Russia will fail to launch anything. What I am saying is that everyone should reserve a large store of skepticism about any promises Russia’s makes.

Top engineers and managers fleeing Blue Origin

3:58 pm

According to this story today, Blue Origin this summer lost at least sixteen top management and engineering employees, all leaving in a very short time.

At least 16 key leaders and senior engineers have left Blue Origin this summer, CNBC has learned, with many moving on in the weeks after Bezos’ spaceflight.

…Others quietly updated their LinkedIn pages over the past few weeks. Each unannounced departure was confirmed to CNBC by people familiar with the matter. Those departures include: New Shepard senior vice president Steve Bennett, chief of mission assurance Jeff Ashby (who retired), national security sales director Scott Jacobs, New Glenn senior director Bob Ess, New Glenn senior finance manager Bill Scammell, senior manager of production testing Christopher Payne, New Shepard technical project manager Nate Chapman, senior propulsion design engineer Dave Sanderson, senior HLS human factors engineer Rachel Forman, BE-4 controller lead integration and testing engineer Jack Nelson, New Shepard lead avionics software engineer Huong Vo, BE-7 avionics hardware engineer Aaron Wang, propulsion engineer Rex Gu, and rocket engine development engineer Gerry Hudak.

Those who announced they were leaving Blue Origin did not specify why, but frustration with executive management and a slow, bureaucratic structure is often cited in employee reviews on job site Glassdoor.

There is another possibility that would be more hopeful. It could be that Jeff Bezos is shaking up the company because of its poor accomplishments during the past four years, since CEO Bob Smith was hired.

That Smith however is still there makes this guess unlikely. The article also notes that Smith’s approval among Blue Origin employees is abysmal, with only 15% approving his management, when compared to high numbers given to the management leaders at SpaceX and ULA.

Thus, this exodus is more likely a sign that that the rats are fleeing what they see as a sinking ship.

It would be a mistake to dismiss Blue Origin however. The company is swimming in dough because of Bezos’ deep pockets, and he is free to do what he thinks must be done to fix things. Under such conditions it is very unlikely Blue Origin will disappear. More likely Bezos will straighten things out, though the company now has to play big catch up, not only against SpaceX but also against the fleet of new orbital rocket companies about to come on line — all doing so ahead of Blue Origin.

There is also the possibility that this story has got its facts wrong. It makes a very big error near the beginning, claiming that former SpaceX engineer Lauren Lyons had left Blue Origin to join SpaceX, when she had actually left SpaceX to take a big promotion at Firefly. My mistake. Lyons had moved from SpaceX to Blue Origin. This job change was leaving Blue Origin to go to Firefly.
