Prep of first SLS rocket continues to suggest no launch in ’21

9:28 pm

Though NASA and Boeing crews and management have been striving very hard to get the SLS rocket on the launchpad for a liftoff before the end of this year, the schedule has as expected continued to slip, with the chances of a launch by December now increasingly unlikely.

NASA engineers have not discovered any major problems during the SLS testing, but key milestones leading up to the Artemis 1 launch have been steadily sliding to the right in NASA’s processing schedule.

Before NASA raised the Boeing-made SLS core stage onto its mobile launch platform inside High Bay 3 of the VAB in June, managers hoped to connect he Orion spacecraft for the Artemis 1 mission on top of the rocket in August. That’s now expected this fall.

The first rollout of the 322-foot-tall (98-meter) rocket from the VAB to launch pad 39B was scheduled no earlier than September. That’s now expected in late November, at the soonest, according to [Cliff Lanham, senior vehicle operations manager for NASA’s exploration ground systems program].

The schedule slips, while not significant amid the history of SLS program delays, have put a major crunch on NASA’s ambition to launch the Artemis 1 mission this year. The agency is evaluating Artemis 1 launch opportunities in the second half of December, multiple sources said, but that would require NASA to cut in half the time it originally allotted between the SLS fueling test and the actual launch date.

None of this is really a surprise. NASA had always said it would take about six to ten months to get the rocket ready for launch once it arrived in Florida, and it only got there in May. That meant a late November launch could only occur if everything went perfectly. As this is the first time this rocket has ever been assembled, it is not reasonable to expect such perfection.

Based on all factors, the launch will likely occur no earlier than January, but more likely in February, at the earliest. On that schedule it is very likely SpaceX’s Starship will reach orbit first.

Stucco on Mars!

12:33 pm

Stucco on Mars
Click for full image.

Cool image time! The picture to the right, cropped to post here, was taken on June 8, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a strangely flat plain with a complex stucco-type surface of ridges and depressions. The sunlight is coming from the west, which makes the smoother flat areas depressions.

What are we looking at? What causes this strange surface? Make sure you look at the full image, because the section I cropped out doesn’t give a true sense of the terrain’s vastness.

The MRO science team labeled the photo “volcanic terrain,” but that tells only part of the story, since this volcanic terrain is actually part of Mars’ most interesting lava plains, as the overview map below shows.

South Korea to launch its own rocket in October

9:47 am

The new colonial movement: South Korea is now targeting October 21, 2021 for the first test launch of its home-built Nuri rocket.

The October flight will be South Korea’s first domestic orbital launch attempt in more than eight years. On Jan. 30, 2013, a Naro-1 rocket placed the STSAT-2C technology demonstration satellite into low Earth orbit.

It was the final of three launches for now retired Naro-1, which consisted of a Russian Angara first stage with a downgraded engine and a South Korean developed solid-fuel upper stage. Two previous Naro-1 launches failed in 2009 and 2010.

They have also scheduled a follow-up test launch in May ’22, assuming all goes well on this first test launch.

Zhurong completes 100 days on Mars

9:39 am

Zhurong's loaction, August 31, 2021

The new colonial movement: In announcing today that its Mars rover Zhurong has completed 100 days on the Martian surface, the state-run Chinese press released one very low-resolution panorama taken at the rover’s new position, and a map showing its full route since landing.

The map to the right, created by placing that route on a high resolution Mars Reconnaissance Orbiter image, shows us where Zhurong presently sits as well as where it might travel next. It still appears that they are attempting to reach the heat shield used during landing, which also suggests that they are giving high priority to the engineering aspects of this mission, possibly ranking that component higher than any science they get.

If high resolution versions of that panorama are available, they are probably only available on the Chinese language sites, which makes it very difficult for a non-Chinese-speaker to find.

According to the release, the rover has now traveled just under 3,500 feet, which means it is maintaining a pace greater than 1,000 feet per month. The release also noted this fact about the rover’s upcoming travels, as well as the Tianwen-1 orbiter being used as a communications relay satellite:

The probes will experience a sun outage in mid-to-late September when the Sun is aligned with Earth and Mars, with the solar radiation interfering with the communication between the probes and ground stations. The orbiter and rover will stop working until the sun outage comes to an end.

This conjunction occurs every two years. It means there will also be a pause in data from the American rovers and orbiters. When the last conjunction occurred in September 2019, the communications shutdown lasted about two weeks.

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.

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.

FAA’s space bureaucracy chief touts desire to limit his agency’s regulatory fist

10:18 am

Wayne Monteith, the man in charge of the FAA’s office of commercial space — which is tasked with regulating commercial space — revealed in a speech on August 25, 2021 that his goal is to speed that industry’s growth, not hinder it with odious regulations.

Wayne R. Monteith, a retired Air Force general who served for years in space billets in Colorado Springs is now the FAA’s associate administrator for commercial space transportation. He told a Space Symposium crowd at The Broadmoor Wednesday that to a large extent, he’s trying to keep his agency out of the way of the rush to space. “A regulatory agency can either be an accelerator or an inhibitor of industry,” he said. “We choose to be an accelerator.”

Sounds good, doesn’t it? Don’t be so sure. While right now Monteith noted that the agency is taking a laissez-faire approach to anyone who wants to fly in space, acting only to make sure space accidents will not harm “the uninvolved public,” he also said this in his speech:

Monteith warned, though, that mishaps for manned space flight that escalate to what he called “catastrophe,” have consequences. “The worst case is a catastrophic failure,” he said. “Then, we will regulate.”

In other words, he recognizes that if he tried now to impose his bureaucratic will on commercial space, it would not fly politically. What he really needs to expand his power is some space accident, a crisis you might say, that he can then use to convince others that he should be controlling things more.

Based on the response of the press, public, and American culture in the past half century, his thinking is quite sound. Routinely since World War II, as soon as something goes wrong in any field of endeavor the American public and political class has repeatedly wanted the government to move in and take greater control, under the false premise that somehow the government can prevent further failures.

Instead, we have accomplished less, and fueled the rise of an all-powerful bureaucracy capable and quite willing to squelch achievement. This is the pattern that Monteith is relying on, and based on recent history, he is entirely justified in believing so.

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.

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.
