China completes first launch of Long March 8 rocket

The new colonial movement: China today successfully launched for the first time its new Long March 8 rocket, designed at some point to mimic the Falcon 9 by vertically landing its first stage and reusing it. (Note: link fixed!)

On this launch the rocket had no such recovery capability.

The U.S. still leads China 40 to 34 in the national rankings.

Samples from space!

Scientists from both the Japanese Hayabusa-2 mission to the asteroid Ryugu and the Chinese Chang’e-5 mission to the Moon announced yesterday the total amount of material they successfully recovered.

The numbers appear to diminish the Japanese success, but that is a mistake. Getting anything back from a rubble-pile asteroid that had never been touched before and is much farther away from Earth than the Moon was a very great achievement. The 5.4 grams is also more than fifty times the minimum amount they had hoped for.

This is also not to diminish the Chinese achievement, They not only returned almost four pounds, some of that material also came from a core sample. They thus got material both from the surface and the interior of the Moon, no small feat from an unmanned robot craft.

Scientists from both nations will now begin studying their samples. Both have said that some samples will be made available to scientists from other countries, though in the case of China it will be tricky for any American scientist to partner with China in this research, since it is by federal law illegal for them to do so.

SpaceX completes 25th orbital launch in 2020

Capitalism in space: SpaceX today successfully completed its 25th orbital launch in 2020, using its Falcon 9 rocket to put an American spy satellite into orbit.

The first stage successfully landed at Cape Canaveral, completing its fifth flight.

Not only is 25 launches in a single year a new record for SpaceX, it is also four more launches than the company predicted it would achieve in 2020.

This was also the 40th successful American orbital launch in 2020, the first time since 1968 that the U.S. has had that many launches. In 1968 the launches were almost all dictated by the government, on rockets controlled by the government. Today, the rockets are all privately designed and owned, with the small number of government launches occurring with the government merely the customer buying a product.

The leaders in the 2020 launch race:

33 China

The U.S. now leads China 40 to 33 in the national rankings. The rankings also should not change significantly in the last two weeks of the year, as the U.S. has no more scheduled launches and China and Russia only one.

Subaru Telescope photographs Hayabusa-2’s next target asteroid

In order to better constrain its orbit, the Subaru Telescope in Hawaii has obtained new photographs of Hayabusa-2’s next target asteroid, 100-foot-wide 1998 KY26.

This asteroid is predicted to approach to within 0.47 AU of Earth in mid to late December 2020, giving us a rare opportunity that comes only once every three and a half years. However, the diameter of 1998 KY26 is estimated to be no more than 30 meters, and thus its brightness is so dim that ground-based observations of the asteroid are difficult without a very large telescope.

The observations with the Subaru Telescope were conducted upon the request of the Institute for Space and Astronautical Science (ISAS), JAXA. And as a result, 1998 KY26 was photographed in the direction of the constellation Gemini as a 25.4-magnitude point of light with a measurement uncertainty of 0.7 mag. The positional data collected during these observations will be used to improve the accuracy of the orbital elements of the asteroid. Similar observations were conducted with the Very Large Telescope (VLT) of the European Southern Observatory (ESO).

If all goes right Hayabusa-2 will rendezvous with 1998 KY26 in the summer of 2031.

NASA decides to fly Orion with failed power unit

Because a repair would delay the first SLS launch for months if not a year, NASA has decided to fly Orion on that November ’21 mission with failed electronics power unit.

In a Dec. 17 statement, NASA said it had decided to “use as is” one of eight power and data units (PDU) on the Orion spacecraft, which provide communications between the spacecraft’s computers and other components. One of two redundant channels in one of two communications cards in that PDU is not working.

…NASA, in its statement about deciding not to replace the PDU, did not go into details about the repair options, but said that the risks of damaging the spacecraft during the PDU repair outweighed any loss of data should the unit completely malfunction.

Engineers, the agency stated, “determined that due to the limited accessibility to this particular box, the degree of intrusiveness to the overall spacecraft systems, and other factors, the risk of collateral damage outweighed the risk associated with the loss of one leg of redundancy in a highly redundant system.”

“NASA has confidence in the health of the overall power and data system, which has been through thousands of hours of powered operations and testing,” the agency added, noting that the PDU in question was still “fully functional.”

Let’s then assess Orion. The contract was issued to Lockheed Martin in 2006. In the fourteen years since Congress has spent about $17 billion on this manned capsule. In that time it has flown once, during a test flight that was intended to test its heat shield, even though when that flight happened NASA had already decided that it was not going to use the heat shield design it was testing.

Orion’s second flight in November ’21 will be unmanned, but it will be flying with this failed unit. The next time it is supposed to fly will be in ’24, when NASA is hoping to send astronauts on a lunar landing missions. By that time NASA will have spent about $20 billion on Orion, and gotten two test capsules (both unrepresentative of the flight model) plus one manned mission.

Would you fly on this capsule under these circumstances? I wouldn’t, especially considering the non-track record of its rocket, SLS.

As the taxpayer, do you think you’ve gotten your money’s worth from this capsule? I don’t. I think it has been an ungodly waste of money, and a demonstration of the incapability of NASA and the big space contractors Boeing and Lockheed Martin of getting anything accomplished. Depend on them, and you will never go anywhere.

Terraced mesas in Martian crater

Terraced mesa in Martian crater
Click for full resolution image.

The cool image to the right, reduced and annotated to post here, was a captioned photo released by the Mars Reconnaissance Orbiter (MRO) science team earlier this week. Taken by MRO’s high resolution camera, it shows in color a beautifully stair-stepped mesa located in an unnamed 22-mile-wide equatorial crater in Arabia Terra, the large transitional zone between the lowland northern plains and the southern cratered highlands. As the caption notes,

Several craters in Arabia Terra are filled with layered rock, often exposed in rounded mounds. The bright layers are roughly the same thickness, giving a stair-step appearance. The process that formed these sedimentary rocks is not yet well understood. They could have formed from sand or volcanic ash that was blown into the crater, or in water if the crater hosted a lake.

If volcanic ash, the layers are signalling a series of equal eruptions of equal duration, which seems unlikely. Water is also puzzling because of the equatorial location. Like yesterday’s mystery cool image, water is only likely here at a time when the red planet’s rotational tilt, its obliquity, was much higher, placing this at a higher latitude than it is today.

Regardless, make sure you look at the full image here. This crater floor is chock-full of more such terraced mesas, some of which are even more striking than the sample above.

I have also posted below the MRO context camera photo of the entire crater.

Russia successfully launches another group of OneWeb satellites

Russia today successfully launched the first group of OneWeb satellites since that company entered and left bankruptcy, and it did it for the first time from its new Vostochny spaceport.

The Soyuz rocket’s flight path (see the map at the link) also took it for the first time northward over Russia, where it dropped its boosters and stages. No word on whether any villages or homes were hit.

The 36 satellites launched raises OneWeb’s constellation to 110 satellites total.

The U.S. continues to lead China 39 to 33 in the national rankings. A SpaceX launch, originally set for yesterday, has been delayed until tomorrow due to an tank pressure issue with its upper stage.

A splat on Mars

Cool image time! The photo to the right, cropped to post here, was taken on October 31, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labelled simply as a “Terrain Sample”, it was not taken as part of any specific science research but because the MRO science team need to regularly take pictures to maintain the camera’s temperature. When such engineering images are required they try to pick spots of some interest, but sometimes the resulting picture is somewhat bland.

If you look at the full image, you will see that blandness generally describes it. However, in the upper left corner was a most intriguing-looking crater, which I have focused on above. From all appearances, when this impact happened the ground was quite soft, almost like mud, and thus the ejecta splattered away not as individual rocks and debris but as a flow.

The map below gives a little context, but really doesn’t explain this crater fully.

Using origami to design spaceship fuel bladders

Capitalism in space: Engineers at Washington State University have developed a new design for a collapsible fuel bladder for spaceships using as its basis the Japanese art of origami.

Washington State University researchers have used the ancient Japanese art of paper folding to possibly solve a key challenge for outer space travel – how to store and move fuel to rocket engines. The researchers have developed an origami-inspired, folded plastic fuel bladder that doesn’t crack at super cold temperatures and could someday be used to store and pump fuel.

The advantages of a fuel tank that will shrink as it empties are numerous. It appears that nothing that has been tried so far has worked as well as this new design. If proven viable, it will change radically how interplanetary spaceships are designed. It will also make interplanetary missions more practical.

An update on the testing of SLS’s core stage

Link here. The article provides more information on the temperature issue that caused the seventh of eight fueling tests of the core stage to abort early.

The temperature issue arose when NASA transferred superchilled liquid oxygen, to fuel the rocket, from a holding facility to the core stage of the SLS. This procedure has been modeled and verified before, Julie Bassler, SLS stages manager at Marshall, told reporters during the same teleconference. But this was the first time the transfer actually took place.

“We were actually just a few degrees different than what we wanted to see coming in,” she continued, but said the temperature must be precise during the initial phases of filling the tank. The requirement is minus 290.57 degrees Fahrenheit (minus 179.21 degrees Celsius.) But the liquid oxygen was slightly cooler, at minus 296.67 degrees Fahrenheit (minus 182.59 degrees Celsius).

“We filled up [the tank] just enough to pass the phase where we knew we weren’t going to be able to get the temperature to a level that was going to be acceptable to meet the requirement, and that’s when they caught us … in the testing,” Bassler continued.

Despite this issue, NASA still hopes to do the last core stage test, dubbed the Green Run, in the last week in December. During that static fire test they will fuel the core stage entirely and then fire its engines for the full duration of an actual launch — almost ten minutes. If all goes well they will then pack up the stage and ship it to Florida for the planned November unmanned test mission sending Orion around the Moon.

They have no schedule margins, however, because all the components of this very expensive and complex rocket need a lot of time to get anything done. The two solid rocket boosters that will be attached to the sides of the core stage only have a twelve month lifespan once assembled, and they are holding off assembling them pending this test. The core stage itself needs two months to be disassembled, and then two months to be reassembled in Florida. And there remain the issue of a failed power unit in the Orion capsule that could take four to twelve months to repair.

The article however had this telling quote, based on comments from a NASA official, about future launch procedures, that sent a chill up my spine:

India successfully completes second launch in 2020

Using its PSLV rocket India today successfully placed a communications satellite into orbit.

This was only the second launch by India in 2020. At the start of the year ISRO had predicted they would complete as many as twelve launches. Instead, their panic over COVID-19 shut them down.

The leader board for the 2020 launch race presently stands unchanged, though a SpaceX rocket is on the launchpad and might lift-off in the next 90 minutes. [UPDATE: SpaceX has stood down and will try again tomorrow.]

Chang’e-5 sample return capsule successfully recovered in China

The new colonial movement: The sample return capsule for China’s Chang’e-5 mission, the first to bring lunar samples back to Earth since 1976, has been successfully recovered in the inner Mongolia region of China today.

Chinese officials confirmed the roughly 660-pound (300-kilogram) capsule landed at 12:59 p.m. EST (1759 GMT) Wednesday, or 1:59 a.m. Thursday in Beijing.

Recovery crews dispatched to the remote landing zone converged on the capsule in helicopters and off-road vehicles, traveling across the snow-covered plains of Inner Mongolia in the middle of the night. Ground teams reached the Chang’e 5 return module within minutes to begin operations to secure the capsule, and planted a Chinese flag in the frozen soil next the spacecraft.

Crews plan to transport the module to Beijing, where scientists will open the sample carrier and begin analyzing the moon rocks.

For China this success is a major milestone for its government-run space program. They have demonstrated superb technical capabilities that will serve them on many more future missions. They have also signaled to the world and the U.S. that they mean business in space, and that their published plans to build colonies on the Moon are serious. They have also made it clear that they will enforce control over any territory they occupy, notwithstanding the rules of the Outer Space Treaty. Any American government that makes light of these facts and refuses to aggressively compete with China is going to quickly discover it shut out of the most valuable locations on the Moon.

InSight: Mars’ crust is thin, and its interior is many layered with a molten core

Scientists yesterday released results from the seismometer on the Mars InSight lander that suggest that the crust of the red planet is thin and that its interior is many layered with a molten core.

[T]wo moderate quakes, at magnitude 3.7 and 3.3, have been treasure troves for the mission. Traced to Cerberus Fossae, deep fissures in the crust 1600 kilometers east of the landing site that were suspected of being seismically active, the quakes sent a one-two punch of compressive pressure (P) waves, followed by sidewinding shear (S) waves, barreling toward the lander. Some of the waves were confined to the crust; others reflected off the top of the mantle. Offsets in the travel times of the P and S waves hint at the thickness of the crust and suggest distinct layers within it, Brigitte Knapmeyer-Endrun, a seismologist at the University of Cologne, said in an AGU presentation. The top layer may reflect material ground up in the planet’s first billion years, a period of intense asteroid bombardment, says Steven Hauck, a planetary scientist at Case Western Reserve University.

At 20 or 37 kilometers thick, depending on whether the reflections accurately trace the top of the mantle, the martian crust appears to be thinner than Earth’s continental crust—a surprise. Researchers had thought that Mars, a smaller planet with less internal heat, would have built up a thicker crust, with heat escaping through limited conduction and bouts of volcanism. (Though Mars is volcanically dead today, giant volcanoes dot its surface.) A thin crust, however, might mean Mars was losing heat efficiently, recycling its early crust, rather than just building it up, perhaps through a rudimentary form of plate tectonics, Mojzsis says.

The thin crust provides a solid basis for explaining the large volcanoes and vast lava plains on the planet. Combined with the light gravity, magma would have found an easier path to the surface. Handed this knowledge, planetary geologists can now make a first stab at outlining more precisely the planet’s early volcanic history.

SpinLaunch expands operations at Spaceport America in NM

Capitalism in space: SpinLaunch, the private launch startup that proposes to fling payloads into orbit rather than launch them in a rocket, has announced that it will be expanding its operations at Spaceport America in New Mexico.

The company already built a $7 million, 10,000-square-foot facility at the Spaceport after announcing plans last year to conduct all testing there on its new technology. Now, the company is doubling down, with plans to hire an additional 59 people and invest another $46 million over 10 years. The state Economic Development Department will support the expansion with $4 million in Local Economic Development Act funding, said EDD Secretary Alicia J. Keyes.

…Under its expansion, the company plans to actually build the centrifuge launch system at the spaceport, with test launches to start next year. “We expect by next summer to begin flight test operations at the spaceport, and we expect to continue to test new flight designs there for the foreseeable future,” Yaney told the Journal. “We see it as a permanent facility for us.”

The idea is fascinating, but I have some doubts. First, the accelerations will be so high that it might limit the company’s customer base, since many satellites will likely not be able to withstand those forces.

If it works, however, the company will have found a truly clever way to eliminate entirely the need for a first stage, and maybe even the second stage.

ESA funds ArianeGroup prototype vertical landing hopper

The European Space Agency (ESA) has now committed 33 million euros for ArianeGroup to develop a prototype vertical landing hopper dubbed Themis that would begin testing first stage landings by ’23.

ArianeGroup and its collaborators in Belgium, Switzerland, France and Sweden offer critical technical knowhow gained through the development of Europe’s next-generation engine – Prometheus – which will power Themis.

ESA’s Prometheus is a highly versatile engine capable of providing 1000 kN of variable thrust and is reignitable which makes it suitable for core, booster and upper stage application. An onboard computer handles engine management and monitoring in real time – a crucial feature for reusability.

ArianeGroup is the private consortium led by Airbus and Safran that is building Ariane 6. This deal suggests that ESA amd ArianeGroup has finally recognized that Ariane 6, built without reusability, is a lemon and is not attracting customers. This new contract starts the process of developing a reusable first stage.

They still might be too late. They will only begin testing the Themis prototype in ’23, with no clarity on when a full scale version will follow. Meanwhile, it is very likely that SpaceX’s fully reusable Starship/Super Heavy will be flying orbital missions by then, and likely charging far less than they presently do for their Falcon 9.

Cones on Mars!

Today’s cool image is actually a bunch, all found recently in the monthly image download from the high resolution camera on Mars Reconnaissance Orbiter (MRO).

All the photos I post below show pimple-like cones, all of which appear to be a type of small volcano. The cones are found in a wide range of locations, from the northern lowland plains to the cratered highlands to the mid-latitude transition zone between the two. They are also found at the bottom of deep canyons, in the floors of craters, and amidst mountains.

Let us begin.

Astra test launch almost reaches orbit

The view from space on Astra's Rocket

UPDATE: The rocket came up slightly short of orbit. From Eric Berger:

Rocket was 0.5 km/s short of orbit. With a better fuel mixture in the upper stage it would have orbited. Apogee of 390km. Rocket 3.3 will carry a payload, and there will be no hardware or software changes.

Original post:
——————————
Capitalism in space: According to the company’s Twitter feed, the second launch attempt today by Astra of its rocket appears to have reached orbit.

The images to the right were taken by their rocket, which is unimaginatively dubbed Rocket 3.2. I hope they now give this vehicle a more striking name.

If they have succeeded, they will have joined Rocket Lab as one of only two private commercial smallsat startups to launch a rocket to orbit. Two Chinese pseudo-private companies, Galactic Energy and ExSpace, have accomplished this, but I do not count them as real private companies. They might have worked independent of the government and raised investment capital, but nothing they do happens without close government supervision.

We will have to wait for full flight data from the company, but assuming they reached orbit that will be 40th American launch in 2020, the first time the U.S. has topped 40 launches in a single year since 1969, when the country achieved 46 successful orbital launches.

Ancient and recent volcanoes on Mars

Volcanic vent on eastern flank of Olympus Mons
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on October 25, 2020. It shows what it calls a “possible volcanic vent east of Olympus Mons”.

Is this active? If not, how old is it. Also, the elongated shape of the vent suggests the possibility of a lava tube, or at least some underground complexity to the release of its magma.

In order to get some clarity, I emailed Sarah Sutton of the Lunar and Planetary Laboratory of the University of Arizona, who requested this photograph. Her response:

The image is of a small shield volcano with an elongated vent at the summit. We don’t have complete stereo here yet, so we can’t tell exactly what the height is. This vent might have sourced tube-fed flows, but in this case, we can’t resolve such features in the image data. This and other small shield volcanoes in the vicinity are partially buried by plains-forming lava flows. The lava flows around the base overlap the flows that emanate radially from the summit vent. Therefore we infer that the shield is older than the surrounding lava flows.

The vent, which runs from the southwest to the northeast, sits on top of a sloping wide hill, which is that small shield volcano described by Sutton. The flat plains surrounding this hill are from later eruptions from other and possibly larger volcanoes. The wider overview map below might give us a clue as to the source.

This was the company’s sixth successful launch in 2020, matching the count it had predicted at the start of the year it would reach. And this despite one launch failure. The rocket also sported a new and larger faring, giving Rocket Lab the ability to launch larger payloards or more satellites with each launch.

Confirmed: Martian glacial features are ice

Lobate glacial flows on Mars
Click for full image.

Scientists using the radar instrument on Mars Reconnaissance Orbiter (MRO) have now confirmed that the Martian glacial features that most resemble the glaciers seen on Earth are made of substantial amounts of ice, and were possibly active and growing only a few million years ago.

“Our radar analysis shows that at least one of these features is about 500 meters thick and nearly 100 percent ice, with a debris covering at most ten meters thick,” said Berman, lead author of “Ice-rich landforms of the southern mid-latitudes of Mars: A case study in Nereidum Montes” published online in Icarus at https://doi.org/10.1016/j.icarus.2020.114170. PSI scientists Frank C. Chuang, Isaac B. Smith and David A. Crown are co-authors on the paper.

Global mapping of Viscous Flow Features (VFFs), a general grouping of ice-rich flow features in the southern hemisphere of Mars shows a dense concentration in Nereidum Montes, along the northern rim of Argyre basin. Located within a northwestern subregion of Nereidum Montes is a large number of well-preserved VFFs and ice-rich mantling deposits, the paper says, potentially the largest concentrations of any non-polar region in the southern hemisphere.

…Processed data from the Shallow Radar (SHARAD) instrument aboard NASA’s Mars Reconnaissance Orbiter spacecraft were used to search for basal reflections across VFFs within the region. For one in particular, these observations and analysis indicate that it is composed of nearly pure water ice. Model ages obtained from crater counts and their associated size-frequency distributions (SFDs) on both ice-rich mantling deposits and small lobate VFFs suggest that the deposits stabilized several to tens of millions of years ago in the Late Amazonian Epoch, and that small lobate VFFs likely formed due to the mobilization of mantling deposits.

This data here reinforces the impressions from many other places within the 30-60 degree latitude bands on Mars where many such features are found.

Mars might be a desert, but it is a desert like Antarctica, not the Sahara. Any settlement there must use the Earth’s south pole as its guide for construction and design.

Russia successfully completes second Angara rocket launch

SpaceX successfully launches commercial radio satellite

Capitalism in space: SpaceX today successfully launched a new commercial radio satellite for Siruis.

The first stage was making its seventh flight, the fifth in 2020. It successfully landed on the drone ship. The fairings were also both previously flown.

The leaders in the 2020 launch race:

33 China
24 SpaceX
13 Russia

5 Rocket Lab
5 Europe (Arianespace)

The U.S. now leads China 38 to 33 in the national rankings. The U.S. has also completed the most launches in a single year since 1968. Unlike 1968, all the launches this year were flown by private companies, either for commercial customers or for the government, with rockets owned by the companies. In 1968 almost all the launches were for the government, and the rockets were controlled by the government, even if built by private companies.

Note that this very successful year occurred during a year when many businesses were forced to shutdown due to the Wuhan panic. It appears many rocket companies decided this was not a reason to cease operations.

Virgin Galactic’s first Unity launch from New Mexico fizzles

Capitalism in space: Virgin Galactic’s first attempt to launch its SpaceShipTwo Unity suborbital spacecraft from its New Mexico spaceport ended almost immediately after the ship was released from WhiteKnightTwo when its engines did not ignite.

All appeared normal during the flight’s early phases. VSS Unity was carried into the air by its twin-fuselage mothership, known as WhiteKnightTwo VMS Eve, and was released to fly free at an altitude of more than 40,000 feet.

A webcast provided via NASASpaceflight.com showed the flash of the plane’s hybrid rocket motor lighting up, but only for a second. After the flame-out, Test pilots Dave Mackay and C.J. Sturckow brought Unity back down to the spaceport for a gliding landing.

I wish Virgin Galactic well, but at this point consider the company a backwater in the drive to develop a commercial space tourism industry. It took them too long to get to this point. Even if they should start flying tourists next year, they will be competing with orbital tourist flights by SpaceX, and the contrast is stark. I simply no longer see a viable customer base for Virgin Galactic, unless they get a lot of government subsidies.

Indonesia & SpaceX considering launchsite there

Capitalism in space: Indonesia has been in discussions with SpaceX and Elon Musk about establishing a SpaceX launch site in that country.

President Joko Widodo discussed the idea with SpaceX founder Elon Musk during a phone call on Friday, the Coordinating Ministry for Maritime and Investment Affairs said in the statement. Musk intends to send a team to Indonesia in January to study partnership opportunities, it said.

Makes sense for Musk to consider such a move, especially if the U.S. and Texas governments start to turn the screws on his Boca Chica launch site. Furthermore, it is his intention to eventually launch Starship/Super Heavy from a floating launch platform. Establishing arrangements with other foreign nations for putting it in their waters gives the company more flexibility.

People always migrate toward freedom. For two hundred and fifty years, that meant they moved to the United States. This now is changing, as the U.S. culture is signaling its increased hostility to this most important founding principle. Expect more stories like this in the coming decades.

New data confirms and localizes uplifted lunar dust as seen by Apollo astronauts

The uncertainty of science: In a paper released today, scientists reveal the detection of electrostatic dust events on the Moon similar to those observed by Apollo astronauts, and find that these events might not be global but instead confined to craters during twilight. From the abstract:

Lunar horizon glows observed by the Apollo missions suggested a dense dust exosphere near the lunar terminator. But later missions failed to see such a high‐density dust exosphere. Why the Apollo missions could observe so large number of dust grains remains a mystery. For the first time, we report five dust enhancement events observed by the Lunar Dust Experiment on board Lunar Atmosphere and Dust Environment Explorer [LADEE] mission, which happen near a twilight crater with dust densities comparable to the Apollo measurements. Moreover, the dust densities are larger on the downstream side of the crater and favor a higher solar wind temperature, consistent with an electrostatic dust lofting from the negatively charged crater floor. We also check the Apollo observations and find similar twilight craters, suggesting that the so‐called dust exosphere is not a global phenomenon but just a local electrified dust fountain near twilight craters.

The dust clouds the astronauts thought they saw near the horizon have been theorized to be dust uplifted by static electricity. However, all later missions had so far failed to detect this phenomenon, until now. That the result also pinpoints the location and ties it to twilight is important for future missions to the Moon. Astronauts can thus minimize any damage by this dust by shutting down operations during lunar twilight periods.

Breaking: Starship prototype #9 tips over inside assembly building

It appears from the 24-hour live stream provided by LabPadre that the ninth Starship prototype tipped over inside the assembly building to rest against one wall. You can see it happen at about 8 seconds into the video below:

No word on whether anyone was hurt, nor any information about the cause. My guess is that it occurred during the operations to move this prototype to the launchpad.

UPDATE: It appears no one was hurt, but there is damage to the fins, which might also mean damage to the hull. This in turn might make it unsafe to fly this prototype, as the hull forms the walls of the methane/oxygen tanks.

The day has not been good for SpaceX. Earlier they had to scrub the launch of a commercial communications satellite at T-30 seconds for reasons that they did not provide. High altitude winds had delayed the launch an hour or so, but it appears this was not the reason. According to SpaceX’s website, “SpaceX is standing down from Friday’s launch attempt of the SXM-7 mission to perform additional ground system checkouts.” They are targeting Sunday for the next launch attempt.

Strange crater in the basement of Mars

Strange crater in Hellas Basin
Click for full image.

Today’s cool image to the right, cropped and reduced to post here, is intriguing for a number of reasons. Taken on September 11, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows a partially buried crater found in the middle of Hellas Basin, the lowest point on Mars and what I like to call the red planet’s basement.

What makes this crater intriguing is the layered pile of material filling its interior. If I didn’t know any better, I would think some construction crew has used a bulldozer to push debris from the crater’s right half in order to smooth the ground in preparation for building a strip mall, office building, or housing development.

This of course is not what happened. Then what did create those layered piles in the crater’s left half?

Watch ULA try again to launch its Delta-4 Heavy

Capitalism in space: ULA will today try once again, after numerous scrubbed and aborted attempts in August and September, to launch its Delta-4 Heavy rocket carrying a National Reconnaissance Office spy satellite.

The mission is set to take off at 6:15 p.m. EST (2315 GMT) Thursday from pad 37B at the newly-renamed Cape Canaveral Space Force Station in Florida. Forecasters predict near-ideal weather with a 90% chance of favorable conditions during the launch window Thursday evening.

Many of the launch problems earlier this year were due to issues in the launch pad. The article at the link describes the major refurbishing that ULA has done since then to fix them.

I have embedded their live stream of the launch, below the fold. It is set to go live at 5:55 pm (Eastern).

Note also that the next few days will be very busy for the American rocket industry. Tomorrow (Friday) both SpaceX and Astra have launches scheduled, with the latter making its second attempt to complete its first orbital launch. Then Rocket Lab has another Electron launch from New Zealand scheduled for the next day (Saturday).

That’s four launches in three days. If just two succeed, it will raise the total U.S. launches in 2020 to 38, which would be the most American launches in a single year since 1969, the year the country put men on the Moon.

Smallsat rocket startup Obex raises $24 million

Capitalism in space: The smallsat rocket startup Obex of the United Kingdom today announced that it has raised $24 million in private investment capital to support the development of its Prime rocket.

Conceived and developed as an environmentally sustainable launch system, the Orbex Prime rocket uniquely uses bio-propane, a renewable biofuel that cuts CO2 emissions by 90% compared to traditional kerosene-based rocket fuels. Designed to be recoverable and re-usable, Orbex Prime is intended to leave no debris in the ocean or in orbit around the Earth. The company is constructing the rocket vehicle at factories in Forres, near Inverness in Scotland, and Copenhagen in Denmark.

…Orbex has already confirmed six commercial satellite launch contracts, with the first launches expected in 2022. The company’s preferred launch site will be the Sutherland spaceport on the northernmost coast of Scotland, which was granted planning permission in mid-August 2020.

Whether the Sutherland spaceport happens however remains uncertain. Though it still appears to be moving forward, there is a lot of local opposition to it, some with clout. It appears however that Orbex is aware of this reality, and is developing Prime to allow it to launch from other sites.

That the company is trying to build this rocket as reusable right from the beginning is encouraging. It shows that the rocket industry is finally accepting the new paradigm established by SpaceX. For them to achieve this by ’22 however will be quite challenging.
