Ingenuity gearing up for 30th flight

10:33 am

The engineering team for the Ingenuity helicopter on Mars announced yesterday that they have successfully completed two some spin-up tests and are preparing for the first short hop following the pause in flights during the height of the Martian winter dust season.

To confirm that she is still flightworthy, we performed a 50-rpm spin on Aug. 6, and on Aug. 15 we performed a high-speed spin, which spun up the rotor system to flight-like speeds of 2,573 rpm for several seconds. Telemetry downlinked after both tests indicates Ingenuity is a go for flight.

Our 30th flight will be similar to our second flight. On April 22, 2021, Flight 2 was the first to include sideways movement: We “translated” 13 feet (4 meters) and then returned before landing. Flight 30 will be shorter, translating sideways only 7 feet (2 meters) and then landing, but with the specific goal of providing a data point on Ingenuity’s ability to accurately approach a landing target. Our navigation system’s performance will be of value to the Sample Recovery Helicopter team (part of the Mars Sample Return Program) in their early design work for a next-generation Mars Helicopter navigation system.

The last sentence references the recent decision to use a helicopter on the future sample return mission to land near the cached Perseverance samples and grab them.

The 30th flight is supposed to occur sometime in the next few days.

SpaceX and China complete launches

12:51 pm

Two launches have just occurred in the 2022 launch race. First, SpaceX today successfully launched another 53 Starlink satellites, using its Falcon 9 rocket.

The first stage successfully landed on its drone ship in the Atlantic, completing its ninth flight.

China in turn used its Long March 2D rocket to launch three military reconnaissance satellites, at what was the early morning hours of August 20, 2022, China time. The launch path took the rocket over China’s interior as well as Taiwan, with the first stage crashing somewhere in China.

The leaders in the 2022 launch race:

37 SpaceX
31 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 52 to 31 in the national rankings, and the entire world 52 to 49. The 52 launches so far this year is now the fifth best total for the U.S. since the launch of Sputnik in 1957.

Strings in Perseverance’s drill?

12:01 pm

String in Perseverance's drill
Click for full image.

Since August 5th, the Perseverance science team has been trying to figure out the origin as well as the consequences of “two string-like pieces” of foreign object debris (FOD as used by today’s acronym-happy scientists) that they have spotted next to one of the rover’s coring drill bits.

The photo to the right, cropped and reduced to post here, looks directly down at that core drill bit and shows one of those strings both to the side of the bit as well in full resolution in the inset. From today’s update:

Since first identified Aug. 5 in imagery of the rover’s sample collection system after a 12th rock core sample was taken, the FOD has been the focus of several methodical diagnostic activities in an attempt to better understand the nature of the debris.

We’ve commanded the rover to move, rotate, or vibrate components we think could harbor FOD. And we’ve obtained multiple sets of images of the components from different angles and in different lighting conditions from rover cameras: Mastcam-Z, Navcam, Hazcam, Supercam, and even the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera located on the rover’s turret. Finally, a thorough review of recent coring and bit-exchange activities confirm that they all executed nominally with no indication of interference from the FOD.

Analysis of the latest round of imaging, downlinked earlier today, indicates that while the two small pieces remain visible in the upper part of the drill chuck, no new FOD has been observed. In addition, imagery taken of the ground beneath the robotic arm and turret, as well as the rover deck, also showed no new FOD.

Because these strings do not appear to interfere in any way with the drill’s operation, the science team has decided neither is a cause for concern, and will therefore command the rover to leave this just-completed drill site and move on to the southwest to a location at the base of the delta the rover visited about three months ago.

The strings themselves are likely pieces from the equipment released during the rover’s landing, and might even have come from the tangled string the rover imaged on the nearby ground in July, and that was gone just four days later. The wind had blown it away, and may have even at that time blown pieces into the drill.

Indian company delivers Gaganyaan fairing and high altitude launch abort motor to ISRO

10:28 am

Capitalism in space: The Indian private company, Hindustan Aeronautics Limited, yesterday delivered to India’s space agency ISRO the fairing and high altitude launch abort motor that will be used in Gaganyaan, that nation’s first manned spaceflight.

Though the article at the link does not say so, the fairings and abort motor will likely be used in one of two unmanned launch abort test flights ISRO intends to do before the actual manned mission, now set for sometime in ’24.

Hindustan Aeronautics is also a space company in India that will require watching. It not only built these major components for Gaganyaan, it also has built major components for India’s PSLV and GSLV rockets. It would not surprise me if the company eventually decides to build its own rocket, assuming the India government loosens the stranglehold it presently has over space and lets private companies compete against its government space operations. It was a similar stranglehold by NASA from the 1970s to the 2000s that squelched competition and innovation from the American private aerospace industry. When that ended, the renaissance in commercial space finally could begin.

UPDATE: It appears I was in error assuming Hindustan Aeronauts was a private company, as it is owned by the Indian government. I have edited the post above to reflect this. It appears the stranglehold the government has over India’s aerospace industry is no closer to loosening.

Firefly completes a dress rehearsal countdown of Alpha rocket; schedules launch

10:14 am

Capitalism in space: Having successfully completed both a full dress rehearsal countdown and static fire test of its fully stacked Alpha rocket, Firefly Aerospace has now scheduled the rocket’s launch for September 11, 2022.

These details come from a tweet by the company, so details are very limited. Nonetheless, this will be the company’s second attempt to complete an orbital launch. The first attempt, in September 2021, failed when one of its first stage engines shut down prematurely.

The company had hoped to attempt this second launch ten months ago, but was forced to delay it when the federal government demanded its chief investor, Ukrainian billionaire Max Polykov, first sell off his share in the company.

Raytheon & Northrop Grumman successfully complete the second flight of a hypersonic missile prototype

10:04 am

Raytheon and Northrop Grumman, working in partnership, have successfully flown a hypersonic missile prototype for the second time in eleven months.

For the latest test, the HAWC prototype was carried under the wing of an aircraft and flown to high altitude, where it was released. A solid rocket booster then accelerated the vehicle to supersonic speed and a scramjet ignited. An engine without moving parts, a scramjet uses its forward motion to compress the incoming air into a shockwave that burns with fuel, producing enough thrust to propel the missile to over five times the speed of sound.

The latest prototype had only minor modifications from the previous flight and met all of its objectives. The data recovered by telemetry will be used to improve the digital models using artificial intelligence, machine learning, and big data, which will increase the efficiency and performance as the weapon concept comes closer to practical deployment.

As this is a military project, not many details about the prototype were released, such as its size, speed, design.etc. One shouldn’t even trust the illustrations of the missile, provided by Northrop Grumman. Each shows the missile with a rounded lifting body shape on its bottom side, likely to protect and guide it on its re-entry, but there is no guarantee the illustrations’ shape matches that of the real missile.

Maritime Launch Services signs land lease for its Nova Scotia spaceport

9:54 am

Capitalism in space: Maritime Launch Services yesterday obtained a 20-year land lease for its Nova Scotia spaceport from the province of Nova Scotia.

The lease covers 334.5 acres, and is renewable for an additional 20 years.

Unlike other spaceports, Maritime isn’t merely providing a launch site for rocket companies. Instead the company will also launch smallsats itself, using a Ukrainian-built rocket dubbed the Cyclone-4M. Initially the plan was to fly all launches in this manner, but the invasion of the Ukraine by Russia has caused Maritime to look for other launch providers as well.

Starship gets its first communications satellite customer

9:38 am

Capitalism in space: Sky Perfect JSAT, a Japanese satellite communications company, today awarded SpaceX a launch contract using its giant Starship/Superheavy rocket to put its Superbird-9 communications satellite into orbit in 2024.

Superbird-9 will be launched by SpaceX’s Starship launch vehicle in 2024 to geosynchronous transfer orbit. SpaceX’s Starship is a fully reusable transportation system that will be the world’s most powerful launch vehicle. SKY Perfect JSAT and SpaceX will continue to work together ahead of the launch of Superbird-9 Satellite.

Sky Perfect is the first communications satellite company to choose Starship for a satellite launch. It is however the rocket’s fourth signed customer. Japanese billionaire Yusaku Maezawa made a deal in 2018 for a flight around the Moon, while NASA chose Starship in 2021 as the manned lunar lander in its Artemis program. UPDATE: SpaceX also has a second private manned customer, Jared Isaacman, whose present deal with SpaceX calls for two Dragon flights followed by a Starship flight.

Sky Perfect is not a new company, with sixteen satellites already in orbit providing communications, broadband, and entertainment to Japan and the Far East. It likely made this deal because it got a very good launch price, with options to back out if the rocket’s on-going development gets delayed by too much. It also made the deal because it helps to solidify Starship’s future, something Sky Perfect probably sees as a win considering the significant reduction of launch costs expected from Starship/Superheavy.

A “What the heck!?” crater on Mars

3:16 pm

A
Click for full image.

Today’s cool image falls into what I call my “What the heck?” category. The photo to the right, cropped and reduced to post here, was taken on May 31, 2022 by the high resolution camera on Mars Reconnaissance Orbiter. It was also picked by the science team as that camera’s picture of the day on July 12, 2022. From the caption:

This seems to belong to a class of craters in the Cerberus Plains that was flooded by lava, which was subsequently uplifted and fractured by an unknown process. This class of filled, uplifted and fractured craters is informally called “the waffle.” A combination of volcanic and periglacial processes seems possible.

In other words, the scientists only have a vague idea what created the broken up floor of this crater. For example, why did only the material in the interior of the crater get uplifted and fractured? Did this uplift occur before, during, or after the lava event?

The overview map below tells us a little about where that lava came from, and when.

Russian spacewalk ends earlier due to spacesuit power problem

9:34 am

A Russian spacewalk yesterday to continue the configuration of Europe’s robot arm for the Russian half of ISS was cut short after four hours when the power system in Oleg Artemyev’s spacesuit begin producing unexpected “voltage fluctuations.”

“I have a message, voltage low,” Artemyev radioed Russian ground controllers around 12 p.m. EDT (1600 GMT). An engineer at Russia’s mission control center near Moscow warned Artemyev he would lose communications if his suit ran out of power.

Russian flight director Vladimir Solovyov then jumped on the line to tell Artemyev to head back to the safety of the airlock. “Oleg, this is Solovyov,” he said. “Drop everything and start going back (to the airlock) right away. Oleg, go back and connect to station power.”

This problem occurred about two hours into the spacewalk. The second astronaut, Denis Matveev, continued working at the robot arm for another two hours before mission control ordered him to end the walk early.

According to Russian officials, Artemyev was never in any danger, though the urgency in which he was ordered to come inside suggests otherwise. According to another news report, a power loss could have also shut down the spacesuit’s “pumps and the fan.”

Get above 30 degrees latitude on Mars and you can find ice everywhere

1:23 pm

Global overview of Mars' ice features

Glacial features inside a Mars crater
Click for full image.

Today’s cool image provides further proof that there is ample near surface ice almost anywhere on Mars once you get above 30 degrees latitude, in either the northern or southern hemispheres. The photo to the right, rotated, cropped, reduced, and annotated to post here, was taken on May 26, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the interior slope of an unnamed 15-mile-wide crater that sits inside the much larger 185-mile-wide Newton crater, located in the cratered southern highlands of Mars.

The black cross on the global map of Mars above marks the location of this crater.

The photo was taken as part of the routine monitoring planetary scientists are doing of the gullies that flow down this crater’s interior rim, a monitoring program that goes back to 2007. It is thought that those gullies might be created by seasonal frost, either water ice or dry ice, that causes erosion.

What struck me about the photo however was the glacial features on the floor of the crater. Near the bottom of the interior slope those features look broken up, as if the pressure from above pushed the ice sheets apart. Farther from the interior slope the features more resemble a typical glacial flow, slowly inching downward toward the crater’s low spot. All these glacial features also lend weight to the theory that water ice somehow caused or contributed to the formation of those gullies.

The global map above shows that this crater, while well within the 30 to 60 degrees mid-latitude band where many Martian glaciers are found, is also far from the many regions on Mars that scientists have mapped as having high concentrations of glaciers. And yet, the glacial features are here as well.

Near surface ice will not be found at every spot on Mars. However, once you get above 30 degrees latitude, the evidence increasingly suggests that you won’t have to go far or dig down deep to find it.

A detailed description of Rocket Lab’s private Venus mission

10:00 am

Planned insertion of Rocket Lab's probe into Venus's atmosphere
Click for full figure.

Capitalism in space: In partnership with scientists at MIT, the Planetary Science Institute, and others, Rocket Lab engineers this week published a detailed description of the company’s planned privately funded mission to Venus, presently targeting a launch in May 2023.

From the paper’s abstract:

The Rocket Lab mission to Venus is a small direct entry probe planned for baseline launch in May 2023 with accommodation for a single ~1 kg instrument. A backup launch window is available in January 2025. The probe mission will spend about 5 min in the Venus cloud layers at 48–60 km altitude above the surface and collect in situ measurements. We have chosen a low-mass, low-cost autofluorescing nephelometer to search for organic molecules in the cloud particles and constrain the particle composition.

The figure above is figure 6 from the paper. It shows the probe’s planned path through Venus’s atmosphere. If the mission launches in May ’23 the probe would enter the atmosphere in October ’23.

Samples from Ryugu prove the truly delicate and long-lived nature of the rubble-pile asteroid

9:27 am

Two new studies of samples brought back from the rubble-pile asteroid Ryugu by the Japanese probe Hayabusa-2 have found that the asteroid not only was never heated above 86 degrees Fahrenheit, it also contained dust grains older than the solar system itself.

The evidence from the first study, completed by Japanese scientists, suggested that:

  • 1.Asteroid Ryugu accreted some components that originated in the outer Solar System and contained abundant water and organics. The asteroid then traveled to the inner Solar System.
  • 2.Organics associated with coarse-grained phyllosilicates may serve as one of the potential sources of water and organics to the Earth.

The second study, using samples provided to American scientists, found two tiny dust grains that must have come from the material that existed before the formation of our solar system.

The team detected all the previously known types of presolar grains—including one surprise, a silicate that is easily destroyed by chemical processing that is expected to have occurred on the asteroid’s parent body. It was found in a less-chemically-altered fragment that likely shielded it from such activity.

This is not the first discovery of presolar grains, but their delicate existence in Ryugu confirms the conclusions of the first study, that Ryugu had to have formed in the outer solar system and then migrated inward over eons.

The second study also reviewed the make-up of the sample and concluded that Ryugu appears to most closely match the family of carbonaceous Ivuna-type (CI) chondrites, thought to be among the most primitive asteroids known, of which very few have been studied because of they rarely survive the journey through the Earth’s atmosphere.

Astrobotic makes bid to buy assets of bankrupt Masten

9:02 am

Capitalism in space: Astrobotic, a startup focused on building lunar and planetary unmanned landers, has now made a formal bid to buy the remaining assets of Masten Space Systems, which had also been a startup focused on planetary missions but recently went bankrupt.

In a filing with the U.S. Bankruptcy Court for Delaware Aug. 14, Masten said it received a “stalking horse” bid of $4.2 million for Masten’s assets, including a SpaceX launch credit worth $14 million, from Astrobotic. The agreement, in effect, sets a minimum price for the sale of those assets but does not prevent Masten from seeking higher bids through an auction process that runs through early September.

The agreement appears to supersede an earlier agreement between Masten and a third lunar lander company, Intuitive Machines, included in Masten’s Chapter 11 filing July 28. That agreement covered the SpaceX launch credits alone and Masten did not disclose the value of it in its original filing.

Masten’s long term specialty has been vertical take-off and landing, something it has successfully done for the last several years on suborbital flights. This technology would be of great value to both Astrobotic and Intuitive Machines in developing their own first lunar landers.

SLS arrives at launchpad

8:44 am

The Space Launch System rocket (SLS) that will fly on NASA’s first test launch of this rocket on August 29, 2022 has finally arrived at its launchpad, seven years late and about $20 billion overbudget.

In the coming days, engineers and technicians will configure systems at the pad for launch, which is currently targeted for no earlier than Aug. 29 at 8:33 a.m. (two hour launch window). Teams have worked to refine operations and procedures and have incorporated lessons learned from the wet dress rehearsal test campaign and have updated the launch timeline accordingly.

The rollout from the Vehicle Assembly Building took ten hours.

InSight’s power status continues to hold steady on Mars

11:21 pm

InSight power status through August 14, 2022

According to a new status update posted today by the science team, the power status for the Mars InSight lander continues to hold steady.

The graph to the right adds the new data, showing that the daily watt hours of power produced each day continues to hold at 400, while the dust in the atmosphere continues to drop towards its normal level of between 0.6 and 0.7 tau during the non-dust seasons.

These new numbers appear to be generally good news. Even though the dust continues to settle out of the atmosphere, it does not appear to be adding dust on the solar panels that would reduce their capability to generate power. Though the science team had predicted that the power levels would cause the mission to end sometime in August, at 400 watts per hour InSight has apparently continued to generate enough electricity to keep its seismometer running for at least another week.

Jupiter’s internal structure, based on Juno data

12:05 pm

Jupiter's internal structure
Click for original figure.

Scientists using Juno data of Jupiter’s magnetic field, combined with computer modeling, have now produced a rough map of the gas giant’s internal structure.

The image to the right, figure 2, of their paper, shows that structure. I have annotated the figure to provide some sense of scale. The bold violet line indicates their conclusions about the size of the dynamo that drives Jupiter’s powerful magnetic field, comprising more than 80 percent of the planet’s internal diameter. From the caption:

The gray area depicts the core (0.2 RJ) and the possible dilute core region. The violet area between the dotted lines (0.68 and 0.84 RJ) depicts the [hydrogen-helium] phase separated layer. The top dotted line at 0.95 RJ depicts the depth where the jets decay down to the minimum. The arrows represent possible convection area with unknown origin depth.

While this is a good first hypothesis based on the available data, that data remains quite sparse and uncertain. Thus, the conclusions here must be taken with a great deal of skepticism.

More evidence of recent active volcanism on Venus

11:37 am

In a just published paper, scientists using archive data from the Magellan radar orbiter that circled Venus from 1990 to 1994, combined with data from Europe’s Venus Express that orbited from 2006 to 2015, have detected more evidence of recent volcanic activity in a canyon dubbed Ganis Chasma located in a rift zone called Atla Regio.

From the paper’s conclusion:

The pattern of the radar emissivity in these regions is consistent with relatively young and unweathered materials. The transient IR-bright spots in these regions detected 20 years after Magellan, provide independent corroboration of active volcanism in Ganis Chasma since the 1990’s.

As a possible site of current tectonic and volcanic activity, Atla Regio represents one important science target for the upcoming missions to Venus.

There are presently four missions planned for Venus, Europe’s EnVision orbiter, NASA’s VERITAS and DAVINCI+ probes, and Russia’s Venera-D missoin. All will certainly take a closer look at this region to see if there is active volcanism going on there now.

Dust and clouds in the Martian atmosphere, as seen by UAE’s Al-Amal orbiter

11:18 am

Two new science papers have just been released detailing results from the Al-Amal (Hope) Mars orbiter that was designed and built by American universities for the United Arab Emirates (UAE).

Both papers used data obtained from the orbiter’s infrared spectrometer, dubbed the Emirates Mars Infrared Spectrometer (EMIRS).

Daily cloud cover changes on Mars
Figure 1 from paper. Click for full image.

First, the instrument tracked the daily changes in the planet’s cloud cover.

A prominent region of clouds that is commonly observed near the equator during Mars’ cold season—known as the aphelion cloud belt—was observed to reach a minimum near midday, with more clouds typically observed in both the morning and afternoon. Distinct differences were found in clouds observed near volcanoes, which tended to reach a minimum before local noon and increase throughout the afternoon.

The figure to the right shows this. In the morning and afternoon (LTST’s 7 and 17), there is a high concentration of clouds in the equatorial region above the Tharsis Bulge where the highest Martian volcanoes are located. During the middle of the day (LTSTs 11 and 13) this cloud cover largely dissipates, with a corresponding increase in cloud cover in Hellas Basin, in the southern hemisphere.

The second paper took a more general look at the data, including the change in temperature depending on elevation as well as dust and water content during the Martian northern spring and summer. From the abstract:

China’s radar ship finally docks in Sri Lanka

9:00 am

Despite objections by India and an initial refusal by the Sri Lanka government to allow a Chinese military communications/radar ship to dock at one of Sri Lanka’s ports, the ship was finally allowed to dock yesterday.

Sri Lanka, which needs the support of both India and China as it struggles with its worst economic crisis in decades, initially granted the ship permission for a five-day replenishment stay in Hambantota, from Aug. 11.

It later asked China to delay the vessel’s arrival, citing the need for more consultations.

Yuan Wang 5 will now berth for only three days to stock up on fuel, food and other essentials, said an official at the port who declined to be identified as he is not authorised to speak to the media.

The ship is used by China to track satellites, rockets, and missiles, both its own and other nations.

Sri Lanka is caught between a rock and a hard place. The country is bankrupt, its citizens facing starvation due to the previous government’s imposition of numerous green environmental policies that destroyed its agriculture industry. It has also taken aid from both India (providing military hardware) and China (which built the port and holds a 99-year lease to operate it), and neither looks kindly at the other.

Merger deal between Italian orbital tug company D-Orbit and Breeze canceled

8:52 am

Capitalism in space: The merger deal between the Italian orbital tug company D-Orbit and the special purpose acquisition investment company (SPAC) Breeze has been canceled.

The Italian company had hoped to raise $185 million from the deal to expand staff and accelerate investments in ION Satellite Carrier, its orbital transfer vehicle (OTV) that completed its first commercial mission in late 2020.

However, “financial markets have changed substantially” since the deal was announced Jan. 27, Breeze CEO Douglas Ramsey said, amid rising interest rates, soaring inflation, and an ongoing war in Ukraine. “As we look ahead, we remain focused on identifying another value creating opportunity for Breeze shareholders,” Ramsey added.

A SPAC is a shell company designed solely to gather investment capital that is then used to either buy or merge with another company. In the process the company that is taken over goes public, its stock available on the stock market for trade. There have been a number of such takeovers in the space sector in the past few years, but most have turned out poorly for the investors in those SPACs, as noted in the article:

Of the nine space companies that went public through SPAC mergers in 2021, only Rocket Lab’s shares finished the year trading above their price when the merger closed. [Ed: both Virgin Galactic and Astra are examples of these failures.]

Demand for new SPAC deals has also been waning amid declining investor appetite for risk and increasing regulatory scrutiny over how these blank check firms operate. More than 40 SPAC mergers have been canceled so far this year, reported Bloomberg.

To put it more bluntly, investors have found these SPACs to be poor investments, and are bailing from them. This is likely what happened at Breeze, thus forcing the cancellation of the deal with D-Orbit.

Cones south of Starship’s prime landing sites on Mars

Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 7, 2022 by the high resolution camera on Mars Reconnaissnace Orbiter (MRO). It shows what the scientists have labeled as “Cones in Phlegra.”

Cones such as these are one of the prime geological mysteries of Mars’ northern lowland plains. Scientists do not know yet whether they are either mud or lava volcanoes, or even if they are sedimentary mesas that resisted subsequent erosion. In fact, it was hoped by some American scientists that the Chinese would send its Zhurong rover north towards a nearby cone to find out, but alas, the Chinese decided to head south instead.

Zhurong however was on the other side of Mars. The overview map below shows us where these cones are located.

Close-up of distant cliff face
Click for full image.

Two cool images arrived today from Curiosity, as it is about to enter the Martian canyon of Gediz Vallis. The mosaic above, cropped, reduced, and annotated to post here, was assembled from photos taken by the rover’s right navigation camera on August 15, 2022. The photo to the right, cropped and reduced to post here, was taken the same day by the rover’s Chemistry camera, normally designed to take very close-up pictures of nearby features. In this case the science team aimed it at a distant cliff face, marked by the arrow in the panorama above, to get a preview of some of the many layers in that mesa.

And has become quite expected from Mars, the number and types and variety of layers is astonishing. The layer that forms the flat bright area at the center of this image is what scientists have dubbed “the marker layer”, since they have found it at similar elevations in many places on the flanks of Mount Sharp. (See the annotated overview map from a post last week.)

Curiosity’s planned route is to head to the right of this mesa, circling around it to get into the upper reaches of Gediz Vallis. First however engineers are going to have to figure out how to get the rover past the somewhat large scattered rocks on the ground directly ahead, without further damaging Curiosity’s already tattered wheels. At first glance there does not appear to be any clear path.

Russia to launch Tunisian astronaut to ISS

9:38 am

As part of an agreement between the two nations, Russia yesterday announced that it will fly a Tunisian woman to ISS in 2024.

On August 13, Women’s Day in Tunisia, eight women candidates for a space flight were presented. They are currently undergoing medical examination. Six of them will go to Russia for the final stage of pre-qualification to choose two best candidates: one will be a member of the main crew, the other one – of the standby crew.

No longer able to make money selling the spare seats on Soyuz to NASA, and apparently not getting much interest from the private sector inside or outside of Russia to buy these seats, the Putin government is now using them for international diplomacy, just as it did during the Soviet era.

Russia unveils small model of its proposed space station

9:32 am

Tabletop Model of Russian Space Station

The Russian space agency Roscosmos today unveiled a small tabletop model of the independent Russian space station it proposes to build that will replace its portion on ISS.

The picture to the right shows that model. It shows four large modules, a second docking hub, and a Russian manned Federatsiya (“Federation” in English) capsule (intended to replace Soyuz) docked to the nearest port.

Roskosmos said in a statement that the new space station would be launched in two phases, without giving dates. The first phase would see a four-module space station start operating. That would later be followed by a further two modules and a service platform, it said. That would be enough, when completed, to accommodate up to four cosmonauts as well as scientific equipment.

Roskosmos has said the new station would afford Russian cosmonauts a much wider view of the Earth for monitoring purposes than they enjoy in their current segment. Although designs for some of the new station already exist, design work is still underway on other segments.

Russian state media have suggested that the launch of the first stage is planned for 2025-26 and no later than 2030. Launch of the second and final stage is planned for 2030-35, they have reported.

Russia officials have also said that it will stick with its partnership at ISS until this new station has begun operations.

It will be very revealing how successful Russia is at meeting this timetable. For the past thirty years, since the fall of the Soviet Union and the advent of international cooperation at ISS, its aerospace sector has routinely failed to meet any schedule at all, promising a lot but never delivering, or delivering literally decades late. (For example, Federatsiya has been under development for almost a decade, with no apparent progress.) Forced to go it alone, and in competition with the rest of the world, that sector, now controlled and owned by the government (like the Soviet days), might finally have some incentive to produce.

Or not. The corruption that permeates Russia’s government is deep and widespread. It is entirely possible that a large percentage of the money budgeted for this project ends up in the pockets of its managers instead of used to build anything.

We shall have to wait and see.

Biden administration to formulate new regulations governing in-space commercial activities

We’re here to help you: The Biden administration has now officially announced its plans to formulate new regulations governing in-space commercial activities, such as satellite repair, orbital refueling stations, and removal of space junk, as part of a space strategy workshop statement released last week by the FCC.

The new White House initiative is a follow-on effort [to one started during the Trump administration], aimed at fleshing out the domestic rules, and possibly future regulations, for “non-traditional” space activities that today either fall between jurisdictional cracks or simply are not covered by current law, according to a US government source involved.

Another thrust of the Biden administration effort is to get in front of the governance issues in order to shape future global norms and rules, including for military activities — ahead of China, which also is seeking to be a leader in how humankind expands its reach to the stars.

Kamala Harris announced this new regulatory effort, outlined in this strategy document [pdf], and added that it will be led by the National Space Council, despite the fact that the FCC scooped her by a full week in announcing it. This quote below from her speech announcing this initiative also illustrated her empty-headed, cliche-ridden mentality:

“We will do this work to make sure our nation remains a role model for the responsible use of space,” Harris said in a speech during a visit to the Chabot Space & Science Center in Oakland, Calif. noting that the US “must write new rules to provide the clarity” needed by government and industry for 21st century space operations.

“We must think about where we now stand and where we must go,” she said. “The opportunity of space must guide our work in the 21st century. to do so, must deepen our partnerships with the private sector.”

Despite the vapid content of Harris’s speech, make no mistake she and the federal bureaucracy that is dominated and controlled by the Democratic Party knows exactly where it wants things to go: It wants power and control, and is very unhappy that in the past five years private enterprise has wrested that power and control from it in space. These new regulations will be shaped entirely with the goal of squelching the freedom of private companies so that the government runs things again.
