Astronauts complete installation of 1st set of new solar panels on ISS

8:47 am

Astronauts yesterday successfully completed the installation of the first set of new solar panels on ISS, completing the work they could not do on a first spacewalk because of issues with one of the astronaut’s spacesuits.

The new panels are deployed on top of the old panels. Though smaller, they are more efficient, so they actually produce more energy total.

The IROSAs [acronym for the new panels] will be installed on top of six of the station’s existing solar arrays, which will allow the IROSAs to utilize the same sun-tracking motors and be connected into the same electrical system as the current arrays.

With the IROSAs being around 30% efficient, compared to the 14% efficiency of the original arrays, the IROSAs will generate roughly the same amount of power as the originals despite being only half their size. Each IROSA will produce 20kW of additional power, for a total of 120kW across all six arrays.

However, because the IROSAs are smaller, they will not completely cover the half of the six [old panels] they’ll be installed over. Instead, portions of the original arrays will still be power positive. The unshadowed portions of the original arrays will continue to produce 95kW as a result, making for a combined total of 215kW of power available to the ISS — an increase of nearly a third compared with the outpost’s current levels.

The set installed yesterday was the first of six new panels to be installed, replacing all of the old panels.

First attempts to fix Hubble fail

9:43 am

An attempt to switch the Hubble Space Telescope to a different backup computer module in order to bypass a broken unit failed last week, leaving the telescope in safe mode.

A payload computer on Hubble stopped working June 13, the agency said in a June 16 statement. Engineers speculated that the computer, used to manage operations of Hubble’s science instruments, malfunctioned because of a degrading memory module, putting the instruments into a safe mode.

The agency said at the time that it would switch of a backup memory module that day and, after about a day of testing, restart the instruments and resume science observations.

However, in a June 18 statement, NASA said those efforts to switch to a backup memory module failed because “the command to initiate the backup module failed to complete.” An attempt to restore the computer with both the original memory module and the backup unit also failed.

While the engineers at the Space Telescope Science Institute, that operates Hubble, have expressed confidence they can overcome these issues, the failures this week are truly troublesome. We may truly be facing the end of the telescope,

A confused river of ice on Mars

A river of ice on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on March 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what MRO’s science team labeled a “Landform in Source Region of Harmakhis Vallis.”

They are being very correct and careful with that label. The landform here is quite clearly reminiscent of a glacier, but because they don’t yet have confirmation of its watery nature, as good scientists they can’t call it that.

I however am a mere journalist, so I am free to speculate more wildly. Sure looks like glaciers to me, the ice flowing downhill from the left to the right and flowing around that central mound.

The overview map below gives a wider context, but also makes the behavior of the glaciers here far more puzzling.

Japanese scientists complete inventory of Ryugu asteroid samples

9:00 am

In a press conference yesterday the Japanese space agency JAXA announced that scientists have completed their inventory of the samples brought back from the asteroid Ryugu by the Hayabusa-2 spacecraft, and are now ready to begin distributing those samples to scientists around the world for more detailed research.

JAXA has cataloged the soil samples brought back by Hayabusa 2 last December, by size, color and shape. From now, 269 researchers from 14 countries, including Japan and the United States, will conduct an in-depth analysis of the soil’s structures and components over the course of about a year.

As expected, the inventory found the samples had a large amount of hydrogen, oxygen, and carbon atoms. Even before Hayabusa-2’s arrival, Ryugu had been catalogued as a “hydrated” asteroid, which means it was thought to contain a lot of hydrogen and oxygen, the basic elements of water. The inventory has now confirmed this.

Japan passes law protecting property rights in space

8:42 am

Japan’s legislature on June 15th approved a new law designed to protect the ownership of the resources private entities extract for profit in space.

Japan’s legislation is similar to provisions in the Commercial Space Launch Competitiveness Act, passed by the U.S. Congress and signed into law by President Obama in 2015. That law grants U.S. companies rights to resources that they extract, but not property rights to celestial bodies, which would run afoul of the Outer Space Treaty. Luxembourg and the United Arab Emirates have since passed similar legislation.

All four countries are signatories of the Artemis Accords, which endorses the ability to extract and use space resources. “The Signatories affirm that the extraction of space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty, and that contracts and other legal instruments relating to space resources should be consistent with that Treaty,” the accords state.

Both Russia and China oppose such legislation, as well as the Artemis Accords, which have now been signed by eleven countries.

What this growing alignment of opposing sides means for future space operations by private companies is unclear, though it suggests these two countries will not honor those private property rights, which in turn suggests this legal disagreement is eventually going to lead to physical conflict in space.

China and Russia outline long term plans for building joint lunar base

11:08 am

China/Russian Lunar base roadmap

The governments of China and Russia yesterday announced their long term roadmap for building a joint manned lunar base on the Moon, what they have labeled the International Lunar Research Station (ILRS).

The graphic to the right, rearranged by me from the PowerPoint slides released by the two governments, shows the overall plan.

The first phase, starting now and running through ’25, will involve six already planned unmanned missions by both countries, three each. Of the three Chinese unmanned missions, Chang’e-4, Chang’e-6, and Chang’e-7, the first is already operating on the Moon, as it includes the Yutu-2 rover. Based on China’s recent track record, it would be reasonable to expect the other two Chang’e missions to fly as planned.

Of the three Russian missions, Luna 25 is scheduled to launch later this year, making it the first all-Russian-built planetary mission in years and the first back to the Moon since the 1970s. The other two Russian probes are supposedly under development, but based on Russia’s recent track record in the past two decades for promised space projects, we have no guarantee they will fly as scheduled, or even fly at all.

The second phase, running from ’26 to ’35, will begin construction, though the details are vague.

The third phase, when China & Russia say they will begin full operations in ’36, is even more vague, merely stating the objective of human “lunar research and exploration”.

The pace matches well with the typically slow pace of these kind of government programs. It not only matches with the pace that China has shown in its entire manned program, with manned missions sometimes separated by years, it also matches the sluggish long term roadmap that NASA has put forth for its own Artemis program on the Moon. It also fits with Russia’s recent pattern, which is to repeatedly announce big projects and goals, with little actual execution to follow.

At first glance the plan suggests that we are in a new space race between the United States and its national partners in the capitalist west and the authoritarian governments of China and Russia. That may be so, but I think the real race will be between the government programs in China, Russia, and the U.S. and the efforts by private commercial companies aiming to make profits in space. And if you ask me to bet on who will get more accomplished faster for less money, I will hands down put my money on those private companies. The more profit they make, the faster they will push to move forward, and will quickly leave these sedate government programs in the dust.

Russia announces it is shifting its manned operations on ISS to yearlong missions

10:35 am

According to Dmitry Rogozin, head of Roscosmos, Russia is changing the standard length of a crew stay at ISS from six months to a full year, beginning with the flight in which the crew will help film a commercial movie on ISS in October.

Then-Head of the Gagarin Cosmonaut Training Center Pavel Vlasov earlier said that two members of the Soyuz MS-18 spacecraft, Pyotr Dubrov and Mark Vande Hei, would stay in orbit longer than six months to help shoot a film Vyzov (Challenge). He also said that crew commander Oleg Novitsky would return to Earth in October aboard the Soyuz MS-18’s descend capsule together with the participants of the Soyuz MS-19 spacecraft’s flight (actress Yulia Peresild and film director Klim Shipenko who would be engaged in the film). Two crewmembers, cosmonaut Dubrov and NASA astronaut Vande Hei, would remain in orbit and return to Earth aboard the Soyuz MS-19 spaceship, he said.

Gaining experience at missions a year or longer, something only the Russians have accomplished, makes sense if one plans to send astronauts to Mars. I suspect however there is a second more practical reason for this change: It will free up seats on Soyuz to sell for commercial tourist flights. Russia clearly wants to compete successfully with the new American commercial manned flights that SpaceX and Axiom will be flying. This change gives them that opportunity.

Rogozin himself likely has personal financial motives. He is a co-producer on that movie, and likely will also pocket personally some of the profits from future tourist flights.

SpaceX confirms it is shifting to Starship orbital test flights

10:24 am

Capitalism in space: By shifting both the 15th and 16th Starship prototypes to its garden at Boca Chica of retired spacecraft, SpaceX has essentially confirmed that it has shifted operations there from short test hops to Starship orbital test flights.

Built as the first of several planned backups to Starship SN15, which debuted a number of significant upgrades in April and May, it appears that Starship serial number 16 (SN16) has been retired to a display stand after its only sibling became the first full-size prototype to successfully survive a launch and landing on May 5th. SN16 actually reached its full height before SN15 lifted off and was more or less complete by May 10th. Since then, the prototype has remaining more or less untouched, seemingly waiting for SpaceX to decide its fate in lieu of Starship SN15’s major success.

Ultimately, with SN16 now sitting side by side with SN15 at what will likely become a sort of open-air SpaceX museum, it appears that the company has made up its mind.

In other words, prototype #16, though built and ready to fly, will likely never do so. Instead, the company is focusing its operations on preparing for the first orbital test flights using Starship prototype #20 stacked on top of a Superheavy, with the first flight planned to circle three-quarters of the globe to land in the Pacific northeast of Hawaii.

Since neither #20 nor its Superheavy are fully assembled, that flight will likely not occur in July, as SpaceX had initially suggested as its targeted launch date. However, with all work now focused on that orbital test flight, it is almost certain they will attempt it before the year is out.

The big question is whether Starship’s first orbital flight will beat out SLS’s first orbital flight, presently scheduled for November but expected to be delayed.

Spacesuit issues prevent spacewalk from completing new ISS solar panels installation

10:12 am

Astronauts on ISS yesterday were unable to complete the installation of a new solar panel on ISS because the suit of one astronaut began experiencing technical problems.

First, a sensor in the suit’s sublimator — which provides pressure — registered a spike. Shortly thereafter, the Display and Control Module (DCM) in his suit malfunctioned, necessitating an immediate return to the Quest Airlock to connect back to Station umbilicals to attempt a restart of the unit.

The “warm restart” of the DCM meant that Shane [Kimbrough]’s suit momentarily lost its cooling and CO2 scrubbing capabilities; however, this is an acceptable condition, per EVA procedures, when attempting to “warm restart” a DCM. A failure to restart the unit would have meant a premature end to the EVA.

The restart was successful, and ground teams sent Shane back out to Thomas while managers and engineers continued to discuss the sublimator issue — which itself could have also stop the EVA early. Fortunately, through a series of suit configuration tests, ground teams were able to determine that the sublimator was functioning properly and that a faulty sensor likely triggered an erroneous pressure increase reading.

The time lost in fixing these issues however prevented the astronauts from finishing their work. The new solar panel was attached, but not unrolled into its full deployed configuration. The astronauts also were unable to plug the new panel into the station’s electrical system.

Engineers are now assessing the situation in order to plan a follow-up spacewalk.

Manned Shenzhou capsule docks with Tianhe

9:53 am

China’s manned Shenzhou capsule early this morning successfully docked with the Tianhe module of that nation’s new space station.

The three astronauts on board will spend the next three months doing work in connection with the assembly of that station. Though this was the first Chinese manned mission in five years, the pace is expected to pick up in the next year.

Eight more launches will be required to finish construction of the space station, Chinese officials have said. Two will loft “lab modules” that will attach to Tianhe, forming the final T-shaped station. The assembly phase, which is expected to wrap up by the end of 2022, will also include three more cargo launches and three additional crewed missions.

SpaceX successfully launches GPS satellite for Space Force

9:40 am

Capitalism in space: SpaceX today successfully launched a new GPS satellite for the Space Force.

As I post this the second stage has not yet deployed the satellite, though it is in orbit. UPDATE: As expected the satellite has been successfully deployed into its proper orbit.

This was the first Space Force launch using a reused Falcon 9 first stage. The stage, making its second flight, successfully landed on the drone ship, broadcasting the absolutely best video ever of such a landing, with the cameras on both the stage and the drone ship working without distortion throughout the landing to touchdown. The live stream is embedded below the fold, with that landing at 8:34 minutes after launch.

The two fairing halves are new but their pick up method for reuse has been streamlined:

For this mission, a new vessel has joined SpaceX’s oceangoing recovery fleet. HOS Briarwood will attempt to recover Falcon 9’s payload fairing halves after they splash down in the Atlantic Ocean. Similar in size to Shelia Bordelon, the previous temporary fairing recovery vessel, HOS Briarwood can be booked as a “flotel” and features an enormous crane, along with seemingly just enough deck space to support two recovered fairing halves.

Apparently, allowing the halves to land directly on the ocean surface and act as floating boat hulls until the ship can pick them up on a single ship, using a crane, is now the recovery method. There is also the hint that SpaceX might also be planning to sell tickets on this ship for people who wish a vacation watching that fairing recovery operation.

The leaders in the 2021 launch race:

19 SpaceX
17 China
8 Russia
3 Northrop Grumman

The U.S. now leads China 27 to 17 in the national rankings. Note: The average number of American launches per year during the 21st century (from 2000 to 2020) was 22. The U.S. has now topped that average by five launches, and the year is not even half over.

Chinese astronauts successfully launched into space

6:55 pm

The new colonial movement: Using its Long March 2F rocket China tonight (June 17th in China) successfully launched three astronauts into orbit on their Shenzhou manned capsule for a planned three month mission to the first module of their new space station.

The most recent update as I post this:

Chinese mission control has confirmed today’s launch was a success, placing the Shenzhou 12 capsule into an orbit ranging in altitude between 120 miles (220 kilometers) and 208 miles (335 kilometers). Docking with the Tianhe core module is expected in approximately six hours. The rendezvous will be fully automated.

No word on where the four strap-on boosters and core stage landed within interior China.

The leaders in the 2021 launch race:

18 SpaceX
17 China
8 Russia
3 Northrop Grumman

The U.S. still leads China 26 to 17 in the national rankings, and will add to that lead if a planned SpaceX launch tomorrow goes as planned.

Hubble in safe mode due to computer problem

1:47 pm

A computer failure on June 13th put the Hubble Space Telescope in safe mode, with engineers hoping to have the problem resolved and the telescope back in operation by tomorrow.

NASA is working to resolve an issue with the payload computer on the Hubble Space Telescope. The computer halted on Sunday, June 13, shortly after 4 p.m. EDT. After analyzing the data, the Hubble operations team is investigating whether a degrading memory module led to the computer halt. The team is preparing to switch to one of several backup modules on Wednesday, June 16. The computer will then be allowed to run for approximately one day to verify that the problem has been solved. The team would then restart all science instruments and return the telescope to normal science operations.

The unit itself, while built in the 1980s, was only launched to Hubble in 2009 as part of the last shuttle repair mission.

FAA, local Texas DA, and environmental group out to get SpaceX and Starship

10:16 am

Two news articles today suggest that a number of government officials, environmental groups, and some news media are beginning to team up to damage SpaceX and hinder its ability to succeed.

First we have this Verge article, aimed at suggesting that SpaceX violated its launch license and ignored FAA warnings not to launch during a December 9th test flight of the eighth Starship prototype.

Minutes before liftoff, Elon Musk’s SpaceX ignored at least two warnings from the Federal Aviation Administration that launching its first high-altitude Starship prototype last December would violate the company’s launch license, confidential documents and letters obtained by The Verge show. And while SpaceX was under investigation, it told the FAA that the agency’s software was a “source of frustration” that has been “shown to be inaccurate at times or overly conservative,” according to the documents.

The article generally takes the side of the FAA, suggesting that SpaceX was lax and nonchalant about the risks relating to weather and launch conditions, and proceeded with its launch even though FAA officials thought it unsafe. It also quotes Wayne Monteith, the head of the FAA’s space division, blasting SpaceX for showing “a concerning lack of operational control and process discipline that is inconsistent with a strong safety culture,” claiming that FAA software showed a risk to nearby buildings and homes should the rocket explode in the air.

However, buried far down in the article it also notes,

Another smallsat startup announces plans to build its own orbital space tug

9:34 am

Capitalism in space: The smallsat launch startup Launcher announced yesterday that it in addition to developing its own rocket, it plans to build an orbital space tug that can be used both by it and on other smallsat satellites.

Launcher, which announced a $11.7 million funding round June 2, said its Orbiter tug will be able to carry up to 150 kilograms of payload, either in the form of 90 units worth of cubesat deployers or larger satellites using standard smallsat separation systems. Orbiter can also accommodate hosted payloads with power, communications, and other capabilities. Orbiter is equipped with a chemical propulsion system using ethylene and nitrous oxide propellants. The vehicle will initially provide 500 meters per second of delta-v, or change in velocity, but that can be increased by adding more propellant tanks.

Orbiter is intended for use on Launcher Light, the small launch vehicle the company is developing, with a first launch projected in 2024. However, Orbiter is also capable of flying on other launch vehicles using an ESPA Grande adapter ring. Orbiter’s first mission is scheduled for October 2022, when it will fly on a SpaceX Falcon 9 rideshare mission.

That makes about four companies, Launcher, Momentus, Spaceflight, and D-Orbit, building space tugs for use on smallsats. Some will be on board a Falcon 9 launch set for later this month.

Some Starlink units shut down if weather gets too hot

9:27 am

Capitalism in space: Some users of SpaceX’s Starlink internet dishes have found that the units shut down if the local weather gets too hot.

The units presently being distributed to customers are beta units, designed to test the system before SpaceX rolls out full commercial availability, so finding such issues is not unexpected. According to one engineer quoted at the link,

Engineers could change Dishy’s mechanical design to achieve better heat rejection, change the dish’s electrical components to expand its thermal operating window, or develop a feature that allows Dishy’s components to operate at reduced power to create less heat. He noted the latter two options would likely be taller orders. “If changes to Dishy’s mechanical design are insufficient to reject heat at a rate exceeding its ability to produce it, software changes will be required to make the system more thermally efficient,” Keiter said. “But if speed limiting and system optimization can’t fix the issue, it will require a significant hardware revision for the commercial launch.”

“Since they’ve got a lot of custom silicon in there—likely the limiting factor—the turnaround time on this would be very slow,” he added. “They could resort to some form of active heat removal like fans or thermoelectric cooling, but then they burn a ton of power which would make Dishy even more power hungry than it already is.”

“This is a really tricky engineering problem with some insanely tight constraints,” Keiter said. “The good news is that the team is pretty sharp.”

First manned mission to new Chinese space station to launch June 17th

9:19 am

The new colonial movement: China yesterday announced that the first manned mission to its new Chinese space station will launch tomorrow, June 17th, carrying three astronauts to the station’s Tianhe core module launched earlier this year.

One day before launch, China finally confirmed unofficial reports that it will launch the first crew to its new space station module, Tianhe, on June 17 Beijing Time (June 16 Eastern Daylight Time). It is China’s first human spaceflight launch in 5 years. The three men will stay aboard Tianhe for three months, the longest time in orbit for any Chinese crew.

During the three month mission the astronauts will do at least one spacewalk to likely deploy solar panels and other equipment preparing Tianhe for later modules.

The announcement also included statements by Russia that it has agreed to send Russian astronauts to the station at some point in the future.

No word on whether China will broadcast the launch live.

Capitalism in space: Rocket Lab has won a contract to build two Mars smallsat planetary probe as part of a NASA project.

The project, led by the University of California, will have two probes dubbed Blue and Gold that will launch in 2024 on a Falcon Heavy rocket. The science goal is to place two spacecraft in Mars orbit to provide a more global look at is atmosphere. The financial goal is to show that smallsats built for less can do the same job as larger probes costing millions more.

Brazil signs Artemis Accords

9:04 am

Brazil on June 15th became the first South American country to sign the Artemis Accords, designed to bypass the limitations placed on property rights created by the Outer Space Treaty.

U.S. policy requires any nation that wishes to participate in its Artemis program to go back to the Moon to agree to the accords. Brazil is now the eleventh country to sign, joining Australia, Canada, Italy, Japan, Luxembourg, New Zealand, South Korea, the United Kingdom, the United Arab Emirates, Ukraine, and the United States.

Russia and China oppose the accords, which causes a problem for Russia as it desperately needs to partner with someone because it can’t on its own afford to build much. It is negotiating possible partnerships with China at its new space station as well as building a base on the Moon, but those agreements are not firm. And continues to send out feelers, including statements by Putin, calling for continuing cooperation with the U.S. in space.

Whether the Biden administration will make an exception for Russia in regards to the Artemis Accords remains unclear. That twelve countries have agreed to the accords however gives the U.S. greater leverage with those countries that have not yet signed.

Northrop Grumman launches three military satellites using Minotaur rocket

8:56 am

Early this morning Northrop Grumman successfully used a former Minuteman rocket repurposed as a commercial rocket dubbed Minotaur to launch three military reconnaissance satellites for the National Reconnaissance Office.

The rocket’s solid-fueled stages were in themselves amazingly old.

The 69-foot-tall (21-meter) rocket is based on leftover solid-fueled motors from the U.S. Air Force’s Minuteman missile program. Designers added two Orion solid rocket motors on top of the lower two stages of a Minuteman missile to turn the bomb carriers into satellite launchers.

The Minotaur 1 rocket’s M55A1 first stage motor was cast with solid propellant in 1966 by Thiokol, now part of Northrop Grumman. The SR19 second stage motor, produced by Aerojet, was filled with its solid propellant in 1983, according to a Northrop Grumman spokesperson.

The age of the first stage means it is likely the oldest rocket motor ever used on a space launch.

The leaders in the 2021 launch race:

The U.S. now leads China 26 to 16 in the national rankings.

Boxwork in the basement of Mars

Polygon ridges in Hellas Basin
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, shows what resembles closely what in Earth caves are called boxwork, polygonal ridges sticking out from the bedrock and usually indicating cracks filled with harder material that resist erosion.

Taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on March 23, 2021, what makes this boxwork especially interesting is its size and location. On Earth cave boxwork generally ranges from a few inches to a few feet across. Not only do these Martian ridges range from 100 feet to a half mile in length, they are located at the lowest point in Hellas Basin, the basement of Mars. In fact, this spot is as close as you can get to Mars’ Death Valley, as shown by the overview map below.

Russian astronaut fired for opposing filming of movie on ISS

9:22 am

Krikalev on the shuttle to ISS flight in 1998
Sergei Krikalev on the first ISS assembly flight
by the space shuttle Endeavour in 1998.

According to one new story today, Russian astronaut, Sergei Krikalev, 62, was fired from his position in senior management within Roscosmos for opposing its decision to film for profit the first feature film on ISS.

Krikalev did not say why he was against the film but his stance was backed by former colleagues who said that taking a passenger would delay a flight for a cosmonaut. Roscosmos denied that Krikalev had been fired.

Krikalev is one of Russia’s most celebrated astronauts. He was the first person to fly in space who was born after Sputnik, was the first Russian to fly on the space shuttle, and was the first Russian (along with an American) to enter ISS’s first module soon after launch. Overall he has spent more than 800 days in space.

He also became the last Soviet citizen, stranded on Mir when the Soviet Union fell in 1991. When he launched, he was a citizen of the U.S.S.R. When he finally returned, that country didn’t exist, and he was now a citizen of Russia.

I interviewed him extensively for my book, Leaving Earth, because he was fluent in English due to his flights on the shuttle. What I learned was that Krikalev was then and probably still is an ardent communist. On that Mir flight he refused to be filmed in a commercial for Coca-Cola, arranged by Roscosmos to make some money. There was no way he would allow himself to be recorded in such a crass for-profit manner. Thus, I am not surprised he now opposes using Russian space facilities for a commercial movie, for profit.

I also found him to be a very thoughtful and analytical man, which also probably explains his opposition to this quickly arranged commercial flight. The film company is partly owned by Dmitry Rogozin, head of Roscosmos, so there probably is some payoffs and corruption involved. It is also probably interfering with the Russian side of operations, as the story says Krikalev claims. These factors would cause Krikalev to speak his mind and argue against the flight, which likely angered Rogozin, who is apparently pocketing some cash from the film.

I suspect Krikalev is not fired, but has merely been sent to the doghouse for a short while. Roscosmos (and Rogozin) can’t afford the bad publicity of letting him go. It also needs his expertise in their operations.

Northrop Grumman’s Pegasus rocket launches military satellite

9:08 am

Early this morning Northrop Grumman’s Pegasus rocket successfully launched a military satellite under a program aimed at demonstrating a quick launch capability.

This was the first Pegasus launch since 2019, and only the fifth in the past twelve years. According to the article, Northrop Grumman significantly lowered its price for this launch, charging the Space Force $28.1 million, about half of what it charged NASA for that 2019 flight. Whether this is an effort to make the rocket more competitive, or is simply Northrop Grumman selling off its inventory, will remain to be seen.

The leaders in the 2021 launch race:

18 SpaceX
16 China
8 Russia
2 Rocket Lab
2 ULA
2 Northrop Grumman

The U.S. now leads China 25 to 16 in the national rankings.

China releases more images from Zhurong

12:34 pm

Zhurong looking north past its lander
Click for full image.

The new colonial movement: Three weeks after its Mars rover Zhurong rolled off its lander to begin its 90 day mission, China yesterday finally released the first high resolution images taken by the rover.

The images included a 360 degree panorama, taken while the rover was still sitting on the lander, an image of both the rover and lander taken by a mini-camera that was dropped from the bottom of the rover, a picture of some interesting nearby boulders to the east, and a picture looking past the lander looking north.

This last picture is above, reduced and annotated by me. The small flat but distinct hill to the north I think is the nearest pitted cone that could be either a mud or lava volcano. That cone is about 3.75 miles away, and though a very enticing target is probably too far away for Zhurong to reach, unless it survives for years past its planned three-month mission, as did the American rovers Spirit and Opportunity.

The closer small ridges and hills just to its right could be the east and west rims of the nearest large crater, about 650 feet wide with a distorted shape, that is visible in the high resolution orbital images taken by both Tianwen-1 and Mars Reconnaissance Orbiter (MRO). This crater is about 1,600 feet away.

Based on these images it appears that once Zhurong rolled off the lander to the east, it immediately turned to the right to move several feet south, where it turned right again to move several feet to the west until it was just to the west of the lander, where it took the picture above. During that last move it dropped the small camera behind it so that it could take the picture showing both the rover and the lander.

These maneuvers and the rover’s position south of the lander and facing west suggest they are going to head to the west, where there are some nearby smaller craters and other interesting features. Whether they eventually go north, with that pitted cone a long term goal should the rover last longer than its planned mission through the end of August, remains entirely unknown.

Blue Origin sells first tourist seat on New Shepard for $28 million

11:30 am

Capitalism in space: In a live auction today, Blue Origin successfully sold the first tourist seat on the first manned commercial suborbital flight of its New Shepard spacecraft for $28 million. With the additional fee of 6%, the total price was about $29.6 million.

I have embedded the replay of the auction below the fold, cued up to the auction start.

The bidding was amazingly fierce and aggressive, starting at $4.8 million. The final price is quite spectacular, actually $9+ million higher than what Dennis Tito paid to fly to ISS for several days back in the 1990s.

One wonders what SpaceX and Axiom have been charging for their orbital flights. I doubt it is this much. As I watched I wondered if the bidders were considering the time they would spend with Jeff Bezos as part of the value. These are wealthy people, and getting a chance to spend a lot of time with one of the richest men in the world might be far more valuable to them than the flight itself.

Regardless, we will know soon who won the auction, and will fly into space for a few minues or so on July 20th.

Zhurong finally located on Mars

11:58 am

Zhurong as seen by MRO
Click for full image.

Though the Chinese had earlier this week released one image taken by their Mars orbiter, Tianwen-1, showing their rover Zhurong on the surface of Mars, they did not provide any specific location information.

This lack has now been filled by a new high resolution image of Zhurong taken by Mars Reconnaissance Orbiter (MRO) on June 6, 2021. This image, cropped to match the Tianwen-1 image and annotated by me to post here, shows the parachute, entry capsule, heat shield, lander, and rover. I have added white dots to distinguish the rover from the lander, which indicate that since the Tianwen-1 orbital image the rover had moved south about 70 feet, suggesting it has been able to travel on the surface.

What this MRO image provides that the Chinese refused to reveal is the latitude and longitude of that landing site, which in turn tells us that the lander put down about 14 miles to the northwest of its targeted landing spot. The mosaic of MRO context camera images below show this landing spot in context with the surrounding terrain.

Update on Perseverance’s future travel plans

10:47 am

Perseverance's future travels
Click for full image.

The science team for the rover Perseverance yesterday released a revised map of where they intend over the next few months to send the rover on the floor of Jezero Crater.

The map to the right, cropped and reduced to post here, shows that route.

The first science campaign (depicted with yellow hash marks) begins with the rover performing an arching drive southward from its landing site to Séítah-North (Séítah-N). At that point the rover will travel west a short distance to an overlook where it can view much of the Séítah unit. The “Séítah-N Overlook” could also become an area of scientific interest – with Perseverance performing a “toe dip” into the unit to collect remote-sensing measurements of geologic targets.

Once its time at the Séítah-N Overlook is complete, Perseverance will head east, then south toward a spot where the science team can study the Crater Floor Fractured Rough in greater detail. The first core sample collected by the mission will also take place at this location. After Cratered Floor Fractured Rough, the Perseverance rover team will evaluate whether additional exploration (depicted with light-yellow hash marks) farther south – and then west – is warranted.

Whether Perseverance travels beyond the Cratered Floor Fractured Rough during this first science campaign, the rover will eventually retrace its steps. As Perseverance passes the Octavia B. Butler landing site, the first science campaign will conclude. At that point, several months of travel lay ahead as Perseverance makes its way to “Three Forks,” where the second science campaign will begin.

At that point the rover will begin studying the base of the delta of material that in the far past poured through a gap in the western rim of Jezero Crater.

“The Endless SLS Test Firings Act”

9:46 am

The Senate passes a law! In the NASA authorization that was just approved by the Senate and awaits House action was an amendment — inserted by Senator Roger Wicker (R-Mississippi) — that will essentially require NASA to build an SLS core stage designed for only one purpose, endless testing at the Stennis Space Center in Mississippi.

The Stennis-specific provision says NASA should “initiate development of a main propulsion test article for the integrated core stage propulsion elements of the Space Launch System, consistent with cost and schedule constraints, particularly for long-lead propulsion hardware needed for flight.”

So what exactly is a “main propulsion test article,” and why does NASA need one? According to a Senate staffer, who spoke to Ars on background, this would essentially be an SLS core stage built not to fly but to undergo numerous tests at Stennis.

My headline above is essentially stolen from the Eric Berger article at the link. Because this ground test core is not funded, at best it would likely not be ready for testing prior to ’27 or ’28, at the earliest. By then who knows if SLS will even exist any longer, replaced by low-cost and far more useful commercial rockets. Thus, if this Wicker amendment survives, Stennis might be testing a core stage endlessly for a rocket that no longer exists.

And even if SLS is flying, what point is there to test a core stage that never flies? None, except if you wish to create fake jobs in Mississippi for your constituents, as Wicker obviously is trying to do.

Fortunately the bill is merely an authorization, and has not yet passed the House. Much could change before passage, and even after passage money will need to be appropriated to create this fake testing project.

Unfortunately, we are discussing our modern Congress, which has no brains, can’t count, and thinks money grows on trees. I would not bet against this fake testing program becoming law.

Europe to fly mission to Venus to study its volcanoes

9:32 am

The European Space Agency yesterday announced that it will fly an orbiter to Venus in 2031, dubbed EnVision, to study the estimated million volcanoes on the surface of that hellish planet.

EnVision will use an infrared spectrometer to seek out hot spots on the surface that could indicate active volcanoes. It will use radar to map the surface, looking for signs of lava flows. Ultraviolet and high-resolution infrared spectrometers will then look for water vapor and sulfur dioxide emissions, to see whether smoldering volcanoes are driving cloud chemistry today.

This data will help determine exactly geologically active Venus’s volcanoes are. Several studies in the past decade using archival data (see here, here, and here) have suggested as many as 37 of those volcanoes are active, but this data remains uncertain.
