American astronaut seat liner shifted to Dragon temporarily

2:58 pm

Though NASA has not issued an update, the Soyuz seat liner used by American astronaut Frank Rubio was supposed to be shifted from the leaking Soyuz capsule to Endurance today, just in case that Soyuz needs to be used as a lifeboat. From the January 13th ISS update:

On Thursday, Jan. 12, the International Space Station mission management team polled “go” to move NASA astronaut Frank Rubio’s Soyuz seat liner from the Soyuz MS-22 spacecraft to Dragon Endurance to provide lifeboat capabilities in the event Rubio would need to return to Earth because of an emergency evacuation from the space station. The seat liner move is scheduled to begin Tuesday, Jan. 17, with installation and configuration continuing through most of the day Wednesday, Jan. 18. The change allows for increased crew protection by reducing the heat load inside the MS-22 spacecraft for cosmonauts Prokopyev and Petelin in the event of an emergency return to Earth.

Once the replacement Soyuz MS-23 arrives at the space station on Feb. 22, Rubio’s seat liner will be transferred to the new Soyuz and the seat liners for Prokopyev and Petelin will be moved from MS-22 to MS-23 ahead of their return in the Soyuz.

I expect that once this work is completed tomorrow NASA will issue an update.

The sea of dunes surrounding the Martian north pole

The sea of dunes surrounding the Martian north pole
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on December 5, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a collection of wormlike dunes located in the giant sea of dunes that surrounds the Martian north pole ice cap.

North is to the top. The season when this picture was taken was northern winter. The Sun is barely above the horizon, only 8 degrees high, and shining from the southeast. Because it is winter it is also dust season, making the atmosphere hazy and thus making the light soft. No distinct shadows, except that the sides of the dunes facing away from the Sun are darkly shadowed.

The consistent orientation of the dunes suggests that the prevailing winds blow from the northeast to create the steep-sided alcoves. The wind however might not be the only factor to form these dunes.

Hakuto-R completes five of ten milestones on test flight

7:56 am

Ispace’s private commercial lunar lander, Hakuto-R, has now completed five of the ten milestones the company had established before launch as its goals on this first test flight to the Moon.

The first five milestones completed are:

  • Completion of launch preparations
  • Completion of launch and deployment
  • Establishment of a Steady Operation Status
  • Completion of the first orbital control maneuver
  • Completion of stable deep-space flight operations for one month

The next five milestones involve entering final lunar orbit and landing successfully, the most difficult milestones of all.

SpaceX to build five Starship/Superheavy prototypes in 2023

7:51 am

According to Elon Musk, SpaceX intends to build five Starship/Superheavy prototypes in 2023 for flight testing.

Assuming they can get launch permits, these five rockets should provide the company ample launch testing capability for at least the next two years, especially if it succeeds in landing these units and can consider reusing them in test flights.

At this moment, the launch permits from the federal government appears the main obstacle to getting this heavy lift reusable rocket tested and operational.

Pushback: Southwest flight attendant demands Southwest be sanctioned for violating the terms of her court victory

12:33 pm

Southwest: Enemy to free speech

Bring a gun to a knife fight: Charlene Carter, a flight attendant who had worked at Southwest Airlines for 20 years, was fired in 2017 because she had publicly opposed for religious reasons the use of her union dues to fund pro-abortion protests, and was then reinstated after winning her lawsuit against the airline, is now demanding the court sanction Southwest for violating the terms of her court victory.

In her victory, Southwest was required to reinstate Carter with full benefits, and also issue a statement to its employees that it “may not” engage in religious discrimination. Instead, the airline sent out two notices. The first simply stated “that the Court ordered the company to notify them that it ‘does not’ discriminate on the basis of religion.” The second notice however was worse, as it once again slandered Carter for her religious beliefs.

A Martian river canyon?

A Martian river canyon?
Click for full image.

Today’s cool image highlights the biggest mystery of Mars that has baffled scientists since the first good pictures of its surface were taken in the early 1970s by the Mariner 9 orbiter. The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a very small segment of the 400-mile-long meandering canyon on Mars called Nigal Vallis. From the Wikipedia page:

The western half of Nirgal Vallis is a branched system, but the eastern half is a tightly sinuous, deeply entrenched valley. Nirgal Vallis ends at Uzboi Vallis. Tributaries are very short and end in steep-walled valley heads, often called “amphitheater-headed valleys.”

We can see one of those short tributaries on the image’s left edge. The overview maps below provide a wider view of this entire canyon.

SpaceX’s Falcon Heavy successfully launches Space Force satellites

4:06 pm

SpaceX’s Falcon Heavy rocket today successfully launched a Space Force communications satellite plus a secondary military payload.

The two side boosters completed their second flight, landing at Cape Canaveral. The core stage was not recovered, as planned. Actual deployment of the satellites will not occur for another six hours.

At this moment China leads SpaceX 5 to 3 in the 2023 launch race. No one else has as yet launched successfully.

Russia delays three planned lunar probes because of sanctions

10:56 am

The research division that is building Russia’s Luna 26, Luna 27, and Luna 28 probes to the Moon announced today that these missions will likely be delayed up to two years because many needed components are no longer obtainable due to the international sanctions imposed on Russia because of its invasion of the Ukraine.

“Previously, we designed equipment using foreign components that we could buy from our foreign colleagues. Now that the sanctions have been imposed, we will [be switching to] Russian-made components,” Mitrofanov explained. According to him, researchers have to change design solutions amid the Western restrictions.

Some of these components cannot be so easily replaced by Russian versions. Assuming the Ukraine war does not end soon, expect even longer delays for these unmanned lunar missions.

Stratolaunch’s Roc airplane completes 2nd captive-carry test flight

3:48 pm

Stratolaunch’s giant Roc airplane, the largest in existence, successfully completed its second captive-carry test flight, carrying a Talon-A (TA-0) hypersonic test vehicle under its central fuselage during take-off and landing.

The flight set a new duration record lasting a total of six hours and reached a maximum altitude of 22,500 ft., representing another important step forward in the company’s near-term goal of completing separation testing with TA-0. Primary test objectives included flight outside of the local Mojave area for the first time and evaluation of the separation environment. Roc and TA-0’s onboard data systems provide critical information on the aerodynamic loads and moments prior to release of TA-0, helping to ensure safe separation of the vehicle from Roc. The flight team also practiced chase formation and communication sequencing for the upcoming separation test.

The company has a contract with the Air Force to use the operational Talon-1 spacecraft, released from Roc, to do hypersonic test flights, hopefully in the first half of 2023.

Sweden cuts ribbon on Esrange spaceport

3:42 pm

Sweden yesterday officially inaugurated a new commercial launch site at the Esrange spaceport that the ESA had used previously for suborbital tests.

The site is an extension of the Esrange Space Centre in Sweden’s Arctic, around 40 kilometres (25 miles) from the town of Kiruna. Around 15 million euros ($16.3 million) have been invested in the site, which is expected to serve as a complement to Europe’s space hub at Kourou in French Guiana. It will also provide launch capabilities at a time when cooperation with Russia and the Baikonur launch site in Kazakhstan has been curtailed by the war in Ukraine.

Esrange’s state-owned operator, the Swedish Space Corporation (SSC), aims to launch its first satellite from the site “in the first quarter of 2024”, a spokesman told AFP on Friday.

At this moment, there are three commercial rocket spaceports racing to complete the first orbital launch from Europe. Esrange in Sweden and the two UK spaceports, Spaceport Sutherland in Scotland and SaxaVord in the Shetland Islands. Cornwall in the UK is an airport, so it can only launch rockets that use an airplane, which essentially limits its launch customers to Virgin Orbit.

Touring the largest organ in the world

6:01 pm

An evening pause: Specifically, this tour takes us from the bottom to the top of the largest pipe, and then shows us what comes out when you play it.

Hat tip Judd Clark, who provides this additional information:

Constructed between May 1929 and December 1932, the Main Auditorium Organ is the “Poseidon”, built by the Midmer-Losh Organ Company, and is the world’s largest pipe organ. Also included in this organ are pipes operating on 100 inches of pressure, the Grand Ophicleide being the loudest and also most famous. The instrument has an estimated 33,113 pipes and requires approximately 600 horsepower (450 kW) of blowers to operate.

Chinese company based in Hong Kong signs deal to build spaceport in Djibouti, Africa

2:57 pm

Djibouti's location in Africa
Djibouti’s location is indicated in black.

The government of Djibouti, one of the smallest nations in Africa and located at the southern end of the Red Sea, has signed an agreement with a pseudo Chinese company, the Hong Kong Aerospace Technology Group, to build a major spaceport there.

According to the translated press release, the five year project will cost one billion dollars, include a lease for 30 years, and involve the construction of a port, highway, and electrical power distribution system.

As much as Hong Kong for more than two centuries has been a haven for private enterprise, it is now under the control of the communist Chinese, and they would not allow anyone from Hong Kong to make such a deal unless they were in full control.

Based on the map, there is almost no launch path out of Djibouti that will not cross another nation’s territory. Unless the Chinese plan to make all the first stages launched from this site reusable, they are going to dropping stages on a lot of people’s heads, without their permission. And they will be doing it to some places where war is often and continues to be the most frequently used negotiating tactic.

Hat tip to stringer Jay.

Pushback: Blacklisted Virginia Tech soccer player wins $100K settlement

2:07 pm

Kiersten Hening, blacklisted by Virginia Tech
Kiersten Hening

Bring a gun to a knife fight: Kiersten Hening, a former Virginia Tech student and soccer player, has won a $100k settlement from the university and her former coach, Charles Adair, for blacklisting her from the team because she refused to kneel in support of Black Lives Matter during the National Anthem before a game.

In December Adair had lost in his attempt to obtain qualified immunity, and thus he became personally liable for his improper and discriminatory actions against Hening that violated her first amendment rights. Rather than allow the case to go before a jury, it appears Adair and the university negotiated a settlement. And while the settlement terms have not been made public, and Adair’s comments to the press try to imply that he got off scot free, this comment by one of Hening’s lawyer gives us a hint:

Attorney Adam Mortara tweeted in reply to Adair’s statement: “If by clarity you mean you are paying my client six figures in a settlement then you’re right that’s pretty clear. Honestly, Coach, read the Court’s opinion. You are paying. Defendants don’t pay in cases that have no standing.”

Mortara went on to thank Adair and his “bosses at Tech for paying the equivalent of several years of tuition.”

Whether this is a victory for free speech remains very unclear, however. Even if Adair did pay up, he remains the soccer coach at Virginia Tech, and clearly has the support not only of the administration but the women’s soccer community there:

Searching for surface changes caused by the biggest recorded Martian quake

1:27 pm

Location of May quake
The white patches mark the locations on Mars of the largest quakes detected by InSight

On May 4, 2022, the seismometer on the InSight Mars lander detected a 4.7 magnitude earthquake on Mars, the largest ever detected.

The map to the right shows the approximate location of that quake by the white patch with the green dot. (You can read the paper describing this quake here [pdf].) This is also the same approximate location of a small five-mile-wide crater known to have many slope streaks on its interior walls.

Slope streaks are a uniquely Martian geological feature whose origin remains unknown. They resemble dark avalanche streaks flowing downhill, but make no changes in the topography, and lighten with time. They also occur randomly throughout the year. Two slightly different theories for their formation suggest that the streaks are triggered by the fall of dust particles, though neither is proven or even favored.

If either of these theories are true, then the 4.7 magnitude earthquake at this location should have caused the formation of more streaks. To find out, scientists have used the high resolution camera on Mars Reconnaissance Orbiter (MRO) to compare that crater both before and after the quake to see if any new streaks has appeared. Below is a side-by-side comparison of these images.

FCC votes to create its own space bureaucracy, despite lacking statutory authority

9:55 am

On January 9, 2023 the commissioners of the Federal Communications Commission FCC voted [pdf] to create its own space bureaucracy designed to regulate the lifespan of new satellites, despite lacking legal authority to do so.

As noted almost as an aside by this news article,

In order for the planned changes to go into effect, the FCC will first have to obtain congressional approval for the reorganization and place a notice in the Federal Register.

This vote pushed forward the plan announced in November that attempts to expand the regulatory power of the FCC beyond its legal authority. Expect Congress to push back somewhat, but right now most power in Washington is held by unelected bureaucracies like the FCC, not the elected legislators as defined by the Constitution. The FCC will continue to push hard, and mostly win in this power game. Congress right now is too divided and weak to fight back.

The result will be new regulations on satellite construction made by non-engineers and paper-pushers in the FCC, not engineers and managers in the companies actually building the satellites.

Construction of the Thirty Meter Telescope in Hawaii remains in limbo

9:33 am

Despite the successful power grab by protesters that stopped construction and took management of the telescopes on Mauna Kea in Hawaii away from the University of Hawaii and gave it to a newly created board made up of “observatory representatives, Native Hawaiian cultural practitioners, local business and education officials, and experts in land management,” construction of the Thirty Meter Telescope (TMT) in Hawaii remains in limbo.

But there is another actor in this drama: the National Science Foundation (NSF). TMT has accrued substantial financial backing from its university backers and the governments of China, Japan, India, and Canada, but it is still far from fully funded and has asked NSF to fill the gap. TMT’s request has come in partnership with the Giant Magellan Telescope (GMT), another U.S.-led effort to build a massive new telescope. GMT’s site is already being prepared in Chile but it is also in financial straits.

Together, the two projects are seeking $3 billion from NSF in exchange for the wider U.S. astronomical community gaining access to a large slice of both scopes’ observing time. That proposal was judged by U.S. astronomers as their top priority for ground-based astronomy in the community’s decadal survey published in November 2021. NSF is now assessing whether this is a good investment for U.S. taxpayers.

Considering that Congress now believes that money grows on trees, and there is no reason not to fund anything anyone wants no matter how much debt it produces, I expect that the NSF will eventually fund both telescopes. There is however the slim possibility that the NSF will look at the new and very complex managerial make-up now running things in Hawaii and decide it is impractical and guaranteed to produce problems. The goals of the different members of this board are so contradictory that any construction on Mauna Kea will likely have to be renegotiated over and over again, causing further delays.

Of course, endless funding and delays could be considered a feature, not a bug, by our present corrupt federal government. In that case the NSF will celebrate these delays.

Lunar Flashlight cubesat in trouble

9:18 am

The mission of NASA’s test cubesat Lunar Flashlight is now threatened because of a problem with its experimental thrusters that use what the agency labels a new “green” propellant.

The spacecraft, called Lunar Flashlight, launched last month on a mission to seek out water ice on the moon. The probe was also expected to test a new “green” propellant during its four-month voyage to the moon, but its thrusters have a problem, NASA said on Thursday (Jan. 12). “While the smallsat is largely healthy and communicating with NASA’s Deep Space Network, the mission operations team has discovered that three of its four thrusters are underperforming,” NASA wrote in an update. “Based on ground testing, the team thinks that the underperformance might be caused by obstructions in the fuel lines that may be limiting the propellant flow to the thrusters.”

Engineers are now devising a plan to fire the thrusters longer and more frequently to make up for the lower thrust. If successful, the cubesat will enter its planned lunar orbit in about four months, where it will use infrared lasers to search for ice in the permanently shadowed craters at the lunar poles while testing a variety of other new technologies.

China completes two launches today

9:07 am

China today continued its normal fast pace of winter launches, launching twice from two different spaceports.

First, a Long March 2C rocket launched a communications satellite from the Xichang Satellite Launch Center in southwest Sichuan Province. Then, a Long March 2D rocket launched three classified technology test satellites from the Jiuquan Satellite Launch Center in northwest China.

As I noted in yesterday’s quick space links, the drop zones for both were in China. No word as yet on whether anything fell near habitable area.

At present the 2023 launch race consists entirely of China with four launches, and SpaceX with two.

What some conservatives are going to have to face to bring liberty back to America
What some conservatives are going to have to face
to bring liberty back to America

A wise man once said that to beat your enemy you need to know him better than he knows himself. It is to this purpose I write this essay.

Even now, with blacklisting, censorship, and intolerance against dissent the normal standard held by our leftist elitist intellectual class, conservatives still assume naturally that anyone they meet anywhere, whether on the street, at their job, or among their family, are old-fashioned freedom-loving Americans who — whether they are Republicans or Democrats — will stand together for liberty wherever tyrants strike.

This assumption is 100% wrong, and it is why conservatives have been so steadily losing ground in the battle for freedom for decades. Blacklisting is now acceptable to a large percentage of Americans on the left. Censorship and violence against their opponents is okay, and is actually considered the right thing to do for many ordinary Democrats.

Just yesterday the Democrats themselves in Congress proved this point. When faced with a bill that simply condemned the more than hundred violent attacks against “pro-life facilities, groups, and churches” since the May 2, 2022 leak of the Supreme Court decision striking down Roe v Wade, 208 out of 211 Democrats voted against it.

The bill did not support the banning of abortion. All it demanded that Congress:

Racing above the clouds of Jupiter
Click for full image.

Cool image time! The photo above, reduced in size to post here, was created from a raw Juno image by citizen scientist Kevin Gill. From his caption:

A low perspective over Jupiter’s North Polar Storms. Used imagery from the Juno spacecraft’s recent Perijove 47 to render a simulated view as if the viewer were only a few thousand kilometers above the clouds. Applied simulated altimetry, shadowing, and upper atmospheric transparency depth in Blender and Photoshop to render this.

To get some perspective on how large Jupiter is, the planet’s curve is about comparable to the same curve seen by astronauts of the Earth at a height of about 300 to 400 kilometers. In this image however we are about ten times higher.

First exoplanet confirmed by Webb

10:23 am

Astronomers have used for the first time the Webb Space Telescope to confirm the existence of an exoplanet, previous noted in data from the orbiting TESS telescope.

Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter. The research team is led by Kevin Stevenson and Jacob Lustig-Yaeger, both of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.

The team chose to observe this target with Webb after carefully reviewing targets of interest from NASA’s Transiting Exoplanet Survey Satellite (TESS), which hinted at the planet’s existence. Webb’s Near-Infrared Spectrograph (NIRSpec) captured the planet easily and clearly with only two transit observations.

The data is still preliminary, so more analysis is necessary to provide some information about the planet’s atmosphere.
