- Soyuz capsule placed inside its payload fairing for a likely February 21th launch
That date, reported by Roscosmos two days ago, is three days earlier than the date listed at the link. Unless something has changed and not been reported, I would favor the earlier reported date.
- Images of the new Angara rocket assembly stand at Vostochny
Looks very clean and sleek, but also has taken decades to build.
- Damaged Progress to undock from ISS shortly
Live stream is here, scheduled to go live around 6:15 pm Pacific. Following undocking the freighter will be maneuvered so that the leak in its coolant system on its service module can be photographed.
- U.S. military is loosening its rules for bidding on its launches
The language in the screen capture at the link is typical bureaucratic blather, but the bottom line is that the military is no longer limiting bidding on launch contracts to just SpaceX and ULA, a foolish program I have begging the military to abandon for years. At this point they will let others bid on missions that are less risk tolerant. Expect with time this policy to loosen even more, as more competition can only save the military money, while providing it more redundancy and capability.
- China’s Xuntian Space Telescope, a Hubble-class optical space telescope, is still targeting a ’24 launch
The telescope will orbit close to Tiangong-3, and according to images at the link, will dock with the station for maintenance.
- NASA’s corrupt safety panel worries about NASA’s “safety culture” in its Artemis program
Though in this case the panel is likely right, I don’t take anything it says seriously. It has been so wrong so many times in the past, clearly biased against private space while favoring NASA, its analysis is simply worthless. I only include the link to its report now for completeness.
- FAA proposes fining SpaceX $175K for not providing “launch collision analysis trajectory data” prior to a August 19, 2022 Starlink launch
SpaceX has 30 days to respond. Considering the increased hostility by the bureaucracy to SpaceX since Biden took office, I think it is understandable to think this is simply another bureaucratic attack for political reasons.
- One instrument on the Parker Solar Probe is temporarily down
It appears the problem simply requires a software upload of that instrument, which cannot be done for another few weeks because the spacecraft is in a blackout period due to orbital mechanics.
- Boeing and NASA still aiming for mid-April launch of first manned Starliner mission to ISS
That timeline remains in flux, and will be finalized in early March when they decide on when to begin fueling the service module. Once that happens, they need to launch with 60 days. Expect an actual launch date to announced around then.

SpaceX launches 51 Starlink satellites from Vandenberg
At 11:12 (Pacific) SpaceX today successfully launched another 51 Starlink satellites from Vandenberg Space Force Base in California, using its Falcon 9 rocket with a first stage making its ninth flight.
The first stage successfully landed on its drone ship in the Pacific. The fairing halves completed their fifth and sixth flights.
The 2023 launch race:
11 SpaceX
5 China
2 Russia
1 Rocket Lab
1 Japan
1 India
American private enterprise now leads China 12 to 5 in the national rankings, and the entire world combined 12 to 9. By itself SpaceX leads the world combined 11 to 9, and that lead will grow later today should the next Falcon 9 launch at 10:59 pm (Eastern) tonight from Cape Canaveral succeed.

Today’s blacklisted American: Professor sues University of Texas for threatening his job because he criticized it publicly
University of Texas at Austin to Professor Richard Lowery:
“Nice job you got here. Shame if something happened to it.”
They’re coming for you next: Professor Richard Lowery is now suing the University of Texas at Austin (UT-Austin) for its attempts to silence him, including threatening his job, cutting his pay, and monitoring his speech, actions instigated against Lowery because he was publicly critical of the university’s racist “diversity, equity, and inclusion” policies as well as the university’s efforts, led by its president Jay Hartzell, to insert political propaganda into its courses.
Lowery is being represented by the Institute for Free Speech, which filed his lawsuit [pdf] on February 8, 2023.
The campaign [against Lowery and his allies at the university] started by pressuring Carlos Carvalho, another professor of business at the UT McCombs School who is also the Executive Director of the Salem Center for Public Policy, an academic institute that is part of the McCombs School. Lowery is an Associate Director and a Senior Scholar at the Salem Center and reports to Carvalho.

A galaxy’s structure of gas and dust, as seen in the infrared by Webb
NGC 1433 as seen in the infrared. Click for original image.
Scientists have now released 21 papers on the gas and dust structures in nearby galaxies, based on infrared images from the Webb Space Telescope, used in collaboration with other telescopes looking in other wavelengths.
The largest survey of nearby galaxies in Webb’s first year of science operations is being carried out by the Physics at High Angular resolution in Nearby Galaxies (PHANGS) collaboration, involving more than 100 researchers from around the globe. The Webb observations are led by Janice Lee, Gemini Observatory chief scientist at the National Science Foundation’s NOIRLab and affiliate astronomer at the University of Arizona in Tucson.
The team is studying a diverse sample of 19 spiral galaxies, and in Webb’s first few months of science operations, observations of five of those targets – M74, NGC 7496, IC 5332, NGC 1365, and NGC 1433 – have taken place.
The image to the right is Webb’s infrared image of NGC 1433, estimated to be 46 million light years away. The bright areas extending outward in the spiral arms are believed to be star-forming regions. From the caption:
At the center of the galaxy, a tight, bright core featuring a unique double ring structure shines in exquisite detail with Webb’s extreme resolution. In this case, that ‘double ring’ is actually tightly wrapped spiral arms that wind into an oval shape along the galaxy’s bar.
NGC 1433 is a Seyfert galaxy, which are typically relatively close to Earth and has a supermassive black hole at the center eating material at a high rate. The brightness and lack of dust in the MIRI image of NGC 1433 could hint at a recent collision with another galaxy.
When comparing Webb’s infrared view with Hubble’s optical view, taken in 2014 and found here, the differences are definitely striking. Webb sees the gas and dust that is dark in Hubble’s images, while Hubble sees things at much higher resolution and thus sees more fine detail.

China releases data sets from Chang’e-4 lander
China today released another set of data from the instruments on the Chang’e-4 lander, which landed on the far side of the Moon on January 3, 2019, bringing with it China’s Yutu-2 rover.
The datasets include 3,991.1 MB of 803 data files obtained by the four scientific payloads on the Chang’e-4 lander and rover between December 26, 2021 and January 10, 2022.
The data was posted on the official website of the Lunar and Planetary Data Release System, though none of the press reports from multiple China’s state-run press sources include it. All are simply the same three paragraph story, word for word. That site however is here, though it is entirely in Chinese and the English pages fail to load.

For only 7th time, searchers find meteorite immediately after fall
For only 7th time, searchers on February 15th found a fragment of a meteorite that had only fallen to Earth three days before, and was furthermore only discovered mere hours before it entered the Earth’s atmosphere.
From the tweet of the discoverers:
FRIPON/Vigie-Ciel finds a fragment of asteroid 2023CX1 in Seine Maritime!!! The discovery was made by Loïs Leblanc, an 18-year-old student, part of the field research team.
Vigie-Ciel (“Sky Watchers”) and FRIPON are a volunteer project that searches for meteorites. The asteroid itself was discovered by Hungarian astronomer Krisztián Sárneczky while doing routine survey scan for near Earth asteroids.
The find was the second time Sárneczky has spotted an asteroid just hours before it broke apart in Earth’s atmosphere as a fireball, following an incredible find in March 2022.
By finding meteorites this quickly after arrival scientists get a more pristine sample, since the asteroid has not been exposed to the Earth’s environment for any extended length of time.

The February 2023 Behind the Black fund-raising campaign-THANK YOU
My annual February fund-raising campaign is now over. I decided to shorten it by two weeks because I was tired of begging my readers for money. As expected, this will likely make this a much smaller campaign then previous years. So be it.
Nonetheless, I sincerely and with deep gratitude thank all those who donated. Without your support I could not keep doing this, not so much because of the need for income to pay the bills, but because it tells me that there are people out there who want me to do this work.
For those who did not contribute during the campaign, the tip jar is still somewhere on this webpage. Please consider adding your vote of support to Behind the Black.
First launch of Japan’s H3 rocket aborts at T-0
In its first attempt to launch its new H3 rocket today the rocket’s main liquid-fueled engines ignited, but then the two strap-on solid rockets failed to ignite at T-0, causing that main engine to shut down to protect the rocket and payload.
I have embedded the live stream below, cued to about T-39. At the end of the broadcast the rocket appeared in good condition, though it was still unclear what the caused the problem.
At the moment there is no word when JAXA, Japan’s space agency, will attempt another launch. The H3 is years behind schedule, and was developed in the hope it would be more efficient and cost less to launch than the H2A rocket Japan presently uses.

Ingenuity completes 43rd flight on Mars, the longest in almost a year
Click for interactive map.
The Mars helicopter Ingenuity today successfully completed its 43rd flight on Mars, traveling 1,280 feet for 2 minutes and 26 seconds.
The green dot on the map to the right marks Ingenuity’s position before the flight, with the green lines marking the approximate direction and distance flown. The Perseverance/Ingenuity team has not yet updated its interactive map, so the precise landing spot is not yet available.
This flight was the helicopter’s longest since April 2021, just before the onset of the long six-month-long Martian winter. At that time Ingenuity completed its 28th flight, traveling 1,371 feet. Since then engineers struggled to keep Ingenuity alive during the dark winter, a task made more difficult due to an unexpected higher winter dust storm season.
Winter however is over, the helicopter is now fully charging with no problem, and has new flight software that allows it to go higher and over rougher terrain. In fact, like the last flight, Ingenuity flew farther and longer than planned, as it had been programmed to go 1,235 feet for 2 minutes and 17 seconds. That extra 45 feet and 9 seconds were likely used by the helicopter to locate a safe landing spot.
For perspective, Ingenuity’s total mission was originally planned to last only 30 days, and complete about a half dozen test flights merely to prove the concept of flight on Mars was possible. It has now lasted two years, completed 43 flights, and traveled almost five and a half miles. An amazing engineering achievement by JPL’s engineering team.

Today’s blacklisted American: Rhode Island still pushing racist hiring practices despite civil rights complaint

original flyer.
They’re coming for you next: Despite a civil rights complaint filed back in November 2022 against Rhode Island’s Providence Public School District for offering only “educators of color” a $25,000 loan forgiveness, that school district has continued to offer this discriminatory and racist benefit to only certain races, including a hiring event that occurred just yesterday.
The flyer for yesterday’s event is to the right. Note the circled text.
You can read the complaint here [pdf], filed by the Legal Insurrection Foundation. According to this news report a week ago, the federal Office of Civil Rights “…was making a formal referral of the Complaint to the Equal Employment Opportunity Commission (EEOC) for investigation. EEOC already has assigned an investigator to the case.”
Yet, despite its clear bigoted illegality and the existence of a legal action against it, the Providence Public School District doesn’t care. » Read more

The endless volcanic ash of Mars’ Medusae Fossae Formation
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on January 6, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a small but typical area of the Medusae Fossae Formation, what is thought to be the largest volcanic ash deposit on Mars.
The picture itself was a “terrain sample,” taken by the MRO science team not as part of any specific research but to fill a gap in the camera’s schedule so as to maintain its temperature. The terrain itself looks like a field of sand that someone had run a fine comb across. In this case, the comb was the winds of Mars, prevailing from the southeast to the northwest. The crescent-like divots in the picture’s lower right are probably caused by some hard underground feature that the winds cannot blow away. Instead, it blows around, like water in rapids flowing around a rock, and takes the ash with it as it does so.

NASA outlines its expected needs as a space station customer
NASA has now published an updated detailed specification of what it will want to do on the four private space stations being built to replace ISS.
NASA published two white papers Feb. 13 as part of a request for information (RFI) for its Commercial Low Earth Orbit Destinations effort to support development of commercial stations. The documents provide new details about how NASA expects to work with companies operating those stations and the agency’s needs to conduct research there.
One white paper lists NASA’s anticipated resource needs for those stations, including crew time, power and volume, broken out for each of the major agency programs anticipated to use commercial stations. Companies had been seeking more details about NASA requirements to assist in the planning of their stations.
,,,The second white paper outlines the concept of operations NASA envisions for its use of commercial space stations. The 40-page document described in detail what it expects from such stations in terms of capabilities, resources and operations, as well as what oversight the agency anticipates having.
At the moment NASA has contracts with four different space station companies or partnerships, Axiom, Blue Origin, Nanoracks and Northrop Grumman, each of which is building its own station. Because NASA will initially be the biggest customer for these stations its requirements will help shape those stations significantly, which is why this information is of critical importance for the private companies.
At the same time, NASA is not dictating specific designs. The agency remains the customer, buying time on private facilities that will be owned privately and be free to sell their product to others. Thus, the designs of these stations might not match exactly what NASA desires, since even now there are other customers interested in buying space station time and space.

Roscosmos will launch unmanned Soyuz to ISS on February 21
Roscosmos today announced that it will launch the unmanned Soyuz to ISS on February 21st, only a two-day delay after doing a quick inspection of its outer surface for possible damage following the coolant leak of a Progress freighter on February 11th.
BtB’s stringer Jay provided me this translation of the announcement at the link:
The Soyuz MS-23 spacecraft has been checked and is beginning to be prepared for launch. The preparations suspended the day before at Baikonur will resume tomorrow or the day after tomorrow.
The launch is scheduled for the 20th of February.
The ship was inspected. No maliciously drilled holes were found. We decided not to wait any longer. In any case, a refueled ship must either be launched or sent to a museum.
Update: removal of the launch vehicle to the launch pad on February 18, launch on February 21″ [emphasis mine]
The highlighted words are truly intriguing. It appears Roscosmos is desperately trying to convince the world that the repeated recent leaks to Soyuz and Progress spacecraft are not related to sabotage on the ground. At the same, Roscosmos has never told us the results of its investigation into the 2018 hole in a Soyuz capsule that someone drilled and then patched before launch. It seems incredibly unlikely that the two recent leaks in the exterior coolant systems of two different spacecrafts were both caused by impact from a micrometeorite or tiny piece of space junk. Two such impacts could of course occur this frequently, but for both to happen to such similar locations on only Russian spacecraft seems beyond improbable.
Either way, the decision makes some sense. The available lifeboats on ISS right now are really insufficient. Better to get this launched. More important, they had already begun fueling it, and once that is done the clock was running. They have to launch by a certain time.
Meanwhile it would be wise for NASA to begin arranging new emergency lifeboat arrangements with SpaceX as well as Boeing (once it finally gets Starliner operational). Depending on the Russians for even part of this responsibility seems ill advised. If preplanned properly, SpaceX could certainly launch one of its Dragon manned capsules quickly in an emergency.

An excellent summary. If you want to understand why I call all of China’s so-called private companies “pseudo,” watch this video. The earlier constellations planned by two pseudo companies vanished when the government decided something else should be launched instead. Neither company was private, and both were always entirely owned by the government.
- Flapless Starship prototype #26 rolled out to suborbital Pad A at Boca Chica for tests
Some have labeled this prototype the “bullet” because it also lacks tiles. SpaceX is clearly designing this for orbital tests without any intention of bringing it back to Earth safely. For all we know, the company might send it on an interplanetary flight for PR purposes.

“What the heck?!” swirls on Mars
Click for original image.
Time for another “What the heck?!” image on Mars. The picture to the right, cropped to post here, was taken on January 6, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is what the science team calls a “terrain sample,” which means it wasn’t taken as part of any specific scientific investigation and requested by a scientist. Instead, it was taken to fill a gap in MRO’s schedule. In order to maintain the camera’s proper temperature it is necessary for it to take regular pictures, and sometimes if there is a gap between requested images the science team picks something almost at random to fill the gap.
Sometimes the picture results in something relatively uninteresting. More often they try to pick something intriguing but not yet of interest to any particular researcher. With today’s cool image they certainly found something intriguing, so much so that I haven’t the faintest idea what is going on here.
Clearly, the tan swirls lie on the higher topology, and could be dust covered. The darker hollows in between could be darker because they are so, or because they are in shadow.

Stop participating in the delusions of the insane
“Lily” Mestemacher
In a perfect example of the modern madness of our time, when a bearded heavy-set man using the name “Lily” Mestemacher was arrested in Arkansas for making bomb threats against a location in Mississippi, the local news organization reporting the story in Mississippi used female pronouns to describe him because he claimed he was a woman. To quote that February 13, 2023 news report:
On February 10th, Mestemacher was transported to Oxford where she was booked on the aforementioned warrant. She was taken before a Lafayette County Justice Court judge for her initial bond hearing and issued a $50,000 bond. [emphasis mine]
His arrest mugshot is to the right. This is a man. Just because he is somewhat deranged and wants to make believe he is a woman does not require that local news organization, called The Local Voice, to participate in that derangement.

India’s government plans to sell tourist tickets on its future manned flights
The new colonial movement: It appears that once it completes its first manned mission in space, dubbed Gaganyaan, India’s government space agency ISRO intends to sell tourist tickets on future manned flights.
[Union Minister Jitendra] Singh, who also holds the portfolios of Personnel, Public Grievances and Pensions, informed the House that the objective of India’s maiden human spaceflight programme, ‘Gaganyaan’, is demonstration of human spaceflight capability to low earth orbit (LEO), which is a precursor to the future space tourism programme. “The ISRO has carried out a few feasibility studies for a sub-orbital space tourism mission,” the Union Minister revealed while announcing that after the accomplishment of the ‘Gaganyaan’ mission, activities towards space tourism would be firmed up.
Selling commercial tickets on its spacecraft would be completely in line with ISRO’s decades-long policy of trying to make money from its space capabilities. Whether this action however will help or hinder India’s independent space industry remains unclear. Like NASA a decade ago, there is a turf war in ISRO over whether to cede power to private enterprise, or hold it entirely in ISRO’s grip. If ISRO sells manned spaceflight tickets it will make it harder for private tourism companies to gain investment capital.

Perseverance’s depot of core samples, ready for pickup
Click for interactive map.
The Perseverance science team yesterday released the annotated mosaic above, cropped to post here, showing the scattered depot of core samples the rover deposited on the floor of Jezero Crater for later pickup some time next decade for return to Earth.
The overview map to the right shows the context. The blue dot marks Perseverance’s position when it took the picture, on January 31, 2023. The green dot marks Ingenuity’s location at that time. The yellow lines indicate the approximate area covered by the mosaic. The green outline indicates the area of the depot.
Eight of those tubes are filled with rock and regolith (broken rock and dust), while one is an atmospheric sample and one is a “witness” tube. The rover photographed the depot using the Mastcam-Z camera on the top of its mast, or “head,” on Jan. 31, 2023. The color has been adjusted to show the Martian surface approximately as it would look to the human eye.
The location of each tube was carefully mapped because it is possible wind will cover them with dust in the decade-plus before pickup. This mosaic will also act as a guide for the future Mars helicopters that will arrive to grab the core samples and bring them to an ascent spacecraft that will bring them back to Earth.

Imaging satellite builder Maxar signs contract with Umbra to use its radar satellites
Maxar, which operates a constellation of high resolution optical imaging satellites for commercial and military use, has now signed a contract with Umbra, which operates a constellation of high resolution radar satellites for commercial and military use.
The partnership will allow Maxar to directly task Umbra’s satellites and integrate synthetic aperture radar (SAR) data into its portfolio of Earth intelligence products and services, Tony Frazier, head of Maxar’s public sector Earth intelligence, told SpaceNews.
SAR is a specialized form of remote sensing that has been in growing demand since Russia’s invasion of Ukraine. SAR satellites can capture images at night, through cloud cover, smoke and rain — conditions that impair traditional optical satellites like those operated by Maxar.
The contract will give Maxar “assured access” to the soon-to-be launched six and seven satellites in Umbra’s constellation.
Essentially, this deal enhances Maxar’s value. Its main customer is the U.S. military, and it can now offer that military a more enhanced observation capability. Umbra meanwhile gets a major customer quickly, rather than having to pitch its product to multiple potential buyers. Its radar product is also enhanced, because it will now come automatically partnered with optical imagery.

Dislodged fuel filter identified as cause of Virgin Orbit launch failure
Virgin Orbit yesterday revealed that a dislodged fuel filter in LauncherOne’s upper stage caused the failure of the rocket to reach orbit during its January 9, 2023 launch from Cornwall, UK.
The data is indicating that from the beginning of the second stage first burn, a fuel filter within the fuel feedline had been dislodged from its normal position. Additional data shows that the fuel pump that is downstream of the filter operated at a degraded efficiency level, resulting in the Newton 4 engine being starved for fuel. Performing in this anomalous manner resulted in the engine operating at a significantly higher than rated engine temperature.
Components downstream and in the vicinity of the abnormally hot engine eventually malfunctioned, causing the second stage thrust to terminate prematurely.
The rocket thus did not have enough velocity to reach orbit, and fell in the ocean.
No word yet on when the company will next launch, though it has said that launch will be from Mojave, California.

- In fourth quarter of 2022 SpaceX placed almost as much mass into orbit as the entire rest of the world combined
For those who think upload mass the important metric, the graph at the link will answer many questions.
- Sierra Space touts its Vortex upper stage hydrogen-fueled engine, built in partnership with the Air Force
It is unclear on what rocket or spacecraft this engine will be used. Several years ago, early in development, the company said it would be for its Dream Chaser reusable mini-shuttle, but would use “green” fuels. I am not sure if hydrogen fits that bill.
- Engineers/scientists from China’s Academy of Sciences (CAS) go to ESA facility to help complete final tests on joint CAS-ESA solar mission
The mission, dubbed SMILE, will study the solar wind and its interaction with the Earth’s magnetosphere.
- Chinese atmospheric monitoring satellite shoots green lasers over Hawaii
The link includes a video of some of those lasers shots. The satellite, Daqi-1, was launched in April 2022. China claims it has no surveillance objectives.
- Europe joins the UK in investigating Viasat’s purchase of Inmarsat
The UK opened its own investigation in August 2022. In both cases, a decision against Viasat will likely hurt both companies, who are struggling to meet the new competition from the giant low orbit smallsat constellations like OneWeb and Starlink.
- Russia resumes prepping next Soyuz for launch
An inspection of the outside of the spacecraft’s cooling system found no damage or drilled holes. Expect the launch to occur before the end of February, relative close to its previous launch date of February 19th. As this is the lifeboat for three occupants of ISS, delaying its launch increases other risks.

SpaceX abandons plan to convert floating oil platforms into Starship/Superheavy landing spots
SpaceX has decided not to convert the two floating oil rigs it had purchased in 2020 into Starship/Superheavy landing platforms, and has sold both.
According to SpaceX CEO Gwynne Shotwell,
Shotwell said the company needed to first start launching Starship and better understand that vehicle before building offshore launch platforms. “We really need to fly this vehicle to understand it, to get to know this machine, and then we’ll figure out how we’re going to launch it.”
She said she expected offshore platforms to eventually play a role to support an extraordinarily high launch cadence. “We have designed Starship to be as much like aircraft operations as we possibly can get it,” she said in the conference presentation. “We want to talk about dozens of launches a day, if not hundreds of launches a day.”
This is a perfect example of this company’s intelligent ability to focus on the most important problems now, instead of getting distracted by future issues and challenges it knows exists but are not the priority at this time.

A glacial river on Mars
Click for full image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a wonderful example of a glacier-filled canyon on Mars, the ice apparently flowing both along and around mesas as it carves its way downhill.
I think the downhill grade here is to the north, but this could be wrong for the two side canyons on the main canyon’s north side.
Not only is the material in the canyon likely ice, covered with a protective layer of trapped dust and ash that makes the glacier surface look so smooth, the mesa tops are likely impregnated with ice as well. The mesas however have little dust, so the plateaus have a mottled stippled look likely caused by sublimation of that underground ice.
The location of these canyons explains the presence of ice.

Today’s blacklisted Americans: Religious pro-lifers prevented from viewing Bill of Rights because National Archives forbids free speech
An example of the evil pro-life clothing
banned by the National Archives
They’re coming for you next: Students and parents and others who had just attended the January 20, 2023 March for Life event in Washington were told by numerous National Archives security officials that day that they must remove or cover any pro-life shirts, jackets, hats, or buttons or they would be ejected from the museum.
From the lawsuit [pdf] filed by three of those pro-life individuals:
Plaintiff L.R., her mother, and her fellow classmates [about 35 people] were ushered through security and into the first group of visitors to enter the Rotunda where the Constitution and Bill of Rights are on exhibit.
…Approximately five minutes later, Plaintiff L.R. and her fellow classmates were suddenly approached by Defendant John Doe 1 who instructed Plaintiff L.R. and her classmates to remove all pro-life attire. John Doe 1 specifically instructed Plaintiff L.R. that she could not be wearing anything pro-life and that she must cover her shirt and not unzip it until she had left the National Archives. John Doe 1 also instructed Plaintiff L.R. and her other classmates to remove their pro-life buttons. John Doe 1 made other classmates standing near Plaintiff L.R. remove their pro-life hats. One such hat contained the inscription, “LIFE always WINS.” Another hat contained the inscription, “ProLife.” Plaintiff L.R. witnessed another guard participate in these instructions to her classmates and at no time did any of the other guards in the Rotunda intercede and provide contrary instruction.

Winter finally ends for Ingenuity
According to a detailed update today by Travis Brown, Chief Engineer of the Mars helicopter Ingenuity, the helicopter has now finally exited its difficult winter conditions that began in May 2022 and only ended at the end of January 2023.
One month to the day after the Dec. 24 flight attempt, Ingenuity did something it hadn’t done during the previous 260 sols – it slept “warmly” through the entire night. Data leading up to this event had suggested that such a survival was possible, but 8 long months of winter had tempered the team’s optimism. When Ingenuity’s team reviewed the downlinked data, they found that not only had it started living through the night, but had actually begun to bank power in its batteries. We’ve now seen end-of-sol states of charge in our batteries of more than 90% — an unbelievable number just days earlier. All the above means our sleepy friend has finally awoken from its long winter malaise, just in time to race up the Jezero Crater Delta and provide valuable advanced imaging for Perseverance.
Brown describes in detail their struggle for the past eight months to keep Ingenuity alive. That information is going to be crucial in designing future Mars helicopters, including the ones that will return to Jezero Crater sometime in the next decade to grab the core samples Perseverance has deposited for pick up and return to Earth.
