- SpaceX aiming to do two launches on the same day this weekend, from opposite coasts
The launch from Vandenberg is a set of Starlink satellites, while the Kennedy launch is a set of OneWeb satellites. The author at the link breaks down the number of launches last year at each pad, and notes SpaceX’s goals this year.
- Launch of China’s Long March 7A now set for January 8-9, 2023
This launch was originally set for December but was postponed. It is unclear whether it will be China’s first launch in 2023.
- Norfolk Naval Station by Taijing-3-01 remote sensing satellite, Sept 2022
China gives us a hint at its satellite reconnaissance capability, which according to Jay, in this case has less resolution than Google Earth.
Backlash against MIT’s blacklisting of teacher forces it to adopt Free Speech Resolution
Today’s blacklist story is really a follow-up on an earlier story from November 2021. At that time MIT had cowardly bowed to the demands of the intolerant left and cancelled a lecture on planetary science by a planetary scientist, Dorian Abbott, merely because Abbott had also posted videos on line advocating the radical idea of free speech.
This action by MIT however did not go unnoticed, and in fact produced an aggressive backlash from both alumni and faculty members. The alumni withdrew their financial support to the school, while a group of 73 faculty members signed a letter demanding the school support free speech.
The faculty suggest[ed] the adoption of the Chicago Statement, which states, in part: “[T]he University is committed to free and open inquiry in all matters, it guarantees all members of the University community the broadest possible latitude to speak, write, listen, challenge, and learn,” and that “it is not the proper role of the University to attempt to shield individuals from ideas and opinions they find unwelcome, disagreeable, or even deeply offensive.”
Out of this effort the MIT Free Speech Alliance was formed, aimed at forcing these changes at MIT.
Now, less than two months later, it appears that this effort has borne fruit. » Read more
Drainage out of a Martian crater
Click for full image.
Today’s cool image to the right, rotated, cropped, reduced, and sharpened to post here, not only gives us another example of a Martian geological feature that is unique to Mars and whose origins are not yet understood, it also shows what appears to have once been a lake-filled crater that over time drained out to the east through a gap.
This picture was taken on October 14, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The inexplicable geology is called brain terrain, and it fills the floor of the crater on the picture’s left side. The rim shows a gap, from which a meandering channel continues downhill to the east. The lake inside the crater might not have been liquid water, but ice. The channel might not have been formed by flowing water, but by a glacial flow downhill.
What makes this glacial evidence especially interesting is that it is located in a very different part of the Martian mid-latitudes.

- Astronaut Walt Cunningham has passed away
Cunningham only flew in space once, on Apollo 7, the first shakedown flight of the Apollo capsule in October 1968. The flight lasted ten days, had no technical problems at all, though all three astronauts caught colds. Its success paved the way for the Apollo 8 mission around the Moon two months later.
- LeoLabs files petition with FCC requesting it rethink the limitations it placed on SpaceX’s Starlink constellation [pdf]
It appears the FCC took an arbitrary number LeoLabs had used in a presentation merely for “ease of exposition and calculation in describing the methodology” and made it the basis for limiting the number of satellites SpaceX could launch. LeoLabs wants the FCC to fix this.
- The trailer for the Russian sci-fi movie, The Challenge, that was partly filmed on ISS last year, has now been released
It is very clear that they got a lot of good footage when they were on ISS. It is a shame however that this trailer doesn’t have English subtitles, because I think it probably could make some money from American filmgoers.
Pushback: Court denies school principal immunity from lawsuit for squelching free speech
Former school principal Caroline Garrett
Pushback: A federal appeals court last week ruled that Caroline Garrett, the former principal of Wy’east Middle School in Portland, Oregon, does not have immunity from a lawsuit by a teacher, Eric Dodge, whom she threatened to punish for bringing a MAGA hat to several training sessions.
At the first training session with 60 participants, “fewer than five people complained, including the first presenter who was not a District employee,” and all trainings were completed without incident, according to the court records. “Clinton, Reagan, and Trump appointees coming together to affirm the First Amendment,” lawyer Gregory Conley tweeted in response to the ruling, referring to the panel of judges.
According to the court’s official ruling [pdf], Garrett threatened to punish Dodge if he brought the hat into school again:

China releases first update on status of Yutu-2 since September
Click for full image. The red flag marks the landing site.
China today released its first update since September on the status of its Yutu-2 rover on the far side of the Moon. The map on the right shows the rover’s travels through December 2022.
As of today the rover has traveled 4,774 feet total, and about 450 feet since September. The goal, as stated in April 2021, was to “move northwest toward the basalt distribution area located about 1.2 km away.” At the time the rover was only averaging about 100 feet travel per lunar day. According to these numbers, it picked up the pace in the past year, though it is unclear whether it has reached that goal.
The soft icy Martian northern lowland plains
Click for full image.
In a cool image post last week, I noted that the near surface “ice sheets in the northern lowland plains are never … smooth, even if well protected.” The picture to the right, cropped, reduced, and sharpened to post here, provides an excellent example. It was taken on November 2, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
It is winter, and the sunlight is coming from the southwest, only 27 degrees above the horizon. The mound on the left is soft, while the depression on the upper right appears to have sand dune ripples sitting on top of a flat glacial mound. This depression may be an eroded crater (no upraised rim) or it could be a sink caused by the sublimation of the near surface ice.
Everywhere else the flat plains are stippled with small knobs.
The overview map below provides more context.

Largest volcanic eruption in years detected on Io
Using instruments on a ground-based telescope, one scientist based at the Planetary Science Institute (PSI) in Arizona has detected the largest volcanic eruption in years on the Jupiter moon Io.
PSI Senior Scientist [Jeff] Morgenthaler has been using IoIO, located near Benson, Arizona to monitor volcanic activity on Io, since 2017. The observations show some sort of outburst nearly every year, but the largest yet was seen in the fall of 2022. Io is the innermost of Jupiter’s four large moons and is the most volcanic body in the Solar System thanks to the tidal stresses it feels from Jupiter and two of its other large satellites, Europa and Ganymede.
IoIO uses a coronagraphic technique which dims the light coming from Jupiter to enable imaging of faint gases near the very bright planet. A brightening of two of these gases, sodium and ionized sulfur, began between July and September 2022 and lasted until December 2022. The ionized sulfur, which forms a donut-like structure that encircles Jupiter and is called the Io plasma torus, was curiously not nearly as bright in this outburst as previously seen. “This could be telling us something about the composition of the volcanic activity that produced the outburst or it could be telling us that the torus is more efficient at ridding itself of material when more material is thrown into it,” Morgenthaler said.
The material released by this eruption could impact Juno during future close approaches of Jupiter.
SpaceX raises another $750 million in private investment capital
SpaceX has just completed another round of fund-raising, gaining another $750 million in private investment capital.
This additional money now means that SpaceX has raised about $10 billion in private money, most of which is being used for the development of Starship and Superheavy. When we add the $4 billion SpaceX will get from NASA for Starship, the company now has $14 billion to build this new rocket.
SpaceX starts 2023 with first launch of year
SpaceX today opened the 2023 launch race with first launch of year, using its Falcon 9 rocket to place 114 satellites into orbit, most of which are smallsats.
The first stage completed its 15th flight, landing safely at Cape Canaveral. As of this writing deployment of the many smallsats is ongoing.
On the radio plus under the weather
Two things:
1. I will be on the Space Show with David Livingston tomorrow night for about two hours, beginning at 7 pm (Pacific). You can listen to it here. Please consider calling in. Conversations and questions are always fun.
2. I am a bit under the weather today, so it is likely I will not have the energy to do a blacklist column today or a cool image. This could change, as I get restless if not active. Regardless, I want to take some pressure off by making it voluntary, not a requirement for the day.
Hakuto-R successfully completes second mid-course correction
Hakuto-R’s planned landing site is in Atlas Crater.
According to Ispace, the private lunar lander company based in Japan, its Hakuto-R lander has now successfully completed second mid-course correction, and is functioning as expected on its way to the Moon.
The maneuver was carried out shortly after midnight on Jan. 2, 2023 (Japan Standard Time) and operations were managed from ispace’s mission control center located in Nihonbashi, Tokyo. This orbital control maneuver is the second maneuver to occur while the lander has been traveling to the moon. The first orbital control maneuver was completed on December 15, 2022. The second maneuver was carried out at a greater distance from Earth and lasted for a longer period than the first maneuver, verifying the company’s capability to carry out orbital maneuvers under various conditions.
As of Jan. 2, 2023, the lander has traveled approximately 1.24 million kilometers from the Earth and is scheduled to be at its farthest point of approximately 1.4 million km from the Earth by Jan. 20, 2023. Once the lander reaches its farthest point from Earth, a third orbital control maneuver may be performed, depending on its navigational status.
While Hakuto-R carries a number of commercial payloads — including Rashid, the first lunar rover built by the United Arab Emirates (UAE) — its primary goal is engineering. Ispace is using this mission to demonstrate its ability as a company to do this, in anticipation of later commercial planetary missions.
Pushback: University eliminates “bias reporting” option that allowed any student to anonymously squelch dissent
An afterthought at Southern Utah University
Bring a gun to a knife fight: After receiving a threat of legal action [pdf] for violating the first amendment rights of its students, South Utah University (SUU) eliminated a “bias reporting” option on its website that allowed any student to anonymously squelch dissent, simply because he or she did not like what the other person said.
Southern Utah University (SUU) removed a tab from its campus safety website where students and officials could report alleged “bias” or “hate” incidents after the Southeastern Legal Foundation (SLF), a non-profit legal group, challenged that it violates students’ rights to free speech, SLF confirmed to the Daily Caller News Foundation.

A spray of Martian hollows
Click for full image.
Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 12. 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed simply as a a “terrain sample” by the science team, the picture was not taken as part of any specific research project, but instead to fill a gap in the orbiter’s shooting schedule so as to maintain the camera’s proper temperature. When MRO’s science team does this, they try to pick something in the area below that might be interesting. Sometimes they succeed, but often the features in the picture are nondescript.
The white line delineates the rim of a faint and very eroded small crater. Are the depressions that are mostly concentrated just to its south and east sinks or past impact craters? I haven’t the faintest idea. The overview map below helps to answer this question, but only partly.

Philippines issues warning about Chinese rocket debris from launch
Click for full resolution image.
UPDATE: A tweet from China shows that the strap-on boosters of this rocket crashed near homes in China, though no one was hurt.
Original post:
—————–
The Philippine government issued a statement yesterday warning the public about possible debris from the December 29th launch by China of its Long March 3B rocket.
The Philippine Space Agency (PhilSA) is recommending precautionary measures related to expected unburned debris from the Long March 3B rocket scheduled for launch today between 12:33 PM and 01:10 PM Philippine time from the Xichang Satellite Launch Center in Xichang, Sichuan Province, China. Upon confirmation of planned launch dates, PhilSA immediately issued an advisory to all relevant government agencies on the estimated drop zone area and proposed the issuance of appropriate warnings on air and marine access.
Based on the Notice to Airmen (NOTAM) issued by the Civil Aviation Administration of China (CAAC) to the Civil Aviation Authority of the Philippines (CAAP), expected unburned debris, such as the rocket boosters and payload fairing, is projected to fall within a drop zone area located within the vicinity of Recto bank, approximately 137 kilometers from Ayungin Shoal and 200 kilometers from Quezon, Palawan. The unburned debris is designed to be discarded as the rocket enters outer space. While not projected to fall on land features or inhabited areas within the Philippine territory, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone.
Though the drop zone avoided inhabited areas, it included regions where fisherman worked, and the flight path still flew over inhabited areas. The risk was extremely low, but it appears China also made no effort prior to launch to coordinate this situation with other governments, such as the Philippines. Its warning apparently arrived just before launch. Thus, there was risk that Filipino fisherman were in the drop zone at launch.
South Korea test flies a solid-fueled missile
South Korea has successfully completed the second test flight of a solid-fueled missile.
The test came after North Korea claimed earlier this month to have staged a test of a “high-thrust, solid-fuel” rocket motor to develop a “new-type” strategic weapon system.
…In March, the state-run Agency for Defense Development carried out the first test of an indigenous solid-fuel space rocket at a testing site in Taean, 150 kilometers southwest of Seoul, to confirm its capabilities.
The rocket is designed to put a small satellite into a low Earth orbit for surveillance operations. Compared with liquid-fuel space vehicles, solid-fuel ones are known to be usually simpler and more cost-effective to launch.
South Korea might claim this rocket is intended for launching smallsats, but its main purpose almost certainly is as a military missile to counter the missile program of North Korea that has accelerated since Joe Biden became president.
SpaceX successfully launches Israeli imaging satellite
SpaceX today successfully launched an Israeli Earth-observation satellite, using its Falcon 9 rocket.
The first stage successfully completed its eleventh flight, touching down softly at SpaceX’s facility at Vandenberg Space Force Base.
This launch completes SpaceX’s 2022 launch year, with a record 61 launches, one more than predicted by the company earlier in the year, and the most ever by a privately owned company.
The leaders in the 2022 launch race:
62 China
61 SpaceX
21 Russia
9 Rocket Lab
8 ULA
The U.S. now leads China 85 to 62, while trailing the rest of the entire world combined 94 to 85. The 85 launches for the U.S. is a new record for a single year, smashing the record of 70 launches set in 1966.
On Monday I will publish my annual full roundup of the state of global launch industry, based on the 2022 numbers.

- SpaceX applies to build five new mega-gateway ground stations for its upgraded Starlink satellites
Soon thereafter, SpaceX applied for an additional eighteen. All 23 will be in the U.S., thus significantly enhancing access to its Starlink constellation for American customers. It also appears the company is building at least one gateway in the United Kingdom.
- Rocket Lab’s second launch out of Wallops is already being prepped
The first Wallops launch was delayed until January due to red tape. The company now plans back-to-back Wallops launches. It also plans to continue a launch pace of one launch per month for 2023.
