Wait-a-Minute!

Here’s a wait-a-minute question: What’s the frequency, Kenneth Arnold?
Admittedly, I borrowed and bent that R.E.M. song line. But it came to me in reading the latest outpouring of Unidentified Anomalous Phenomena (UAP) documents, videos and illustrations by the Department of War on August 7.
Those files are part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).
It’ll take a while before Unidentified Flying Object (UFO) and UAP specialists deep dive through all the newly released data.
But one thing caught my wandering and wondering eye.
Project Sign
I sifted through 245 pages of the report DOW-UAP-D100, Air Materiel Command Report on Unidentified Flying Objects, 1947-1948.
This file is a collection of U.S. Government memoranda and correspondence relating to “Project Sign,” a 1948 U.S. Air Force program to investigate reports of high-performance airborne objects.
The Air Materiel Command’s (AMC) investigation found that observers were “generally not mistaken when reporting that they had seen an airborne object, but that their characterizations of those objects as unusual was likely a reflection of the ‘limits of their personal experience.’”
Flying saucer
I thought 1947. Wasn’t that the year Kenneth Arnold caught glimpse of nine unidentified flying objects near Mount Rainier, moving at incredible speeds. What’s more is that Arnold’s report locked into place, due to a reporter’s catchy expression, the term “flying saucer.”
Indeed, on June 24, 1947, Kenneth Arnold was flying near Mount Rainier, Washington. He estimated the objects were flying at speeds of at least 1,200 miles per hour. His sighting is often cited as kick-starting the modern UFO phenomenon. That was over 79 years ago.
What I didn’t realize was that Arnold was not alone in sighting strange things in the air in 1947.

Typical reports
“The following are typical reports of observations of discs,” explains the AMC report, indicating the types of objects gleaned from a variety of sources.
On July 7, 1947, five Portland, Oregon police officers saw varying numbers of discs flying over different parts of Portland.
On July 7, 1947, a Phoenix, Arizona resident saw a disc in the glow of sunset and took two photographs. “The resultant picture showed a round front and square tail in plan form,” the AMC document adds.
On July 10, 1947, a mechanic near Harmon Field, Newfoundland, observed a circular object flying at high velocity and leaving a trail. Two other persons also saw the trail.
On July 11, 1947, three people at Codroy, Newfoundland saw a disc flying at high velocity and leaving a smoke trail.
Also pointed out in the AMC report, Kenneth Arnold’s sketch of one of the flying objects he spotted “corresponds closely to that shown in the photographs made by the individual in Phoenix, Arizona.
Furthermore, the AMC report states that on the same day as Arnold’s sighting, two U.S. Air Force pilots at Hamilton Field, California saw two flying discs trailing a P-80 aircraft, following it toward Oakland, California. The Lockheed P-80 Shooting Star was an early jet fighter.

Flying wing – German style?
This AMC report is chock full of other 1947 accounts of objects, from military personnel, including radar technicians in Japan.
In the “investigations made” part of the document, one item is looking into the possible existence of foreign aircraft projects which might be related to these observations. “Of interest in this regard are two German designs that could be under current exploitation by the U.S.S.R” – now the Soviet Union.
The Horten Brothers are identified as looking into a flying wing, crescent shaped in design.
Cannot be dismissed
In the AMC “conclusions” section, they state that “while a portion of the observations may be the results of natural phenomena, such as meteors, or may have other conventional explanation, the likelihood that some observers actually saw disc-shaped objects sufficiently large to be compared in size with known aircraft cannot be dismissed.”
“Considering the described conduct of these disc-like objects when sighted, it must be considered a possibility that they may have been humanly controlled, either manually or remotely, or by pre-set automatic controls,” the AMC report states.
Puzzling problem
Lastly, the AMC document explains that “if these discs actually exist they are foreign in origin, so investigation of the possible country of development and the place of origin should continue.”
All in all, the Directorate of Intelligence, U.S. Air Force, “will continue to collect and analyze all reports of sightings of flying objects, lights, trails, etc., in an effort to develop an answer to the puzzling problem which they present.”

Taking LEO Off the Board: Russian Thinking About Anti-Satellite Warfare is authored by Aaron Stein, President of the Foreign Policy Research Institute (FPRI).
“The Soviet Union and Russia have invested in anti-satellite weapons to ensure that their nuclear deterrent remains credible. For both the Soviet Union and Russia, the destruction of American satellites was (and is) viewed as part of the country’s broader nuclear war plan and part of the opening salvo in a nuclear conflict with the United States,” Stein writes.
Spurred by an influx of spending for the upcoming Golden Dome space-based interceptor architecture, Stein points out that “Russian planners are increasingly incentivized to further bypass traditional treaty norms and leverage co-orbital nuclear weapons to achieve a catastrophic mass-kill of low-earth orbit tracking networks and space-based defenses.”

Stein explains that the future is certain to feature a more militarized space domain.
For Stein to “take LEO off the board,” means that Russia could leverage a nuclear weapon to mass kill commercial satellites, including US space-based missile defense.
For sure such a tactic would also harm Russian satellites.
“However, given the rapid expansion of targets, the redundancies the US is now building, and the decreasing cost of launch,” Stein observes, “Russian strategists are thinking about how to negate these advantages. The urgency is certain to continue, as the United States continues to explore and invest in space-based missile defense.”

A Chinese research team has completed an updated geologic map of the entire Moon featuring a scale of 1:5 million.
China’s Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS) detailed the geologic map on August 6.
Beyond its scientific data, the 2.8-by-1.2-meter map introduces a proprietary cartographic standard that identifies over 13,500 impact craters and 81 basins.
“This standard will be extended to future planetary geologic mapping, establishing an independent intellectual property framework for China’s deep space exploration,” said Yang Zhiming, director of the IGCAGS.
Rewriting geologic history of the Moon
Yang said the newly-released lunar map represents a significant scientific iteration from the 2024 version, adding that the map effectively rewrites the Moon’s geologic history based on the latest research findings.
“The lunar geologic history has indeed been rewritten — more precisely, refined and systematized,” said Yang.

State-run Xinhua news agency reports that the new map “systematically updates the age boundaries of the Moon’s three ancient geologic periods, namely the Aitkenian, Nectarian and Imbrian periods, drawing on recent advances in international chronology.”
Return samples
Xinhua also adds that the Chang’e-5 returned to Earth samples confirmed volcanic activity on the Moon as recently as 2 billion years ago. Also highlighted were the findings from China’s Chang’e-6 return sample effort.
“The lunar samples and this map will provide a new starting point for scientific discussions regarding the lunar far side,” said Jin Ming, an associate researcher at the IGCAGS.

The dispersion of launch costs has shrunk over the years. A new paper noted that three effects could be causing this phenomenon.
- Historically it has been documented how there is a high degree of trial and error in the early application of technologies, leading to a wide dispersion in productivity outcomes.
- Space exploration began in a Cold War era and was dictated by the objective of showcasing scientific advancements. As a consequence, launch costs were a secondary concern, especially with respect to reliability. Spacefaring nations would want to launch using their home-based rocket technology irrespective of the cost.
- Starting in the 1980s, the private sector has become interested in placing its own satellites in space, predominantly for telecommunication purposes. Evidently, this has progressively led to a shifting focus toward profitability and cost minimization.

Geopolitics and space access
Also, go to this companion research that highlights the following points:
- US launch costs are now over 3x cheaper than European ones.
- The US accounts for over 80% of global payload to orbit in 2025.
- Only the US and Europe display a space launch experience curve.
- Cost asymmetries reinforce strategic dependencies with security implications.

The Korea Aerospace Administration (KASA) has released the lunar impact observation data acquired by the country’s Moon-orbiting Danuri spacecraft.
Danuri captured images of the pre-hit scene and after the impact of the roughly 4 ton upper stage of a SpaceX rocket.
The upper stage of the SpaceX Falcon 9 rocket struck the area near the lunar ‘Einstein Crater’ at around 3:34 p.m. on the 5th (Korean time).
Imaging sessions
Danuri conducted an initial imaging session about 30 minutes before the impact, and then carried out an additional seven imaging sessions after the impact.
All spacecraft imaging was completed at around 7 a.m. (Korean time) on August 6.

Imagery taken show changes in the lunar landscape near the impact site and traces of ejecta tossed onto the surface.
Using the orbiter’s ‘high-resolution camera (LUTI), researchers confirmed the surface changes.
Danuri’s ‘wide-angle polarimetric camera (PolCam)’ also imaged the same region.
Researchers plan to analyze how the reflection and polarization properties of light from the lunar surface changed before and after the impact.
Next flyover: LRO
NASA’s Lunar Reconnaissance Orbiter (LRO) is will pass over the impact region on August 11, Mark Robinson of Intuitive Machines in Phoenix, Arizona told Inside Outer Space. He serves as the principle investigator for the NASA Lunar Reconnaissance Orbiter Camera and also the PI for the NASA lunar imaging experiment ShadowCam onboard Korea’s lunar orbiter.
Close conjunction
Interestingly, there was the prospect of a worrisome close conjunction of the Falcon-9 upper stage and Korea’s Danuri lunar orbiter.
“We noticed roughly late June that there is an incoming Falcon-9 upper stage toward the Moon, and also knew that it would be close to Danuri,” Eunhyeuk Kim, a senior researcher at the Korea Aerospace Research Institute (KARI) told Inside Outer Space.
There was a huge uncertainty in the predicted trajectory of the moon-bound rocket state, while the orbit information of Danuri was quite accurate, Kim added. Therefore, operators of Danuri could not neglect the probability of an incoming and close encounter.
However, around mid-July, the KARI/Danuri team made a maneuver of the spacecraft for the preparation of a near-total lunar eclipse on August 28. Kim said this maneuver brought a slight change in the phase of the spacecraft’s orbit, which canceled the probable conjunction between Danuri and the SpaceX Falcon 9 rocket stage.

Reports Jose Maria Madiedo at the Astrophysics Institute of Andalusia (IAA-CSIC), they obtained video of the impact of the Falcon 9 stage on the Moon. “Note that the impact occurred just behind the Moon’s limb as seen from Earth, so we only see the dust cloud rising beyond the limb. The impact zone is invisible.”

Scientists at the Lowell Observatory in Flagstaff, Arizona report they detected a plume from the impact August 5 from that errant SpaceX rocket stage.
“We can safely say that we measured a response from the rocket stage impact as a sodium and lithium gas plume a few 10’s of kilometers in size lasting between 5 and 10 minutes after impact,” Carl Schmidt tells Inside Outer Space.
Schmidt is an assistant research professor at Boston University’s Center for Space Physics.
Schmidt said that his early analysis of what was observed is early and crude, “in order to recover a signal quickly.” Graduate students, he added, “are working slowly and carefully” on the data.
Two efforts
There were two efforts to observe the event at Lowell Observatory. One using fast imaging to record the brief light from the fireball, predicted to last a fraction of a second.
Observers at the 4.3-meter Lowell Discovery Telescope (LDT) in Happy Jack, Arizona, were also to use a long slit spectrograph to try and measure the sodium gas plume which was anticipated to persist for several minutes.
LDT is the 5th-largest optical telescope in the United States.

Unknown unknowns
The event was a literal “dust up” on the lunar landscape.
That Falcon 9 upper stage was a leftover from the launch that sent Firefly’s Blue Ghost-1 lander to the moon on Jan. 15, 2025. Also sent moonward on that flight was the Hakuto-R Mission 2, called Resilience, a robotic lunar lander developed by the Japanese company ispace.
The rocket stage collision on August 5 was pegged to occur near Einstein/Bell Craters near the lunar limb. What was not known: would the event be visible by ground and space-based assets.
Despite all the unknown unknowns, and modeling uncertainties, some specialists suggested if you’ve had the time and observational prowess, it was worth a look.
Such was the case for the Lowell Observatory.

Planting boots on Mars is hard enough. But getting “breathing room” on the Red Planet without inhaling toxic dust is yet another issue.
Given the outlook that future human crews will strut their right stuff across the Red Planet, NASA assembled earlier this year a Martian Dust Limit Working Group. Their task was to review what’s known and unknown about the toxicological hazard to human crews from exposure Mars dust.
Permissible exposure limit
That review was made to support the establishment of a permissible exposure limit for humans on the Red Planet.
The working group compiled a comprehensive set of expert perspectives regarding Martian dust toxicology, exposure pathways, and mitigation strategies.
Lunar dust haunted Apollo moonwalkers, termed the “dusty dozen.”
