SpaceX Launch

The Damsel and I went out in the courtyard at about six-forty P.M. to observe the waning sunset and the waxing crescent Moon. We were surprised to see what appeared to be a rocket trail to the west. A little research in the smart phone revealed that there was indeed a launch from Vandenberg in California which was clearly visible from our courtyard. I took the image above with the phone’s camera which seems to have done a pretty good job of recording what we were seeing. Clickable image.

Details from Grok:

SpaceX Starlink Group 11-21 Launch from Vandenberg Space Force Base

On October 27, 2025, SpaceX conducted a successful Falcon 9 launch from Vandenberg Space Force Base (VSFB) in California, deploying 28 Starlink V2 Mini satellites to low-Earth orbit (LEO) as part of Group 11-21. This mission marks the company’s sixth Falcon 9 launch from VSFB in October 2025 alone, contributing to a record pace of operations at the site. The launch highlights SpaceX’s ongoing expansion of its Starlink mega-constellation, aimed at providing global broadband internet coverage.

A live webcast was streamed on SpaceX’s official X account and website, starting about 5 minutes before liftoff, attracting thousands of viewers.

No anomalies were reported post-launch, and the mission was deemed a full success. SpaceX’s next VSFB launch is slated for October 30 at 1:06 p.m. PDT with another 28 Starlink satellites. For real-time updates, follow @SpaceX on X.

We have seen rocket trails in the past from various locations, but this was the first seen from our house in the desert.

Lunar Landings — Hoax or Real?

Earlier today, I watched a You Tube video purporting that the NASA and USA Lunar landings were possibly fake. I asked GROK to clarify this issue, since I was very active in aerospace in my career and found the space exploration to be genuine and not a subterfuge.

Here is what I got from the Grok AI:

The idea that NASA faked the Moon landings, particularly the Apollo missions from 1969 to 1972, is a well-known conspiracy theory. It suggests that the United States never sent astronauts to the Moon and that the evidence—photos, videos, and lunar rocks—was staged or fabricated. Below, I’ll outline the main claims of the conspiracy theory, the evidence supporting the Moon landings, and a reasoned perspective on why the theory persists, while keeping the response concise and grounded.

Main Claims of the Moon Landing Hoax Theory

Conspiracy theorists point to several perceived inconsistencies or anomalies to argue the Moon landings were faked:

  • Waving Flag: The American flag planted on the Moon appears to “wave” in videos, which some claim suggests wind, impossible in the Moon’s vacuum.
  • Missing Stars in Photos: Photographs taken on the Moon don’t show stars in the background, leading some to argue the images were staged in a studio.
  • Lighting and Shadows: Shadows in lunar photos appear inconsistent, with some claiming multiple light sources (like studio lights) were used instead of the Sun.
  • Van Allen Radiation Belts: Critics argue that astronauts couldn’t have survived the radiation in the Van Allen belts during transit to the Moon.
  • Lack of Independent Verification: Some claim that no independent observers, like amateur astronomers, saw the spacecraft on the Moon.
  • Motivation for Fakery: Theorists suggest NASA faked the landings to win the Space Race against the Soviet Union, boost national pride, or justify budgets.

The AI responce goes on to address the concerns about the supposed inaccuracy of the landings given the photos and everything available:

Evidence Supporting the Moon Landings

The Apollo program’s authenticity is backed by extensive evidence, which directly addresses the above claims:

  1. Waving Flag: The flag’s movement is explained by the lack of atmosphere on the Moon. In a vacuum, there’s no air to dampen motion, so the flag, disturbed by astronauts, appears to “wave” as it settles.
  2. Missing Stars: Stars aren’t visible in photos because camera exposures were set for bright lunar surfaces. Long exposures needed to capture faint stars would overexpose the foreground, a standard issue in photography.
  3. Lighting and Shadows: Shadows appear unusual due to the Moon’s reflective surface and lack of atmospheric scattering. The Sun was the primary light source, and uneven terrain or reflected light from the lunar surface explains shadow variations. NASA’s detailed analysis, including 3D modeling, confirms consistency with a single light source.
  4. Van Allen Belts: Astronauts passed through the belts quickly, receiving minimal radiation exposure—equivalent to a few medical X-rays. NASA’s shielding and trajectory planning minimized risks, as confirmed by dosimeter readings from the missions.
  5. Independent Verification: Lunar rocks brought back (382 kg from Apollo) have unique chemical signatures, like anorthosite, consistent with lunar origin and distinct from Earth rocks. These have been studied by scientists worldwide. Additionally, the Soviet Union, a rival, never disputed the achievement, and retroreflectors left on the Moon (still used for laser ranging experiments) were detected by observatories globally.
  6. Scale of Conspiracy: Faking the landings would require silencing thousands of NASA employees, contractors, and scientists, plus coordinating with international observatories and even adversaries like the USSR. The logistical complexity makes this implausible.

The next part of the response from the GROK AI goes on to refute additional concerns thus concluding the landings were actual:

Additional Evidence

  • Apollo Mission Data: Over 800,000 photos, hours of video, and detailed telemetry data from Apollo missions are publicly available. Independent analysis, including by modern AI and imaging experts, shows no signs of tampering.
  • Third-Party Observations: Soviet tracking stations monitored Apollo spacecraft, and amateur radio operators picked up signals from the Moon. India’s Chandrayaan-2 and China’s Chang’e missions later photographed Apollo landing sites, confirming hardware presence.
  • Human Testimony: Over 400,000 people worked on Apollo, and 12 astronauts walked on the Moon. No credible whistleblower has emerged, despite the conspiracy’s claim of a cover-up.

Why the Theory Persists

The Moon landing hoax theory persists due to cognitive and cultural factors:

  • Distrust in Institutions: Skepticism toward government and large organizations fuels belief in cover-ups, especially post-Watergate and during times of political mistrust.
  • Media Influence: Films like Capricorn One (1977) and books like Bill Kaysing’s We Never Went to the Moon (1976) popularized the idea, despite lacking evidence.
  • Cognitive Bias: Anomalies in complex data (e.g., photos) are often misinterpreted by laypeople unfamiliar with lunar physics or photography. Confirmation bias leads believers to dismiss counterevidence.
  • Cultural Impact: The theory resonates because the Moon landings were a monumental achievement, hard for some to accept as real, especially given their scale and historical context.

So, the GROK AI, being a thing from the SpaceX world goes on to reference some posts from the X (formerly Twitter) platform and does its own conclusions and teaser for more info:

Recent Context from X

Posts on X reflect ongoing debate. Some users cite the usual claims (e.g., flag waving, shadows), while others share NASA’s rebuttals or memes mocking the theory. A few posts reference modern lunar missions (e.g., China’s Chang’e) confirming Apollo sites, though skeptics on X often dismiss these as part of a broader conspiracy. The platform shows a mix of staunch believers and debunkers, with no new evidence emerging to support the hoax theory.

Conclusion

The Moon landing hoax theory relies on misinterpretations of visual evidence and underestimates the overwhelming physical, scientific, and historical evidence supporting the Apollo missions. The theory thrives on distrust and the human tendency to seek patterns in complex data, but no credible evidence supports it. The Apollo program remains one of humanity’s greatest achievements, backed by data from NASA, independent scientists, and even rival nations.

If you want me to dive deeper into any specific claim (e.g., analyze a particular photo or radiation data) or check X for real-time sentiment on this topic, let me know!

So, as you may have surmised, I’m having a bit of fun with the AIs that are available out there. Everything from Lunar landings (this article) to finding ancestors. And more to come, I’m sure.

Starlink Mini Performance Report

We live in sort of a low hollow area in our semi-rural desert home with rising terrain to the north and a couple of places towards the southwest. Even under conditions of placing the Starlink Mini dish on the roof of the house, we would have a limited view of the sky. That being said, I did not want to climb up on the roof to put the dish up there, so I placed it on the spa in the Arizona Room (screened-in patio) by the RV Drive behind the house. Due to the limited sky view from the patio, the Starlink App reports the following 3-D graphic of the obstructions the unit “sees.”

The “dish,” in reality, is a planar phased array antenna which scans the sky for satellite signals and plots the areas blocked by obstructions. The App admonishes that the map of obstructions is collected over several hours and should be stable-ish after a while. The map shown has been integrated over the last day or so with the current antenna placement. Blue equals clear sky shot and red is obstructed. The white square is the antenna. I estimate clear sky to be no more than 35-40 percent of the dome. Regardless of the overwhelming obstructions, the system can deliver the performance seen in the OOKLA download rate seen below.

That rate is sufficient to do most internet streaming services, but may not perform as well for interactive gaming or other similar stuff for which we have no need. There is a caveat on the megabit performance shown; the satellite constellation is on the move and the performance (rate) may suffer as things go in and out of range, so some buffering (delays) may be possible.

Another note of interest: during the past few weeks, our Cox Internet Cable has gone down for several hours at a time. With the (approximate) setup shown in the top image, we continued internet service in spite of the outages on the cable.

We should do OK on the road with all of our internet needs as we take off for a nice long RV excursion in a few weeks.

This is not a paid plug, but I notice that the Starlink Mini is on sale for 40 percent off or so ($299 vs $499).

SpaceX Satellite Launch

SpaceX Satellite Launch

As Damsel and I were relaxing last evening, we were startled by a knocking at the back porch. It was the UPS delivery guy with a package we ordered from Amazon. But the package drop-off wasn’t the end of it. The driver said “Come out here and look at this!”

We walked down the driveway looking west and we pretty much saw the image depicted above, although we’re in a darker location than the Phoenix area where the photo was taken.

The phenomenon was attributed to a SpaceX Iridium Satellite launch:

At 5:30 pm on Dec. 22nd, SpaceX launched a 2-stage rocket from Vandenburg Air Force Base near the California coast.

The rocket launched 10 communications satellites to low-Earth orbit, adding to the growing Iridium NEXT constellation. This is the fourth such mission that SpaceX has flown for Iridium. Moreover, the rocket used for this mission had been used before. The Falcon 9 previously flew in June for the second Iridium mission.

It was quite spectacular as we watched the rocket move across the sky with its trail of gas lit up by sunlight high in the atmosphere. We’re glad that the UPS guy alerted us to this unusual event.

Cassini: The Grand Finalé

Cassini Spacecraft

Early yesterday, I awoke to news that the 20-plus year mission of the Cassini Saturn-probe spacecraft has come to an end. The durable spacecraft, launched in 1997, had more than tripled its four-year scientific mission’s original timeline plan. Early on September 15, 2017, the spacecraft executed it last command to dive into the atmosphere of Saturn and disintegrate.

Since Cassini arrived on station thirteen years ago, we watched the marvelous discoveries and monitored the experiments performed with eager anticipation to see what new facts about the Saturnian system of moons, rings and the planet itself might be revealed. We were not disappointed.

So, adios to Cassini. We look forward to seeing the next explorations planned not only by NASA/JPL, but also by other commercial space exploration entities.

There is considerable information about the now completed mission at the Cassini Grand Finalé toolkit page.

ISS and SpaceX Dragon Sighting

SpaceX Dragon

One of our regular activities in retirement in our desert place is to watch for overflights of The International Space Station when they are visible. Tonight’s flyover was the last in the current series of visible passes in our area and included a special treat of which we were unaware until after the pass.

As the ISS soared across the sky, Damsel noticed a fainter speck of light following in trail of the brighter space station. We both saw it and wondered what it could be. I suggested that it might be a cargo resupply or something of the sort. We continued to watch the pair as they swooped out of sight towards the southern horizon.

I came back in the house and got on the computer to see if I could find out what we were seeing. It turns out that the fainter dot of light was a SpaceX Dragon CRS-12 resupply ship with 6400 pounds of “stuff” on board to deliver to the ISS on Wednesday morning.

This is from the NASA blog about the SpaceX Dragon Launch:

Crew members aboard the International Space Station can expect a special delivery Wednesday morning. A SpaceX Dragon spacecraft loaded with more than 6,400 pounds of supplies, equipment and science materials is heading their way after the successful liftoff of SpaceX CRS-12 at 12:31 p.m. EDT from NASA Kennedy Space Center’s Launch Complex 39A.

The on-time liftoff marked a spectacular conclusion to a countdown that proceeded like clockwork throughout the morning, aided by cooperative weather conditions across the launch site. With a sonic boom sounding across Florida’s Space Coast, the first stage returned to SpaceX’s Landing Zone 1 on Cape Canaveral Air Force Station while the rocket’s second stage finished the task of propelling Dragon to orbit.

Read more at the link above the quote. Damsel and I feel very fortunate to have witnessed this extraordinary extra-terrestrial event.

Damsel remarked earlier this evening regarding that she’s glad to see SpaceX, rather than Russians, supplying the ISS these days. I wholeheartedly agree with that.

May 9, 2016 Transit of Mercury

My efforts to photograph the Mercurial transit of the sun today were less than optimum; the diminutive disk of the small planet did not resolve well with my Canon SL1, 300mm lens and a $10 solar filter. Moreover, looking at the sun through Eclipse Shades was a bust; you couldn’t resolve the planet at all.

But, all was not lost – thanks to the Solar Dynamics Observatory’s images on the internet, I captured several screen shots to combine into the animation below. The sequence starts when Mercury is almost at mid-transit (I did not want to get up at 4 AM) and continues to the point where the shadow is barely touching the east limb of the sun. I find it very interesting that the sunspots at and above the equator move to indicate the solar rotation over the few hours it took for the transit.
