Rain woke me up in Pasadena. They predicted some chance of rain today, but it was strong rain for 20 minutes. Radar map from Apple Weather app.

The tragedy of Professor Jason Arday is being “weaponized” by the right against black academics in the UK and beyond. I found this opinion perspective in the Guardian helpful. https://www.theguardian.com/commentisfree/2026/aug/13/jason-arday-right-racial-equality-society
NASA-ISRO SAR (NISAR) satellite mission releases both L-band and S-band data. L-band is global coverage in new release on 20 July. S-band is for the Indian subcontinent and some additional areas, released on 15 July. See NASA press release with more details and “hummingbird” shape found in radar […]

Washington Post has an article today about debris in Low Earth Orbit (LEO), but it only covers the unintended debris from satellite destruction tests and other sources. It barely mentions the huge number of Starlink satellites only because they need to avoid the debris. Gift article link […]

They booked the killer for manslaughter, but this sounds more like vehicular homicide to me. "..Rapp and a fellow bicyclist were riding on a local road when Medina passed them in his car, stopped, and drove his vehicle in reverse. Medina then hit Rapp.." […]

The NASA-ISRO SAR (NISAR) satellite imaged Venezuela on June 25 with L-band (24 cm wavelength) synthetic aperture radar (SAR). The NISAR Urgent Response system was activated and made an interferogram (InSAR) with the previous pass on June 13. Colleague […] [Original post on mastodon.social]

It turns out that CBS Studios financed the Colbert episode of “Only in Monroe” and owns the copyright. The “volunteers” were paid after all. Variety magazine has the story: CBS Suspends Takedown Notices on Bootleg YouTube Uploads of Stephen Colbert's 'Only in Monroe' Public Access Show After […]

The City of Pasadena approved an organization to hire 600 goats to eat vegetation on the steep slopes of the Arroyo Seco and reduce wildfire risk. The pilot project was 100 acres (about 50 hectares). The goats finished their work much faster than expected. See this article in PasadenaNow […]

It's no secret that I've been struggling, and my therapist said I need to find things to keep me busy, so I created the @cdnspace Artemis II dashboard. I reverse-engineered the Unity Engine powering the NASA AROW visualization and found an absolute treasure trove of data to display. Little did […]

@sundogplanets Linda Geddes at The Guardian has a well-researched article about how Reflect Orbital’s space mirrors can damage the environment https://www.theguardian.com/science/2026/apr/05/satellite-mirror-plans-could-disrupt-sleep-and-ecosystems-worldwide-scientists-say
Satellite mirror plans could disrupt sleep and ecosystems worldwide, scientists say
Letters to US agency raise concerns over tech firm’s plans to use reflective satellites and expand numbers in low Earth orbit

Good morning #SFBA! If you slept through last night's #earthquake, still feel out the USGS survey. "I slept through it" is still a useful data point. https://earthquake.usgs.gov/earthquakes/eventpage/nc75337442/tellus #California #SanFrancisco
I saw southern auroras last night!!!! Rakiura! Holy cow that was AMAZING (View from a bit south of Arthur's Pass, New Zealand)
This WaPo article describes many signs of Trump’s dangerous derangement and unfitness, but in failing to state the obvious conclusion, it sanewashes his conduct. It uses “unique” as a pathetic euphemism for “chaotic and irrational“. It’s worse than nothing. www.washingtonpost.com/politics/202...
A wartime presidency defined by Trump’s unique political style
President Trump is recasting the role of wartime leader in his image, breaking from generations of practice as he attacks his domestic enemies and revels in memes.

I woke up to see the lunar eclipse, but we have clouds. Darn marine layer!
"Rocket launches already contribute to climate change and ozone depletion. Scaling them up to deploy a million aircraft-sized satellites would push upper-atmosphere heating and ozone loss far beyond previous estimates, with the steady burn-up of dead satellites compounding the impacts." 🧪🛰️🚀
A new space race could turn our atmosphere into a ‘crematorium for satellites’
Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

The NASA JPL robotics team found a way to use the commercial CPU (Snapdragon) in the Ingenuity helicopter base station on the side of the Perseverance rover to do advanced image processing on the imagery captured by the rover and determine the rover location on Mars accurately. Since it was not […]

@sundogplanets Maybe you saw this study of Amazon Leo satellite brightness. https://phys.org/news/2026-01-amazon-leo-satellites-exceed-brightness.html
Amazon Leo satellites exceed brightness limits, study finds
Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server has found that satellites from Amazon's mega Leo constellation (originally known as Project Kuiper) are bright enough to disrupt astronomical research.
