Stunning footage from earlier today, when the new Kilauea eruption covered the USGS Webcam 3, which is situated in the Halemaʻumaʻu crater near the southern rim of the much larger Kilauea caldera.

This *isn't* what the people of Pompeii saw.

But it's not very far off.

*This* is what the people of Pompeii, and Herculaneum, and many other hapless souls saw—this is what a pyroclastic density current looks coming RIGHT at you.

NASA Tests Drones in Death Valley, Preps for Martian Sands and Skies - NASA Next-generation drone flight software is just one of 25 technologies for the Red Planet that the space agency funded for development this year.

Several NASA projects are testing new ways to explore Mars. Death Valley sand dunes were used to test automatic navigation of drones over featurelesss areas of sand. www.nasa.gov/solar-system...

NISAR systematic data processing includes Level 2 geocoded data products that are Analysis Ready Data. The geocoded unwrapped interferograms (GUNW) are HDF5/NETCDF files that can be loaded directly into ArcGIS or QGIS and other analysis programs. Polarimetric data geocoded as GCOV HDF5 products

NISAR data will be available from NASA EarthData systems, including the Alaska Satellite Facility (ASF).

Yes, lapse in funding for the US government slowed the commissioning, but most work at JPL was funded in advance and continued.

Full science acquisitions started at beginning of November, but calibration and other commissioning activities are still underway so data release delayed until January

HiRISE Image of Exocomet 3I/ATLAS!

On 2 October 2025, MRO turned away from Mars to image 3I/ATLAS, only the third interstellar object ever observed passing through our solar system!

Interesting! Some of the arrows have different positions and directions in the old and new images.

The difference is now everyone has a tool for summarizing large volumes of text documents, the Large Language Models of ChatGPT and many others.

“Space Waste” – New Reports Underscore Impacts from Satellite, Rocket Body Reentries as an “Uncontrolled experiment”

Our National Parks are our “crown jewels.” Just one expert was plugging abandoned mines that leak methane and oil into these lands — until this administration let him go.

Their reckless cuts endanger Americans and create a new public health crisis.

FYI @rookisaacman.bsky.social is NOT an account run by Jared Isaacman or anyone associated with him. Yes, I checked.

Headline: Why Trump’s cuts to scientific research are a big win for China Subhed: China is attracting American scientific talent, especially in STEM fields, partly due to funding cuts and immigration restrictions under President Donald Trump.

This is what every single person with any experience in China has been warning about from the start.

Very good WaPo story by Katrina Northrop and Rudy Lu. www.washingtonpost.com/world/2025/1... And good, clear headline!

JVL and Sarah Longwell take on the absurd “Sandwich Guy” trial:

"Got the officer up there talking about how he felt the impact through his ballistic vest and there were onions and mustard everywhere. And the jury looked at this and said: get the fuck out of here." www.thebulwark.com/p/jury-acqui...

Toxic Wastewater From Oil Fields Keeps Pouring Out of the Ground. Oklahoma Regulators Failed to Stop It. Salt water laced with cancer-causing chemicals, a byproduct of oil and gas drilling, is spewing from old wells. Experts warn of a pollution crisis spreading underground and threatening Oklahoma’s drinking water.

NEW: Salt water laced with cancer-causing chemicals, a byproduct of oil and gas drilling, keeps shooting out of the ground in Oklahoma.

Experts say it means even more wastewater is spreading underground, poisoning the state’s water supply.

Hurricane Melissa developed into a major Category 5 hurricane and is poised to make landfall in Jamaica overnight, where catastrophic damage is expected, according to the US National Hurricane Center's forecast. Follow for the latest maps and forecasts reut.rs/3LbNFck

I am glad that I stopped using the former Twitter about two years ago.

The Landsat 4 remote sensing satellite was launched by NASA in 1982 and later operated by the commercial company EOSAT for NOAA and USGS until it was retired in 2001. It reentered over the China-Vietnam border area on Oct 8.

I worked with Landsat 4 data for my PhD thesis.

Last night, NASA's Perseverance rover looked up at the night sky once more, to capture interstellar #comet 3I/Atlas flying by the red planet.

The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth. 🔭 #3IAtlas

No Avi, that Perseverance Navcam picture you posted isn't showing 3I/Atlas, it's just Phobos, the brighter one of Mars' moons.

If you were even half the expert you think you are, this possibility should have been quite obvious and worth mentioning.

This is complete and utter pompous bullshit. It's telling that of the people proposing it wants to anoint themselves director general when every one of his claims of having discovered technosignature interstellar objects has been debunked by the planetary community. arxiv.org/pdf/2510.01405

I assume the Trump Administration found a way to pay the farmers for the food even if they did not deliver it to the food banks.

Mark Kelly: “lf you are undocumented in our country, you cannot get healthcare from the Affordable Care Act exchange. You are not eligible for Medicare. You are not eligible for Medicaid. They’re just making that up. They just like to blame brown people.”

Here are all the states Russ Vought announced just today he would be illegally stealing taxpayer dollars from.

Have we ever had a President work so hard to hurt the people he represents? I'm not going to be intimidated by these crooks.

Science Agencies Shuttered in Government Shutdown - Eos At 12:01 a.m. this morning, the U.S. federal government shut down. This shutdown comes after weeks of negotiations and pressure tactics failed to bring Congressional Republicans and Democrats together...

The government shutdown will halt some federal research at agencies already struggling with staff and funding cuts 🧪

NASA-ISRO Satellite Sends First Radar Images of Earth’s Surface - NASA The NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing radar satellite’s first images of our planet’s surface are in, and they offer a glimpse of

The first NISAR (NASA-ISRO SAR) L-band radar images now released! Early images acquired before NISAR reached the final science orbit. The mountains of Mount Desert Island in Maine, USA, are beautiful. I first visited Mount Desert Island with my family when I was small.

NASA's OPERA Project Releases Troposphere Zenith Radar Delays Dataset | NASA Earthdata This mission-agnostic dataset allows scientists to enhance airborne and spaceborne radar measurements by reducing the atmospheric noise that can obscure ground motion signals.

NASA’s Observational Products for End-Users from Remote Sensing (OPERA) project released the Troposphere Zenith Radar Delays (TROPO) dataset that allows InSAR users to reduce effects of atmospheric propagation delays for improved measurement of ground motion. www.earthdata.nasa.gov/news/nasas-o...
