We've never seen anything like this recording of a landing on another world. @Firefly_Space

This art is so cute that I have to translate it 😍

The world has a new Lando who’s shown he’s fast enough to outrun a fireball.

Here we go! NASA M2M WSA-ENLIL+Cone model indicates a direct hit, as expected. The estimated speed is 905 km/s, close to my guesstimate/ballpark estimate. Arrival time is early on December 9th (~4-5h UTC). Potentially capable of generating a significant geomagnetic storm.

Scientists have developed a new ultra-black fabric, so now goths have a new blacker colour of black to add to their wardrobes. https://t.co/VA9yDe5JzJ

In case you ever wondered what it would be liked to be engulfed in a lava fountain... This video was recorded by the V3 camera, located on the south rim of Halema‘uma‘u crater at the summit of Kīlauea volcano on the Island of Hawai‘i. The camera, located in a hazardous closed

NASA’s supercomputer center began in Silicon Valley because that’s where the expertise was, and the expertise is still here, but those experts can get a massive pay rise by crossing the street to work at a tech company. And those tech companies put datacenters elsewhere in the US

Jared's NASA plan 'Project Athena' asks whether NASA needs in house high performance computing, meanwhile when I visited NASA Ames they mentioned the next supercomputer they're building is named 'Athena'

This is NOT a comet, not even a meteor, but the planet Mercury. In early December 2025, Mercury can be spotted in the morning sky shortly before sunrise, low on the eastern to southeastern horizon. How is the tail formed? Solar wind and micro-meteorite impacts eject sodium

This fleeting red flash above a thunderstorm cloud is one of Earth's most elusive electrical phenomena! They're called sprites! Fun fact: This image was captured by citizen scientist Nicolas Escurat through the citizen science project Spritacular. ✨

3D printed air intact duct for planes, sure why not? Good read, aircraft crash caused by a 3d printed air intact duct, the CF-ABS part was "supposed" to have a GT of 105c but failed (in post crash) testing in the mid 50c range wonder if it was CF-PLA sold as CF-ABS

Here is Leslie Fish singing “Make This World Come Alive.” She wrote it for the Mars Society at my request. I worked with her on the ideas, but she wrote all the words and music. Then she sent me the original score. I still have it. https://t.co/kIyfAygmTa

I emailed a colleague who is a neutrino expert for an opinion. I won't say who it was, but this was the response: "They’ve killed—for the nth time—the existence of a sterile neutrino. Will this be the end of the sterile-neutrino saga? Of course not. Just wait. A fresh wave of

This is what it would look like before being zapped by the lasers. In the center of that gold cylinder is a 2mm sphere filled with Deuterium/Tritium

Here’s the remains of that target on display
