Finding a million asteroids!
This is the handheld 400mm lens with 2x adapter (i.e. 800mm telephoto) I used for taking that image of Oshkosh from space.
In 2003 I was on ISS which was my excuse for missing @EAA Oshkosh that year. But I managed to get this photo cruising overhead at Mach 25 and Flight Level 12000. If you look carefully you can see at show center the smoke trail of Matt Chapman doing his airshow!
Years ago I flew into Oshkosh in a NASA T38 and ATC was unable to contact an arriving U-2. So I got to be the relay comm to the U-2 giving him clearance to land. Good times!
It’s a beautiful day for a U-2 arrival. 😉 (Especially when captured from above.) Dragonlady has made it to Oshkosh! #OSH25
Now this is a cool photo!
Just. Wow. As we went over Mexico and the U.S. this morning, I caught this sprite. Sprites are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below. We have a great view above the clouds, so…
We have a new interstellar object! We know because it is moving faster than the Sun's gravity could accelerate it to if it started from within the Solar System. Either that or it is aliens!
There's a new interstellar comet in the neighborhood! Known as 3I/ATLAS, this comet poses no threat to Earth – but it does provide a rare opportunity to study an object that originated outside of our solar system: science.nasa.gov/blogs/planetar…

Today is Asteroid Day, a reminder that large asteroids sometimes do hit Earth like we saw on June 30, 1908. And as the current stewards of Planet Earth, we can now prevent future impacts. @b612foundation is leading the way!
Rusty has done so much to protect the Earth from asteroid impacts. We all owe him a great big thanks!

The best round of wrestling is tonight! That's because everyone lets it fly. The semifinalists to get a spot in the finals, and the blood round guys to become an All American. These are the most exciting matches. Can't wait!
I know what I'm watching on TV for the next 3 days!
Tuned in? Let us know where you’re watching from! ⬇️ #NCAAWrestling25
I would love to visit my old home/office ISS again for a short stay! There have been many additions and upgrades over the years. It might feel crowded though. I flew as half of a crew of 2 people when the Shuttle was grounded after Columbia.
The hardest part about recovering from many months in space isn't the physical part (that is relatively easy). It is the administrative and paperwork things! getting my bills paid, safety inspection on car (I got a ticket), lawn cleaned up etc.
Instead of training LLM's on stuff on the internet, how about training a model just on physics and engineering textbooks? Is that large enough of a data set?
Thanks, and it is important that we are showing our work (see the Jupyter notebook so you can follow along).
This is a bonkers good tool & visualization of asteroid impact corridors (2024 YR4 down here). Comes with a Jupyter notebook letting one reproduce it in just 7 cells of code (link in 🧵). Kudos to the @b612foundation ADAM team (@astroEdLu , Alec, @moeyensj , Nate, Kat).
If you zoom in on the Moon in this interactive viewer, you can see how some of the trajectories are deflected by the Moon's gravity. We are working on calculating the impact probability on the Moon right now. @DJSnM
