Asteroid Institute, a program of B612 has taken the orbit and uncertainty of asteroid 2024YR4, sampled 10K trajectories from the current uncertainty, and propagated them forward. 2.3% of those hit the Earth on Dec.22, 2032. Here is where they hit.

Here are 70 clones of #asteroid 2024 YR4 that do hit Earth, highlighting the impact risk corridor. There are some big cities along that line: #Bogota, #Lagos, #Mumbai.

Well over $20B in taxpayer, paid for assets being thrown away for a savings that's literally pennies on those dollars. I'm all for shrinking waste and increasing efficiencies in our government, but this is neither. science.org/content/articl…

Moon landing in 6 days! RESILIENCE is orbiting the Moon every 2 hrs, to land on Mare Frigoris (Sea of Cold). Rover TENACIOUS to explore & collect samples. Soft landing to everyone at ispace! en.wikipedia.org/wiki/Hakuto-R_…

☄️ Excited to share our new paper in JGR: Planets JGR-Planets: "Inferring Fireball Velocity Profiles and Characteristic Parameters of Meteoroids From Incomplete Data Sets" by myself and Maria Gritsevich ▶️ doi.org/10.1029/2024JE… #PlanetaryScience #Meteoroids #Fireballs

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…

ESA's astronomers are actively tracking 3I/ATLAS, which is now the third confirmed interstellar comet to pass through our Solar System! More info at: esa.int/Space_Safety/P…

A view of lightning that's nothing like what we see on the ground: crew observations and instruments on the International Space Station can help us better understand the behaviors of storms.

Great to see research by Mount Allison's Vett Lloyd featured on the Globe today! theglobeandmail.com/canada/article…

I realize did not quite achieve their goal, but congratulations to all involved in the launch. Great to see Canada active in space launch, and by a university student group particularly impressive. theglobeandmail.com/business/artic…

That's an interstellar comet, imaged by a satellite orbiting Mars. You live in the future! esa.int/Science_Explor… European Space Agency

I have not been on this account much. I came back to tell you that Harvey (no not the one many followers know!) is now worth $11 billion. I am told more than more than Spirit Airlines, Nordstrom, and Macy's combined x.com/biconnections/…
