Yang et al. 2025, "Spectroscopic Characterization of Interstellar Object #3I/ATLAS: Water Ice in the Coma" - arxiv.org/abs/2507.14916
#3I is putting out water ice along with organic and silicate dust.
As expected for a comet.

Spectroscopic Characterization of Interstellar Object 3I/ATLAS: Water Ice in the Coma
We present optical and near-infrared spectroscopy of the interstellar object 3I/ATLAS, obtained with Gemini-S/GMOS and NASA IRTF/SpeX on 2025 July 5 and July 14. The optical spectrum shows a red slope...

Ukraine has continously asked for 11-20 Patriot batteries. Here's what kind of coverage you can get with 11. Ukraine has 6~ batteries already, the remaining 5 would cost something like (barring missiles) $1.7-2B. A Patriot batteries goes for $300-400M (export/local costs are the same).

It is imperative Russia be defeated swiftly and overwhelmingly so that our resources can be prioritized to China. We cannot afford a two front Cold War in both Europe and Asia.

UPDATE on our new interstellar friend #A11pl3Z:
Citizen scientist Sam Deen has found earlier observations of from June 25-28, from the ATLAS telescope!
Now with 6 days' worth of data, the eccentricity of A11pl3Z's trajectory is narrowed down to e=10.4 ± 1.1!
... that's undoubtedly interstellar.

Today we are going learn about Light Exo-Atmospheric Projectile's first flight test. So what is LEAP? LEAP was a program aimed at developing extremely lightweight and small KKVs. The program first spawned from an SDI effort develop a light kill vehicle for ground or space based hyper-velocity guns.

$4.2B for naval infrastructure stuff (construction, workforce, stuff of that sort)
1 Extra VA Boat in FY27
2 Extra DDG-51s
$1.8B for LSM not sure how many this covers.
