Hello everyone, Last month, I launched a fundraiser to provide engineering equipment for Ukraine, but due to low donations, I had to pause and reassess. Today, I’m relaunching the fundraiser and want to share an example of the impact of the machines we provide. Please share and…
The murder of Ukrainian politician Andriy Parubiy is not the only one in which Russia is or may be implicated. This is how Russia exacts revenge for successful Ukrainian special operations, intimidates, and pits people with different views against one another. #UkraineWar
Sorry, what was given on Sunday was rehash. No new details at all that I could see.

This is a great, short sci-fi film (~15 min long). It gave me chill bumps at one point.

Got a good look at the new V3 Raptor engine at Starbase. The new design looks very clean! @NASASpaceflight
I'd bet this person has never bought a single sat image, let alone spent hundreds of hours painstakingly counting AND identifying vehicles like @HighMarsed and @Jonpy99 have. It's incredibly laborious work. So you can imagine the frustration when someone steals it without credit

🚨NEW: Senator John Cornyn (R-TX) just voted to block the release of the Epstein files in the Senate Judiciary Committee. RETWEET to let Texas know that Cornyn is covering for Trump!
After spending the last few months capturing it, I'm thrilled to share with you my newest artwork, my deepest look at the milky way yet. A 140 hour exposure, revealing the chaos happening in our skies. I call it "Above the Rift". Here's a short thread about what you're seeing.
How do we take group photos in space? We cannot ask a passerby for help, so we set up a camera to take a photo every 5 seconds, get in position, then stop to smile at the camera. Looks a little chaotic, but it works!
Tired of narratives that paint Russians as victims. They’re not. Russia chose war. Ukrainians didn’t. Stop rewriting history to comfort the aggressor.

NEW and BREAKING: The day after former FBI director James Comey posted a photo of seashells arranged in "86 47," the Secret Service had him physically surveilled and tracked his location through his phone. w/ @esullivannyt nytimes.com/2025/07/09/us/…
One of the most "amusing" things on X is Russian troll farms flood comments, trying to convince me how Russia is “saving” Ukrainians : As if I forgot that when Russian troops were closing in on my hometown, my parents had to hide my old parade uniform because days earlier,…
Hello everyone, I am starting a new fundraiser for more engineering equipment (donation link at the end 🔗) While much of the fundraisers focus on delivering drones to Ukraine, I’m working on something just as critical: protecting our forces from enemy drones. To survive on the…
We are spending 2.9% of GDP on defense, the lowest since 1940 before WW2. It is inadequate for the security of our nation. We will go a long way in fixing this with the Reconciliation Bill. airandspaceforces.com/senate-reconci…
You've got my support! Thanks for running @AstroTerry. I'm a conservative voter, but the MAGAtes representing Texas in the US Senate need to be kicked out.

You all under stand that this is a Concentration Camp, right? RIGHT?!
It turns out a key figure behind “Palestine Action” is James "Fergie" Chambers, a wealthy American communist and outspoken supporter of Russia’s invasion of Ukraine. Chambers has spent time in occupied Ukraine and no doubt had extensive contacts with Russian intelligence.
