BREAKING: Inside Impulse Space with Tom Mueller (@lrocket) (SpaceX's 1st Employee)
FULL TOUR
The famous engineer behind the Merlin engine, now Founder, CEO & CTO of Impulse Space (@GoToImpulse)
ICYMI: Merlin still powers Falcon 9 today, the most reliable rocket engine ever flown & the highest thrust-to-weight ever developed. It's the workhorse behind nearly every SpaceX mission: Starlink launches, Dragon crew & cargo flights to the ISS, & booster landings
Tom walks us through the factory floor, from the avionics clean room to a live rocket engine firing in the vacuum chamber
Impulse is building the in-space mobility layer: the vehicles & engines that move spacecraft after launch, from LEO to GEO, the Moon, infinity & beyond
We cover:
→ Mira: precision maneuvering spacecraft & its saiph thrusters (8 thrusters, ~50 lbs thrust, 5-yr orbit life)
→ Helios: long haul same-day delivery vehicle (12 tons of LOX/methane, LEO to GEO)
→ Deneb Engine: 15,000 lbs thrust engine that powers Helios, ox-rich staged combustion, carbon skirt running over 3,000°F
→ Why 3D printing is "almost a cheat code" for rocket engines
→ In-house composite tanks, Novaloy, & copper liners machined from 700 lbs down to 25
→ 3 spacecraft in orbit + a 1,200-meter rendezvous
→ Starlink, iterating Merlin & Raptor, & working with @elonmusk
→ Nuclear propulsion, the Moon, & why compute needs to move to space

Stick Your Tongue Out: The Silent Release
Dr. Elena Vasquez had seen thousands of patients at Mount Sinai, but Marcus was different.
A 42 year old software engineer, he arrived with shoulders permanently hunched, eyes shadowed by perpetual exhaustion, and cortisol levels deep in the clinical anxiety range.
Therapy and medication adjustments brought little change. His body was locked in a silent civil war.
One afternoon, after reviewing his latest scans, Elena made an unusual request.
“Stick out your tongue,” she said. “As far as you can. Hold it for forty seconds.”
Marcus blinked. “Is this a test?”
“Consider it an experiment,” she replied, her voice calm but certain.
He complied, feeling ridiculous at first. The muscle strained, unfamiliar and awkward. His jaw trembled. His neck, usually rigid from years at a desk, began to burn with a deep, releasing ache. Forty seconds felt eternal.
“Do this twice a day,” Elena instructed. “Morning and evening. That’s all.”
Marcus left skeptical. But he tried it anyway.
The first few days brought nothing but mild soreness. Then, on day six, he noticed something strange during his morning routine: his shoulders dropped an inch without effort. The constant low hum of background tension, the one he had lived with so long he forgot it existed, had quieted.
By day twelve, his wife commented that he seemed lighter. Less reactive to traffic, to deadlines, to the thousand small irritations that once wound him tight. When he returned for bloodwork two weeks later, the numbers confirmed what he already felt: his cortisol had plummeted from dangerously high to the middle of the normal range. No medication changes. No new therapy. Just the daily tongue extension.
Elena was not surprised. She had studied the hidden architecture of chronic stress for years.
The neck carries an enormous burden, often 60 to 80 percent of the body’s accumulated tension. That tension does not stay polite. It compresses the vagus nerve, the body’s master regulator of calm.
It restricts the gentle flow of cerebrospinal fluid that bathes the brain. It keeps the entire nervous system whispering danger even when the world is quiet.
The tongue, surprisingly, is the key. It connects directly to the hyoid bone, that floating anchor for the deep muscles of the throat and neck.
When you extend the tongue fully, you create a gentle but powerful traction through the fascial chains, those webs of connective tissue running from jaw to chest. Like loosening a knot that has been pulling on everything downstream.
One simple movement. Forty seconds. Twice a day.
Marcus became her quiet advocate. He taught the technique to his overworked colleagues, his stressed sister, even his skeptical father. Some felt nothing. Others, like him, experienced a profound unwinding.
Years later, when people asked Elena about her most elegant intervention, she would smile and say:
“The brain is rarely the villain. More often, it is simply what is wrapped around it, layer after layer of unnoticed armor. Sometimes the most powerful medicine is learning how to take it off.”
And in those moments, she would remember Marcus: the man who learned to release what he did not even know he was holding.

We got married on a Saturday in Canada. On Monday, we were emigrating to the United States. My new wife and I said goodbye to the movers, flew to the border, and I got pulled into the big glass room for "extra questioning".
From her vantage point, she could see the immigration officer yelling, turning red, and waving his arms. She thought we were being denied entry... my Microsoft dreams crashing down right there.
What she couldn’t hear was that he had already approved my work visa. He was furious because their copy of Microsoft Word was printing a blank page at the end of every document, and it was wasting paper, and he wanted it fixed.
I helped adjust the margins. And so, after fixing the borders at the border, they released us to our new life in America.
There is a graveyard in American tech right now and nobody is walking through it. Companies down 70, 80, 90% from the highs. Still profitable. Still growing. Still the leader in their category. Just unloved. The Trade Desk at 9x earnings. PayPal at 12x with $6 billion in free cash flow. Adobe at 17x and people are talking about it like it’s Kodak. Etsy at 8x EBITDA running a marketplace that two billion people have heard of. Roku trading below its own balance sheet liquidation value if you squint. Match Group, Zoom, Pinterest — each of these would have been a hedge fund’s top pick at this multiple in 2017. Now they’re orphans. Everyone is buying the Mag 7 because the Mag 7 is the trade. The Mag 7 IS already the trade. The trade is over. The next trade is in the rubble pile. You don’t get rich buying what worked. You get rich buying what stopped working for reasons that turn out to be temporary. Every name on that list was a market darling 36 months ago. The fundamentals didn’t fall 80%. The narrative did. Narratives come back. Earnings compound. I’m not buying NVDA at 45x. I’m buying the names CNBC won’t say out loud anymore
TIL the world’s largest thermal baths are 2 MILLION square feet (35 football fields!)
Discovered in 1983 when Texaco was digging and struck hot mineral water; now has 40 different pools and 35 saunas
It’s just 12 mins from MUC, great for a long layover.
I’m going tomorrow
💥NEW: Rahm Emanuel *NUKES* Dem Party💥
KATIE COURIC: “Why do you think people feel so negatively about the Democratic party?”
EMANUEL: “Because we EARNED their disrespect — the hard way!”
“We did things that were really RIDICULOUS! We let a border get out of control, we talked about defunding the police, we called them Latinx — and NOBODY else in that group EVER identified themselves that way.”
Did you know that federal employees can add anyone to their health insurance plan with NO accountability?
I requested a report on this and found out around ONE BILLION DOLLARS per YEAR went towards fraudulent coverage. Government employees NEVER had to verify if the person they were adding was family. I introduced the FEHB Protection Act, which became law, to fix this problem and stop the fraud.
Americans deserve a system with accountability, not a free-for-all funded by federal tax dollars.
Build a simple agent that scans your engineers’ Cursor, Codex, and Claude Code logs every day.
It quietly checks which models they’re actually using for which tasks, then posts suggestions + roasts into a public Slack channel.
Believe me 99% of engineers have no idea about model configuration differences and they are using absurd models like Opus 4.8 1M xHigh Fast for everything.
You can easily cut your AI spending by 50-60% with zero nagging.
The Undercroft beneath the Lincoln Memorial and it’s a fascinating story that’s suddenly in the news because the public can finally see it.
The Lincoln Memorial sits on what used to be swampy, marshy land (the Potomac Flats) that was reclaimed from the river through dredging and filling. When construction started in 1914, engineers knew the soft soil couldn’t support the massive marble structure and the huge statue of Lincoln without it sinking.
Their solution was to excavate down roughly 40–50 feet and install about 120–122 massive concrete pillars (sometimes called piers or piles). These were driven all the way down to solid bedrock. The pillars support the entire weight of the memorial above. The huge open space they created underneath, a cavernous, roughly 50,000-square-foot structural chamber (nearly twice the size of the memorial itself) is called the Undercroft.
For over 100 years this space stayed hidden from the public. It was basically a giant concrete forest of towering pillars holding everything up, with some original construction graffiti still visible on them and even stalactites from water seeping through over time.
The National Park Service has turned part of it (about 15,000 square feet) into a new museum and exhibit space. You can now walk in and see the actual massive concrete supports that were put in because of the swampy ground, along with interactive exhibits about the engineering challenges, the memorial’s construction, and its powerful role in American history (including civil rights moments like Marian Anderson’s concert and MLK’s “I Have a Dream” speech).
It officially opens to the public on June 25, 2026, with timed-entry tickets required (free admission, small service fee for advance reservations). It’s already getting a lot of attention in the media as one of Washington’s “best-kept secrets” finally revealed.
UPDATE: @NASA can confirm a fireball over New England at 2:06 p.m. EDT on Saturday, May 30, 2026. The meteor was about 5 feet (1.6 meters) in diameter with a mass of 5.6 metric tons and entered Earth’s atmosphere at roughly 42,000 mph.
The meteor traveled through the atmosphere from northwest to southeast for 26 miles before breaking up at an altitude of 31 miles and producing a meteorite fall into Cape Cod Bay.
Based on the latest data, the energy released at breakup is estimated to be equivalent to about 230 tons of TNT, which accounts for the sonic boom.

🇺🇸 The U.S. Army just ran a massive hackathon called Operation Jailbreak.
Engineers from Boeing, Palantir, Anduril and others flew to Fort Carson to solve something that has plagued the army for years: American weapons can't talk to each other.
In days, five companies built a machine-gun robot networked into drones and counter-drones, controlled from a single screen.
The Army Secretary wants solutions deployed to CENTCOM within 30 days to counter Iranian drones.
It only took a war, a hackathon, and probably tons of energy drinks to get there.

STUDY FINDS 96% REMISSION RATE OF ALPHA-GAL SYNDROME WITH AURICULAR ACUPUNCTURE
With nearly 500,000 Americans now affected by tick-induced meat allergy, a peer-reviewed study reports almost unbelievable results using a little-known form of ear acupuncture.
Researchers evaluated 137 patients with alpha-gal syndrome treated with Soliman Auricular Allergy Treatment (SAAT).
Among patients with follow-up data, 96% reported remission of symptoms after treatment.
Many who previously could not tolerate beef, pork, dairy, or other mammalian foods were reportedly able to reintroduce them without allergic reactions.
The procedure is unusual. Patients do not ingest or get injected with alpha-gal.
Instead, they simply touch a vial containing the allergen while clinicians identify a reactive point on the ear using electrical detection.
A tiny acupuncture needle is then placed in a specific auricular zone and left in place for about three weeks.
Even among patients with a prior history of anaphylaxis, 93.1% reported no subsequent symptoms after accidental—or in some cases intentional—exposure following treatment.
No adverse reactions to the acupuncture procedure itself were reported.
This was a retrospective case series, not a randomized controlled trial.
But with AGS cases exploding and no accepted treatment beyond avoidance, a reported 96% remission rate is difficult to ignore.
