16th Infantry Regiment of the 1st Infantry Division moving towards Omaha Beach, taken by Robert Capa.
One of the Magnificent Eleven photos we have of his. He took over 100 that morning, but most were lost in a processing accident.
Reminder for all young parents:
You only get:

This time is precious. Don’t rush it.
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

Today we're announcing unprecedented federal & state cooperation in Ohio in the fight against fraud, including:
✅Partnerships & a data sharing agreement to enhance the detection & prosecution of fraud
✅Federal & state charges against 9 defendants for their alleged participation in $42+ million in fraud
✅Orders of detention this week for three defendants, with two additional defendants pending extradition in connection with an additional $15 million in fraud
✅The creation of the FBI’s Most Wanted Fraudsters list
"By holding these fraudsters accountable and partnering with the FBI on a robust Most Wanted fraudster list, we are pursuing fraud more aggressively than ever. No fraud scheme is beyond our reach.” - Acting Attorney General @DAGToddBlanche
Roscosmos has paused Friday’s structural repair efforts inside the Zvezda service module transfer tunnel, known as PrK, as more measurements and data is assessed. Given this development, NASA has instructed the crew members inside the Dragon spacecraft to end the safe haven procedures and return to planned operations aboard the International Space Station. We look forward to working with Roscosmos on a collaborative approach to address the leaks.
The Zvezda service module transfer tunnel, known as PrK, has suffered from cracks and leaks for some time, and has been mitigated by Roscosmos as much as possible to date. The cracks have always been a concern that NASA watches very closely. NASA and Roscosmos have been working to determine the root cause of the cracks, and Roscosmos manages the issue through operational mitigation measures and periodic partial-repair efforts. Following new leaks, Roscosmos has elected to proceed with a more extensive repair operation on Friday, June 5. Out of an abundance of caution, NASA has directed all four of the agency's SpaceX Crew-12 members and NASA astronaut Chris Williams to assume an elevated safety posture in the Dragon spacecraft while the repair is underway. We continue to work with our Russian counterparts, along with the rest of the international community that supports the space station, to arrive at a more permanent resolution.
The Challenger disaster never happens.
NASA doesn’t just lose seven astronauts that day. It loses momentum, trust, and maybe an entire generation’s belief in how far we could go.
One of America’s biggest “what ifs.”
It'd be interesting to find out what the "more extensive" repair operation involves, to the point that the Crew-12 astronauts need to be (I assume) "inside" Dragon and ready to undock in the event those repairs...well, it wouldn't be good for anyone, not least the Cosmonauts conducting the repairs.
#MeteorSighting: Eyewitnesses in Ohio and Michigan reported a bright meteor on Monday, June 1, at 10:41p.m. EDT. The data puts first detection of the fireball above the Ohio area near Lima. The meteor moved north-northwest at approximately 49,900 mph before disintegrating above the area just west of Lansing, Michigan.
