The Golden Girls, but with today’s hair and styling. From big 80s perms to sleek, fresh looks, Blanche is out here serving main character energy, Rose looks like your cool aunt who does Pilates, and Sophia and Dorothy still delivering one liners with the best of them. Do you think the comedy would still hit the same today?

The view from inside Integrity as recovery forces pop open the hatch…watching the helicopter pass over their shoulders and hearing all the joy, it was as good as it gets.

Patrick Winston taught engineering at MIT for 50 years. This is his last lecture. He died 5 months after recording it. It was his final gift to the world. 1000s of the greatest minds passed through his classroom and went on to engineer the world. He has some wisdom…

SLS vs. Saturn V, a real time comparison. Saw a comparison yesterday using my video on the left at 50% speed. Here's a proper comparison with both rockets launching at their real speeds. You'll notice SLS is significantly faster off the pad because of the dual massive SRBs!

It's not just a phase 🌕 Artemis II astronauts captured these views of the Moon as the Orion spacecraft flew around the far side of the Moon on April 6, 2026.

Safety first! The Artemis II astronauts can be seen in their eclipse glasses, worn to protect their eyes when they experienced a solar eclipse on April 6. The Sun, the Moon, and the Orion spacecraft aligned — and Moon joy was had!

In 2013, my great friend & director Mark Craig asked Gene Cernan - the last human to walk on the lunar surface - what words he had for the next astronauts to go to the Moon. And here they are, in tribute to @NASA's Artemis II crew & those that will follow. Please watch with volume up. Credit: Mark Stewart Productions/Haviland Digital/Stopwatch Productions

I'm honestly SHOCKED at how the general public has NO IDEA Artemis II is taking humans out to the moon and will be the furthest humans have ever flown. Every non-space nerd I've talked to has no idea. WE GOTTA GET PEOPLE STOKED!!!! THESE FOUR HUMANS ARE FLYING TO THE MOON!!!

George Lucas traded $350,000 in directing salary for something Fox executives thought was worthless: the right to sell Star Wars toys. It was 1976. Over 40 studios had already passed on his script, including Disney. Fox only greenlit the project because they wanted Lucas for other films. Nobody at the studio expected to make money on a space opera with no stars, so when Lucas offered to cut his directing fee from $500,000 to $150,000 in exchange for merchandising and sequel rights, Fox said yes on the spot. Movie merchandise was a dead business. Fox had lost money on Doctor Dolittle lunchboxes a decade earlier. They thought they were getting the better deal. Lucas couldn’t even find a toy company that wanted in. Kenner, a division of cereal company General Foods, finally bought the licensing for a flat $100,000. Then Star Wars opened. Between 1977 and 1978, Kenner sold $100 million worth of toys off that $100,000 investment. They couldn’t make enough for Christmas ’77, so they sold empty boxes with IOUs inside, promising to mail the action figures later. Parents paid real money for cardboard and a promise. Nobody around the production saw any of this coming. Alec Guinness, who played Obi-Wan, privately called the script “fairy-tale rubbish.” But he was shrewd enough to negotiate 2.25% of royalties instead of a flat fee. About 20 minutes of total screen time earned his estate somewhere between $50 million and $100 million. Lucas himself was so convinced the film would flop that he offered Spielberg a bet while visiting the Close Encounters set: swap 2.5% of each other’s profits. Spielberg took it. That handshake has paid him around $40 million. And then the money started compounding. Lucas poured his Star Wars profits into ILM, the effects house he’d built for the film. When its computer graphics division got too expensive to maintain, he sold it to Steve Jobs in 1986 for $10 million. Jobs renamed it Pixar. Disney bought Pixar twenty years later for $7.4 billion. Then in 2012, Disney came back for the rest, buying Lucasfilm itself for $4.05 billion. Total franchise revenue today sits around $46.7 billion, over $20 billion from merchandise alone. The filmmaker 40 studios passed on is now worth $5.3 billion according to Forbes. Fifty years ago today, cameras rolled on a desert in Tunisia. The $350,000 pay cut that made it all possible might be the best trade in business history.

In 1994, during a power outage, the only time the Milky Way was visible in the city of Los Angeles, many people were scared by the sight and called 911.
