This photo of the moon taken by the Artemis crew was done at a ISO setting of 51,200, the sun is behind the earth, what you are seeing is the disc of the earth experiencing night. Fascinating, notice the stars in the background and the northern lights at the fringe of the earth.

We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.

@KemeshaSwaby In a few years take him to Kennedy Space Center and show him the Saturn V rocket to further deepen his interest. Built by engineers with slide rules and log tables

My son son was so clued into the Artemis II launch yesterday, and his eyes definitely lit up a little more seeing Glover. He was also pretty excited that there was so much coverage of the control room, and we talked about how all the roles are important.

Victor Glover (pilot of Artemis II) was already a spacecraft pilot for SpaceX Crew-1. He is a naval captain who has had his naval aviator wings for 25 years. He has three (3) masters degrees, including in flight test engineering and systems engineering. He's been a test pilot since 2007. He has thousands of flight hours.

In 1969 NASA used telecine rescan to upscale Eagle video transmission to NTSC In 2026 they are using optical links. Both RF/optical links are subject to Shannon and Friis constraints though however the high frequency of optical increases bandwidth news.mit.edu/2026/lincoln-l…

On their first apogee, nearly 44,000 miles from Earth, the Artemis II crew is getting a look at home unseen in 53 years. Here's Christina Koch describing her view of sunset in India a few minutes ago.

@travismacmillan NK attained nukes because Seoul was within range of 10,000 NK artillery batteries , so any attempt to stop them would have resulted in the destruction of Seoul. Iran was seeking a similar method hold the Gulf at ransom with 20,000 missiles and then develop a nuke.

If USA had a Trump as president instead of a Clinton, North Korea wouldn’t have been able to obtain nuclear weapons and threaten the world for any attempt to free 12+ million humans starving to death in the worlds largest totalitarian cult. Thank God Trump prevented WW3. 🙏

@williamdw40 That’s reasonable but I still don’t intuitively believe it was live that many decades ago, have to clarify that my position is that it happened but was not shown live

Nah after watching this live launch with 2026 camera technology look so grainy, the original moon landing had to be pre-recorded 😂 (They still went tho)

@KyleAnthonie I can only point persons to authentic scientific data how it is received is beyond my control, but for what it’s worth NASA researched this very issue years in advance of the Apollo missions. nms.ac.uk/discover-catal…

@KyleAnthonie There is a lot of misinformation floating about image quality from 1969 versus now because a lot of people don’t have the scientific literacy to understand how a data bandwith budget at 250,000 miles link has to prioritize life safety and vehicle telemetry vs video.

@williamdw40 Oh yeah they for sure went but i’m not certain the broadcast was live, that seems too unbelievable seeing how hard it is to get sharp images live even today

@KyleAnthonie What was done instead Is they used the device called telecine and literally had a live low res feed going to NASA HQ which was then re-scanned at a higher resolution to be broadcast to the general public so they had a camera looking at a TV screen at NASA headquarters

@travismacmillan I don’t think people realize how much guts and bravery it takes to do this. You’re in an enclosed space for 10 days hundreds of thousands of miles from any sort of help. It’s a test of mental health.

@williamdw40 Trust me… as a man who’s claustrophobic and more and more aware of how insane flying in a commercial jet in theory is,.. I have nothing but pure praise for anyone with the fortitude to get into a controlled explosion into a void and hoping newtons laws still work. 😂

If you're under 53 years old, you have never once been alive while a human was farther than 250 miles from Earth. Tonight, four astronauts are heading 252,000 miles out. That's a thousand times farther than any person has gone in your lifetime. The 250-mile ceiling is where the International Space Station floats. Every astronaut since December 1972 has been stuck in that zone. Spacewalks, science experiments, cool photos from orbit, sure. But nobody left the neighborhood. The last crew to go farther was Apollo 17. December 1972. Nixon was president. The internet didn't exist. Cell phones were 11 years away. The youngest member of that crew is now 90 years old. The farthest any human has ever been from Earth is 248,655 miles. The Apollo 13 crew set that number in 1970, and they didn't mean to. Their oxygen tank blew up, and the emergency route home took them farther out than anyone before or since. Tonight's crew will break that record on purpose. And the crew itself. Victor Glover becomes the first Black astronaut to leave Earth's neighborhood. Christina Koch becomes the first woman. Jeremy Hansen, a Canadian fighter pilot, becomes the first non-American to do so. When they come home, they'll slam into the atmosphere at 25,000 mph, faster than any human has ever traveled. The Moon's south pole has ice. Water ice, sitting in craters so deep that sunlight hasn't hit them in billions of years. A 2024 NASA study found way more of it than anyone expected. You can split water into hydrogen and oxygen, which gives you rocket fuel, breathable air, and drinking water, all made on the Moon instead of hauled up from Earth. George Sowers at Colorado School of Mines calculated that Moon-made fuel could shave $12 billion off a single trip to Mars. The Moon is a gas station on the road to Mars. NASA Administrator Jared Isaacman announced last week a $20 billion plan to build a permanent base at the South Pole over the next seven years, with landings every six months. China is developing its own lunar lander and spacesuit, aiming for a crewed landing by 2030. The Artemis program has burned through $93 billion so far, and the first actual surface landing is penciled in for 2028. There's a real question of who gets there first this time around. Harrison Schmitt walked on the Moon in December 1972 as part of Apollo 17. He's 90. Asked about it this week, he sounded pretty relaxed. "Mars is attainable," he said. "We're humans. That's what we've always done."
