On this day in 1969, Apollo 11 landed on the Moon. Commander Neil Armstrong’s words, “That’s one small step for [a] man, one giant leap for mankind,” remain legendary to this day. In Japan too, countless people were glued to their television sets to witness this historic moment. Despite the live broadcast starting early in the morning, NHK recorded a staggering 68.3% viewership rating. The longing for space crossed the ocean, delivering true courage and hope to living rooms across Japan.

Grok Bot summary: IAC 2026 presentation by SpaceXAI President Michael Nicolls. 🎯 The main message - SpaceX was founded in 2002 to make life multi-planetary and "extend the light of consciousness to the stars." - He said the biggest risk as constellations grow is not debris. It's satellite operators not sharing data with each other. 🌍 How Starlink grew - Starlink began in 2019 with 60 V0.9 satellites. User service started in late 2020 as the "Better Than Nothing Beta." - V1.5 added space lasers, which let the satellites link into a mesh. That's when Starlink really took off, reaching oceans, Antarctica and airplanes. - V2 (2023) has 4x the capacity of V1. Falcon launches V2 satellites 2–3 times a week, and each launch adds about 3 terabits of capacity. - V3 launched on Starship about a week before the talk. Each V3 satellite has another 10x capacity, and each Starship launch carries 20–30x what a Falcon launch does. - Starlink now has over 11,000 satellites, about 60% of all active satellites in low Earth orbit. - It serves more than 13M customers in about 170 markets, plus ships and planes. - The laser mesh means Starlink doesn't depend on local ground infrastructure. During last year's fires and power outages in Spain, it kept tens of thousands of customers and emergency responders online. 🚀 The life of a Starlink satellite - **Before launch:** SpaceX checks that deploying the satellites won't bring them close to anything else, and shares where they'll be. - **Deploy:** satellites are released below 300 km, where almost no other operators fly. - **Orbit raising:** each climb path is checked against other satellites and crewed space stations, and SpaceX publishes the satellites' positions every hour on the way up. - **Lower orbits for safety:** the original plan was about 1,000 km. Now every satellite flies below 500 km, and V3 will fly at about 350–360 km. At these heights a dead satellite falls back to Earth within months instead of staying up for centuries. 🛡️ How they avoid collisions - Each satellite makes small station-keeping moves about once a day and a collision-avoidance move about every 10 days. - Across the fleet, that's about 1,000 avoidance moves a day. - Starlink's threshold for moving is nearly 100x more cautious than the industry standard, so the whole fleet's collision risk is about the same as a much smaller constellation's. - "Ducking" moves turn the satellite so it presents a smaller target during a close pass, cutting the collision risk about 10x more. - Automated software makes these decisions, which is why Starlink tries to stay in contact with every satellite at all times. 📡 Always connected - Starship's live launch video was streamed over Starlink. - The new V3 satellites connected to the network within 2 minutes of release, because Starlink terminals are built into the satellites. Their lasers link into the mesh within tens of minutes. - The goal is to make contact right away and never lose it. 🌬️ Space weather - During a 2024 solar storm, air density in orbit jumped 5x in a few hours, which throws off predictions of where satellites will be. - Starlink is "probably one of the best sensors" for this. It measures density in real time and automatically corrects its position forecasts. 🔭 Working with astronomers - **Optical:** SpaceX tried Vantablack paint and sun visors. What finally worked was a mirror-like film that reflects sunlight away from the ground, combined with careful steering. A V2 satellite now looks about as bright as a sheet of paper. This was done with groups like the Vera Rubin Observatory. - **Radio:** working with observatories like the US National Radio Astronomy Observatory (NRAO), Starlink steers its beams and frequencies around where the telescopes are pointing. As a result, the telescopes can now observe more often. ♻️ End of life - SpaceX uses statistics to predict when parts will fail and deorbits satellites early. Many of those satellites would have kept working. - Retired satellites are steered down within weeks, not left to drift for the 5 or 25 years regulations allow. - They're built to burn up completely, and reentry is aimed over the ocean. - Of about 10,000 satellites launched by early 2026, only a few dead ones remain in orbit. The goal is zero. - "Reliability and rate go together." ⚠️ The biggest danger: other operators - Tracked debris is like obstacles on a road: if you can measure it, you can avoid it. - What you can't avoid is a satellite that maneuvers without telling anyone. Starlink has had passes as close as tens of meters this way. - Starlink has maneuvered around satellites from about 650 operators in recent months, but shares position data with only about half of them. "That number is too low." - SpaceX shares data with China's space station and some Chinese operators. Many operators don't share at all, including some in the US, Europe and Japan. ⭐ Stargaze: Starlink's own space tracking - Over 30,000 star trackers on Starlink satellites spot passing objects as streaks against the stars. - Stargaze now tracks over 17,000 objects, including about 90% of the maneuvering satellites that cross Starlink's orbits. - In one example, an untracked satellite's predicted 9 km miss shrank to about 60 m after it maneuvered toward Starlink. Stargaze caught the move and the Starlink satellite dodged in time. - He said it's still no substitute for operators sharing their plans in advance. 🤝 The ask: share your data - SpaceX runs its own space safety data platform, and over 100 operators have signed up. - Operators can upload their satellite positions and check them against Starlink and against Stargaze tracking. - His message to every operator was to join the platform and share their positions. 🧠 StarMind: AI compute in space - StarMind is SpaceX's planned AI satellite constellation, starting launches and scaling next year. - The goal is to move AI compute off Earth. He expects StarMind to drive demand for Starship launches the way Starlink did for Falcon. - On the ground, SpaceX is building over 2 GW of compute in Memphis. He said AI demand will be nearly limitless, and Earth's resources make that hard to keep scaling there. - In space, the satellites run on solar power and shed heat through large radiators. - Each satellite is simpler than a Starlink: basically a computer with big solar panels and radiators. - Each one has about 250 kW, roughly one NVL72 rack of compute. - They'd fly in tight clusters of about 10 satellites linked by about 10 terabits of bandwidth, then connect to Starlink. - SpaceX has filed for up to **1 million satellites**, in low-inclination and sun-synchronous orbits. Building them could mean thousands of satellites a week. - New challenges include much higher reliability and redundancy, flying in close formation, and micrometeoroids. Dead satellites might be sent away from Earth instead of burning up in the atmosphere. 🌙 Beyond Earth - Starlink is developing very high-bandwidth lasers to connect the Moon, then Mars, building an "interplanetary mesh." - All of that depends on getting safety right in low Earth orbit first. 💡 Key takeaways - Starlink is the world's biggest constellation, and it's moving lower to be safer. - It makes about 1,000 collision-avoidance moves a day, with nearly 100x more caution than the industry standard. - The biggest risk is operators who don't share where their satellites are going. - StarMind could scale to 1 million AI satellites, with launches starting next year. - "Coordination is a key element for realizing all of our ambitions."

WATCH IT TO BELIEVE IT 🌕 Italian photographer Valerio Minato has spent six years chasing an almost impossible composition: capturing Turin's Basilica of Superga, the jagged peak of Monviso, and the setting Moon in exact alignment 🤯 To make the scene truly magical, he needed a slender crescent displaying the rare "Da Vinci Glow"—a subtle, ghostly illumination across the Moon’s dark side caused by sunlight reflecting off Earth's oceans and clouds back into space. The vision began in 2017. Setting up on a hill in Castagneto Po, Minato calculated a vantage point roughly 25 kilometers from the basilica and over 100 kilometers from Monviso. Using a 400mm telephoto lens with an extender, his goal was extreme optical compression—flattening tens of kilometers of terrestrial terrain and 384,000 kilometers of cosmos into a single plane. The celestial mechanics were unforgiving. The Moon’s path only traced that precise azimuth in that exact phase for five or six days each year. From 2017 to 2022, every single attempt was ruined by cloud banks, winter fog, or thermal haze. At 6:52 PM on December 15, 2023, the skies finally cleared and the conditions converged. Because of Earth’s rotation, the alignment would last for a fleeting window of just 30 to 45 seconds. Shooting in the freezing dusk, Minato pressed the shutter the exact moment the lunar crescent embraced the cathedral's dome and alpine silhouette in a razor-sharp line. The resulting symmetry looked so surreal that social media quickly erupted with accusations of generative AI and Photoshop manipulation. To silence the skeptics, Minato released unedited behind-the-scenes video footage showing the Moon physically tracking behind the basilica’s cross in real time. Just ten days later, NASA erased any lingering doubt by selecting the shot as its Astronomy Picture of the Day on Christmas Day, 2023. A cosmic spectacle that lasted barely half a minute, brought to life by six years of persistence, telephoto optics, and orbital mathematics.

On January 15, 2025, Falcon 9 successfully deployed Firefly Aerospace’s Blue Ghost Mission 1 and ispace’s RESILIENCE lunar landers on a trajectory to the Moon from pad 39A in Florida. For most of our missions, we plan a controlled deorbit of the Falcon second stage so it safely reenters over the ocean. For higher energy missions like those to a lunar transfer orbit, nearly all performance on the vehicle is devoted to successfully placing the payload in the intended orbit, and a controlled disposal maneuver is not always possible. We actively work to be as responsible as possible with hardware left in space to ensure space safety, including for more complex missions. In this case, over time, solar activity and gravity led the second stage toward the Moon. Impacts like this are rare, but they can happen with objects in these types of orbits, and we worked with NASA on the optimal disposal solution. Our focus remains on advancing reliable access to space while working toward even more sustainable operations with Starship in the future. As a fully reusable vehicle, Starship is designed to eliminate expendable upper stages entirely, reducing hardware left in orbit and enabling even more missions to the Moon, Mars, and beyond.

Light does not show us the Universe as it is now. It shows us the Universe as it was when that light began its journey. If a hypothetical observer were 4.5 billion light-years away and could somehow resolve Earth in sufficient detail, the light reaching them today would have left around the time our planet was forming. They would not see humans, dinosaurs, trees or even the earliest known life. Earth itself formed about 4.54 billion years ago from material surrounding the young Sun. Its early surface was dramatically different from today, shaped by intense impacts, volcanism and the gradual formation of its crust and oceans. The same principle works on smaller scales. We see the Moon about 1.3 seconds in the past, the Sun about 8 minutes and 20 seconds ago, and the Andromeda Galaxy as it appeared roughly 2.5 million years ago. So an alien civilization 100 million light-years away would receive Earth’s light from long before humans existed. One 2,000 light-years away would only now be receiving light that left Earth around the era of the Roman Empire. There is one major limitation: actually resolving Earth from billions of light-years away would require observational capabilities far beyond anything known today. The statement is therefore a thought experiment about light-travel time, not something a realistic telescope could currently accomplish.

SpaceX just officially posted the full recap of Starship Flight 14, and it's a huge milestone Starship reached orbit for the first time and delivered real payload to space Here's everything that happened, and why it matters: 1. The launch: Starship lifted off from Starbase, Texas on September 28 on its first ever attempt to reach orbit. The Super Heavy booster lit all 33 Raptor 3 engines. One engine shut down during the climb, but the booster still completed its job and pushed Starship toward space. 2. Stage separation: Starship lit its own 6 engines while still attached to the booster (hot-staging) and separated cleanly. 3. The booster tested its limits: Super Heavy flipped around and relit 31 of 33 engines to head back. SpaceX deliberately used up nearly all the remaining liquid oxygen in the booster's main tank during this burn. Why? To find out exactly how much margin the booster has before future missions where it flies back to the launch site. It then relit 11 of 13 engines for landing, throttled down to 5, then 3, and splashed down in the Gulf of America. 4. Starship handled an engine failure: One of Starship's 6 engines shut down early on the way up. The other 5 simply burned longer to make up the difference, and Starship still reached its planned path. That's the redundancy doing exactly what it was designed for. 5. First time in orbit: Engineers checked the ship, confirmed the engines needed for later burns were healthy, and gave the go. Starship relit one engine in space and pushed itself into orbit around Earth for the first time ever. 6. First real payload: Starship deployed all 26 Starlink V3 satellites. SpaceX made contact with every single one. They'll now run checkouts and raise their orbits before serving customers. 7. First deorbit burn: Because of the engine issue on the way up, the team played it safe and shortened the time in orbit. Starship relit one engine to slow itself down and drop out of orbit, the first time it has ever done that. This is a critical skill: a ship that can reach orbit must also be able to come back on command. 8. Splashdown: Starship came through reentry, relit all 3 of its landing engines, flipped upright, and splashed down on target in the Pacific Ocean. What Flight 14 proved: • Starship can reach orbit • Starship can deliver real satellites • Starship can survive engine failures and still finish the mission • Starship can relight in space and bring itself home from orbit This is the rocket that will launch the next generation of Starlink, and eventually carry humans to the Moon and Mars

Grok Bot summary: Starship Flight 14, the first orbital Starship flight. 🔥 Ascent - During the climb, one Raptor vacuum engine shut down early. - Starship made up for the lost thrust by burning its other five engines for longer than planned. - It still reached its planned suborbital path. That path is "passively safe," meaning the ship would come back down safely on its own if nothing else happened. ✅ Go for orbit - Once it was on that path, the flight control team checked the ship's systems. - The three sea-level Raptor engines needed for later burns were healthy, so the team gave a "go" for orbital operations. 🌍 First time in orbit - Starship relit one sea-level Raptor for an orbit insertion burn. - **It entered orbit around Earth for the first time ever.** 🛰️ 26 Starlink V3 satellites deployed - After a short coast, Starship released all 26 Starlink V3 satellites. - SpaceX soon made contact with every one of them through laser links, ground stations and Starlink user terminals. - Next, the satellites run on-orbit checks and raise their orbits, then start serving customers. - Because of the engine problem on the way up, the team cut the time in orbit short "out of an abundance of caution." - They brought Starship down in the northern Pacific Ocean. That was one of two landing zones agreed before launch, and it was cleared of ships and aircraft. 🔻 First-ever deorbit burn - Starship relit one sea-level Raptor to slow down and drop out of orbit. - It then made it through atmospheric reentry and descent to the planned splashdown point. 🌊 Landing burn and splashdown - For the final landing burn and flip maneuver, all three sea-level Raptors relit. - Starship **splashed down on target** in the Pacific Ocean. 📌 Starship firsts on this flight - First time reaching orbit - First real payload deployed from orbit (26 Starlink V3 satellites) - First deorbit burn - A controlled splashdown on target, despite losing an engine on the way up 💡 Why it matters Getting to orbit, releasing real satellites, and coming back down under control are key steps toward Starship's big goals: flying Starlink at scale, fully reusable rockets, and eventually the Moon and Mars. Flight 14 did all of that, even after losing an engine.

WE HAVE BARELY LEFT EARTH — AND THE NUMBERS ARE SHOCKING Humanity has sent people to the Moon, built machines that can see billions of light-years away, and created spacecraft that have been traveling through space for decades. The observable universe is about 93 billion light-years across. It contains an almost unimaginable number of galaxies, stars, planets, and worlds that we may never be able to reach. Yet the farthest any human being has ever traveled from Earth is only about 1.3 light-seconds. That record was set during the Apollo missions, when astronauts traveled to the Moon. Light can cross the greatest distance humans have ever traveled in roughly 1.3 seconds. But crossing the diameter of the observable universe would take light about 93 billion years. Voyager 1, one of humanity's most distant spacecraft, has been traveling away from Earth for nearly five decades. Yet even after all that time, it has covered only around 22 light-hours. The universe is so enormous that our greatest journeys barely register on its scale. We have reached the Moon. We have sent robots beyond the planets. We can detect galaxies from the early universe. But in terms of the cosmic ocean around us, humanity is still standing on the shoreline. Source: NASA Glenn Research Center, “Seeing the Earth, Moon, and Sun to Scale” (2023)

Elon Musk built a second internet above the first one. Nobody asked him to. Thousands of satellites orbit at 550 kilometers. Moving at 25 times the speed of sound. Talking to each other through lasers in the vacuum of space. Musk: “Thousands of satellites providing low latency, high-speed internet throughout the world.” Before Starlink, satellite internet lived at 36,000 kilometers. Geostationary orbit. Signals traveling a tenth of the way to the moon before bouncing back. The lag made it barely functional. Musk dropped the altitude by 98%. One decision rewrote the physics of an entire industry. But the altitude wasn’t the real play. Musk: “There are laser links between the satellites. It forms a laser mesh. The satellites can communicate between each other and provide connectivity even if the cables are cut.” Every internet connection you’ve ever used runs through cables. Fiber optic lines buried in soil. Dragged across ocean floors. Threaded through chokepoints that every military maps before anything else. A single anchor drop can black out a country. An earthquake can sever a continent. The entire digital world hangs from threads in the mud. Musk built a network that doesn’t touch the ground. No cables. No trenches. No ocean floor. No single point of failure. A constellation of machines whispering to each other through light at the edge of the atmosphere. The men who tried before him weren’t fools. Gates backed Teledesic at the height of Microsoft’s power. Motorola built Iridium with the best engineers alive. Both paid someone else to reach orbit. Both went to zero. Musk owned the rocket. SpaceX made launch reusable. Built the satellites in-house. Flew them on its own rockets. Owned every inch of the chain from factory floor to orbit. That isn’t a cost advantage. It’s a moat no one can cross without first building a rocket company from scratch. Starlink passed 10 million subscribers as a side project. Every telecom executive on Earth watched it happen. Not one of them can explain the architecture underneath. They think he built a better satellite company. He built the only network that survives when the ground gives out. And the ground always gives out.
