Vi vender noget af alt det, der er sket siden vi sidst optog midt på sommeren. 1: Space X - Flight 142: Nancy Grace Roman Space Telescope3: Månen har fået 2 nye kratere:3.1: Space Debris Impact Event Aug. 5th3.2: Asteroide impact: McGetchin Crater 4: Hvad hvis vi havde haft en månebase?5: Pga. 2024 YR4 som IKKE rammer Jorden i 2032--Topic 1: Starship Flight 14 – "It Finally Reached Orbit!" Yesterday, September 28, 2026, SpaceX launched Starship Flight 14 from Starbase, Texas, and achieved its biggest milestone in program history—Starship reached low Earth orbit for the very first time!The Drama (An Engine Fails): It almost didn't make it. During ascent, one of Starship’s six upper-stage engines shut down prematurely. Mission control briefly panicked, but since everything else was performing perfectly, they pushed through and fired the remaining engines to slip into orbit.The Payload (20x the Bandwidth): For the first time ever, Starship wasn't just a hollow test tank. It carried and successfully deployed an operational stack of 26 next-generation Starlink V3 satellites. SpaceX noted that deploying these huge new V3 satellites was equivalent to flying 20 Falcon 9 rockets at once in terms of bandwidth capacity.The Fiery Finish: SpaceX originally planned a 10-hour, 6-orbit flight, but cut it short to 3 hours for safety. Upon re-entry over the Pacific Ocean north of Hawaii, Starship completed a landing burn but tipped over and exploded into a massive fireball on the water.Space X 28.09.26 boiled down to 15min: https://www.youtube.com/watch?v=mSQnhKKmC1sTopic 2: The Nancy Grace Roman Space Telescope – "The Mother of Dark Matter"Just 4 weeks ago, on August 30, 2026, a SpaceX Falcon Heavy launched NASA's next flagship observatory, the Nancy Grace Roman Space Telescope. It is currently on a 3-month cruise to the Lagrange 2 (L2) point. Just days ago on September 25, NASA confirmed all global ground networks are officially locked in to receive its data.The Hardware (The T-Rex Analogy): The telescope is roughly the size of a city tour bus and weighs as much as a Tyrannosaurus Rex (about 4.1 metric tons). It uses a 2.4-meter mirror (the same size as Hubble's).The Superpower (100x Wider View): While it has the resolution of Hubble, its 300-megapixel wide-field infrared camera gives it a field of view 100 times larger than Hubble or JWST.If Hubble is looking through a narrow straw to examine a single pixel of the sky, Roman is a massive widescreen IMAX theater looking at the entire wall at once. It will map the universe 1,000 times faster than Hubble.The Mission: Because it can photograph hundreds of millions of galaxies in a fraction of the time, it is designed to track how dark matter clusters together and measure how dark energy is ripping the expansion of the universe apart. It will also down-link a crushing 1.4 terabytes of data every single dayThis new Space Telescope has a primary mirror gifted by the National Reconnaissance Office from an unused spy satellite program. Initial Steps: precise initial trajectory maneuvers have left the spacecraft with sufficient fuel reserves to potentially operate for over two decades rather than the originally budgeted ten years.

The Human-Made Impact: The SpaceX Falcon 9 CrashThe Event: On August 5, 2026, a spent 4-ton SpaceX Falcon 9 upper stage rocket crashed into the moon near Einstein Crater at about 8700 km/hBackstory: The rocket originally launched in January 2025 to deliver two commercial lunar landers (Firefly Aerospace's Blue Ghost-1 and iSpace's Hakuto-R). After completing its mission, it was left drifting in an unstable, highly elongated orbit until the combined gravitational pull of the Earth, Moon, and Sun pulled it in for an unavoidable crash. [1, 2]The Crater: The crash left an unintentional 18-meter wide and 3m deep crater.Scientific Value: The NASA LRO team had to precisely tilt the orbiter to photograph the spot, knowing that a timing error of just 10 seconds would miss the target by miles. Because scientists knew the exact mass and speed of the rocket, this accidental impact serves as a perfect controlled experiment to study how lunar soil reacts to high-velocity impacts. [Der er altid noget at lære, også selvom det måske ikke var med vilje]2. The McGetchin CraterThe Scale: The impact excavated a massive pit measuring 222 meters wide and 43 meters deep. This is the length of two football fields and deep enough to stack three city buses vertically.The Impactor: The culprit was a ...
