Unsung Hero of the Moon Landings - The Saturn V Instrument Unit 🚀🌙 The Saturn V rocket that carried astronauts to the Moon had a crucial component hidden from view - the Instrument Unit. This ring-shaped structure 🔘 contained the guidance system that steered the massive rocket on its trajectory to the lunar surface. Designed by NASA 🛰️ and built by IBM, the Instrument Unit was a marvel of 1960s technology. It housed a digital computer, inertial guidance platform, accelerometers, and other electronics to precisely control the rocket's flight. Without this unsung hero, the historic Apollo missions would not have been possible. 🚀🌕 One of the original Instrument Units is now on display at the Smithsonian's Udvar-Hazy Center, a testament to the engineering brilliance 🧠 that propelled humanity to new heights. Next time you learn about the Saturn V, remember the vital role of the Instrument Unit in making those moon landings a reality. 🌐🌍 https://lnkd.in/ebtmbHhz #SaturnV #InstrumentUnit #Apollo #NASA #Space #Engineering #History 🚀🛸🌘

Did you know that NASA’s Perseverance Rover is equipped with G&H’s cutting-edge acousto-optic tunable filters (AOTF) as part of its SuperCam? 🛰 Our AOTFs are specially engineered to select specific wavelengths with precision, ensuring high performance for distant imaging and analysis. Key features of our AOTFs include excellent out-of-based suppression, high damage threshold, improved thermal management, and superior beam quality. With a wavelength range from UV through mid-IR and resolution bandwidths of less than 1nm, our AOTFs are the perfect choice for your next project. Join us at Booth #425 at SPIE Optics + Photonics to explore how G&H’s acousto-optic tunable filters can enhance your applications. #ABetterWorldWithPhotonics #GandH #AOTF #AcoustoOptics #SPIEOpticsPhotonics #NASA #PerserveranceRover #Imaging #ThermalManagement

"The collaboration with NASA brings another tool to bear: imaging spectrometers. These advanced optical instruments need to stay cold as they fly high. From cryogenic vacuum chambers on planes or spacecraft, they detect hundreds of wavelengths of light — from the visible to shortwave infrared — reflected off planetary surfaces. The technology is now being used to help identify surface minerals across dry, treeless expanses of the Western U.S." #remotesensing #hyperspectral #minerals

Rocket Lab: The Year 2024 in Review: Our Biggest Year Yet Rocket Lab's Electron FriendsofNASA.org: Electron is the "only reusable orbital-class small rocket". Electron’s first stage design provides higher launch frequency and lower launch costs. Rocket Lab's Rutherford Engine is the "world’s first 3D-printed, electric-pump-fed rocket engine." Rocket Lab was founded in New Zealand in 2006. Rocket Lab currently launches from the Mid-Atlantic Regional Spaceport in Wallops Island, Virginia, USA, and from the Māhia Peninsula on New Zealand's North Island.

Spacecraft Makers: NASA SPHEREx—Intense Tests Preparing it for Space | JPL FriendsofNASA.org: Go behind the scenes with the team working on NASA’s SPHEREx space telescope as they talk through their rigorous testing process. Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx aims to capture millions of stars and galaxies in 102 colors, creating a unique 3D map to uncover clues about the universe’s origins. This video features Farah Alibay, a SPHEREx systems engineer at NASA’s Jet Propulsion Laboratory, and Brian Pramann, SPHEREx program manager at BAE Systems. Learn about the special facilities required for SPHEREx’s critical environmental tests, including thermal, acoustic, vibration, and electromagnetic interference and compatibility testing. NASA is targeting late February 2025 for the launch of SPHEREx, which will lift off aboard a SpaceX Falcon 9 rocket from Vandenberg in California.

X POINTS (NATURAL PORTALS) ACCORDING TO NASA STUDY: This is a NASA article based on their research, written in TERMINOLOGY that makes it understandable to the common man. X marks the SPOT OF MAGNETIC RECONNECTION, creating PORTALS OR OPENINGS where the solar wind can enter Earth's magnetic field. Mingling lines of magnetic force from the sun and Earth CRISS-CROSS AND JOIN to create the openings. "X-points" are, therefore, WHERE CRISS-CROSS of magnetic forces from the sun and Earth TAKE PLACE. #xpoints #naturalportals #naša #equilibrium #jasnicaklaramatic

Deadly Million degree Plasma around the Earth. 1. In the Earth’s radiation belts there are swaths of charged particles trapped in Earth's magnetic shield, or #magnetosphere. 2. Special cameras are used to capture this phenomenon. Unlike traditional cameras that rely on light, these cameras use special sensors to capture energetic neutral atoms emitted by charged particles interacting with the extended atmospheric hydrogen gas surrounding #Earth. 3. This image of the million-degree hot #plasma halo encircling Earth, was captured by #ESA’s #Juice spacecraft with the help of #NASA's #JENI payload during its lunar-Earth gravity assist on its way to the icy moons of #Jupiter.

On Christmas Eve day, NASA’s Parker Solar Probe passed within 3.8 million miles of the Sun’s surface, penetrating its solar atmosphere (corona) to collect incredibly valuable data unavailable from a greater distance. This is the closest any probe has ever come to the Sun, and it is expected to produce tons of enlightening information about solar physics. https://lnkd.in/eVCT9hP2 #SpaceExploration #SolarPhysics #NASA #TheSun #SolarProbe
