Hubble Space Telescope Demonstrates Operational Resilience with Innovative Pointing Mode In a testament to engineering ingenuity and adaptive problem-solving, NASA has successfully transitioned the Hubble Space Telescope to an alternate pointing mode following a gyroscope malfunction. This strategic shift ensures the continuation of Hubble's groundbreaking observations and potentially extends its operational lifespan. Key points:  ● Successful implementation of single-gyro mode  ● Minimal impact on scientific operations  ● Potential for exploring previously unreachable areas of the universe  ● Dr. Jennifer Wiseman, NASA scientist, notes: "The new pointing mode allows us to push the boundaries of what Hubble can observe, enabling us to explore previously unreachable areas of the universe with unprecedented clarity." This development underscores the importance of flexible design in space technology and the value of ongoing innovation in extending the life of critical scientific assets. How might this approach to problem-solving and adaptation be applied in other industries or technological fields?

Without proper gyroscope readings, the Hubble telescope can't point in the right direction. Can NASA fix this problem and resume Hubble's operations?

NASA just launched the James Webb Space Telescope, but which flagship telescope is next up? NASA is currently planning on launching the Nancy Grace Roman Space Telescope by May 2027, aimed at revealing some of the universe's mysteries! It currently hopes to leverage advanced instrumentation, like a Wide-Field Instrument capable of near-infrared imaging, as well as a Coronagraphic Instrument that can study exoplanets in a level of detail previously unseen before! Its field of view is expected to be over 100 times greater than that of the Hubble Space Telescope, enabling scientists to observe these star systems in ways never before seen. The future of space exploration is brighter than ever -- what are you looking forward to the most in the next 10 years of space exploration? _______________________________________________________________________________________ 👉 If you enjoyed this post, you'll love my newsletter - a 3-minute breakdown on the strategies that have helped space companies, startups, and missions soar to new heights. https://buff.ly/3xaJHKo #NASA #AdAstra

It's always the season for stargazing. Check out this star cluster that resembles a pine tree! 🌲 According to NASA - National Aeronautics and Space Administration, the cluster, officially known as NGC 2264, is a group of young stars in the Milky Way that is approximately 2,500 light years away from Earth.

Kepler-452b, often referred to as Earth's "cousin," is an exoplanet located approximately 1,400 light-years away in the constellation Cygnus. Discovered by NASA's Kepler Space Telescope in 2015, Kepler-452b orbits within the habitable zone of a G-type star similar to our Sun, known as Kepler-452. This means it is at a distance where liquid water could potentially exist on its surface, a key factor for the possibility of life as we know it. The planet is about 60% larger in diameter than Earth, making it a super-Earth, and it has an orbital period of 385 days. Despite these similarities, much remains unknown about its atmosphere, composition, and potential for habitability, as current technology does not yet allow for direct observation and analysis. اللَّهُمَّ بَارِكْ

NASA - National Aeronautics and Space Administration The Cigar Galaxy from Hubble and Webb (APOD: 2024 Apr 15) Image Credit: NASA, ESA, CSA, STScI, Alberto Bolatto (UMD) https://lnkd.in/gCmhCh6A Explanation: Something strange happened to this galaxy, but what? Known as the Cigar Galaxy and cataloged as M82, red glowing gas and dust are being cast out from the center. Although this starburst galaxy was surely stirred up by a recent pass near its neighbor, large spiral galaxy M81, this doesn't fully explain the source of the red-glowing outwardly expanding gas and dust. Evidence indicates that this material is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. In the featured images, a Hubble Space Telescope image in visible light is shown on the left, while a James Webb Space Telescope image of the central region in infrared light is shown on the right. Detailed inspection of the new Webb image shows, unexpectedly, that this red-glowing dust is associated with hot plasma. Research into the nature of this strange nearby galaxy will surely continue. https://www.nasa.gov/ https://www.esa.int/ https://www.asc-csa.gc.ca/ https://www.stsci.edu/ https://lnkd.in/gk7d7nwk https://www.astro.umd.edu/ Starship Asterisk* • APOD Discussion Page https://lnkd.in/gRXAdXs6 #APOD #NASA #ESA #Hubble #JamesWebb #JWST #cosmos #SpaceExploration #Science

Measurement errors tend to be quite costly. 🫰 🔬 Hubble Space Telescope Mirror Flaw (1990): When the Hubble Space Telescope was launched, it was discovered that its primary mirror had been ground to the incorrect shape due to a measurement error during manufacturing. The mirror was perfectly shaped but to the wrong prescription, causing the telescope's images to be blurry. ➡️ To correct the error, NASA launched a series of space shuttle missions to install corrective optics, costing approximately $1.5 billion. 💡Avoid errors in your processes - contact us today to discuss your Metrology and Inspection requirements! 🦸 #CostlyErrors #Metrology #MetrologyMatters #PrecisionEngineering #PrecisionManufacturing #QualityControl #QualityAssurance

Hubble Spots Black Hole Beam Causing Stellar Eruptions | NASA Goddard FriendsofNASA.org: In a surprise finding, astronomers, using NASA’s Hubble Space Telescope have discovered that the jet from a supermassive black hole at the core of M87, a huge galaxy 54 million light years away, seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but in a dangerous area near it. A nova erupts in a double-star system where an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. When the white dwarf has collected a big enough layer of hydrogen, it explodes out into space.

"NASA's Next Big Thing: The Nancy Grace Roman Space Telescope Ori Fox, Space Telescope Science Institute. NASA's upcoming Nancy Grace Roman Space Telescope is readying for launch in late 2026. Roman will be able to survey the sky 1,000 times faster than Hubble. It will collect near-infrared imaging and spectroscopic data with Hubble-quality resolution and sensitivity over fields of view 200 times greater than Hubble. Roman's data will enrich all areas of astrophysics by enabling studies of nearly every class of astronomical object, phenomenon, and environment across the observable universe. Dr. Fox will discuss the details of the Roman mission, with a focus on its scientific goals. These exciting studies include the discovery of thousands of new planets and pinpointing the source of a mysterious force called dark energy that permeates our universe."
