I just learned about the "Dolly Zoom" in an Electives class with Astronaut Ron Garan. This might ring a bell if you've seen Jaws. It's almost visual trickery that requires simultaneous zooming and pulling back a camera. The result is a central subject maintains its size while the background undergoes a surreal transformation. However, the real magic unfolded in today's class when Ron drew a parallel between the Dolly Zoom technique and the concept he terms the "orbital perspective." When we become fixated on short-term objectives, we unintentionally go into crisis mode. It's akin to a never-ending Dolly Zoom shot where we remain narrowly focused, missing out on the broader picture. To truly comprehend our place in the grand scheme of things, we have to let our immediate focus go, allowing us to witness what unfolds beyond our immediate viewpoint and see things from a different perspective. When we do this, we can achieve a more comprehensive understanding of our journey, whether through the lens of a camera, a spacecraft window, or the lens of life itself. #lifelonglearning

This explains why even in the underwater domain the presence of feature-poor areas (along with adverse visibility conditions) is one of the main factors complicating the realisation of robust and reliable visual odometry solutions.

Amazing video from #RonGaran, a former #NASA astronaut, where he explains perfectly the biggest flaw we have as humankind: we don't see ourselves as planetary. Provides a great reflection on how we should all change our mindset to a more interconnected, more communal one - and maybe then we'll be set on a better path to fix some of our more persisting (and more dangerous) problems like global warming, pollution, starvation and homelessness. We will stand on a more solid path to greatness, the day we understand that we cannot survive without the other and neither will our Earth, our only home in this vast universe. #JustOneEarth #awareness #climatechange #BigThink https://lnkd.in/dgUXrqkV

"This holiday special episode of This Week in Space covers a wide range of space topics from 2023, including asteroid sample return, China’s space achievements, commercial lunar landers, Mars sample return challenges, UFO disclosure, and more. Headlines: • The asteroid Bennu sample return mission delivers intriguing early findings, including organic molecules and “cauliflower” textured particles that may provide insights into the early solar system. • Speculative ideas on “dark life” forming from dark matter shortly after the Big Bang prompts discussion on expanding definitions of life. • Congress orders UFO records released within 25 years but allows military to withhold information threatening national security, disappointing those seeking full disclosure. Main Topic: The Year in Review • Recap of major SpaceX milestones in 2023 with Falcon 9 reuse and Starship testing advances, though the lunar landing variant and orbital refueling still need work. • India bounces back from previous lunar landing failure with successful Chandrayaan-3 orbiter and Pragyan rover mission. • Mars sample return mission faces criticism for ballooning costs now exceeding $11 billion and delays pushing to 2030 or beyond. • OSIRIS-REx asteroid sample return hailed as a major success story for 2023 despite minor parachute issue on re-entry. • Psyche and Lucy asteroid missions yield early surprises on unique asteroid properties. • China’s 2023 space achievements and future plans make it a program to watch with possible Mars sample returns, an increased pace of lunar landings, and more... maybe even sample sharing with the US! • ULA readies new Vulcan Centaur rocket for a January launch — it's a critical path to the moon with the first commercial lunar lander onboard. • Artemis delays provide cover for missing elements like SpaceX's lunar lander, orbital refueling tests, and lunar surface EVA suits. • Guest Leonard David covers latest intrigue around government UFO briefings and disclosure efforts."

Launched in December 2021, NASA - National Aeronautics and Space Administration’s James Webb Space Telescope has been capturing the most remarkable, never-before-seen images of space. How does it stay protected from the extreme temperatures in space? A custom sunshield, made with five layers of DuPont™ Kapton® polyimide film that are thinner than a human hair and measuring approximately the size of a tennis court, plays a large part in providing this high level of protection. Offering high resistance to heat, Kapton® film remains stable across a wide range of temperatures from -452°F to +752°F and doesn’t melt or burn. Thanks to this sunshield made with Kapton® film, the temperature of the James Webb Space Telescope remains constant and the sun’s heat is reflected back into space. The essential infrared cameras and instruments aboard must be kept very cold and out of the sun's heat and light to function properly. Watch this short video to learn more about the critical role Kapton® film plays in keeping the James Webb Space Telescope protected: http://spr.ly/6044PVZRg #NASA #Space #JamesWebbSpaceTelescope #Aerospace
