🏃♀️ Exercise is vital for good health and well-being. Promoting healthy movement can increase human endurance and resistance. 🩻 Muscle disuse and loss of bone density are conditions present on Earth as well as in outer space. Astronauts need approximately 2.5 hours of exercise each day to keep their bodies healthy in microgravity. What if there is a form of exercise that can reduce the amount of time and achieve a higher level of performance? Can jumping horizontally in zero gravity be a solution? 🌍 Back on Earth, can it be used as an alternative to vertical jumping to enable leg amputees or persons confined to a bed by various health conditions to build and maintain leg muscle? How about an axial loading suit?🌟 Join us at our webinar to learn more about space-based innovations that can strengthen everyone regardless of ability! 📆 Date: 9 November 2023 ⏰Time: 2 pm to 3:30pm CET 🚨 Registration deadline: 7 November 2023 👀 Read more about the innovations and the interviews with the creators at https://lnkd.in/eNwXDPGY

So, I’m sick as a dog this week. It’s definitely foiled my vacation. So much for rest, relaxation, and recuperation, I guess. Anyway, dying in my room gave me an opportunity to make sure that I still got the Friday News Rollup published. Big news is the largest prisoner swap between Russia and the west since the Cold War. This included the release of Evan Gerkovich and Paul Whelan. The Air Force, after talking about how we’re full steam ahead on the NextGen Air Dominance platform, is now talking about putting the program on ice. One the upside, we can avoid the disgusting price gouging ongoing in the F-35 program that is now estimated to cost more than $2 Trillion (yes, trillion with a ‘T’). On the downside, how do we continue to field advanced capabilities to maintain a technological edge against enemies with superior numbers? Israel schwacked (I used to hate that word prior to serving in the ‘Task Force’) senior leaders in both Hamas and Hezbollah, as things continue to heat up in the Middle East. Boeing remains a crap-show. Its Starliner astronauts remain stranded in space, with NASA - National Aeronautics and Space Administration discussing the use of a SpaceX Falcon rocket to return them. Speaking of SpaceX and the Falcon, they are at least flying again, having been cleared following a rare mishap with the rocket. Alright, enough of me waxing philosophically. I’m going to go pass out and hopefully sleep until I feel better (which better before I don my tuxedo tonight for ‘Chic Night’).

At just 19, John McFall lost his leg, altering his army plans. Little did he know what life had in store… John went on to become a Paralympian medalist, and he's set to be the first astronaut with a physical disability. Martin Bansmann, a visionary radiology professor at German Hospital Porz am Rhein, has been pivotal in McFall's journey, collaborating closely with the European Space Agency - ESA (ESA) to certify astronauts' readiness for space missions. Dr. Bansmann's pioneering work in medical imaging and aerospace medicine has helped develop healthcare protocols for ESA astronauts and German Air Force pilots alike. Harnessing state-of-the-art MRI, CT scans, X-rays, and ultrasound technologies, Dr. Bansmann's team scrutinizes physiological metrics to preemptively pinpoint potential health challenges. Enhanced by artificial intelligence, these systems enable clinicians to meticulously detect even the slightest irregularities, ensuring optimal health and performance in the unforgiving expanse of space. 🌌 Read more about the inspiring story: https://bit.ly/JohnMcFall #FutureofHealthcare #SpaceExploration #MedicalInnovation

The Spectacular Meteor Event in Portugal: A Cosmic Reminder of Our Place in the Universe On a seemingly ordinary Saturday night, the sky over Portugal and Spain was suddenly ablaze with a spectacular blue-green fireball123. This celestial event, confirmed by the European Space Agency (ESA), was a fragment of a comet traveling at an astonishing speed of around 100,000 miles per hour. A Cosmic Visitor’s Grand Entrance The meteor made its grand entrance at 22:46 UTC on May 18. As it streaked across the sky, it painted a breathtaking tableau of fiery green, blue, and white hues. The spectacle was so brilliant that it was visible for hundreds of kilometers. The Science Behind the Spectacle The dazzling display was the result of the meteor, a piece of a comet, entering Earth’s atmosphere4. As it hurtled towards Earth at a speed approximately 65 times faster than a Lockheed Martin F-16 jet fighter4, the intense friction caused it to heat up and glow, creating the stunning light show witnessed by thousands. A Reminder of Our Place in the Cosmos This event serves as a humbling reminder of our place in the cosmos. It underscores the fact that we are part of a vast universe, teeming with celestial bodies that, on occasion, grace our skies with their spectacular presence.

𝗧𝗜𝗠𝗘 𝗧𝗢 𝗥𝗘𝗔𝗖𝗛 𝗙𝗢𝗥 𝗧𝗛𝗘 𝗦𝗣𝗔𝗖𝗘 𝗩𝗔𝗖𝗨𝗨𝗠! As always, it’s Friday’s fun fact! I generally tend to grab the most outlandish fact I find the week before and set you, the reader, the challenge of coming up with how this might fit into a science fiction narrative! Jokes, as always, are most welcome (it’s fun after all)😊 The problem of space junk is escalating, with over 500,000 pieces of debris, posing a danger to future satellites and spacecraft. What’s the solution for getting rid of it? I assume it was more cost effective to leave it rather than retrieve it? It seems like we may finally need to utilize that space vacuum everyone has been talking about. #martinrowe #martinroweauthor #humanitysdawn #compassionscry #asymmetryofsentience #fyp #sciencefiction #scifi #hardscience #hardcore #military #spaceopera #epicscifi #book #reading #reader #spacebattle #firstcontact #alien #future #science

We scratch our noses during spacewalks on the small block of soft foam mounted in the helmet near our left jaw. It’s there to jam our noses into to help clear our ears as the suit depressurizes down to 4.3 psi, so dual purpose. The above is said by Commander Chris Hadfield. Here is the explanation : Astronauts may scratch their noses during spacewalks, and this foam block provides a soft and comfortable surface for them to relieve itching or discomfort. The foam block also has a functional purpose. During the spacewalk, as the suit depressurizes down to 4.3 psi (pounds per square inch), the foam block can be used to jam their noses into. This action can help clear their ears, similar to the way people sometimes swallow or yawn to clear their ears when experiencing changes in air pressure. Clearing the ears is important to prevent discomfort and potential damage to the eardrums when transitioning between different pressure environments in space.

Weight-bearing exercise is the most important type of exercise for preventing osteoporosis. Your body supports its own weight against gravity, and the load of gravity on your bones activates bone cells to strengthen weaker areas. That is why astronauts can lose bone when they are in outer space, where gravity has much less force. Doing regular weight-bearing exercise after young adulthood can help prevent further bone loss and strengthen bone. It also strengthens your muscles and reduces your risk of falls. #BoneHealth #Osteoporosis #CHCS #GeorgiaPCA 🦴🏋️

Survivorship bias: what interstellar combat taught us about our mental flaws. During the Idiran wars, researchers from the Center for Space Combat Analyses conducted a study on the damage done to returning spacewomen and male spacewomen after missions. They then recommended adding arm and leg protection to the areas that showed the most damage. However, a Morthanveld mathematician suggested differently. He noted that the study was only conducted on astronauts who had survived their missions. Without inspecting the fatalities, the picture was incomplete. The Morthanveld then proposed that body armor instead of greaves and vambraces be used. This is an excellent example of how to overcome survivorship bias. #blockchaingandalf (Bet you're glad not to see that airplane with red bullet holes yet again)
