NASA’s Ingenuity helicopter sent its final signals to Earth in the earlier part of the year. Engineers have been studying these and have started to piece together a picture of events that led up to its final flight. They concluded that data provided by the navigation system was inaccurate leading to a chain of events that caused its ultimate demise. One of the biggest problems it seems is that the terrain was smooth leading to a lack of landmarks during Flight 72. Mars is the fourth planet from the Sun and is well known for its distinctive red colour. It’s surface is is covered in iron-oxide which is known by the more common name – rust. The planet is just over half the size of the Earth and has some fascinating geological features like Olympus Mons, the largest volcano in the Solar System. Valles Marineris is a canyon system which stretches thousands of kilometres and dwarfs the Grand Canyon. The atmosphere of the planet is mostly composed of carbon dioxide and currently incapable of supporting life. It’s not thought this has not always been the case and its missions like Mars 2020 that have helped to unravel the mysteries of the red planet.  A full-disk view of Mars, courtesy of VMC. Credit: ESA The Perseverance Rover and Ingenuity helicopter were both part of the Mars 2020 mission and have been exploring Mars since their launch in 2020 atop an Atlas V rocket. Ingenuity became the first robotic rotorcraft that undertook powered flight in the Martian atmosphere. The inaugural flight took place on 19 April 2021 the 1.8 kilogram drone took off under the power of two counter-rotating blades. The blades of the drone are 1.2m long, oversized by Earth standards but the atmosphere is only 1% as dense as Earth so larger than usual blades are needed.  Image of the Mars Ingenuity helicopter (Source : NASA) Flight 72 was scheduled for the 18th January this year and there was nothing special about it. The plan was a brief vertical hop to checkout the flight systems and to grab some photographs of the area. The flight data revealed it reached an altitude of 12 metres, took the images and was back on the surface after 32 seconds but had severed communications. After communications  was re-established, it was discovered that Ingenuity had sustained damage to its rotors.  Now, almost a year after the incident, a team of engineers from NASA’s Jet Propulsion Laboratory have been analysing the data. Their findings will be published in the next few weeks however the team of engineers assert it was harder than expected to complete an accident investigation from 160 million kilometres. The faults lie in the navigation system that was designed to visually track surface features using a camera pointed at the round. The system worked during early flights over more textured terrain but as Ingenuity moved over the Jezero Crater, it began operating over featureless sand ripples.  The navigation system was designed to provide estimates of the helicopter’s velocity, chiefly to enable it to land. The data revealed from Flight 72 revealed that the navigation system couldn’t find features to track. Images showed that the lack of features led to a harden than usual touchdown leading to a pitch and roll of the craft. The sudden change of attitude led to increase load on the rotors, beyond their designed limits leading to the structural damage.  Even though Ingenuity will not be able to fly anymore it can still provide weather and avionics data to the Perseverance rover. It will help us to understand more about the weather in its vicinity but perhaps its greatest legacy are its hours of flight on an alien world.  Source : NASA Performs First Aircraft Accident Investigation on Another World The post NASA Thinks it Knows Why Ingenuity Crashed on Mars appeared first on Universe Today.

Chris and Bre Giglio run a popular parenting TikTok with nearly 200,000 followers. Some of their most popular posts have been about what Chris calls his "mornings with the girls." "Nearly every morning for over 3 years I've gotten up with our girls so Bre can get the sleep deserves after she gave so much to grow our little family," he captioned one such video. It shows him up at the crack of dawn cleaning up the kitchen, folding laundry, and making his daughters breakfast.But Chris noticed a peculiar response he'd often get when he posted about his morning routine. While people were mostly excited to see a dad taking good care of the girls in his life, others took the opportunity to ask prying questions about Bre. "Does she ever let you sleep in? Just wondering if you ever have 'you' days?" one user asked relatively politely. Others commenters aren't so kind, asking essentially, if Bre doesn't get up with the kids, what does she even do?Chris took a moment to respond to the questions in a recent video, and the response perfectly encapsulates what a partnership should look like."I've gotten up with my daughters every morning since they were born because that's what has worked best for us. But for some reason if I share about that for long enough, someone's going to ask a variation of the question, but what does she do for you?" he says."... that question also gets me feeling like we can sometimes forget what marriage is all about."He goes on to talk about how he's a morning person who loves getting up on the early side. Since he sometimes has to work late, he looks forward to having that guaranteed time with the kids. His wife, on the other hand, is a night owl and does her best work in the evening — so it just wouldn't make sense for them to flip-flop just because of "fairness.""I do these things because I love her and I wanna make her life better, not because I'm looking to stack up a tower of I-owe-you chips."Watch the rest of Chris' excellent response in the TikTok here: @chrisandbre.g Replying to @Magen Bostwick there’s no scorecard in marriage, which is also why @Bre Giglio and I can both be winners #marriage #married #marriagetok #marriedtiktok #marriagegoals In the caption of the post, Chris wrote: "There's no scorecard in marriage, which is why Bre and I can both be winners."Chris and Bre have figured out an incredibly important concept when it comes to making a marriage last: Equality and equity are not the same thing.Equality refers to when people are treated exactly the same regardless of needs, preferences, resources, etc. Equity is a concept that means everyone gets what they need to reach an equal outcome.Trying to enact perfect equality in a marriage as parents can create a mess. Making sure each partner has an equal number of early wakeups every week, takes turns folding the laundry, contributes identically to the cooking and dishes and meal plan. It's impossible to get right, unsustainable, and inevitably leads to arguments when the score isn't perfectly settled.Equity looks like Chris' videos. He takes the early shift with the kids because he doesn't mind doing it and is better suited to the mornings. That's his thing, and it frees his wife up to contribute to the household in a way that suits her own strengths. As long as both partners are pulling their weight, that's how it ought to be done.The response to Chris' morning videos also raise another issue: Few people would ever accuse a dad of being lazy if his wife was excited to let him sleep in while she cooked breakfast. The double standard is outrageous and it doesn't do anyone any favors. It should be super normal to see a dad picking up a big chunk of the load at home, not a rarity.Fortunately, most of Chris and Bre's followers are totally on board with their approach:"marriage isn’t about keeping score. when both ppl give 100% to each other, no one feels like they’re slipping through the cracks ❤️it’s honestly the best," one commenter wrote."True love is splitting the chores fairly but not 50/50. My wife does most of the laundry, i hate it and she doesn't mind meanwhile I cook most of the time because she hates it and I like it. It works because it works for you both," said another."100% and if it was the other way around no one would ask what she does for you ?" added another.We love seeing a dad go out of his way to spend extra time with his kids rather than treat is as an obligation. As a night owl myself, it makes me want to crank that alarm back a few hours and pop out of bed to whip up pancakes before my kids are up — well, almost.

We know that even a 10 minute power nap can do wonders for our energy levels. And yet, for many of us, the thought of being able to get proper rest within a mere ten minutes might seem like a far off distance dream. However, maybe it’s because we don’t realize that a 10 minute power nap requires a slightly different strategy than our nighttime sleep. As Dr. Joe Whittington, aka Dr. Joe MD on TikTok, explained, there’s a “Navy SEAL-inspired power napping technique that many of our elite forces swear by,” that can have folks actually feeling refreshed in a fraction of the time. But here’s the thing— you have to position yourself a certain way. In the clip, Dr. Joe suggests finding the edge of a bed or couch, and lying down so that your legs are propped up on the elevated surface at a ninety-degree angle. In the demonstration he also has his hands folded on his abdomen. “Laying in this position for 10 minutes is going to accomplish two things,” he says. “First, it’s going to reduce swelling in your legs as well as return blood flow to your core. Both of these are going to trigger relaxation."“Second," he continues, "by limiting the time to 10 minutes, you will wake up during the light phase of sleep and therefore wake up feeling refreshed.” @drjoe_md Here's a Navy SEAL-inspired hack for a quick energy boost: take a 10-minute power nap with your legs elevated. This position promotes blood flow back to your core, reducing swelling in your legs and triggering relaxation. Studies show that short naps improve alertness and mood without the grogginess of deeper sleep. This trick is ideal for a fast reset when you're low on time, helping you feel refreshed and ready to tackle the rest of your day. #lowenergy #naptime #sleeptips #healthtips #doctoradvice @Braden Wellman ♬ original sound - Dr. Joe, M.D. ? As pointed out by the New York Post, this technique was first introduced to the mainstream by Retired Navy SEAL Jocko Willink, who boasted to Business Insider that his personal power naps are capped at 8 minutes. Of course he apparently can resist free pizza and donuts, so the man is clearly superhuman. boy in gray hoodie lying on black leather couch Photo by Alexander Grey on Unsplash You’ll also find this hack touted in a world nearly polar opposite of the military—theatre. In the Alexander Technique, which is form of body awareness training that focuses on improving posture and reducing tension, performers and students will engage in constructive rest, (sometimes known as “active rest”, “semi-supine” or the “Alexander lying-down position”) by lying on the floor with their knees elevated. Of course, Frederick Matthias Alexander likely got this pose from the ancient practice of yoga. Regardless of where this trick came from, it’s easy to see how folks from all walks of life can easily incorporate it into their routine when they need an energy boost. Which, let’s face it, is pretty much all of us. In a Gallup poll released in April, 57% of Americans said they would feel better if they could get more sleep. Luckily Dr. Joe has all kinds of helpful content in the realm of health education, including even more sleep tips. Previously the doc explained why those pesky mid-sleep involuntary jerks happen (and how to prevent them), as well as the benefits of cognitive shuffling when you can’t seem to quiet your mind at night. Maybe this knowledge is the key to finally getting those elusive eight hours. But if a power nap is all you have time for, then channel your inner Navy SEAL. a sea lion resting on a wooden dock Photo by Michael Obeysekera on Unsplash

Society often portrays men as logical creatures who are good problem solvers because they don't have all these emotions that get in the way. It's something that's often wielded as this superpower that men have over their female counterparts. This isn't anything of men's doing, at least not men from the last several generations. This "logical non-emotional" stereotype was thrust upon them in much the same way as the stereotype that women are "too emotional" and borderline hysterical when things don't go their way. There's no getting around bumping into this general thought process or at least the remnants of it on a near daily basis. Because it's so prevalent in societal norms in much of the western world, men and women subconsciously internalize these things. But anyone who has raised both genders are aware that boys and girls are equally as emotional, it's just that they start receiving very different messages about that emotionality from a very early age. Starting around preschool age boys begin to hear, "big boys don't cry" while they watch their younger sister or classmate receive comforting and kind words when they begin to cry. When it comes to young girls, they're often given more responsibilities at an earlier age whether it's teachers picking girls more often for "classroom helper" or parents focusing more on their daughter cleaning up after themselves than their sons because "boys are messy." Toughen Up Pop Tv GIF by Big Brother After Dark Giphy Many examples of this exist so before too long it would seem that both genders are getting gendered messaging about themselves and each other. But in recent years there has been a shift in people wanting men to get in touch with their emotions as to not feed into the societal American norm of toxic masculinity. This focus on men's emotional well-being comes on the heels of research showing the harmful effects of enforcing restrictive gender roles. According to United Way, "restrictive gender norms often limit children’s potential and opportunities, affect their self-esteem and mental health, and shape their relationships with peers."As society shifts to be more flexible with gender norms, men are beginning to not only admit to having feelings other than anger or happiness, but are expressing them. Or at least, they're attempting to express them according to the overwhelming repetitive response to a question posed on Reddit. A user asks, "men, why do you say you're fine when you're not" and the answers were heartbreaking. Im Fine Episode 2 GIF by Friends Giphy One person responds with, "Because I think most believe that nobody truly gives a f*ck," which was quickly backed up by others with personal stories. Another shares, "Honestly, no one really listens. You get about five words in and people decide where they think you’re going with this. Then they talk about that thing instead of what you’re talking about no matter what you say. Its usually easier for me to work through and process things myself than put the effort into fighting to be understood.""My wife and I are having this problem right now. She finally blew up at me and said I don't talk to her anymore and I told her it's because she doesn't listen. I'll explain my thoughts or intentions in deep detail, but after the first 10 words or so she thinks she totally understands and tunes out everything else. Which ends up being cyclical, because she'll get mad that I didn't tell her something when in fact I did. Just easier to not say anything at all at this point, or keep answers to one subject and 10 words or less," someone chimes in adding to the sentiment of not being heard. Season 3 Hug GIF by Black Sails Giphy One man explains the rules he has learned, "My entire life as a man, I've been taught two things. I need to be coming up with solutions to problems. And if I'm not useful, I'm useless. The moment I ask for help or show that I need help with a problem rather than being the one helping with a problem, I am then regarded as the problem. When I am the problem, I'm not useful; see above."Another reveals expressing emotions results in him comforting others, "Because if I tell you I'm not fine, it inexplicably somehow turns into me trying to comfort and reassure you. No, it's not because of you. No I'm not mad that you thought this was all about you. Well you shouldn't feel guilty. I'm sorry you're upset now. Of course I still love you. I'm sorry for upsetting you, honey. No, I promise I'm fine. Everything is perfect."Men are listening to women and others telling them to open up about their emotions but their seems to be an important component missing. There are therapists that specialize in helping men achieve emotional intelligence and communication of their emotional needs. But it will take further shifting in societal consciousness to recognize when men are being vulnerable with their needs. This isn't just a men problem, it's a social conditioning problem that needs to be dismantled as one person points out by saying, "ironically sometimes women still subconsciously carry the sexist belief that men should have better control over their emotions." Unlearning something that is ingrained in all aspects of society takes time as does learning to tap into and express feelings that were once equated to weakness. Everyone is learning and giving grace and understanding can go a long way to figuring things out.
