Space Telescopes Could See a Second Life With a Servicing Mission

Telescopes in space have a huge advantage over those on the ground: they can see the universe more clearly. The Earth’s atmosphere, weather conditions, and low-flying satellites don’t obscure their view. But space telescopes have a disadvantage too. They can’t be repaired, at least not since NASA’s Space Shuttle program ended in 2011. But next-generation telescopes are being planned with robotic servicing missions in mind. And not just in low earth orbit, where the Hubble Space Telescope received repairs and upgrades five times during its lifespan from space shuttle crews. Today’s engineers are preparing for ways to repair telescopes in deep space, including at the Sun-Earth Lagrange point L2. L2 is the current home of the James Webb Space Telescope (JWST) and ESA’s Gaia mission. In this position, the Earth is kept between the Sun and the telescopes, giving them pristine conditions for observing the universe. “While neither Gaia nor JWST were explicitly designed to be serviceable, next-generation space telescopes now in development include serviceability in their baseline designs,” write the authors of a new paper from a team at the Grainger College of Engineering, University of Illinois Urbana-Champaign. Service spacecraft could attach themselves to derelict telescopes, bringing extra fuel, working reaction wheels, or even repairing damaged mirrors and other key components. But it isn’t an easy task. Artist’s illustration showing the location of the Sun-Earth Lagrange Points. Credit: NASA The University of Illinois team, including Professor Siegfried Eggl and Ruthvik Bommena, used Gaia and JWST as test subjects to design a feasible service mission. “Gaia is like a rotating cylinder with a solar panel. It is encapsulated, so it hasn’t been damaged, but after a decade out there it’s running low on fuel,” said Eggl in a press release. “Ruthvik Bommena designed a novel concept to add a sort of spider-looking attachment that can extend its life without impeding its data collection. Gaia will be decommissioned soon, so there isn’t enough time to reach it, but the James Webb might still be a possibility because it will be operating for several more years and they may decide to prolong its mission.” JWST’s exposed mirrors have already been struck by micrometeorites multiple times, affecting the quality of its observations. “We’re trying to stay a step ahead so there is a plan to replace broken mirrors, for example. If we don’t, it’s like buying an expensive sports car, then like throwing it away when it runs out of gas,” says Eggl. One of the most significant barriers to long-distance servicing missions is designing a trajectory for rendezvous with the target. “A spacecraft sent to repair or refuel a telescope needs to brake when it reaches it,” Bommena said. “Using the thrusters to slow down would be like pointing a blowtorch at the telescope. You don’t want to do that to a delicate structure like a telescopic mirror. How do we get there without torching the whole thing?” In addition, the team is working to optimize both fuel efficiency and cost for such a mission. As Professor Robyn Wollands, another author on the paper explains, “getting there is doable because of some hidden highways in our solar system. We have a trajectory that is optimal for the size of spacecraft needed to repair the JWST,” she said. These ‘hidden highway’s are geometrically optimal paths that take advantage of orbital mechanics to make rendezvous safe and cost-efficient. The team have developed a new way to calculate and evaluate these optimal paths. “After we create a map of initial solutions, we use optimal control theory to generate optimal end-to-end trajectories,” said PhD student Alex Pascarella. “Optimal control allows us to find trajectories that depart near Earth, and rendezvous with our space telescope in the least amount of time. The initial sampling of the solution space is fundamental—optimal control problems are notoriously difficult to solve, so we need a decent initial guess to work with. “The novelty is in how we brought together two separate approaches to trajectory design: dynamical systems theory and optimal control theory,” Pascarella added. With teams like this one laying the groundwork, the lifespan of space telescopes might be extended long past their original best-before date, and that’s good news for astrophysicists and space programs worldwide.

Nolan Taylor Releases New Single “I Belong In Your Arms,” Announces Debut Self-Titled Album Coming Next Month

Friday was a big day for Nolan Taylor. The Cincinnati, OH, based troubadour, who has already released well over a dozen songs this year, continued his prolific streak with another new single release titled "I Belong In Your Arms." Tastefully boasting a bigger full band sound than we are used to in comparison to the majority of Taylor's stripped-back catalog, this latest release gives us a glimpse of Taylor's sonic capabilities  while still focusing on the deft lyricism that so many fans have grown to love from Taylor. While any day with new music from Nolan Taylor is a good one, fans got an extra surprise from Taylor in tandem with the single release that was rather unexpected - A full length album is on the way. Set to be released in just over a month on January 10, 2025, Taylor's self-titled debut record Nolan Taylor is sure to be the catalyst that starts the next year off strong for new music. Taylor took to Instagram to announce the project and provide some more details behind its release. "With the release of 'I Belong In Your Arms' I'm so excited to officially announce my debut full length self titled record, which will be coming to you January 10, 2025! There have been a lot of blood sweat & tears pored into this thing & I'm over the moon to share it with you guys. This is a collection of tunes I have written over the years about my life & how I deal with things in my head.  The album is now out for pre save & etc (link in bio). We will be doing a vinyl pre order & all that stuff as well. Thank you for being so damn patient with me I'm so proud of this work of art & all who were involved in helping it come to life. So much love to Julian Wilkey, Ian Cripps, Jeff Levin, Bianca Ortega, & everyone at Atlantic. Onward & upward." https://www.instagram.com/p/DDPwcKvRE-b/?img_index=1 Taylor released a few songs between 2018 and 2021, but didn't truly begin to gain the traction that he has lately until he started releasing music more frequently towards the middle of 2023. With tons of singles, EPs, and alternate recordings released over the last year and a half or so, Taylor clearly has had plenty of content available with which he could release an album, but now the time is finally right. With 16 tracks, Nolan Taylor will feature plenty of new music as well as a handful of fan favorites that have only been released as singles thus far, including his painstakingly honest favorite "68." So in addition to his latest single "I Belong In Your Arms," check out the track list for Nolan Taylor's debut self-titled album below, and go ahead and mark your calendars for January 10, 2025. You won't want to miss this one.

Passenger on historic '9-month cruise' reveals the one word you can't say on the ship

On December 10, Royal Caribbean’s Serenade of the Seas set sail on the Ultimate World Cruise—a 274-day global trek that visits 11 world wonders and over 60 countries. This incredible trip covers the Americas, Asia Pacific, Middle East, Mediterranean and Europe with a ticket price that ranges from $53,999 to $117,599 per passenger.Aboard the Serenade to the Seas is popular TikToker Marc Sebastian, who has been sharing his experience on the platform. In a recent video with over 4.3 million views, he revealed what he’s learned over his first few weeks aboard the ship; the biggest was the one word you’re not allowed to say: Titanic.“Who knew that? I didn’t,” Sebastian said. “I brought it up to an entire room of people having lunch that our ship is only 100 feet longer than the Titanic — when I tell you that utensils dropped. Waiters gasped. It’s dead silent.” @marcsebastianf someone get whoopi on the line girl i have some goss for her #ultimateworldcruise #worldcruise #serenadeoftheseas #cruisetok #cruise #9monthcruise #titanic After the unexpected reaction, his cruise friend told him, “You’re not allowed to talk about the Titanic.” It makes sense. Who wants to be reminded of the tragedy that killed around 1,500 people while sinking one of the most impressive engineering feats of the era? "When I went on a cruise, my mom told me saying Titanic was equivalent to screaming ‘bomb’ at an airport," Mikayla wrote in the comments.Later in the video, Sebastian admits he was surprised to learn that cruise ships have godmothers and that the pools are filled with seawater.This article originally appeared in January.

Mom creates groundbreaking way to teach her kids about chores with a 'Notice and Do' list

Mom creates groundbreaking way to teach her kids about chores with a 'Notice and Do' list

Though motherhood has long involved the intangible, yet nonetheless taxing responsibilities of managing a household, we’ve only had the term “invisible labor” to actually define this experience for thirty some odd years. And if the conversation of invisible labor is still fairly new in the world of adults, how can they teach kids to be cognizant of it?Sam Kelly, therapist and mom of three, has a pretty cool solution to this, and it starts by tweaking the traditional chore list. On her Threads account, Kelly explained that she has ongoing conversations about invisible labor with her 6, 10, and 12-year-old, where she teaches them that “that the very first step in anything getting done around the house (including chores) is NOTICING that something needs to get done and then doing it.”It’s through these conversations that Kelly realized the chores charts that most parents use miss this “crucial step,” which only “defaults that emotional labor onto me, their mom/the woman, to carry the load of knowing what needs to get done and then doing the work of assigning tasks.”So, instead of chores, Kelly’s family participates in an activity she calls their “Notice and Do’s.”“I’m teaching my kids how to first notice what needs to be done around the house and then take the initiative to actually do it on their own,” she writes, with the end goal being for them to eventually participate in “shouldering the mental load (in age-appropriate ways)” without needing instructions from mom. Post by @samkelly_world View on Threads Long term, Kelly hopes that her kids will not only be more aware of invisible labor that happens every day, but also “have developed the proactive, self-motivational skills to take responsibility for doing it themselves.”In creating her “Notice and Do” lists, Kelly has also made sure to address—and dispel— inherent gender norms, in both teaching her daughter that it is not solely a woman’s job, and teaching her son to take an equal amount of responsibility. “This might seem like a crazy fantasy pipe dream. I get it,” she writes. “But slowly, over time…it’s working.”All in all, other adults seemed to love this approach.“Those are all great executive functioning skills of planning, organization, perception, attention, working memory and initiation at work. Well done!????,” one person wrote. “I love this. It really TEACHES instead of just bossing them around. Goes a long way,” another added.” Kelly’s “Notice and Do” list obviously isn’t a fix-all, but the fact that it’s creating awareness around labor which so often goes unnoticed is such a game changer. Think about how different our society might be if this mindset skill was as commonly taught as the alphabet or time tables.Thankfully, Kelly did make it easy to teach kids with a free guide, which you can check out here.

Comedy rock band use 38 songs to prove how 'every pop song' uses the same four chords

Singer-songwriter Ed Sheeran was found not liable on April 4 in a lawsuit where he was accused of stealing elements of the Marvin Gaye classic "Let's Get It On" for his 2014 hit, “Thinking Out Loud."The case called attention to the fact that there are motifs and musical structures common in pop music that no one owns, and all are free to use. When it comes to chord progressions, the 12-bar blues and basic I, IV, V, I progressions you hear in country and folk have been used and reused since people first picked up the guitar. In the wrong hands, the progressions can result in music that is boring and formulaic, but in the right hands, they can be a springboard for fresh ideas.In 2009 Australian comedy group Axis Of Awesome did a funny sketch showing how one four-chord progression, famous for being the basis of Journey’s “Don’t Stop Believing,” has been used countless times by musicians to great effect.They played a medley of 38 major hits using the same progression to prove their point. For musicians, it’s known as the I–V–vi–IV progression, and when played in the key of C it would be C, G, Am, F.Warning: Video contains strong language.Here’s a list of all of the songs in the medley.Journey - “Don't Stop Believing”James Blunt - “You're Beautiful”Alphaville - “Forever Young”Jason Mraz - “I'm Yours”Mika - “Happy Ending”Alex Lloyd - “Amazing”The Calling - “Wherever You Will Go”Elton John - “Can You Feel The Love Tonight”Maroon 5 - “She Will Be Loved”The Last Goodnight - “Pictures Of You”U2 - “With Or Without You”Crowded House - “Fall At Your Feet”Kasey Chambers - “Not Pretty Enough”The Beatles - “Let It Be”Red Hot Chili Peppers - “Under the Bridge”Daryl Braithwaite - “The Horses”Bob Marley - “No Woman No Cry”Marcy Playground - “Sex and Candy”Men at Work - “Land Down Under”Banjo Patterson - “Waltzing Matilda”A-ha - “Take On Me”Green Day - “When I Come Around”Eagle Eye Cherry - “Save Tonight”Toto - “Africa”Beyonce - “If I Were A Boy”The Offspring - “Self Esteem”The Offspring - “You're Gonna Go Far Kid”Pink - “You and Your Hand”Lady Gaga - “Poker Face”Aqua - “Barbie Girl”The Fray - “You Found Me”30h!3 - “Don't Trust Me”MGMT - “Kids”Tim Minchin - “Canvas Bags”Natalie Imbruglia - “Torn”Five For Fighting - “Superman”Axis Of Awesome - “Birdplane”Missy Higgins - “Scar”This article originally appeared last year.
