Our Spacecraft Have Discovered A New Magnetic Process In Space

“As the centuries unfold, millions of artists will live on the moon and paint the moon and Mars as we go out into the universe.”

Today we remember the fourth man to walk on the moon. Astronaut Alan Bean passed away in Houston, at the age of 86.

Bean was the lunar module pilot for Apollo 12 in November 1969, and was commander of Skylab 3 in June 1973. He retired from NASA in 1981 to devote his time to painting.

To celebrate coming back to uni and getting 100 followers (one. hundred. :O ), it’s #optomstudies here with my first ever study tips post! Here’s a step-by-step guide on sleeping and waking up early! Follow me for weekly study tips!

I decided to make this my first topic because this year I’m unfortunately going to have 8am lectures, meaning I’ll need to wake up at 5:30am to get there from my house! And on top of that night time clinic will last until 9:30pm we’re told, meaning I’m going to be getting home at like 11:30pm :( So I’m resetting my body clock to prepare for it :)

The sunrise from this morning’s run :) #nofilter

THE NIGHT BEFORE

Turn off your devices an hour before sleep. The blue light from your computer and mobile can really disrupt the natural melatonin levels that control your sleep cycle, so I always try to end the day with some sort of reading, whether that be for leisure or some summary notes at the end of the day.

Don’t drink any tea or coffee before you sleep. Better to finish the night off with some warm milk and honey (thank you kuroshitsuji) or something similarly soothing. 

Write down a list of what you want to achieve by waking up early. Seeing or even remembering the list can stop you from crawling back to the warmth of your bed, especially in the middle of winter. When the morning you isn’t able to think clearly, let the motivated you make the decisions! And I wouldn’t recommend making a list of what you achieved today to feel accomplished because how’s that going to help you when you’re going to be asleep and unconscious anyway?

Pick out the clothes you want to wear for tomorrow, and make sure they match the weather! Like with the tasks you want to achieve, it’s not a good idea to let the morning you fumble with clothes and what matches well. Definitely do include a jacket or hoodie that you can slip off once the day gets warmer!

Keep your bed reserved for sleeping. Put your smartphone on the other side of the room so that you aren’t tempted to go and check up on your messages on social media. This will reduce the chance that you start a conversation with some night owl friend that ends up continuing past midnight.

Make sure your room is pitch black. This is so that light doesn’t end up disrupting your sleep cycle and so that you condition your body into thinking that it’s time for sleep.

Clear your mind. Whether you achieve this by meditating or otherwise, don’t think about anything, lest you stay up tossing and turning. This includes both exciting events tomorrow and sad events from today. 

Get either 7.5 or 9 hours of sleep. This is because the brain has sleep cycles that are approximately 90 minutes long, so sleeping past will immediately pull you into the next sleep phase. When you wake up in the middle of deep sleep, you end up feeling groggy and tired throughout the whole next morning.

THE NEXT DAY

Reset your sleep cycle by waking at the same time each day. We all have those nights where we absolutely need to finish something by tomorrow (because the professors all conspired with each other and decided to give us double the homework for each subject due the next day :P) but try to keep it constant when you wake. So if you miss the point where you would’ve slept 7.5 hours, go for 6, since you still have a complete sleeping period, and usually that extra hour or so is enough to get the work finished. So don’t think about sleeping in for afternoon classes, because you’ll just feel worse for wear the next time you have morning classes. 

Go cold turkey. Willpower is like a muscle, the more you exercise it the stronger it gets, and I can see no greater struggle than waking up early, jks. I have tried the gradual method of waking up at 7:30, 7:15, 7:00, etc. but I found the best way is to just so straight to your target wake up time. The first day you feel tired in the middle of the day, but it’s easier than adjusting to a new sleep cycle each morning for a week (or longer if you miss a day). 

Wake up with a full blast of natural light. If your bed is next to a window like mine, then pull up the blinds to let as much natural light in as possible to stop the production of melatonin. 

Set an alarm that you know will wake you up. Whether it be a song you like or a super annoying alarm bell, choose something that you can associate with waking up in the morning. For me, I always use BoA’s song Who Are You, because the music video reminds me of a new day, and it has a lovely and soft piano intro :)

Wake up the first time your alarm rings. Although you want to sleep a little longer in order to feel more refreshed, hitting the snooze button is actually detrimental as this explanation from Maimonides Medical Centre explains:

According to Dr. Yizhak Kupfer, Assistant Director of Critical Care and Pulmonary Medicine, using an alarm clock often wakes a person up in the middle of their sleep cycle and cuts rapid eye movement (REM) sleep short. “Over the course of a night, a person goes through five shifting stages of sleep,“ explains Dr. Kupfer. “The brain constantly goes through these stages, emitting different brain waves that reflect if a person is experiencing lighter or deeper periods of sleep.” People who are reliant on their snooze button can diminish the positive effect of a good night’s rest because they are constantly drifting back to sleep only to be abruptly woken up a few minutes later. This causes a shortened, disrupted sleep cycle right before a person starts their day. 

Jump out of bed immediately. Don’t lie in bed thinking; you’ll just drift off again. 

Have a glass of cold water, but don’t just down a whole bottle in one go, because your kidneys are remarkably good at preventing our electrolyte balance from being thrown out of homeostasis, so downing a heap of water will just make them overwork to reduce the water levels. Just see this ELI5 from reddit, though probably with a pinch of salt, considering all the differing opinions. Best to keep that glass of water next to you as you work and drink a few sips at a time while you are working. 

If you drink an excess of water, you have diluted the careful balance of electrolytes. Your kidneys will rapidly dump that water to ensure these electrolyte concentrations are not diluted. 

Put on your clothes quickly! This one comes from personal experience. In the past just to avoid that chilly feel from clothes when winter comes along, I would get out of bed and get my clothes and stuff them under my blanket and take a quick snooze while they got warm. But that usually just ended with me getting my clothes wrinkled rather than actually doing much in terms of warming them up >_< Plus, now I find that doing it quickly is like a burst of energy to get you going for exercise. 

Finish what you were going to do. Remember that list we wrote last night? Do it now and feel great about doing at least one thing extra this morning. 

Don’t have a cup of coffee (yet)! On waking, our bodies stop the production of melatonin and start the production of cortisol to get you going. Cortisol isn’t just for stress, it also starts gluconeogenesis to increase your blood glucose levels (which is important for your brain function) and increases your metabolism. Drinking coffee will disrupt this natural waking hormone, and it also reduces blood flow to the frontal cortex which is responsible for higher order thinking and cognition, explained in this article: 

Caffeine increases energy metabolism throughout the brain but decreases at the same time cerebral blood flow, inducing a relative brain hypoperfusion.

What this means is that although there is more sugar available, oxygen supply decreases. If you do drink coffee, it’s recommended to drink it around 9:00 or so, after the natural cortisol kicks in. I say it’s better to stick to exercise, which is proven to benefit your health in almost every way. 

Exercise. There’s no need for me to explain that this is the best way to feel energized and refreshed for the rest of the day and to get your heart pumping! The morning air is dewy and hasn’t yet been tampered by the smell of car fumes and other pollution, so breath in :) Play some music with beats that will get you moving (this morning’s run brought to you by f(x)’s Rude Love). I snapped a picture as I left the house just before the sun started to rise :)

Enjoy the benefits of a job well done. Give yourself a pat on the back, because it’s tiring to get up at 6am or earlier! You’ve got your study space all to yourself, enjoy it with a cup of orange juice, and some peace and quiet. Get to work/uni/school nice and early, ready to learn something new and feel proud that you aren’t one of those groggy students with their heads glued to the table! 

Hope you’ve enjoyed reading my first study tips post, I intend to publish more and better posts in the future too! Follow me, as I’ll be doing the 100 days of productivity challenge starting March! (this coming week!)

06.04.18 // 🎧: Spring Day - Japanese ver. - BTS

ventured out of my room for once to catch some rays while revising them 🌤 ~

If you are interested in self-studying physics

I found this amazing post that suggests some textbooks and supplemental reading based on big topics, as well as advice on how to structure your studying. A lot of these books, I’ve either used for my physics classes (University Physics by Young and Freedman), will use for future physics classes (Griffiths Electrodynamics and QM books), or are on my reading list (Student’s Guide to Lagrangians and Hamiltonians, Div, Grad, Curl, Feynman Lectures). 

So You Want to Learn Physics - Susan J. Fowler

I found this gem of a blog post while I was looking for ways to review Electrostatics and start reading up on Electrodynamics, Optics, and Relativity (my next physics class). 

There’s also some more reading suggestions in the comments at the bottom, however, feel free to add in if you have any suggestions as well!

Help with learning to love yourself

1. Learn to let go of what happened in the past. You deserve a new start and a fresh beginning. We’ve all messed up and experienced bad things. So don’t allow these memories to rob you of your future. You’re not just a product and a victim of your past. Acknowledge and work through any negative emotions – then put them behind you and start to live again.

2. Work on forgiving yourself. Don’t punish yourself for your past failings or regrets. Instead, see them as a lesson, and a chance to learn and grow. Don’t ridicule, demean or devalue yourself. That was then – this is now … You are different - so move on.

3. Keep a journal where you write down all your thoughts and feelings. When you’re feeling positive, try to savour those emotions and a build a memory trace of all that’s good and positive. When you’re feeling negative try to show some self-compassion, and seek to be gentle and kind to yourself. You need to work on validating and affirming yourself – not being your own enemy and tearing yourself down.

4. Be persistent as you work on accepting yourself. A key part of love is unconditional acceptance. So work on loving who you are right now. Only then will you be able to change some parts of yourself – because you’re able to accept who you are at the core.

5. Trust yourself. You don’t have to please others, or to follow their dictates. Learn to trust your intuition and your own personal judgments.

6. Practice saying “no”. It’s okay to say “no” without feeling guilty. You have the right to decide what you’ll do with your life.

7. Practice receiving and accepting love from others. Know you’re worthy of love – and other people really mean it when they say that you matter, and they love and care for you.

Solar System: 10 Ways Interns Are Exploring Space With Us

Simulating alien worlds, designing spacecraft with origami and using tiny fossils to understand the lives of ancient organisms are all in a day’s work for interns at NASA.

Here’s how interns are taking our missions and science farther.

1. Connecting Satellites in Space

Becca Foust looks as if she’s literally in space – or, at least, on a sci-fi movie set. She’s surrounded by black, except for the brilliant white comet model suspended behind her. Beneath the socks she donned just for this purpose, the black floor reflects the scene like perfectly still water across a lake as she describes what happens here: “We have five spacecraft simulators that ‘fly’ in a specially designed flat-floor facility,” she says. “The spacecraft simulators use air bearings to lift the robots off the floor, kind of like a reverse air hockey table. The top part of the spacecraft simulators can move up and down and rotate all around in a similar way to real satellites.” It’s here, in this test bed on the Caltech campus, that Foust is testing an algorithm she’s developing to autonomously assemble and disassemble satellites in space. “I like to call it space K’nex, like the toys. We’re using a bunch of component satellites and trying to figure out how to bring all of the pieces together and make them fit together in orbit,” she says. A NASA Space Technology Research Fellow, who splits her time between Caltech and NASA’s Jet Propulsion Laboratory (JPL), working with Soon-Jo Chung and Fred Hadaegh, respectively, Foust is currently earning her Ph.D. at the University of Illinois at Urbana-Champaign. She says of her fellowship, “I hope my research leads to smarter, more efficient satellite systems for in-space construction and assembly.”

2. Diving Deep on the Science of Alien Oceans

Three years ago, math and science were just subjects Kathy Vega taught her students as part of Teach for America. Vega, whose family emigrated from El Salvador, was the first in her family to go to college. She had always been interested in space and even dreamed about being an astronaut one day, but earned a degree in political science so she could get involved in issues affecting her community. But between teaching and encouraging her family to go into science, It was only a matter of time before she realized just how much she wanted to be in the STEM world herself. Now an intern at NASA JPL and in the middle of earning a second degree, this time in engineering physics, Vega is working on an experiment that will help scientists search for life beyond Earth. 

“My project is setting up an experiment to simulate possible ocean compositions that would exist on other worlds,” says Vega. Jupiter’s moon Europa and Saturn’s moon Enceladus, for example, are key targets in the search for life beyond Earth because they show evidence of global oceans and geologic activity. Those factors could allow life to thrive. JPL is already building a spacecraft designed to orbit Europa and planning for another to land on the icy moon’s surface. “Eventually, [this experiment] will help us prepare for the development of landers to go to Europa, Enceladus and another one of Saturn’s moons, Titan, to collect seismic measurements that we can compare to our simulated ones,” says Vega. “I feel as though I’m laying the foundation for these missions.”

3. Unfolding Views on Planets Beyond Our Solar System

“Origami is going to space now? This is amazing!” Chris Esquer-Rosas had been folding – and unfolding – origami since the fourth grade, carefully measuring the intricate patterns and angles produced by the folds and then creating new forms from what he’d learned. “Origami involves a lot of math. A lot of people don’t realize that. But what actually goes into it is lots of geometric shapes and angles that you have to account for,” says Esquer-Rosas. Until three years ago, the computer engineering student at San Bernardino College had no idea that his origami hobby would turn into an internship opportunity at NASA JPL. That is, until his long-time friend, fellow origami artist and JPL intern Robert Salazar connected him with the Starshade project. Starshade has been proposed as a way to suppress starlight that would otherwise drown out the light from planets outside our solar system so we can characterize them and even find out if they’re likely to support life. Making that happen requires some heavy origami – unfurling a precisely-designed, sunflower-shaped structure the size of a baseball diamond from a package about half the size of a pitcher’s mound. It’s Esquer-Rosas’ project this summer to make sure Starshade’s “petals” unfurl without a hitch. Says Esquer-Rosas, “[The interns] are on the front lines of testing out the hardware and making sure everything works. I feel as though we’re contributing a lot to how this thing is eventually going to deploy in space.”

4. Making Leaps in Extreme Robotics

Wheeled rovers may be the norm on Mars, but Sawyer Elliott thinks a different kind of rolling robot could be the Red Planet explorer of the future. This is Elliott’s second year as a fellow at NASA JPL, researching the use of a cube-shaped robot for maneuvering around extreme environments, like rocky slopes on Mars or places with very little gravity, like asteroids. A graduate student in aerospace engineering at Cornell University, Elliott spent his last stint at JPL developing and testing the feasibility of such a rover. “I started off working solely on the rover and looking at can we make this work in a real-world environment with actual gravity,” says Elliott. “It turns out we could.” So this summer, he’s been improving the controls that get it rolling or even hopping on command. In the future, Elliott hopes to keep his research rolling along as a fellow at JPL or another NASA center. “I’m only getting more and more interested as I go, so I guess that’s a good sign,” he says.

5. Starting from the Ground Up

Before the countdown to launch or the assembling of parts or the gathering of mission scientists and engineers, there are people like Joshua Gaston who are helping turn what’s little more than an idea into something more. As an intern with NASA JPL’s project formulation team, Gaston is helping pave the way for a mission concept that aims to send dozens of tiny satellites, called CubeSats, beyond Earth’s gravity to other bodies in the solar system. “This is sort of like step one,” says Gaston. “We have this idea and we need to figure out how to make it happen.” Gaston’s role is to analyze whether various CubeSat models can be outfitted with the needed science instruments and still make weight. Mass is an important consideration in mission planning because it affects everything from the cost to the launch vehicle to the ability to launch at all. Gaston, an aerospace engineering student at Tuskegee University, says of his project, “It seems like a small role, but at the same time, it’s kind of big. If you don’t know where things are going to go on your spacecraft or you don’t know how the spacecraft is going to look, it’s hard to even get the proposal selected.”

6. Finding Life on the Rocks

By putting tiny samples of fossils barely visible to the human eye through a chemical process, a team of NASA JPL scientists is revealing details about organisms that left their mark on Earth billions of years ago. Now, they have set their sights on studying the first samples returned from Mars in the future. But searching for signatures of life in such a rare and limited resource means the team will have to get the most science they can out of the smallest sample possible. That’s where Amanda Allen, an intern working with the team in JPL’s Astrobiogeochemistry, or abcLab, comes in. “Using the current, state-of-the-art method, you need a sample that’s 10 times larger than we’re aiming for,” says Allen, an Earth science undergraduate at the University of California, San Diego, who is doing her fifth internship at JPL. “I’m trying to get a different method to work.” Allen, who was involved in theater and costume design before deciding to pursue Earth science, says her “superpower” has always been her ability to find things. “If there’s something cool to find on Mars related to astrobiology, I think I can help with that,” she says.

7. Taking Space Flight Farther

If everything goes as planned and a thruster like the one Camille V. Yoke is working on eventually helps send astronauts to Mars, she’ll probably be first in line to play the Mark Watney role. “I’m a fan of the Mark Watney style of life [in “The Martian”], where you’re stranded on a planet somewhere and the only thing between you and death is your own ability to work through problems and engineer things on a shoestring,” says Yoke. A physics major at the University of South Carolina, Yoke is interning with a team that’s developing a next-generation electric thruster designed to accelerate spacecraft more efficiently through the solar system. “Today there was a brief period in which I knew something that nobody else on the planet knew – for 20 minutes before I went and told my boss,” says Yoke. “You feel like you’re contributing when you know that you have discovered something new.”

8. Searching for Life Beyond Our Solar System

Without the option to travel thousands or even tens of light-years from Earth in a single lifetime, scientists hoping to discover signs of life on planets outside our solar system, called exoplanets, are instead creating their own right here on Earth. This is Tre’Shunda James’ second summer simulating alien worlds as an intern at NASA JPL. Using an algorithm developed by her mentor, Renyu Hu, James makes small changes to the atmospheric makeup of theoretical worlds and analyzes whether the combination creates a habitable environment. “This model is a theoretical basis that we can apply to many exoplanets that are discovered,” says James, a chemistry and physics major at Occidental College in Los Angeles. “In that way, it’s really pushing the field forward in terms of finding out if life could exist on these planets.” James, who recently became a first-time co-author on a scientific paper about the team’s findings, says she feels as though she’s contributing to furthering the search for life beyond Earth while also bringing diversity to her field. “I feel like just being here, exploring this field, is pushing the boundaries, and I’m excited about that.”

9. Spinning Up a Mars Helicopter

Chloeleen Mena’s role on the Mars Helicopter project may be small, but so is the helicopter designed to make the first flight on the Red Planet. Mena, an electrical engineering student at Embry-Riddle Aeronautical University, started her NASA JPL internship just days after NASA announced that the helicopter, which had been in development at JPL for nearly five years, would be going to the Red Planet aboard the Mars 2020 rover. This summer, Mena is helping test a part needed to deploy the helicopter from the rover once it lands on Mars, as well as writing procedures for future tests. “Even though my tasks are relatively small, it’s part of a bigger whole,” she says.

10. Preparing to See the Unseen on Jupiter’s Moon Europa

In the 2020s, we’re planning to send a spacecraft to the next frontier in the search for life beyond Earth: Jupiter’s moon Europa. Swathed in ice that’s intersected by deep reddish gashes, Europa has unveiled intriguing clues about what might lie beneath its surface – including a global ocean that could be hospitable to life. Knowing for sure hinges on a radar instrument that will fly aboard the Europa Clipper orbiter to peer below the ice with a sort of X-ray vision and scout locations to set down a potential future lander. To make sure everything works as planned, NASA JPL intern Zachary Luppen is creating software to test key components of the radar instrument. “Whatever we need to do to make sure it operates perfectly during the mission,” says Luppen. In addition to helping things run smoothly, the astronomy and physics major says he hopes to play a role in answering one of humanity’s biggest questions. “Contributing to the mission is great in itself,” says Luppen. “But also just trying to make as many people aware as possible that this science is going on, that it’s worth doing and worth finding out, especially if we were to eventually find life on Europa. That changes humanity forever!”
