Cascading Loops On The Surface Of The Sun Highlight An Active Region That Had Just Rotated Into View

Cascading loops on the surface of the sun highlight an active region that had just rotated into view of our solar-observing spacecraft. We have observed this phenomenon numerous times, but this one was one of the longest and clearest sequences we have seen in years. 

The bright loops are actually charged particles spinning along the magnetic field lines! The action was captured in a combination of two wavelengths of extreme ultraviolet light over a period of about 20 hours.

NASA Spotlight: Astronaut Candidate Frank Rubio

NASA Spotlight: Astronaut Candidate Frank Rubio

“Where else in the world would you hear a story like mine? I’m a kid from a single mom, a teenage mom from El Salvador who worked in all sorts of low-income jobs... My story is a great story about America. What are the chances that a kid like me would end up being where I am today?” - Frank Rubio

Dr. Frank Rubio is a Los Angeles-born Salvadorian-American who was selected as NASA astronaut candidate in 2017. The Florida native graduated from the U.S. Military Academy and earned a Doctorate of Medicine from the Uniformed Services University of the Health Sciences. Prior to attending medical school, he served as a UH-60 Blackhawk helicopter pilot and flew more than 1,100 hours, including more than 600 hours of combat and imminent danger time during deployments to Bosnia, Afghanistan and Iraq. Dr. Rubio is a board certified family physician and flight surgeon. At the time of his selection, he was serving in the 10th Special Forces Group (Airborne). 

Frank took time from training to become a certified NASA Astronaut to answer questions about his life and career: 

You’ve served in the Special Forces, are certified as a family physician and now are a selected Astronaut candidate – What inspired you to apply to be an astronaut and how do you think your past jobs will play a role in your new career?

It was a friend in the astronaut corps that recommended I put in an application. After he recommended it, I thought it was an amazing opportunity to be a part of something bigger than myself and to allow me to continue to serve. It gave me an opportunity to explore and make a difference. And it sounded like a lot of fun! My past careers have allowed me to be comfortable with uncertainty and the unknown and to function well despite often not having all the facts.

Do you have any secret skills, talents, or hobbies?

I was on the skydive team in college.

image

How would you describe your job to a five year old?

I have one of the best jobs in the world because I get to train and work towards a mission that helps humankind. My job is unique in that you and your team are working to make a difference from a much bigger perspective. And hopefully I get to ride on a rocket and go to space!

image

What is the best advice you’ve ever received?

Early in my career and throughout my career I was assigned to jobs that may not have been my first choice, but they turned out to be amazing opportunities. I was taught to have a good attitude and give it your best no matter where you are. Those opportunities ended up being some of the best and helped me get where I am today.

Any facts about/aspects of astronaut training that you think people would be surprised to find out?

A lot of people don’t realize how much studying is involved. It’s comparable to the studying I did in flight school or medical school.

What are five things that you will definitely take with you on your first space flight?

Pictures of my family and friends, a Bible and lots of books to read (probably on a tablet), patches from my Army units- they helped form me to be the person I am today, music, and if I could take my dog (and family), I definitely would! Also, Something for each of my kids to give to them.

You just finished up geology training. What fact or skill did you learn during geology training that you think rocks the most?

The overall idea that the rocks and the different units we studied have so much to tell. You learn to appreciate how much the layout of the land and the rocks and the way they interact together can tell you about the history of that place. It’s amazing.

image

Since you’re getting close to completing astronaut training, what about your first space flight are you most looking forward to?

Everything will be fantastic from the ride up there, to floating in space, to the amazing science we get to perform, to being part of the team. I don’t think I’ll ever get tired of looking back at Earth and having the chance to get the perspective to recognize the grandeur and uniqueness of Earth.

What would be the first thing you would say if you happened to make contact with an alien lifeform able to communicate with you?

Hello! How are you? I would want to know about them and to share humankind with them.

Thank you for your time Frank, and good luck as you continue to complete astronaut training!

Solar System: Things to Know This Week

Earth is the ultimate ocean planet (that we know of), but it turns out that our solar system has water in some surprising places, with five ocean-bearing moons and potentially several more worlds with their own oceans. 

image

1. The Original "Alien Ocean"

Our Galileo spacecraft (1989-2003) detected the first evidence of an ocean beyond Earth under the ice of Jupiter's icy moon Europa.

image

2. Lost Oceans

There are signs that Mars and Venus once had oceans, but something catastrophic may have wiped them out. Earth's natural force field -- our magnetosphere -- acts like shield against the erosive force of the solar wind.

image

3. Earth, the Original Ocean World

The search for life beyond Earth relies, in large part, on understanding our home planet. Among the newest Earth ocean explorers us the Cyclone Global Navigation Satellite System, or CYGNSS--a constellation of microsatellites that will make detailed measurements of wind speeds over Earth's oceans to help understand hurricanes. The spacecraft have moved into their science operations phase.

image

4. Sister Ships

It's fitting the first mission to explore an alien ocean is named in honor of fast-sailing clipper ships of old. Our Europa Clipper spacecraft will seek signs of habitability on Jupiter's moon Europa.

image

5. Game Changer

Scientists expected Saturn's moon Enceladus to be a tiny, solid chunk of ice and rock. But, not long after arriving at Saturn, our Cassini spacecraft made a series of incremental discoveries, eventually confirming that a global subsurface ocean is venting into space, with signs of hydrothermal activity.

image

6. Why Ocean Worlds Matter

"The question of whether or not life exists beyond Earth, the question of whether or not biology works beyond our home planet, is one of humanity's oldest and yet unanswered questions. And for the first time in the history of humanity, we have the tools and technology and capability to potentially answer this question. And, we know where to go to find it. Jupiter's ocean world Europa." - Kevin Hand, NASA Astrobiologist

image

7. More Alien Oceans

Scientists think Jupiter's giant moons Ganymede and Callisto also hide oceans beneath their surfaces. Elsewhere in the solar system, scientists hope to look for hidden oceans on far-flung worlds from Ceres in the main asteroid belt to Pluto in the Kuiper Belt.

image

8. Cold Faithful(s)?

Thanks to our Cassini orbiter we know the tiny moon Enceladus is venting its ocean into space in a towering, beautiful plume. The Hubble Space Telescope also has seen tantalizing hints of plumes on Jupiter's moon Europa. Plumes are useful because they provide samples of ocean chemistry for oceans that could be miles below the surface and difficult for spacecraft to reach. It's like they're giving out free samples!

image

9. Titanic Seas and Ocean

Saturn's moon Titan not only has liquid hydrocarbon seas on its surface. It also shows signs of a global, subsurface saltwater ocean--making the giant moon a place to possibly look for life as we know it and life as we don't know it ... yet.

image

10. Oceans Beyond

Several of the thousands of planets discovered beyond our solar system orbit their stars in zones where liquid surface water is possible--including Proxima-b, a rocky planet orbiting the star nearest to our own.

BONUS: Adopt a bit of YOUR Ocean World

We invite everyone to help us celebrate Earth Day 2017 by virtually adopting a piece of Earth as seen from space. Your personalized adoption certificate will feature data from our Earth-observing satellites for a randomly assigned location, much of it ocean (it is 70 percent of the Earth's surface after all!). Print it and share it, then explore other locations with our interactive map and get even more Earth science data from NASA's Worldview website.

Visit go.nasa.gov/adopt to adopt your piece of the planet today!

Are You Ready to #BeTheSpark?

Students - want to modify a NASA Spinoff technology and solve a real word problem?

image

Our Optimus Prime Spinoff Promotion and Research Challenge, known as OPSPARC for short, is a student challenge that guides teams through various NASA Spinoff technologies that are in their everyday world. The teams use their imagination, creativity, and engineering skills to develop their own ideas for NASA spinoff technology.

image

Spinoffs are technologies originally created for space and modified into everyday products used here on Earth.

image

Perhaps the most widely recognized NASA spinoff, memory foam was invented by NASA-funded researchers looking for ways to keep test pilots cushioned during flights. Today, memory foam makes for more comfortable beds, couches and chairs, not to mention better shoes, movie theater seats and even football helmets.

There are more than two-thousand NASA Spinoffs They include memory foam, invisible braces, firefighting equipment, programmable pace makers, artificial limbs, scratch-resistant lenses, aircraft anti-icing systems, endangered species tracking software, cochlear implants, satellite television, long-distance telecommunications, and many, many more.

image

The deadline has been extended to February 26th for our Mission 3 student challenge. Sign up NOW here: https://opsparc.gsfc.nasa.gov/

Fans of the Hasbro TRANSFORMERS brand will pick up on the play on words between the challenge name, OPSPARC, and the "AllSpark" from the TRANSFORMERS universe. The AllSpark is what gave the TRANSFORMERS robots life and knowledge, which they use to help mankind — just like NASA spinoffs. Students from around the globe will have the opportunity to Be The Spark!

Next Gen @ NASA: Celebrating National Intern Day

To celebrate National Intern Day, we asked interns to share how they got their internship and their perspective and advice to the next generation of prospective NASA interns.

Meet our interns and check out their suggestions for the next generation.

Sarah Kilpatrick, STDCE-2 Data Intern

Sarah is a summer Surface Tension Driven Convection Experiment Data Intern at NASA. Her inspiration for applying for an internship came from a passion for science from an early age. “I grew up in a family that liked, enjoyed and appreciated science and the fun of it all,” she recalls. “I grew up watching PBS, NOVA, and other science shows, so when I saw NASA had opportunities for students like me, I was very interested.” 

Sarah’s advice to the next generation of NASA interns is one of perseverance and resilience.

Nicholas Natsoulas, Attitude Control Engineering Intern

Nicholas is a summer Attitude Control Engineering Intern at NASA. He wants to contribute to scientific innovation and discovery. “Overall, what inspired me to apply and come to work here was to contribute to the scientific exploration of space while learning about unique perspectives and innovative space discoveries.”

Nicholas’s advice for prospective NASA interns is to make the most out of your time here and to be a curious and eager learner.

“Use all the resources that are at your center and ask questions about projects you are working on. Don’t be afraid to talk to your mentor about your plans for the future and ask for any advice you may need, as they are more than willing to help you during your time here,” says Nicholas.

One man standing at an office desk pointing at laptop screen and one man sitting on chair working from laptop.

Nicholas and his mentor, Brent Faller, are using software to inform design decisions on a variety of spacecraft.

Nylana Murphy, former Additive Manufacturing Engineering Intern

As an American Indian College Fund ambassador and a Navajo engineer, Nylana Murphy hopes her internship story will inspire others to pursue a career in aerospace.

After attending the American Indian Science Engineering Society Conference, Nylana secured an internship in the additive manufacturing research laboratory at NASA Marshall.

 “My internships have helped me get to where I am,” she says, “There is a career for everyone, where their dreams can become reality. Those dreams WILL become a reality.”

A Navajo woman sits with her hands clasped on her lap. She is wearing a black t-shirt with a NASA logo and a turquoise ring and bracelet.

You might be wondering: what happens after a NASA internship Here’s what two of our former interns did.

Loral O’Hara, Astronaut, former intern

Lorel interned at NASA JPL in 2003, and at NASA Goddard in 2004. She earned science degrees from both the University of Kansas and Purdue University.

As a research and project engineer, O’Hara reported for duty in August 2017 and completed two years of training as an Astronaut Candidate. She is projected to fly in Soyuz missions as a NASA astronaut soon.

If she could go back in time, Loral says she would tell her younger self to enjoy the opportunities that come her way—and never stop looking for new ones. “Enjoy the whole journey of…figuring out what it is that you like to do and exploring all different kinds of things.”

A woman is in a pool with a helmet and other protective gear on.

Jeff Carlson, Assembly, Test, Launch Operations Engineer

The “7 Minutes of Terror” video piqued Jeff Carlson’s interest in working at JPL. He thought, "That's the coolest thing I've ever heard of. I've got to go be a part of that in some way." While interning at the Jet Propulsion Laboratory, he worked on Starshade, a sunflower-shaped device used to block starlight in order to reveal planets orbiting a star. Later, he went on to work on the team tasked with assembling and testing the “head” and “neck” (officially called the Remote Sensing Mast) for the Mars 2020 rover.

A man stands next to a testbed version of the Mars 2020 rover. His hair is pulled back in a ponytail and he is wearing a white lab coat and gloves.

Boo-tiful Ring Galaxies

image

A ghoulish secret lurks within each of these gorgeous galaxies. Their rings are dotted with stellar graveyards!

image

These objects are called ring galaxies, and scientists think most of them form in monster-sized crashes. Not just any galaxy collision will do the trick, though. To produce the treat of a ring, a smaller galaxy needs to ram through the center of a larger galaxy at just the perfect angle.

image

The collision causes ripples that disturb both galaxies. The gravitational shock causes dust, gas, and stars in the larger galaxy’s disk to rush outward. As this ring of material plows out from the galaxy’s center, gas clouds collide and trigger the birth of new stars.

image

In visible light, the blue areas in the galaxies’ rings show us where young, hot stars are growing up. Faint, pink regions around the ring mark stellar nurseries where even younger stars set hydrogen gas aglow.

The newborn stars come in a mix of sizes, from smaller ones like our Sun all the way up to huge stars with tens of times the Sun’s mass. And those massive stars live large!

While a star like our Sun will last many billions of years before running out of fuel, larger stars burn much brighter and faster. After just a few million years, the largest stars explode as supernovae. When massive stars die, they leave behind a stellar corpse, either a neutron star or black hole.

image

When we turn our X-ray telescopes to these ring galaxies, we see telltale signs of stellar remnants dotted throughout their ghostly circles. The purple dots in the X-ray image above are neutron stars or black holes that are siphoning off gas from a companion star, like a vampire. The gas reinvigorates stellar corpses, which heat up and emit X-rays. These gas-thirsty remains are beacons lighting the way to stellar graveyards.

Spiral galaxies — like our home galaxy, the Milky Way — have curved arms that appear to sweep out around a bright center. The dust and gas in those spiral arms press together, causing cycles of star formation that result in a more even mix of new stars and stellar corpses scattered throughout our galaxy. No creepy ring of stellar corpses here!

Up For Some Virtual Cloud Watching? ☁️

Up for some virtual cloud watching? ☁️

What do you see in Jupiter's hazy atmosphere?

Our NASA JunoCam mission captured this look at the planet’s thunderous northern region during the spacecraft’s close approach to the planet on Feb. 17, 2020.

Some notable features in this view are the long, thin bands that run through the center of the image from top to bottom. Juno has observed these long streaks since its first close pass by Jupiter in 2016.
