St. Patrick’s Aurora Illuminates the Night Sky

The green lights of an aurora dramatically explode outward against the backdrop of the night sky peppered with fluffy white clouds and pinprick stars. A hint of red is also visible in the center of the light. Pine trees cast in shadow are seen below.

This majestic image of the dazzling green lights of the aurora borealis was captured on March 17, 2015, around 5:30 a.m. EDT in Donnelly Creek, Alaska.

The aurora borealis and aurora australis, often called the northern lights and southern lights, are common occurrences at high northern and southern latitudes, less frequent at mid-latitudes, and seldom seen near the equator.

These colorful ribbons of light are the visible manifestation of the solar wind – the flow of charged particles from the Sun – interacting with the Earth’s magnetosphere. Strong geomagnetic storms stimulate our atmosphere and light up the night sky, creating auroras.

NASA Announces Semifinalists of Power to Explore Challenge

NASA Announces Semifinalists of Power to Explore Challenge

NASA selected 45 student essays as semifinalists of its 2024 Power to Explore Challenge, a national competition for K-12 students featuring the enabling power of radioisotopes. Contestants were challenged to explore how NASA has powered some of its most famous science missions and to dream up how their personal “superpower” would energize their success on their own radioisotope-powered science mission. The competition asked students to learn about Radioisotope Power Systems (RPS), “nuclear batteries” that NASA uses to explore the harshest, darkest, and dustiest parts of our solar system. RPS have enabled many spacecraft to conduct otherwise impossible missions in total darkness.

In 250 words or less, students wrote about a mission of their own that would use these space power systems and described their own power to achieve their mission goals. The challenges of space exploration without solar power are especially relevant ahead of the United States’ upcoming April 8 total solar eclipse, which will offer a momentary glimpse into what life would be like without sunlight.

The Power to Explore Challenge offered students the opportunity to learn more about these reliable power systems, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest received 1,787 submitted entries from 48 states and Puerto Rico.

“It has been so exciting to see how many students across the nation have submitted essays to NASA’s Power to Explore Challenge,” said Carl Sandifer, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland. “We have been thrilled to read their creative RPS-powered mission concepts and have been inspired learning about their many ‘superpowers’ that make them the bright future of NASA – the Artemis Generation.”

Entries were split into three categories: grades K-4, 5-8, and 9-12. Every student who submitted an entry received a digital certificate, and over 4,094 participants who signed up received an invitation to the Power Up virtual event. With NASA’s Associate Administrator for the Science Mission Directorate Nicola Fox, NASA’s Radioisotope Power Systems Program Manager Carl Sandifer, and Kim Rink of NASA’s Jet Propulsion Laboratory in

We have been thrilled to read their creative RPS-powered mission concepts and have been inspired learning about their many ‘superpowers’ that make them the bright future of NASA – the Artemis Generation.

Crew Ends Week Closing Out Health Investigations and Completing Training

Crew Ends Week Closing Out Health Investigations and Completing Training

NASA astronaut and Expedition 70 Flight Engineer Jeanette Epps is pictured floating in microgravity aboard the International Space Station.

The seven International Space Station residents are moving into an off-duty weekend following a busy week of crew departures, health investigations, and spacesuit operations. The Expedition 70 crew spent Friday wrapping up procedures that began earlier in the week and completing some SpaceX Dragon training.

Yesterday, first-time station resident Jeanette Epps processed blood samples for the Immunity Assay investigation. The NASA Flight Engineer continued that work into Friday to monitor how spaceflight impacts cellular immune function. After lunch, Epps carried out an experiment to test the efficiency of an antimicrobial coating in space before completing some crew orientation activities as she continues to adjust to living and working in low Earth orbit.

Following yesterday’s set up of the Cerebral Autoregulation investigation, Flight Engineer Matthew Dominick measured blood flow in the brain using non-invasive methods to provide researchers insights on how the brain regulates its blood supply in microgravity. For this specific investigation, Dominick used the Cardiolab Portable Doppler, an instrument that measures blood flow velocity to the brain and blood pressure waveforms in the arteries.

The NASA resident then configured the Sleep in Orbit device, which examines the physiological differences between sleep on Earth and in space. The microgravity environment can affect the daily rhythm and sleep patterns of astronauts. Research from Sleep in Orbit could guide the development of measures that mitigate poor sleep and its effects on astronauts as missions stretch further.

Flight Engineers Michael Barratt and Loral O’Hara of NASA both completed a round of SpaceX Dragon rendezvous and docking training on Friday. O’Hara also conducted some maintenance on the BioFabrication Facility and stowed tools she used earlier in the week while configuring spacesuits. Barratt spent the rest of his day inspecting equipment that would be used in the unlikely event an emergency were to occur on station.

In the Roscosmos segment, Commander Oleg Kononenko and Flight Engineers Alexander Grebenkin and Nikolai Chub spent the morning conducting a weekly conference with ground teams. Afterward, Grebenkin replaced some condensate pump lines while Kononenko and Chub teamed up once more to complete another round of eye exams.

In honor of Women’s History Month, we recently sat down with Sarah Mann, public affairs specialist and member of the Women’s Networking Group (WNG) at NASA’s Armstrong Flight Research Center in Edwards, California, to learn more about her role and working at NASA.

What do you do at NASA and how do you help support Armstrong’s mission?

I get to tell the story about the exciting developments that happen with various programs and projects happening at NASA’s primary center for high-risk, atmospheric flight research. In writing for web and social, working with media, my job informs the public on the status and successes of programs and projects.

Why did you choose to work at NASA and how long have you worked here?

Who wouldn’t want to work for NASA?! I have been working for NASA for just over three years – and I have loved every minute! Growing up in “Aerospace Valley” it feels natural to work for NASA, and especially at Armstrong, where NASA develops the most cutting-edge technology for the first “A” in NASA.

What has been your proudest accomplishment or highlight of your career?

Before I worked for NASA, I did public relations for a local charter school that focused on STEM education; within my first week working for this school, it was decided to build a brand-new school and public outreach was a major component of the project. It was incredible to be a part of something from the very beginning; community outreach meetings to the groundbreaking ceremony, beam signing, getting the certificate of occupancy, to finally the grand opening of a brand-new school. I don’t think I will ever forget during the ribbon cutting ceremony and looking around to see so many students, families, and the community and thinking how far we had come from those initial conversations to now walking into the front door of a beautiful new school.

What is one piece of advice you’ve never forgotten?

My favorite professor in undergrad told us to keep our textbooks. Hardcover textbooks may be a thing of the past, but for me, they are still valuable reference tools, idea generators, reminders, and in some ways just a way to reminisce about the good old college days.

Do you have any advice for others like yourself who may be contemplating a career at NASA?

Network! Apply! Throughout my career, I have found that networking has been important for my career goals. Also, apply to all possible jobs – even those positions that are a little bit of a stretch for your experience. But with every interview you learn more and more and it helps prepare for future positions.

What is the most exciting aspect of your job?

It is really hard to identify just one exciting aspect of my job. Every day I get to work with the best people in their field and I get to tell the story about what they are working on to move the NASA mission forward.

What did you want to be when you were growing up? Did you think you would ever work for NASA?

Growing up I really thought I was going to be a professional ballet dancer, however, physically that wasn’t going to be possible, so I had to pivot. Thinking that being a lawyer would be very cool so I could afford to have a BMWZ8 – but I really wasn’t passionate about law. While in high school I took a lot of advanced science classes (chemistry and physics) but being in a lab all day wasn’t really appealing to me either. Then my senior year of high school, I learned about public affairs, and the rest is history. Never did I think I would work for NASA, an aerospace company probably, but NASA – it was such an exciting day when I got the call being offered a position to work for NASA.

What’s the strangest tradition in your family? Or a unique family tradition?

We all sit in the same exact spots in my parents’ house on Christmas morning to open gifts. It started when we were very little and still happens today – we also take turns opening gifts.

If you could master a skill without any work, what would it be?

Being a nuclear engineer would be so cool, so all the skills that would come with that job!

GLOBE Eclipse Challenge: Clouds and Our Solar-Powered Earth

A stylized drawing shows Earth covered with clouds. To the right is an eclipsed Sun as it would appear from Earth’s surface. The text “GLOBE Eclipse” appears at the top of the image.
The GLOBE Program invites you to participate in the natural experiment provided by April 8’s total solar eclipse by recording changes in cloud conditions and in temperature everywhere (both inside and outside the eclipse path).
Heather Mortimer, GLOBE Observer/NASA Goddard Space Flight Center

Imagine standing outside on a cool spring day when all at once, the clouds shift and sunlight streams down, bathing you with warmth. In moments like this, you might notice – and appreciate – the Sun just a little bit more, but you feel the Sun’s influence every day, even when you don’t feel the Sun itself. Solar energy drives the water cycle and cloud formation. It fuels winds and nourishes growing plants. The Sun is intricately connected to the rhythm of life on Earth because we live on a solar-powered planet.

So what happens on Earth when the Sun is blocked during an eclipse? How cold will it get in the Moon’s shadow? What will happen to the clouds? Will the temperature change? Will winds shift? To answer these questions, The GLOBE Program invites you to participate in the natural experiment provided by April 8’s total solar eclipse by recording changes in cloud conditions and in temperature everywhere (both inside and outside the eclipse path).

Left, a screenshot shows the GLOBE Observer app home screen including a button for recording eclipse observations. It also includes buttons for clouds, mosquito habitats, land cover, and trees. Right, a line graph shows a 15-degree-Celsius drop in temperature during the annular eclipse on October 14, 2023. The temperature rises again after the eclipse. Bars under the line graph indicate a decrease in cloud cover with clouds entirely dissipating immediately after the minimum temperature point.
Volunteers measuring changes in temperature and clouds with GLOBE Observer saw a drop in air temperature. Some volunteers also saw puffy (cumulus) clouds dissipate or collapse and flatten out.
The GLOBE Program

To participate in GLOBE Eclipse:

  • Download the free GLOBE Observer app and register with an active email address.
  • Get an air temperature thermometer so you are ready to record the temperature during the eclipse.
  • Begin observing clouds now (before eclipse day) so that you are comfortable with the process. To get ready, we encourage you to participate in the GLOBE Eclipse Challenge: Clouds and Our Solar-Powered Earth, March 15-April 15. During the challenge, you will record cloud conditions at varying times during the day.
  • On April 8, tap on “Eclipse” in the GLOBE Observer app and start recording your temperature and sky conditions before, during, and after the eclipse. You will measure temperature every 5-10 minutes and clouds every 15-30 minutes or whenever you see change. You can explore the Eclipse protocol in the app without entering data (practice mode) starting in mid-March. You can start entering actual temperature data the week before the eclipse.
Participating in GLOBE Eclipse as a volunteer requires the GLOBE Observer app and a thermometer. Training is provided in the app. No prior experience is necessary.

You can find videos and additional training resources at: https://observer.globe.gov/eclipse.

The GLOBE Program is an international science and education program that engages students and volunteers from around the globe in monitoring the environment in support of Earth system science. Through GLOBE Observer, the app of The GLOBE Program, volunteers document clouds every day, creating a years-long record of change across seasons. The GLOBE Eclipse tool with the app extends routine cloud observations to provide insight into what happens in the sky when the Sun is blocked.
