“I Felt I Was An Accepted Team Member. It Was A Great Experience And A Unique Opportunity.”

ICYMI: New sounds from Mars dropped! Turn the volume up to hear our Ingenuity Mars Helicopter flying on the Red Planet.

Captured by our Perseverance Mars Rover, this is the first time a spacecraft on another planet has recorded the sounds of a separate spacecraft. In this audio track, Perseverance used its SuperCam microphone to listen to the Ingenuity helicopter on April 30, 2021 as it flew on Mars for the fourth time.

With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the mission wasn’t sure if the microphone would pick up any sound of the flight. Even during flight when the helicopter’s blades are spinning at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds.

Say Hello to NGC 6441

Location: In the Scorpius constellation

Distance from Earth: About 44,000 light-years

Object type: Globular star cluster

Discovered by: James Dunlop in 1826

Each tiny point of light in this image is its own star - and there are more than a million of them! This stunning image captured by the Hubble Telescope depicts NGC 6441, a globular cluster that weighs about 1.6 million times the mass of our Sun. Globular clusters like NGC 6441 are groups of old stars held together by their mutual gravitational attraction, appearing nearly spherical in shape due to the density of stars that comprises them. This particular cluster is one of the most massive and luminous in our Milky Way Galaxy. It is also home to a planetary nebula and four pulsars (rotating neutron stars that emit beams of radiation at steady intervals, detected when the beams are aimed at Earth). 

Read more information about NGC 6441 here.

Right now, the Hubble Space Telescope is delving into its #StarrySights campaign! Find more star cluster content and spectacular new images by following along on Hubble’s Twitter, Facebook, and Instagram.

“I realized, really for the first time, that people who didn’t even know me were wishing for my success —  hoping to share in the pride of future accomplishments, but even more important, willing to provide encouragement in the face of disappointments. I hope that by sharing my experiences, others will be inspired to set high goals for themselves.”

- Ellen Ochoa is the first Hispanic director of NASA’s Johnson Space Center and the first Hispanic woman to go to space.

Q: You were the first Hispanic woman to go to space, and you’re the first Hispanic director of the Johnson Space Center. What does the achievement of firsts like these mean to you? What kind of responsibility comes with paving the way?

Becoming an astronaut was a personal goal for me, so I was surprised and overwhelmed to receive such warm support from the entire Hispanic community when I was selected for the astronaut corps. I realized, really for the first time, that people who didn’t even know me were wishing for my success —  hoping to share in the pride of future accomplishments, but even more important, willing to provide encouragement in the face of disappointments. In the same way, in addition to working hard to do my best at every position I’ve had, it became an important part of my job to provide encouragement to others, particularly women and minorities underrepresented in STEM [Science Technology Engineering and Math] fields. I hope that by sharing my experiences, others will be inspired to set high goals for themselves.

Q: Have you experienced any particular challenges as a female astronaut? How have you stayed motivated in the face of such challenges?

Actually, the women astronauts who came before me performed their jobs so well that it really wasn’t an issue.  There was probably more skepticism due to my research background, given that the job is an operational one, and I didn’t have much experience in that environment. The training we’re provided helped prepare me well, as did veterans astronauts who passed on helpful tips.

Q: As a pioneer of spacecraft technology and a champion of outreach, how do you think we can inspire more women to enter STEM fields?

Use every available communications avenue to let women know about the interesting and rewarding careers in the STEM fields. The website Women@NASA profiles many women around the agency, having them describe in their own words what they do and the path that led them to their careers. And since girls start making choices in middle school that can limit their options later on, there’s a section on the website aimed specifically at middle school girls called Aspire to Inspire featuring women at Johnson Space Center. NASA has also made great use of many social media platforms to spread the word on what we are doing in space exploration, both human and robotics. From the first flyby of Pluto to the completion of a one-year mission onboard the International Space Station, this has been an exciting year for NASA.

If I am in the path of totality (Hopkinsville, KY) when can I take off my glasses to view the eclipse? Can I keep them off for the entire 2 minutes and 40 seconds?

If you are viewing the partial eclipse or lead up to totality, once you no longer can see any light through your eclipse glasses, then you can take them off. As long as the moon is fully covering the Sun you are safe. I would err on the side of caution and look away from the Sun a few moments before it’s over. This is also a great time to see what is happening around you! The animals should be responding differently than normal and this would be a great time to see that. 

The trickster “Blinking Planetary”

Planetary nebula NGC 6826 is located about 4,200 light years from Earth in Cygnus. When observers look directly at it through a small telescope, they typically see only the nebula’s sparkling-white central star. However, by averting one’s gaze, glancing away from the central star, the nebula’s bulbous dust clouds come into view. This optical trickery earned this planetary nebula the name the "Blinking Planetary.” 

Over the next several thousand years, the nebula will gradually disperse into space, and then the central star will slowly cool as it radiates its energy for billions of years as a white dwarf.

See the Closest Ever Images of the Sun

Solar Orbiter just released its first scientific data — including the closest images ever taken of the Sun.

Launched on February 9, 2020, Solar Orbiter is a collaboration between the European Space Agency and NASA, designed to study the Sun up close. Solar Orbiter completed its first close pass of the Sun on June 15, flying within 48 million miles of the Sun’s surface.

This is already closer to the Sun than any other spacecraft has taken pictures (our Parker Solar Probe mission has flown closer, but it doesn’t take pictures of the Sun). And over the next seven years, Solar Orbiter will inch even closer to the Sun while tilting its orbit above the plane of the planets, to peek at the Sun’s north and south poles, which have never been imaged before.

Here’s some of what Solar Orbiter has seen so far.

The Sun up close

Solar Orbiter’s Extreme Ultraviolet Imager, or EUI, sees the Sun in wavelengths of extreme ultraviolet light that are invisible to our eyes.

EUI captured images showing “campfires” dotting the Sun. These miniature bright spots are over a million times smaller than normal solar flares. They may be the nanoflares, or tiny explosions, long thought to help heat the Sun’s outer atmosphere, or corona, to its temperature 300 times hotter than the Sun’s surface. It will take more data to know for sure, but one thing’s certain: In EUI’s images, these campfires are all over the Sun.

The Polar and Helioseismic Imager, or PHI, maps the Sun’s magnetic field in a variety of ways. These images show several of the measurements PHI makes, including the magnetic field strength and direction and the speed of flow of solar material.

PHI will have its heyday later in the mission, as Solar Orbiter gradually tilts its orbit to 24 degrees above the plane of the planets, giving it a never-before-seen view of the poles. But its first images reveal the busy magnetic field on the solar surface.

Studying space

Solar Orbiter’s instruments don’t just focus on the Sun itself — it also carries instruments that study the space around the Sun and surrounding the spacecraft.

The Solar and Heliospheric Imager, or SoloHi, looks out the side of the Solar Orbiter spacecraft to see the solar wind, dust, and cosmic rays that fill the space between the Sun and the planets. SoloHi captured the relatively faint light reflecting off interplanetary dust known as the zodiacal light, the bright blob of light in the right of the image. Compared to the Sun, the zodiacal light is extremely dim – to see it, SoloHi had to reduce incoming sunlight by a trillion times. The straight bright feature on the very edge of the image is a baffle illuminated by reflections from the spacecraft’s solar array.

This first data release highlights Solar Orbiter’s images, but its in situ instruments also revealed some of their first measurements. The Solar Wind Analyser, or SWA instrument, made the first dedicated measurements of heavy ions — carbon, oxygen, silicon, and iron — in the solar wind from the inner heliosphere.

NASA Does Hurricanes

When you think of NASA, you probably think of space. Which makes sense, because space is a huge part of what we do. That being said, here at NASA we are also involved in many other research areas, and even play a role in hurricane weather forecasting.

Our satellites, computer modeling, instruments, aircraft and field missions all contribute to a mix of information used by scientists to get a better understanding of these storms. Aspects of storms from rainfall rates to surface wind speed are all analyzed to help identify the potential for storm formation or intensification.

Currently, our satellites are passing overhead as Hurricane Joaquin (above) travels through the Atlantic Ocean. Our Global Precipitation Measurement, or GPM Core satellite captured images and rainfall rates of the storm. GPM showed a large area of very intense rain, which indicates that large amounts of heat are being released into the storm’s center. This fuels the circulation and provides the means for its intensification.

Maximum sustained winds have increased to near 80 mph and additional strengthening is expected. Joaquin could become a major hurricane during the next few days.

In 2016, we’re launching the Cyclone Global Navigation Satellite System (CYGNSS), which is a constellation of eight small satellites. With this launch, we will be able to better understand the rapid intensification of hurricanes, and improve hurricane intensity forecasts.

In addition to our satellite technology, we also conduct field missions to study hurricanes. In our most recent field mission, we investigated the process that underlie hurricane formation and intensity change in the Atlantic Ocean basin.

NASA Day of Remembrance

Every year at this time, we take a moment to reflect as the NASA Family on the very broad shoulders on which we stand: the shoulders of those women and men of NASA who gave their lives so that we could continue to reach for new heights for the benefit of all humankind.

To honor our fallen heroes and friends, NASA Administrator Charles Bolden and Deputy Administrator Dava Newman spoke at a wreath-laying ceremony at Arlington National Cemetery, at the grave sites of the fallen crew.

The crew aboard the International Space Station also payed tribute with a moment of silence. 

President Barack Obama recognized the day with the release of an official statement that honors the legacy of the heroes who lost their lives helping America touch the stars.

To view the President’s full statement, visit HERE.

Thank you for keeping our fallen colleagues in your hearts and for honoring their legacy.

NASA Spotlight: Earth Climate Scientist Dr. Yolanda Shea

Dr. Yolanda Shea is a climate scientist at NASA's Langley Research Center. She’s the project scientist for the CLARREO Pathfinder (CPF) mission, which is an instrument that will launch to the International Space Station to measure sunlight reflected from Earth. It will help us understand how much heat is being trapped by our planet’s atmosphere. Her mission is designed to help us get a clearer picture than we currently have of the Earth’s system and how it is changing

Yolanda took time from studying our home planet to answer questions about her life and career! Get to know this Earth scientist:

What inspired you to study climate science?

Starting in early middle school I became interested in the explanations behind the weather maps and satellite images shown on TV. I liked how the meteorologists talked about the temperature, moisture, and winds at different heights in the atmosphere, and then put that together to form the story of our weather forecasts. This made me want to learn more about Earth science, so I went to college to explore this interest more.

The summer after my junior year of college, I had an internship during which my first assignment was to work with a program that estimated ocean currents from satellite measurements. I was fascinated in the fact that scientists had discovered a way to map ocean currents from space!

Although I had learned about Earth remote sensing in my classes, this was my first taste of working with, and understanding the details of, how we could learn more about different aspects of the physical world from satellite measurements.

This led to my learning about other ways we can learn about Earth from space, and that includes rigorous climate monitoring, which is the area I work in now.

What does a day in your life look like?

Before I start my workday, I like to take a few minutes to eat breakfast, knit (I’m loving sock knitting right now!), and listen to a podcast or audio book. Each workday really looks different for me, but regardless, most days are a combination of quieter moments that I can use for individual work and more interactive times when I’m interfacing with colleagues and talking about project or science issues. Both types of work are fun in different ways, but I’m glad I have a mixture because all researchers need that combination of deep thinking to wrap our minds around complex problems and also time to tackle those problems with others and work on solving them together.

When do you feel most connected to Earth?

I’ve always loved sunsets. I find them peaceful and beautiful, and I love how each one is unique. They are also a beautiful reminder of the versatility of reflected light, which I study. Sitting for a moment to appreciate the beauty and calm I feel during a sunset helps me feel connected to Earth.

What will your mission – CLARREO Pathfinder – tell us about Earth?

CLARREO Pathfinder (CPF) includes an instrument that will take measurements from the International Space Station and will measure reflected sunlight from Earth. One of its goals is to demonstrate that it can take measurements with high enough accuracy so that, if we have such measurements over long periods of time, like several decades, we could detect changes in Earth’s climate system. The CPF instrument will do this with higher accuracy than previous satellite instruments we’ve designed, and these measurements can be used to improve the accuracy of other satellite instruments.

How, if at all, has your worldview changed as a result of your work in climate science?

The longer I work in climate science and learn from the data about how humans have impacted our planet, the more I appreciate the fragility of our one and only home, and the more I want to take care of it.

What advice would you give your younger self?

It’s ok to not have everything figured out at every step of your career journey. Work hard, do your best, and enjoy the journey as it unfolds. You’ll inevitably have some surprises along the way, and regardless of whether they are welcome or not, you’re guaranteed to learn something.

Do you have a favorite metaphor or analogy that you use to describe what you do, and its impact, to those outside of the scientific community?

I see jigsaw puzzles as a good illustration of how different members of a science community play a diverse set of roles to work through different problems. Each member is often working on their own image within the greater puzzle, and although it might take them years of work to see their part of the picture come together, each image in the greater puzzle is essential to completing the whole thing. During my career, I’ll work on a section of the puzzle, and I hope to connect my section to others nearby, but we may not finish the whole puzzle. That’s ok, however, because we’ll hand over the work that we’ve accomplished to the next generation of scientists, and they will keep working to bring the picture to light. This is how I try to think about my role in climate science – I hope to contribute to the field in some way; the best thing about what I have done and what I will do, is that someone else will be able to build on my work and keep helping humanity come to a better understanding of our Earth system.

What is a course that you think should be part of required school curriculum?

Time and project management skills – I think students tend to learn these skills more organically from their parents and teachers, but in my experience I stumbled along and learned these skills through trial and error. To successfully balance all the different projects that I support now, I have to be organized and disciplined, and I need to have clear plans mapped out, so I have some idea of what’s coming and where my attention needs to be focused.

Another course not specifically related to my field is personal financial management. I was interested in personal finance, and that helped me to seek out information (mainly through various blogs) about how to be responsible with my home finances. There is a lot of information out there, but making sure that students have a solid foundation and know what questions to ask early on will set them to for success (and hopefully fewer mistakes) later on.

What’s the most unexpected time or place that your expertise in climate science and/or algorithms came in handy?

I think an interesting part of being an atmospheric scientist and a known sky-watcher is that I get to notice beautiful moments in the sky. I remember being on a trip with friends and I looked up (as I usually do), and I was gifted with a gorgeous sundog and halo arc. It was such a beautiful moment, and because I noticed it, my friends got to enjoy it too.

Can you share a photo or image from a memorable NASA project you’ve worked on, and tell us a little bit about why the project stood out to you?

I absolutely loved being on the PBS Kids TV Show, SciGirls for their episode SkyGirls! This featured a NASA program called Students’ Clouds Observations On-Line (S’COOL). It was a citizen science program where students from around the globe could take observations of clouds from the ground that coincided with satellite overpasses, and the intention was to help scientists validate (or check) the accuracy of the code they use to detect clouds from satellite measurements. I grew up watching educational programming from PBS, so it was an honor to be a science mentor on a TV show that I knew would reach children across the nation who might be interested in different STEM fields. In this photo, the three young women I worked with on the show and I are talking about the different types of clouds.
