Secrets lie deep within Jupiter, shrouded in the solar system's strongest magnetic field and most lethal radiation belts. On July 4, 2016, our Juno spacecraft will plunge into uncharted territory, entering orbit around the gas giant and passing closer than any spacecraft before. Juno will see Jupiter for what it really is, but first it must pass the trial of orbit insertion. For more information: http://www.nasa.gov/juno and http://missionjuno.swri.edu.

When it comes to climate change, we play a unique role in observing and understanding changes to the planet. Thanks to NASA’s Earth observations and related research, we know our planet and its climate are changing profoundly. We also know human activities, like releasing carbon dioxide and methane into the atmosphere, are driving this change.
Not only do we make these observations, we help people and groups use this knowledge to benefit society. The work we do at NASA is critical to helping us understand the ways our planet is responding to increased temperatures.
Here are 6 ways that we are involved in climate science and informing decisions:
Just like a doctor checks your vitals when you go in for a visit, here at NASA we are constantly monitoring Earth’s vital signs - carbon dioxide levels, global temperature, Arctic sea ice minimum, the ice sheets and sea level, and more.
We use satellites in space, observations from airplanes and ships, and data collected on the ground to understand our planet and its changing climate. Scientists also use computers to model and understand what's happening now and what might happen in the future.
People who study Earth see that the planet’s climate is getting warmer. Earth's temperature has gone up more than 1 degree Celsius (~2 degrees Fahrenheit) in the last 100 years. This may not seem like much, but small changes in Earth's temperature can have big effects. The current warming trend is of particular significance, because it is predominantly the result of human activity since the mid-20th century and is proceeding at an unprecedented rate.
People drive cars. People heat and cool their houses. People cook food. All those things take energy. Human-produced greenhouse gas emissions are largely responsible for warming our planet. Burning fossil fuels -- which includes coal, oil, and natural gas -- releases greenhouse gases such as carbon dioxide into the atmosphere, where they act like an insulating blanket and trap heat near Earth’s surface.
At NASA, we use satellites and instruments on board the International Space Station to confirm measurements of atmospheric carbon levels. They’ve been increasing much faster than any other time in history.
We also monitor and track global land use. Currently, half the world's population lives in urban areas, and by 2025, the United Nations projects that number will rise to 60%.
With so many people living and moving to metropolitan areas, the scientific world recognizes the need to study and understand the impacts of urban growth both locally and globally.
The International Space Station helps with this effort to monitor Earth. Its position in low-Earth orbit provides variable views and lighting over more than 90% of the inhabited surface of Earth, a useful complement to sensor systems on satellites in higher-altitude polar orbits. This high-resolution imaging of land and sea allows tracking of urban and forest growth, monitoring of hurricanes and volcanic eruptions, documenting of melting glaciers and deforestation, understanding how agriculture may be impacted by water stress, and measuring carbon dioxide in Earth’s atmosphere.
Being able to monitor Earth’s climate from space also allows us to understand what’s driving these changes.
With the CERES instruments, which fly on multiple Earth satellites, our scientists measure the Earth’s planetary energy balance – the amount of energy Earth receives from the Sun and how much it radiates back to space. Over time, less energy being radiated back to space is evidence of an increase in Earth’s greenhouse effect. Human emissions of greenhouse gases are trapping more and more heat.
NASA scientists also use computer models to simulate changes in Earth’s climate as a result of human and natural drivers of temperature change.
These simulations show that human activities such as greenhouse gas emissions, along with natural factors, are necessary to simulate the changes in Earth’s climate that we have observed; natural forces alone can’t do so.
Global climate change has already had observable effects on the environment. Glaciers and ice sheets have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted, and trees are flowering sooner.
The effects of global climate change that scientists predicted are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
Climate modelers have predicted that, as the planet warms, Earth will experience more severe heat waves and droughts, larger and more extreme wildfires, and longer and more intense hurricane seasons on average. The events of 2020 are consistent with what models have predicted: extreme climate events are more likely because of greenhouse gas emissions.
Plants are also struggling to keep up with rising carbon dioxide levels. Plants play a key role in mitigating climate change. The more carbon dioxide they absorb during photosynthesis, the less carbon dioxide remains trapped in the atmosphere where it can cause temperatures to rise. But scientists have identified an unsettling trend – 86% of land ecosystems globally are becoming progressively less efficient at absorbing the increasing levels of carbon dioxide from the atmosphere.
Helping organizations to use all the data and knowledge NASA generates is another part of our job. We’ve helped South Dakota fight West Nile Virus, helped managers across the Western U.S. handle water, helped The Nature Conservancy protect land for shorebirds, and others. We also support developing countries as they work to address climate and other challenges through a 15-year partnership with the United States Agency for International Development.
Sustainability involves taking action now to enable a future where the environment and living conditions are protected and enhanced. We work with many government, nonprofit, and business partners to use our data and modeling to inform their decisions and actions. We are also working to advance technologies for more efficient flight, including hybrid-electric propulsion, advanced materials, artificial intelligence, and machine learning.
These advances in research and technology will not only bring about positive changes to the climate and the world in which we live, but they will also drive the economic engine of America and our partners in industry, to remain the world-wide leader in flight development.
We partner with the private sector to facilitate the transfer of our research and NASA-developed technologies. Many innovations originally developed for use in the skies above help make life more sustainable on Earth. For example:
Our Earth-observing satellites help farmers produce more with less water.
Expertise in rocket engineering led to a technique that lessens the environmental impact of burning coal.
A fuel cell that runs equipment at oil wells reduces the need to vent greenhouse gases.
Sea level rise in the two-thirds of Earth covered by water may jeopardize up to two-thirds of NASA's infrastructure built within mere feet of sea level.
Some NASA centers and facilities are located in coastal real estate because the shoreline is a safer, less inhabited surrounding for launching rockets. But now these launch pads, laboratories, airfields, and testing facilities are potentially at risk because of sea level rise. We’ve worked internally at NASA to identify climate risks and support planning at our centers.
Climate change is one of the most complex issues facing us today. It involves many dimensions – science, economics, society, politics, and moral and ethical questions – and is a global problem, felt on local scales, that will be around for decades and centuries to come. With our Eyes on the Earth and wealth of knowledge on the Earth’s climate system and its components, we are one of the world’s experts in climate science.

When we think about what makes a planet habitable, we’re often talking about water. With abundant water in liquid, gas (vapor) and solid (ice) form, Earth is a highly unusual planet. Almost 70% of our home planet’s surface is covered in water!
But about 97% of Earth’s water is salty – only a tiny amount is freshwater: the stuff humans, pets and plants need to survive.
Water on our planet is constantly moving, and not just geographically. Water shifts phases from ice to water to vapor and back, moving through the planet’s soils and skies as it goes.
That’s where our satellites come in.
Look at the Midwestern U.S. this spring, for example. Torrential rain oversaturated the soil and overflowed rivers, which caused severe flooding, seen by Landsat.
Our satellites also tracked a years-long drought in California. Between 2013 and 2014, much of the state turned brown, without visible green.
It’s not just rain. Where and when snow falls – and melts – is changing, too. The snow that falls and accumulates on the ground is called snowpack, which eventually melts and feeds rivers used for drinking water and crop irrigation. When the snow doesn’t fall, or melts too early, communities go without water and crops don’t get watered at the right time.
Even when water is available, it can become contaminated by blooms of phytoplankton, like cyanobacteria . Also known as blue-green algae, these organisms can make humans sick if they drink the water. Satellites can help track algae from space, looking for the brightly colored blooms against blue water.
Zooming even farther back, Earth’s blue water is visible from thousands of miles away. The water around us makes our planet habitable and makes our planet shine blue among the darkness of space.
Knowing where the water is, and where it’s going, helps people make better decisions about how to manage it. Earth’s climate is changing rapidly, and freshwater is moving as a result. Some places are getting drier and some are getting much, much wetter. By predicting droughts and floods and tracking blooms of algae, our view of freshwater around the globe helps people manage their water.

As the Apollo 11 mission lifted off on the Saturn V rocket, propelling humanity to the surface of the Moon for the very first time, members of the team inside Launch Control Center watched through a window.
The room was crowded with men in white shirts and dark ties, watching attentively as the rocket thrust into the sky. But among them sat one woman, seated to the left of center in the third row in the image below. In fact, this was the only woman in the launch firing room for the Apollo 11 liftoff.
This is JoAnn Morgan, the instrumentation controller for Apollo 11. Today, this is what Morgan is most known for. But her career at NASA spanned over 45 years, and she continued to break ceiling after ceiling for women involved with the space program.
“It was just meant to be for me to be in the launching business,” she says. “I’ve got rocket fuel in my blood.”
Morgan was inspired to join the human spaceflight program when Explorer 1 was launched into space in 1958, the first satellite to do so from the United States. Explorer 1 was instrumental in discovering what has become known as the Van Allen radiation belt.
“I thought to myself, this is profound knowledge that concerns everyone on our planet,” she says. “This is an important discovery, and I want to be a part of this team. I was compelled to do it because of the new knowledge, the opportunity for new knowledge.”
The opportunity came when Morgan spotted an advertisement for two open positions with the Army Ballistic Missile Agency. The ad listed two Engineer’s Aide positions available for two students over the summer.
“Thank God it said ‘students’ and not ‘boys’” says Morgan, “otherwise I wouldn’t have applied.”
After Morgan got the position, the program was quickly rolled into a brand-new space exploration agency called NASA. Dr. Kurt Debus, the first director of Kennedy Space Center (KSC), looked at Morgan’s coursework and provided Morgan with a pathway to certification. She was later certified as a Measurement and Instrumentation Engineer and a Data Systems Engineer.
There was a seemingly infinite amount of obstacles that Morgan was forced to overcome — everything from obscene phone calls at her station to needing a security guard to clear out the men’s only restroom.
“You have to realize that everywhere I went — if I went to a procedure review, if I went to a post-test critique, almost every single part of my daily work — I’d be the only woman in the room,” reflects Morgan. “I had a sense of loneliness in a way, but on the other side of that coin, I wanted to do the best job I could.”
To be the instrumentation controller in the launch room for the Apollo 11 liftoff was as huge as a deal as it sounds. For Morgan, to be present at that pivotal point in history was ground-breaking: “It was very validating. It absolutely made my career.”
Much like the Saturn V rocket, Morgan’s career took off. She was the first NASA woman to win a Sloan Fellowship, which she used to earn a Master of Science degree in management from Stanford University in California. When she returned to NASA, she became a divisions chief of the Computer Systems division.
From there, Morgan excelled in many other roles, including deputy of Expendable Launch Vehicles, director of Payload Projects Management and director of Safety and Mission Assurance. She was one of the last two people who verified the space shuttle was ready to launch and the first woman at KSC to serve in an executive position, associate director of the center.
To this day, Morgan is still one of the most decorated women at KSC. Her numerous awards and recognitions include an achievement award for her work during the activation of Apollo Launch Complex 39, four exceptional service medals and two outstanding leadership medals. In 1995, she was inducted into the Florida Women's Hall of Fame.
After serving as the director of External Relations and Business Development, she retired from NASA in August 2003.
Today, people are reflecting on the 50th anniversary of Apollo 11, looking back on photos of the only woman in the launch firing room and remembering Morgan as an emblem of inspiration for women in STEM. However, Morgan’s takeaway message is to not look at those photos in admiration, but in determination to see those photos “depart from our culture.”
“I look at that picture of the firing room where I’m the only woman. And I hope all the pictures now that show people working on the missions to the Moon and onto Mars, in rooms like Mission Control or Launch Control or wherever — that there will always be several women. I hope that photos like the ones I’m in don’t exist anymore.”

On the night of May 26, 2010, the Stratospheric Observatory for Infrared Astronomy, or SOFIA, the world’s largest flying observatory, first peered into the cosmos. Its mission: to study celestial objects and astronomical phenomena with infrared light. Many objects in space emit almost all their energy at infrared wavelengths. Often, they are invisible when observed in ordinary, visible light. Over the last decade, the aircraft’s 106-inch telescope has been used to study black holes, planets, galaxies, star-forming nebulas and more! The observations have led to major breakthroughs in astronomy, revolutionizing our understanding of the solar system and beyond. To celebrate its 10 years of exploration, here’s a look at the top 10 discoveries made by our telescope on a plane:
Scientists believe that around 100,000 years after the big bang, helium and hydrogen combined to make a molecule called helium hydride. Its recent discovery confirms a key part of our basic understanding of the early universe.
More than a pretty picture, this panorama of cosmic scale reveals details that can help explain how massive stars are born and what’s feeding our Milky Way galaxy's supermassive black hole.
A double-star system that is more than 300 light-years away likely had an extreme collision between two of its rocky planets. A similar event in our own solar system may have formed our Moon.
Fear not, the dark, my friend. And let the feast begin! Magnetic fields in the Cygnus A galaxy are trapping material where it is close enough to be devoured by a hungry black hole.
The planetary system around Epsilon Eridani, a star located about 10 light-years away, has an architecture remarkably similar to our solar system. What’s more, its central star is a younger, fainter version of our Sun.
Black holes in many galaxies are actively consuming material, but our Milky Way galaxy’s central black hole is relatively quiet. Observations show magnetic fields may be directing material around, not into, the belly of the beast.
Ever wonder how material leaves a galaxy? The wind flowing from the center of the Cigar Galaxy is so strong it's pulling a magnetic field — and the mass of 50 to 60 million Suns — with it.
What happens when a star goes boom? It turns out that supernova explosions can produce a substantial amount of material from which planets like Earth can form.
They say siblings need time and space to grow, but here’s one that really needs some room. A newborn star in the Orion Nebula is clearing a bubble of space around it, preventing any new luminous family members from forming nearby.
Radiation from stars is making organic molecules in nebula NGC 7023, also known as the Iris Nebula, larger and more complex. The growth of these molecules is one of the steps that could lead to the emergence of life under the right circumstances.
SOFIA is a modified Boeing 747SP aircraft that allows astronomers to study the solar system and beyond in ways that are not possible with ground-based telescopes. Find out more about the mission at www.nasa.gov/SOFIA.

2019 brought many memorable events on Planet Earth, and NASA satellites and astronauts captured a lot of the action! From new discoveries to tracking natural events and capturing amazing scenery, here are a few highlights from around the globe.

What is the best and worst thing about being in a zero gravity environment?
Swirling clouds, deep blue oceans and textured land- and icescapes are among the many faces of our planet revealed in NASA’s new photo-essay book: Earth. This collection of 69 images captured by satellites tells a story of a 4.5-billion-year-old planet where there is always something new to see. Earth is a beautiful, awe-inspiring place, and it is the only world most of us will ever know. It is your planet. It is NASA’s mission. The book is available now in hardcover and ebook, and online with interactive features.
Here are eight of those breathtaking images for your viewing pleasure.
These wide floodplains in Queensland, Australia are unique on the planet. Scientists think they are caused by the extreme variation in water and sediment discharges from the rivers. In many years there is no rainfall at all, and the rivers are effectively non-existent. In years of modest rainfall, the main channels will carry some water, sometimes spilling over into narrow water holes known as billabongs.
Every few decades, the floodplain carries extremely high discharges of water. For instance, tropical storms to the north can lead to great water flows that inundate the entire width of the floodplain. On such occasions, the floodplain appears as series of brown and green water surfaces with only tree tops indicating the location of the islands. Such is the case in this image taken from the International Space Station in September 2016.
A wide variety of ice forms in the Caspian Sea, which stretches from Kazakhstan to Iran. Just offshore, a well-developed expanse of consolidated ice appears bright white. Farther offshore, a gray-white field of chunky, hummocked ice has detached and is slowly drifting around a polynya, an area of open water surrounded by sea ice. That darker patch is actually growing young, thin ice and nilas, a term that designates sea ice crust up to 10 centimeters (4 inches) in thickness.
The close-up shows nilas and a white, diamond-shaped piece of ice. It might look like this chunk is on the move, cutting a path through thinner ice. But it’s more likely that the “diamond” was stuck to the sea bottom and the wind pushed ice around it.
The Tsauchab River is a famous landmark for the people of Namibia and tourists. Yet few people have ever seen the river flowing with water. In December 2009, an astronaut on the International Space Station caught this glimpse of the Tsauchab River bed jutting into the sea of red dunes. It ends in a series of light-colored, silty mud holes on the dry lake floor.
Like several other rivers around the Namib Desert, the Tsauchab brings sediment down from the hinterland toward the coastal lowland. This sediment is then blown from the river beds, and over tens of millions of years it has accumulated as the red dunes of the Namib Sand Sea.
The circular pattern of New Zealand’s Egmont National Park stands out from space as a human fingerprint on the landscape. The park protects the forested and snow-capped slopes around Mount Taranaki (Mount Egmont to British settlers). It was established in 1900, when officials drew a radius of 10 kilometers around the volcanic peak. The colors differentiate the protected forest (dark green) from once-forested pasturelands (light- and brown-green).
Named by the native Maori people, Taranaki stands 2,518 meters (8,260 feet) tall, and it is one of the world’s most symmetric volcanoes. It first became active about 135,000 years ago. By dating lava flows, geologists have figured out that small eruptions occur roughly every 90 years and major eruptions every 500 years. Landsat 8 acquired this image of Taranaki and the park in July 2014.
In October 2014, the eye of Hurricane Gonzalo passed right over Bermuda. In the process, the potent storm stirred up the sediments in the shallow bays and lagoons around the island, spreading a huge mass of sediment across the North Atlantic Ocean. This Landsat 8 image shows the area after Gonzalo passed through.
The suspended sediments were likely a combination of beach sand and carbonate sediments from around the shallows and reefs. Coral reefs can produce large amounts of calcium carbonate, which stays on the reef flats (where there are coralline algae that also produce carbonate) and builds up over time to form islands.
In June 2016, the Suomi NPP satellite captured this image of various cloud formations in the South Atlantic Ocean. Note how low stratus clouds framed a hole over iceberg A-56 as it drifted across the sea.
The exact reason for the hole in the clouds is somewhat of a mystery. It could have formed by chance, although imagery from the days before and after this date suggest something else was at work. It could be that the relatively unobstructed path of the clouds over the ocean surface was interrupted by thermal instability created by the iceberg. In other words, if an obstacle is big enough, it can divert the low-level atmospheric flow of air around it, a phenomenon often caused by islands.
Along the muddy Mania River, midday clouds form over the forested land but not the water. In the tropical rainforests of Madagascar, there is ample moisture for cloud formation. Sunlight heats the land all day, warming that moist air and causing it to rise high into the atmosphere until it cools and condenses into water droplets. Clouds generally form where air is ascending (over land in this case), but not where it is descending (over the river). Landsat 8 acquired this image in January 2015.
Stretching from tropical Florida to the doorstep of Europe, the Gulf Stream carries a lot of heat, salt, and history. This river of water is an important part of the global ocean conveyor belt, moving water and heat from the Equator toward the far North Atlantic. It is one of the strongest currents on Earth and one of the most studied. Its discovery is often attributed to Benjamin Franklin, though sailors likely knew about the current long before they had a name for it.
This image shows a small portion of the Gulf Stream off of South Carolina as it appeared in infrared data collected by the Landsat 8 satellite in April 2013. Colors represent the energy—heat—being emitted by the water, with cooler temperatures in purple and the warmest water being nearly white. Note how the Gulf Stream is not a uniform band but instead has finer streams and pockets of warmer and colder water.
These images are just a few from our new book called Earth. Explore the other 61 images here.

Do you listen to music in space? If so, what are you jamming to?
Artemis is the first step in the next era of human exploration. This time when we go to the Moon, we're staying, to study and learn more than ever before. We’ll test new technologies and prepare for our next giant leap – sending astronauts to Mars.
Artemis missions will achieve many historic feats, like landing the first woman and first person of color on the Moon.
With today’s release of our graphic novel First Woman: NASA’s Promise for Humanity you don’t have to wait to join us on an inspiring adventure in space.
Meet Commander Callie Rodriguez, the first woman to explore the Moon – at least in the comic book universe.
In Issue No. 1: Dream to Reality, Callie, her robot sidekick RT, and a team of other astronauts are living and working on the Moon in the not-too-distant future. Like any good, inquisitive robot, RT asks Callie how he came to be – not just on the Moon after a harrowing experience stowed in the Orion capsule – but about their origin story, if you will.
From her childhood aspirations of space travel to being selected as an astronaut candidate, Callie takes us on her trailblazing journey to the Moon.
As they venture out to check on a problem at a lunar crater, Callie shares with RT and the crew that she was captivated by space as a kid, and how time in her father’s autobody shop piqued her interest in building things and going places.
Callie learned at a young age that knowledge is gained through both success and failure in the classroom and on the field.
Through disappointment, setbacks, and personal tragedy, Callie pursues her passions and eventually achieves her lifelong dream of becoming an astronaut – a road inspired by the real lives of many NASA astronauts living and working in space today.
Be a part of the adventure: read (or listen to) the full First Woman story and immerse yourself in a digital experience through our first-ever extended reality-enabled graphic novel.
