Solar System: Things To Know This Week

Solar System: 5 Things To Know This Week

This month you can catch a rare sight in the pre-dawn sky: five planets at once! If you look to the south (or to the north if you’re in the southern hemisphere) between about 5:30 and 6 a.m. local time you’ll see Mercury, Venus, Saturn, Mars and Jupiter lined up like jewels on a necklace. They’re beautiful in the sky, and even more fascinating when you look closely.

This week we’re taking a tour of the planets with recent information about each:

1. Artistic License

Craters on Mercury are named for writers and artists of all kinds. There are Tolstoy, Thoreau and Tolkien craters, for example, as well as those that bear the names of the Brontës, photographer Dorothea Lange and dancer Margot Fonteyn. See the complete roster of crater names HERE.

2. Lifting the Veil of Venus

A thick covering of clouds made Venus a mystery for most of human history. In recent decades, though, a fleet of robotic spacecraft has helped us peer past the veil and learn more about this world that is so like the Earth in some ways — and in some ways it’s near opposite.

3. Curious?

Have you ever wanted to drive the Mars Curiosity rover? You can take the controls using our Experience Curiosity simulation. Command a virtual rover as you explore the terrain in Gale Crater, all using real data and images from Mars. Try it out HERE.

4. Now That’s a Super Storm

Winter weather often makes headlines on Earth — but on Jupiter there’s a storm large enough to swallow our entire planet several times over. It’s been raging for at least three hundred years! Learn about the Great Red Spot HERE.

5. Ring Watcher

This week, the Cassini spacecraft will be making high-resolution observations of Saturn’s entrancing rings. This is a simulated look at Saturn, along with actual photos of the rings from the Cassini mission.

AI, Cancer Therapy and Chemical Gardens Headed to Space Station

A new batch of science is headed to the International Space Station aboard the SpaceX Dragon on the company’s 15th mission for commercial resupply services. The spacecraft will deliver science that studies the use of artificial intelligence, plant water use all over the planet, gut health in space, more efficient drug development and the formation of inorganic structures without the influence of Earth’s gravity. 

Take a look at five investigations headed to space on the latest SpaceX resupply:

Plants regulate their temperature by releasing water through tiny pores on their leaves. If they have sufficient water they can maintain their temperature, but if water is insufficient their temperatures rise. This temperature rise can be measured with a sensor in space.

ECOSTRESS measures the temperature of plants and uses that information to better understand how much water plants need and how they respond to stress.

Spaceflight has an on impact many bodily systems. Rodent Research-7 takes a look at how the microgravity environment of space affects the community of microoganisms in the gastrointestinal tract, or microbiota.

The study also evaluates relationships between system changes, such as sleep-wake cycle disruption, and imbalance of microbial populations, to identify contributing factors and supporting development of countermeasures to protect astronaut health during long-term missions, as well as to improve the treatment of gastrointestinal, immune, metabolic and sleep disorders on Earth.

Cardiovascular diseases and cancer are the leading causes of death in developed countries. Angiex Cancer Therapy examines whether microgravity-cultured endothelial cells represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels.

Results may create a model system for designing safer drugs, targeting the vasculature of cancer tumors and helping pharmaceutical companies design safer vascular-targeted drugs.

Chemical Gardens are structures that grow during the interaction of metal salt solutions with silicates, carbonates or other selected anions. Their growth characteristics and attractive final shapes form from a complex interplay between reaction-diffusion processes and self-organization.

On Earth, gravity-induced flow due to buoyancy differences between the reactants complicates our understanding of the physics behind these chemical gardens. Conducting this experiment in a microgravity environment ensures diffusion-controlled growth and allows researchers a better assessment of initiation and evolution of these structures.

These investigations join hundreds of others currently happening aboard the orbiting laboratory.

13 Reasons to Have an Out-of-This-World Friday (the 13th)

1. Not all of humanity is bound to the ground

Since 2000, the International Space Station has been continuously occupied by humans. There, crew members live and work while conducting important research that benefits life on Earth and will even help us eventually travel to deep space destinations, like Mars.

2. We’re working to develop quieter supersonic aircraft that would allow you to travel from New York to Los Angeles in 2 hours

We are working hard to make flight greener, safer and quieter – all while developing aircraft that travel faster, and building an aviation system that operates more efficiently. Seventy years after Chuck Yeager broke the sound barrier in the Bell X-1 aircraft, we’re continuing that supersonic X-plane legacy by working to create a quieter supersonic jet with an aim toward passenger flight.

3. The spacecraft, rockets and systems developed to send astronauts to low-Earth orbit as part of our Commercial Crew Program is also helping us get to Mars

Changes to the human body during long-duration spaceflight are significant challenges to solve ahead of a mission to Mars and back. The space station allows us to perform long duration missions without leaving Earth’s orbit.

Although they are orbiting Earth, space station astronauts spend months at a time in near-zero gravity, which allows scientists to study several physiological changes and test potential solutions. The more time they spend in space, the more helpful the station crew members can be to those on Earth assembling the plans to go to Mars.

4. We’re launching a spacecraft in 2018 that will go “touch the Sun”

In the summer of 2018, we’re launching Parker Solar Probe, a spacecraft that will get closer to the Sun than any other in human history. Parker Solar Probe will fly directly through the Sun’s atmosphere, called the corona. Getting better measurements of this region is key to understanding our Sun. 

For instance, the Sun releases a constant outflow of solar material, called the solar wind. We think the corona is where this solar wind is accelerated out into the solar system, and Parker Solar Probe’s measurements should help us pinpoint how that happens.  

5. You can digitally fly along with spacecraft…that are actually in space…in real-time!

NASA’s Eyes are immersive, 3D simulations of real events, spacecraft locations and trajectories. Through this interactive app, you can experience Earth and our solar system, the universe and the spacecraft exploring them. Want to watch as our Juno spacecraft makes its next orbit around Juno? You can! Or relive all of the Voyager mission highlights in real-time? You can do that too! Download the free app HERE to start exploring.

6. When you feel far away from home, you can think of the New Horizons spacecraft as it heads toward the Kuiper Belt, and the Voyager spacecraft are beyond the influence of our sun…billions of miles away

Our New Horizons spacecraft completed its Pluto flyby in July 2015 and has continued on its way toward the Kuiper Belt. The spacecraft continues to send back important data as it travels toward deeper space at more than 32,000 miles per hour, and is ~3.2 billion miles from Earth.

In addition to New Horizons, our twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-37-year journey since their 1977 launches, they are each much farther away from Earth and the sun than Pluto. In August 2012, Voyager 1 made the historic entry into interstellar space, the region between the stars, filled with material ejected by the death of nearby stars millions of years ago.

7. There are humans brave enough to not only travel in space, but venture outside space station to perform important repairs and updates during spacewalks

Just this month (October 2017) we’ve already had two spacewalks on the International Space Station...with another scheduled on Oct. 20. 

Spacewalks are important events where crew members repair, maintain and upgrade parts of the International Space Station. These activities can also be referred to as EVAs – Extravehicular Activities. Not only do spacewalks require an enormous amount of work to prepare for, but they are physically demanding on the astronauts. They are working in the vacuum of space in only their spacewalking suit. 

8. Smart people are up all night working in control rooms all over NASA to ensure that data keeps flowing from our satellites and spacecraft

Our satellites and spacecraft help scientists study Earth and space. Missions looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.

9. A lot of NASA-developed tech has been transferred for use to the public

Our Technology Transfer Program highlights technologies that were originally designed for our mission needs, but have since been introduced to the public market. HERE are a few spinoff technologies that you might not know about.

10. We have a spacecraft currently traveling  to an asteroid to collect a sample and bring it back to Earth

OSIRIS-REx is our first-ever mission that will travel to an asteroid and bring a sample of it back to Earth. Currently, the spacecraft is on its way to asteroid Bennu where it will survey and map the object before it “high-fives” the asteroid with its robotic arm to collect a sample, which it will send to Earth.

If everything goes according to plan, on Sept. 24, 2023, the capsule containing the asteroid sample will make a soft landing in the Utah desert.

11. There are Earth-sized planets outside our solar system that may be habitable

To date, we have confirmed 3,000+ exoplanets, which are planets outside our solar system that orbit a Sun-like star. Of these 3,000, some are in the habitable zone – where the temperature is just right for liquid water to exist on the surface.  

Recently, our Spitzer Space Telescope revealed the first known system of SEVEN Earth-size planets around a single star. Three of these plants are firmly in the habitable zone, and could have liquid water on the surface, which is key to life as we know it.

12. Earth looks like art from space

In 1960, the United States put its first Earth-observing environmental satellite into orbit around the planet. Over the decades, these satellites have provided invaluable information, and the vantage point of space has provided new perspectives on Earth.

The beauty of Earth is clear, and the artistry ranges from the surreal to the sublime.

13. We’re building a telescope that will be able to see the first stars ever formed in the universe

Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!

Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.

Happy Friday the 13th! We hope it’s out-of-this-world!

Celebrating Women’s Equality Day Across NASA

August 26 is celebrated in the United States as Women’s Equality Day. On this day in 1920, the Nineteenth Amendment was signed into law and American women were granted the constitutional right to vote. The suffragists who fought hard for a woman’s right to vote opened up doors for trailblazers who have helped shape our story of spaceflight, research and discovery. On Women’s Equality Day, we celebrate women at NASA who have broken barriers, challenged stereotypes and paved the way for future generations. This list is by no means exhaustive. 

Rocket Girls and the Advent of the Space Age

In the earliest days of space exploration, most calculations for early space missions were done by “human computers,” and most of these computers were women. These women's calculations helped the U.S. launch its first satellite, Explorer 1. This image from 1953, five years before the launch of Explorer 1, shows some of those women on the campus of the Jet Propulsion Laboratory (JPL).

These women were trailblazers at a time when most technical fields were dominated by white men. Janez Lawson (seen in this photo), was the first African American hired into a technical position at JPL. Having graduated from UCLA with a bachelor's degree in chemical engineering, she later went on to have a successful career as a chemical engineer.

Katherine Johnson: A Champion for Women’s Equality

Mathematician Katherine Johnson, whose life story was told in the book and film "Hidden Figures," is 101 years old today! Coincidentally, Johnson’s birthday falls on August 26: which is appropriate, considering all the ways that she has stood for women’s equality at NASA and the country as a whole.

Johnson began her career in 1953 at the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, one of a number of African-American women hired to work as "human computers.” Johnson became known for her training in geometry, her leadership and her inquisitive nature; she was the only woman at the time to be pulled from the computing pool to work with engineers on other programs.

Johnson was responsible for calculating the trajectory of the 1961 flight of Alan Shepard, the first American in space, as well as verifying the calculations made by electronic computers of John Glenn’s 1962 launch to orbit and the 1969 Apollo 11 trajectory to the moon. She was awarded the Presidential Medal of Freedom, the nation's highest civilian honor, by President Barack Obama on Nov. 24, 2015.

JoAnn Morgan: Rocket Fuel in Her Blood 

JoAnn Morgan was an engineer at Kennedy Space Center at a time when the launch room was crowded with men. In spite of working for all of the Mercury, Gemini and Apollo programs, and being promoted to a senior engineer, Morgan was still not permitted in the firing room at liftoff — until Apollo 11, when her supervisor advocated for her because of her superior communication skills. Because of this, Morgan was the instrumentation controller — and the only woman — in the launch room for the Apollo 11 liftoff. 

Morgan’s career at NASA spanned over 45 years, and she continued to break ceiling after ceiling for women involved with the space program. She 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.

Oceola (Ocie) Hall: An Advocate for NASA Women 

Oceola Hall worked in NASA’s Office of Diversity and Equal Opportunity for over 25 years. She was NASA’s first agency-wide Federal Women’s program manager, from 1974 – 1978. Hall advanced opportunities for NASA women in science, engineering and administrative occupations. She was instrumental in initiating education programs for women, including the Simmons College Strategic Leadership for Women Program.

Hall’s outstanding leadership abilities and vast knowledge of equal employment laws culminated in her tenure as deputy associate administrator for Equal Opportunity Programs, a position she held for five years. Hall was one among the first African-American women to be appointed to the senior executive service of NASA. This photo was taken at Marshall during a Federal Women’s Week Luncheon on November 11, 1977 where Hall served as guest speaker.

Hall was known for saying, “You have to earn your wings every day.”

Sally Ride: Setting the Stage for Women in Space

The Astronaut Class of 1978, otherwise known as the “Thirty-Five New Guys,” was NASA’s first new group of astronauts since 1969. This class was notable for many reasons, including having the first African-American and first Asian-American astronauts and the first women.

Among the first women astronauts selected was Sally Ride. On June 18, 1983, Ride became the first American woman in space, when she launched with her four crewmates aboard the Space Shuttle Challenger on mission STS-7. On that day, Ride made history and paved the way for future explorers.

When those first six women joined the astronaut corps in 1978, they made up nearly 10 percent of the active astronaut corps. In the 40 years since that selection, NASA selected its first astronaut candidate class with equal numbers of women and men, and women now comprise 34 percent of the active astronauts at NASA.

Charlie Blackwell-Thompson: First Female Launch Director 

As a part of our Artemis missions to return humans to the Moon and prepare for journeys to Mars, the Space Launch System, or SLS, rocket will carry the Orion spacecraft on an important flight test. Veteran spaceflight engineer Charlie Blackwell-Thompson will helm the launch team at Kennedy Space Center in Florida. Her selection as launch director means she will be the first woman to oversee a NASA liftoff and launch team.

"A couple of firsts here all make me smile," Blackwell-Thompson said. "First launch director for the world's most powerful rocket — that's humbling. And I am honored to be the first female launch director at Kennedy Space Center. So many amazing women that have contributed to human space flight, and they blazed the trail for all of us.”

The Future of Women at NASA

In this image, NASA astronauts Anne McClain and Christina Koch pose for a portrait inside the Kibo laboratory module on the International Space Station. Both Expedition 59 flight engineers are members of NASA's 2013 class of astronauts.   

As we move forward as a space agency, embarking on future missions to the Moon, Mars and beyond, we reflect on the women who blazed the trail and broke glass ceilings. Without their perseverance and determination, we would not be where we are today.

Who is the First Woman? Meet our new graphic novel hero!

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.

So what's up with that lunar crater?

Did Callie pass her math class?

And where did RT come from?

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.

Which Landsat Image Do You Love?

Feeling competitive? We’ve got a game for you to play in! Tournament Earth: The Landsat Games is happening right now, and as we get to the final entries, the competition is heating up.

You can help us pick the winner by voting for one of the remaining four Landsat images of our home planet! Our competition started with 32 images, divided into categories by what they show: land, water, ice & snow, and human impact.

So, what do you think? Which one of these images is going for gold?

Land

First up, we have an image of the Markha River and surrounding Central Siberian Plateau, acquired in 2020 by Landsat 8. The hypnotic undulations of striping across the landscape carried this image to victory over the rest of the Land images -- a particularly tough category, given that these images all come from Landsat.

Water

It’s not all land, though! The bright blues and greens of this false-color image of the Atchafalaya Delta in Louisiana helped carry it to victory in the Water category. The image, taken in 2020 by Landsat 8, shows a region that’s subject to erosion of land by wind and rising sea levels.

Ice & Snow

Brrr! Did it get cold in here? That’s the finalist from the Ice and Snow category, an image of sea ice around Russia’s New Siberian Islands. The image, collected by Landsat 8 in June 2016, shows sea ice during its annual seasonal breakup.

Human Impact

Humans have been shaping the planet around us for hundreds of years. Some changes, like rice fields in the Sacramento Valley, are visible from space. Landsat 8 collected this false-color image of flooded rice fields in December 2018.

So, now it’s up to you! Which image is your favorite? There can only be one winner of Tournament Earth: The Landsat Games. Get your vote in, and then get ready to watch as we launch the next Landsat satellite, Landsat 9, in September.

The Landsat mission is a partnership between us at NASA and the U.S. Geological Survey. Together, we’ve been using Landsat satellites to collect nearly 50 years of images of our home planet.

NASA’s View of COVID-19

#COVID19 led to changes in human activities around the globe. We can see some of these changes from space. Some bodies of water have run clearer, emissions of pollutants have temporarily declined, and transportation and shipment of goods have decreased.

Along with our partner agencies – ESA and JAXA – we’re making satellite data available on the COVID-19 Earth Observation Dashboard, where you can explore some of the changes we can see from space.

But it’s not just what we can see. When the pandemic began, NASA engineers sprang into action to build ventilators, oxygen hoods and more to help save lives.

How Climate Change Showed Up in 2021

2021 was tied for the sixth-hottest year since modern record keeping began. We work together with the National Oceanic and Atmospheric Administration to track temperatures around the world and study how they change from year to year.

For decades, the overall global temperature has been increasing because of human activities. The last decade has been the warmest on record. Each individual year’s average temperature, however, can be affected by things like ocean circulation, volcanic eruptions, and specific weather events.

For instance, last year we saw the beginning of La Niña – a pattern of cooler waters in the Pacific – that was responsible for slightly cooling 2021’s average temperature. Still, last year continued a long-term trend of global warming.

Globally, Earth’s temperature in 2021 was nearly 2°F warmer than the late 19th Century, for the seventh year in a row.

The Record

Studying 142 Years

Since 1880, we can put together a consistent record of temperatures around the planet and see that it was much colder in the late-19th century. Before 1880, uncertainties in tracking global temperatures are larger. Temperatures have increased even faster since the 1970s, the result of increasing greenhouse gases in the atmosphere.

Tracking Millions of Individual Observations

Our scientists use millions of individual observations of data from more than 20,000 weather stations and Antarctic research stations, together with ship- and buoy-based observations of sea surface temperatures, to track global temperatures.

Reviewing Multiple Independent Records

Our global temperature record – GISTEMP – is one of a number of independent global temperature records, all of which show the same pattern of warming.

The Consequences

Everywhere Experiences Climate Change Differently

As Earth warms, temperature changes occur unevenly around the globe. The Arctic is currently warming about four times faster than the rest of the planet – a process called Arctic amplification. Similarly, urban areas tend to warm faster than rural areas, partly because building materials like asphalt, steel and concrete retain heat.

Droughts and Floods in Warmer Weather

More than 88% of the Western US experienced drought conditions in 2021. At the same time, communities in Western Europe saw two months’ worth of rain in 24 hours, breaking records and triggering flash floods. Because a hotter climate means more water can be carried in the atmosphere, areas like the Western US suffer drought from the increased 'thirstiness' of the atmosphere, while precipitation events can become more extreme as the amount of moisture in the atmosphere rises.

Sea Levels Continue to Rise

Melting ice raises sea levels around the world, as meltwater drains into the ocean. In addition, heat causes the ocean water to expand. From 1993 to today, global mean sea level has been rising around 3.4 millimeters per year. In 2021, sea level data from the recently launched NASA/ESA Sentinel-6 Michael Freilich mission became available to the public.

There is Hope

“This is not good news, but the fact that we are able to track this in real time and understand why it’s changing, and get people to notice why it’s changing and how we can change things to change the next trajectory, that gives me hope. Because we’re not in the dark here. We’re not the dinosaurs who are unaware the comet is coming. We can see the comet coming, and we can act.” – Dr. Gavin Schmidt, director of NASA GISS, where the global temperature record is calculated
