NASA Photographers Share Their #NASAMoonSnap

We’re getting ready to launch Artemis I, the first test flight of the rocket and spacecraft that will take future astronauts to the Moon! As we prepare for the lunar voyage of the Space Launch System (SLS) rocket and Orion spacecraft launching as early as Aug. 29, 2022, we would like you to share your excitement with us. Share all types of Moon-inspired content with us with the hashtag #NASAMoonSnap, and we will choose some entries to share on our social media platforms and during the launch broadcast. Get creative! We’re looking for Moon paintings, Moon poetry, Moon pottery, Moon latte foam art — the sky is not the limit.

Since we have the full Moon coming up on Aug. 11, we wanted to share our handy dandy Moon photography guide and inspire you with some of our NASA imagery experts’ stories on capturing the Moon.

"The first rollout of the SLS rocket with the Orion spacecraft aboard was a really exciting moment to capture. I was photographing at Kennedy Space Center in an area where many of the employees that had worked on different parts of the SLS were watching. It was so great to hear some of their stories and see their pride in helping to build this amazing rocket and spacecraft. Once the mobile launcher with SLS passed the crowds to head toward the launchpad, people began to line up in their cars to leave. I decided to stick around and try to get a closer image of the Moon with SLS. It was fairly dark by the time I made this image, so there isn’t any detail in the moon, but it’s still moving to see them next to one another and know that SLS will be closer to the Moon than Earth very soon, and will one day enable humans to land on the lunar surface again!" — Aubrey Gemignani, NASA contract Photo Archivist/Photographer, NASA Headquarters

“I set up this shot when I saw the Moon was lined up perfectly with the X-1E in front of the main entrance to Armstrong Flight Research Center one morning last year. What captured my eye about this scene was that it showcased the past and the future of NASA in one image. The X-1 was a key piece of early NACA/NASA history, and it is pointing to the Moon showing us where we are going next with Artemis. I still remember walking around on my first day at NASA and seeing all the places where history was made. I was in awe as I walked these hallowed grounds. I know that there is still a great deal of history to be written here as we strive to go higher, further and faster and I’m glad that I get to be here to document it.” — Joshua Fisher, Photographer, NASA’s Armstrong Flight Research Center

“While out capturing images of the Moon, the memories of my first day as a photographer for NASA came flooding back. One of my first memories is going to the exhibits department and getting to hold an actual Moon rock sample. That day changed my perception of the Moon forever. That moment made the Moon more than just something in the sky. It became tangible and real, and my part in all of this became clear. The honor and privilege I feel everyday is overwhelming.” — Jef Janis, Still Imaging Specialist, NASA’s Glenn Research Center

“When I can, I like my Moon photos to have a sense of place. The trick is finding a shooting position and a landmark that will fit in with the Moon’s very stringent plans for rising. I went out to shoot the Sturgeon Moon, which was also a rare blue moon, last August. As I was shooting the moonrise from the riverbank in downtown New Orleans, I was lucky to have one of the city’s iconic riverboats turn a bend and head upriver to pass beneath the Moon. Happily the river was low and I was able to scramble down the high bank to reduce the vertical distance between the quickly rising moon and the slowly passing riverboat.” — Michael DeMocker, Photographer, NASA’s Michoud Assembly Facility

“I was excited to try to capture a waning crescent Moon at dawn, even though it was late February, 20 degrees Fahrenheit and 6:30 in the morning…Nonetheless, I decided to photograph on-site at Lewis Field, and ended up using my telephoto lens to really zoom in on the Moon. In a race against the sunrise and the Moon disappearing, I was able to capture a cool shot of the Moon with a couple planes making an appearance as well (The Cleveland Hopkins Airport is right next door). Although is it me, or does one of the planes look like a rocket taking off…?” — Jordan Salkin, Scientific Imaging Specialist, NASA’s Glenn Research Center

“I have worked at NASA’s Glenn Research Center since 1990 and have enjoyed every second doing what I do to support NASA’s mission. On my first day back to work onsite after 22 months of telework I saw this beautiful sunrise with the snow, the Moon, and the hangar. It felt good to be at work seeing the landscape I was so used to seeing. I had to take these pictures to share with my colleagues. ” — Jeffrey F. Abbott, Media Support Specialist, NASA’s Glenn Research Center 

“In creating this Moon image, I almost felt pressured to find the ‘perfect location.’ The more that I thought about that prospect, the more I was drawn to using only natural elements, in my own environment. I wanted to find an image in my own backyard. This image was captured just as the Sun dropped below the horizon. I had a very short window of time when these colors would be possible. Two minutes earlier or later would have produced a totally different image. The almost abstract lines of a Maple tree in the earliest stages of budding seemed to be in concert with the waxing crescent Moon, both preparing for full bloom. Nature on display in its simplicity.” — Marvin Smith, Still Imaging Specialist Lead, NASA’s Glenn Research Center

“The lighthouse in Lorain, Ohio, has been photographed by amateur and professional photographers for decades, but I have never photographed it before. When I calculated that the path of the Moon was going to go over and past the lighthouse with a reflection over the water, I decided to give it a try. I encountered four other photographers on the same pier with me that early morning. They were huddled in the middle of the pier and I was at the end. I think I got the best photo.” — Quentin Schwinn, Scientific Photographer, NASA’s Glenn Research Center

Tour the Ocean through the Art of Sound

The ocean is one of the largest ecosystems on our planet. From eye-catching waves to the darkness of the twilight zone, it’s a place filled with mystery and rapid change.

For a scientist studying ocean color at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, there was one more question–what does it sound like?

Before long, a “symphonic ocean experience” was born, combining satellite imagery, ocean color data and programming expertise. Learn more about how data gets converted to music and sound here:

This World Oceans Day, enjoy a tour of the ocean set to sound. Here we go:

SoundCloud

Sounds of the Sea

For World Oceans Month, enjoy a moment of zen with a symphonic tour of the ocean. Experience the swirls off the coast of Río de la Plata to

Bering Sea

This melody explores the phytoplankton blooms in the western Bering Sea along the coast of the Kamchatka Peninsula collected by Aqua/MODIS on May 15, 2021. The melody created for this image was aimed at capturing the movement of the eddies or the circular movements of water. Data came from the image’s red, green, and blue channels.

Rio de la Plata

This melody explores a spring bloom in the South Atlantic Ocean off the coast of Argentina, Uruguay, and Brazil, lending the water many different shades of green, blue, and brown. The Rio de la Plata estuary in the northwest corner of the above image gets most of its tan coloration from sediments suspended in the water. The melody paired with the data evokes the sediment plumes and swirls happening off the coast.

Coral Sea

Data for the sounds of the Coral Sea were collected over the course of one year from the Aqua/Modis satellite. The information was extracted from a series of 32-day rolling averages for the year 2020, displaying the movement of chlorophyll a data.

Chlorophyll a is a specific form of chlorophyll used in photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light. It is a poor absorber of green and near-green portions of the spectrum, and that’s why it appears green.

Western Australia

Off the coast of western Australia is the appearance of swirls in the ocean. To catch the movement of the Indian Ocean, data was collected from 31 days of imagery examining blue wavelengths of light. The information was gathered from the Suomi-NPP/VIIRS instrument aboard the Joint Polar Satellite System (JPSS) series of spacecraft.

The twin Voyager spacecraft, which launched in 1977, are our ambassadors to the rest of the Milky Way, destined to continue orbiting the center of our galaxy for billions of years after they stop communicating with Earth. On Aug. 25, 2012, Voyager 1 became the first human-made object to enter interstellar space, and Voyager 2 is expected to cross over in the next few years. At age 40, the Voyagers are the farthest and longest-operating spacecraft and still have plenty more to discover. This poster captures the spirit of exploration, the vastness of space and the wonder that has fueled this ambitious journey to the outer planets and beyond.

Under Pressure

Structural Tests Underway for Top of World's Most Powerful Rocket

Testing is underway at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on the agency’s new Space Launch System, the world’s most powerful rocket. SLS and NASA’s Orion spacecraft will enable deep-space missions, beginning a new era of exploration beyond Earth’s orbit.

Engineers at Marshall have stacked four qualification articles of the upper part of SLS into a 65-foot-tall test stand using more than 3,000 bolts to hold the hardware together. Tests are currently underway to ensure the rocket hardware can withstand the pressures of launch and flight. 

The integrated tests consists of:

1. Launch Vehicle Adapter

2. Frangible Joint Assembly

3. Interim Cryogenic Propulsion Stage

4. Orion Stage Adapter

Engineers are using 28 load pistons to push, pull and twist the rocket hardware, subjecting it to loads up to 40 percent greater than that expected during flight. More than 100 miles of cables are transmitting measurements across 1,900 data channels.

The Launch Vehicle Stage Adapter, LVSA, connects the SLS core stage and the Interim Cryogenic Propulsion Stage, ICPS. The LVSA test hardware is 26.5 feet tall, with a bottom diameter of 27.5 feet and a top diameter of 16.8 feet. The frangible joint, located between the LVSA and ICPS, is used to separate the two pieces of hardware during flight, allowing the ICPS to provide the thrust to send Orion onto its mission.

The ICPS is a liquid oxygen/liquid hydrogen-based system that will give Orion the big, in-space push needed to fly beyond the moon before it returns to Earth on the first flight of SLS in 2018. For this test series, the fuel tanks are filled with nonflammable liquid nitrogen and pressurized with gaseous nitrogen to simulate flight conditions. The nitrogen is chilled to the same temperature as the oxygen and hydrogen under launch conditions.

The Orion Stage Adapter connects the Orion spacecraft to the ICPS. It is 4.8 feet tall, with a 16.8-foot bottom diameter and 18-foot top diameter.

The first integrated flight for SLS and Orion will allow NASA to use the lunar vicinity as a proving ground to test systems farther from Earth, and demonstrate Orion can get to a stable orbit in the area of space near the moon in order to support sending humans to deep space, including the Journey to Mars.

Our Flying Observatory Goes to New Zealand!

Our flying observatory, called SOFIA, carries a 100-inch telescope inside a Boeing 747SP aircraft. Scientists onboard study the life cycle of stars, planets (including Pluto’s atmosphere), the area around black holes and complex molecules in space. 

Heading South

Once each year our flying observatory, SOFIA, its team and instruments travel to the Southern Hemisphere to Christchurch, New Zealand. From there the team studies stars and other objects that cannot be seen while flying in the Northern Hemisphere.

What We Study

We often study star formation in our Milky Way Galaxy. But from the Southern Hemisphere we can also study the lifecycle of stars in two other galaxies called the Magellanic Clouds. The Magallenic Clouds have different materials in them, which changes how stars form in these galaxies. Scientists are studying these differences to better understand how the first stars in our universe formed.  

Home Away from Home

The observatory and its team use the National Science Foundation’s U.S. Antarctic Program facility at Christchurch International Airport. The Antarctic program’s off-season is June and July, so it’s an ideal time for us to use these facilities.

Another Blast of Winter

The Southern Hemisphere’s seasons are opposite from our own. When we are operating from Christchurch in June and July, it’s winter. This means that the nights are very long – ideal for our nighttime observing flights, which last approximately 10 hours.

Light Show

These observations often bring us so far south that the team onboard can see the Southern Lights, also called the Aurora Australis. This is the Southern Hemisphere equivalent of the Northern Lights, or Aurora Borealis, visible near the North Pole. Auroras are caused by particles from space hitting the atmosphere near Earth’s magnetic poles. Our scientists onboard SOFIA don’t study the aurora, but they do enjoy the view.

What are Gravitational Waves?

Today, the National Science Foundation (NSF) announced the detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of ground-based observatories. But...what are gravitational waves? Let us explain:

Gravitational waves are disturbances in space-time, the very fabric of the universe, that travel at the speed of light. The waves are emitted by any mass that is changing speed or direction. The simplest example is a binary system, where a pair of stars or compact objects (like black holes) orbit their common center of mass.

We can think of gravitational effects as curvatures in space-time. Earth’s gravity is constant and produces a static curve in space-time. A gravitational wave is a curvature that moves through space-time much like a water wave moves across the surface of a lake. It is generated only when masses are speeding up, slowing down or changing direction.

Did you know Earth also gives off gravitational waves? Earth orbits the sun, which means its direction is always changing, so it does generate gravitational waves, although extremely weak and faint.

What do we learn from these waves?

Observing gravitational waves would be a huge step forward in our understanding of the evolution of the universe, and how large-scale structures, like galaxies and galaxy clusters, are formed.

Gravitational waves can travel across the universe without being impeded by intervening dust and gas. These waves could also provide information about massive objects, such as black holes, that do not themselves emit light and would be undetectable with traditional telescopes.

Just as we need both ground-based and space-based optical telescopes, we need both kinds of gravitational wave observatories to study different wavelengths. Each type complements the other.

Ground-based: For optical telescopes, Earth’s atmosphere prevents some wavelengths from reaching the ground and distorts the light that does.

Space-based: Telescopes in space have a clear, steady view. That said, telescopes on the ground can be much larger than anything ever launched into space, so they can capture more light from faint objects.

How does this relate to Einstein’s theory of relativity?

The direct detection of gravitational waves is the last major prediction of Einstein’s theory to be proven. Direct detection of these waves will allow scientists to test specific predictions of the theory under conditions that have not been observed to date, such as in very strong gravitational fields.

In everyday language, “theory” means something different than it does to scientists. For scientists, the word refers to a system of ideas that explains observations and experimental results through independent general principles. Isaac Newton's theory of gravity has limitations we can measure by, say, long-term observations of the motion of the planet Mercury. Einstein's relativity theory explains these and other measurements. We recognize that Newton's theory is incomplete when we make sufficiently sensitive measurements. This is likely also true for relativity, and gravitational waves may help us understand where it becomes incomplete.

10 Ways to Observe the Moon for International Observe the Moon Night

On Saturday, October 5, we will host the 10th annual International Observe the Moon Night. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor! This year is particularly special as we mark the 50th anniversary of the Apollo 11 Moon landing while looking forward to our Artemis program, which will send the first woman and next man to the Moon.

There are many ways to participate in International Observe the Moon Night. You can attend an event, host your own or just look up! Here are 10 of our favorite ways to observe the Moon.

1. Look up

The simplest way to observe the Moon is simply to look up. The Moon is the brightest object in our night sky, the second brightest in our daytime sky and can be seen from all around the world — from the remote and dark Atacama Desert in Chile to the brightly lit streets of Tokyo. On October 5, we have a first quarter Moon, which means that the near side of the Moon will be 50 percent illuminated. The first quarter Moon is a great phase for evening observing. Furthermore, the best lunar observing is typically along the Moon's terminator (the line between night and day) where shadows are the longest, rather than at full Moon. See the Moon phase on October 5 or any other day of the year!

2. Peer through a telescope or binoculars

Is it cloudy? Luckily, you can observe the Moon from the comfort of your own home. The Virtual Telescope Project will livestream the Moon from above the Roman skyline. Or, you can take and process your own lunar images with the MicroObservatory Robotic Telescopes. Would you prefer a movie night? There are many films that feature our nearest neighbor. Also, you can spend your evening with our lunar playlist on YouTube or this video gallery, learning about the Moon’s role in eclipses, looking at the Moon phases from the far side and seeing the latest science portrayed in super high resolution.

5. Touch the topography

Observe the Moon with your hands! If you have access to a 3D printer, you can peruse our library of 3D models and lunar landscapes. This collection of Apollo resources features 3D models of the Apollo landing sites using topographic data from LRO and the SELENE mission. The 3D printed model you see above is of the Ina D volcanic landform.

6. Make and admire Moon art

Enjoy artwork of the Moon and create your own! For messy fun, lunar crater paintings demonstrate how the lunar surface changes due to frequent meteorite impacts.

7. Listen to the Moon

Image Credit: NASA Explorers: Apollo/System Sounds

Treat your ears this International Observe the Moon Night. Our audio series, NASA Explorers: Apollo features personal stories from the Apollo era to now, including yours! You can participate by recording and sharing your own experiences of Apollo with us. Learn some lunar science with the second season of our Gravity Assist podcast with NASA Chief Scientist, Jim Green. Make a playlist of Moon-themed songs. For inspiration, check out this list of lunar tunes. We also recommend LRO’s official music video, The Moon and More, featuring Javier Colon, season 1 winner of NBC’s “The Voice.” Or you can watch this video featuring “Clair de Lune,” by French composer Claude Debussy, over and over.

8. Take a virtual field trip

Image Credit: NASA/SSERVI

Plan a lunar hike with Moon Trek. Moon Trek is an interactive Moon map made using NASA data from our lunar spacecraft. Fly anywhere you’d like on the Moon, calculate the distance or the elevation of a mountain to plan your lunar hike, or layer attributes of the lunar surface and temperature. If you have a virtual reality headset, you can experience Moon Trek in 3D.  

9. See the Moon through the eyes of a spacecraft

Image Credit: NASA/GSFC/MIT

Visible light is just one tool that we use to explore our universe. Our spacecraft contain many different types of instruments to analyze the Moon’s composition and environment. Review the Moon’s gravity field with data from the GRAIL spacecraft or decipher the maze of this slope map from the laser altimeter onboard LRO. This collection from LRO features images of the Moon’s temperature and topography. You can learn more about the different NASA missions to explore the Moon here.

10. Continue your observations throughout the year

Image Credit: NASA’s Scientific Visualization Studio/Ernie Wright

An important part of observing the Moon is to see how it changes over time. International Observe the Moon Night is the perfect time to start a Moon journal. See how the shape of the Moon changes over the course of a month, and keep track of where and what time it rises and sets. Observe the Moon all year long with these tools and techniques!

However you choose to celebrate International Observe the Moon Night, we want to hear about it! Register your participation and share your experiences on social media with #ObserveTheMoon or on our Facebook page. Happy observing!

5 Myths About Becoming a Flight Director

Have you ever wondered if you have what it takes to become a NASA Flight Director? 

They are historically well known for making difficult calls and guiding the crew through "Houston, we've had a problem" situations, but in all spaceflight operations, they are ultimately responsible for the success of the mission.

We're looking for a new class of Flight Directors to join our team, and there are a few things to know.

Here are a few myths about becoming a Flight Director:

MYTH: You have to have already been a flight controller in Mission Control at NASA to become a flight director.

FACT: Although many flight directors have previously been NASA flight controllers, that is not a prerequisite to apply. The necessary experience could come from the military, other spaceflight organizations or areas that operate in similar high-stakes conditions.

MYTH: You have to already have a special spaceship flying license to apply.

FACT: The only place to get certified is on the job at NASA. Once chosen, the new flight directors will receive training on flight control and vehicle systems, as well as operational leadership and risk management.

MYTH: All flight directors have advanced degrees like, a PhD.

FACT: While a Bachelor's degree in engineering, biological science, physical science, computer science or mathematics from an accredited university is necessary, an advanced degree is not required to become a flight director.

MYTH: Flight directors are required to have experience in the space industry.

FACT: While you need at least three years of related, progressively responsible professional experience to apply, it can come from a variety of industries as long as it represents time-critical decision-making experience in high-stress, high-risk environments.

MYTH: Only astronauts become flight directors and vice versa.

FACT: To date, only one astronaut, T.J. Creamer, has become a flight director, and no flight directors have become astronauts. However, members of the flight controller teams have become astronauts. The "capsule communicator," or CAPCOM, role in Mission Control is more often filled by astronauts because the CAPCOM is the one responsible for relaying the flight director's decisions to the astronauts in space.

Okay, but What are the requirements?

Basic Qualification Requirements

Applicants must meet the following minimum requirements before submitting an application:

Be a U.S. citizen.

Have a Bachelor's degree from an accredited institution in engineering, biological science, physical science, computer science or math.

Have at least three years of related, progressively responsible professional experience.

Applications for our next Flight Director class open on Dec. 3, 2021 and close Dec. 16, 2021! Visit: go.nasa.gov/FlightDirector
