Celebrating Women’s Equality Day Across NASA
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.

Making the Skies Safe for Unmanned Aircraft
Unmanned Aircraft Systems (commonly known as UAS or drones) are typically a smaller aircraft that fly without an onboard pilot. Currently used for research, testing, and aerial-visual purposes, these vehicles could one day carry cargo, or even passengers, through countryside and city landscapes.
UAS are a key component of our Unmanned Aircraft Systems Integration in the National Aairspace Ssystem (UAS in the NAS) project. Our research will help develop the rules so that unmanned aircraft can safely coexist with manned aircraft in the national airspace.
We collaborate with private companies, like Navmar Applied Science Corporation (NASC), to research and test aerodynamically efficient UAS. We also work with government agencies like the Federal Aviation Administration (FAA) to conduct research that will contribute to setting standards and certifications.
We are leading the nation to open a new era in air transportation called Advanced Air Mobility (AAM). AAM will enable safe, sustainable, affordable, and accessible aviation that moves people and cargo between places using a transformed air transportation system and revolutionary new aircraft.
With new cost-and-fuel efficient aircraft and technologies becoming available, UAS will provide substantial benefit to U.S. industry and the public. Such benefits include air-lifted organ transplant deliveries that arrive more quickly and safely than ever before; and search and rescue missions performed with increased speed and accuracy.
There are other benefits too, like pizza being air- dropped to your front door, and less package delivery trucks on the road. The burgeoning landscape of AAM holds many potentials – and it’s our job to help safely and sustainably map out and navigate what that future landscape looks like.

Blowing Bubbles in the Gamma-ray Sky
Did you know our Milky Way galaxy is blowing bubbles? Two of them, each 25,000 light-years tall! They extend above and below the disk of the galaxy, like the two halves of an hourglass. We can’t see them with our own eyes because they’re only apparent in gamma-ray light, the highest-energy light in the universe.
We didn’t even know these humongous structures were smack in the middle of our galaxy until 2010. Scientists found them when they analyzed the first two years of data from NASA’s Fermi Gamma-ray Space Telescope. They dubbed them the “Fermi bubbles” and found that in addition to being really big and spread out, they seem to have well-defined edges. The bubbles’ shape and the light they give off led scientists to think they were created by a rapid release of energy. But by what? And when?
One possible explanation is that they could be leftovers from the last big meal eaten by the supermassive black hole at the center of our galaxy. This monster is more than 4 million times the mass of our own Sun. Scientists think it may have slurped up a big cloud of hydrogen between 6 and 9 million years ago and then burped jets of hot gas that we see in gamma rays and X-rays.
Another possible explanation is that the bubbles could be the remains of star formation. There are massive clusters of stars at very the center of the Milky Way — sometimes the stars are so closely packed they’re a million times more dense than in the outer suburb of the galaxy where we live. If there was a burst of star formation in this area a few million years ago, it could have created the surge of gas needed to in turn create the Fermi bubbles.
It took us until 2010 to see these Fermi bubbles because the sky is filled with a fog of other gamma rays that can obscure our view. This fog is created when particles moving near light speed bump into gas, dust, and light in the Milky Way. These collisions produce gamma rays, and scientists had to factor out the fog to unveil the bubbles.
Scientists continue to study the possible causes of these massive bubbles using the 10 years of data Fermi has collected so far. Fermi has also made many other exciting discoveries — like the the collision of superdense neutron stars and the nature of space-time. Learn more about Fermi and how we’ve been celebrating its first decade in space.

In Conversation with the Sun: Parker Solar Probe Communications
Our Sun powers life on Earth. It defines our days, nourishes our crops and even fuels our electrical grids. In our pursuit of knowledge about the universe, we’ve learned so much about the Sun, but in many ways we’re still in conversation with it, curious about its mysteries.
Parker Solar Probe will advance this conversation, flying through the Sun’s atmosphere as close as 3.8 million miles from our star’s surface, more than seven times closer to it than any previous spacecraft. If space were a football field, with Earth at one end and the Sun at the other, Parker would be at the four-yard line, just steps away from the Sun! This journey will revolutionize our understanding of the Sun, its surface and solar winds.
Supporting Parker on its journey to the Sun are our communications networks. Three networks, the Near Earth Network, the Space Network and the Deep Space Network, provide our spacecraft with their communications, delivering their data to mission operations centers. Their services ensure that missions like Parker have communications support from launch through the mission.
For Parker’s launch on Aug. 12, the Delta IV Heavy rocket that sent Parker skyward relied on the Space Network. A team at Goddard Space Flight Center’s Networks Integration Center monitored the launch, ensuring that we maintained tracking and communications data between the rocket and the ground. This data is vital, allowing engineers to make certain that Parker stays on the right path towards its orbit around the Sun.
The Space Network’s constellation of Tracking and Data Relay Satellites (TDRS) enabled constant communications coverage for the rocket as Parker made its way out of Earth’s atmosphere. These satellites fly in geosynchronous orbit, circling Earth in step with its rotation, relaying data from spacecraft at lower altitudes to the ground. The network’s three collections of TDRS over the Atlantic, Pacific and Indian oceans provide enough coverage for continuous communications for satellites in low-Earth orbit.
The Near Earth Network’s Launch Communications Segment tracked early stages of Parker's launch, testing our brand new ground stations’ ability to provide crucial information about the rocket’s initial velocity (speed) and trajectory (path). When fully operational, it will support launches from the Kennedy spaceport, including upcoming Orion missions. The Launch Communications Segment’s three ground stations are located at Kennedy Space Center; Ponce De Leon, Florida; and Bermuda.
When Parker separated from the Delta IV Heavy, the Deep Space Network took over. Antennas up to 230 feet in diameter at ground stations in California, Australia and Spain are supporting Parker for its 24 orbits around the Sun and the seven Venus flybys that gradually shrink its orbit, bringing it closer and closer to the Sun. The Deep Space Network is delivering data to mission operations centers and will continue to do so as long as Parker is operational.
Near the Sun, radio interference and the heat load on the spacecraft’s antenna makes communicating with Parker a challenge that we must plan for. Parker has three distinct communications phases, each corresponding to a different part of its orbit.
When Parker comes closest to the Sun, the spacecraft will emit a beacon tone that tells engineers on the ground about its health and status, but there will be very little opportunity to command the spacecraft and downlink data. High data rate transmission will only occur during a portion of Parker’s orbit, far from the Sun. The rest of the time, Parker will be in cruise mode, taking measurements and being commanded through a low data rate connection with Earth.
Communications infrastructure is vital to any mission. As Parker journeys ever closer to the center of our solar system, each byte of downlinked data will provide new insight into our Sun. It’s a mission that continues a conversation between us and our star that has lasted many millions of years and will continue for many millions more.

Sharpening Our View of Climate Change with the Plankton, Aerosol, Cloud, ocean Ecosystem Satellite
As our planet warms, Earth’s ocean and atmosphere are changing.
Climate change has a lot of impact on the ocean, from sea level rise to marine heat waves to a loss of biodiversity. Meanwhile, greenhouse gases like carbon dioxide continue to warm our atmosphere.
NASA’s upcoming satellite, PACE, is soon to be on the case!
Set to launch on Feb. 6, 2024, the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission will help us better understand the complex systems driving the global changes that come with a warming climate.
Earth’s ocean is becoming greener due to climate change. PACE will see the ocean in more hues than ever before.
While a single phytoplankton typically can’t be seen with the naked eye, communities of trillions of phytoplankton, called blooms, can be seen from space. Blooms often take on a greenish tinge due to the pigments that phytoplankton (similar to plants on land) use to make energy through photosynthesis.
In a 2023 study, scientists found that portions of the ocean had turned greener because there were more chlorophyll-carrying phytoplankton. PACE has a hyperspectral sensor, the Ocean Color Instrument (OCI), that will be able to discern subtle shifts in hue. This will allow scientists to monitor changes in phytoplankton communities and ocean health overall due to climate change.
Phytoplankton play a key role in helping the ocean absorb carbon from the atmosphere. PACE will identify different phytoplankton species from space.
With PACE, scientists will be able to tell what phytoplankton communities are present – from space! Before, this could only be done by analyzing a sample of seawater.
Telling “who’s who” in a phytoplankton bloom is key because different phytoplankton play vastly different roles in aquatic ecosystems. They can fuel the food chain and draw down carbon dioxide from the atmosphere to photosynthesize. Some phytoplankton populations capture carbon as they die and sink to the deep ocean; others release the gas back into the atmosphere as they decay near the surface.
Studying these teeny tiny critters from space will help scientists learn how and where phytoplankton are affected by climate change, and how changes in these communities may affect other creatures and ocean ecosystems.
Climate models are one of our most powerful tools to understand how Earth is changing. PACE data will improve the data these models rely on.
The PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light.
With two instruments called polarimeters, SPEXone and HARP2, PACE will allow scientists to measure the size, composition, and abundance of these microscopic particles in our atmosphere. This information is crucial to figuring out how climate and air quality are changing.
PACE data will help scientists answer key climate questions, like how aerosols affect cloud formation or how ice clouds and liquid clouds differ.
It will also enable scientists to examine one of the trickiest components of climate change to model: how clouds and aerosols interact. Once PACE is operational, scientists can replace the estimates currently used to fill data gaps in climate models with measurements from the new satellite.
With a view of the whole planet every two days, PACE will track both microscopic organisms in the ocean and microscopic particles in the atmosphere. PACE’s unique view will help us learn more about the ways climate change is impacting our planet’s ocean and atmosphere.

Guy Bluford Changed the Course of Space History
On Aug. 30, 1983, Guion Bluford, better known as Guy, became the first African American to fly to space. An accomplished jet pilot and aerospace engineer, Bluford became part of NASA’s 1978 astronaut class that included the first African American, the first Asian American, and the first women astronauts.
He and the other crew members of mission STS-8 were aboard the orbiter Challenger as it lifted off from Kennedy Space Center in Florida; it was the first nighttime launch and landing of the Space Shuttle program. While aboard, he and the other crew members deployed the Indian National Satellite (INSAT-1B), operated a Canadian-built robot arm, conducted experiments with live cell samples, and participated in studies measuring the effects of spaceflight on humans.
Guy Bluford chased his childhood dream of becoming an aerospace engineer, and in doing so, changed history and encouraged other Black astronauts to follow in his footsteps.
