Women in Exploration: From Human Computers to All-Woman Spacewalks

Since the 19th century, women have been making strides in areas like coding, computing, programming and space travel, despite the challenges they have faced. Sally Ride joined NASA in 1983 and five years later she became the first female American astronaut. Ride's accomplishments paved the way for the dozens of other women who became astronauts, and the hundreds of thousands more who pursued careers in science and technology. Just last week, we celebrated our very first #AllWomanSpacewalk with astronauts Christina Koch and Jessica Meir.

Here are just a couple of examples of pioneers who brought us to where we are today:

The Conquest of the Sound Barrier

Pearl Young was hired in 1922 by the National Advisory Committee for Aeronautics (NACA), NASA’s predecessor organization, to work at its Langley site in support in instrumentation, as one of the first women hired by the new agency. Women were also involved with the NACA at the Muroc site in California (now Armstrong Flight Research Center) to support flight research on advanced, high-speed aircraft. These women worked on the X-1 project, which became the first airplane to fly faster than the speed of sound. 

Young was the first woman hired as a technical employee and the second female physicist working for the federal government.

The Human Computers of Langley

The NACA hired five women in 1935 to form its first “computer pool”, because they were hardworking, “meticulous” and inexpensive. After the United States entered World War II, the NACA began actively recruiting similar types to meet the workload. These women did all the mathematical calculations – by hand – that desktop and mainframe computers do today.

Computers played a role in major projects ranging from World War II aircraft testing to transonic and supersonic flight research and the early space program. Women working as computers at Langley found that the job offered both challenges and opportunities. With limited options for promotion, computers had to prove that women could successfully do the work and then seek out their own opportunities for advancement.

Revolutionizing X-ray Astronomy

Marjorie Townsend was blazing trails from a very young age. She started college at age 15 and became the first woman to earn an engineering degree from the George Washington University when she graduated in 1951. At NASA, she became the first female spacecraft project manager, overseeing the development and 1970 launch of the UHURU satellite. The first satellite dedicated to x-ray astronomy, UHURU detected, surveyed and mapped celestial X-ray sources and gamma-ray emissions.

Women of Apollo

NASA’s mission to land a human on the Moon for the very first time took hundreds of thousands workers. These are some of the stories of the women who made our recent #Apollo50th anniversary possible:

• Margaret Hamilton led a NASA team of software engineers at the Massachusetts Institute of Technology and helped develop the flight software for NASA’s Apollo missions. She also coined the term “software engineering.” Her team’s groundbreaking work was perfect; there were no software glitches or bugs during the crewed Apollo missions. 

• JoAnn Morgan was the only woman working in Mission Control when the Apollo 11 mission launched. She later accomplished many NASA “firsts” for women:  NASA winner of a Sloan Fellowship, division chief, senior executive at the Kennedy Space Center and director of Safety and Mission Assurance at the agency.

• Judy Sullivan, was the first female engineer in the agency’s Spacecraft Operations organization, was the lead engineer for health and safety for Apollo 11, and the only woman helping Neil Armstrong suit up for flight.

Hidden Figures

Author Margot Lee Shetterly’s book – and subsequent movie – Hidden Figures, highlighted African-American women who provided instrumental support to the Apollo program, all behind the scenes.

• An alumna of the Langley computing pool, Mary Jackson was hired as the agency’s first African-American female engineer in 1958. She specialized in boundary layer effects on aerospace vehicles at supersonic speeds. 

• An extraordinarily gifted student, Katherine Johnson skipped several grades and attended high school at age 13 on the campus of a historically black college. Johnson calculated trajectories, launch windows and emergency backup return paths for many flights, including Apollo 11.

• Christine Darden served as a “computress” for eight years until she approached her supervisor to ask why men, with the same educational background as her (a master of science in applied mathematics), were being hired as engineers. Impressed by her skills, her supervisor transferred her to the engineering section, where she was one of few female aerospace engineers at NASA Langley during that time.

Lovelace’s Woman in Space Program

Geraldyn “Jerrie” Cobb was the among dozens of women recruited in 1960 by Dr. William Randolph "Randy" Lovelace II to undergo the same physical testing regimen used to help select NASA’s first astronauts as part of his privately funded Woman in Space Program.

Ultimately, thirteen women passed the same physical examinations that the Lovelace Foundation had developed for NASA’s astronaut selection process. They were: Jerrie Cobb, Myrtle "K" Cagle, Jan Dietrich, Marion Dietrich, Wally Funk, Jean Hixson, Irene Leverton, Sarah Gorelick, Jane B. Hart, Rhea Hurrle, Jerri Sloan, Gene Nora Stumbough, and Bernice Trimble Steadman. Though they were never officially affiliated with NASA, the media gave these women the unofficial nicknames “Fellow Lady Astronaut Trainees” and the “Mercury Thirteen.”

The First Woman on the Moon

The early space program inspired a generation of scientists and engineers. Now, as we embark on our Artemis program to return humanity to the lunar surface by 2024, we have the opportunity to inspire a whole new generation. The prospect of sending the first woman to the Moon is an opportunity to influence the next age of women explorers and achievers.

Somebody is very pleased with her Samantha Cristoforetti doll. Now she just needs an @astro_nicole doll. Let’s see if Mattel can make that happen. #stem #womeninspace #iss #internationalspacestation #nasa #spacescience #barbie #barbiedoll #mattel https://www.instagram.com/p/CU3b4dIMZ0z/?utm_medium=tumblr

Astronaut Davis At Work

The Shocking Behavior of a Speedy Star

Roguish runaway stars can have a big impact on their surroundings as they plunge through the Milky Way galaxy. Their high-speed encounters shock the galaxy, creating arcs, as seen in this newly released image from NASA’s Spitzer Space Telescope.

In this case, the speedster star is known as Kappa Cassiopeiae, or HD 2905 to astronomers. It is a massive, hot supergiant. But what really makes the star stand out in this image is the surrounding, streaky red glow of material in its path. Such structures are called bow shocks, and they can often be seen in front of the fastest, most massive stars in the galaxy.

Bow shocks form where the magnetic fields and wind of particles flowing off a star collide with the diffuse, and usually invisible, gas and dust that fill the space between stars. How these shocks light up tells astronomers about the conditions around the star and in space. Slow-moving stars like our sun have bow shocks that are nearly invisible at all wavelengths of light, but fast stars like Kappa Cassiopeiae create shocks that can be seen by Spitzer’s infrared detectors.

Incredibly, this shock is created about 4 light-years ahead of Kappa Cassiopeiae, showing what a sizable impact this star has on its surroundings. (This is about the same distance that we are from Proxima Centauri, the nearest star beyond the sun.)

The Kappa Cassiopeiae bow shock shows up as a vividly red color. The faint green features in this image result from carbon molecules, called polycyclic aromatic hydrocarbons, in dust clouds along the line of sight that are illuminated by starlight.

Delicate red filaments run through this infrared nebula, crossing the bow shock. Some astronomers have suggested these filaments may be tracing out features of the magnetic field that runs throughout our galaxy. Since magnetic fields are completely invisible themselves, we rely on chance encounters like this to reveal a little of their structure as they interact with the surrounding dust and gas.

Kappa Cassiopeiae is visible to the naked eye in the Cassiopeia constellation (but its bow shock only shows up in infrared light.)

For this Spitzer image, infrared light at wavelengths of 3.6 and 4.5 microns is rendered in blue, 8.0 microns in green, and 24 microns in red.

Materials Science Experiments Conducted at MSFC

In another first for NASA, an all-female crew of scientific experimenters began a five-day exercise on December 16, 1974, to test the feasibility of experiments that were later tested on the Space Shuttle/Spacelab missions. The experimenters, Dr. Mary H. Johnston (seated, left), Ann F. Whitaker and Carolyn S. Griner (standing, left to right), and the crew chief, Doris Chandler, spent spend eight hours each day of the mission in the Marshall Space Flight Centers General Purpose Laboratory (GPL). They conducted 11 selected experiments in materials science to determine their practical application for Spacelab missions and to identify integration and operational problems that might occur on actual missions.

N81 in the Small Magellanic Cloud

A NASA Hubble Space Telescope "family portrait" of young, ultra-bright stars nested in their embryonic cloud of glowing gases. The celestial maternity ward, called N81, is located 200,000 light-years away in the Small Magellanic Cloud (SMC), a small irregular satellite galaxy of our Milky Way. Hubble's exquisite resolution allows astronomers to pinpoint 50 separate stars tightly packed in the nebula's core within a 10 light- year diameter - slightly more than twice the distance between earth and the nearest star to our sun. The closest pair of stars is only 1/3 of a light-year apart (0.3 arcseconds in the sky). This furious rate of mass loss from these super-hot stars is evident in the Hubble picture that reveals dramatic shapes sculpted in the nebula's wall of glowing gases by violent stellar winds and shock waves. A pair of bright stars in the center of the nebula is pouring out most of the ultraviolet radiation to make the nebula glow. Just above them, a small dark knot is all that is left of the cold cloud of molecular hydrogen and dust the stars were born from. Dark absorption lanes of residual dust trisect the nebula. The nebula offers a unique opportunity for a close-up glimpse at the firestorm' accompanying the birth of extremely massive stars, each blazing with the brilliance of 300,000 of our suns. Such galactic fireworks were much more common billions of years ago in the early universe, when most star formation took place. The "natural- color" view was assembled from separate images taken with the Wide Field and Planetary Camera 2, in ultraviolet light and two narrow emission lines of ionized Hydrogen (H-alpha, H-beta).
