In this undated image from the 1960s, Nancy Grace Roman sits in her office in NASA Headquarters. Roman was the first Chief of Astronomy at NASA’s Office of Space Science and the first woman to hold an executive position in the agency. In her role, she had oversight for the planning and development of programs including the Cosmic Background Explorer and the Hubble Space Telescope. Dr. Roman received her doctorate in astronomy from the University of Chicago in 1949 and joined NASA in 1959. She finished her NASA career at Goddard Space Flight Center where she served as the manager of the Astronomical Data Center. After retiring from NASA in 1979, she continued working as a contractor at Goddard. Throughout her career, Dr. Roman has…

+ NASA’s Perseverance Mars rover snapped this view of a hill in Mars’ Jezero Crater called “Santa Cruz” on April 29, 2021, the 68th Martian day, or sol, of the mission. About 20 inches (50 centimeters) across on average, the boulders in the foreground are among the type of rocks the rover team has named “Ch’al” (the Navajo term for “frog” and pronounced “chesh”). Composed of multiple images, this enhanced-color mosaic was created using the left- and right-eye views of Perseverance’s Mastcam-Z camera system, merging the scene into a single, wider view. Santa Cruz hill is a possible eroded remnant of Jezero Crater’s western delta. The hill is about 164 feet (50 meters) tall and was roughly 1.6 miles (2.5 kilometers) east of the rover…

A United Launch Alliance Atlas V 541 rocket, carrying the National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellite-T (GOES-T), soars upward after lifting off from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida on March 1, 2022. Liftoff was at 4:38 p.m. EST. GOES-T is the third satellite in the GOES-R series that will continue to help meteorologists observe and predict local weather events that affect public safety. GOES-T will be renamed GOES-18 once it reaches geostationary orbit. GOES-18 will go into operational service as GOES West to provide critical data for the U.S. West Coast, Alaska, Hawaii, Mexico, Central America, and the Pacific Ocean.

Rosemary Dobbins was an artist at the Marshall Space Flight Center. Dobbins illustrated many iconic images of the Apollo era, including this cutaway illustration of the Saturn V command module (CM) configuration. The CM included some of the most complex equipment ever sent into space at the time. The three astronaut couches were surrounded by instrument panels, navigation gear, radios, life-support systems, and small engines to keep it stable during reentry. The entire cone, 11 feet long and 13 feet in diameter, was protected by a charring heat shield. The 6.5 ton CM was all that was finally left of the 3,000-ton Saturn V vehicle that lifted off on the journey to the Moon. Women scientists, artists, and others–from Nancy Grace Roman, NASA’s first chief…

Astronaut Victor Glover was assigned to the first mission to the International Space Station onboard SpaceX’s Crew Dragon, during an event on Friday, Aug. 3, 2018, at NASA’s Johnson Space Center in Houston, Texas. Other astronauts assigned to crew the first flight tests and missions of the Boeing CST-100 Starliner and SpaceX Crew Dragon also were announced during the event. Glover piloted SpaceX’s Crew Dragon, which splashed down on May 2, 2021, that carried fellow NASA astronauts Michael Hopkins and Shannon Walker, and Japan Aerospace Exploration Agency astronaut Soichi Noguchi. The mission returned to Earth in a parachute-assisted splashdown at 2:56 a.m. EDT off the coast of Panama City, Florida. Crews aboard SpaceX recovery vessels successfully recovered the spacecraft and astronauts. In this image, Glover…

This striking image from the NASA/ESA Hubble Space Telescope showcases Arp 298, a stunning pair of interacting galaxies. Arp 298 – which comprises the two galaxies NGC 7469 and IC 5283 – lies roughly 200 million light-years from Earth in the constellation Pegasus. The larger of the two galaxies pictured here is the barred spiral galaxy NGC 7469, and IC 5283 is its diminutive companion. NGC 7469 is also host to an active, supermassive black hole and a bright ring of star clusters. The “Arp” in this galaxy pair’s name signifies that they are listed in the Atlas of Peculiar Galaxies compiled by the astronomer Halton Arp. The Atlas of Peculiar Galaxies is a gallery of weird and wonderful galaxies containing peculiar structures, featuring galaxies…

“There are few artists in the aerospace industry whose career was as varied or accomplished as Ted Brown,” so reads his artist profile on the blog numbers station by Mike Acs. Brown “began as a graphic designer with [McDonnell] Douglas in 1962, and over the next four decades carved out an enviable career: he illustrated everything from the Buck Rogers imaginings of Philip Bono, Gemini and Apollo to the Shuttle Program. His art permeates the story of space exploration. It is in industry periodicals, newspapers and books and has been since the early sixties. You know his work. He is as ubiquitous as he is anonymous and that’s something I love about him, because I imagine that is exactly how he wanted it. So, this…

This image from 2020 shows a flame that was one of many ignited as part of the Flame Design investigation inside of Combustion Integrated Rack (CIR) to investigate the amount of soot that is produced in different conditions. The yellow spots are soot clusters that glow yellow when hot. These clusters grow larger in microgravity than on Earth because the soot remains within the flame longer. The CIR was created and launched to the International Space Station in 2008. NASA continues to study the behavior of fire in space. Americans can feel safer in their homes now than decades ago thanks to studies and standards that have removed highly flammable materials in clothing, beds, and furniture. NASA relies on similar studies and standards to protect…

Melba Roy Mouton (1929-1990) was a mathematician and computer programmer in NASA’s Trajectory and Geodynamics Division, acting as the Assistant Chief of Research Programs. Mouton worked at NASA’s Goddard Space Flight Center, coding computer programs to calculate the trajectories and locations of various aircraft. She also led the group of “human computers,” who tracked the Echo satellites. Roy and her team’s computations helped produce the orbital element timetables by which millions could view the satellite from Earth as it passed overhead.

NASA’s Perseverance Mars rover landed on the Red Planet on Feb. 18, 2021, and took this selfie over a rock nicknamed “Rochette,” on Sept. 10, 2021, the 198th Martian day, or sol of the mission. Two holes can be seen where the rover used its robotic arm to drill rock core samples. See the other selfies Perseverance took on that day! Perseverance uses a camera called WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) on the end of its seven-foot-long (two-meter-long) robotic arm to take its selfies. Here’s a detailed explanation of how the rover takes selfies.
