From the Chief Historian
By Brian Odom
NASA’s is a history marked by critical decisions. From George Mueller’s 1963 decision for “all up” testing of the Saturn V rocket to Michael Griffin’s 2006 decision to launch a final servicing mission to the Hubble Space Telescope, the agency has continually met key inflection points with bold decisions. These choices, such as the decision to send a crewed Apollo 8 mission around the Moon in December 1968, stand at the center of the agency’s national legacy and promote confidence in times of crisis.

Shuttle-Centaur: Loss of Launch Vehicle Redundancy Leads to Discord
By Robert Arrighi
“Although the Shuttle/Centaur decision was very difficult to make, it is the proper thing to do, and this is the time to do it.” With those words on June 19, 1986, NASA Administrator James Fletcher canceled the intensive effort to integrate the Centaur upper stage with the Space Shuttle to launch the Galileo and Ulysses spacecraft. The decision, which was tied to increased safety measures following the loss of Challenger several months earlier, brought to the forefront the 1970s decision to launch all U.S. payloads with the Space Shuttle.

By Kate Mankowski
On January 27, 1967, Mission AS-204 (later known as Apollo 1) was conducting a simulated countdown when a fire suddenly broke out in the spacecraft, claiming the lives of astronauts Virgil I. “Gus” Grissom, Edward H. White, and Roger B. Chaffee. The disaster highlighted the risks that come with spaceflight and the work that still needed to be accomplished to meet President Kennedy’s challenge of going to the Moon before the end of the decade. With the complexity of the Apollo spacecraft, discerning the cause of the fire proved to be incredibly difficult. Continue Reading
The Fight to Fund AgRISTARS
By Brad Massey
Robert MacDonald, the manager of NASA’s Large Area Crop Inventory Experiment (LACIE), was not pleased in January 1978 after he read a draft copy of the U.S. General Accounting Office’s (GAO’s) “Crop Forecasting by Satellite: Progress and Problems” report. The draft’s authors argued that LACIE had not achieved its goals of accurately predicting harvest yields in the mid-1970s. Therefore, congressional leaders should “be aware of the disappointing performance of LACIE to date when considering the future direction of NASA’s Landsat program and the plans of the Department of Agriculture.” Continue Reading
The Hubble Space Telescope: The Right Project at the Right Time
By Jillian Rael
This year, NASA commemorates 35 years of the Hubble Space Telescope’s study of the cosmos. From observations of never-before-seen phenomena within our solar system, to the discovery of distant galaxies, the confirmation of the existence of supermassive black holes, and precision measurements of the universe’s expansion, Hubble has made incredible contributions to science, technology, and even art. Yet, for all its contemporary popularity, the Hubble program initially struggled for congressional approval and consequential funding. For its part, NASA found new ways to compromise and cut costs, while Congress evaluated national priorities and NASA’s other space exploration endeavors against the long-range value of Hubble.

Orbit Shift: How 50 Pegasi b Helped Pull NASA Toward the Stars in the 1990s
By Lois Rosson
On October 20, 1995, the New York Times reported the detection of a distant planet orbiting a Sun-like star. The star, catalogued as 51 Pegasi by John Flamsteed in the 18th century, was visible to the naked eye as part of the constellation Pegasus—and had wobbled on its axis just enough that two Swiss astronomers were able to deduce the presence of another object exerting its gravitational pull on the star’s rotation. The discovery was soon confirmed by other astronomers, and 51 Pegasi b was heralded as the first confirmed exoplanet orbiting a star similar to our own Sun. Continue Reading

By Jennifer Ross-Nazzal
In 1963, critical decisions had to be made about NASA’s upcoming Gemini missions if the nation were to achieve President John F. Kennedy’s lunar goals. Known as the bridge to Apollo, Project Gemini was critical to landing a man on the Moon by the end of the decade and returning him safely to Earth. The project would demonstrate that astronauts could rendezvous and dock their spacecraft to another space vehicle and give flight crews the opportunity to test the planned extravehicular capabilities in preparation for walking on the lunar surface on future Apollo flights. Perhaps most importantly, Gemini had to show that humans could live and work in space for long periods of time, a fiercely debated topic within and outside of the agency. Continue Reading

By Sandra Johnson
As we walked into Bob McCall’s Arizona home, it quickly became obvious that two talented and creative people lived there. Tasked with interviewing one of the first artists to be invited to join the NASA Art Program, our oral history team quickly realized the session with McCall would include a unique perspective on NASA’s history. We traveled to Arizona in the spring of 2000 to capture interviews with some of the pioneers of spaceflight and had already talked to an eclectic group of subjects in their homes, including a flight controller for both Gemini and Apollo, an astronaut who had flown on both Skylab and Space Shuttle missions, a former NASA center director, and two former Women’s Airforce Service Pilots (WASPs) who ferried airplanes during WWII. However, unlike most interviews, the setting itself provided a rare glimpse into the man and his inspiration. Continue Reading
Inside the Archives: Biomedical Branch Files

Preparations for Next Moonwalk Simulations Underway (and Underwater)
From Sunday, June 22 to Wednesday, July 2, two research aircraft will make a series of low-altitude atmospheric research flights near Philadelphia, Baltimore, and some Virginia cities, including Richmond, as well as over the Los Angeles Basin, Salton Sea, and Central Valley in California.
NASA’s P-3 Orion aircraft, based out of the agency’s Wallops Flight Facility in Virginia, along with Dynamic Aviation’s King Air B200 aircraft, will fly over parts of the East and West coasts during the agency’s Student Airborne Research Program. The science flights will be conducted between June 22 and July 2, 2025. NASA/Garon Clark Pilots will operate the aircraft at altitudes lower than typical commercial flights, executing specialized maneuvers such as vertical spirals between 1,000 and 10,000 feet, circling above power plants, landfills, and urban areas. The flights will also include occasional missed approaches at local airports and low-altitude flybys along runways to collect air samples near the surface.
The East Coast flights will be conducted between June 22 and Thursday, June 26 over Baltimore and near Philadelphia, as well as near the Virginia cities of Hampton, Hopewell, and Richmond. The California flights will occur from Sunday, June 29 to July 2.
The flights, part of NASA’s Student Airborne Research Program (SARP), will involve the agency’s Airborne Science Program’s P-3 Orion aircraft (N426NA) and a King Air B200 aircraft (N46L) owned by Dynamic Aviation and contracted by NASA. The program is an eight-week summer internship program that provides undergraduate students with hands-on experience in every aspect of a scientific campaign.
The P-3, operated out of NASA’s Wallops Flight Facility in Virginia, is a four-engine turboprop aircraft outfitted with a six-instrument science payload to support a combined 40 hours of SARP science flights on each U.S. coast. The King Air B200 will fly at the same time as the P-3 but in an independent flight profile. Students will assist in the operation of the science instruments on the aircraft to collect atmospheric data.
“The SARP flights have become mainstays of NASA’s Airborne Science Program, as they expose highly competitive STEM students to real-world data gathering within a dynamic flight environment,” said Brian Bernth, chief of flight operations at NASA Wallops.
“Despite SARP being a learning experience for both the students and mentors alike, our P-3 is being flown and performing maneuvers in some of most complex and restricted airspace in the country,” said Bernth. “Tight coordination and crew resource management is needed to ensure that these flights are executed with precision but also safely.”

4 Min Read NASA to Gather In-Flight Imagery of Commercial Test Capsule Re-Entry
During the September 2023 daytime reentry of the OSIRIS-REx sample return capsule, the SCIFLI team captured visual data similar to what they're aiming to capture during Mission Possible. Credits: NASA/SCIFLI A NASA team specializing in collecting imagery-based engineering datasets from spacecraft during launch and reentry is supporting a European aerospace company’s upcoming mission to return a subscale demonstration capsule from space.
NASA’s Scientifically Calibrated In-Flight Imagery (SCIFLI) team supports a broad range of mission needs across the agency, including Artemis, science missions like OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer), and NASA’s Commercial Crew Program. The SCIFLI team also supports other commercial space efforts, helping to develop and strengthen public-private partnerships as NASA works to advance exploration, further cooperation, and open space to more science, people, and opportunities.
Later this month, SCIFLI intends to gather data on The Exploration Company’s Mission Possible capsule as it returns to Earth following the launch on a SpaceX Falcon 9 rocket. One of the key instruments SCIFLI will employ is a spectrometer detects light radiating from the capsule’s surface, which researchers can use to determine the surface temperature of the spacecraft. Traditionally, much of this data comes from advanced Computational Fluid Dynamics modeling of what happens when objects of various sizes, shapes, and materials enter different atmospheres, such as those on Earth, Mars, or Venus.
“While very powerful, there is still some uncertainty in these Computational Fluid Dynamics models. Real-world measurements made by the SCIFLI team help NASA researchers refine their models, meaning better performance for sustained flight, higher safety margins for crew returning from the Moon or Mars, or landing more mass safely while exploring other planets,” said Carey Scott, SCIFLI capability lead at NASA’s Langley Research Center in Hampton, Virginia.

“The data will provide The Exploration Company with a little bit of redundancy and a different perspective — a decoupled data package, if you will — from their onboard sensors,” said Scott.
From the Gulfstream, SCIFLI will have the spectrometer and an ultra-high-definition telescope trained on Mission Possible. The observation may be challenging since the team will be tracking the capsule against the bright daytime sky. Researchers expect to be able to acquire the capsule shortly after entry interface, the point at roughly 200,000 feet, where the atmosphere becomes thick enough to begin interacting with a capsule, producing compressive effects such as heating, a shock layer, and the emission of photons, or light.

In addition to spectrometer data on Mission Possible’s thermal protection system, SCIFLI will capture imagery of the parachute system opening. First, a small drogue chute deploys to slow the capsule from supersonic to subsonic, followed by the deployment of a main parachute. Lastly, cloud-cover permitting, the team plans to image splashdown in the Pacific, which will help a recovery vessel reach the capsule as quickly as possible.
If flying over the ocean and capturing imagery of a small capsule as it zips through the atmosphere during the day sounds difficult, it is. But this mission, like all SCIFLI’s assignments, has been carefully modeled, choreographed, and rehearsed in the months and weeks leading up to the mission. There will even be a full-dress rehearsal in the days just before launch.
Not that there aren’t always a few anxious moments right as the entry interface is imminent and the team is looking out for its target. According to Scott, once the target is acquired, the SCIFLI team has its procedures nailed down to a — pardon the pun — science.
“We rehearse, and we rehearse, and we rehearse until it’s almost memorized,” he said.

France, enlisted NASA’s support through a reimbursable Space Act Agreement and will use SCIFLI data to advance future capsule designs.
“Working with NASA on this mission has been a real highlight for our team. It shows what’s possible when people from different parts of the world come together with a shared goal,” said Najwa Naimy, chief program officer at The Exploration Company. “What the SCIFLI team is doing to spot and track our capsule in broad daylight, over the open ocean, is incredibly impressive. We’re learning from each other, building trust, and making real progress together.”
NASA Langley is known for its expertise in engineering, characterizing, and developing spacecraft systems for entry, descent, and landing. The Gulfstream III aircraft is operated by the Flight Operations Directorate at NASA’s Armstrong Flight Research Center in Edwards, California.
