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.

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
By Alejandra Lopez
The Biomedical Branch Files (1966–2008) in the Johnson Space Center archives showcase the inner workings of a NASA office established to perform testing to provide a better understanding of the impacts of spaceflight on the human body. Ranging from memos and notes to documents and reports, this collection is an invaluable resource on the biomedical research done with NASA’s Apollo, Skylab, Space Shuttle, and Space Station projects. Files in the collection cover work done by groups within the branch such as the Toxicology, Microbiology, Clinical, and Biochemistry Laboratories. It also reveals the branch’s evolution and changes in its decision-making process over the years. Continue Reading

Some time ago, while visiting the Grand Canyon in Arizona, a photographer captured several short video clips of the landscape. In one of those clips, an unusual anomaly was discovered.
The original footage is only 1.9 seconds long, but within that moment, something remarkable was caught on camera. An unidentified aerial phenomenon (UAP) flashed across the frame, visible for less than a second, only noticeable when the video was paused and analyzed frame by frame.
The object was moving at an astonishing speed, covering an estimated two to three miles in under a second, far beyond the capabilities of any conventional aircraft, drone, or helicopter.
This isn’t the first time such anomalous flying objects have been observed. Their characteristics defy comparison with known aerial technology.
Some skeptics have proposed that the object might have been a rock thrown into the canyon from behind the camera. However, that explanation seems unlikely. Most people can only throw objects at speeds of 10 to 20 meters per second (approximately 22 to 45 mph). The velocity of this object far exceeded that range, and its near-invisibility in the unedited video suggests it was moving much faster.

In 2014, a massive underwater anomaly was discovered off the coast of Malibu, California, near Point Dume. The discovery was brought to public attention by researchers Maxwell, Dale Romero, and radio host Jimmy Church of Fade to Black on the Dark Matter Radio Network.
The formation appeared highly unnatural, a plateau-like structure measuring approximately 1.35 miles by 2.45 miles, located 6.66 miles from shore. Most striking was a large, arch-like entrance framed by what looked like massive support pillars, measuring roughly 2,745 feet wide and 630 feet tall. The roof of the structure appeared to be an incredibly thick slab, about 500 feet, prompting speculation that it might be resistant to even nuclear-level impacts.
At the time, widespread speculation emerged over the true nature of the formation. Many questioned whether this was a secret underwater base, possibly used by the military or even extraterrestrials.
Despite mainstream media claims that it was simply a natural geological formation, skeptics pointed to its geometric features and scale as evidence of intelligent design. Eyewitness accounts of unidentified craft entering and exiting the ocean in the same region only added fuel to the mystery.
Revisiting the coordinates of this underwater anomaly on Google Earth reveals something even more curious, the structure appears to be gone. Instead, the area is now obscured by a blurred overlay, suggesting that the imagery has been deliberately censored.
Although the angle of approach to the structure differs between the 2014 and 2023 images on Google Earth, it's clearly evident that they depict the same location and if the formation was merely a natural feature, why hide it?
Here are the coordinates: 34°1'23.31"N 118°59'45.64"W

The planet is in a polar orbit (red), perpendicular to the mutual orbit of the two brown dwarfs (blue). ESO/L. Calçada The Discovery
A newly discovered planetary system, informally known as 2M1510, is among the strangest ever found. An apparent planet traces out an orbit that carries it far over the poles of two brown dwarfs. This pair of mysterious objects – too massive to be planets, not massive enough to be stars – also orbit each other. Yet a third brown dwarf orbits the other two at an extreme distance.
Key Facts
In a typical arrangement, as in our solar system, families of planets orbit their parent stars in more-or-less a flat plane – the orbital plane – that matches the star’s equator. The rotation of the star, too, aligns with this plane. Everyone is “coplanar:” flat, placid, stately.
Not so for possible planet 2M1510 b (considered a “candidate planet” pending further measurements). If confirmed, the planet would be in a “polar orbit” around the two central brown dwarfs – in other words, its orbital plane would be perpendicular to the plane in which the two brown dwarfs orbit each other. Take two flat disks, merge them together at an angle in the shape of an X, and you have the essence of this orbital configuration.
“Circumbinary” planets, those orbiting two stars at once, are rare enough. A circumbinary orbiting at a 90-degree tilt was, until now, unheard of. But new measurements of this system, using the ESO (European Southern Observatory) Very Large Telescope in Chile, appear to reveal what scientists previously only imagined.
Details
The method by which the study’s science team teased out the planet’s vertiginous existence is itself a bit of a wild ride. The candidate planet cannot be detected the way most exoplanets – planets around other stars – are found today: the “transit” method, a kind of mini-eclipse, a tiny dip in starlight when the planet crosses the face of its star.
Instead they used the next most prolific method, “radial velocity” measurements. Orbiting planets cause their stars to rock back and forth ever so slightly, as the planets’ gravity pulls the stars one way and another; that pull causes subtle, but measurable, shifts in the star’s light spectrum. Add one more twist to the detection in this case: the push-me-pull-you effect of the planet on the two brown dwarfs’ orbit around each other. The path of the brown dwarf pair’s 21-day mutual orbit is being subtly altered in a way that can only be explained, the study’s authors conclude, by a polar-orbiting planet.
Fun Facts
Only 16 circumbinary planets – out of more than 5,800 confirmed exoplanets – have been found by scientists so far, most by the transit method. Twelve of those were found using NASA’s now-retired Kepler Space Telescope, the mission that takes the prize for the most transit detections (nearly 2,800). Scientists have observed a small number of debris disks and “protoplanetary” disks in polar orbits, and suspected that polar-orbiting planets might be out there as well. They seem at last to have turned one up.
The Discoverers
An international science team led by Thomas A. Baycroft, a Ph.D. student in astronomy and astrophysics at the University of Birmingham, U.K., published a paper describing their discovery in the journal “Science Advances” in April 2025. The planet was entered into NASA’s Exoplanet Archive on May 1, 2025. The system’s full name is 2MASS J15104786-281874 (2M1510 for short).
