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.

The Thin-Film Nuclear Engine Rocket (TFINER) is a novel space propulsion technology that enables aggressive space exploration for missions that are impossible with existing approaches. The concept uses thin layers of energetic radioisotopes to directly generate thrust. The emission direction of its natural decay products is biased by a substrate to accelerate the spacecraft. A single stage design is very simple and can generate velocity changes of ~100 km/s using a few kilograms of fuel and potentially more than 150 km/s for more advanced architectures.
The propulsion system enables a rendezvous with intriguing interstellar objects such as ‘Oumuamua that are on hyperbolic orbits through our solar system. A particular advantage is the ability to maneuver in deep space to find objects with uncertainty in their location. The same capabilities also enable a fast trip to the solar gravitational focus to image multiple potentially habitable exoplanets. Both types of missions require propulsion outside the solar system that is an order of magnitude beyond the performance of existing technology. The phase 2 effort will continue to mature TFINER and the mission design. The program will work towards small scale thruster experiments in the near term. In parallel, isotope production paths that can also be leveraged for other space exploration and medical applications will be pursued. Finally, advanced architectures such as an Oberth solar dive maneuver and hybrid approaches that leverage solar sails near the Sun, will be explored to enhance mission performance.

NASA Langley highlights its Cirrus Design SR22 during Air Power Over Hampton Roads STEM Day. NASA/Angelique Herring NASA Langley Research Center’s integral role in the past, present, and future of flight was on full display April 25-27 during the Air Power Over Hampton Roads air show.
The air show, held at Joint Base Langley-Eustis (JBLE), which neighbors NASA Langley in Hampton, Virginia, attracted thousands of spectators throughout the weekend.
The weekend kicked off with a STEM Day on April 25. Langley’s Office of STEM Engagement (OSTEM) offered educational and engaging activities, exhibits, and displays to share NASA missions and encourage K-12 students from local schools to explore the possibilities that science, technology, engineering, and math offer.
“Participation in the air show allows us to share NASA’s work in aeronautics with the public and provides an opportunity for Langley researchers and engineers to work directly with students and families to share the exciting work they do,” said Bonnie Murray, Langley OSTEM Student Services manager.

By observing flight of the plane designs and making improvements to each one, students participated in the engineering design process. NASA subject matter experts in attendance guided students through these activities, inspired young minds by sharing some of their innovations, and promoted a variety of STEM career paths.
“Through engagement in the NASA STEM Zone activities, students had an opportunity to see themselves in the role of a NASA researcher,” Murray said. “Authentic learning experiences such as these help build children’s STEM identity, increasing the likelihood of them pursuing STEM careers in the future.”

“Reflective of our strong, long-standing partnership with JBLE, NASA Langley was proud to participate in this year’s Air Power Over Hampton Roads air show,” said Glenn Jamison, director of Langley’s Research Services Directorate. “Our relationship spans back to 1917 when NACA and Langley Field evolved together over formative years in aerodynamic research, sharing the airspace and facilities here in Hampton. Today, we continue our collaboration with JBLE in pursuing shared interests and finding innovative solutions to complex problems.”
The displays also featured several small Unmanned Aircraft Systems (sUAS) and NASA’s P-3 Orion, a research aircraft based at NASA’s Wallops Flight Facility on Wallops Island, Virginia.
Air show visitors could explore a picture display that highlighted NASA Langley’s rich aviation legacy, from its founding in 1917 to Langley’s work today to accelerate advancements in aeronautics, science, and space technology and exploration. Spacey Casey, a crowd favorite, greeted and took pictures with educators, students, and guests throughout the weekend, bringing out-of-this-world smiles to their faces. Members of Langley’s Office of the Director also represented the center at the event.
