On January 25, 2025, an Oklahoma City man recorded a baffling UFO that he described as a "plasma-filled jellybean." A concerned neighbor also spotted something unusual in the sky and soon, the entire neighborhood gathered outside, to witness the anomaly.
The mysterious object emitted a glow and moved erratically, mesmerizing onlookers. In his recorded footage, Frederick can be heard narrating the event. "I don’t hear anything, and it's moving unpredictably," he noted. "It looks like a jellybean, but the interior appears to be plasma."
Frederick decided to launch his drone for a closer look, but upon attempting to deploy his drone, he encountered unexplained technical failures. "My controller provides voice notifications," he explained. "It repeatedly announced, ‘unable to take off, electromagnetic interference."
After multiple attempts, he finally got the drone airborne, reaching approximately 1,000 feet beneath the UFO. However, just after capturing three images, the drone’s video function failed, and its battery, despite being fully charged, suddenly drained. "It had a 35-minute flight time," Frederick stated. "But right after taking those three pictures, the controller alerted me: ‘low battery, return to home."
Seeking expert insight, Frederick shared his footage and images with University of Oklahoma physics professor Mukremin Kilic. When asked about the sighting, Kilic remarked, "I don’t know what it is" and suggested the object was likely a drone. However, this theory does not explain why Frederick’s own drone experienced interference, raising further questions about the true nature of the UFO.

On Feb. 11, 2000, space shuttle Endeavour took to the skies on its 14th trip into space on the Shuttle Radar Topography Mission (SRTM). The international STS-99 crew included Commander Kevin Kregel, Pilot Dominic Gorie, and Mission Specialists Gerhard Thiele of Germany representing the European Space Agency, Janet Kavandi, Janice Voss, who served as payload commander on the mission, and Mamoru Mohri of the National Space Development Agency (NASDA) of Japan, now the Japan Aerospace Exploration Agency.
During their 11-day mission, the astronauts used the radar instruments in Endeavour’s payload bay to obtain elevation data on a near global scale. The data produced the most complete, high-resolution digital elevation model of the Earth. The SRTM comprised a cooperative effort among NASA with the Jet Propulsion Laboratory (JPL) in Pasadena, California, managing the project, the Department of Defense’s National Imagery and Mapping Agency, the German space agency, and the Italian space agency. Prior to SRTM, scientists had a more detailed topographic map of Venus than of the Earth, thanks to the Magellan radar mapping mission.

NASA assigned the STS-99 crew in October 1998. For Kregel, selected by NASA as an astronaut in 1992, STS-99 marked his fourth trip to space, having served as pilot on STS-70 and STS-78 and commanded STS-87. Gorie and Kavandi, both selected in 1994, previously flew together as pilot and mission specialist, respectively, on STS-91, the final Shuttle Mir docking mission. Voss, selected in 1990, served as a mission specialist on STS-57 and STS-63, and as payload commander on STS-83 and STS-94. NASDA selected Mohri as an astronaut in 1985 and he previously flew as a payload specialist on STS-47, the Spacelab-J mission. Selected as an astronaut by the German space agency in 1987, Thiele joined the European Astronaut Corps in 1998, completing his first spaceflight on STS-99.
The SRTM used an innovative technique called radar interferometry to image the Earth’s landmasses at resolutions up to 30 times greater than previously achieved. Two of the synthetic aperture radar instruments comprising the SRTM payload had flown previously, on the STS-59 Shuttle Radar Laboratory-1 (SRL-1) and the STS-68 SRL-2 missions in April and October 1994, respectively. A second receiver antenna, placed at the end of a 200-foot deployable mast, enabled the interferometry during SRTM.

Workers rolled Endeavour to the Vehicle Assembly Building on Dec. 2 for mating with its external tank and solid rocket boosters, and then out to Launch Pad 39A on Dec. 13. The astronauts traveled to Kennedy to participate in the Terminal Countdown Demonstration Test Jan. 11-14, returning afterwards to Houston for final training. They traveled back to Kennedy on Jan. 27 for the first launch attempt four days later. After two launch attempts, the STS-99 mission prepared to liftoff on Feb. 11, 2000.
Liftoff! Space shuttle Endeavour takes to the skies to begin the STS-99 mission. At 12:43 p.m. EST, Endeavour thundered into the sky from Kennedy’s Launch Pad 39A to begin the STS-99 mission. Thirty-seven minutes later, a brief firing of the orbiter’s two engines placed Endeavour in the proper 145-mile orbit for the radar scanning.

Astronauts Kevin Kregel, left, and Gerhard Thiele on Endeavour’s flight deck. Shortly after reaching orbit, the crew opened the payload bay doors and deployed the shuttle’s radiators. Kavandi and Thiele turned on the instruments, deployed the 200-foot mast, and conducted initial checkouts of the radars. The crew split into two shifts to enable data collection around the clock during the mission. After overseeing the initial activation of the radars, the red shift of Kregel, Kavandi, and Thiele began their first sleep period as the blue shift of Gorie, Voss, and Mohri picked up with activation and began the first data takes.
The major crew activity for SRTM involved changing tapes every 30 minutes. The SRTM generated 332 high density tapes during more than 222 hours of data collection and these recordings covered 99.96 percent of the planned observations. Data collection finished on the mission’s 10th flight day, after which the astronauts reeled the mast back into its container in the payload bay.

NASA’s EarthKAM program enabled middle school students to remotely take photographs of the Earth using an electronic still camera mounted in one of the shuttle’s windows. The University of California at San Diego houses the control center for EarthKAM, linked with middle schools via the Internet. Students choose Earth targets of interest, and the camera takes photos of that region as the shuttle passes overhead. A then-record 75 schools from around the world participated in the EarthKAM project on STS-99, the camera returning 2,715 images of the Earth.
The STS-99 astronauts also spent time taking photographs of the Earth using handheld cameras and the high inclination orbit enabled views of some parts of the Earth rarely seen by shuttle astronauts.

NASA’s UAVSAR airborne radar instrument captured data in fall 2024 showing the mo-tion of landslides on the Palos Verdes Peninsula following record-breaking rainfall in Southern California in 2023 and another heavy-precipitation winter in 2024. Darker red indicates faster motion.NASA Earth Observatory Analysis of data from NASA radar aboard an airplane shows that the decades-old active landslide area on the Palos Verdes Peninsula has expanded.
Researchers at NASA’s Jet Propulsion Laboratory in Southern California used data from an airborne radar to measure the movement of the slow-moving landslides on the Palos Verdes Peninsula in Los Angeles County. The analysis determined that, during a four-week period in the fall of 2024, land in the residential area slid toward the ocean by as much as 4 inches (10 centimeters) per week.
Portions of the peninsula, which juts into the Pacific Ocean just south of the city of Los Angeles, are part of an ancient complex of landslides and has been moving for at least the past six decades, affecting hundreds of buildings in local communities. The motion accelerated, and the active area expanded following record-breaking rainfall in Southern California in 2023 and heavy precipitation in early 2024.
To create this visualization, the Advanced Rapid Imaging and Analysis (ARIA) team used data from four flights of NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) that took place between Sept. 18 and Oct. 17. The UAVSAR instrument was mounted to a Gulfstream III jet flown out of NASA’s Armstrong Flight Research Center in Edwards, California, and the four flights were planned to estimate the speed and direction of the landslides in three dimensions.
In the image above, colors indicate how fast parts of the landslide complex were moving in late September and October, with the darkest reds indicating the highest speeds. The arrows represent the direction of horizontal motion. The white solid lines are the boundaries of the active landslide area as defined in 2007 by the California Geological Survey.
“In effect, we’re seeing that the footprint of land experiencing significant impacts has expanded, and the speed is more than enough to put human life and infrastructure at risk,” said Alexander Handwerger, the JPL landslide scientist who performed the analysis.
The insights from the UAVSAR flights were part of a package of analyses by the ARIA team that also used data from ESA’s (the European Space Agency’s) Copernicus Sentinel-1A/B satellites. The analyses were provided to California officials to support the state’s response to the landslides and made available to the public at NASA’s Disaster Mapping Portal.
Handwerger is also the principal investigator for NASA’s upcoming Landslide Climate Change Experiment, which will use airborne radar to study how extreme wet or dry precipitation patterns influence landslides. The investigation will include flights over coastal slopes spanning the California coastline.
More About ARIA, UAVSAR
The ARIA mission is a collaboration between JPL and Caltech, which manages JPL for NASA, to leverage radar and optical remote-sensing, GPS, and seismic observations for science as well as to aid in disaster response. The project investigates the processes and impacts of earthquakes, volcanoes, landslides, fires, subsurface fluid movement, and other natural hazards.
UAVSAR has flown thousands of radar missions around the world since 2007, studying phenomena such as glaciers and ice sheets, vegetation in ecosystems, and natural hazards like earthquakes, volcanoes, and landslides.

The award, signed by President Biden, is the highest honor the federal government can grant to a federal civilian employee.
NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy presented Cabana with the award during a ceremony at NASA Headquarters in Washington on Jan. 10. Cabana most recently served as NASA’s associate administrator, which is the agency’s highest ranking civil servant, from 2021 until he retired from the agency at the end of 2023.
“A true public servant, Bob has spent his entire career in service to his country. I can think of no one more deserving of this rare honor than Bob,” said Nelson. “From his time as a naval aviator to his role as associate administrator of NASA, Bob has dedicated his life to improving his country. I join with President Biden in thanking Bob for his dedication and commitment.”
The award recognized Cabana for his roles as a Marine aviator, test pilot, astronaut and becoming the first American to enter the International Space Station. He was further recognized for continuing to push for the bounds of the possible, launching the James Webb Space Telescope, the Artemis I mission and the Orion spacecraft which will send humans back to the Moon for the first time in decades.
As a NASA astronaut, Cabana flew in space four times, including twice as commander. His final space shuttle flight in 1998 was the first International Space Station assembly mission. Cabana also was the director of the agency’s Kennedy Space Center in Florida for more than a decade. There he led its transition from retirement of the space shuttle to a multi-user spaceport once again launching NASA astronauts to low Earth orbit, and for the first time, doing so with commercial partners.
As NASA associate administrator, Cabana led the agency’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters. He was the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion.
Cabana was selected as an astronaut candidate in June 1985 and completed training in July 1986. He logged 38 days in space during four shuttle missions. Cabana was a pilot aboard space shuttle Discovery on both the STS-41 mission in October 1990 that deployed the Ulysses spacecraft and the STS-53 mission in December 1992. He was the mission commander aboard space shuttle Columbia for the STS-65 mission in July 1994 that conducted experiments as part of the second International Microgravity Laboratory mission. He commanded space shuttle Endeavour for the STS-88 mission in December 1998.
Cabana was appointed a member of the Federal Senior Executive Service in 2000 and served in numerous senior management positions at NASA’s Johnson Space Center in Houston, ultimately becoming deputy director. He was named director of NASA’s Stennis Space Center in Mississippi in October 2007 and a year later was selected as NASA Kennedy director.
Born in Minneapolis, Cabana graduated from the U.S. Naval Academy in 1971 with a bachelor’s degree in mathematics. He became a naval aviator and graduated with distinction from the U.S. Naval Test Pilot School in 1981. In his career, Cabana logged over 7,000 hours in more than 50 different kinds of aircraft. He retired as a colonel from the U.S. Marine Corps in September 2000.
In addition to receiving the President’s Award for Distinguished Federal Service, Cabana’s accomplishments have been recognized with induction into the Astronaut Hall of Fame and being named an Associate Fellow in the American Institute of Aeronautics and Astronautics and a Fellow in the Society of Experimental Test Pilots. He has received numerous personal awards and decorations, including the Distinguished Flying Cross and the Presidential Distinguished Rank Award. He also is a recipient of the Rotary National Award for Space Achievement’s National Space Trophy.
