The aircraft is heading to the National POW/MIA Memorial and Museum in Jacksonville, Florida, where it will be on display, honoring all Prisoners of War (POW), those Missing in Action (MIA), and the families who seek the return of their loved ones. The museum gives visitors a place of solace to reflect, learn, and hear stories about America’s POW and MIA service members through exhibits and events.

The museum gets an aircraft in beautiful shape, and our S-3 gets to continue living a meaningful life.”
Originally designed by Lockheed Martin as an anti-submarine warfare aircraft, NASA’s S-3B Viking will travel south to its new museum home, which is located at the former Naval Air Station Cecil Field where S-3B Vikings once flew. It will be displayed with a plaque recognizing the 54 service members who perished during S-3 flight missions.

Behind the scenes, this S-3 supported vital NASA flight research by donating parts to its sister plane, another S3-B Viking that was retired in 2021. Through the donation of its parts, the S-3 contributed to communications research in advanced air mobility and monitoring of algal bloom growth in Lake Erie.
“Having this aircraft added an extra 10 years of life to its sister plane,” Demers said. “Those 10 years were vital for research. This plane allowed us to keep flying that aircraft after the Navy retired the S-3B Vikings in 2009. We wouldn’t have been able to find parts.”

There were S-3B Vikings in all locations except Jacksonville, until now.
“There are three bases in three locations that used to fly S-3s, and now each area has an S-3 as part of its display,” Demers said. “It belongs there. It’s going back to its original home.”

UVB-76, widely known by its nickname "The Buzzer," is a mysterious shortwave Russian radio station radio broadcasts in the world. It began broadcasting in the mid-1970s and is still active today, broadcasting cryptic signals at 4625 kHz.
This Russian shortwave station usual broadcast consists of a monotonous buzzing tone that occasionally breaks for cryptic voice messages in Russian. The station is widely believed to be operated by the Russian military, possibly as part of the Strategic Rocket Forces’ communication network.
The use of shortwave radio enables the signal to travel vast distances, potentially covering all of Russia and extending far beyond its borders.
Due to the high transmission power of UVB-76’s antenna, some theorize that the station’s signals could even reach outer space. This possibility opens the door to even more extraordinary speculation: that satellites might receive these signals and relay them to submarines, remote military units, or even unidentified aerial phenomena (UFOs). One theory even posits that UVB-76 could be part of an experimental system designed to scan or communicate with extraterrestrial life.
Under normal circumstances, UVB-76’s broadcasts are infrequent and minimal, just the repetitive buzz and the rare coded message. However, something highly unusual happened just ten hours ago. Within a single day, the station transmitted four coded voice messages, an event considered extremely rare and potentially significant.
These are the messages: NZHTI - 33 702 - NEPTUN - 66-52-20-75 NZHTI - 8002 361 - TIMUS - 56-85 NZHTI - 7000 0 8002 - LISOPLASH - 67-203-0808-0809 NZHTI - 62 505 - NUTOBAKS - 78 15 92 71
While the true meaning of these messages remains classified or unknown, some analysts believe they could be activation codes, operational signals, or test messages for military units. The repeated prefix "NZHTI" could be a call sign or an authentication marker. The names—NEPTUN, TIMUS, LISOPLASH, and NUTOBAKS, might refer to code-named operations, geographic regions, or military assets. The numeric sequences could represent coordinates, timestamps, or identification numbers.
Given the timing and unusual frequency of these messages, some suspect that UVB-76 is ramping up activity in preparation for a significant event. While there's no confirmation of any immediate threat, the sudden uptick in coded communications suggests that something serious could be developing.
Many experts believe UVB-76 is maintained as a wartime contingency channel, ready to relay commands in the event of nuclear war or a catastrophic loss of national communications. Its consistent presence, even during peacetime, supports the theory that it serves as an emergency or fail-safe communication method for defense forces.
The sudden surge of messages within one day suggests that something serious is happening, or about to. But who are they intended for? And more importantly, what comes next?" View the full article

What are the dangers of going to space?
For human spaceflight, the first thing I think about is the astronauts actually strapping themselves to a rocket. And if that isn’t dangerous enough, once they launch and they’re out into space in deep exploration, we have to worry about radiation.
Radiation is coming at them from all directions. From the Sun, we have solar particles. We have galactic cosmic rays that are all over in the universe. And those cause damage to DNA. On Earth here, we use sunscreen to protect us from DNA damage. Our astronauts are protected from the shielding that’s around them in the space vehicles.
We also have to worry about microgravity. So what happens there? We see a lot of bone and muscle loss in our astronauts. And so to prevent this, we actually have the astronauts exercising for hours every day. And of course we don’t want to run out of food on a space exploration mission. So we want to make sure that we have everything that the astronauts need to take with them to make sure that we can sustain them.
There are many risks associated with human space exploration. NASA has been planning for these missions to make our astronauts return home safely.

This team from University High School in Irvine, California, won the 2025 regional Oceans Science Bowl, hosted by NASA’s Jet Propulsion Laboratory. From left: Nethra Iyer, Joanne Chen, Matthew Feng, Avery Hexun, Angelina Yan, and coach David Knight.NASA/JPL-Caltech The annual regional event puts students’ knowledge of ocean-related science to the test in a fast-paced academic competition.
A team of students from University High School in Irvine earned first place at a fast-paced regional academic competition focused on ocean science disciplines and hosted by NASA’S Jet Propulsion Laboratory in Southern California.
Eight teams from Los Angeles and Orange counties competed at the March 29 event, dubbed the Los Angeles Surf Bowl. It was the last of about 20 regional competitions held across the U.S. this year in the lead-up to the virtual National Ocean Sciences Bowl finals event in mid-May.
Santa Monica High School earned second place; Francisco Bravo Medical Magnet High School in Los Angeles came in third. With its victory, University repeated its winning performance from last year. The school also won the JPL-hosted regional Science Bowl earlier this month.
Teams from all eight schools that participated in the JPL-hosted 2025 regional Ocean Sciences Bowl pose alongside volunteers and coaches.NASA/JPL-Caltech For the Ocean Sciences Bowl, teams are composed of four to five students and a coach. To prepare for the event, team members spend months answering multiple-choice questions with a “Jeopardy!”-style buzzer in just five seconds. Questions come in several categories, including biology, chemistry, geology, and physics along with related geography, technology, history, policy, and current events topics.
A question in the chemistry category might be “What chemical is the principal source of energy at many of Earth’s hydrothermal vent systems?” (It’s hydrogen sulfide.) Other questions can be considerably more challenging.
When a team member buzzes in and gives the correct answer to a multiple-choice question, the team earns a bonus question, which allows teammates to consult with one another to come up with an answer. More complicated “team challenge questions” prompt students to work together for a longer period. The theme of this year’s competition is “Sounding the Depths: Understanding Ocean Acoustics.”
University High junior Matthew Feng, a return competitor, said the team’s success felt like a payoff for hours of studying together, including on weekends. He keeps coming back to the competition partly for the sense of community and also for the personal challenge, he said. “It’s nice to compete and meet people, see people who were here last year,” Matthew added. “Pushing yourself mentally — the first year I was shaking so hard because I wasn’t used to that much adrenaline.”
Since 2000, JPL’s Public Services Office has coordinated the Los Angeles regional contest with the help of volunteers from laboratory staff and former Ocean Sciences Bowl participants in the local community. JPL is managed for NASA by Caltech.
The National Ocean Sciences Bowl is a program of the Center for Ocean Leadership at the University Corporation for Atmospheric Research, a nonprofit consortium of colleges and universities focused in part on Earth science-related education.
