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

Why do we grow plants in space?
Plants are such versatile organisms that they can fulfill many roles in our exploration of space. Plants provide us with food, with oxygen, they can recycle water and waste, and they can even provide us with psychological benefits. So all these functions will help NASA in fulfilling our goal of trying to create a sustainable environment for human presence in space.
But there are also other benefits. We can investigate how plants adapt to the novel environment of space, something that’s completely outside their evolutionary history. We can develop new processes and technologies to cultivate plants in difficult and even extreme environments. All these lessons learned will help us in ultimately improving the lives of humans here on Earth by being able to better cultivate plants.
So why do we grow plants in space? To be able to create a sustainable environment for us to thrive in space, as well as improve lives and agricultural techniques here on Earth.

Video: 00:02:14 On 12 March 2025, ESA’s Hera spacecraft soared just 5000 km above Mars and passed within 300 km of its distant moon, Deimos. Captured by Hera’s 1020x1020 pixel Asteroid Framing Camera, this video sequence offers a rare view of the red planet and its enigmatic moon. The original greyscale images have been colour-enhanced based on known surface features.
