The space shuttle Discovery launches from NASA’s Kennedy Space Center in Florida, heading through Atlantic skies toward its 51-D mission. The seven-member crew lifted off at 8:59 a.m. ET, April 12, 1985.NASA The launch of space shuttle Discovery is captured in this April 12, 1985, photo. This mission, STS-51D, was the 16th flight of NASA’s Space Shuttle program, and Discovery’s fourth flight.
Discovery carried out 39 missions, more than any other space shuttle. Its missions included deploying and repairing the Hubble Space Telescope and 13 flights to the International Space Station – including the very first docking in 1999. The retired shuttle now resides at the National Air and Space Museum’s Steven F. Udvar-Hazy Center in Virginia.

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

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Students from Universidad Católica Boliviana “San Pablo” compete during NASA’s 2024 Human Exploration Rover Challenge. The 2025 competition takes place Friday and Saturday, April 11-12, 2025, at the U.S. Space & Rocket Center’s Aviation Challenge course in Huntsville, Alabama. NASA NASA’s annual Human Exploration Rover Challenge returns Friday, April 11, and Saturday, April 12, with student teams competing at the U.S. Space & Rocket Center’s Aviation Challenge course near the agency’s Marshall Space Flight Center in Huntsville, Alabama.
Media are invited to watch as hundreds of students from around the world attempt to navigate a complex obstacle course by piloting a vehicle of their own design and production. Media interested in attending or setting up interviews should contact Taylor Goodwin in the Marshall Office of Communications at 938-210-2891 no later than 2 p.m. Thursday, April 10.
In addition to the traditional human-powered rover division, this year’s competition expands the challenge to include a remote-control division. The 2025 HERC Handbook includes guidelines for the new remote-control division and updates for the human-powered division.
Participating teams represent 35 colleges and universities, 38 high schools, and two middle schools from 20 states, Puerto Rico, and 16 other nations.
The event is free and open to the public, with rover excursions from 7:30 a.m. to 3 p.m. CDT each day, or until the last rover completes the obstacle course.
Following the competition, NASA will host an in-person awards ceremony Saturday, April 12, at 5:30 p.m. inside the Space Camp Operations Center at the U.S. Space & Rocket Center. NASA and industry sponsors will present multiple awards highlighting team successes throughout the past eight-months-long engineering design project, including awards for best rover design, best pit crew, best social media presence, and many other accomplishments.
About the Challenge
Recognized as NASA’s leading international student challenge, the Human Exploration Rover Challenge aims to put competitors in the mindset of NASA’s Artemis campaign. Teams pitch an engineering design for a lunar rover which simulates astronauts exploring the lunar surface while overcoming various obstacles. Eligible teams compete to be among the top three finishers in their divisions, and to win multiple awards, including best vehicle design, best rookie team, and more.
The annual challenge draws hundreds of students from around the world and reflects the goals of NASA’s Artemis campaign, which will establish the first long-term presence on the Moon and pave the way for eventual missions to Mars.
The event was launched in 1994 as the NASA Great Moonbuggy Race – a collegiate competition to commemorate the 25th anniversary of the Apollo 11 lunar landing. It expanded in 1996 to include high school teams, evolving again in 2014 into the NASA Human Exploration Rover Challenge. Since its inception, more than 15,000 students have participated – with many former students now working in the aerospace industry, including with NASA.
The Human Exploration Rover Challenge is managed by NASA Marshall’s Southeast Regional Office of STEM Engagement and is one of eight Artemis Student Challenges. NASA’s Office of STEM Engagement uses challenges and competitions to further the agency’s goal of encouraging students to pursue degrees and careers in science, technology, engineering, and mathematics.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
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.
