Who built this underwater base 600 km off the coast of Antarctica? 

underwater%20ufo%20base%20antarctica.jpg

The base is approximately 700 x 500 meters with a solid structure of approximately 320x320x160 meters on top. 

The base also includes a landing platform, porthole, and building structure below the landing platform.

Could there be a connection between this base and the unexplained UFO activity around and over Antarctica? 

Coordinates: 72°2'38.19"S 162°55'41.45"W

      Flight Engineer Joe Acaba works in the U.S. Destiny laboratory module on the International Space Station, setting up hardware for the Zero Boil-Off Tank (ZBOT) experiment. Joe Acaba Space missions rely on cryogenic fluids — extremely cold liquids like liquid hydrogen and oxygen — for both propulsion and life support systems. These fuels must be kept at ultra-low cryogenic temperatures to remain in liquid form; however, solar heating and other sources of heat increase the rate of evaporation of the liquid and cause the pressure in the storage tank to increase. Current storage methods require venting the cryogenic propellant to space to control the pressure in fuel tanks.
      NASA’s Zero Boil-Off Tank Noncondensables (ZBOT-NC) experiment is the continuation of Zero Boil-Off studies gathering crucial data to optimize fuel storage systems for space missions. The experiment will launch aboard Northrop Grumman’s 23rd resupply mission to the International Space Station.
      When Cold Fuel Gets Too Warm
      Even with multilayer insulation, heat unavoidably seeps into cryogenic fuel tanks from surrounding structures and the space environment, causing an increase in the liquid temperature and an associated increase in the evaporation rate. In turn, the pressure inside the tank increases. This process is called “boil-off” and the increase in tank pressure is referred to as “self-pressurization.”
      Venting excess gas to the environment or space when this process occurs is highly undesirable and becomes mission-critical on extended journeys. If crew members used current fuel storage methods for a years-long Mars expedition, all propellant might be lost to boil-off before the trip ends.
      NASA’s ZBOT experiments are investigating active pressure control methods to eliminate wasteful fuel venting. Specifically, active control through the use of jet mixing and other techniques are being evaluated and tested in the ZBOT series of experiments.
      The Pressure Control Problem
      ZBOT-NC further studies how noncondensable gases (NCGs) affect fuel tank behavior when present in spacecraft systems. NCGs don’t turn into liquid under the tank’s operating conditions and can affect tank pressure.
      The investigation, which is led out of Glenn Research Center, will operate inside the Microgravity Science Glovebox aboard the space station to gather data on how NCGs affect volatile liquid behavior in microgravity. It’s part of an effort to advance cryogenic fluid management technologies and help NASA better understand low-gravity fluid behavior.
      Researchers will measure pressure and temperature as they study how these gases change evaporation and condensation rates. Previous studies indicate the gases create barriers that could reduce a tank’s ability to maintain proper pressure control — a potentially serious issue for extended space missions.
      How this benefits space exploration
      The research directly supports Mars missions and other long-duration space travel by helping engineers design more efficient fuel storage systems and future space depots. The findings may also benefit scientific instruments on space telescopes and probes that rely on cryogenic fluids to maintain the extremely low temperatures needed for operation.
      How this benefits humanity
      The investigation could improve tank design models for medical, industrial, and energy production applications that depend on long-term cryogenic storage on Earth.

      Three U.S. military veterans, two from the Air Force and one from the Navy, took the stand Tuesday during the third congressional hearing on Unidentified Anomalous Phenomena (UAPs), the government’s sanitized new term for UFOs. 

      The most shocking moment came when Congressman Eric Burlison of Missouri unveiled never before seen military footage: a U.S. drone firing a hellfire missile at a mysterious object off the coast of Yemen on October 30, 2024. 
      The grainy black and white video shows the 100 pound precision weapon streaking toward the target, only to ricochet off harmlessly as the object shot away at impossible speed. Just as baffling, three smaller spheres hovered in formation around the craft, undisturbed by the impact.  
      Reactions were mixed. Skeptics immediately dismissed the video, claiming it could be nothing more than a misidentified balloon, its apparent speed exaggerated by the drone’s telephoto lens. Others suggested the missile was part of a weapons test rather than a failed strike on something otherworldly. 
      But the testimony didn’t stop with the video. Two veterans alleged the government has been actively silencing witnesses, threatening those who came forward, and even blacklisting service members who refused to stay quiet. Dylan Borland, a former Air Force geospatial intelligence specialist, testified that multiple agencies conspired to destroy his career blocking jobs, forging documents, and tampering with his security clearance. 
      For some, this hearing represented a breakthrough in UFO transparency. For others, it was little more than political theater. As one observer put it: it looks like it is just another carefully staged distraction, the UFO spectacle might just be a smokescreen for something deeper.

      The first video, beginning around the 1:02 mark, was captured on a dash cam while driving eastbound on a four-lane freeway. Suddenly, a large triangular craft entered the frame, flying approximately 300 to 400 feet above the road. 

      Although the exact location remains unknown, the sighting is remarkable for its level of visible detail: 
      A blinking light with two dull orange lights in the center. A large circular feature on the underside, possibly an energy source. A distinctly aerodynamic triangular design. What appears to be an energy field or interference surrounding the craft. An estimated width of 75 to 100 feet, with no audible sound, suggesting non-conventional technology. 
      When viewed in slow motion, the footage stands out as one of the most striking nighttime captures to date, raising the question: is this a black-budget military project, or evidence of something extraterrestrial? Interestingly, the triangular craft bears a strong resemblance to the rumored TR-3B black manta, an alleged anti-gravity alien reproduction vehicle. 
      Additional almost similar sightings in Texas and Florida. 
      Austin, Texas: A dark craft hovering silently in the night sky, completely stationary throughout the entire recording. Sarasota, Florida: Three energy sources forming a triangular pattern while hovering in the night sky. It looks like it could be one of those triangle crafts. 
      Today, many aerial craft, whether human-made or not, are observed using technologies that remain beyond our current understanding.

      NASA’s 1991 Discovery shuttle video shows UFOs making impossible maneuvers, evading a possible Star Wars railgun test. Evidence of secret tech? 

      In September 1991, NASA’s Space Shuttle Discovery transmitted live video that has since become one of the most debated UFO clips ever recorded. The footage, later analyzed by independent researchers, shows glowing objects in orbit performing maneuvers far beyond the limits of known physics. 
      One object appears over Earth’s horizon, drifts smoothly, then suddenly reacts to a flash of light by accelerating at impossible speeds, estimated at over 200,000 mph while withstanding forces of 14,000 g’s. NASA officially dismissed the anomalies as ice particles or debris, but side by side comparisons with actual orbital ice show key differences: the objects make sharp turns, sudden accelerations, and fade in brightness in ways consistent with being hundreds of miles away, not near the shuttle. 
      Image analysis expert Dr. Mark Carlotto confirmed that at least one object was located about 1,700 miles from the shuttle, placing it in Earth’s atmosphere. At that distance, the object would be too large and too fast to be dismissed as ice or space junk. 
      The flash and two streaks seen in the video resemble the Pentagon’s “Brilliant Pebbles” concept, a railgun based missile defense system tested in the early 1990s. Researchers suggest the shuttle cameras may have accidentally, or deliberately, captured a live Star Wars weapons test in orbit. 
      The UFO easily evaded the attack, leading some to conclude that it was powered by a form of hyperdimensional technology capable of altering gravity. 
      Notably, following this 1991 incident, all subsequent NASA shuttle external camera feeds were censored or delayed, raising speculation that someone inside the agency allowed the extraordinary footage to slip out.

      The SpaceX Crew Dragon Endurance spacecraft is seen as it lands with NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov aboard in the Pacific Ocean off the coast of San Diego, Saturday, Aug. 9, 2025.Credit: NASA/Keegan Barber The first crew to splash down in the Pacific Ocean off the coast of California as part of NASA’s Commercial Crew Program completed the agency’s 10th commercial crew rotation mission to the International Space Station on Saturday.
      NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov returned to Earth at 11:33 a.m. EDT. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew. After returning to shore, the crew will fly to NASA’s Johnson Space Center in Houston and reunite with their families.
      “Splashdown! Crew-10 is back on Earth from the International Space Station marking the completion of another successful flight,” said NASA acting Administrator Sean Duffy. “Our crew missions are the building blocks for long-duration, human exploration pushing the boundaries of what’s possible. NASA is leading the way by setting a bold vision for exploration where we have a thriving space industry supporting private space stations in low Earth orbit, as well as humans exploring the Moon and Mars.”
      The agency’s SpaceX Crew-10 mission lifted off at 7:03 p.m. on March 14, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. About 29 hours later, the crew’s SpaceX Dragon spacecraft docked to the Harmony module’s space-facing port at 12:04 a.m. on March 16. Crew-10 undocked at 6:15 p.m. Aug. 8, to begin the trip home.
      During their mission, crew members traveled nearly 62,795,205 million miles and completed 2,368 orbits around Earth. The Crew-10 mission was the first spaceflight for Ayers and Peskov, and the second spaceflight for McClain and Onishi. McClain has logged 352 days in space over her two flights, and Onishi has logged 263 days in space during his flights.
      Along the way, Crew-10 contributed hundreds of hours to scientific research, maintenance activities, and technology demonstrations. McClain, Ayers, and Onishi completed investigations on plant and microalgae growth, examined how space radiation affects DNA sequences in plants, observed how microgravity changes human eye structure and cells in the body, and more. The research conducted aboard the orbiting laboratory advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.
      McClain and Ayers also completed a spacewalk on May 1, relocating a communications antenna, beginning the installation of a mounting bracket for a future International Space Station Roll-Out Solar Array, and other tasks. It was the third spacewalk for McClain, the first for Ayers, and the 275th supporting space station assembly, maintenance, and upgrades.
      Crew-10’s return to Earth follows the Crew-11 mission, which docked to the station on Aug. 2 for its long-duration science expedition.
      NASA’s Commercial Crew Program provides reliable access to space, maximizing the use of the International Space Station for research and development, and supporting future missions beyond low Earth orbit, such as to the Moon and Mars, by partnering with private U.S. companies, including SpaceX, to transport astronauts to and from the space station.
