      Several days ago, a massive blackout swept across large parts of Spain, Portugal, and parts of southern France. Millions were left without power as the interconnected European energy grid experienced a rare and abrupt failure. While authorities quickly pointed to a "rare atmospheric phenomenon" as the cause, not everyone is convinced. 

      Here are some explanations of authorities as well as controversial theories: 
      According to REN, Portugal’s national electricity grid operator, the blackout was triggered by a fault originating in Spain’s power infrastructure. The disruption, they claim, was linked to "induced atmospheric variation", a term referring to extreme temperature differences that led to anomalous oscillations in high-voltage transmission lines. These oscillations reportedly caused synchronization failures between regional grid systems, ultimately sparking a chain reaction of failures across the European network. 
      What makes the situation even more intriguing is that just days before the blackout, Spain hit a historic energy milestone. On April 16, for the first time, the country’s electricity demand was met entirely by renewable energy sources - solar, wind, and hydro, during a weekday. It raises questions whether the outage was caused by a technical failure of this new renewable energy system. 
      While this achievement is noteworthy, it also exposes the fragility of a grid increasingly reliant on variable energy sources, especially solar, which can fluctuate dramatically with weather and atmospheric conditions. 
      Despite official explanations, some experts and observers remain skeptical. There were no solar flares or geomagnetic storms in the days leading up to the blackout, and solar activity had been relatively calm. Critics argue that while atmospheric disturbances may have played a role, they are not sufficient to explain such a widespread, synchronized failure.
      Despite the fact that the blackout this time was probably not caused by solar flares or geomagnetic storms it has been proven that Earth’s magnetic shield is rapidly weakening, leaving us increasingly vulnerable to powerful solar storms. The magnetic north pole is accelerating toward Siberia, and the South Atlantic Anomaly continues to expand, ominous signs that a looming plasma event could bring consequences far beyond just technological disruption.
      This has led to speculation that the blackout could have been intentional, possibly even a test run for handling future crises or threats to infrastructure. 
      Among the more controversial theories is the suggestion that this event might have involved the use of a graphite bomb, a non-lethal weapon designed to disable power grids. These devices disperse ultra-fine carbon filaments into high-voltage power lines, causing short circuits by creating conductive paths between lines. Such an attack would appear as a grid malfunction but could be devastating in scale. 
      Another controversial theory is that the outage has been caused by weather manipulation systems such as HAARP or the Ice Cube Neutrino observatory, constructed at the Amundsen–Scott South Pole Station in Antarctica. 
      Could this have been a covert drill or a demonstration of vulnerability? Some point to global forums, such as the World Government Summit, where figures like Klaus Schwab have warned about Black Swan: An unpredictable event that is beyond what is normally expected of a situation and has potentially severe consequences. 
      Whether the blackout was triggered by a rare natural event, a technical failure, or something more deliberate, it seems only a matter of time before we face a true Black Swan event. View the full article

      NASA astronaut and Expedition 72 Flight Engineer Don Pettit sets up camera hardware to photograph research activities inside the International Space Station’s Kibo laboratory module on March 15, 2025.Credit: NASA Media are invited to a news conference at 2 p.m. EDT Monday, April 28, at NASA’s Johnson Space Center in Houston where astronaut Don Pettit will share details of his recent mission aboard the International Space Station.
      The news conference will stream live on NASA’s website. Learn how to stream NASA content through a variety of platforms.
      To participate in person, U.S. media must contact the NASA Johnson newsroom no later than 5 p.m. Thursday, April 24, at 281-483-5111 or jsccommu@mail.nasa.gov. Media wishing to participate by phone must contact the newsroom no later than two hours before the start of the event. To ask questions by phone, media must dial into the news conference no later than 10 minutes prior to the start of the call. NASA’s media accreditation policy is available online.
      Questions also may be submitted on social media during the news conference by using #AskNASA. Following the news conference, NASA will host a live question and answer session with Pettit on the agency’s Instagram. For more information, visit @NASA on social media.
      Pettit returned to Earth on April 19 (April 20, Kazakhstan time), along with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. Pettit celebrated his 70th birthday on April 20. He spent 220 days in space as an Expedition 71/72 flight engineer, bringing his career total to 590 days in space during four spaceflights. Pettit and his crewmates completed 3,520 orbits of Earth over the course of their 93-million-mile journey. They also saw the arrival of six visiting spacecraft and the departure of seven.
      During his time on orbit, Pettit conducted hundreds of hours of scientific investigations, including research to enhance on-orbit metal 3D printing capabilities, advance water sanitization technologies, explore plant growth under varying water conditions, and investigate fire behavior in microgravity, all contributing to future space missions.
      He also spent time aboard the space station sharing his photography, often posting images to his X account. He took more than 670,000 photos during his stay.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Astronauts Victor Glover and Christina Koch tour the Arc Jet Facility at NASA’s Ames Research Center, learning more about the testing equipment’s capabilities to analyze thermal protection systems from George Raiche, thermophysics facilities branch chief at Ames.NASA/Donald Richey As NASA prepares to send astronauts to the Moon aboard the Orion spacecraft, research, testing, and development at NASA’s Ames Research Center in California’s Silicon Valley has played a critical role.
      Recently, Ames welcomed Artemis II astronauts Christina Koch and Victor Glover and Orion leaders Debbie Korth, deputy program manager, and Luis Saucedo, deputy crew and service module manager, to tour Ames facilities that support the Orion Program and celebrate the achievements of employees.
      The group started their visit at the Arc Jet Complex, where researchers use extremely hot, high-speed gases to simulate the intense heat of atmospheric reentry before visiting the Sensors & Thermal Protection Systems Advanced Research Laboratories. The team works to develop sensors and flight instrumentation that measure heat shield response throughout a mission.
      These systems were used to develop and test Orion’s thermal protection system to ensure the safety of astronauts during future missions. After the successful return of the Artemis I Orion spacecraft, Ames research was essential when analyzing unexpected charring loss on the heat shield.
      Debbie Korth, Orion deputy program manager, presents awards to the Ames workforce at the Orion Circle of Excellence Awards Ceremony, while astronauts Christina Koch and Victor Glover look on.NASA/Donald Richey The visit culminated in an award ceremony to honor employees with outstanding performance and a legacy of service to the Orion Program. Thirty-two employees were honored for their individual or team contributions.
      “The Ames workforce has played an important role in developing, testing, and validating the Orion spacecraft’s thermal protection system as well as supporting its software and guidance, navigation, and control,” said Eugene Tu, NASA Ames center director. “I’m pleased to see their contributions recognized and celebrated by program leadership and two of the astronauts whose safety and success were in mind when ensuring these systems are safe, reliable, and the highest quality possible.”
