Years ago, physicist Dr. John Brandenburg stated that there is evidence of two nuclear explosions on Mars. These explosions could have been caused by thermonuclear bombs.
Remnants of an ancient city on Mars destroyed by thermonuclear attack.
Evidence supporting this theory includes the presence of nuclear isotopes in the Martian atmosphere and the detection of a thin layer of substances such as uranium, thorium, and radioactive potassium on the surface of Mars.
The absence of craters at the sites indicates that the bombs were likely detonated above ground in an air blast, which worsens the global fallout but dampens the immediate ground impact. Conversely, if detonated on the ground, the local devastation is immense but the global impact is minimized. Regardless, these explosions were powerful enough to cause a global catastrophe and significantly alter Mars' climate. According to Brandenburg, the nuclear attack apparently wiped out two races: the Cydonians and Utopians.
The MRO HiRISE image ESP_019103_1460 shows the "Atlantic Chaos," and a closer examination reveals a city that was almost destroyed by the thermonuclear explosions. Amid the ruins of destroyed buildings and towering structures, a largely intact dome-shaped structure is visible (See image below.)
The remnants of this city suggest that Mars was once inhabited by intelligent species like the Cydonians and Utopians, who lived there under conditions similar to those on Earth. This also serves as evidence that far more advanced civilizations may have existed for millions of years and possessed the capability to annihilate all life on a planet using thermonuclear bombs, among other means.

The Goldstone Solar System Radar, part of NASA’s Deep Space Network, made these observations of the recently discovered 500-foot-wide (150-meter-wide) asteroid 2024 MK, which made its closest approach — within about 184,000 miles (295,000 kilometers) of Earth — on June 29.NASA/JPL-Caltech The Deep Space Network’s Goldstone planetary radar had a busy few days observing asteroids 2024 MK and 2011 UL21 as they safely passed Earth.
Scientists at NASA’s Jet Propulsion Laboratory in Southern California recently tracked two asteroids as they flew by our planet. One turned out to have a little moon orbiting it, while the other had been discovered only 13 days before its closest approach to Earth. There was no risk of either near-Earth object impacting our planet, but the radar observations taken during these two close approaches will provide valuable practice for planetary defense, as well as information about their sizes, orbits, rotation, surface details, and clues as to their composition and formation.
Passing Earth on June 27 at a distance of 4.1 million miles (6.6 million kilometers), or about 17 times the distance between the Moon and Earth, the asteroid 2011 UL21 was discovered in 2011 by the NASA-funded Catalina Sky Survey, in Tucson, Arizona. But this is the first time it has come close enough to Earth to be imaged by radar. While the nearly mile-wide (1.5-kilometer-wide) object is classified as being potentially hazardous, calculations of its future orbits show that it won’t pose a threat to our planet for the foreseeable future.
Because close approaches by asteroids the size of 2024 MK are relatively rare, JPL’s planetary radar team gathered as much information about the near-Earth object as possible. This mosaic shows the spinning asteroid in one-minute increments about 16 hours after its closest approach with Earth.NASA/JPL-Caltech Using the Deep Space Network’s 230-foot-wide (70-meter) Goldstone Solar System Radar, called Deep Space Station 14 (DSS-14), near Barstow, California, JPL scientists transmitted radio waves to the asteroid and received the reflected signals by the same antenna. In addition to determining the asteroid is roughly spherical, they discovered that it’s a binary system: A smaller asteroid, or moonlet, orbits it from a distance of about 1.9 miles (3 kilometers).
“It is thought that about two-thirds of asteroids of this size are binary systems, and their discovery is particularly important because we can use measurements of their relative positions to estimate their mutual orbits, masses, and densities, which provide key information about how they may have formed,” said Lance Benner, principal scientist at JPL who helped lead the observations.
These seven radar observations by the Deep Space Network’s Goldstone Solar System Radar shows the mile-wide asteroid 2011 UL21 during its June 27 close approach with Earth from about 4 million miles away. The asteroid and its small moon (a bright dot at the bottom of the image) are circled in white.NASA/JPL-Caltech Second Close Approach
Two days later, on June 29, the same team observed the asteroid 2024 MK pass our planet from a distance of only 184,000 miles (295,000 kilometers), or slightly more than three-quarters of the distance between the Moon and Earth. About 500 feet (150 meters) wide, this asteroid appears to be elongated and angular, with prominent flat and rounded regions. For these observations, the scientists also used DSS-14 to transmit radio waves to the object, but they used Goldstone’s 114-foot (34-meter) DSS-13 antenna to receive the signal that bounced off the asteroid and came back to Earth. The result of this “bistatic” radar observation is a detailed image of the asteroid’s surface, revealing concavities, ridges, and boulders about 30 feet (10 meters) wide.
Close approaches of near-Earth objects the size of 2024 MK are relatively rare, occurring about every couple of decades, on average, so the JPL team sought to gather as much data about the object as possible. “This was an extraordinary opportunity to investigate the physical properties and obtain detailed images of a near-Earth asteroid,” said Benner.
This sunset photo shows NASA’s Deep Space Station 14 (DSS-14), the 230-foot-wide (70-meter) antenna at the Goldstone Deep Space Communications Complex near Barstow, California.NASA/JPL-Caltech The asteroid 2024 MK was first reported on June 16 by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) at Sutherland Observing Station in South Africa. Its orbit was changed by Earth’s gravity as it passed by, reducing its 3.3-year orbital period around the Sun by about 24 days. Although it is classified as a potentially hazardous asteroid, calculations of its future motion show that it does not pose a threat to our planet for the foreseeable future.
The Goldstone Solar System Radar Group is supported by NASA’s Near-Earth Object Observations Program within the Planetary Defense Coordination Office at the agency’s headquarters in Washington. Managed by JPL, the Deep Space Network receives programmatic oversight from Space Communications and Navigation program office within the Space Operations Mission Directorate, also at NASA Headquarters.

The first CHAPEA mission crew members who have been living and working inside NASA’s first simulated yearlong Mars habitat mission are set to exit their ground-based home on Saturday, July 6. The four volunteers who have been living and working inside NASA’s first simulated yearlong Mars habitat mission are set to exit their ground-based home on Saturday, July 6. NASA will provide live coverage of the crew’s exit from the habitat at NASA’s Johnson Space Center in Houston at 5 p.m. EDT.
NASA will stream the activity, which will include a short welcome ceremony, on NASA+, NASA Television, the NASA app, the agency’s website, and NASA Johnson’s X and Facebook accounts. Learn how to stream NASA TV through a variety of platforms, including social media.
The first Crew Health and Performance Exploration Analog (CHAPEA) mission began in the 3D printed habitat on June 25, 2023, with crew members Kelly Haston, Anca Selariu, Ross Brockwell, and Nathan Jones. For more than a year, the crew simulated Mars mission operations, including “Marswalks,” grew and harvested several vegetables to supplement their shelf-stable food, maintained their equipment and habitat, and operated under additional stressors a Mars crew will experience, including communication delays with Earth, resource limitations, and isolation.
In addition to the CHAPEA crew, participants include:
Steve Koerner, deputy director, NASA Johnson Kjell Lindgren, NASA astronaut and deputy director, Flight Operations Grace Douglas, principal investigator, CHAPEA Judy Hayes, chief science officer, Human Health and Performance Directorate Julie Kramer White, director of engineering Due to facility limitations and crew quarantine requirements, NASA is unable to accommodate requests to attend the event in person. Media interested in speaking with the mission’s crew members in the days following the conclusion of their mission must send a request by 4 p.m. July 6, to the Johnson newsroom at 281-483-5111 or jsccommu@nasa.gov.
NASA is leading a return to the Moon for long-term science and exploration through the Artemis campaign. Lessons learned on and around the Moon will prepare NASA for the next giant leap – sending the first astronauts to Mars.
