Honolulu is pictured here beside a calm sea in 2017. A JPL technology recently detected and confirmed a tsunami up to 45 minutes prior to detection by tide gauges in Hawaii, and it estimated the speed of the wave to be over 580 miles per hour (260 meters per second) near the coast.NASA/JPL-Caltech A massive earthquake and subsequent tsunami off Russia in late July tested an experimental detection system that had deployed a critical component just the day before.
A recent tsunami triggered by a magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula sent pressure waves to the upper layer of the atmosphere, NASA scientists have reported. While the tsunami did not wreak widespread damage, it was an early test for a detection system being developed at the agency’s Jet Propulsion Laboratory in Southern California.
Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the experimental technology “functioned to its full extent,” said Camille Martire, one of its developers at JPL. The system flagged distortions in the atmosphere and issued notifications to subscribed subject matter experts in as little as 20 minutes after the quake. It confirmed signs of the approaching tsunami about 30 to 40 minutes before waves made landfall in Hawaii and sites across the Pacific on July 29 (local time).
“Those extra minutes of knowing something is coming could make a real difference when it comes to warning communities in the path,” said JPL scientist Siddharth Krishnamoorthy.
Near-real-time outputs from GUARDIAN must be interpreted by experts trained to identify the signs of tsunamis. But already it’s one of the fastest monitoring tools of its kind: Within about 10 minutes of receiving data, it can produce a snapshot of a tsunami’s rumble reaching the upper atmosphere.
The dots in this graph indicate wave disturbances in the ionosphere as measured be-tween ground stations and navigation satellites. The initial spike shows the acoustic wave coming from the epicenter of the July 29 quake that caused the tsunami; the red squiggle shows the gravity wave the tsunami generated.NASA/JPL-Caltech The goal of GUARDIAN is to augment existing early warning systems. A key question after a major undersea earthquake is whether a tsunami was generated. Today, forecasters use seismic data as a proxy to predict if and where a tsunami could occur, and they rely on sea-based instruments to confirm that a tsunami is passing by. Deep-ocean pressure sensors remain the gold standard when it comes to sizing up waves, but they are expensive and sparse in locations.
“NASA’s GUARDIAN can help fill the gaps,” said Christopher Moore, director of the National Oceanic and Atmospheric Administration Center for Tsunami Research. “It provides one more piece of information, one more valuable data point, that can help us determine, yes, we need to make the call to evacuate.”
Moore noted that GUARDIAN adds a unique perspective: It’s able to sense sea surface motion from high above Earth, globally and in near-real-time.
Bill Fry, chair of the United Nations technical working group responsible for tsunami early warning in the Pacific, said GUARDIAN is part of a technological “paradigm shift.” By directly observing ocean dynamics from space, “GUARDIAN is absolutely something that we in the early warning community are looking for to help underpin next generation forecasting.”
How GUARDIAN works
GUARDIAN takes advantage of tsunami physics. During a tsunami, many square miles of the ocean surface can rise and fall nearly in unison. This displaces a significant amount of air above it, sending low-frequency sound and gravity waves speeding upwards toward space. The waves interact with the charged particles of the upper atmosphere — the ionosphere — where they slightly distort the radio signals coming down to scientific ground stations of GPS and other positioning and timing satellites. These satellites are known collectively as the Global Navigation Satellite System (GNSS).
While GNSS processing methods on Earth correct for such distortions, GUARDIAN uses them as clues.
SWOT Satellite Measures Pacific Tsunami The software scours a trove of data transmitted to more than 350 continuously operating GNSS ground stations around the world. It can potentially identify evidence of a tsunami up to about 745 miles (1,200 kilometers) from a given station. In ideal situations, vulnerable coastal communities near a GNSS station could know when a tsunami was heading their way and authorities would have as much as 1 hour and 20 minutes to evacuate the low-lying areas, thereby saving countless lives and property.
Key to this effort is the network of GNSS stations around the world supported by NASA’s Space Geodesy Project and Global GNSS Network, as well as JPL’s Global Differential GPS network that transmits the data in real time.
The Kamchatka event offered a timely case study for GUARDIAN. A day before the quake off Russia’s northeast coast, the team had deployed two new elements that were years in the making: an artificial intelligence to mine signals of interest and an accompanying prototype messaging system.
Both were put to the test when one of the strongest earthquakes ever recorded spawned a tsunami traveling hundreds of miles per hour across the Pacific Ocean. Having been trained to spot the kinds of atmospheric distortions caused by a tsunami, GUARDIAN flagged the signals for human review and notified subscribed subject matter experts.
Notably, tsunamis are most often caused by large undersea earthquakes, but not always. Volcanic eruptions, underwater landslides, and certain weather conditions in some geographic locations can all produce dangerous waves. An advantage of GUARDIAN is that it doesn’t require information on what caused a tsunami; rather, it can detect that one was generated and then can alert the authorities to help minimize the loss of life and property.
While there’s no silver bullet to stop a tsunami from making landfall, “GUARDIAN has real potential to help by providing open access to this data,” said Adrienne Moseley, co-director of the Joint Australian Tsunami Warning Centre. “Tsunamis don’t respect national boundaries. We need to be able to share data around the whole region to be able to make assessments about the threat for all exposed coastlines.”

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.

Perseverance has continued exploring beyond the rim of Jezero crater, spending time last week at Parnasset conducting a mini-campaign on aeolian bedforms. After wrapping up that work, three separate drives brought Perseverance further southeast to an outcrop named Soroya.
Soroya was first picked out from orbital images as a target of interest because, as can be seen in the above image, it appears as a much lighter color compared to the surroundings. In previous landscape images from the surface, Mars 2020 scientists have been able to pick out the light-toned Soryoa outcrop, and they noted it forms a ridge-like structure, protruding above the surface. Soroya was easily identifiable from rover images (below) as Perseverance approached since it indeed rises above the surrounding low-lying terrain.
The Perseverance rover acquired this image looking at Soroya using the onboard Left Navigation Camera (Navcam). This image was acquired on Aug. 15, 2025 (Sol 1595) at the local mean solar time of 16:34:53. NASA/JPL-Caltech From Parnasset to Soroya, the team planned a series of drives so that Perseverance would arrive at Soroya in a great workspace, and the plan was successful. As shown in the first image, we arrived at an area with flat, exposed bedrock – great for proximity science instruments.
The WATSON and SHERLOC ACI cameras plan to acquire many high-resolution images to investigate textures and surface features. For chemistry, SCAM LIBS and ZCAM multispectral activities will give important contextual data for the outcrop while PIXL will acquire a high-resolution chemical map scan of a dust-cleared part of the bedrock. While parked, MEDA will continue monitoring environmental conditions and ZCAM will image the surrounding terrain to inform the next drive location. Take a look at where Perseverance is now – where would you explore next?

Preparations for Next Moonwalk Simulations Underway (and Underwater)
ResilienX employees Angelo Niforatos, left, and Ryan Pleskach, right, overview the NASA safety tools integrated into the company’s commercial system, July 11, 2025, at the ResilienX Headquarters in Syracuse, New York. Credit: ResilienX A future with advanced air mobility aircraft populating the skies will require the U.S. to implement enhanced preflight planning that can mitigate potential risks well before takeoff – and NASA is working to develop the tools to make that happen.
Preflight planning is critical to ensuring safety in the complex, high-risk environments of the future airspace. Timely, predictive, and up-to-date risk assessment within a single platform makes it much easier for drone or air taxi operators to check flight plans for high-risk concerns.
NASA is working on tools to deliver those services, and in June, the agency and aviation safety company ResilienX Inc. demonstrated how these tools can be integrated into commercial systems.
During a series of tests conducted at ResilienX’s facility in Syracuse, New York, researchers used NASA services that allowed flight operators to submit flight plans prior to departure, obtain risk assessment results, and then decide whether to proceed with flights or change their flight plans and re-assess risks. Allowing operators to perform these tasks quickly reduces the safety risk to flight passengers as well as humans on the ground.
The three NASA-developed services are intended to assess unique risks associated with highly automated aircraft flying at low altitudes over cities.
The partnership was managed under a Phase III NASA Small Business Innovation Research (SBIR) contract, which is an extension of prior work to assess weather-related risks. This collaboration is already leading to direct technology transfer of safety systems into ResilienX’s platform. The partnership is also intended to provide indirect benefits for ResilienX partners and customers, such as the U.S. Air Force and regional operators, helping to advance the overall safety of future airspace operations.
This work is led by NASA’s System-Wide Safety project under the Airspace Operations and Safety program in support of the agency’s Advanced Air Mobility mission. The mission seeks to deliver data, findings, and recommendations to guide the industry’s development of future air taxis and drones.
