The world’s most powerful supercomputer, El Capitan, has been officially launched at the Lawrence Livermore National Laboratory (LLNL) in California. Built at a cost of $600 million, the system has been designed to manage highly classified national security tasks. The primary objective of the supercomputer is to ensure the security and reliability of the U.S. nuclear stockpile in the absence of underground testing, which has been prohibited since 1992. Research in high-energy-density physics, material discovery, nuclear data analysis, and weapons design will be conducted, along with other classified operations.

Performance and Capabilities

According to reports, El Capitan became the fastest supercomputer globally after achieving 1.742 exaFLOPS in the High-Performance Linpack (HPL) benchmark. The system has a peak performance of 2.746 exaFLOPS, making it the third machine ever to reach exascale computing speeds. The measurement, taken in floating-point operations per second (FLOPS), represents the ability of the supercomputer to perform one quintillion (10^18) calculations per second.

As reported by space.com, the second-fastest supercomputer, Frontier, located at Oak Ridge National Laboratory in Illinois, has recorded a standard performance of 1.353 exaFLOPS, with a peak of 2.056 exaFLOPS. El Capitan’s significant advancement marks a leap in computational capabilities within high-performance computing.

Technical Specifications

As reported by The Next Platform, El Capitan is powered by over 11 million processing and graphics cores distributed across 44,544 AMD MI300A accelerated processing units. These units incorporate AMD EPYC Genoa CPUs, AMD CDNA3 GPUs, and shared computing memory. Each processing unit includes 128 gigabytes of high-bandwidth memory, designed to optimise computational efficiency while minimising power consumption.

Development and Commissioning

Reports indicate that construction of El Capitan began in May 2023, with the system going online in November 2024. The official dedication took place on January 9, 2025. The supercomputer was commissioned by the U.S. Department of Energy’s CORAL-2 program as a successor to the Sierra supercomputer, which was deployed in 2018 and currently ranks 14th in the latest Top500 list of most powerful supercomputers.

With El Capitan’s full-scale deployment, advancements in national security research and computational science are expected to reach unprecedented levels.

Raphael Domjan Soars to 8,224 Meters in SolarStratos

Raphael Domjan, Swiss Aviator, came close to reaching the distance of a world record while flying a solar Stratos plane on Sunday. He departed from Sion Airport in Southwestern Switzerland, reaching an altitude of 8224 meters; it lasted for four hours. Domjan, tagged as an eco-explorer for his aviation focus, and is known for his eco-friendly ambitions. According to him, achieving a height of more than 10,000 meters is still a dream for him to come true soon, hopefully.

Raphael Domjan Sets New SolarStratos Altitude Record

As per TechExplore, In 2010, Andre Borschberg set the record for the highest flight in a solar plane for 9,235 meters as a Swiss pilot flying the Solar Impulse. Domjan won’t just break the record of Borschberg but also intends to fly to the same altitude just like commercial jets. The challenge is as important as Solar Stratos has a boundary on the altitude that it can reach and while relying on solar power only.

The Road to 10,000 Meters: A Green Aviation Dream

Prior to this attempt, Domjan completed a practice flight on July 31, reaching an altitude of 6,589 meters, which was a record for the SolarStratos. Last Friday, he attempted a flight, but the thermals which usually aid in altitude gain were absent. He decided to turn back to conserve battery power for future attempts.

Earlier this week, conditions proved more favorable, leading to a new record altitude for the SolarStratos. As an innovation, the plane has solar panels on its 24.8-meter wings, which power its batteries. During the flight’s solar charging cycle, the plane’s batteries will automatically recharge to full. Domjan and his team are preparing for the next record attempt to make sure it will be a guaranteed success.

Asked about the 10,000 meter target, Domjan believes it is a target which will be achieved only by relentless attempts. For him, it is about the achievement, and an achievement only possible through determination and resilience on the aviations of the future as a green revolution.

Singapore Researchers Build Maple Seed Drone with Record 26-Minute Flight

A flying robot inspired by the anatomy of a maple seed, samaras, was developed by researchers of the Singapore University of Technology and Design (SUTD). This new monocopter, besides flying much longer than other drones of its size, proves its superiority by running on a single rotor for 26 minutes. This feat is a marked achievement, proving the goals of SUTD’s associate professor Foong Shaohui, who built a 50 minute flying drone for Singapore’s 50 year anniversary. Now, the focus shifts to efficiency in smaller designs.

Nature-Inspired Design Brings Breakthrough in Small Drone Efficiency

According to Techxplore, Nature proves to be the ultimate guide for the SUTD team, as they had previously designed quadcopters with no external help. In the case of maple seeds that spin and gently fall to the ground creating lift, the team built a singular powered wing monocopter. This improvement, while simple, also greatly enhances control, efficiency, effectiveness, and reduces weight.

The collective mix of human creativity with AI enabled tools to further enhance the designs fuel origami’s makes the monocopter a success. AI enabled tools allowed the team to simulate various shapes, angles, and weight before creating the final prototype. As a result, the team had a drone that is 32 grams while retaining the ability to endure more than other drones.

From 10-Year Challenge to Record-Breaking Maple Seed Monocopter

This small monocopter could be extremely beneficial for low-cost, long-duration missions. An example mission could be to transport instruments for measuring meteorological conditions. Taking home the Sustainability Winner award at the 2024 Dyson Awards felt like a decisive victory for monocopter, underscoring its potential for environmental monitoring missions. Now refinement efforts will target a larger payload, longer endurance, and extended range, all without adding weight.

The achievement shows the ten years of steady progress, which started from the SG50 quadcopter and evolved into the SG60 monocopter. It is planned for rollout during the 60th birthday of Singapore festivities. It has been guided by advanced engineering, insights from nature and on-board AI from the team has demonstrated the practical versatility and impressive performance of compact flying robots.

NASA’s Curiosity Rover Spots Ancient Coral-Like Rock on Mars

NASA’s Curiosity Mars rover used the Remote Micro Imager, part of its ChemCam instrument, to view a small, light-colored, wind-eroded rock, shaped like a piece of coral on July 24, 2025, the 4,609th Martian day, or sol, of the mission in Gale Crater. Curiosity has found many rocks like this one, which were formed by ancient water combined with billions of years of sandblasting by the wind. The approximately 1-inch-wide (2.5 centimeters) rock with its intricate branches. indicates that Mars once had a watery environment and could have supported life.

Geological Background

According to NASA, Curiosity has found many features like this that formed “billions of years ago when liquid water still existed on Mars” On early Mars, liquid water carried minerals into tiny fractures in rocks; when the water evaporated, it left behind mineral veins. Later, fast winds laden with sand eroded the surrounding rock, leaving behind intricate, branch-like concretions. This process – common on Earth in arid deserts – can create shapes that mimic biological forms, but are purely mineralogical. Thus, researchers stress the rock’s appearance is pseudofossil like: it looks like coral by chance, but is a geological artifact of past water activity. The find reinforces evidence of early Mars being wetter and possibilities of having microbial life.

Curiosity mission

Curiosity landed on Mars in 2012, touching down in the Gale Crater — a meteor impact crater on the boundary between the Red Planet’s cratered southern highlands and its smooth northern plains. The rover’s mission, led by NASA’s Jet Propulsion Laboratory in California, is to scan the Martian surface for any signs that it was habitable at any point in the distant past.The discovery was made on July 24, 2025 (Sol 4609 of the mission) by Curiosity’s ChemCam remote micro-imager and the image was released by NASA’s Jet Propulsion Laboratory in early August.
