Asteroid 2025 PM2, about 190 feet in diameter, will pass Earth at a distance of 2.31 million miles on August 27, 2025. While not a threat, this close encounter allows scientists to study near-Earth objects and refine planetary defense strategies. Continuous monitoring is crucial for understanding orbital dynamics and potential hazards, as highlighted by ISRO's plans to study larger asteroids.

Elon Musk's SpaceX Starship, designed with 42 engines, cleverly blends engineering with a nod to Douglas Adams' "Hitchhiker's Guide." This choice symbolizes a fusion of ambition, humor, and philosophical depth, driving humanity towards interplanetary travel. The engine count reflects both the immense power needed for deep-space missions and a playful acknowledgment of life's ultimate questions.

NASA's telescopes have captured detailed observations of interstellar object 3I/ATLAS, confirming it as a natural comet rich in CO₂ and water ice. Discovered in 2025, the comet's composition and trajectory align with known processes of icy comets ejected from other star systems, debunking speculation about alien origins. Ongoing observations aim to understand its structure and activity.

NASA is preparing to launch three sounding rockets from Wallops Island, Virginia, on August 26, 2025, as part of the TOMEX+ mission. Residents across the mid-Atlantic may witness colourful vapour trails. The mission will study the mesopause, a critical atmospheric layer influencing weather and satellite operations.

SpaceX postponed its 10th Starship launch for the second day due to adverse weather at Starbase, Texas. The fully fueled Super Heavy booster and Starship upper stage faced cloudy conditions, delaying the test flight. SpaceX now targets Tuesday, August 26, for the launch, aiming to gather crucial data for Starship's reusable design and reentry capabilities.

The US Department of Health and Human Services has confirmed the first travel-associated human case of New World screwworm. The patient had returned from El Salvador and has since recovered. While the risk to the public remains low, the parasite poses a significant threat to livestock, prompting increased prevention efforts and concerns among cattle ranchers, especially in Texas.

Indian researchers have engineered a novel filter using industrial waste to combat water pollution. The biochar-infused membrane, crafted from spice residue and tannery sludge, effectively removes dyes and antibiotics from wastewater. Developed by Shiv Nadar University, this cost-effective solution offers up to 83% pollutant removal and can be reused multiple times.

Humans lack the digestive enzymes and specialized anatomy to break down cellulose, the main component of grass, unlike herbivores. Early human ancestors consumed plant material, but their digestive systems weren't adapted for large quantities of cellulose-rich grasses. Grass offers minimal nutritional value, making it an unsuitable food source for humans, who require a varied diet.

SpaceX's Starship launch faced a delay. Engineers detected a ground system issue. A liquid oxygen leak caused the problem. Elon Musk confirmed the setback on X. The team is working to fix the leak. Another launch attempt is scheduled for Monday. Starship is vital for future Mars missions. Earlier, Falcon 9 also faced similar oxygen leak issues.

European Space Agency released stunning images of volcanoes taken from space. These images include Mount Vesuvius in Italy and Krakatoa in Indonesia. The release coincided with the anniversary of Vesuvius's deadly eruption in 79 AD. Astronauts on the International Space Station regularly photograph Earth. This helps scientists track volcanic activity. The images showcase Earth's beauty and power.

NASA's James Webb Space Telescope has detected a new moon, S/2025 U1, orbiting Uranus. This tiny moon, only 10 kilometers in diameter, was missed by Voyager 2 nearly four decades ago. The discovery, made using Webb's Near-Infrared Camera, increases Uranus' known moons to 29, providing insights into the planet's complex moon and ring system and its dynamic history.

NASA's James Webb Space Telescope has potentially identified 300 ancient objects, possibly early galaxies formed shortly after the Big Bang. These unusually bright and developed structures challenge existing models of galaxy formation, suggesting a faster development timeline in the early universe. Confirmation through further spectroscopic analysis is crucial to solidify this groundbreaking discovery.

Elon Musk's Neuralink has successfully implanted a wireless brain chip in a paralyzed patient, Noland Arbaugh, enabling him to control digital devices with his thoughts. Arbaugh, paralyzed since 2016, can now play video games and manage daily tasks, regaining independence. While this breakthrough offers potential benefits like restoring autonomy and enhancing cognitive functions, it also raises ethical and safety concerns.

SpaceX's tenth Starship test flight faced an abrupt halt in Texas minutes before launch, intensifying suspense among space enthusiasts. This setback, following earlier failures this year, underscores the challenges in developing the massive rocket crucial for both NASA's lunar ambitions and Elon Musk's Mars vision. The flight aimed to test booster landings, heat shield durability, and satellite deployment.

SpaceX postponed Sunday's Starship test flight due to a ground systems issue, marking another setback for the giant rocket. The uncrewed test aimed to push the upper stage through trials, but past flights have faced explosions. Despite reliability concerns and pressure from analysts, SpaceX maintains its rapid testing approach, with Musk still aiming for Mars missions next year.
