Near-Earth Rock Slips Through Detection Door Before Close Flyby

An asteroid the size of a blue whale will pass about 56,500 miles from Earth tonight (roughly 24% of the Earth–Moon distance), but it wasn’t discovered until roughly a week ago because key radar facilities are down after Arecibo’s collapse and ongoing Goldstone repairs; only about 1% of Earth-skimming asteroids this size get flagged, even as surveys like Vera Rubin Observatory discover thousands of new objects, highlighting gaps in our planetary defense.

Radar crosses unicorn threshold with $170M Series B for RFID-driven retail inventory

Radar, a RFID-based retail inventory startup backed by Jay Schottenstein, raised $170 million in a Series B led by Gideon Strategic Partners and Nimble Partners, valuing the company above $1 billion and expanding its deployments with retailers like American Eagle and Old Navy. The platform provides real-time in-store inventory visibility to reduce shrink and improve product availability, with reported gains in stock accuracy and lower order cancellation rates for buy-online-pickup-in-store.

Radar-Equipped Drones Aim to Locate Hidden Water on Mars

A new study demonstrates that drones carrying ground-penetrating radar can map shallow buried ice with high precision, using Earth glaciers in Alaska and Wyoming as analogs; the method could turn detection of Martian ice into actionable drill targets, bridging orbital surveys with surface exploration for future human missions.

NASA's NISAR Radar Tracks Century-Old Sinking in Mexico City

NASA’s new NISAR radar satellite has mapped ongoing subsidence in Mexico City, with some zones sinking more than 2 cm per month as the city sits on a drained lakebed. The readings from Oct 2025 to Jan 2026 demonstrate NISAR’s ability to measure ground deformation in dense, cloudy environments and are openly available, highlighting continued urban infrastructure risks and offering a global tool for monitoring subsidence.

Iranian missiles test NATO radar defenses in Turkey, focusing on Malatya

Iranian missiles heading toward Turkey were intercepted by NATO air defenses near Hatay and by US destroyers near Incirlik, with analysts suggesting the strikes were meant to test NATO’s air-defense network and potentially assess the Kurecik TPY-2 radar in Malatya; NATO deployed new Patriot batteries to Malatya, highlighting the EPAA and ‘engage on remote’ concept.

Hidden Lava Tubes Hint at a Subsurface Network Beneath Venus

Researchers analyzing radar data from the Magellan mission detected what appears to be a large underground lava tube beneath Venus, near the Nux Mons region. The tube is about 1 kilometer wide, with a roof around 150 meters thick and a hollow cavity at least 375 meters high, marking the first confirmed subsurface feature on Venus and supporting long-held ideas about the planet’s volcanic activity. If confirmed, there may be more tubes beneath Venus’ surface, a task for upcoming radar-focused missions VERITAS and EnVision, planned to launch around 2031.

Venus Unveils Its Largest Known Lava Tube

A Nature Communications study using NASA’s Magellan radar data finds a giant subsurface lava tube beneath Venus’ Nyx Mons, about 1 kilometer in diameter and potentially extending at least 45 kilometers, providing the strongest direct evidence yet of Venusian lava tubes; confirming the full extent will require higher-resolution radar data.

Biomass satellites frees its data stream to illuminate global forest carbon

ESA’s Biomass, a P-band radar satellite launched in 2025, has completed commissioning and now offers free, public access to its data to map forest structure and carbon storage. The mission begins with an 18-month global tomographic coverage, followed by multiple nine-month interferometric coverages to monitor forest change over time, with an airborne calibration campaign in Gabon aiding data validation and calibration. The effort aims to reduce uncertainties in global forest carbon stocks and support climate science and forest management.

Borderlands 4 Introduces Exciting New Feature Amid Minimap Changes

Gearbox has added a radar feature to Borderlands 4, responding to fan requests, which will help players with situational awareness. The radar, a departure from the mini-map, was developed quickly by the team and will be available at launch in September, with other fan-requested features also included. The game will launch on PC, PS5, and Xbox Series X|S, with a Switch 2 version coming later.

Cold War Ice Base Uncovered by NASA Radar

NASA scientists, using advanced radar technology, have rediscovered Camp Century, a Cold War-era U.S. military base buried beneath Greenland's ice. Originally constructed in 1959 for nuclear missile testing, the base was abandoned in 1967 and now lies under nearly 100 feet of ice. The discovery raises concerns about potential environmental hazards if melting ice exposes the base's remnants, including radioactive waste. The radar imagery, obtained by chance, highlights the importance of understanding ice sheet dynamics in the context of climate change.

"Michigan Counties on Alert: Severe Storms and Tornadoes Expected"

A severe thunderstorm watch is in effect for most of southern Lower Michigan until 7 p.m., with a fast-moving line of severe storms already formed and moving east across the region. The storms are expected to hit quickly and be over rapidly, with the most severe part lasting only a few minutes. The main threats include brief gusts of around 60 mph, large hail, and the possibility of isolated tornadoes. Residents are advised to seek shelter indoors and stay updated on the rapidly changing radar imagery.

"Severe Storms Threaten Ohio: Tornado Watch Issued for Multiple Regions"

A Tornado Watch is in effect for central, northern, and western Ohio until 7 p.m., with the potential for strong to severe storms later in the day. Morning rain is expected to give way to partly cloudy skies and temperatures in the upper 70s, with brisk winds aiding in temperature increase. Severe storms with damaging winds, large hail, and isolated tornadoes are possible, particularly in Northern Ohio. Showers and storms are likely early Friday, followed by a cool and dry weekend.

"Northeast Braces for Blustery Winter Storm with Strong Winds and Heavy Snow"

Wet snow and strong wind gusts will create hazardous driving conditions overnight and into Monday morning in Westvale, NY, with snow-covered, slippery roads and significant blowing snow. Winter weather and wind alerts are in effect, with conditions expected to improve by late afternoon. Snowfall accumulations will vary depending on elevation, and meteorologist Sam Postitch will provide live updates on NBC3 and CBS5 starting at 4 a.m.

"Using Radar to Detect Hazardous Asteroids"

Ground-based radar systems, such as NASA's Goldstone Solar System Radar and the National Radio Astronomy Observatory's (NRAO) next-generation RADAR (ngRADAR) system, could play a crucial role in detecting and tracking potentially threatening asteroids and comets. These systems have the potential to significantly impact asteroid detection and planetary defense efforts. With over 1.1 million known asteroids in the solar system, the ability to detect and track Near-Earth Objects (NEOs) is crucial for protecting Earth from potential impacts. Radar technology not only aids in asteroid detection but also provides detailed insights into the solar system's geology, making it a valuable tool for planetary scientists.
