  Artemis Era Raises Safety Concerns as Lunar Orbit Nears Capacity, New Study Finds

  As lunar exploration surges, scientists warn that the Moon’s limited stable orbits are growing crowded. Georgia Tech simulations suggest that with about 50 satellites, each may need several collision-avoidance maneuvers per year. Even now, orbiters like Chandrayaan-2 require frequent course corrections. With Artemis and private missions incoming,...

  NASA’s ESCAPADE Mission Will Send Twin Probes to Uncover Mars’s Atmospheric Secrets

  NASA’s ESCAPADE mission will launch twin mini-satellites, Blue and Gold, to Mars aboard Blue Origin’s New Glenn. The probes will study how solar wind stripped away Mars’s atmosphere and water, helping scientists understand the Red Planet’s lost climate and its transformation into the dry world we see today.

  Scientists Just Solved the Mystery of the Moon’s Lopsided Dust Halo

  Scientists have solved why the Moon’s dust cloud is uneven: heat. Using computer models, researchers found that meteor impacts on the Moon’s sunlit surface fling 6–8% more dust into space than on the cold night side, creating a lopsided halo. NASA warns this dust could threaten future landers and astronauts.

  Mystery Deepens as Interstellar Comet 3I/ATLAS Brightens Unexpectedly Near the Sun

  Interstellar comet 3I/ATLAS defied expectations during its 2025 solar flyby, brightening far faster than predicted. Observatories worldwide recorded a blue coma rich in exotic gases, suggesting unique chemistry from another star system. Scientists are investigating whether its unusual composition or speed caused the outburst, marking a new interste...

  NASA’s JWST Produces First-Ever 3D Map of Distant Planet WASP-18b

  NASA’s James Webb Space Telescope has created the first-ever 3D atmospheric map of an exoplanet, revealing the extreme conditions on WASP-18b, an “ultra-hot Jupiter” located 400 light-years away. Using infrared eclipse mapping, scientists discovered a scorching hotspot over 2,700 °C where water molecules are breaking apart. This groundbreaki...

  Earth’s Oxygen Explains Mysterious Rust Formation on the Moon

  Despite lacking air and water, the Moon hosts hematite—an oxidized iron mineral. Scientists discovered Earth’s escaping oxygen drives this rusting process during the Moon’s passage through the magnetotail. Observations from Chandrayaan-1 and NASA’s Lunar Reconnaissance Orbiter confirm hematite patches where Earth wind suppresses hydrogen an...

  NASA’s Perseverance Rover Finds Potential Signs of Life in Mars Rock Sample

  NASA’s Perseverance rover has uncovered iron-rich minerals in Jezero Crater rocks that on Earth often link to microbial activity. The discovery suggests Mars’ lake basin may have been more hospitable than thought. Still, scientists caution that only Earth-based analysis can confirm whether these are true biosignatures.
