Mars Guy investigates a new finding from the NASA Curiosity Mars rover – tiny parallel lines. Curiosity uses an autonomous targeting system to look for interesting features for its laser-powered Chemistry and Camera (ChemCam) instrument to shoot at.  The rover recently targeted a spot that displays tiny parallel lines that don’t look natural.  “Spoiler alert: […]

The China Manned Space Engineering Office (CMSEO) has released an official announcement regarding this year’s planned activities. In 2026, the country’s human space program will further advance two major missions: space station application and development, and manned lunar exploration. “Aiming to achieve China’s first lunar landing before 2030,” the CMSEO stated, “the development and construction […]

  It was quite the day! How best to troubleshoot NASA’s Moonshot program? NASA Administrator Jared Isaacman revealed on February 27 a reconfigured plan for the Artemis program.
