Chang'e-6 samples shed light on lunar history, while SpaceX's Starship achieves another milestone with its 13th test flight.

The Chang'e-6 mission has returned samples from the Moon's far side, offering a glimpse into its ancient geological history. These samples, collected from the South Pole-Aitken Basin, are providing scientists with new data on the Moon's formation and evolution. The mission, led by the China National Space Administration (CNSA), marks a significant achievement in lunar exploration. For those interested in the mission's details, the Space Agencies directory provides more information on CNSA's objectives.

Starship's 13th Test Flight

SpaceX's Starship has successfully completed its 13th test flight, reaching space and marking another step towards operational readiness. The flight, which took place at the company's Texas launch site, tested several new systems and configurations. This milestone is part of SpaceX's broader plan to develop a fully reusable spacecraft capable of carrying humans to Mars and beyond. For those tracking the Starship's progress, the Launch Vehicles section provides a comprehensive overview.

Satellite Close Approaches

Several close approaches between satellites have been recorded, highlighting the growing congestion in low Earth orbit (LEO). Notably, the TIANHUI 2-01A and TIANHUI 2-01B satellites came within approximately 0.90 km of each other. These events underscore the importance of effective space traffic management to prevent potential collisions. The Debris Map offers a real-time view of space debris and active satellites, crucial for monitoring such close encounters.
