• NASA released a timelapse video showing the Psyche spacecraft's perspective as it zoomed past Mars in May 2026. • While the mission did not expect major new discoveries due to Mars' extensive history of study, the spacecraft provided a unique vantage point for data collection. • This flyby serves as a complementary addition to existing Mars science, utilizing Psyche's specific trajectory and instrumentation.

• Fifty years after the NASA Viking 1 lander touched down on Mars, scientists continue to debate whether the mission discovered evidence of extraterrestrial life. • A recent analysis suggests that Viking 1 likely found autotrophic microbial life, estimating a density of approximately 1,000 cells per gram of soil. • The debate persists because the original results were ambiguous, leaving the scientific community divided on whether the findings were biological or chemical in nature.

• NASA's Psyche spacecraft successfully completed a flyby of Mars, capturing a significant trove of data and a time-lapse video of the encounter. • Mission scientists used the flyby to calibrate instruments under dynamic conditions and study the physics of planetary magnetism. • This calibration phase is a critical step in ensuring the spacecraft's systems are fully operational before it reaches its primary target.

• NASA's Curiosity rover has discovered an unusual honeycomb-like texture on the Martian surface. • The findings include these strange geometric patterns alongside various dark rocks scattered across the area. • This discovery is significant as it presents a new geological mystery for researchers to investigate regarding Mars' surface composition.
