I’ve been exploring Mars for more than 12 years – and it still surprises me with its beauty! For instance: These iridescent clouds drifting high in the Martian sky. Studying them provides insight into Mars' atmosphere – valuable info for future robotic and human missions.

Just published! Even NASA cleanrooms—designed to be ultra-clean—harbor resilient, novel bacteria. 26 new species were found, some forming biofilms, resisting radiation, and producing biotech-relevant compounds. Check it here: microbiomejournal.biomedcentral.com/articles/10.11…

Wishing upon a... moon? That bright "star" is actually Mars' moon Deimos. In the hours before dawn, I snapped this long-exposure image with my left Navcam and caught Deimos as well as two stars from the constellation Leo in the sky. It's definitely a mood, as they say.
