Lead NASA hosted a news conference today to discuss analysis of the “Sapphire Canyon” rock sample from its Perseverance rover, revealing potential signs of ancient Martian microbes, as asteroid 2025 QV9 safely passed by Earth.

Nut Graf The unprecedented finding marks one of the strongest candidates yet for a Martian biosignature, underscoring NASA’s long-term search for life beyond Earth and emphasizing the importance of continuous monitoring of near-Earth objects.

Astrobiology Milestone

• The sample, collected in July 2024 from Neretva Vallis at Jezero Crater, exhibits minerals-vivianite and greigite-formed by electron-transfer reactions with organic matter, a potential microbial fingerprint.
• Katie Stack Morgan, Perseverance project scientist, cautioned that abiotic processes cannot be fully ruled out, highlighting the need for Earth-based laboratory analysis.

Perseverance’s Journey

• Since its 2021 landing, Perseverance has amassed 30 core samples, with six empty tubes remaining.
• Instruments aboard include a weather station for future human missions and spacesuit material test swatches.

Global Science Collaboration

• Acting NASA Administrator Sean Duffy and Nicky Fox, Science Mission Directorate associate administrator, joined Perseverance scientists to field media questions.
• The findings will be detailed in an upcoming peer-reviewed paper, reinforcing scientific rigor in assessing potential extraterrestrial life.

Celestial Watch: Asteroid 2025 QV9

• Asteroid 2025 QV9, approximately 100 feet wide and traveling at 10,319 mph, made a close approach of 1.25 million miles-five times the Earth-Moon distance-today, posing no threat.
• Classified outside NASA’s hazardous threshold, its flyby underscores ongoing vigilance in tracking near-Earth objects.
