Mars exploration reached new highs as NASA captured images of interstellar comet 3I/ATLAS near Mars, prepared for the upcoming ESCAPADE mission, and advanced human landing simulations. Read the latest breakthroughs and next steps for sending humans to Mars.
Interstellar Comet 3I/ATLAS Captured Near Mars
An extraordinary event unfolded this week as the interstellar comet 3I/ATLAS, only the third of its kind ever observed, made its closest approach to Mars on October 3. NASA’s Perseverance rover may have captured this rare visitor from the Martian surface on October 4, igniting excitement as experts pore over Navcam images to confirm the sighting. Meanwhile, ESA’s ExoMars and Mars Express orbiters attempted to photograph and analyze the comet’s coma and tail, providing scientists with unmatched data on this ancient traveler, suspected to be billions of years older than our Solar System. Ongoing analysis of rover and orbiter data aims to reveal the comet’s composition and origins, marking this as a milestone for both Mars and interstellar studies. NBC News | ESA | SSBCrack
Twin Mars Probes Set for Launch
On the mission planning front, NASA’s much-anticipated ESCAPADE probes, designed to study Mars’ magnetosphere, are set to launch aboard Blue Origin’s New Glenn rocket in mid-October. After a year’s delay to ensure mission safety, integration of these probes is now underway in Florida, with final rocket tests scheduled for the coming weeks. The twin satellites, built by Rocket Lab and operated by the University of California’s Space Sciences Laboratory, will deliver crucial data on Mars’ plasma environment, directly supporting long-term exploration and preparations for human arrival.

Simulating Mars Living: NASA’s CHAPEA Mission Begins Second Year-Long Analog
As interest in landing humans on Mars grows, NASA is taking essential steps to prepare astronauts for life on the Red Planet. The second year-long CHAPEA (Crew Health and Performance Exploration Analog) mission began this month at Johnson Space Center. Four specially selected crew members entered a 3D-printed habitat to simulate Martian living, testing their ability to handle real-life challenges like isolation, equipment failures, and resource constraints. Advanced technologies, from water systems to diagnostic medical tools, are being trialed. This data will inform future moon and Mars missions, refining strategies for crew health and performance during extended space travel. NASA
Global Collaboration: Planetary Protection and Human Mars Landing Preparations
Mars exploration isn’t only about science and technology—international planetary protection policies are being shaped now. This week, a new international working group was announced to set standards on planetary protection for Mars missions, with implications for both robotic and human explorers. These discussions are crucial for safeguarding Martian environments and future sample returns, a core step before landing humans on Mars. Astrobiology.com
