Listeners, the past week has brought some significant updates and discoveries in the world of Mars exploration. ESA’s long-standing orbiters at Mars—Mars Express and ExoMars Trace Gas Orbiter—were recently redirected from their usual planetary observations to study the interstellar visitor 3I/ATLAS. Around October 3rd, these orbiters used their advanced imaging and spectrometer instruments to capture vital data on the comet’s activity as it passed just 30 million kilometers from Mars, an event that won’t be repeated for years. Scientists now anticipate these results will shed light on both the comet’s composition and the interactions between Martian orbiters and passing interplanetary objects, according to Sky at Night Magazine.

In mission progress, NASA’s Perseverance rover has now surpassed 1,640 Martian sols of activity since landing in Jezero Crater. The rover continues to drill, cache samples, and photograph terrain in its search for evidence of ancient microbial life. Notably, NASA’s recent update highlighted that, by July this year, Perseverance had filled 33 out of its 43 sample tubes with a diverse collection of rocks, regolith, and atmospheric samples. These are being prepped for the historic Mars Sample Return campaign, which could bring Martian material back to Earth for the first time in history. Scientists are excited about a specific sample from a dry riverbed in Jezero Crater, considered one of the most promising locations for discovering preserved signs of ancient life. NASA notes that this material may contain potential biosignatures, though further examination is required before any definitive claims are made.

Amidst these exciting discoveries, discussion around future missions gained new momentum at the Mars Society’s 28th Annual International Convention, hosted in Los Angeles from October 9 to 11. Leading figures from NASA, ESA, and pioneering tech companies debated next steps for Mars exploration. With renewed focus on sample retrieval, long-duration astronaut missions, and sustainable technology development, participants stressed international and commercial collaboration as the key to advancing human presence on Mars. Rob Manning of JPL and other experts underlined the enormous challenges—and opportunities—that lie ahead as the exploration calendar for Mars stretches into the next decade.

With orbiters capturing rare comet events, rovers drilling for signs of life, and engineers planning for human expeditions, Mars remains at the forefront of scientific innovation and discovery.
