Mars & Deep Space — 2026-09-27
Perseverance remains in top science form this week, revealing evidence of ancient hot-water systems in Jezero Crater while marking over five years and 28 miles of exploration. NASA also published fresh analysis of complex groundwater systems on early Mars. Deep space headlines were quiet this period, with Europa Clipper's Earth gravity assist looming in December.
Mars & Deep Space — 2026-09-27
Mars Missions Update
Perseverance Rover
- Current Status: After five years and 28 miles (over 45 km) of driving on Mars, Perseverance is still actively traversing the Martian landscape in search of clues to ancient, extinct life
- Latest Findings: New results from the Margin Unit region of Jezero Crater show evidence of ancient hot water — revealing how groundwater, surface water, and hydrothermally heated fluids shaped the area billions of years ago. "Mars constantly throws surprises at you," mission scientists note
Also this week, coverage revisited Perseverance's first AI-planned drives — conducted using generative AI to create waypoints through Jezero Crater's rim without human input, a task normally performed by human rover planners
Curiosity Rover
No fresh (post-2026-09-20) updates available for this section. The most recent confirmed milestone — 1 km of elevation gain up Mount Sharp — was reported in August and falls outside this issue's coverage window.
Other Mars Missions
- MRO / HiRISE: No fresh updates this cycle; recent HiRISE coverage of Perseverance's tracks dates from June and was covered in previous issues.
- No fresh data available this week for MAVEN, TGO, Tianwen-1, or Hope.
Deep Space Highlights
Europa Clipper
- Status: Cruising toward Jupiter on its Falcon Heavy-launched trajectory (launched Oct. 14, 2024; Jupiter orbit arrival planned for April 2030).
- What's New: The mission's next major milestone is its second Earth gravity assist on Dec. 3, 2026, which will give the spacecraft a push for the remainder of its trip to Europa
No other deep space missions (Artemis, JUICE, Psyche, New Horizons) had verified updates published after 2026-09-20.
Science Spotlight
NASA published new analysis this week on complex water systems on early Mars, drawing on Perseverance's exploration of the inner edge of Jezero Crater — a region scientists found surprisingly complex when first reached in 2023. The findings illuminate how groundwater and surface water interacted on ancient Mars
Upcoming Events
- Dec. 3, 2026 — Europa Clipper's second Earth gravity assist flyby, a key boost toward Jupiter arrival in 2030
- Perseverance science teams continue analyzing the Margin Unit hot-water findings; expect further released results in coming weeks
What to Watch Next
- Buildup to Europa Clipper's December Earth flyby — trajectory fine-tuning maneuvers may be announced in the coming weeks
- Follow-up publications on the ancient hot-water and complex groundwater systems evidence from Jezero Crater, which bear directly on Mars' past habitability
- Continued use of AI-planned driving on Perseverance, which could accelerate future traverse rates across the crater rim
