Robotic and planned human efforts to study and visit Mars, spanning rovers, orbiters, sample science, planetary protection rules, and mission support systems.
Curiosity has drilled its 48th Gale crater rock, a target called Basque Lakes, in the newly entered Cache Creek quad. A weekend X-ray diffraction run will give the first mineral data on how this rock formed and was later altered.
Reality
Curiosity's team planned four chemistry readings on blocks covered in disc-shaped lumps, a texture Earth rocks can show where evaporating fluid left minerals. Settling whether that happened on Mars will likely take the rover's next drill sample and its CheMin instrument.
Reality
NASA Administrator Jared Isaacman has returned NASA's Mars missions to COSPAR's 1964 limit of one-in-10,000 contamination odds per mission. The looser rule applies now, and a review due in December 2026 is meant to recommend lowering the threshold further.
Reality
Perseverance's SuperCam survey of more than 185 targets shows Jezero's Margin Unit is magma-formed olivine rock that met water at least three times. Groundwater and later hot fluids joined the crater lake in reworking it, so its carbonate is a harder record to read.
Reality
The mission's project scientist describes three hours to triage telemetry and agree on targets, then four more to compile commands that must fit the rover's available time and energy before sunrise on Mars.
Reality
NASA split $650,000 among five Mars to Table winners, led by a $300,000 design meant to produce half the food for 15 astronauts over 513 days on Mars. The entries are design concepts judged partly on how little crew time they need, so that 50% is a target until someone builds and measures it.
Reality
Orbiters read the carbonate at Jezero's margin as lake chemistry; Perseverance found volcanic rock that water altered at least three times, in a sequence the team can order but cannot date.
Reality
A Circulation study co-led by UT Southwestern measured astronaut hearts during six-month station missions, the window earlier work left blank, and reports the early shrinkage stayed inside what Mars-level gravity would demand.
Reality
A Circulation study followed cardiac structure through full six-month missions using ultrasound the crews ran themselves. Because every astronaut completed the prescribed exercise, it cannot separate the countermeasure from the adaptation.
Reality
The recommended limit is a quarter of the lunar standard, and it exists chiefly so engineers can size filters, airlocks and suit-cleaning hardware years before a crew flies.
Reality
A fabric Vivaldi antenna sheathed in Vectran has cleared testing at JPL, letting SkyFall drag a 500-2,500 MHz radar about 15 cm above the regolith and still survive dozens of landings.
