Sols 4366–4367: One of Those Days on Mars (Sulfate-Bearing Unit to the West of Upper Gediz Vallis)

A grayscale landscape photo from Mars, showing a broad, medium gray, rock-strewn plain in the foreground extending far into the distance, surrounded by several hills. The closest hill, in the lower right corner, rises up toward the side of the frame, and is darker than the floor below. A little farther out, on the left, a gentle slope rises from the low middle of the frame to middle of the left side; it’s about the same color as the valley floor, except for a band at its farthest edge, which darkens abruptly as if covered in shadow. The terrain appears softer than the ground below, more sandy than rocky. Beyond that along the same rising plane is a much lighter area, with scattered tiny peaks that are darker – looking like the top of a baked meringue pie. The channel floor runs between these hills, then appears to curve toward the right, behind the first hill and in front of the second. Finally, one other rounded peak appears above the horizon, behind these other two hills in the lower right of the frame, all of this below a light-gray sky filling more than half of the frame above.
NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on Nov. 14, 2024 — sol 4363, or Martian day 4,363 of the Mars Science Laboratory mission – at 02:55:34 UTC.

Earth planning date: Friday, Nov. 15, 2024

The Monday plan and drive had executed successfully, so the team had high hopes for APXS and MAHLI data on several enticing targets in the rover’s workspace. Alas, it was not to be: The challenging terrain had resulted in an awkwardly perched wheel at the end of the drive, so we couldn’t risk deploying the arm from this position. Maybe next drive!

We did plan a busy weekend of non-arm science activities regardless. Due to a “soliday” the weekend has two sols instead of three, but we had enough power available to fit in more than three hours of observations. The two LIBS observations in the plan will measure the composition of the flat, reddish material in the workspace that is fractured in a polygonal pattern (“Bloody Canyon”) and a nearby rock coating in which the composition is suspected to change with depth (“Burnt Camp Creek”). One idea is that the reddish material could be the early stage version of the thicker dark coatings we’ve been seeing.

A large Mastcam mosaic (“Yosemite”) was planned to capture the very interesting view to the rover’s north. Nearby and below the rover is the layer of rocks in which the “Mineral King” site was drilled on the opposite side of the channel back in March. This is a stratum of sulfate-bearing rock that appears dark-toned from orbit and we’re interested to know how consistent its features are from one side of the channel to the other. Higher up, the Yosemite mosaic also captures some deformation features that may reveal past water activity, and some terrain associated with the Gediz Vallis ridge. So there’s a lot of science packed into one mosaic!

Two long-distance RMI mosaics were planned; one is to image back into the channel, where there may be evidence of a late-stage debris flow at the base of the ridge. The second looks “forward” from the rover’s perspective instead, into the wind-shaped yardang unit above us that will hopefully be explored close-up in the rover’s future. This yardang mosaic is intended to form one part of a stereo observation.

The modern environment on Mars will also be observed with dust devil surveys on both sols, line-of-sight and tau observations to measure atmospheric opacity (often increased by dust in the atmosphere), and zenith and suprahorizon movies with Navcam to look for clouds. There will also be standard passive observations of the rover’s environment by REMS and DAN.

We’ll continue driving westward and upward, rounding the Texoli butte to keep climbing through the sulfate-bearing unit. It’s not always easy driving but there’s a lot more science to do!

      Sols 4458-4460: Winter Schminter
      NASA’s Mars rover Curiosity captured this image of the Texoli butte, a Martian landmark about 525 feet (160 meters) tall, with many layers that scientists are studying to learn more about the formation of this region of the Red Planet. The butte is on the 3-mile-high Mount Sharp, inside Gale Crater, where Curiosity landed and has been exploring since 2012. The rover acquired this image using its Left Navigation Camera on sol 4456, or Martian day 4,456 of the Mars Science Laboratory mission, on Feb. 17, 2025, at 17:51:56 UTC. NASA/JPL-Caltech Earth planning date: Tuesday, Feb. 18, 2025
      During today’s unusual-for-MSL Tuesday planning day (because of the U.S. holiday on Monday), we planned activities under new winter heating constraints. Operating Curiosity on Mars requires attention to a number of factors — power, data volume, terrain roughness, temperature — that affect rover operability and safety. Winter means more heating to warm up the gears and mechanisms within the rover and the instruments, but energy that goes to heating means less energy for science observations. Nevertheless, we (and Curiosity) were up to the task of balancing heating and science, and planned enough observations to warm the science team’s hearts. 
      We fit in DRT, APXS, and MAHLI on two different bedrock targets, “Chumash Trail” and “Wheeler Gorge,” which have different fracturing and layering features. In the workspace, ChemCam targeted a clean vertical exposure of layered bedrock at “Sierra Madre” and a lumpy-looking patch of resistant nodules at “Chiquito Basin.” 
      The topography of the local terrain and our end-of-drive position after the weekend fortuitously lined up to give us a view of an exposure of the Marker Band, which we first explored on the other side of Gediz Vallis Ridge. Having a view of another exposure of this distinctive horizon helps give us further insight into its origin, so we included both RMI and Mastcam mosaics of the exposure. 
      Documenting a feature that, unlike the Marker Band, has been and will be in our sights for a long time — “Texoli” butte (pictured above) — was the goal of additional Mastcam and ChemCam imaging. Observations of potential sedimentary structures on the flank of Texoli motivated acquisition of an RMI mosaic, and a chance to capture structures along its southeast face inspired a Mastcam mosaic. Good exposures of additional nearby bedrock structures at “Mount Lukens” and “Chantry Flat” drew the eye of Mastcam, while another small mosaic focused on the kind of linear troughs in the sand we often see bordering bedrock slabs. Environmental observations included Navcam cloud and dust-devil movies, Mastcam observations of dust in the atmosphere, and REMS and RAD measurements spread across the three sols of the plan.

      The Crew Health and Performance Exploration Analog (CHAPEA) team hosts a Media Day at NASA’s Johnson Space Center in Houston on April 11, 2023.Credit: NASA Media are invited to visit NASA’s simulated Mars habitat on Monday, March 10, at the agency’s Johnson Space Center in Houston. The simulation will help prepare humanity for future missions to the Red Planet.
      This is the second of three missions as part of NASA’s CHAPEA (Crew Health and Performance Exploration Analog), set to begin in May 2025 when volunteer crew members enter the 3D printed habitat to live and work for a year.
      During the mission, crew members will carry out different types of mission activities, including simulated “marswalks,” robotic operations, habitat maintenance, personal hygiene, exercise, and crop growth. Crew also will face planned environmental stressors such as resource limitations, isolation, and equipment failure.
      The in-person media event includes an opportunity to speak with subject matter experts and capture b-roll and photos inside the habitat. Crew members will arrive for training at a later date and will not be available at this event.
      To attend the event, U.S. media must request accreditation by 5 p.m. CDT Monday, March 3, and international media by 5 p.m., Monday, Feb. 24, via the NASA Johnson newsroom at: 281-483-5111 or jsccommu@nasa.gov. Media accreditation will be limited due to limited space inside the habitat. Confirmed media will receive additional details on how to participate.

      How Long Does it Take to Get to the Moon... Mars... Jupiter? We Asked a NASA Expert

      Preparations for Next Moonwalk Simulations Underway (and Underwater)

      During the Apollo program, when NASA sent humans to the Moon, those missions took several days to reach the Moon. The fastest of these was Apollo 8, which took just under three days to go from Earth orbit to orbit around the Moon.

      Now it’s possible to save some fuel by flying different kinds of trajectories to the Moon that are shaped in such a way to save fuel. And those trajectories can take more time, potentially weeks or months, to reach the Moon, depending on how you do it.

      Mars is further away, about 50 percent further away from the Sun than Earth is. And reaching Mars generally takes somewhere between seven to ten months, flying a relatively direct route.

      NASA’s Mars Reconnaissance Orbiter mission took about seven and a half months to reach Mars. And NASA’s MAVEN mission took about ten months to reach Mars.

      Jupiter is about five times further away from the Sun than the Earth is. And so in order to make those missions practical, we have to find ways to reduce the fuel requirements. And the way we do that is by having the spacecraft do some flybys of Earth and or Venus to help shape the spacecraft’s trajectory and change the spacecraft’s speed without using fuel. And using that sort of approach, it takes between about five to six years to reach Jupiter.

      So NASA’s Galileo mission, the first mission to Jupiter, took just a little over six years. And then NASA’s second mission to Jupiter, which was called Juno, took just under five years.

      So to get to the Moon takes several days. To get to Mars takes seven to ten months. And getting to Jupiter takes between five and six years.
