Sols 4327-4328: On the Road Again
This image was taken by NASA’s Mars rover Curiosity using its Left Navigation Camera on sol 4326 — Martian day 4,326 of the Mars Science Laboratory mission — on Oct. 7, 2024, at 01:16:16 UTC. NASA/JPL-Caltech Earth planning date: Monday, Oct. 7, 2024
After successfully completing investigations within Gediz Vallis, Curiosity is back on the road through the Mg-sulfate (magnesium sulfate) bearing unit. The terrain under our wheels is a familiar collection of broken up blocks, and we’re keeping our rover eyes on the more distant stratigraphy and the deposits within the Gediz Vallis channel (as seen in the above Navcam image). Our traverse along this side of the channel is a great chance to understand the erosional and depositional history of Gediz Vallis from a different perspective, and to characterize variations in the sulfate unit.
I was on shift as Long-Term Planner today, and it was a pretty straightforward two-sol plan, with contact science on the first sol and driving on the second sol. The team planned a great collection of measurements to characterize the rocks in our workspace and more distant features.
The plan starts with remote sensing, including ChemCam LIBS on a gray, smooth slab at “Paloma Meadows,” followed by two long-distance RMI mosaics to assess the thickness and distribution of white clasts in Gediz Vallis. Then Mastcam will document Paloma Meadows and a distant dark clast at “Sky Parlor Meadow” to understand the variety of rock types and where they might have come from. The remote sensing block also includes a Navcam observation to search for dust devils. Later in the afternoon Mastcam will acquire a mosaic looking back towards “Whitebark Pass” including the white clasts (some of which were previously tied to observations of high sulfur) and the distribution of deposits within “Pinnacle Ridge.” Then Curiosity will use the instruments on the arm to assess one of the blocks in our workspace at “Pincushion Peak.” We’ll use the DRT, MAHLI, and APXS to assess the grain size, textures, and composition of a nodular block of bedrock. On the second sol Curiosity will acquire ChemCam LIBS and Mastcam of Pincushion Peak, which will make for a nice set of coordinated observations. The second sol also includes a long-distance RMI mosaic of an interesting dark block to assess sedimentary structures, and two Navcam observations to characterize atmospheric opacity and the movement of fines on the rover deck. Then Curiosity will continue driving, and take post-drive imaging to prepare for a similar plan on Wednesday. Looking forward to continuing to explore what’s under our wheels and on the horizon!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA astronaut Yvonne Cagle and former astronaut Kenneth Cockrell pose with Eli Toribio and Rhydian Daniels at the University of California, San Francisco Bakar Cancer Hospital. Patients gathered to meet the astronauts and learn more about human spaceflight and NASA’s cancer research efforts.NASA/Brandon Torres Navarrete NASA astronauts, scientists, and researchers, and leadership from the University of California, San Francisco (UCSF) met with cancer patients and gathered in a discussion about potential research opportunities and collaborations as part of President Biden and First Lady Jill Biden’s Cancer Moonshot initiative on Oct. 4.
Roundtable discussions centered conversation around the five hazards of human spaceflight: space radiation, isolation and confinement, distance from Earth, gravity, and closed or hostile environments. Many of these hazards have direct correlations to a cancer patient’s lived experience, like the isolation of a hospital room and long-term effects of radiation.
During the visit with patients at the UCSF Benioff Children’s Hospital San Francisco, NASA astronaut Yvonne Cagle and former astronaut Kenneth Cockrell answered questions about spaceflight and life in space.
Patients also received a video message from NASA astronauts Suni Williams and Butch Wilmore from the International Space Station, and met with Vanessa Wyche, director of NASA’s Johnson Space Center in Houston, Eugene Tu, director of NASA’s Ames Research Center in California’s Silicon Valley, and other agency leaders.
Leadership from NASA and the University of California, San Francisco gathered for an informal luncheon before a collaborative roundtable discussion of research opportunities. From left to right, Alan Ashworth, president of the UCSF Helen Diller Family Comprehensive Cancer Center, Eugene Tu, director of NASA’s Ames Research Center in California’s Silicon Valley, David Korsmeyer, deputy director of Ames, Sam Hawgood, chancellor of UCSF, and Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. By connecting the dots between human space research and cancer research, NASA and the University of California hope to open doors to innovative new research opportunities. NASA is working with researchers, institutions, and agencies across the federal government to help cut the nation’s cancer death rate by at least 50% in the next 25 years, a goal of the Cancer Moonshot Initiative.

On flight day 13, Orion reached its maximum distance from Earth during the Artemis I mission when it was 268,563 miles away from our home planet. Orion has now traveled farther than any other spacecraft built for humans.Credit: NASA NASA’s Orion spacecraft is designed to keep astronauts safe in deep space, protecting them from the unforgiving environment far from Earth. During the uncrewed Artemis I mission, researchers from NASA, along with several collaborators, flew payloads onboard Orion to measure potential radiation exposure to astronauts.
Radiation measurements were taken inside Orion by 5,600 passive sensors and 34 active radiation detectors during its 25.5-day mission around the Moon and back, which provided important data on exposure within the Earth’s Van Allen radiation belt. These detailed findings were published in a recent scientific article through a collaborative effort by NASA’s Space Radiation Analysis Group, the DLR (German Space Center), and ESA (European Space Agency). The measurements show that while radiation exposure can vary depending on location within Orion, the spacecraft can protect its crew from potentially hazardous radiation levels during lunar missions.
Space radiation could pose major risks to long-duration human space flights, and the findings from the Artemis I mission represent a crucial step toward future human exploration beyond low Earth orbit, to the Moon, and eventually to Mars.
NASA’s HERA (Hybrid Electronic Radiation Assessor) and Crew Active Dosimeter, which were tested previously on the International Space Station, and ESA’s Active Dosimeter, were among the instruments used to measure radiation inside Orion. HERA’s radiation sensor can warn crew members need to take shelter in the case of a radiation event, such as a solar flare. The Crew Active Dosimeter can collect real-time radiation dose data for astronauts and transmit it back to Earth for monitoring. Radiation measurements were conducted in various areas of the spacecraft, each offering different levels of shielding.

These manikins enabled measurements of radiation doses on various body parts, providing valuable insight into how radiation may affect astronauts traveling to deep space.
Two manikins are installed in the passenger seats inside the Artemis I Orion crew module atop the Space Launch System rocket in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Aug. 8, 2022. As part of the Matroshka AstroRad Radiation Experiment (MARE) investigation, the two female manikins – Helga and Zohar – are equipped with radiation detectors, while Zohar also wears a radiation protection vest, to determine the radiation risk on its way to the Moon.

Researchers found that Orion’s design can protect its crew from potentially hazardous radiation levels during lunar missions. Though the spacecraft’s radiation shielding is effective, the range of exposure can greatly vary based on spacecraft orientation in specific environments. When Orion altered its orientation during an engine burn of the Interim Cryogenic Propulsion Stage, radiation levels dropped nearly in half due to the highly directional nature of the radiation in the Van Allen belt.
“These radiation measurements show that we have an effective strategy for managing radiation risks in the Orion spacecraft. However, key challenges remain, especially for long-duration spaceflights and the protection of astronauts on spacewalks,” said Stuart George, NASA’s lead author on the paper.
NASA’s long-term efforts and research in mitigating space radiation risks are ongoing, as radiation measurements on future missions will depend heavily on spacecraft shielding, trajectory, and solar activity. The same radiation measurement hardware flown on Artemis I will support the first crewed Artemis mission around the Moon, Artemis II, to better understand the radiation exposure seen inside Orion and ensure astronaut safety to the Moon and beyond.
