Sols 4309–4310: Leaning Back, Driving Back
NASA’s Mars rover Curiosity captured this image of a large fractured slab of bedrock, taken by Right Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4307 — Martian day 4,307 of the Mars Science Laboratory Mission — on Sept. 17, 2024 at 15:50:36 UTC. Earth planning date: Wednesday, Sept. 18, 2024
The lengthy drive planned on Monday executed as expected, and we came in today to find our rover parked at a jaunty angle on a sloped ridge. There were some worries that the slope might limit our ability to use the arm for contact science in this plan (we don’t want to do anything that might cause the rover to slide down the slope!), but after some careful consideration, we received the good news that all six of our wheels are holding on firmly to the ground, so there was no risk of slipping.
On Monday, two different options for today’s plan were laid out. The first option, a “full contact science” plan where we don’t drive, was to be executed if Monday’s drive put us exactly where we hoped. The second, a “touch-and-go” plan where we do some light contact science before driving away, was to be executed if the drive didn’t put us where we wanted to be. As it happened, the rover was a little too enthusiastic about driving, and actually put our desired workspace under its body rather than in front where the arm could reach it. There’s always a little uncertainty in the final position after such a long drive! So, we decided to stick with a touch-and-go plan that includes a tiny backwards drive of less than a metre to reposition our desired target in front of the rover.
Although we need to re-position, we aren’t slowing down on science for even a second. We are parked in front of a large fractured slab of bedrock, which can be seen in the above image. This slab became the contact science target for this plan with DRT and APXS activities on “The Minster.” Mastcam is getting a workout today as well, with large mosaics of “North Channel,” “Buckeye Ridge,” “Quinn,” and “Island Pass.” These mosaics are all documenting various aspects of the ridge we’re sat on and the edge of the Gediz Vallis Channel, including sedimentary rocks, white sulphate materials, and gravels and fine-grained materials. ChemCam is also taking a turn on the bedrock slab with a LIBS activity on “Grand Sentinel” and a mosaic of some exposed white stones off in the distance.
The second sol of the plan, after our short drive, is largely taken over by environmental science activities, though there is our usual post-drive ChemCam AEGIS. These activities include a Mastcam tau and Navcam line-of-sight to measure the amount of dust in the atmosphere around and above us, as well as a dust devil movie, suprahorizon cloud movie, and some Navcam deck monitoring to see if our driving or the wind is moving around any of the sand and dust on the rover deck. The team is also taking the usual set of REMS, RAD, and DAN observations.

Back to Fire Science Landing Page FireSense
The FireSense project is focused on delivering NASA’s unique Earth science and technological capabilities to operational agencies, striving to address challenges in US wildland fire management. The project concentrates on four use-cases to support decisions before, during, and after wildland fires. These include the measurement of pre-fire fuels conditions, active fire dynamics, post fire impacts and threats, as well as air quality forecasting, each co-developed with identified wildland fire management agency stakeholders.
Strategic Tac Radio and Tac Overwatch (STRATO)
The Strategic Tac Radio and Tac Overwatch (STRATO) system is designed to provide real-time fire observations and last-mile communications with firefighters from stratospheric platforms. By providing persistent communications to a wildfire response team for a week or longer, STRATO is expected to offer capabilities beyond the currently used tethered balloons, which have a limited range and coverage area. By achieving station-keeping at altitudes up to 70,000 feet above ground level—to be demonstrated in flight testing—the STRATO will be able to provide communications to incident response teams in areas with no cellphone coverage.

FATE: dFAD Trajectory Tool
FATE will quantify dFAD (drifting fish aggregating devices) activity in relation to ocean currents, fish biomass, and animal telemetry at Palmyra Atoll, which is a U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge and is part of the U.S. Pacific Remote Islands Marine National Monument (PRIMNM) in the central Pacific Ocean. This innovative decision support tool will use NASA observations and numerical models to predict future dFAD trajectories and inform resource managers whether they should deploy tactical resources (boats, personnel) to monitor, intercept, or retrieve dFADs that have entered the MPA.
SeaSTAR
SeaSTAR aims to provide multi-spectral aerosol optical depth (AOD) and aerosol optical properties using a custom-built robotic sun/sky photometer. The instrument is designed to operate from a ship and is planned to deploy aboard the NOAA research vessel RV Shearwater in September 2024 to support the PACE-PAX airborne campaign.
PACE Validation Science Team Project: AirSHARP
Airborne asSessment of Hyperspectral Aerosol optical depth and water-leaving Reflectance Product Performance for PACE
The goal of AirSHARP is to provide high fidelity spatial coverage and spectral data for ocean color and aerosol products for validation of the PACE Ocean Color Instrument (OCI). Coastal influences on oceanic waters can produce high optical complexity for remote sensing especially in dynamic waters in both space and time. Dynamic coastal water features include riverine plumes (sediments and pollution), algal blooms, and kelp beds. Further, coastal California has a range of atmospheric conditions related to fires. We will accomplish validation of PACE products by combined airborne and field instrumentation for Monterey Bay, California.
Water2Coasts
Watersheds, Water Quality, and Coastal Communities in Puerto Rico
Water2Coasts is an interdisciplinary island landscape to coastal ocean assessment with socioeconomic implications. The goal of Water2Coasts is to conduct a multi-scale, interdisciplinary (i.e., hydrologic, remote sensing, and social) study on how coastal waters of east, and south Puerto Rico are affected by watersheds of varying size, land use, and climate regimes, and how these may in turn induce a variety of still poorly understood effects on coastal and marine ecosystems such as coral reefs and seagrass beds.
US Coral Reef Task Force (USCRTF)
The USCRTF was established in 1998 by Presidential Executive Order to lead U.S. efforts to preserve and protect coral reef ecosystems. The USCRTF includes leaders of Federal agencies, U.S. States, territories, commonwealths, and Freely Associated States. The USCRTF helps build partnerships, strategies, and support for on-the-ground action to conserve coral reefs. NASA ARC scientists are members of the Steering Committee, Watershed Working Group, and Disease and Disturbance Working Group, and lead the Climate Change Working Group to assist in the use of NASA remote sensing data and tools for coastal studies, including coral reef ecosystems. Data from new and planned hyperspectral missions will advance research in heavily impacted coastal ecosystems.
CyanoSCape
Cyanobacteria and surface phytoplankton biodiversity of the Cape freshwater systems
The diversity of phytoplankton is also found in freshwater systems. In Southern Africa, land use change and agricultural practices has hindered hydrological processes and compromised freshwater ecosystems. These impacts are compounded by increasingly variable rainfall and temperature fluctuations associated with climate change posing risks to water quality, food security, and aquatic biodiversity and sustainability. The goal of CyanoSCape is to utilize airborne hyperspectral data and field spectral and water sample data to distinguish phytoplankton biodiversity, including the potentially toxic cyanobacteria.
mCDR: Marine Carbon Dioxide Removal
The goals of this effort are to conduct literature review, analysis, and ocean simulation to provide scientifically vetted estimates of the impacts, risks, and benefits of various potential mCDR methods.
