Earth planning date: Monday, Oct. 21, 2024
After Curiosity’s busy weekend, the team is ready for another day of planning. We are able to take advantage of the Earth-Mars time offset to full plan on both sols of our plan today. For this plan, I served as Mobility Rover Planner, and planned Curiosity’s drive.
The first sol begins with some remote science. In this block, there is a ChemCam LIBS and Mastcam joint observation of “Ewe Lake,” to look for variation across the different layers in the rock. There is also a ChemCam RMI and a Mastcam of the “Olmstead Point” target, to see if there are chemical differences that make it darker than the surrounding rocks. Mastcam also is taking a stereo image of “Depressed Lake” (in order to see if this loose block belongs to the Stimson or the Sulfate units) and an image of the ChemCam AEGIS target the rover automatically found after the last drive.
After a nap, Curiosity wakes up to do some contact science on the “Chuck Pass” target, which is a piece of bedrock with laminations and nodules. We perform DRT brushing, MAHLI, and APXS observations of this rock before stowing the arm so we can be ready to drive on the second sol. In the late afternoon, to take advantage of the lighting conditions, we have another short set of Mastcam imaging — an atmospheric sky column observation and a stereo mosaic of “Fascination Turret” from this new angle.
The second sol also kicks off with some remote sensing. We follow up the contact science with ChemCam LIBS and Mastcam of Chuck Pass. ChemCam also takes an RMI looking east back to the area of the white sulfur stones below “Whitebark Pass” to get yet another viewing angle. There is also some atmospheric imaging, Navcam deck monitoring (to see how the dust is moving around on the rover’s deck) and a large dust devil survey.
After the imaging, we are ready to drive. This terrain has been very tricky. While the slopes are not steep, this is a very rocky area, as you can see in the image, making finding a safe path difficult. We don’t only need to worry about driving over things that are too big or too sharp, but we also have to make sure not to scrape the wheels along the side of a rock or steer them into a rock, making them wedge and stall. It also means that we do not have good stereo data out very far because the rocks block our view. The last complication is that we have to drive backwards — otherwise, the rover hardware will block Curiosity’s view of Earth during the time we want to send her the new plan. When we drive backwards, the rover hardware will block Curiosity’s view, so we need to turn to get a clear view in our images. We also take additional frames to be sure we can find the best path for the next drive. With all this, we ended up being able to drive about 32 meters today (about 105 feet). After a short diversion to get around a steering hazard, we were able to drive a fairly straight route along the path to our next major imaging stop. After the drive, we have our normal post-drive imaging, including a twilight MARDI image.
We have been lucky so far on this terrain and been able to successfully complete our recent drives. Hopefully this drive will also be successful!

NASA has selected the University of New Hampshire in Durham to build Solar Wind Plasma Sensors for the Lagrange 1 Series project, part of the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Next Program.
This cost-plus-no-fee contract is valued at approximately $24.3 million and includes the development of two sensors that will study the Sun’s constant outflow of solar wind. The data collected will support the nation’s efforts to better understand space weather around Earth and to provide warnings about impacts such as radio and GPS interruptions from solar storms.
The overall period of performance for this contract will be from Thursday, Oct. 24, and continue for a total of approximately nine years, concluding 15 months after the launch of the second instrument. The work will take place at the university’s facility in Durham, New Hampshire, and at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. Johns Hopkins is the significant subcontractor.
Under this contract, the University of New Hampshire will be required to design, analyze, develop, fabricate, integrate, test, verify, and evaluate the sensors, support their launch, supply and maintain the instrument ground support equipment, and support post-launch mission operations at the NOAA Satellite Operations Facility in Suitland, Maryland.
The Solar Wind Plasma Sensors will measure solar wind, a supersonic flow of hot plasma from the Sun, and provide data to NOAA’s Space Weather Prediction Center, which issues forecasts, warnings and alerts that help mitigate space weather impacts. The measurements will be used to characterize coronal mass ejections, corotating interaction regions, interplanetary shocks and high-speed flows associated with coronal holes. The measurements will also include observing the bulk ion velocity, ion temperature and density and derived dynamic pressure.
NASA and NOAA oversee the development, launch, testing, and operation of all the satellites in the L1 Series project. NOAA is the program owner that provides funds and manages the program, operations, and data products and dissemination to users. NASA and commercial partners develop, build, and launch the instruments and spacecraft on behalf of NOAA.

Clouds curling around the full “blue” moon gives the night sky an eerie feel in this image from Aug. 19, 2024. As seen here, a blue moon is not actually blue; the third full moon in a season with four full Moons is called a “blue” moon.
Another moon will be visible in the sky the morning of Oct. 25: Jupiter’s icy moon Europa, the destination of NASA’s recently launched Europa Clipper, will be easily observable with binoculars on one side of Jupiter by itself.

Listen to Chief AI Officer Dave Salvagnini represent NASA in a Federal Executive Forum webinar on “Artificial Intelligence Strategies in Government Progress and Best Practices 2024.”
Dave Salvagnini
NASA Chief Artificial Intelligence Officer, and Chief Data Officer
Featuring Chief AI Officers and technology experts at the IRS, Office of the National Coordinator for Health Information Technology, Red Hat, Deloitte, and Pure Storage, this discussion covers current AI use cases across the private and public sectors. Artificial intelligence, particularly GenAI, is changing landscapes ranging from medicine to tax systems to aeronautics. The webinar covers AI use cases for medical devices, tax amendments, and more, including a segment on how NASA is using AI capabilities for earth sciences, climate modeling, and deep space exploration. Although NASA has a long history with AI, Salvagnini notes, GenAI is changing the way we view and use these technologies. How do we equip the workforce to democratized, accessible AI capabilities, and what policies should we create to mitigate potential risks like bias, inaccuracies, and copyright issues?
The webinar participants voice similar AI priorities in the coming year: building infrastructure to use these technologies at scale, equipping the workforce with training and resources, delivering AI capabilities that increase efficiencies, and establishing governance and risk management policies. The episode ends with a discussion of the near future, with each technology leader outlining their agency’s expected output and accomplishments regarding AI. At NASA, Salvagnini expects a perspective shift toward AI in our daily work. “I see an acceptance of AI as the digital assistant, that capability that is going to enable every member of the workforce to be more effective with their time.”
