Sols 4511-4512: Low energy after a big weekend?

Earth planning date: Monday, April 14, 2025
We all know the feeling: it’s Monday morning after a big weekend and you’re coming into the week wishing you’d had a little more time to rest and recharge. Well, Curiosity probably feels the same way today. Curiosity accomplished a lot over the weekend, including full contact science, a MAHLI stereo imaging test, testing the collection of ChemCam passive spectral data at the same time as data transmission with one of the orbiters, and some APXS and MAHLI calibration target activities, plus a long 57 m drive. It was great to see all of those activities in the plan and to see some great drive progress. But that means we’re a bit tight on power for today’s plan!
I was on shift as Long Term Planner today, and the team had to think carefully about science priorities to fit within our power limit for today’s plan, and how that will prepare us for the rest of the week. The team still managed to squeeze a lot of activities into today’s 2-sol plan. First, Curiosity will acquire Mastcam mosaics to investigate local stratigraphic relationships and diagenetic features. Then we’ll acquire some imaging to document the sandy troughs between bedrock blocks to monitor active surface processes. We’ll also take a Navcam mosaic to assess atmospheric dust. The science block includes a ChemCam LIBS observation on the bedrock target “Santa Margarita” and a long distance RMI mosaic of “Ghost Mountain” to look for possible boxwork structures. Then Curiosity will use the DRT, APXS and MAHLI to investigate the finely-laminated bedrock in our workspace at a target named “The Grotto.” We’ll also collect APXS and MAHLI data on a large nodule in the workspace named “Torrey Pines” (meanwhile the Torrey Pines here on Earth was shaking in today’s southern California earthquakes! All is well but it gave some of our team members an extra jolt of adrenaline right before the SOWG meeting). The second sol is focused on continuing our drive to the south and taking post-drive imaging to prepare for Wednesday’s plan.
Phew! Good job Curiosity, you made it through Monday.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
From left, Ramon Pedoto, Nathan Walkenhorst, and Tyrell Jemison review information at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The three team members developed new automation tools at Marshall for flight controllers working with the International Space Station (Credit: NASA/Tyrell Jemison Two new automation tools developed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are geared toward improving operations for flight controllers working with the International Space Station from the Huntsville Operations Support Center.
The tools, called AutoDump and Permanently Missing Intervals Checker, will free the flight control team to focus on situational awareness, anomaly response, and real-time coordination.
The space station experiences routine loss-of-signal periods based on communication coverage as the space station orbits the Earth. When signal is lost, an onboard buffer records data that could not be downlinked during that period. Following acquisition of signal, flight controllers previously had to send a command to downlink, or “dump,” the stored data.
The AutoDump tool streamlines a repetitive data downlinking command from flight controllers by detecting a routine loss-of-signal, and then autonomously sending the command to downlink data stored in the onboard buffer when the signal is acquired again. Once the data has been downlinked, the tool will automatically make an entry in the console log to confirm the downlink took place.
“Reliably and quickly sending these dump commands is important to ensure that space station payload developers can operate from the most current data,” said Michael Zekoff, manager of Space Systems Operations at Marshall.
As a direct result of this tool, we have eliminated the need to manually perform routine data dump commands by as much as 40% for normal operations.

Space Systems Operations Manager
AutoDump was successfully deployed on Feb. 4 in support of the orbiting laboratory.
The other tool, known as the Permanently Missing Intervals Checker, is another automated process coming online that will improve team efficiency.
Permanently missing intervals are gaps in the data stream where data can be lost due to a variety of reasons, including network fluctuations. The missing intervals are generally short but are documented so the scientific community and other users have confirmation that the missing data is unable to be recovered.
“The process of checking for and documenting permanently missing intervals is challenging and incredibly time-consuming to make sure we capture all the payload impacts,” said Nathan Walkenhorst, a NASA contractor with Bailey Collaborative Solutions who serves as a flight controller specialist.
The checker will allow NASA to quickly gather and assess payload impacts, reduce disruptions to operations, and allow researchers to get better returns on their science investigations. It is expected to be deployed later this year.
In addition to Walkenhorst, Zekoff also credited Ramon Pedoto, a software architect, and Tyrell Jemison, a NASA contractor and data management coordinator with Teledyne Brown Engineering Inc, for their work in developing the automation tools. The development of the tools also requires coordination between flight control and software teams at Marshall, followed by extensive testing in both simulated and flight environments, including spacecraft operations, communications coverage, onboard anomalies, and other unexpected conditions.
“The team solicited broad review to ensure that the tool would integrate correctly with other station systems,” Zekoff said. “Automated tools are evaluated carefully to prevent unintended commanding or other consequences. Analysis of the tools included thorough characterization of the impacts, risk mitigation strategies, and approval by stakeholders across the International Space Station program.”
The Huntsville Operations Support Center provides payload, engineering, and mission operations support to the space station, the Commercial Crew Program, and Artemis missions, as well as science and technology demonstration missions. The Payload Operations Integration Center within the Huntsville Operations Support Center operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day.

NASA’s Juno Back to Normal Operations After Entering Safe Mode
NASA’s Juno flies above Jupiter’s Great Red Spot in this artist’s concept. NASA/JPL-Caltech The spacecraft was making its 71st close approach to Jupiter when it unexpectedly entered into a precautionary status.
Data received from NASA’s Juno mission indicates the solar-powered spacecraft went into safe mode twice on April 4 while the spacecraft was flying by Jupiter. Safe mode is a precautionary status that a spacecraft enters when it detects an anomaly. Nonessential functions are suspended, and the spacecraft focuses on essential tasks like communication and power management. Upon entering safe mode, Juno’s science instruments were powered down, as designed, for the remainder of the flyby.
The mission operations team has reestablished high-rate data transmission with Juno, and the spacecraft is currently conducting flight software diagnostics.The team will work in the ensuing days to transmit the engineering and science data collected before and after the safe-mode events to Earth.
Juno first entered safe mode at 5:17 a.m. EDT, about an hour before its 71st close passage of Jupiter — called perijove. It went into safe mode again 45 minutes after perijove. During both safe-mode events, the spacecraft performed exactly as designed, rebooting its computer, turning off nonessential functions, and pointing its antenna toward Earth for communication.
Of all the planets in our solar system, Jupiter is home to the most hostile environment, with the radiation belts closest to the planet being the most intense. Early indications suggest the two Perijove 71 safe-mode events occurred as the spacecraft flew through these belts. To block high-energy particles from impacting sensitive electronics and mitigate the harmful effects of the radiation, Juno features a titanium radiation vault.
Including the Perijove 71 events, Juno has unexpectedly entered spacecraft-induced safe mode four times since arriving at Jupiter in July 2016: first, in 2016 during its second orbit, then in 2022 during its 39th orbit. In all four cases, the spacecraft performed as expected and recovered full capability.
Juno’s next perijove will occur on May 7 and include a flyby of the Jovian moon Io at a distance of about 55,300 miles (89,000 kilometers).

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Portrait of David Mitchell, Thursday, Jan. 27, 2022, NASA Headquarters Mary W. Jackson building in Washington.NASA/Bill Ingalls David Mitchell, the Associate Administrator for MSD.
Have you ever wondered how NASA manages to achieve all the incredible missions it does, like probing the Sun and studying the history of our Universe? We do it through teamwork, one of our core values. And an essential part of NASA’s team is what we call Mission Support. Mission Support makes sure NASA’s missions, centers, and programs have the capabilities and services they need to explore the unknown, innovate for the future, and inspire the world.
To illustrate Mission Support at NASA, look at the example of the Roman Space Telescope. It’s not just scientists and engineers who are making the telescope happen. The program works with NASA’s financial office to plan the budget for the telescope. Engineers design the telescope with tools developed in coordination with NASA’s shared services and information technology offices. NASA’s engineering authority checks the design, and international relations manages NASA’s collaborations with other countries on the telescope. All of this is Mission Support.
Of course, there is much more to Mission Support, but I think you get the picture. MSD enables Mission Support by:
Planning and executing the Mission Support budgets for safety, security, and mission services as well as construction and environmental management. Executing strategy and governance to ensure Mission Support is financially sound, aligned with the agency’s goals, and serving NASA’s missions. Addressing Mission Support’s financial, operational, legal, and reputational risks to ensure resilience and mission success. Working with mission directorates and centers to ensure NASA is prioritizing the Mission Support services they need most urgently to be successful. Integrating Mission Support services across the agency to maximize efficiency and effectiveness. Current and future missions require significant support to be successful. MSD is working today to ensure Mission Support is there for NASA to explore the unknown, innovate for the future, and inspire the world.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The International Space Station is pictured from the SpaceX Dragon spacecraft by a Crew-8 member shortly after undocking from the Harmony module’s space-facing port as the orbital outpost was soaring 272 miles above the cloudy Patagonia region of South America.NASA NASA is seeking proposals for two new private astronaut missions to the International Space Station, targeted for 2026 and 2027, as the agency continues its commitment to expanding access to space. These private missions enable American commercial companies to further develop capabilities and support a continuous human presence in low Earth orbit.
“We are in an incredible time for human spaceflight, with more opportunities to access space and grow a thriving commercial economy in low Earth orbit,” said Dana Weigel, program manager for the International Space Station at NASA’s Johnson Space Center in Houston. “NASA remains committed to supporting this expansion by leveraging our decades of expertise to help industry gain the experience needed to train and manage crews, conduct research, and develop future destinations. Private astronaut missions are a key part of this effort, providing companies with hands-on opportunities to refine their capabilities and build partnerships that will shape the future of low Earth orbit.”
The new flight opportunities will be the fifth and sixth private astronaut missions to the orbiting laboratory coordinated by NASA. The first three missions were accomplished by Axiom Space in April 2022, May 2023, and January 2024, with a fourth scheduled for no earlier than May 2025.
Each of the new missions may be docked to the space station for up to 14 days. Specific dates depend on spacecraft traffic at the space station and in-orbit activity planning and constraints. Private astronaut missions must be brokered by a U.S. entity and use U.S. transportation spacecraft that meet NASA’s International Space Station visiting vehicle requirements, policies, and procedures. For additional details, refer to Focus Area 4A of NASA Research Announcement (NRA) NNJ13ZBG001N.
Proposals are due by 5 p.m. EDT on Friday, May 30, 2025.
