Sols 4416-4417: New Year, New Clouds
NASA’s Mars rover Curiosity captured this image of noctilucent clouds using its Right Navigation Camera on sol 4401 — or Martian day 4,401 of the Mars Science Laboratory mission — on Dec. 23, 2024, at 08:57:15 UTC. NASA/JPL-Caltech Earth planning date: Monday, Jan. 6, 2025
After our marathon holiday plan, we’re easing back into the new year with a standard two-sol plan. We did arrive today to the news that the drive hadn’t made it as far as we wanted, but luckily the rover planners determined that we were still in a good position to do contact science on two wintry targets — “Snow Creek” and “Winter Creek.” We also packed in lots of remote science with ChemCam using LIBS on “Grapevine” and “Skull Rock,” and we are doing long-distance imaging of the Texoli and Wilkerson buttes, and Gould Mesa. Mastcam will be imaging a number of targets near and far as well including “Red Box”’ “Point Mugu,” “Stone Canyon,” “Pine Cove,” and “Hummingbird Sage,” which will examine various structures in the bedrock. We can’t forget about the atmosphere either — we have a couple dust-devil surveys to look for dust lifting, but the real star of the show (at least for me) is the cloud imaging.
While we’re just into 2025 here on Earth, we’re also near the start of a new year on Mars! A Mars year starts at the northern vernal equinox (or the start of autumn in the southern hemisphere, where Curiosity is), and Mars year 38 started on Nov. 12.
We’re about a third of the way through autumn on Mars now, and the southern Martian autumn and winter bring one thing — clouds! Near the start of the Martian year we start seeing clouds around sunset. These are noctilucent (meaning “night illuminated”) clouds. Even though the sun has set in Gale Crater, the clouds are high enough in the atmosphere that the sun still shines on them, making them seem to almost glow in the sky. You can see this with clouds on Earth, too, around twilight! Mars year 38 will be our fourth year capturing these twilight clouds, and the Navcam images (one of which you can see above) already show it’s shaping up to be another year of spectacular clouds!

What are the chances of four iconic landmarks being struck by lightning on the same day?
On December 31, 2024, an extraordinary series of lightning strikes hit four major landmarks: the U.S. Capitol Building and the Washington Monument in Washington, D.C., along with the Empire State Building and One World Trade Center in New York City.
The lightning strikes occurred during intense rainstorms along the East Coast, coinciding with New Year's Eve celebrations. The rare phenomenon quickly ignited a flurry of speculation on social media, with many users interpreting the event as symbolic. Some called it a potential omen, asking: "Is this a sign? What could it mean?" View the full article

Astronomy Activation Ambassadors: A New Era
The NASA Science Activation Program’s Astronomy Activation Ambassadors (AAA) project aims to measurably enhance student Science, Technology, Engineering, and Mathematics (STEM) engagement via middle school, high school, and community college science teacher professional development.
In 2024, AAA transitioned its focus to the development of an Astronomy Academy with varying levels of extent and intensity available to more than 300 teachers per year. Participants draw on NASA resources and Subject Matter Experts (SME) to enhance their teaching and help share their excitement about astronomy with their students. The three strands that comprise the Astronomy Academy are:
webinars regarding NASA astrophysics and planetary science content and facilities, curriculum workshops enabling classroom use of an electromagnetic spectrum and multi-wavelength astronomy (EMS/MWA) curriculum, and STEM immersion experiences including guided visits to working observatories. The first two of the AAA program’s new type of STEM immersion experiences took place in June and September, 2024. During the weekend of June 22-23, 19 teachers gathered in San Jose, California for a full agenda, including:
NASA SME presentations regarding planetary protection and exoplanet detection, a journey to the University of California’s Lick Observatory on nearby Mt. Hamilton for an in-depth guided tour of the observatory’s astronomy research facilities, which included engagement with the astronomers using the 3-meter Shane telescope, and a 4-hour hands-on EMS/MWA curriculum teaching workshop. A similar STEM immersion sequence was offered September 14-15 to 23 AAA teachers who attended a curriculum teaching workshop, learned about current infrared astronomy research from NASA Jet Propulsion Laboratory scientists, and received guided visits to the Keck Observatory’s remote observing facility on the Caltech campus and the Mt. Wilson Observatory, including a half-night’s reserved use of the historic Mt. Wilson 60-inch telescope. The teachers were invited to submit a list of objects to be observed with the Mt. Wilson telescope and viewed a wonderful array of star clusters, colorful double stars, and galaxies, with a grand finale view of Saturn and its rings.
Teacher participant, Domina Stamas (Westlake Charter School, Sacramento, California), had this to say: “My students and I are already benefiting greatly from the combination of NASA resources, science content, and curricular materials we have received from the AAA project. The evening at Lick Observatory talking with the astronomers who were using the research telescopes watching the laser guide star setup in action was a rich experience. I can convey to my students how scientists actually practice their craft.”
The Astronomy Activation Ambassador project’s efforts to improve student STEM learning and engagement via science teacher professional development are detailed at: https://www.seti.org/aaa
Educator enrollment is still open via the participant registration form:
