Persevering Through the Storm
A region-wide seasonal dust storm obscures the Jezero Crater in this image from NASA’s Mars Perseverance rover, acquired using its Left Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. Perseverance captured the image on Aug. 20, 2024 (Sol 1244, or Martian day 1,244 of the Mars 2020 mission) at the local mean solar time of 16:05:34. This image is part of a Mastcam-Z mosaic of the “northern fan,” a part of Jezero Crater that Perseverance never drove through, but is an area that’s thought to have been deposited in a similar way to the delta that the rover did explore. NASA/JPL-Caltech/ASU It is dust-storm season on Mars! Over the past couple of weeks, as we have been ascending the Jezero Crater rim, our science team has been monitoring rising amounts of dust in the atmosphere. This is expected: Dust activity is typically highest around this time of the Martian year (early Spring in the northern hemisphere). The increased dust has made our views back toward the crater hazier than usual, and provided our atmospheric scientists with a great opportunity to study the way that dust storms form, develop, and spread around the planet.
Perseverance has a suite of scientific instruments well-suited to study the Martian atmosphere. The Mars Environmental Dynamics Analyzer (MEDA) provides regular weather reports, the cadence of which has increased during the storm to maximize our science. We also routinely point our Mastcam-Z imager toward the sky to assess the optical density (“tau”) of the atmosphere.
There are not any signs that this regional dust storm will become planetwide — like the global dust storm in 2018 — but every day we are assessing new atmospheric data. Hopefully the skies will further clear up as we continue to climb in the coming weeks, because we are expecting stunning views of the crater floor and Jezero delta. This will offer the Perseverance team a unique chance to reflect on the tens of kilometers we have driven and years we have spent exploring Mars together.

September brings the gas giants Jupiter and Saturn back into view, along with their satellites. And while we organize celebrations to observe our own Moon this month, be sure to grab a telescope or binoculars to see other moons within our Solar System! We recommend observing these moons (and planets!) when they are at their highest in the night sky, to get the best possible unobstructed views.
The More the Merrier
As of September 2024, the ringed planet Saturn has 146 identified moons in its orbit. These celestial bodies range in size; the smallest being a few hundred feet across, to Titan, the second largest moon in our solar system.
The Saturnian system along with various moons around the planet Saturn: Iapetus, Titan, Enceladus, Rhea, Tethys, and Dione. Stellarium Web Even at nearly 900 million miles away, Titan can be easily spotted next to Saturn with a 4-inch telescope, under urban and suburban skies, due to its sheer size. With an atmosphere of mostly nitrogen with traces of hydrogen and methane, Titan was briefly explored in 2005 with the Huygens probe as part of the Cassini-Huygens mission, providing more information about the surface of Titan. NASA’s mission Dragonfly is set to explore the surface of Titan in the 2030s.
Enceladus is an icy world much like Hoth, except that it has an ocean under its frozen crust. Astronomers believe this moon of Saturn may be a good candidate for having extraterrestrial life beneath its surface. NASA/ESA/JPL-Caltech/Space Science Institute Saturn’s moon Enceladus was also explored by the Cassini mission, revealing plumes of ice that erupt from below the surface, adding to the brilliance of Saturn’s rings. Much like our own Moon, Enceladus remains tidally locked with Saturn, presenting the same side towards its host planet at all times.
The Galilean Gang
The King of the Planets might not have the most moons, but four of Jupiter’s 95 moons are definitely the easiest to see with a small pair of binoculars or a small telescope because they form a clear line. The Galilean Moons – Ganymede, Callisto, Io, and Europa – were first discovered in 1610 and they continue to amaze stargazers across the globe.
The Jovian system: Europa, Io, Ganymede, and Callisto. Stellarium Web Ganymede: largest moon in our solar system, and larger than the planet Mercury, Ganymede has its own magnetic field and a possible saltwater ocean beneath the surface. Callisto: this heavily cratered moon is the third largest in our solar system. Although Callisto is the furthest away of the Galilean moons, it only takes 17 days to complete an orbit around Jupiter. Io: the closest moon and third largest in this system, Io is an extremely active world, due to the push and pull of Jupiter’s gravity. The volcanic activity of this rocky world is so intense that it can be seen from some of the largest telescopes here on Earth. Europa: Jupiter’s smallest moon also happens to be the strongest candidate for a liquid ocean beneath the surface. NASA’s Europa Clipper is set to launch October 2024 and will determine if this moon has conditions suitable to support life. Want to learn more? Rewatch the July 2023 Night Sky Network webinar about Europa Clipper here. Be sure to celebrate International Observe the Moon Night here on Earth September 14, 2024, leading up to the super full moon on September 17th! You can learn more about supermoons in our mid-month article on the Night Sky Network page!

Eclipse Soundscapes AudioMoth Donations Will Study Nature at Night
During the April 8, 2024 total solar eclipse, approximately 770 AudioMoth recording devices were used to capture sound data as part of the Eclipse Soundscapes Project — a multisensory participatory science (also known as “citizen science”) project that is studying how eclipses impact life on Earth. Following the eclipse, participants had the option to keep or send back their AudioMoth device for donation. Fifty-two AudioMoths were sent back to Eclipse Soundscapes (ES) so that ES could donate them to projects or communities for future scientific usage. Eighteen of those AudioMoths have been donated to Dark Sky Missouri, an initiative to protect our night skies and the creatures that depend on them. On Wednesday, August 21, 2024, at 3 p.m. EST, Eclipse Soundscapes hosted a webinar with Dark Sky Missouri founder Don Ficken to learn more about how these AudioMoths will contribute to future participatory science.
Don Ficken is a Missouri Master Naturalist and amateur astronomer who found the Eclipse Soundscapes Project through SciStarter, an organization that helps bring together millions of curious and concerned people in the world to engage in real-world research questions through citizen science. He participated as a Data Collector in 2024. “[The Eclipse Soundscapes Project] opened up a door for me because I never really thought about sound acoustics in this way,” Ficken said.
It occurred to Ficken that acoustics could help bolster Dark Sky Missouri’s efforts to study and conserve night time wildlife. One of these efforts, Lights Out Heartland, encourages homeowners and businesses to minimize artificial light usage in order to protect migrating birds from collisions due to disorienting bright lights. Ficken hopes to use the AudioMoths to capture the birds’ nocturnal flight calls as they fly over locations like the Gateway Arch, Shaw Nature Reserve, and Missouri Botanical Gardens.
Dark Sky Missouri also hopes to take more general surveys of nature at night by placing AudioMoths in parks and natural areas. Even though parks are not typically open or staffed at night, the AudioMoths could help map the locations and movements of wildlife, creating talking points and learning opportunities for staff and visitors alike.
Both initiatives will be piloted during the fall bird migration, with the goal of developing a framework for an expanded long term project. While there are no opportunities for the general public to get involved in the projects just yet, Ficken says participatory scientists can benefit from the multisensory methods employed in the Eclipse Soundscapes Project. “I think that the thing that they should think about is really the door that acoustics would be opening for them,” he said. “In other words, you don’t have to just visually look at daytime. Think about sound. Think about night.” For more information on how Dark Sky Missouri will use the AudioMoth recorders, read the Eclipse Soundscapes blog post.
The Eclipse Soundscapes Project is supported by NASA under cooperative agreement award number 80NSSC21M0008 and is part of NASA’s Science Activation Portfolio.

Dark Sky Missouri will use the donated Eclipse Soundscapes AudioMoths to study bird calls and behavior at night. Share
