Sols 4561-4562: Prepping to Drill at Altadena

Written by Conor Hayes, Graduate Student at York University

Earth planning date: Wednesday, June 4, 2025

We are continuing to look for a suitable location to collect a drilled sample in this area. As you may recall from Monday’s plan, we performed a short “bump” of just under 4 meters (about 13 feet) hoping to find a drill target today after Monday’s analysis determined that there were no good targets in our previous workspace. Happily, today’s workspace was much more cooperative, and we were able to select the target “Altadena” as our next potential drill location. Altadena is a name that we’ve been saving for a special target, as its namesake here on Earth is a neighborhood next to JPL that was devastated by the Eaton Fire earlier this year. We’re about to enter our next mapping quadrangle, which will come with a new set of target names, so the team decided that using Altadena as the name for this drill site was an obvious choice.

The big activity in this plan is the next step in the drilling process. This activity is the “preload test,” which determines if the forces on the drill will be good while drilling, and the drill target won’t unexpectedly move or fracture. If we pass the preload test and find that the rock has the chemistry we’re looking for, we’ll be able to proceed with Altadena as our next drill site. If we don’t, we’ll have to decide whether to bump again or resume driving deeper into this potentially boxwork-bearing region.

Of course, the preload test isn’t the only thing we’re doing today. Coming in, it was looking like our time for other activities would be pretty tight due to power constraints imposed by preparations for drilling and keeping the rover warm during the cold Martian winter. However, we’ve recently implemented some new power-optimizing capabilities, which led to us having much more power today than we expected. This meant that we were able to add a whole additional hour of science time in addition to the hour that we already had scheduled. 

Unsurprisingly, Altadena gets a lot of love in this plan to characterize it before we drill. This includes a ChemCam LIBS activity and a Mastcam observation, as well as some overnight observations by APXS and some MAHLI images. In addition, Mastcam will be observing some exposed stratigraphy at “Dana Point,” a light-toned vein at “Mission Trails” that will also be a ChemCam LIBS target, a few more nearby troughs, and a couple of sandy patches at “Camp Williams” to observe wind-driven sediment transport. Along with the two LIBS, ChemCam will be using its RMI camera to add to the pile of images we have of the Mishe Mokwa butte and the yardang unit off in the distance.

As the lead for the Atmosphere and Environment (ENV) group today, it looked like I was going to have a pretty light workload due to the power constraints preventing any ENV activities other than our usual REMS, RAD, and DAN observations. With the extra hour of science time, I was able to add a handful of new activities, including three Navcam cloud movies, a Navcam line-of-sight observation of dust within Gale Crater, and a Navcam survey to look for any dust devils that may be swirling around the rover. A pretty decent ENV science haul for a plan that started with nothing!

When we come into planning on Friday, we’ll hopefully have passed the preload test and will be able to turn Altadena into our 43rd drill hole in the coming sols, before we continue driving up the slopes of Mount Sharp.

Searching for Ancient Rocks in the ‘Forlandet’ Flats

Written by Henry Manelski, Ph.D. student at Purdue University

This week Perseverance continued its gradual descent into the relatively flat terrain outside of Jezero Crater. In this area, the science team expects to find rocks that could be among the oldest ever observed by the Perseverance rover — and perhaps any rover to have explored the surface of Mars — presenting a unique opportunity to understand Mars’ ancient past. Perseverance is now parked at “Fallbreen,” a light-toned bedrock exposure that the science team hopes to compare to the nearby olivine-bearing outcrop at “Copper Cove.” This could be a glimpse of the geologic unit rich in olivine and carbonate that stretches hundreds of kilometers to the west of Jezero Crater. Gaining insight into how these rocks formed could have profound implications for our constantly evolving knowledge of this region’s history. Perseverance’s recent traverses marked another notable transition. After rolling past Copper Cove, Perseverance entered the “Forlandet” quadrangle, a 1.2-square-kilometer (about 0.46 square mile, or 297-acre) area along the edge of the crater that the science team named after Forlandet National Park on the Norwegian archipelago of Svalbard. Discovered in the late 16^th century by Dutch explorers, this icy set of islands captured the imagination of a generation of sailors searching for the Northwest Passage. While Perseverance is in the Forlandet quad, landforms and rock targets will be named informally after sites in and around this national park on Earth. As the rover navigates through its own narrow passes in the spirit of discovery, driving around sand dunes and breezing past buttes, we hope it channels the perseverance of the explorers who once gave these rocks their names.

Webb Sees Sombrero Galaxy in Near-Infrared

After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared. In the newest image, released on June 3, 2025, the Sombrero galaxy’s tightly packed group of stars at the galaxy’s center is illuminated while the dust in the outer edges of the disk blocks some stellar light. Studying galaxies like the Sombrero at different wavelengths, including the near-infrared and mid-infrared with Webb, as well as the visible with NASA’s Hubble Space Telescope, helps astronomers understand how this complex system of stars, dust, and gas formed and evolved, along with the interplay of that material.

NASA Mars Orbiter Captures Volcano Peeking Above Morning Cloud Tops

The 2001 Odyssey spacecraft captured a first-of-its-kind look at Arsia Mons, which dwarfs Earth’s tallest volcanoes.

A new panorama from NASA’s 2001 Mars Odyssey orbiter shows one of the Red Planet’s biggest volcanoes, Arsia Mons, poking through a canopy of clouds just before dawn. Arsia Mons and two other volcanoes form what is known as the Tharsis Montes, or Tharsis Mountains, which are often surrounded by water ice clouds (as opposed to Mars’ equally common carbon dioxide clouds), especially in the early morning. This panorama marks the first time one of the volcanoes has been imaged on the planet’s horizon, offering the same perspective of Mars that astronauts have of the Earth when they peer down from the International Space Station.

Launched in 2001, Odyssey is the longest-running mission orbiting another planet, and this new panorama represents the kind of science the orbiter began pursuing in 2023, when it captured the first of its now four high-altitude images of the Martian horizon. To get them, the spacecraft rotates 90 degrees while in orbit so that its camera, built to study the Martian surface, can snap the image.

The angle allows scientists to see dust and water ice cloud layers, while the series of images enables them to observe changes over the course of seasons.

“We’re seeing some really significant seasonal differences in these horizon images,” said planetary scientist Michael D. Smith of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s giving us new clues to how Mars’ atmosphere evolves over time.”

Understanding Mars’ clouds is particularly important for understanding the planet’s weather and how phenomena like dust storms occur. That information, in turn, can benefit future missions, including entry, descent and landing operations.

Volcanic Giants

While these images focus on the upper atmosphere, the Odyssey team has tried to include interesting surface features in them, as well. In Odyssey’s latest horizon image, captured on May 2, Arsia Mons stands 12 miles (20 kilometers) high, roughly twice as tall as Earth’s largest volcano, Mauna Loa, which rises 6 miles (9 kilometers) above the seafloor.

The southernmost of the Tharsis volcanoes, Arsia Mons is the cloudiest of the three. The clouds form when air expands as it blows up the sides of the mountain and then rapidly cools. They are especially thick when Mars is farthest from the Sun, a period called aphelion. The band of clouds that forms across the planet’s equator at this time of year is called the aphelion cloud belt, and it’s on proud display in Odyssey’s new panorama.

“We picked Arsia Mons hoping we would see the summit poke above the early morning clouds. And it didn’t disappoint,” said Jonathon Hill of Arizona State University in Tempe, operations lead for Odyssey’s camera, called the Thermal Emission Imaging System, or THEMIS.

The THEMIS camera can view Mars in both visible and infrared light. The latter allows scientists to identify areas of the subsurface that contain water ice, which could be used by the first astronauts to land on Mars. The camera can also image Mars’ tiny moons, Phobos and Deimos, allowing scientists to analyze their surface composition.
