Curiosity Blog, Sols 4709-4715: Drilling High and Low in the Boxwork Unit

Written by Catherine O’Connell-Cooper, APXS Strategic Planner and Payload Uplink/Downlink Lead, University of New Brunswick, Canada

Earth planning date: Friday, Nov. 7, 2025

We are in the most intensive phase of the boxwork structures investigation — the drill campaign. The boxwork campaign group requested a pair of drilled targets — one in a hollow (the topographic low) and one on an adjacent ridge, surrounding the hollow.

As we noted in a previous blog, finding a drill target in the hollows proved to be tricky, as the hollow floors are often covered by sand and pebbles, with minimal bedrock exposed. But over the past two weeks, we successfully drilled the bedrock target “Valle de la Luna” in a large hollow called “Monte Grande.” We finished up at Valle de la Luna on Monday and moved quickly up onto the ridge to get our second target, about 10 meters away (about 33 feet).

We wanted to name our targets to reflect the difference in location — from the topographic low to the (relatively speaking) high point on the nearby ridge. Our hollow target, Valle de la Luna, was named after an area of valleys in the Atacama Desert, in Chile. This area is one of the driest on Earth, with a unique environment and an incredible sculpted landscape with geological formations that would not look out of place in Gale crater.

Although there is a mere 2-meter difference in elevation (about 6½ feet) between the hollow floor and the ridge top, we decided to name our ridge target “Nevado Sajama,” which is an extinct volcano and the highest peak in Bolivia. Go big or go home!

Wednesday’s plan centered around our “Drill Sol Zero” activities. We use this day to finesse our position for drilling with a small drive (we refer to this kind of positioning drive as a “bump” as it is usually less than a couple of meters, which is less than 6 feet) to the most suitable potential drill target. On Wednesday, we bumped our way forward very slightly on the workspace, and this morning (Friday) the best potential target for drilling was in the perfect location. Today we do our Drill Sol 1 activities, which focus on triaging the Nevado Sajama bedrock block for drilling (the center of this Mastcam image; the lower block in this Navcam image). The Rover Planners (RPs) will test the coherency of the rock, to assess how it will hold up under the pressure of drilling. APXS and ChemCam will analyze the brushed bedrock in the intended drill area. We can compare this to targets from the very nearby Wednesday workspace (“Volcan Isluga” for APXS and “Luna Muerte” for ChemCam), so we can determine how homogenous or heterogenous this area is. MAHLI will image the bedrock here too, and again compare to targets from the Wednesday workspace (Volcan Isluga and the MAHLI-only target “Sipe Sipe,” which was an area of freshly broken rock, broken as we drove over it).

The drill campaign for the boxwork area has been two years in the planning. Over those years, the boxwork campaign focus group (including me) have had regular meetings and presentations and brainstorming sessions. It is so rewarding to finally be here, in the middle of this active drill campaign.

NASA Telescopes View Spiral Galaxy

NGC 1068, a relatively nearby spiral galaxy, appears in this image released on July 23, 2025. The galaxy contains a black hole at its center that is twice as massive as the Milky Way’s. NASA’s Chandra X-ray Observatory data shows a million-mile-per-hour wind is being driven from NGC 1068’s black hole and lighting up the center of the galaxy in X-rays.

The image contains X-rays from Chandra (blue), radio data from the U.S. National Science Foundation’s Karl G. Jansky Very Large Array (pink), and optical data from NASA’s Hubble Space Telescope and NASA’s James Webb Space Telescope (yellow, grey and gold).

Guiding Artemis: Brian Alpert Turns Lessons Learned Into Lunar Progress

Brian Alpert’s path was always destined for the aerospace industry, but his journey turned toward NASA’s Johnson Space Center during his sophomore year in college. That was when Tricia Mack, who works in NASA’s Transportation Integration Office within the International Space Station Program, spoke to his aerospace seminar about planning spacewalks, training crews, and supporting operations from the Mission Control Center in Houston.

Alpert was inspired to join the agency and later earned a spot as an engineering co-op student at Johnson. “My first stop after new employee orientation was Tricia’s office,” he said.

Eighteen years later, Alpert is the cross-program integration deputy for NASA’s human landing system (HLS) – the mode of transportation that will take astronauts to the lunar surface as part of the Artemis campaign. In his role, Alpert is responsible for coordinating with other Artemis programs, like the Orion Program, on issue resolution, joint agreements, data exchanges, hardware integration, and reviews. He also co-leads the Exploration Atmospheres Issue Resolution Team, assessing risks to and impacts on space vehicle atmosphere, spacesuit pressure, and operational timelines for Artemis missions.

Alpert has enjoyed the opportunity to participate in several proposal reviews for Artemis program contracts as well. “NASA’s model of embracing public-private partnerships to achieve its strategic goals and objectives is exciting and will continue to expand opportunities in space,” he said.

He applies lessons learned and skills gained from his previous roles as a spacewalk crew instructor, flight controller, and systems engineer to his current work on HLS. “I hope to pass on to the next generation that skills and lessons you learn as a student or a young employee can and will help you in your future work,” he said.

Alpert’s prior NASA roles involved memorable experiences like working to address spacesuit and vehicle failures that occurred during a spacewalk on International Space Station Expedition 32. He was serving as the lead spacewalk systems flight controller in the Mission Control Center at the time and played a key role in getting NASA astronaut Suni Williams and JAXA (Japan Aerospace Exploration Agency) astronaut Aki Hoshide safely back aboard the space station. Since Williams and Hoshide did not complete the spacewalk’s primary objective – replacing a Main Bus Switching Unit – a backup spacewalk was scheduled several days later. Alpert was on console for that spacewalk, too.

“One important lesson that I have learned through my career to date is how exceptionally talented, passionate, and hard-working everyone is here at NASA,” he said. “Whenever work gets stressful or problems get hard, there are teams of people that have your back, are willing to problem-solve with you, and can bring another perspective to finding a solution that you may not have considered.” He added that his colleagues are the best part of his job. “As much as I love what we do at NASA, what really gets me excited to come to work is all the outstanding people I get to work with every day.”

Learning how to navigate change has been an important lesson for Alpert, as well. “NASA has been through a lot of change since I became a full-time employee in 2009,” he said. “Making sure that I have clear goals for myself, my work, and my team helps us all stay focused on the mission and the work at hand and helps us prioritize projects and tasks as questions or challenges inevitably arise.”

One challenge Alpert especially enjoys? Johnson’s annual Chili Cookoff. He has participated in many cookoffs as part of the Cosmic Chili team, noting that he often dons a Wolverine costume as part of the festive fun. He also welcomes a space trivia challenge – and a chance to add to his collection of trivia trophies.
