This effort will leverage the latest developments in superconductors to build a power transmission cable that can operate in the extreme cold temperatures found on the Moon with very low electrical losses. The team will use novel manufacturing techniques to grow alternating layers of FeSe SrTiO3 films onto a substrate and the resulting, superconducting tape can be fashioned into electrical transmission lines. The project will culminate with a demonstration 1-meter-long superconducting transmission line which supports 1 amp of power transmission at 1,000 volts.

This project will develop piezoelectric-based power conversion for small power systems on the lunar surface. These piezoelectric systems can potentially offer high power density to significantly reduce size, weight, and cost. They can also offer high efficiency as well as resistance to the extreme lunar environment with its expected prolonged exposure to extreme cold and radiation. The effort will build and test prototype piezoelectric DC-to-DC power converters and DC-to-DC power supplies.

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.

Exploring the unknown and preparing for humanity’s next giant leap really works up an appetite. Thankfully, employees at NASA’s Johnson Space Center in Houston can count on Tina Preyan to help them fuel up and stay focused.
Preyan is a food service specialist at Starport, a quality-of-life program that contributes to Johnson’s mission by providing employee services and activities that enhance work life and promote mental well-being and physical fitness. Part of the agency’s network of 12 NASA Exchanges — each located at a NASA center or facility — Starport offers everything from group fitness classes to retail shopping, with programs designed to engage, energize, and support the workforce.
Tina Preyan supports a NASA Exchange display at a Johnson Space Center event. Image courtesy of Tina Preyan Preyan oversees the on-site dining options at Johnson, from its cafés and food trucks to vending machines and mini markets. She helps set the budget for food services, creates monthly calendars of food offerings, schedules vendors and pop-up events, and ensures annual food safety inspections are conducted. She also works with teams across Johnson to order food and related supplies for NASA events.
“The best part of my job is working in customer service, meeting new NASA workers every day, and making everyone feel welcome and at home when coming to Johnson’s cafés,” she said.
Preyan has been a fixture at Johnson for the last 19 years. She previously worked at NASA’s Michoud Assembly Facility in New Orleans but transferred to Houston shortly after Hurricane Katrina hit the city in 2005. At Starport, she worked her way up from prep cook to lead cashier and then to lead assistant. She also served as the office’s administrative assistant before transitioning to her current role.
Tina Preyan poses for a photo with NASA astronauts Jessica Watkins and Victor Glover. Image courtesy of Tina Preyan Preyan has enjoyed meeting many NASA astronauts and Johnson team members and learning more about the work they do. The occasional celebrity sighting is another job perk.
Preyan is something of a celebrity herself. “So many employees know my name. I am proud of meeting so many people, and the love they give me every day just being here,” she said.
She was also proud to receive Starport’s Jackie Kingery Award in fall 2024. The award recognizes extraordinary customer service and exemplary dedication to the NASA Exchange mission at Johnson. “It felt amazing to receive this award and know that I am doing a great job in everyone’s eyes,” she said. “I value high integrity and am always willing to help others in the organization.”

Her son, Cameron, who is set to graduate from the University of Texas at San Antonio in May with a degree in Finance and Marketing.
In addition to her son’s graduation, Preyan looks forward to continuing her work in a positive environment and pursuing more growth opportunities.
“I’m going to stay busy and stay focused on ensuring proper procedures are being used by vendors,” she said. “And making sure all customers are happy and will continue to return to cafés.”
