California Teams Win $1.5 Million in NASA’s Break the Ice Lunar Challenge

By Savannah Bullard

After two days of live competitions, two teams from southern California are heading home with a combined $1.5 million from NASA’s Break the Ice Lunar Challenge. 

Since 2020, competitors from around the world have competed in this challenge with the common goal of inventing robots that can excavate and transport the icy regolith on the Moon. The lunar South Pole is the targeted landing site for crewed Artemis missions, so utilizing all resources in that area, including the ice within the dusty regolith inside the permanently shadowed regions, is vital for the success of a sustained human lunar presence.

On Earth, the mission architectures developed in this challenge aim to help guide machine design and operation concepts for future mining and excavation operations and equipment for decades.

“Break the Ice represents a significant milestone in our journey toward sustainable lunar exploration and a future human presence on the Moon,” said Joseph Pelfrey, Center Director of NASA’s Marshall Space Flight Center. “This competition has pushed the boundaries of what is possible by challenging the brightest minds to devise groundbreaking solutions for excavating lunar ice, a crucial resource for future missions. Together, we are forging a future where humanity ventures further into the cosmos than ever before.”

The final round of the Break the Ice competition featured six finalist teams who succeeded in an earlier phase of the challenge. The competition took place at the Alabama A&M Agribition Center in Huntsville, Alabama, on June 11 and 12, where each team put their diverse solutions to the test in a series of trials, using terrestrial resources like gravity-offloading cranes, concrete slabs, and a rocky track with tricky obstacles to mimic the environment on the Moon.

The husband-and-wife duo of Terra Engineering took home the top prize for their “Irresistible Object” rover. Team lead Todd Mendenhall competed in NASA’s 2007 Regolith Excavation Challenge, facilitated through NASA’s Centennial Challenges, which led him and Valerie Mendenhall to continue the pursuit of solutions for autonomous lunar excavation.

A small space hardware business, Starpath Robotics, earned the second-place prize for its four-wheeled rover that can mine, collect, and haul material. The team, led by Saurav Shroff and lead engineer Mihir Gondhalekar, developed a robotic mining tool that features a drum barrel scraping mechanism for breaking into the tough lunar surface. This allows the robot to mine material quickly and robustly without sacrificing energy.

“This challenge has been pivotal in advancing the technologies we need to achieve a sustained human presence on the Moon,” said Kim Krome, the Acting Program Manager for NASA’s Centennial Challenges. “Terra Engineering’s rover, especially, bridged several of the technology gaps that we identified – for instance, being robust and resilient enough to traverse rocky landscapes and survive the harsh conditions of the lunar South Pole.”

Beyond the $1.5 million in prize funds, three teams will be given the chance to use Marshall Space Flight Center’s thermal vacuum (TVAC) chambers to continue testing and developing their robots. These chambers use thermal vacuum technologies to create a simulated lunar environment, allowing scientists and researchers to build, test, and approve hardware for flight-ready use.

The following teams performed exceptionally well in the excavation portion of the final competition, earning these invitations to the TVAC facilities:

• Terra Engineering (Gardena, California)
• Starpath Robotics (Hawthorne, California)
• Michigan Technological University – Planetary Surface Technology Development Lab (Houghton, Michigan)

“We’re looking forward to hosting three of our finalists at our thermal vacuum chamber, where they will get full access to continue testing and developing their technologies in our state-of-the-art facilities,” said Break the Ice Challenge Manager Naveen Vetcha, who supports NASA’s Centennial Challenges through Jacobs Space Exploration Group. “Hopefully, these tests will allow the teams to take their solutions to the next level and open the door for opportunities for years to come.”

NASA’s Break the Ice Lunar Challenge is a NASA Centennial Challenge led by the agency’s Marshall Space Flight Center, with support from NASA’s Kennedy Space Center in  Florida. Centennial Challenges are part of the Prizes, Challenges, and Crowdsourcing program under NASA’s Space Technology Mission Directorate. Ensemble Consultancy supports challenge competitors. Alabama A&M University, in coordination with NASA, supports the final competitions and winner event for the challenge.

NASA’s Perseverance Fords an Ancient River to Reach Science Target

Originally thought of as little more than a route clear of rover-slowing boulders, Neretva Vallis has provided a bounty of geologic options for the science team.   

After detouring through a dune field to avoid wheel-rattling boulders, NASA’s Perseverance Mars rover reached its latest area of scientific interest on June 9. The route change not only shortened the estimated drive time to reach that area — nicknamed “Bright Angel” — by several weeks, but also gave the science team an opportunity to find exciting geologic features in an ancient river channel.

Perseverance is in the later stages of its fourth science campaign, looking for evidence of carbonate and olivine deposits in the “Margin Unit,” an area along the inside of Jezero Crater’s rim. Located at the base of the northern channel wall, Bright Angel features rocky light-toned outcrops that may represent either ancient rock exposed by river erosion or sediments that filled the channel. The team hopes to find rocks different from those in the carbonate-and-olivine-rich Margin Unit and gather more clues about Jezero’s history.

To get to Bright Angel, the rover drove on a ridge along the Neretva Vallis river channel, which billions of years ago carried a large amount of the water that flowed into Jezero Crater. “We started paralleling the channel in late January and were making pretty good progress, but then the boulders became bigger and more numerous,” said Evan Graser, Perseverance’s deputy strategic route planner lead at NASA’s Jet Propulsion Laboratory in Southern California. “What had been drives averaging over a hundred meters per Martian day went down to only tens of meters. It was frustrating.”

Channel Surfing

In rough terrain, Evan and his team use rover imagery to plan drives of about 100 feet (30 meters) at a time. To go farther on any given Martian day, or sol, planners rely on Perseverance’s auto-navigation, or AutoNav, system to take over. But as the rocks became more plentiful, AutoNav would, more times than not, determine the going was not to its liking and stop, dimming the prospects of a timely arrival at Bright Angel. The team held out hope, however, knowing they might find success cutting across a quarter-mile (400-meter) dune field in the river channel.

“We had been eyeing the river channel just to the north as we went, hoping to find a section where the dunes were small and far enough apart for a rover to pass between — because dunes have been known to eat Mars rovers,” said Graser. “Perseverance also needed an entrance ramp we could safely travel down. When the imagery showed both, we made a beeline for it.”

The Perseverance science team was also eager to travel through the ancient river channel because they wanted to investigate ancient Martian river processes.

Rock Star

With AutoNav helping guide the way on the channel floor, Perseverance covered the 656 feet (200 meters) to the first science stop in one sol. The target: “Mount Washburn,” a hill covered with intriguing boulders, some of a type never observed before on Mars.

“The diversity of textures and compositions at Mount Washburn was an exciting discovery for the team, as these rocks represent a grab bag of geologic gifts brought down from the crater rim and potentially beyond,” said Brad Garczynski of Western Washington University in Bellingham, the co-lead of the current science campaign.“But among all these different rocks, there was one that really caught our attention.” They nicknamed it “Atoko Point.”

Some 18 inches (45 centimeters) wide and 14 inches (35 centimeters) tall, the speckled, light-toned boulder stands out in a field of darker ones. Analysis by Perseverance’s SuperCam and Mastcam-Z instruments indicates that the rock is composed of the minerals pyroxene and feldspar. In terms of the size, shape, and arrangement of its mineral grains and crystals — and potentially its chemical composition — Atoko Point it is in a league of its own.

Some Perseverance scientists speculate the minerals that make up Atoko Point were produced in a subsurface body of magma that is possibly exposed now on the crater rim. Others on the team wonder if the boulder had been created far beyond the walls of Jezero and transported there by the swift Martian waters eons ago. Either way, the team believes that while Atoko is the first of its kind they’ve seen, it won’t be the last.

After leaving Mount Washburn, the rover headed 433 feet (132 meters) north to investigate the geology of “Tuff Cliff” before making the four-sol, 1,985-foot (605-meter) journey to Bright Angel. Perseverance is currently analyzing a rocky outcrop to assess whether a rock core sample should be collected.

More About the Mission

A key objective for Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.

Sols 4212-4214: Gearing up to Drill!

Earth planning date: Monday, June 11, 2024

Curiosity is gearing up to drill! Last week, it encountered a rock with unusual coloration and texture that was just out of reach (you can read about it and see pictures here and here). So that Curiosity could learn more about the geology around these rocks, it “bumped” – completing a 0.7-meter drive (2.3 feet) – to reach a nearby rock that’s big enough to drill! After many discussions over the past week with engineers, geologists, chemists, and more, the team has confirmed this target will be our next potential drill target (pictured). We’ve chosen the target name “Mammoth Lakes,” named for a town in California’s Sierra Nevada mountains with basalt columns, hot springs, and waterfalls.

Today, as the Keeper of the Plan for the Geology and Mineralogy theme group, I was busy recording all the necessary observations into the plan as we prepare to drill. In the first sol, we’ll start with some essential preparatory activities. We’ll use our Dust Removal Tool (DRT) to clean the surface, take detailed images with the Mars Hand Lens Imager (MAHLI) to capture the sedimentary textures, and analyze the composition with the Alpha Particle X-ray Spectrometer (APXS). These steps are crucial to understand the site’s potential before we commit to drilling.

The second sol is where things heat up. ChemCam will fire up its Laser Induced Breakdown Spectroscopy (LIBS) to zap the rock and analyze its makeup. We then follow up this activity with imaging the surrounding area to help us understand the context of “Mammoth Lakes.” Mastcam will devote half an hour to capture a mammoth mosaic of the area, showing a potential contact in Gediz Vallis ridge which is marked by a transition from white stones into a coarser material. To top it off, we’ll use the ChemCam’s Remote Micro-Imager (RMI) to get some high-res shots of the sedimentary textures and structures within the surrounding rocks to help us understand the depositional environment when they formed.

Even with all these activities, the environmental science theme group managed to fit in some dust monitoring. Here’s hoping all goes well, and we can make “Mammoth Lakes” our 41st drill hole!

Ames Research Center Democratizes Space Biosciences Research with First Commercial Astronaut Data

Background: To protect astronauts from spaceflight health risks like solar radiation and microgravity, scientists develop countermeasures by studying model organisms exposed to the space environment. For the first time, commercial astronaut data from the Inspiration4 (I4) mission has been collected for open-access research in an effort led by Weill Cornell Medicine. ARC’s Open Science Data Repository (OSDR) hosts this data for public use. Facilitated by the OSDR, data from the all-civilian crew enables researchers to validate decades of model organism research and make vital discoveries from biospecimens of humans. The OSDR’s Analysis Working Groups (AWGs), comprised of researchers from around the globe, collaborate to maximize the scientific value of space omics data.

Main Findings: On June 11, 44 scientific publications, including 32 authored by members of the AWG community and the OSDR team, were prominently featured in the Space Omics and Medical Atlas (SOMA) package of publications in Nature Press. The collection of articles greatly expands our knowledge of how space travel affects humans by addressing questions about the transcriptomic, epigenomic, cellular, microbiome, and mitochondrial alterations observed during spaceflight. Results and best practices from these articles collectively inform SOMA, which provides a standardized approach to spaceflight related research (Figure).

Impact: The AWG studies featured in these publications leverage the I4 data alongside other OSDR data to pioneer novel discoveries and formulate new hypotheses aimed at uncovering systemic biological responses during spaceflight. Historically, AWG collaborations have led to numerous scientific presentations at conferences, publications in high-impact journals, and the introduction of many new and more diverse researchers into the field.
