      NASA logo Chile will sign the Artemis Accords during a ceremony at 3 p.m. EDT on Friday, Oct. 25, at NASA’s Headquarters in Washington.
      NASA Administrator Bill Nelson will host Aisén Etcheverry, Chile’s minister of science, technology, knowledge and innovation, and Juan Gabriel Valdés, ambassador of Chile to the United States, along with other officials from Chile and the U.S. Department of State.
      This event is in-person only. U.S. media and U.S. citizens representing international media organizations interested in attending must RSVP no later than 5 p.m. on Thursday, Oct. 24, to hq-media@mail.nasa.gov. NASA’s media accreditation policy is online.
      The signing ceremony will take place at the agency’s Glennan Assembly Room inside NASA Headquarters located at 300 E St. SW Washington.
      NASA, in coordination with the U.S. Department of State and seven other initial signatory nations, established the Artemis Accords in 2020. With many countries and private companies conducting missions and operations around the Moon, the Artemis Accords provide a common set of principles to enhance the governance of the civil exploration and use of outer space.
      The Artemis Accords reinforce the commitment by signatory nations to the Outer Space Treaty, the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior for civil space exploration and use.

      Microgravity had no immediate effect on a person’s ability to perceive the height of an object, indicating that astronauts can safely perform tasks that rely on accurate and precise height judgments soon after arrival in space.

      We use the height and width of objects around us to complete tasks such as reaching for objects and deciding whether we can fit through an opening. VECTION, an investigation from the Canadian Space Agency, examined the effect of microgravity on an astronaut’s visual perception and how that ability may adapt during flight or upon return to Earth. Researchers conclude there is no need for countermeasures but suggest that space travelers be made aware of late-emerging and potentially long-lasting changes in the ability to perceive object height.
      Canadian Space Agency astronaut David Saint-Jacques conducts a session for the VECTION experiment. NASA/Anne McClain Analysis of the genomes of five new species of bacteria found on the International Space Station identified specific adaptations to space, including the development of increased antibiotic resistance and a greater potential for causing diseases. The genes that facilitate these adaptations could serve as potential targets for drugs, helping to protect crew health on future missions.

      Microbial Tracking-2 monitored viruses, bacteria, and fungi on the space station to catalog and characterize any with the potential to cause disease. Understanding the mechanisms behind adaptations to space could advance development of ways to protect crew member health as well as spacecraft and equipment on future missions. Microbial adaptations also have potential applications in biotechnology, such as engineering more resilient organisms for use in space and extraterrestrial environments.

NASA/Jack Fischer When NASA’s Airborne Lightning Observatory for Fly’s Eye and the space station’s ASIM instrument briefly passed over the same geographic area, the airborne instrument detected terrestrial gamma‐ray flashes (TGFs) that were not detected by ASIM. TGFs are short bursts of gamma‐rays produced by lightning in thunderclouds. This result suggests that a significant number of TGFs are too weak to be observed from space and that the percentage of lightning associated with these phenomena may be higher than previously thought.

      ASIM, an investigation from the European Space Agency, studies high-altitude lightning in thunderstorms and the role it plays in Earth’s atmosphere and climate. Results could help scientists develop better atmospheric models to guide weather and climate prediction and response. The airborne instrument took measurements at an altitude of about 12 miles and ASIM at approximately 260 miles above Earth’s surface.

      Just Keep Roving
      Image from Perseverance’s Right Navigation Camera, looking back towards rover tracks from past drives, into Jezero crater. The camera is located high on the rover mast, and here the rover is looking back in the direction of the Jezero crater floor. This image was acquired on October 4th, 2024 (Sol 1288) at the local mean solar time of 12:51:26. NASA/JPL-Caltech Throughout the past week, Perseverancehas continued marching up the Jezero crater rim. This steep ascent through the Martian regolith (soil) can prove to be slow driving for the rover, as the wheels can slip on the steepest areas. This is like trying to run up a hill of sand on a beach – with every step forward, you also slip back a little way down the hill! This just means the Science and Engineering teams work together closely to plan slow and steady drives through this tricky terrain.
      Driving through the Mount Ranier quadrangle, the team identified a relatively obstacle-free path to reach the crater rim which they designated Summerland Trail, aptly named from a very popular hiking trail that ascends Mount Ranier. Perseverance is trekking to the next waypoint near an outcrop of rocks called Pico Turquino, where the science team hopes to perform its next proximity science investigations with its instruments PIXL and back-online SHERLOC.
      While roving along Summerland Trail, Perseverance is constantly observing the surrounding terrain. SuperCam and Mastcam-Z have been observing rocks on the ground and on a distant hill, called Crystal Creek. In addition, during this time Perseverance can put its eyes to the sky to make observations of the sun and atmosphere. Last week, the Mastcam-Z camera captured images of Phobos (one of Mars’ two moons) transiting in front of the sun!
      This image, showing Phobos transiting in front of the sun, was acquired using Perseverance’s Left Mastcam-Z camera. Acquired on September 30th, 2024 (Sol 1285) at the local mean solar time of 11:10:04. NASA/JPL-Caltech/ASU While the Mars2020 team is itching to reach the ancient stratigraphy exposed in the crater rim, for now, the focus is on documenting our surroundings while navigating the ascent.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Jacquelyn Shuman visually assesses a prescribed fire at Ft. Stewart in Georgia, working with partner organizations as part of the Department of Defense Ft. Stewart 2024 Fire Research Campaign. USFS/Linda Chappell Jacquelyn Shuman, FireSense Project Scientist at NASA Ames Research Center, originally wanted to be a veterinarian. By the time she got to college, Shuman had switched interests to biology, which became a job teaching middle and high school science. Teaching pivoted to finance for a year, before Shuman returned to the science world to pursue a PhD.

      It was in a forest ecology class taught by her future PhD advisor, Herman “Hank” Shugart, that she first discovered a passion for ecosystems and dynamic vegetation that led her into the world of fire science, and eventually to NASA Ames.

      While Shuman’s path into the world of fire science was not a direct one, she views her diverse experiences as the key to finding a fulfilling career. “Do a lot of different things and try a lot of different things, and if one thing isn’t connecting with you, then do something different,” Shuman said.

      Diving into the World of Fire

      Shuman’s PhD program focused on boreal forest dynamics across Russia, examining how the forest changes in response to climate change and wildfire. During her research, she worked mainly with scientists from Russia, Canada, and the US through the Northern Eurasia Earth Science Partnership Initiative (NEESPI), where Shugart served as the NEESPI Chief Scientist. “The experience of having a highly supportive mentor, being a part of the NEESPI community, and working alongside other inspiring female scientists from across the globe helped me to stay motivated within my own research,” Shuman said.

      After completing her PhD, Shuman wanted to become involved in collaborative science with a global impact, which led her to the National Center for Atmospheric Research (NCAR). There, she spent seven years working as a project scientist on the Next Generation Ecosystem Experiment NGEE-Tropics) on a dynamic vegetation model project called FATES (Functionally Assembled Terrestrial Ecosystem Simulator). As part of the FATES team, Shuman used computer modeling to test vegetation structure and function in tropical and boreal forests after wildfires, and was the lead developer for updating the fire portion of the model.

      This figure shows fire characteristics from an Earth system model that uses vegetation structure and interactive fire. The FATES model captures the fire intensity associated with burned land and grass growth in the Southern Hemisphere. Shuman et al. 2024 GMD Fire has also played a powerful role in Shuman’s personal life. In 2021, the Marshall Fire destroyed neighborhoods near her hometown of Boulder, Colorado, causing over $513 million of damage and securing its place as the state’s most destructive wildfire. Despite this, Shuman is determined to not live in fear. “Fire is part of our lives, it’s a part of the Earth system, and it’s something we can plan for. We can live more sustainably with fires.” The way to live safely in a fire-inclusive ecosystem, according to Shuman, is to develop ways to accurately track and forecast wildfires and smoke, and to respond to them efficiently: efforts the fire community is continuously working on improving.

      The Fire Science Community

      Collaboration is a critical element of wildland fire management. Fire science is a field that involves practitioners such as firefighters and land managers, but also researchers such as modelers and forecasters; the most effective efforts, according to Shuman, come when this community works together. “People in fire science might be out in the field and carrying a drip torch and marching along in the hilltops and the grasslands or be behind a computer and analyzing remote sensing data,” Shuman said. “We need both pieces.”

      Protecting communities from wildfire impacts is one of the most fulfilling aspects of Shuman’s career, and a goal that unites this community. “Fire research poses tough questions, but the people who are thinking about this are the people who are acting on it,” Shuman said. “They are saying, ‘What can we do? How can we think about this? What information do we need? What are the questions?’ It’s a special community to be a part of.”

      Looking to the Future of Fire

      Currently at NASA Ames Research Center, Shuman is the Project Scientist for FireSense: a project focused on delivering NASA science and technology to practitioners and operational agencies. Shuman acts as the lead for the project office, identifying and implementing tools and strategies. Shuman still does ecosystem modeling work, including implementing vegetation models that forecast the impact of fire, but also spends time traveling to active fires across the country so she can help partners implement NASA tools and strategies in real time.

      “Right now, many different communities are all recognizing that we can partner to identify the best path forward,” Shuman said. “We have an opportunity to use everyone’s strengths and unique perspectives. It can be a devastating thing for a community and an ecosystem when a fire happens. Everyone is interested in using all this collective knowledge to do more, together.”
