Fires Erupt in South-Central Chile 

Wildland fires broke out amid hot and dry conditions in south-central Chile in mid-January 2026, prompting evacuations and causing extensive damage to infrastructure. As of January 20, the spate of deadly fires had burned more than 30,000 hectares (74,000 acres) in the country’s Biobío and Ñuble regions, according to Chile’s National Forestry Corporation.

The MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Terra satellite captured this image of smoke billowing from multiple fires on January 18. Dozens of active fires in the area prompted the evacuation of 50,000 people and destroyed more than 300 homes, according to a January 19 report from Chile’s U.N. Resident Coordinator’s Office. Aerial and ground-based photographs showed neighborhoods in Concepción charred in the aftermath.

Gusty winds, along with temperatures that exceeded 38 degrees Celsius (100 degrees Fahrenheit) in places, fanned the flames and hampered firefighting efforts, according to news reports. Chile’s president declared a state of catastrophe in the Biobío and Ñuble regions, allowing more resources to go toward battling the blazes and assisting affected communities.

Other parts of South America also faced hot and dry conditions during the 2025–2026 summer, likely priming vegetation to burn. About 650 kilometers (400 miles) south of Concepción, firefighters in Argentina battled wildfires in and around Los Alerces National Park, home to rare stands of long-lived cypress trees.

NASA Astronaut Suni Williams Retires

After 27 years of service, NASA astronaut Suni Williams retired from the agency, effective Dec. 27, 2025. Williams completed three missions aboard the International Space Station, setting numerous human spaceflight records throughout her career.

“Suni Williams has been a trailblazer in human spaceflight, shaping the future of exploration through her leadership aboard the space station and paving the way for commercial missions to low Earth orbit,” said NASA Administrator Jared Isaacman. “Her work advancing science and technology has laid the foundation for Artemis missions to the Moon and advancing toward Mars, and her extraordinary achievements will continue to inspire generations to dream big and push the boundaries of what’s possible. Congratulations on your well-deserved retirement, and thank you for your service to NASA and our nation.”

Williams logged 608 days in space — second on the list of cumulative time in space by a NASA astronaut. She ranks sixth on the list of longest single spaceflight by an American, tied with NASA astronaut Butch Wilmore, both logging 286 days during NASA’s Boeing Starliner and SpaceX Crew-9 missions. Williams also completed nine spacewalks, totaling 62 hours and 6 minutes, ranking as the most spacewalk time by a woman and fourth-most on the all-time cumulative spacewalk duration list. She also was the first person to run a marathon in space.

“Over the course of Suni’s impressive career trajectory, she has been a pioneering leader,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “From her indelible contributions and achievements to the space station, to her groundbreaking test flight role during the Boeing Starliner mission, her exceptional dedication to the mission will inspire the future generations of explorers.”

Williams launched for the first time aboard space shuttle Discovery with STS-116 in December 2006 and returned aboard space shuttle Atlantis with the STS-117 crew. She served as a flight engineer for Expeditions 14/15 and completed a then-record-breaking four spacewalks during the mission.

In 2012, Williams launched from the Baikonur Cosmodrome in Kazakhstan for a 127-day mission as a member of Expedition 32/33. She also served as space station commander for Expedition 33. Williams performed three spacewalks during the mission to repair a leak on a station radiator and replace a component that gets power from the station’s solar arrays to its systems.

Most recently, Williams and Wilmore launched aboard the Starliner spacecraft in June 2024 as part of NASA’s Boeing Crew Flight Test mission. She and Wilmore went on to join Expedition 71/72, and Williams again took command of the space station for Expedition 72. She completed two spacewalks on the mission and returned to Earth in March 2025, as part of the agency’s SpaceX Crew-9 mission.

“Suni is incredibly sharp, and an all-around great friend and colleague,” said Scott Tingle, chief of the Astronaut Office at NASA Johnson. “She’s inspired so many people, including myself and other astronauts in the corps. We’re all going to miss her greatly and wish her nothing but the best.”

Beyond her spaceflight experience, Williams held numerous roles throughout her NASA career. In 2002, she served as a NEEMO (NASA Extreme Environments Mission Operations) crew member, spending nine days living and working in an underwater habitat. After her first flight, she served as deputy chief of NASA’s Astronaut Office. She later was the director of Operations in Star City, Russia, following her second mission to the space station. Most recently, she helped establish a helicopter training platform to prepare astronauts for future Moon landings.

The Needham, Massachusetts, native holds a bachelor’s degree in physical science from the United States Naval Academy and a master’s degree in engineering management from Florida Institute of Technology in Melbourne, Florida. A retired U.S. Navy captain, Williams is an accomplished helicopter and fixed-wing pilot, having logged more than 4,000 flight hours in 40 different aircraft.

“Anyone who knows me knows that space is my absolute favorite place to be,” said Williams. “It’s been an incredible honor to have served in the Astronaut office and have had the opportunity to fly in space three times. I had an amazing 27-year career at NASA, and that is mainly because of all the wonderful love and support I’ve received from my colleagues. The International Space Station, the people, the engineering, and the science are truly awe-inspiring and have made the next steps of exploration to the Moon and Mars possible. I hope the foundation we set has made these bold steps a little easier. I am super excited for NASA and its partner agencies as we take these next steps, and I can’t wait to watch the agency make history.”

New NASA Artemis Payloads To Study Moon’s Terrain, Radiation, History

NASA announced Tuesday the selection of three new science investigations that will strengthen humanity’s understanding and exploration of the Moon. As part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, American companies will deliver these research payloads to the lunar surface no earlier than 2028.

“With CLPS, NASA has been taking a new approach to lunar science, relying on U.S. industry innovation to travel to the surface of the Moon and enable scientific discovery,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “These selections continue this pipeline of lunar exploration, through research that will not only expand our knowledge about the Moon’s history and environment, but also inform future human safety and navigation on the Moon and beyond.”

The selected scientific payloads are:

• Emission Imager for Lunar Infrared Analysis in 3D (EMILIA-3D). The EMILIA-3D payload will create three-dimensional thermal models of the lunar terrain, using a thermal imager to measure the temperature of the landscape coupled with a stereo pair of visible-light cameras. These models will help the U.S. better image and navigate the Moon’s surface through improved understanding of the properties of the dusty lunar soil, called regolith, and what temperature measurements convey about the lunar surface. The principal investigator is Andrew Ryan at the University of Arizona.

• Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER). The LISTER instrument will measure the heat flow of the Moon’s interior by drilling beneath the lunar surface, pausing at intervals to measure temperature changes and the ability of the subsurface material to conduct heat. A previous version of LISTER flew on the Blue Ghost Mission 1 CLPS delivery to the Moon’s near side, where it took eight temperature and thermal conductivity measurements and drilled down to about three feet beneath the lunar surface. This new LISTER investigation will study the heat flow generated by the Moon itself, giving us a better understanding of its thermal history. The principal investigator is Seiichi Nagihara at Texas Tech University.
• Site-agnostic Energetic Lunar Ion and Neutron Environment (SELINE). The SELINE payload will provide new insight into the Moon’s radiation environment by studying, for the first time at the lunar surface, the radiation from both primary galactic cosmic rays and their secondary particles and how this radiation interacts with the lunar regolith. Data from SELINE will improve our understanding of the planetary processes at work on the Moon, as well as inform space weather preparation and safety for long-term human exploration of the lunar surface. The principal investigator is Drew Turner at Johns Hopkins University.

These science experiments, selected through NASA’s Payloads and Research Investigations on the Surface of the Moon call for proposals, do not require a specific landing site on the lunar surface to gather their data, and NASA will assign them to specific CLPS delivery task orders at a later time.

NASA uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon and beyond. By supporting a steady cadence of lunar deliveries, the agency will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.
