A NASA sensor was able to detect the exact location of a 120-acre fire burning in Alabama which had not yet been reported to officials.
The sensor—AVIRIS-3—was flying on board a research plane three miles east of Castleberry, Alabama on March 19, when the imaging spectrometer picked up the large field fire.
A scientist on board analyzed the data and was able to map out where the blaze was burning most intensely—in this case, the northeastern edge—and the information was immediately sent to emergency workers on the ground who set off to contain the fire.
The sensor picked up the blaze, which had seemingly gone unnoticed and had not yet been reported to officials, and enabled firefighters to limit the spread and save buildings in its potential path.
According to NASA, the process—from detection to alerting firefighters—took but a few minutes. The data perfectly illustrated to emergency workers the perimeter of the fire, helping them determine whether it could spread, and where personnel and equipment should go to best tackle the wildfire.
The sensor was used to map a wildfire near Castleberry, Alabama, and sent to firefighters who were able to contain the blaze.

Ethan Barrett, fire analyst for the Forest Protection Division of the Alabama Forestry Commission, explained in a statement: "Fire moves a lot faster than a bulldozer, so we have to try to get around it before it overtakes us. These maps show us the hot spots.
"When I get out of the truck, I can say, 'OK, here's the perimeter.' That puts me light-years ahead."
Robert Green, the AVIRIS program's principal investigator and senior research scientist at NASA's Jet Propulsion Laboratory, called it "very agile science"; in March alone, the team used the sensor to map at least 13 wildfires in real time.
This is a major development, as data from sensors can take days or weeks to be processed into detailed, multilayered images to be used in research. But by simplifying calibration algorithms, the data can now be processed on a computer as it is happening.

And airborne satellite internet connectivity enabled the images to be distributed, in this case to firefighters and researchers on the ground, almost immediately.
AVIRIS-3 uses three types of maps: one showing burned areas and smoke, another looking for spots burning particularly hot, including perimeters of ongoing blazes, and another to identify the intensity of the burning.

Opinion - After the Trump-Musk dustup, NASA has much to consider
The social media-driven feud between President Donald Trump and SpaceX CEO Elon Musk may have simmered down a bit, with the rhetoric cooling and Musk even deleting some of his ill-considered posts about Trump from X and then apologizing for them. But the shockwaves generated by the tit-for-tat insults and threats still reverberate through NASA and the commercial space sector. When Trump threatened to pull all of SpaceX's government contracts and Musk responded by threatening to decommission the Dragon spacecraft, an apocalyptic scenario that would have cripped NASA loomed. Fortunately, both men have since backed off. Even so, according to the Washington Post, NASA and the Defense Department are quietly urging commercial space companies to hurry the development of hardware that can compete with what SpaceX has to offer. Encouraging competition with SpaceX is sound policy regardless of the relationship between Trump and Musk. However, that competition is months, if not years, in the future. The next flight of the Boeing Starliner, which failed so spectacularly in 2024, will be early next year at the earliest. The Blue Origin New Glenn, an answer to the SpaceX Falcon family of rockets, may launch once more this year and is a long way from achieving Falcon-level launch cadence. It is in Trump's and Musk's interests, and that of the American space effort, that both men repair their relationship and move on. One of the issues that drove Trump and Musk apart was Trump's abrupt and inexplicable withdrawal of the nomination of Jared Isaacman, a billionaire entrepreneur and private space traveler, for NASA administrator. Musk had championed Isaacman, who is well regarded in the aerospace community, and took it to heart when Trump changed his mind about his own nominee. The resulting leadership vacuum at NASA is being filled by Congress. The Senate Commerce Committee, chaired by Sen. Ted Cruz (R-Texas), has offered its own ideas for a NASA budget. The Senate Commerce document is at odds with the White House proposal in one important aspect. Whereas the Trump budget eliminates the Space Launch System after Artemis III and the Lunar Gateway, Senate Commerce would retain the massive, expensive rocket at least through Artemis V and would build the Gateway to support future Artemis missions. A NASA administrator such as Isaacman would be able to argue for the White House's approach. As for Isaacman, some people in the MAGA world, no doubt stung by the near-universal outrage sparked by his treatment at the hands of the White House, have started to trash the former nominee in the media. A recent Daily Caller story quoted unnamed White House officials accusing Isaacman of not only giving money to Democrats but of supporting diversity, equity and inclusion initiatives at his companies and in his private spaceflights. But both of these facts were known when Isaacman was nominated. According to the story, the officials said, 'Isaacman would have been a black spot on an administration otherwise filled with Republican Trump supporters or, at least, individuals like Robert F. Kennedy Jr. who backed the president prior to the election.' To hear these unnamed sources talk, Isaacman is no better than left-wing House members Rep. Alexandria Ocasio-Cortez (D-N.Y.), Rep. Ilhan Omar (D-Minn.) and their Squad. It should be noted that even if Isaacman wanted to impose DEI policies at NASA, he couldn't because of Trump's executive order prohibiting it across the federal government. Isaacman posted to X in his own defense: 'I am a moderate and donated to both parties for different reasons … my largest contribution was to President Trump — because I support many of his policies. I definitely did not like the direction this country was going over the last 4 years.' He went on to state, 'I have never spoken against the President. I have never voted against him.' It sounds like Isaacman is very loyal to Trump, remarkable under the circumstances. The suggestion of disloyalty is spurious and against the White House's interests. Isaacman's situation could provide the basis of a rapprochement between Trump and Musk. Musk has already apologized to the president for some of his posts on X, particularly the one suggesting that Trump is named in the Department of Justice's files on Jeffrey Epstein. But the president should admit fault as well. He was deceived by some of his staff about Isaacman's character. If it is not too late, he should reverse himself a second time and send his fellow billionaire's name back into nomination. NASA, the U.S., and the Trump-Musk partnership would gain as a result.

Astronaut's sublime Earth photo is surely one of his best yet
NASA astronaut Don Pettit has been back on terra firma for almost two months and he's still able to dig out some awesome photos that he took during his half-a-year stay on the International Space Station (ISS). Pettit's latest image, posted for the first time on X on Sunday, shows the lights of cities and fishing fleets across southeast Asia, an atmospheric glow, the Milky Way, and part of the station itself as it orbited Earth 250 miles up. The city lights of Southeast Asia beneath the Milky Way. Vibrant colors of LED cities, orange atmospheric airglow, and fishing fleets are blurred by my sidereal drive, while tracking stars as fixed points in space. — Don Pettit (@astro_Pettit) June 16, 2025 The dramatic blur is caused by the extended exposure time and the motion of the orbital outpost, which is traveling through space at a speed of about 17,500 mph. The distant stars, however, remain sharp due to the use of a sidereal drive, a device that works by moving the camera at the same speed as the stars appear to move, thereby eliminating their movement within the frame. Recommended Videos During his recent stint aboard the space station, Pettit dazzled his many follows on X and Instagram with impressive photos and video of Earth and beyond. Check out this page where you can find some of his best work. Pettit has spoken previously about how the cameras are set up on the ISS to give astronauts the best chance of capturing an image when something catches their eye. 'Generally speaking, we don't turn any of the cameras off,' he told Time magazine. 'We don't put lens caps on. The cameras that are staged next to the window [of the cupola] are just set up, ready to go. 'And we'll have one camera with a 200 millimeter telephoto lens, and another camera with a 14 millimeter wide angle lens, and we'll have three or four cameras set up in between, because when you're taking pictures you don't have time to change lenses. So you just grab one camera, go click click click, set it down, grab another camera, click click click, grab another camera, click click click. And there's your 10-second window to get a picture of your hometown or the Pyramids.' Now aged 70, it's not yet clear if NASA's oldest serving astronaut will return to orbit, but happily for his fans, it seems that he's still got plenty of new content that he's eager to share.

135-Year-Old Tortoise Celebrates First Father's Day
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Goliath, a 517-pound Galapagos tortoise and the oldest animal at Zoo Miami, celebrated his 135th birthday and became a father for the first time, zoo officials announced in a post on Facebook. Zoo Miami officials said they submitted an application to Guinness World Records to recognize Goliath as the world's "Oldest First-Time Father," and for Goliath and Sweet Pea as the "Oldest First-Time Parents." Their combined ages total more than 200 years. "Not only is this the first offspring for Goliath, but it is also the first time in the history of Zoo Miami that a Galapagos tortoise has hatched, making this an historic event on multiple levels!" the post read. Why It Matters The Galapagos tortoise is listed as endangered, with population numbers once drastically reduced by direct exploitation and habitat disruption. Modern threats of climate change and ongoing habitat loss contribute to conservation urgency. Found natively in Ecuador's Galapagos Islands, wild populations of the tortoise have suffered sharp declines because of human exploitation and invasive species introduction. The successful breeding of the species at Zoo Miami represents a significant win for conservation efforts in the United States. Hatchling from one egg out of a clutch of 8 that was laid January 27th, successfully hatched on June 4th, 2025. Hatchling from one egg out of a clutch of 8 that was laid January 27th, successfully hatched on June 4th, 2025. Zoo Miami What To Know Goliath, who hatched on Santa Cruz Island in the Galapagos sometime between 1885 and 1890 according to varying official records, has resided in the U.S. since 1929 and at Zoo Miami since 1981. Although he has bred with several females, this is his first confirmed offspring in at least four decades of attempts, according to Zoo Miami. The hatchling was born on June 4, 2025 after 128 days of incubation - the first of its species to be bred and hatched at the South Florida zoo, marking a milestone moment for conservation and the institution's history, according to the post. The clutch, laid by Goliath's companion Sweet Pea on January 27, originally contained eight eggs but only one egg hatched successfully. On this Father's Day, Zoo Miami's oldest animal will be celebrating his 134th birthday! His name is 'Goliath,' and he is a Galapagos tortoise that weighs 517 pounds! Up until this prior week, he had... Sweet Pea is between 85 and 100 years old and has lived at Zoo Miami since 1960. The parents live in a public habitat, while the energetic hatchling is monitored in a protected enclosure, the Zoo explained. The oldest living tortoise known is Jonathan, a Seychelles giant tortoise living on St. Helena and estimated to be 191 years old, as noted by the Guinness Book of World Records. What People Are Saying Zoo Miami said in a post on Facebook: "Goliath is my hero, and I am sure he will soon be an inspiration to many others! He is living proof that where there is a will, there is a way and to never give up!" What Happens Next The hatchling will remain under care in a specially monitored enclosure at Zoo Miami. Meanwhile, the application for Goliath's potential world record is under review by Guinness World Records. Zoo officials will continue their breeding and conservation programs with a focus on sustaining endangered reptilian species.
