NASA, IBM team up to develop AI-based models to spur new Earth discoveries

NASA and IBM have collaborated to develop artificial intelligence (AI) based models that will make it easier to mine vast datasets to advance scientific knowledge about Earth, and help the world to adapt to a changing environment. The joint work will apply AI foundation model technology to NASA's Earth-observing satellite data for the first time, NASA said in a statement. Foundation models are types of AI models that are trained on a broad set of unlabelled data, can be used for different tasks, and can apply information about one situation to another. "The beauty of foundation models is they can potentially be used for many downstream applications," said Rahul Ramachandran, a senior research scientist at NASA's Marshall Space Flight Center. "Building these foundation models cannot be tackled by small teams; you need teams across different organisations to bring their different perspectives, resources, and skill sets," Ramachandran said in a statement. One project will train an IB

2022 fifth warmest year on record; trend alarming, says NASA analysis

Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by (NASA). Continuing the planet's long-term warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit, or 0.89 degrees Celsius, above the average for NASA's baseline period 1951-1980, scientists from NASA's Goddard Institute for Space Studies (GISS) in New York reported. "This warming trend is alarming," said NASA Administrator Bill Nelson. "Our warming climate is already making a mark: Forest fires are intensifying; hurricanes are getting stronger; droughts are wreaking havoc and sea levels are rising. NASA is deepening our commitment to do our part in addressing climate change," said Nelson. The past nine years have been the warmest years since modern recordkeeping began in 1880. This meant Earth in 2022 was about 2 degrees Fahrenheit, or about 1.11 degrees Celsius, warmer than the late 19th century average, the study said. "The reason for the warming

40 year-old NASA science satellite falls harmlessly from sky off Alaska

After almost 40 years circling Earth, a retired NASA science satellite plunged harmlessly through the atmosphere off the coast of Alaska, NASA reported Monday. The Defense Department confirmed that the satellite - placed in orbit in 1984 by astronaut Sally Ride - reentered late Sunday night over the Bering Sea, a few hundred miles from Alaska. NASA said it's received no reports of injury or damage from falling debris. Late last week, NASA said it expected most of the 5,400-pound (2,450-kilogram) Earth Radiation Budget Satellite to burn up in the atmosphere, but that some pieces might survive. The space agency put the odds of falling debris injuring someone at 1-in-9,400. Space shuttle Challenger carried the satellite into orbit and the first American woman in space set it free. The satellite measured ozone in the atmosphere and studied how Earth absorbed and radiated energy from the sun, before being retired in 2005, well beyond its expected working lifetime.

38-yr-old retired Nasa satellite to fall from sky this weekend, low threat

A 38-year-old retired NASA satellite is about to fall from the sky. NASA said Friday the chance of wreckage falling on anybody is very low. Most of the 5,400-pound (2,450-kilogram) satellite will burn up upon reentry, according to NASA. But some pieces are expected to survive. The space agency put the odds of injury from falling debris at about 1-in-9,400. The science satellite is expected to come down Sunday night, give or take 17 hours, according to the Defense Department. The California-based Aerospace Corp., however is targeting Monday morning, give or take 13 hours, along a track passing over Africa, Asia the Middle East and the westernmost areas of North and South America. The Earth Radiation Budget Satellite, known as ERBS, was launched in 1984 aboard space shuttle Challenger. Although its expected working lifetime was two years, the satellite kept making ozone and other atmospheric measurements until its retirement in 2005. The satellite studied how Earth absorbed and radi

Nasa's Orion capsule returns from moon, lands in Pacific Ocean off Mexico

NASA's Orion capsule made a blisteringly fast return from the moon Sunday, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby. The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) before splashing down west of Mexico's Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants three test dummies rigged with vibration sensors and radiation monitors. NASA needed a successful splashdown to stay on track for the next Orion flight around the moon, currently targeted for 2024. Four astronauts will make the trip. That will be followed by a two-person lunar landing as early as 2025. Astronauts last landed on the moon 50 years ago Sunday. After touching down on Dec. 11, 1972, Apollo 17's Eugene Cernan and Harrison Schmitt spent three da

Nasa's Orion capsule flies over Apollo landing sites, heads home

NASA's Orion capsule and its test dummies swooped one last time around the moon Monday, flying over a couple Apollo landing sites before heading home. Orion will aim for a Pacific splashdown Sunday off San Diego, setting the stage for astronauts on the next flight in a couple years. The capsule passed within 130 kilometres of the far side of the moon, using the lunar gravity as a slingshot for the 3,80,000-kilometre ride back to Earth. It spent a week in a wide, sweeping lunar orbit. Once emerging from behind the moon and regaining communication with flight controllers in Houston, Orion beamed back photos of a close-up moon and a crescent Earth Earthrise in the distance. Orion now has its sights set on home," said Mission Control commentator Sandra Jones. The capsule also passed over the landing sites of Apollo 12 and 14. But at 1,900 kilometres up, it was too high to make out the descent stages of the lunar landers or anything else left behind by astronauts more than a half-cen
