SpaceX launches four astronauts from US, Russia, and UAE to space station

SpaceX launched four astronauts to the International Space Station for NASA on Thursday, including the first person from the Arab world going up for an extended monthslong stay. The Falcon rocket bolted from Kennedy Space Center shortly after midnight, illuminating the night sky as it headed up the East Coast.. Nearly 80 spectators from the United Arab Emirates watched from the launch site as astronaut Sultan al-Neyadi only the second Emirati to fly to space blasted off on his six-month mission. Half a world away in Dubai and elsewhere across the UAE, schools and offices planned to broadcast the launch live. Also riding the Dragon capsule that's due at the space station on Friday: NASA's Stephen Bowen, a retired Navy submariner who logged three space shuttle flights, and Warren Woody Hoburg, a former research scientist at Massachusetts Institute of Technology and space newbie, and Andrei Fedyaev, a space rookie who's retired from the Russian Air Force. The first attempt to launc

Russia launches rescue ship for two cosmonauts to space station after leaks

Russia launched a rescue ship on Friday for two cosmonauts and a NASA astronaut whose original ride home sprang a dangerous leak while parked at the International Space Station. The new, empty Soyuz capsule should arrive at the orbiting lab on Sunday. The capsule leak in December was blamed on a micrometeorite that punctured an external radiator, draining it of coolant. The same thing appeared to happen again earlier this month, this time on a docked Russian cargo ship. Camera views showed a small hole in each spacecraft. The Russian Space Agency delayed the launch of the replacement Soyuz, looking for any manufacturing defects. No issues were found, and the agency proceeded with Friday's predawn launch from Kazakhstan of the capsule with bundles of supplies strapped into the three seats. Given the urgent need for this capsule, two top NASA officials travelled from the US to observe the launch in person. To everyone's relief, the capsule safely reached orbit nine minutes after lift

ISRO-NASA built satellite ready to be shipped to India for launch in Sept

An earth-observation satellite jointly developed by NASA and ISRO that will help study Earth's land and ice surfaces in greater detail is all set to be shipped to India later this month for a possible launch in September. ISRO Chairman S Somanath visited NASA's Jet Propulsion Laboratory (JPL) in the US state of California on Friday to oversee the final electrical testing of the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite before being shipped to India. This mission will be a powerful demonstration of the capability of radar as a science tool and help us study Earth's dynamic land and ice surfaces in greater detail than ever before, Somanath said at the formal send-off ceremony organised at the JPL which was attended by senior scientists from the two space agencies. Later this month, the SUV-size payload will be moved into a special cargo container for a 14,000-kilometer flight to the U R Rao Satellite Centre in Bengaluru. ISRO and NASA joined hands in 2014 to build the 2,80

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
