Beyond the risk of debris colliding with working satellites that are vital for navigation, communication and weather forecasting, large pieces could come crashing back down to Earth. /news/2025-07-paper-planes-sustainable-solutions-space.html Space Exploration Mon, 14 Jul 2025 11:30:02 EDT news671711084 Sarcopenia, which is a progressive and extensive decline in muscle mass and strength, is common with aging and is estimated to affect up to 50% of people aged 80 and older. It can lead to disability and injuries from falls and is associated with a lower quality of life and increased mortality. Apart from lifestyle changes, there is no current clinical treatment for sarcopenia. /news/2025-06-space-grown-muscle-tissues-reveal.html Space Exploration Thu, 26 Jun 2025 11:00:01 EDT news670137910 As NASA prepares to send astronauts back to the moon for the first time in over 50 years, new research from the University of Technology, Sydney (UTS) has found that lunar dust is less harmful to human lung cells than previously feared, and significantly less toxic than common Earth-based air pollution. /news/2025-06-abrasive-lunar-toxic-city-pollution.html Space Exploration Tue, 17 Jun 2025 10:15:31 EDT news669374127 An instrument built at NASA's Jet Propulsion Laboratory to map minerals on Earth is now revealing clues about water quality.

During periods of low solar activity, such as the solar minimum, more GCRs have been observed to reach Earth compared to that for periods of high solar activity. This inverse correlation between the GCR-flux and solar activity is known as "solar modulation." /news/2023-06-calorimetric-electron-telescope-calet-captures.html Astronomy Thu, 08 Jun 2023 16:11:03 EDT news605459461 China launched a new three-person crew for its orbiting space station on Tuesday, with an eye to putting astronauts on the moon before the end of the decade. /news/2023-05-china-crew-space-station-eye.html Space Exploration Tue, 30 May 2023 04:03:42 EDT news604638214 China's burgeoning space program plans to place astronauts on the moon before 2030 and expand the country's orbiting space station, officials said Monday. /news/2023-05-china-astronauts-moon-space.html Space Exploration Mon, 29 May 2023 04:44:16 EDT news604554250 Much of our understanding of the universe and its mysterious phenomena is based on theoretical interpretations.
