China Leverages Space Tech to Meet Climate Goals

China sent a greenhouse gas monitoring payload to the Chinese space station by the Tianzhou-10 cargo spacecraft on May 11. The device can measure carbon dioxide and methane concentrations at key emission sources across the globe's mid-to-low latitudes. This will provide reliable, accurate, and high-frequency data to support greenhouse gas monitoring, reporting and verification.

Chang'e-6 Samples Reveal Asteroid Bombardment Secrets

Chinese scientists studying Chang'e-6 lunar samples have discovered a major shift in asteroid impacts on the Earth-moon system 4.3-2.8 billion years ago, from non-carbonaceous to carbonaceous asteroid dominance.

New Mars Helicopter Exceeds Speed of Sound

NASA's next-generation Mars helicopters have broken the sound barrier. During recent tests, the rotor blades for the upcoming SkyFall mission (to send next-generation helicopters to Mars) reached the speed of Mach 1.08 in a simulated Martian atmosphere.

Antarctic Sea Ice Decline May Accelerate Global Warming

A cascade of ocean and atmospheric changes has driven a rapid decline in Antarctic sea ice since 2015, which could accelerate global warming, new research has revealed. The study found a "triple whammy" of interacting climate processes tipped the Southern Ocean into a new state, according to a statement from Australia's University of New South Wales released on Monday.
