The Parker Solar Probe spacecraft, NASA's newest and most ambitious effort to study the sun, has broken a lot of records: it has gotten closer to the sun than any other spacecraft to date, its instruments have operated at the hottest temperatures, and the probe is the fastest human-made object ever. But those records come at a cost: The spacecraft is moving so fast that running into even a tiny

China launched its Shijian 21 satellite into orbit from Xichang late in October on a mission to "test and verify space debris mitigation technologies". However, the launch triggered fears in the US military that Beijing had unveiled a new "satellite-crushing" weapon to achieve superior space attack systems.

NASA has selected a new Earth science mission that will study the behavior of tropical storms and thunderstorms, including their impacts on weather and climate models. The mission will be a collection of three SmallSats, flying in tight coordination, called Investigation of Convective Updrafts (INCUS), and is expected to launch in 2027 as part of NASA's Earth Venture Program.

Radiocarbon records are critical to understanding the history of Earth's climate, magnetic field, and the Sun's activity, say researchers.
In an article published in the journal Science, scientists have highlighted how recent advances in our knowledge of past radiocarbon levels are improving our understanding of climate processes, solar activity, geophysics and the carbon cycle.

Much of the critical data used to track climate change and its impact on Earth is collected by satellites in space. But all that data needs to be better analyzed in order to better cope with the climate crisis, said Ellen Stofan, undersecretary for science and research at the Smithsonian Institution.
