The tectonic plates that form the Earth's surface are like puzzle pieces that are in constant, very slow motion - on average, they move only up to around 10 centimeters a year. But these puzzle pieces don't quite fit together: there are zones on one plate that end up plunging under another - the so-called subduction zones, central to the dynamics of the planet.

China will carry on its moon research in the future with Chang'e-6, Chang'e-7 and Chang'e-8 missions by 2030, chief designer of the country's lunar exploration program Wu Weiren said.
The Chang'e-6 is scheduled to bring back to Earth lunar samples with a mass of up to 2 kilograms; the Chang'e-7 will be tasked with landing on the lunar south pole and detecting local natural resources; and t

Over the past two decades, the Arctic has lost about one-third of its winter sea ice volume, largely due to a decline in sea ice that persists over several years, called multiyear ice, according to a new study. The study also found sea ice is likely thinner than previous estimates.

Russia's annexation of Crimea in 2014 meant Ukraine lost access to a major satellite ground station located there. That annexation, and ongoing unrest in eastern Ukraine, have also cut off most business Ukraine's space industry had with Russia.

Ukraine's space agency, and the country's small but highly specialized space industry, have been hit harder than Russia by the conflict over Crimea. The real problem was the political impact on Ukraine's industrial ties with Russia, the main customer for the two flagship enterprises of Ukraine's space industry.
