In this week's Science Saturday, we look at the latest science news, ranging from space missions to climate change. 

China space mission

Taikonauts grow rice seedlings in space. The experiment was conducted on Wentian, the first lab module that docked with China's space station in late July. If successful, the taikonauts will collect the seeds and bring them back to Earth for further studies. Experts say the experiment will help astronauts cultivate food for long-term space missions. There are seven other experiments onboard the lab, which are operating well. The astronauts also took part in a spacewalk on Thursday. 

NASA Moon mission

NASA aims to go back to the moon, almost 50 years after the last Apollo mission. The first mission, dubbed as Artemis-I, includes a Space Launch System (SLS) and an Orion crew capsule, The uncrewed mission will ensure that all components are working, to enable future deep space exploration. The plan is to allow humans to make the journey in the next two years. NASA hopes this mission will help it to establish a sustained presence on the moon and enable human exploration of Mars in the future. 

Social media clean-up

Two tech giants remove profiles that spread pro-US propaganda abroad. Twitter and Meta have removed dozens of accounts used in the campaign in the last two months. The targets were the Middle East and Central Asia. Researchers say the accounts promoted narratives that support the US and its allies, and opposed countries like Russia, China and Iran. It's not clear who's behind the propaganda operation, though the US and UK have been named as possible countries of origin. 

Climate change

Global sea levels are set to rise further by 27 centimeters! This is more than twice as much sea level rise as scientists had expected. The Greenland's zombie ice is the cause of this unavoidable incident. Experts say the dead ice will melt, no matter what happens with future carbon pollution. If the prediction is true, destructive floods will be at least five times as often in the U.S., and low-lying island nations and developing countries will be hardest hit.
