China launched a Long March 2D carrier rocket on Saturday morning to transport an experimental satellite into space, according to China Aerospace Science and Technology Corp. The State-owned space conglomerate said in a press release that the rocket blasted off at 9:01 am at the Jiuquan Satellite Launch Center in northwestern China and soon sent the Shiyan 20C, or Experiment 20C, into its preset orbit. The satellite has been designed and built by the Shanghai-based Innovation Academy for Microsatellites of the Chinese Academy of Sciences. It is tasked with demonstrating new technologies used for purposes such as space environmental monitoring. Long March 2D, made by the company's Shanghai Academy of Spaceflight Technology, is propelled by liquid propellants and has a liftoff thrust of 300 metric tons. It is capable of sending a 1.3-ton spacecraft to a sun-synchronous orbit with an altitude of 700 kilometers. The launch mission marked the 445th flight of the Long March rocket family and the country's 46th space missions this year. China plans to undertake more than 60 rocket launches in 2022.

Thermal control designs keep astronauts cool on space station Beijing (XNA) Oct 27, 2022 For astronauts, staying cool and comfortable on China's Tiangong space station is no problem. The station orbits Earth in about 90 minutes at an altitude of 400 km. It experiences large fluctuations in temperature, ranging from 150 degrees Celsius when the station is exposed to the sun to minus 100 degrees Celsius when over the night side of the planet. So how to protect station residents from extreme heat and cold during their six-month stay in orbit? The answer lies in several thermal control designs ... read more
