BEIJING - China has successfully tested its new space program's reentry and descent technology, which makes landing heavier spacecraft possible.Current spacecraft landing methods such as parachute and airbag landings can not satisfy the deceleration needs of heavier manned spacecraft reentry missions, according to China Aerospace Science and Technology Corporation (CASC).The CASC successfully conducted three experiments, involving upgraded parachute and airbag landing techniques as well as the inflatable reentry and descent technology (IRDT).It published the test results on its website earlier this week.The upgraded parachutes proved reliable with strong structure and performance and can be used to slow down a spacecraft at the initial stage of reentry.According to the test results, the upgraded airbag landing technology uses high-impact materials to cover spacecrafts during landing and can increase the current deceleration capacity.IRDT is a brand new integrated inflatable heat insulating deceleration system that CASC has deployed in experiments.Future recoverable capsules based on IRDT technology can land spacecraft without heat shields and parachutes.IRDT-based recoverable capsules will be able to provide buffer and protection to spacecraft when landing while inflating air bags which cover the spacecraft.The technology will be used in deep space exploration and the quick return of space stations, scientific experiment satellites and space freight, said the CASC. custom logo wristbandsclear silicone wristbandscustom friendship braceletscustom wrist sweatbandscheap plastic bracelets
The national security authority in Beijing received nearly 5,000 tips about possible espionage over the past year from members of the public, Beijing Daily reported on Tuesday.The newspaper quoted the Beijing Municipal Bureau of National Security as saying that the reports were made by Chinese citizens and others living overseas via the bureau's hotline 12339 after cash rewards for tips were offered a year ago. Anyone who offers clues that play an important role in the prevention of espionage or the cracking of a spy case will be rewarded up to 500,000 yuan ($79,000). The hotline was set up in 2015.The bureau said the reports have aided the crackdown on espionage, noting that through the hotline and other national security awareness campaigns, residents in Beijing have become more active in assisting national security authorities.The statement used the example of a report by a Chinese national whom a spy had tried to recruit. A doctoral student identified as Li had been approached by a man known as Peter at an academic workshop. Peter told Li that he was a researcher at an international institute. The two kept in touch after the workshop and discussed academic issues via email. In addition, Peter sent Li some academic papers and small gifts.Their contacts ended when Peter offered to help Li apply for permanent residency in the United States in exchange for Li giving him information about a classified program.The Beijing national security bureau identified Peter as a member of an overseas intelligence agency and rewarded Li for reporting the recruiting attempt. custom silicone wristbandscustom made paracord braceletsnike silicone wristbandssilicone medical alert bracelet diabetesrheumatoid arthritis silicone bracelets<%2fcenter>
