HONG KONG (PolyU PR) — With the huge amount of digital data generated and recorded during space missions, the data storage devices currently used for this purpose reveal great limitations in terms of their data storage capacity and the durability of the retained data.
To meet this challenge, a team of The Hong Kong Polytechnic University (PolyU) researchers has developed a novel technology for massive data management involving the use of peptides, which has been developed to optimise data storage for space exploration in China’s next-generation manned spacecraft in the new Long March-5B rocket.
In a statement on Friday, NASA Administrator Jim Bridenstine said the uncontrolled reentry of the core stage from the recently launched Chinese Long March 5 could have fallen on U.S. cities before reentering over the Atlantic Ocean and west Africa.
“The empty core stage of the Long March 5B, weighing nearly 20 tons, was in an uncontrolled freefall along a path that carried it over Los Angeles and other populated areas. As a matter of fact, had this spent rocket stage, which is the largest uncontrolled object to fall from low-Earth orbit in almost 30 years, reentered earlier, it could have hit New York. Two villages in Cote d’Ivoire have reported finding what they believe to be debris from the fallen rocket.
A Chinese next-generation crewed spacecraft landed on Friday after a nearly three-day automated flight in Earth orbit.
Pictures from Chinese media showed the capsule descending under three parachutes. The vehicle had made a high-speed reentry from a final orbit of 523 x 6,278 km (325 x 3,901 miles) to simulate a return from deep space.
The new spacecraft, which will carry up to six astronauts, is intended to replace the three-seat Shenzhou spaceship now in use. China will use the new vehicle for operations in Earth and lunar orbit.
A Long March 5B launched the spacecraft into Earth orbit on Tuesday from the Wenchang Satellite Launch Center on Hainan Island. It was the maiden flight of Long March 5 variant, which will be used to launch elements of China’s first permanent space station next year.
Long March 5B has a core stage with four strap-on boosters. It lacks the upper stage of the Long March 5, which is used to send communications satellites to geosynchronous orbit and probes to the moon and planets.
In a crucial step forward for China’s human and robotic spaceflight programs, a Long March 5B booster conducted its maiden flight on Tuesday carrying a prototype of the nation’s next-generation crewed spacecraft.
China’s most powerful rocket lifted off at 1000 GMT (6 p.m. local time) from the Wenchang Satellite Launch Center on Hainan Island. Chinese media have reported the launch from the nation’s southern spaceport was successful.
BEIJING, February 7, 2020 (CASC PR) — Only one month after the successful launch of the Long March 5 and Long March 3 rockets, another member of the Long March 5 rocket family, developed by China Aerospace Science and Technology Corporation (CASC), started its first journey.
