This star was spun up by accreting the materials from its expanding companion in the binary system, and then kicked off when the supernova explosion happened at the end of the companion's life, Li said. He also found that this star, located about 30,000 light years away from the sun, is moving away from its birthplace at a speed of 120 km per second, which implies that it probably originates from a binary system. It has an oblate shape because of the extremely rotational speed, with its equatorial radius longer than the polar radius, which results in higher gravities at poles and lower gravity around the equator, said Li, adding that the temperatures at the two poles are higher than that of equator. The star, named LAMOST J040643.69+542347.8, has an estimated rotational velocity of 540 km per second, which is about 100 km per second faster than that of the previous record holder, HD 191423.īy analyzing the spectrum of this star, Li Guangwei, an associate researcher of the National Astronomical Observatories of the Chinese Academic of Sciences, found that it is a massive star with a high temperature.

New version of Long March to make its debut - Ĭhinese astronomer discovers fastest rotating star in Milky Way It will also be able to bring items back to Earth from the space station, Yang said, adding that its re-entry module will be reusable. Yang Qing, chief structural designer of the spacecraft, said: "This coming mission will serve to examine and demonstrate the new spaceship's re-entry, heat-resistance and recovery technologies and will lay a solid foundation for the improvement of the spaceship's design."Ĭompared with the Shenzhou series, the country's operational crewed spacecraft family, the new generation of manned spaceship will be capable of conducting longer missions and operating in a hotter environment, he noted.įurthermore, it will be able to carry three astronauts and as much as 500 kilograms of cargo into space. It will be tasked with serving the construction and operation of China's future space station as well as the country's manned lunar missions being planned by scientists, the agency noted. The China Manned Space Agency said the new-generation manned spaceship has a total length of 8.8 meters and a liftoff weight of 21.6 tons. Li Dong, the rocket's chief designer, said that the craft will be pollution-free and will be the most powerful rocket when it comes to carrying capacity to low-Earth orbit, capable of placing 22 tons of payload into such orbit.
It will be propelled by liquid oxygen, liquid hydrogen and kerosene and will have a liftoff weight of about 849 metric tons. The new model will be tasked with sending large spacecraft to low-Earth orbit, the academy said in a statement.Ī Long March 5B is 53.7 meters long, with a diameter of 5 meters.
The rocket was transported to the launch center in February by two rocket transportation ships－Yuanwang 21 and Yuanwang 22-from Tianjin, a northern coastal municipality that is home to the rocket's manufacturing complexes, and has been undergoing tests and prelaunch preparations since then.Īccording to the China Academy of Launch Vehicle Technology in Beijing, the leading rocket developer in the country, Long March 5B is the first variant of the Long March 5, which conducted its third mission at the Wenchang center in December. The coming flight will send the first prototype of the country's new manned spaceship into orbit to verify that the design of the rocket and the spacecraft are suitable, the agency said. The agency recently published a picture of the first Long March 5B that has been assembled inside a colossal building, indicating the giant rocket is ready for the maiden mission.
Latest variant of rocket will be tasked with sending large craft to low orbitĬhina's Long March 5B carrier rocket is scheduled to make its debut flight later this month at the Wenchang Space Launch Center in Hainan province, according to the China Manned Space Agency.
