Chinese authorities announced its first successful landing of a Chinese Space Plane on September 6, 2020.[1][2] The space vehicle was launched, from Juiquan, on September 4, 2020, on a Long March 2F rocket.[3][4] Reuters reported that China had first announced plans to launch a reusable spaceplane by 2020, in 2017.

Operations

First flight

On September 7, 2020, commercial satellite reconnaissance company Planet Labs published a satellite photo of a 3.1  mi (4.99  km) runway at a secretive air base in Lop Nur, taken shortly after the landing of the spaceplane.[5] Jonathon McDowell, of the Harvard-Smithsonian Center for Astrophysics, speculated that one of the dots visible on the runway is the Chinese spaceplane. He said that US had tracked the spaceplane. He speculated that the spaceplane was more likely to be similar to the United States Air Force's X-37B than NASA space shuttles.[1]

On September 8, 2020, Space Flight Now reported American officials had detected the launch at 7:30 GMT, that the craft's orbit's axes were 332  km (206.3  mi) and 348  km (216.24  mi), and its orbit was titled 50.2 degrees to the equator.[4]

Second flight

The vehicle's second launch was on August 8, 2022.[6] Commentators speculated on the length of this mission, when it flew over the Lop Nur base in Xinjiang, the site where the first mission landed, without landing. US satellite tracking officials report they are tracking seven objects associated with this launch. They suspect four of them are debris, while two of them may be observation platforms, tracking the performance of the vehicle with external cameras.

Chinese officials placed some launch debris at a college in Jiyuan City, Henan Province, stirring questions, as technology reporters who viewed the debris thought it included a "loading crank" similar to the one used to separate an eight ton component of its Chinese space station from it launch vehicle.[6]

Specifications

Chen Hongbo, of China Aerospace Science and Technology Corporation (CASC), the main contractor for China's space agency, said during a 2017 interview that China's space plane would be able to be re-used up to 20 times.[4][7] Chen said the vehicle's first stage would use a scramjet engine.[8]

On March 24, 2020, officials said the vehicle was designed to carry a crew of six.[9] Its takeoff weight would be 21.6 tonnes, and it would be 8.8  m (28.87  ft) long.[9]

Speculation over the spaceplane's role

When asked to speculate on the spaceplane's role Brian Weedon, director of program planning for the Secure World Foundation said, "It's a great question. We're not even really sure why the U.S. military is pursuing a space plane."[5]

McDowell speculated that the very high speeds the spaceplane underwent during re-entry might help the Chinese in their development of hypersonic missiles.[5] He added the Chinese may have thought, "If the Americans have one of those, there's got to be a good reason for it, so we better get one too."
