BEIJING, China, Nov 6 \u2014 The return of Shenzhou XX astronauts from China\u2019s Tiangong space station, which was originally scheduled for Wednesday, has been deferred due to safety concerns triggered by space debris impact, according to the China Manned Space Agency.<\/strong><\/p>\n

In a brief news release on Wednesday morning, the agency said the decision was made after it came to light that the spacecraft, which is tasked with bringing its three crew members back to Earth, had possibly been hit by tiny pieces of space debris.<\/p>\n

\u201cAn impact analysis and risk assessment are underway. To ensure the safety of the astronauts and the success of the mission, it has been decided that the Shenzhou XX return flight will be postponed,\u201d the agency said in its statement, without providing any new schedule for the spacecraft\u2019s return.<\/p>\n

The Shenzhou XX team \u2014 mission commander Senior Colonel Chen Dong and crew members Colonel Chen Zhongrui and Colonel Wang Jie \u2014 has been on board the Chinese space station for more than six months since their arrival on April 25.<\/p>\n

They represent China\u2019s 15th manned spaceflight and comprise the ninth group of residents aboard the Tiangong, which is currently the only operational space station independently run by a single nation.<\/p>\n

Their successors \u2014 three astronauts of the Shenzhou XXI mission \u2014 arrived at the colossal orbital outpost on Saturday, and have already taken charge of the space station.<\/p>\n

Nonfunctional, human-made objects<\/h2>\n

Space debris consists of nonfunctional, human-made objects remaining in Earth\u2019s orbit, and these objects create significant challenges for space operations.<\/p>\n

Such debris includes everything from spent rocket stages and old satellites to fragments from disintegration, erosion and collisions, and even paint flecks. Some pieces of debris may collide with operational spacecraft or cause hazards to manned spaceflights.<\/p>\n

An object measuring 1 centimeter in diameter and moving at 17,000 kilometers per hour could deliver as much energy as a hand grenade, and destroy a spacecraft, experts said.<\/p>\n

According to an estimation by the international space community, there are more than 100 million pieces of space debris smaller than 1 cm, with a combined weight of thousands of metric tons. Impacts by these hypervelocity projectiles can cause erosive damage and disable spacecraft.<\/p>\n

It is not uncommon for spacecraft to be hit and damaged by debris. The International Space Station \u2014 the largest asset ever built in Earth\u2019s orbit by humans \u2014 has recorded more than 1,000 meteoroid and debris impacts, and has conducted orbital maneuvers many times to avoid such collisions.<\/p>\n
