China has launched the Tianwen-2 spacecraft, embarking on a mission to retrieve samples from an asteroid near Mars. According to the China National Space Administration, this mission aims to "yield groundbreaking discoveries and expand humanity’s knowledge of the cosmos."
The Tianwen-2 probe was launched on Thursday from southern China, utilizing the Long March 3-B rocket. The probe is tasked with collecting samples from the asteroid 2016HO3 and exploring the main-belt comet 311P, located beyond Mars.
Shan Zhongde, head of the CNSA, stated that the Tianwen-2 mission marks a "significant step in China’s new journey of interplanetary exploration." The decade-long mission is expected to provide insights into the cosmos.
The samples from asteroid 2016HO3 are expected to be returned in approximately two years. These asteroids, selected for their stable orbits, may offer clues about Earth's formation, including the origins of water.
China earlier returned rock samples from the moon's far side back to Earth in a historic mission and has welcomed international cooperation. However, any cooperation with the U.S. hinges on removing an American law banning direct bilateral cooperation with NASA.
The near side of the moon is seen from Earth and the far side faces outer space. The far side also is known to have mountains and impact craters and is much more difficult to reach.
China also operates the three person-crewed Tiangong, or “Heavenly Palace,” space station, making the country a major player in a new era of space exploration and the use of permanent stations to conduct experiments in space, especially since the station was entirely Chinese-built after the country was excluded from the International Space Station over U.S. national security concerns.
China’s space program is controlled by the People’s Liberation Army, the military branch of the ruling Communist Party.
The country’s space program has grown rapidly in the more than 20 years since it first put a man in space, only the third country to do so under its own speed. The space agency has landed an unmanned explorer on Mars and a rover on the far side of the moon. It aims to put a person on the moon before 2030.
A future Tianwen-4 Jupiter mission will explore Jupiter, although details haven't been released.
