China on Monday rejected as an irresponsible smear a warning from the chief of Nasa that China might “take over” the moon as part of a military programme, saying it has always called for the building of a community of nations in outer space.

China has stepped up the pace of its space programme in the past decade, with exploration of the moon a focus. China made its first lunar non-crewed landing in 2013 and expects to launch rockets powerful enough to send astronauts to the moon towards the end of this decade.

“We must be very concerned that China is landing on the moon and saying: ‘It’s ours now and you stay out,'” Nasa administrator Bill Nelson told German newspaper Bild in an interview published on Saturday.

The US space agency chief said China’s space programme was a military one and that China had stolen ideas and technology from others.

“This is not the first time that the head of [Nasa] has ignored the facts and spoken irresponsibly about China,” said Zhao Lijian, a spokesman at the Chinese foreign ministry.

“The US side has constantly constructed a smear campaign against China’s normal and reasonable outer space endeavours, and China firmly opposes such irresponsible remarks.”

China has always promoted the building of a shared future for humanity in outer space and opposed its weaponisation and any arms race in space, he said.

Nasa, under its Artemis programme, plans to send a crewed mission to orbit the moon in 2024 and make a crewed landing near the lunar south pole by 2025. China is planning non-crewed missions to the moon’s south pole some time this decade. — Martin Quin Pollard, (c) 2022 Reuters
