Beijing seeking Mars sample return proposals from SARs

China is seeking payload proposals for its Mars sample return mission and inviting overseas researchers to participate.
The China National Space Administration (CNSA) has called on overseas research institutions, including those in Hong Kong and Macau, to submit proposals for developing payloads for the Tianwen-3 mission.
The mission, a significant part of China's planetary exploration programme, is scheduled for launch around 2028.
The Tianwen-3 spacecraft comprises a lander, an ascent vehicle, a service module, an orbiter and a return module and is equipped with six scientific payloads.
The six payloads, namely, the Raman fluorescence spectrometer, ultra-wideband exploration radar, mid-infrared superfine imaging spectrometer, Mars global multicolour camera, descent ENA aurora detector and high-precision vector magnetometer, are all open to overseas researchers, according to a notice released by the CNSA.
The CNSA requires that all payload projects be led by a domestic institution, with no more than five entities involved in the joint development of a single payload.
Last month, the administration announced that it would offer payload resources for international cooperation, with up to 15 kilogrammes available on the orbiter and five kilogrammes on the service module.
The primary scientific objective of the mission is to search for signs of life on Mars.
Other areas of exploration include the Martian climate and its evolution, the planet's geology and its internal processes. (Xinhua)

'Interstellar object' spotted in Solar System
'Interstellar object' spotted in Solar System Astronomers believe a 10-20km-wide mass may be the third interstellar object to be observed in our Solar System. File photo: Reuters An object that appears to be from beyond our Solar System has been spotted hurtling towards the Sun, which if confirmed would be the third visitor from the stars ever detected, the European Space Agency said on Wednesday. The object, which is currently being referred to as A11pl3Z, poses no threat to Earth, the ESA's planetary defence head Richard Moissl told AFP. "It will fly deep through the Solar System, passing just inside the orbit of Mars," but will not hit our neighbouring planet, he said. Excited astronomers are still refining their calculations, but the object appears to be zooming more than 60 kilometres a second. This would mean it is not bound by the Sun's orbit, unlike comets and asteroids, which all originate from within the Solar System. Its trajectory also "means it's not orbiting our star, but coming from interstellar space and flying off to there again," Moissl said. "We are not 100 percent certain at the moment, but anything else would be a surprise," he added. Official confirmation is expected to come from the International Astronomical Union's Minor Planet Center, which has recorded more than 100 observations of the object so far. The NASA-funded ATLAS survey in Hawaii first discovered the object on Tuesday, US astronomer David Rankin wrote on the social media platform Bluesky. Professional and amateur astronomers across the world then searched through past telescope data, tracing its trajectory back to at least June 14. The object is currently estimated to be roughly 10-20 kilometres wide, Moissl said. But the object could be smaller if it is made out of ice, which reflects more light. "It will get brighter and closer to the Sun until late October and then still be observable (by telescope) until next year," Moissl said. It would be the third time humanity has detected something coming from the stars. The first, 'Oumuamua, was discovered in 2017. It was so strange that at least one prominent scientist became convinced it was an alien vessel – though this has since been dismissed by further research. Our second interstellar visitor, 2I/Borisov, was spotted in 2019. Mark Norris, an astronomer at the UK's University of Central Lancashire, told AFP that the new object appears to be "moving considerably faster than the other two extra-solar objects that we previously discovered." He pointed to modelling estimating that there could be as many 10,000 interstellar objects drifting through the Solar System at any given time, though most would be smaller than the newly discovered object. If true, this suggests that the newly online Vera C. Rubin Observatory in Chile could soon be finding these dim interstellar visitors every month, Norris said. (AFP)
