China's proposed Venus mission would investigate the planet's atmosphere and geology

中国提出的金星任务将调查金星的大气和地质

More details are emerging about China's potential mission to Venus as part of the country's expanding space exploration program.

作为中国不断扩大的太空探索计划的一部分，有关中国潜在的金星任务的更多细节正在浮出水面。

The proposed mission, called the Venus Volcano Imaging and Climate Explorer (VOICE), would launch in 2026 and arrive in orbit around the hottest and brightest planet in the solar system in 2027, according to details from a July 9 meeting to discuss the mission.

根据7月9日讨论该任务的一次会议的细节，拟议中的任务称为金星火山成像和气候探测器（VOICE），将于2026年发射，并于2027年抵达太阳系最热、最亮的行星周围的轨道。

The spacecraft would use a circular polar orbit with an altitude of 220 miles (350 kilometers) to investigate Venus' geological evolution, the thermal and chemical processes in the planet's atmosphere, the surface-atmosphere interactions, and the potential for a habitable environment and life in the Venusian clouds.

该航天器将使用一个高度为220英里（350公里）的圆形极地轨道来研究金星的地质演化、行星大气中的热和化学过程、地表-大气相互作用以及金星云中的宜居环境和生命的潜力。

Science instruments would include an S-band polarimetric synthetic aperture radar, which could peer through the Venusian clouds and map the surface, and a multispectral imager that could observe Venus in the ultraviolet, visible and near-infrared wavelengths.

科学仪器将包括一个S波段极化合成孔径雷达，可以探测金星云层并绘制表面图，以及一个多光谱成像仪，可以在紫外线、可见光和近红外波段观察金星。

VOICE is a candidate mission for a space science program somewhat separate from China's main lunar and planetary exploration missions led by the China National Space Administration (CNSA), which include the ongoing Tianwen 1 Mars mission and the planned Tianwen 2 near-Earth asteroid and Mars sample-return missions.

“声音”是一项空间科学计划的候选任务，与中国国家航天局（CNSA）领导的中国主要月球和行星探索任务有所不同，其中包括正在进行的天问1号火星任务和计划中的天问2号近地小行星和火星样本返回任务。

The proposed mission is instead being assessed as one of 13 candidate missions under the third Strategic Priority Program (SPP) on Space Science led by the Chinese Academy of Sciences. The VOICE mission appears to be competing with three others in the category of planetary and Earth science: the E-type Asteroid Sample Return mission to collect samples from the asteroid 1989 ML and deliver them to Earth, the low Earth orbit Climate and Atmospheric Components Exploring Satellites mission, and the Ocean Surface Current multiscale Observation Mission.

该拟议任务被评估为中国科学院领导的空间科学第三战略优先计划（SPP）下的13项候选任务之一。“声音”任务似乎与行星和地球科学领域的其他三项任务竞争：E型小行星样本返回任务，从小行星1989 ML收集样本并将其传送到地球，低地球轨道气候和大气成分探测卫星任务，以及海洋表面流多尺度观测任务。

It is not clear how many missions will be approved, but the candidates will be evaluated in the near future based on the available budget, technology readiness and manufacturing schedule.

目前尚不清楚将批准多少特派团，但将在不久的将来根据现有预算、技术准备和制造时间表对候选人进行评估。

Other proposals are in the fields of astronomy and astrophysics, exoplanets (the Closeby Habitable Exoplanet Survey and Earth 2.0 telescopes) and heliophysics.

其他建议涉及天文学和天体物理学、系外行星（近距离可居住系外行星调查和地球2.0望远镜）和太阳物理领域。

The first round of China's SPP missions saw the launch of four spacecraft, including a dark matter-hunting probe and a quantum science satellite. Second SPP round missions will include the Einstein Probe, which will launch in 2023 to investigate extreme physics, and the Solar wind Magnetosphere Ionosphere Link Explorer, a collaboration with the European Space Agency (ESA) to explore interactions between the sun and Earth.

中国SPP任务的第一轮发射了四个航天器，包括一个暗物质搜寻探测器和一颗量子科学卫星。第二轮SPP任务将包括爱因斯坦探测器，该探测器将于2023年发射，用于研究极端物理，以及太阳风磁层电离层链接探测器，这是与欧洲航天局（ESA）合作探索太阳和地球之间相互作用的项目。

The third round of missions would likely launch between 2026 and the end of the decade.

第三轮任务可能会在2026年至本十年结束之间发射。

If selected, VOICE would join a pair of NASA missions to Venus (VERITAS and DAVINCI+), and ESA's EnVision spacecraft as part of a wave of renewed interest in Venus.

如果被选中，VOICE将加入美国宇航局对金星的两项任务（VERITAS和DAVINCI+），以及欧洲航天局的设想航天器，作为对金星重新产生兴趣的一部分。

In addition, California-based Rocket Lab aims to launch a private Venus mission in 2023, and India plans to send the Shukrayaan orbiter to space a year later. Russia has also announced plans for a mission named Venera-D, scheduled to launch in 2029. Potential NASA involvement in the mission was ended by Russia's invasion of Ukraine.

此外，位于加利福尼亚州的火箭实验室计划在2023年发射一个私人金星任务，印度计划在一年后将Shukrayan轨道器送入太空。俄罗斯还宣布了名为Venera-D的任务计划，计划于2029年发射。美国宇航局参与该任务的可能性因俄罗斯入侵乌克兰而终止。
