>Plans for future space exploration
火星采样返回、木星系探测提上日程
China is making plans for the future development of its space program, including exploring asteroids and the Jovian system, collecting samples from Mars and exploring the polar region of the moon, an official from the China National Space Administration said on Saturday. Xu Hongliang, speaking for the space agency, said at a press conference that in about the year 2025 China plans to launch a probe to collect samples from a near-Earth asteroid and explore a comet in one mission.
国家航天局新闻发言人许洪亮6月12日在新闻发布会上介绍我国太空项目未来规划，表示我国将开展小行星和木星系探测、火星取样、月球极区探测等任务。许洪亮表示，2025年前后，我国将实施近地小行星取样返回和主带彗星环绕探测任务；
China plans to launch a Mars sample-return mission and a Jovian system exploration mission sometime in about 2030, Xu said.
2030年左右，我国将实施火星取样返回任务，还将实施木星系的环绕探测任务；
In addition, China plans to launch the Chang'e-6 and Chang'e-7 lunar probes in the coming five years to explore the environment and resources and collect samples from the polar region of the moon, Xu said.
"十四五"时期，我国将发射嫦娥六号、七号探测器，实施月球极区环境与资源勘查、月球极区采样返回等任务；
By the end of 2022, China will have completed the construction of its space station, in which astronauts can stay for prolonged periods to carry out scientific experiments, Xu said.

>New Southern Ocean recognized
国家地理:四大洋变五大洋
Anyone who thought the world had four oceans will now have to think again, after the National Geographic Society announced it would recognize a new Southern Ocean in Antarctica, bringing the global total to five.
认为世界上有四大洋的人要再想想了。美国国家地理学会宣布，正式认定南大洋为一个新的大洋，这样一来，四大洋就变成五大洋了。
National Geographic said the Southern Ocean consists of the waters surrounding Antarctica, out to 60-degrees south latitude.
美国国家地理学会称，南大洋由南极洲周围海域构成，从大陆的海岸线延伸至南纬60度。
National Geographic Society geographer Alex Tait said scientists have long known that the waters surrounding Antarctica form a "distinct ecological region defined, by ocean currents and temperatures".
国家地理学会的地理学家亚历克斯•泰特称，科学家很早以前就知道南极洲四周水域组成了一个"由洋流和温度界定的独特生态区域"。
"We think it's really important from an educational standpoint, as well as from a map-labeling standpoint, to bring attention to the Southern Ocean as a fifth ocean," Tait said. "So when students learn about parts of the ocean world, they learn it's an interconnected ocean, and they learn there are these regions called oceans that are really important, and there's a distinct one in the icy waters around Antarctica."
泰特称："我们认为，站在教育和地图注记的立场上，将南大洋认定为第五大洋真的很重要。这样，当学生学习海洋世界的各个部分时，他们会了解到这是一个互联互通的海洋，并了解到各个非常重要的大洋，包括环绕南极洲的这片独特的冰冷水域。"
