红色星球（蓝色）的景象

+

NASA’s Perseverance Mars rover snapped this view of a hill in Mars’ Jezero Crater called “Santa Cruz” on April 29, 2021, the 68th Martian day, or sol, of the mission. About 20 inches (50 centimeters) across on average, the boulders in the foreground are among the type of rocks the rover team has named “Ch’al” (the Navajo term for “frog” and pronounced “chesh”).

Composed of multiple images, this enhanced-color mosaic was created using the left- and right-eye views of Perseverance’s Mastcam-Z camera system, merging the scene into a single, wider view. Santa Cruz hill is a possible eroded remnant of Jezero Crater’s western delta. The hill is about 164 feet (50 meters) tall and was roughly 1.6 miles (2.5 kilometers) east of the rover when the photo was taken, viewed from “Van Zyl Overlook.”

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

2021年4月29日，也就是任务的第68个火星日，美国宇航局的毅力号火星车拍摄了火星耶泽罗陨石坑中一座名为“圣克鲁斯”的山丘的照片。前景中的巨石平均宽约20英寸（50厘米），是火星车团队命名为“Ch’al”（纳瓦霍语中“青蛙”的意思，发音为“chesh”）的岩石类型之一。

这种增强的彩色拼接图由多张图像组成，是使用毅力号的Mastcam-Z相机系统的左眼和右眼视图创建的，将场景合并为一个更宽的视图。圣克鲁斯山可能是杰泽罗火山口西部三角洲的侵蚀遗迹。这座山大约有164英尺（50米）高，从范·泽尔俯视区拍摄照片时，它位于火星车以东约1.6英里（2.5公里）处。

毅力号火星任务的一个关键目标是天体生物学，包括寻找古代微生物生命的迹象。火星车将描述火星的地质和过去的气候，为人类探索这颗红色星球铺平道路，并成为收集和储存火星岩石和风化层（破碎的岩石和尘埃）的第一个任务。

随后，NASA与欧洲航天局（ESA）合作，将向火星发射航天器，从火星表面收集这些密封样本，并将其返回地球进行深入分析。
