2025年7月30日发射的NISAR卫星捕捉了其第一批地球图像,利用双雷达系统监测土地、冰和植被的变化。 The NISAR satellite, launched July 30, 2025, captured its first Earth images, using dual radar systems to monitor changes in land, ice, and vegetation.

2025年7月30日发射的美国航天局-国际空间研究组织合成孔径雷达(NISAR)卫星捕捉了第一个地球高分辨率图像,在缅因州展示了山区沙漠岛和北达科他州的农田。 The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, launched July 30, 2025, has captured its first high-resolution images of Earth, showing Mount Desert Island in Maine and farmland in North Dakota. 利用双雷达系统 -- -- NASA的L波段和印度空间研究组织的S波段 -- -- NISAR能够通过云层和黑暗的图像,探测到小到一英寸的微小变化。 Using dual radar systems—NASA’s L-band and ISRO’s S-band—NISAR can image through clouds and darkness, detecting changes as small as fractions of an inch. 飞行任务将从747公里轨道上每隔12天扫描一次地球,提供土地、冰和植被的详细数据,用于气候研究、灾害监测和农业。 The mission will scan Earth every 12 days from a 747-kilometer orbit, providing detailed data on land, ice, and vegetation for climate research, disaster monitoring, and agriculture. 全面科学活动定于2025年11月开始,向全世界的科学家和决策者提供重要的见解。 Full science operations are set to begin in November 2025, delivering critical insights to scientists and decision-makers worldwide.
