任务简介

JPSS 是 NOAA 与 NASA 的合作项目。JPSS-2 是构成 JPSS 星座的五颗卫星之一。这些航天器收集大气、陆地和海洋条件的全球测量数据，包括海面和陆地温度、植被、云层、降雨、冰雪覆盖、火灾位置和烟羽、大气温度、水汽和臭氧。 LOFTID 是充气式隔热罩技术的技术演示。在 JPSS 2 分离后，它将尝试从轨道再入大气层并幸存。此次测试将验证该技术在各种应用中的可行性，例如在火星上着陆大型有效载荷以及 ULA 的火神火箭发动机复用。

原文

JPSS is a collaborative program between NOAA and NASA. JPSS-2 is one of five satellites that will comprise the JPSS constellation. These spacecraft gather global measurements of atmospheric, terrestrial and oceanic conditions, including sea and land surface temperatures, vegetation, clouds, rainfall, snow and ice cover, fire locations and smoke plumes, atmospheric temperature, water vapor and ozone. LOFTID is a tech demo for the inflatable heatshield technology. It will attempt to survive a reentry from orbit after JPSS 2 is separated. This test will validate the technology for various applications, such as landing large payloads on Mars and engine reuse on ULA’s Vulcan rocket.
