猎鹰 9 Block 5 | SPHEREx & PUNCH

SPHEREx is a planned two-year astrophysics mission to survey the sky in the near-infrared light, which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions involving the birth of the universe, and the subsequent development of galaxies. It also will search for water and organic molecules – essentials for life as we know it – in regions where stars are born from gas and dust, known as stellar nurseries, as well as disks around stars where new planets could be forming. Astronomers will use the mission to gather data on more than 300 million galaxies, as well as more than 100 million stars in our own Milky Way galaxy. NASA’s Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will share a ride to space with SPHEREx. It consists of four suitcase-sized satellites, which will focus on the Sun’s outer atmosphere (the corona) and how it generates the solar wind. The spacecraft also will track coronal mass ejections – large eruptions of solar material that can drive large space weather events near Earth – to better understand their evolution and develop new techniques for predicting such eruptions.

SPHEREx 是一项计划中为期两年的天体物理学任务，将在近红外光波段对全天进行巡天。近红外光虽人眼不可见，却是回答涉及宇宙诞生及此后星系发育等宇宙问题的有力工具。 它还将在恒星由气体与尘埃诞生的区域（即“恒星摇篮”）以及恒星周围可能形成新行星的盘中，搜寻水和有机分子——这些是我们所知生命的必需品。天文学家将利用该任务收集超过 3 亿个星系以及我们银河系内超过 1 亿颗恒星的数据。 NASA 的“统一日冕与日球层偏振计”（PUNCH）任务将与 SPHEREx 共享一次发射。它由四颗手提箱大小的卫星组成，将聚焦于太阳外层大气（日冕）及其如何产生太阳风。该航天器还将追踪日冕物质抛射——可在地球附近引发大型空间天气事件的太阳物质大规模喷发——以更好地理解其演变，并开发预测此类喷发的新技术。
