3 天前 · The reactivation mission was called Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). As of August 2023, NEOWISE is 40% through the 20th coverage of the full sky. Science operations and data processing for WISE and NEOWISE take place at the Infrared Processing and Analysis Center at the California Institute of ...

2024年4月11日 · NEOWISE 是近地天体宽视场红外巡天探测器（Near-Earth Object Wide-field Infrared Survey Explorer）的简称，是美国国家航空航天局（NASA）行星防御战略的重要组成部分，它帮助该机构完善小行星和彗星的轨道，同时估算它们的大小。 其中一个例子就是具有潜在危险的小行星阿波菲斯，它将于 2029 年接近我们的地球。 这幅太阳系自上而下的动画视图显示了近地天体监视卫星（NEOWISE）自2014年重新启动以来的十年间所探测到的所有小行星和彗星的位置。 资料来源：IPAC/加州理工学院/亚利桑那大学. 通过从低地轨道位置反复观测天空，NEOWISE 对 44,000 多个太阳系天体进行了 145 万次红外测量。
2024年4月11日 · NEOWISE 是近地天體寬視野紅外線巡天探測器（Near-Earth Object Wide-field Infrared Survey Explorer）的簡稱，是美國國家航空暨太空總署（NASA）行星防禦戰略的重要組成部分，它幫助該機構完善小行星和彗星的軌道，同時估算它們的大小。
2024年4月4日 · Short for Near-Earth Object Wide-field Infrared Survey Explorer, NEOWISE is a key component of NASA’s planetary defense strategy, helping the agency refine the orbits of asteroids and comets while also estimating their size. One such example is the potentially hazardous asteroid Apophis, which will make a close approach of our planet in 2029.
2024年4月4日 · This artist’s concept depicts the NEOWISE spacecraft in orbit around Earth. Launched in 2009 to survey the entire sky in infrared, the spacecraft took on a more specialized role in 2014 when it was reactivated to study near-Earth asteroids and comets.
