任务简介
NASA的近地天体（NEO）探测者任务旨在推进行星防御工作，以发现和表征大多数进入地球轨道3000万英里范围内的潜在危险小行星和彗星。这些天体统称为近地天体（NEO）。 NEO探测者由一个科学仪器组成：一个直径50厘米（近20英寸）的望远镜，工作在两个热感应红外波长。它将能够探测到明亮和黑暗的小行星，后者是最难发现的一类。
原文
NASA's Near-Earth Object (NEO) Surveyor mission is designed to help advance planetary defense efforts to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit. These are collectively known as near-earth objects, or NEOs. NEO Surveyor consists of a single scientific instrument: a 50 centimeter (nearly 20 inch) diameter telescope that operates in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, which are the most difficult type to find.
