DARE任务设计：来自低高度冻结月球轨道的低RFI观测
DARE Mission Design: Low RFI Observations from a Low-Altitude Frozen Lunar Orbit
摘要：
黑暗时代无线电实验（DARE）旨在研究宇宙大爆炸后约8000万至4.2亿年的宇宙黑暗时代。观测需要真正安静的无线电条件，屏蔽太阳和地球电磁（EM）发射，在月球的远端。DARE的科学轨道是一个相对于月球引力摄动的冻结轨道。轨道的高度和方向几乎无限期地保持固定，最大限度地延长了科学时间，而无需维护。DARE的测量觇标避开了银河系中心，从而能够对宇宙中的第一批恒星和星系进行研究。
英文摘要：
The Dark Ages Radio Experiment (DARE) seeks to study the cosmic Dark Ages approximately 80 to 420 million years after the Big Bang. Observations require truly quiet radio conditions, shielded from Sun and Earth electromagnetic (EM) emissions, on the far side of the Moon. DARE's science orbit is a frozen orbit with respect to lunar gravitational perturbations. The altitude and orientation of the orbit remain nearly fixed indefinitely, maximizing science time without the need for maintenance. DARE's observation targets avoid the galactic center and enable investigation of the universe's first stars and galaxies.
