Lunar Ephemeris Service

機械支援の翻訳下書き (Japanese) for "Lunar Ephemeris Service": Lunar Ephemeris Service is a space data service that publishes precise position and velocity data for mission planning for Moon surface and cislunar mission operations. It uses orbit determination, time standards, and versioned trajectory products so teams can align navigation, communications, and safety analysis while keeping evidence, reliability, and public-safe operational boundaries clear.

“例文の下書き: The mission team used Lunar Ephemeris Service when the lander crossed into a polar shadow region, so the team could align navigation, communications, and safety analysis before the next mission decision point.”
