訪れた探査機

• Lunar Reconnaissance Orbiter — Active mission (science.nasa.gov, checked 2026-11-01). There since 2009-06-23.
• Chandrayaan-2 orbiter — Reported operating: ISRO's mission page says the orbiter is healthy in a 100 km polar orbit, but the page is undated; ISRO reported new results from its radar on 2026-05-27. No later official update found. There since 2019-08-20.
• ARTEMIS-P1 (THEMIS-B) — Active by NASA's listing: THEMIS-ARTEMIS is an "Active Mission" with two craft round the Moon (science.nasa.gov, page updated 2026-08-11), though that page does not name P1 or P2. JPL's trajectory rests on tracking through 2026-10-15 (Horizons, revised 2026-10-20), so someone was tracking it then. One of five THEMIS craft launched in 2007, sent on to the Moon, in orbit since 2011. There since 2011-06-27.
• ARTEMIS-P2 (THEMIS-C) — Active by NASA's listing: THEMIS-ARTEMIS is an "Active Mission" with two craft round the Moon (science.nasa.gov, page updated 2026-08-11), though that page does not name P1 or P2. JPL's trajectory rests on tracking through 2026-10-15 (Horizons, revised 2026-10-20), so someone was tracking it then. One of five THEMIS craft launched in 2007, sent on to the Moon, in orbit since 2011. There since 2011-07-17.
