Rank 18 documents Phobos 2 — the Soviet Mars orbiter that entered Martian orbit in January 1989 and lost contact two months later during its planned Phobos moon approach. Launched 12 July 1988 aboard Proton-K from Baikonur as the companion to Phobos 1, the Lavochkin-built bus carried plasma instruments, imaging systems, and two landers intended for the Martian moon surface. Phobos 2 successfully transmitted Mars observations and Phobos approach imagery before an unexplained shutdown on 27 March 1989 — roughly 50 seconds before a scheduled close flyby that should have deployed a hopper lander. The mission mapped both the red planet and its cratered moon before signal loss, adding to Soviet Mars programme lore alongside Mars 3's partial success. Wallimilist renders the interplanetary bus with parabolic dish, Mars-Phobos flyby geometry, purple-violet star field, cream angular-wedge lower register with PHOBOS 2 slab title, ENTERED MARS ORBIT kicker, and MAPPED MARS AND PHOBOS BEFORE SIGNAL LOSS footer exactly as the master PNG dictates — Lavochkin and Phobos 2 emblems, specimen data bands, and curator copy on Mars exploration heritage.
