Goals: Mars 8 was an ambitious, multi-faceted Russian-led international mission to simultaneously explore the Martian atmosphere, surface and interior. The mission included an orbiter, two small science landers and two penetrators -- carrying 38 sophisticated science instruments.

Accomplishments: A malfunction in Earth orbit sent the spacecraft plunging back into the atmosphere. It broke up on re-entry and debris were reportedly scattered in a wide area across the Pacific Ocean, Chile and Bolivia.
