Wreckage of Russia's failed Mars '96 probe has been found south of the Oyuni salt plateau in Bolivia, 100km (55nm) from Chile and at an altitude of 12,000ft (3,650m). The spacecraft plunged from low Earth orbit on 17 November, 1996, after the fourth stage of its Proton launcher failed to restart. The fourth stage re-entered over the Pacific a day later.
