Fobos 1:
Fobos 1 and 2 were part of an ambitious
Russian plant to explore Mars and its 27-kilometer-diameter
moon Phobos. Each
spacecraft comprised a orbiter for longterm
studies of the planet and a lander to study geological and climatic conditions on Phobos.
Contact was lost with the Fobos 1 before it reached Mars. The spacecraft flew past Mars without activating its science instruments or deploying its lander.
