Two Soviet probes were sent to Mars in 1988 as part of the Phobos program.

The Soviet probe Lunik 3 launched on October 4 and photographed the far side two days later.

The last Soviet lunar probe to land on the Moon was Luna 23.

Luna 5 became the first Soviet probe to be successfully launched towards the Moon in two years.

Only you backed it up by somehow destroying three Soviet lunar probes.

Meanwhile, the first large Soviet probe into the city was put into operation.

The Soviet probe is an ambitious and impressive project, Dr. Murray said.

Ten Soviet probes have achieved a soft landing on the surface, with up to 110 minutes of communication from the surface, all without return.

Soviet probes battle extreme conditions on Venus.

In 1959 the Soviet probe Luna 2 became the first spacecraft to crash into the Moon.
