This astronaut crossed the Kármán Line (100 km), the internationally accepted boundary of space.

Crossed Kármán Line

Soyuz 15

This flight was intended to dock to the Salyut 3 space station but a failure of the docking system, a drain of propellant, and limited power forced the mission to land after just 2 days. The mission revealed that more safety improvements were needed for Soyuz.

Soyuz is a human-carrying capsule built and operated by Russia, capable of transporting up to three people to the Space Station at a time. It has been upgraded numerous times since its first use in the 1960s for the Soviet lunar program and was the only crewed vehicle for the Station from 2011 to 2020.
