Vladimir Mikhaylovich Komarov (cosmonaut)

Владимир Михайлович Комаров

1927–1967 ✕ Soyuz 1 crash on return

Voskhod 1 commander and the first human to perish in a spaceflight

"I cannot orient the spacecraft to the sun" — amid cascading failures aboard Soyuz 1, Komarov continued manual troubleshooting and reporting to ground control until the final descent.

A Soviet Air Force test pilot and aerospace engineer, he commanded Voskhod 1 in 1964, the world's first multi-crew spaceflight. One of only two cosmonauts in the first group to hold an Air Force Academy engineering degree, he contributed significantly to Vostok and Voskhod spacecraft design and to cosmonaut training evaluation. In 1967 he flew Soyuz 1 solo on its first crewed test flight; after re-entry, a parachute failure caused the capsule to crash, making him the first human to die in a spaceflight. His death forced a fundamental review of design verification and safety procedures across the Soviet crewed space program.
