1967

Mark Hart

Mark Hart, Ayvian's eldest brother, joined the early space program in the 1960s, driven by the same passion for exploration that ran in the Hart family. He was close friends with fellow astronaut Virgil Grissom.

On June 8th, 1967, during a rocket test launch, a catastrophic malfunction occurred during takeoff. The vehicle exploded on the launch pad, killing him instantly.

This tragedy would mark the beginning of the Hart family's heartbreaking connection to the dangers of space exploration.
