How a single radio advertisement launched a British astronaut into orbit
In short: In 1989, a food technologist heard a peculiar plea on her car radio: 'Astronaut wanted. No experience necessary.' This unlikely start led Helen Sharman to the Mir space station, protected by a specialized suit designed to prevent a fatal tragedy.
Helen Sharamb, Britain's first astronaut, began her journey as a food technologist after responding to a radio advertisement. Selected from a pool of over 13,000 applicants for the British Juno Mission, she underwent 18 months of rigorous training in Star City. This preparation included enduring the centrifuge to simulate g-forces and training in hydro tanks for spacewalks. Alongside Timothy Mace, she was chosen to represent the mission. This intense preparation was part of a broader effort to ensure the crew could withstand the extreme environments of space travel.
The suit she relied on was the Sokol, manufactured by the Zvezda enterprise. The Sokol's design was a direct response to the 1971 Soyuz-11 tragedy, where cosmonauts Georgi Dobrovolsky, Vladislav Volkov, and Viktor Patsaev died after their descent module lost pressure. Following this disaster, Zvezda developed the Sokol-K suit within just one year. The technology evolved from high-altitude jet pilot pressure suits, essentially acting as a person-shaped, pressurized bag to provide oxygen and combat low pressure. The Zvezda institution, established in 1952 in Tomilino, has been the gateway for every cosmonaut since Yuri Gagarin. Its long-standing expertise in life-support systems remains central to the Russian space program.
Precision was vital for Sharman's safety during the high-risk phases of her 1991 mission to the Mir space station, such as docking, undocking, and landing. To ensure the suit could protect her during potential cabin depressurization, she was measured in 54 different places. This level of customization was necessary because earlier testing in 'off the shelf' suits, which were designed for men, had proven significantly uncomfortable. The Sokol, which translates to 'Falcon', provided a vital safeguard against the perils of the abyss. This engineering feat ensures that even during the most dangerous stages of flight, the astronaut remains encased in a protective cocoon.
