Before rockets, the edge of space belonged to balloonists in pressurized gondolas. Auguste Piccard reached 15,785 metres in 1931; the Soviet Osoaviakhim-1 crew of three died in 1934 when their record-setting flight iced up and broke apart; the US Explorer II crew touched 22,066 metres in 1935, photographing the curve of the Earth. The trade produced the pressure suits and cabin technology astronauts inherited, then vanished when rockets made balloons look slow — its last practitioner, Nick Piantanida, died in a 1966 jump attempt.
Stratonaut no longer exists as a living trade. Here is what erased it, and which profession took on the work.
1957–1969
Test pilots with a new job title
The first astronauts were chosen for the ability to stay useful inside a malfunctioning machine: military test pilots, screened by intrusive medical programs neither country fully understood the need for. Mercury, Vostok and Gemini flights lasted hours to days, and the crews fought their own engineers for the right to actually fly the vehicles — a struggle Tom Wolfe later immortalized as the argument over whether they were pilots or "Spam in a can."
What else was happening then
1959
The Mercury Seven
On 9 April 1959 NASA presented its first seven astronauts — all military test pilots, screened from 508 records — at a Washington press conference where reporters treated them as heroes before any had flown. The template they set, cool competence under absurd risk, defined the job's public image for decades.
1961
Gagarin orbits the Earth
On 12 April 1961, Yuri Gagarin rode Vostok 1 through a single 108-minute orbit, calling out "Poyekhali!" — "Let's go!" — at liftoff. He ejected at seven kilometres and parachuted into a Saratov field, a detail kept secret for years because record rules required landing with the craft. He launched a senior lieutenant and landed a major.
1963
Tereshkova, the first woman
Valentina Tereshkova, a 26-year-old textile-factory worker chosen for her amateur parachuting, flew 48 orbits over three days aboard Vostok 6 in June 1963 — at that point more time in space than all American astronauts combined. No other woman flew until 1982; she remains the only woman ever to fly to space alone.
1965
Leonov walks in space
On 18 March 1965 Alexei Leonov floated out of Voskhod 2 for twelve minutes — and nearly died returning: his suit had ballooned rigid in vacuum, and he silently vented its pressure toward the edge of decompression sickness to squeeze back into the airlock head-first. Spacewalking has been the job's defining physical craft ever since.
Where that work lives now
The rarest job on Earth is practiced off it: roughly 700 people have ever held it, from Gagarin's 108 minutes to year-long tours on the space station.
