Vostok 2 — Gherman Titov spends 25 hours in space
When Gherman Titov lifted off from Baikonur at 06:00 Universal Time on 6 August 1961, he was 25 years old, and nobody knew whether a human being could survive a full day in weightlessness. Gagarin had flown a single orbit in April. Soviet physicians genuinely feared that prolonged weightlessness might disturb the inner ear, the heart, or the mind itself. Titov's assignment, flying under the callsign Oryol, "Eagle," was to find out by staying up for seventeen orbits, more than ten times longer than anyone before him.
The answers came fast, and some were unwelcome. Within hours Titov felt the world tilt and his stomach rebel; he vomited, becoming the first person to suffer space sickness, and kept working anyway. He took manual control of his spacecraft, filmed the Earth through his porthole with a handheld Konvas movie camera, the first motion pictures shot by a human in orbit, ate three meals, and then did something no one had ever done: he went to sleep, drifting off during the seventh orbit and waking more than half an hour past schedule. The body's oldest rhythm worked in orbit.
After 25 hours and 18 minutes and roughly 700,000 kilometres, Titov's capsule reentered the atmosphere. Following standard Vostok procedure he ejected and parachuted separately to the ground, landing on 7 August near Krasny Kut in the Saratov region. His space sickness, which he reported with complete honesty, founded the medical study of what is now called space adaptation syndrome. The flight proved that humans could eat, sleep, work, and recover in weightlessness, and that the road to long-duration spaceflight was open.
One record from the flight may never fall. At 25 years and 10 months, Titov remains, more than six decades later, the youngest human ever to orbit the Earth. Chosen as Gagarin's backup by the narrowest of margins, he became the second person in space but the first to truly live there. In May 1962 he toured the United States and met John Glenn at the White House, the first meeting between a cosmonaut and an astronaut.

Key Facts
Titov remains the youngest person ever to orbit the Earth, a record untouched for over six decades of spaceflight.
He was the first human to suffer space sickness, vomiting in orbit and reporting it honestly, which founded the study of space adaptation syndrome.
He was the first person to sleep in space, dozing off during the seventh orbit and waking more than half an hour late.
Using a handheld Konvas movie camera, he shot the first motion pictures of Earth taken by a human in orbit.
No American matched his flight duration until Gordon Cooper's Mercury-Atlas 9 mission in May 1963, almost two years later.
Why It Mattered
Vostok 2 settled the deepest open question of early spaceflight: whether the human body could function in weightlessness beyond a few minutes. Titov's day in orbit proved people could eat, sleep, pilot a spacecraft, and recover from sickness in space, the physiological foundation on which every space station and long-duration mission since has been built. His honest reporting of space sickness, which affects roughly half of all space travelers to this day, created space medicine's first real dataset. The flight also widened the gap with the United States, whose astronauts had logged barely half an hour of suborbital time.
