How astronauts survive the bumpy descent from the International Space Station
In short: After 186 days orbiting the planet, Tim Peake and his crew faced a high-stakes return to Earth. To survive the descent, they relied on a combination of parachutes and retro-rockets, all while strapped into specialized spring-loaded seats designed to cushion the impact of a heavy landing.
On June 18, 2016, the Soyuz spacecraft successfully detached from the International Space Station (ISS) to begin its three-hour journey back to Earth. The crew included NASA's Tim Kopra, Roscosmos's Yuri Malenchenko, and the European Space Agency's (ESA) Tim Peake. Their return was marked by a traditional ceremony in Kazakhstan, following a mission that lasted 186 days.
The descent process is a delicate mechanical dance. To slow the spacecraft's fall toward the ground, parachutes are deployed, supplemented by special rockets that fire moments before impact. To protect the astronauts from the resulting jolts, they are secured into moulded seats equipped with powerful springs, intended to absorb the energy of a bumpy landing.
For Tim Peake, the mission—known as Principia—was more than just a transit. During his six months aboard the ISS, he participated in diverse experiments to benefit future deep-space travel. Researchers studied his lung function and sleeping patterns to understand how humans adapt to life without natural daylight. They also meticulously tracked his food consumption to estimate the energy requirements for astronauts venturing much further from Earth. Beyond these studies, Peake performed a spacewalk and assisted in docking two separate spacecraft.
While Peake and his crewmates returned to Earth, the station's operations continued. At the time of his return, three astronauts remained on the ISS, with three more scheduled to arrive on July 7 to bring the total crew to six.
