A few hours ago, astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner returned to Earth on the Soyuz MS-16 spacecraft, that landed in Kazakhstan. The three of them spent a bit more than 6 months on the International Space Station, where they arrived on April 9, 2020 as part of Expedition 62. After landing, they were assisted by a skeleton crew with the precautions needed to avoid the risk of Covid-19 infection.
