Russia’s space agency says two Russians have set a record for the longest continuous stay on the International Space Station.

Having artificial gravity would be incredibly useful to any astronaut who happens to have evolved and grown up in a gravitational field. Living in low-gravity environments for extended periods of time takes its toll on astronauts and cosmonauts, who may develop everything from puffy faces to baby feet, and that is just for starters.

Two cosmonauts have set the record for the most days spent continuously aboard the International Space Station (ISS), surpassing the previous record holders, Frank Rubio, and Russian cosmonauts Dmitry Petelin and Sergey Prokopyev.
