✌️2 words. Welcome home! After 196 days living and working in Earth’s orbit aboard the ISS, NASA astronaut Chris Cassidy (astro_seal) returned from his third space mission yesterday, Oct. 21, with cosmonauts Ivan Vagner and Anatoly Ivanishin of Roscosmosofficial! While Cassidy was on the station, he completed four spacewalks and contributed to hundreds of experiments, including a study of the influence of gravity on electrolytic gas evolution, which looks at bubbles created using electrolysis. Another fun fact is that he has spent the fifth-highest total amount of days in space among U.S. astronauts at 378 days. What a ride!
