Best Space Station Science Pictures of 2021

It has been a busy year of research aboard the International Space Station.

NASA's SpaceX Crew-1, Crew-2, and Crew-3 missions supported hundreds of science experiments aboard the orbiting laboratory. Multiple Soyuz spacecrafts carried astronauts to and from station. An upgraded cargo Dragon spacecraft returned time-sensitive research to scientists on the ground. Astronauts and cosmonauts conducted 13 spacewalks. Their work included installing new solar panels to augment and upgrade the station’s power supply. Chiles and lettuce were harvested as a part of plant research preparing us for deep space missions, and technologies were tested for the upcoming Artemis missions to the Moon.
