This month we are celebrating 20 years of continuous human presence on the International Space Station (ISS)! In honor of this major milestone, we are featuring ISS themed trivia questions. Test your knowledge below!
How many Extravehicular Activities (EVA) have been conducted on station since Dec. 1998?
According to NASA, there have been over 227 EVAs conducted on station since Dec. 1998, spanning two decades of continuous human presence onboard the orbital laboratory! Spacewalks have played a key role in station maintenance, assembly, and the installation of important upgrades. In fact, NASA reports that more than 405 EVA hours have been dedicated to station upgrades and repairs. EVAs are a critical part of the job for astronauts, and they receive extensive training on how to conduct their spacewalks here on Earth, in specialized training facilities like the Neutral Buoyancy Lab, which simulates spacewalk missions for the crew. EVAs are truly a unique experience for astronauts, but they are not without their risks. In fact, ESA (European Space Agency) astronaut Luca Parmitano had a spacesuit malfunction threaten his life during an EVA when leaked water entered his helmet, covering his eyes and nose. Luckily, Parmitano was able to get back inside the ISS just in time! There have been milestone spacewalks too, like the first all-woman EVA, conducted last year by NASA astronauts Christina Koch and Jessica Meir, and there will be many more EVAs to come as international crews continue the work to keep the world's leading orbital laboratory up and running.
