On yesterday's spacewalk, astronauts @Astro_SEAL and @AstroBehnken each made their 10th spacewalk, tying the record for most by @NASA_Astronauts. Cassidy is now 9th among Americans for most hours spacewalking, and Behnken is fourth. Congratulations! https://t.co/ltAGBqgAPo https://t.co/OBTNeqPGih — PolitiTweet.org

Repressurization has begun, and the spacewalk has officially concluded at 12:41 ET. The spacewalk lasted about 5 hours and 29 minutes. Great work to @AstroBehnken and @Astro_SEAL, who are now waiting inside the airlock preparing to join their crewmates and doff their spacesuits! https://t.co/73jUajmjqa — PolitiTweet.org

As @AstroBehnken and @Astro_SEAL wait to close the hatch after today's successful spacewalk, do you think they're considering that we're within a few months of celebrating 20 years of continuous human presence on the @Space_Station? Probably not, but we are. #SpaceStation20th https://t.co/w9plz7pgDY — PolitiTweet.org
