What happened on the @Space_Station this week? The crew is keeping busy with science before @AstroBehnken and @Astro_Doug part ways, with their coming return to Earth aboard the @SpaceX Dragon Endeavour. Watch this week’s episode of #SpaceToGround: https://t.co/n3FAivdPUE https://t.co/7ZXsKJXhvd — PolitiTweet.org

@beermeone Weather permitting, the crew's undocking from the @Space_Station remains scheduled for approximately 7:34 p.m. EDT Saturday, Aug. 1, and splashdown at 2:42 p.m. EDT on Sunday. https://t.co/8FKbnKGqlw — PolitiTweet.org

HATCH OPEN: Once onboard the recovery ship, the hatch is opened before @AstroBehnken and @Astro_Doug are assisted out of the capsule and welcomed home to Planet Earth. https://t.co/3EPzlahreq — PolitiTweet.org

NASA @NASA

RECOVERY OPERATIONS: @AstroBehnken and @Astro_Doug will remain inside the capsule while teams from @SpaceX and our @Commercial_Crew Program approach and hoist the capsule onto the recovery ship. https://t.co/E0N5doucn6 — PolitiTweet.org

NASA @NASA

SPLASHDOWN: The main parachutes continue to carry Dragon down at a slight angle until it splashes down off the Florida coast. https://t.co/JQT216U80r — PolitiTweet.org

NASA @NASA

MAIN PARACHUTE DEPLOY: At roughly 6,500 feet in altitude, the Drogues detach from the capsule and release four main parachutes to continue slowing Dragon down to around 119mph. https://t.co/ObM4bX7ryQ — PolitiTweet.org

NASA @NASA

DROGUE PARACHUTE DEPLOY: At roughly 18,000 feet in altitude, Dragon automatically deploys two drogue parachutes to initially begin slowing down the spacecraft from its current speed of about 350mph. https://t.co/lGagK2UpyJ — PolitiTweet.org

NASA @NASA

COMMUNICATION BLACKOUT AND ATMOSPHERIC REENTRY: Dragon experiences significant heating and drag as it re-enters Earth's atmosphere, which slows the velocity to the point of safe parachute deploy. https://t.co/I1XX8hCj8C — PolitiTweet.org

NASA @NASA

NOSECONE CLOSE: Dragon’s protective nosecone covers the forward bulkhead thrusters, docking ring and number of other sensors used for approach and rendezvous with the @Space_Station. https://t.co/Zz16ph0nm0 — PolitiTweet.org

NASA @NASA

DEORBIT BURN: Dragon fires forward bulkhead thrusters for about twelve minutes to lower the spacecraft’s orbit until it intersects with planet Earth. https://t.co/MUx06TfFbG — PolitiTweet.org

NASA @NASA

CLAW AND TRUNK SEPARATION: The lower half of Dragon (trunk) detaches from the top half (capsule) where the crew members reside. The capsule is the only part of the spacecraft that will survive the fiery heat of reentry. https://t.co/GzupTa4YNj — PolitiTweet.org

NASA @NASA

CREW SLEEP: @AstroBehnken & @Astro_Doug have a ten-hour sleep period, as it is expected to take roughly 19 hours from undocking to splashdown. https://t.co/LVEZCXGLoo — PolitiTweet.org

NASA @NASA

PHASING BURNS: Prior to Dragon's deorbit burn, the flight computer jettisons the trunk in order to reduce mass and save propellant. https://t.co/DAYI0x8lTN — PolitiTweet.org

NASA @NASA

DEPARTURE BURNS: Immediately after separation, Dragon performs a series of orbit-lowering maneuvers that line up its ground track with the planned landing location. https://t.co/6YBEdUzGmX — PolitiTweet.org

NASA @NASA

SEPARATION: Crew Dragon autonomously undocks from the @Space_Station and performs a departure burn to move away from our orbiting laboratory. https://t.co/Jfk8sWKjsZ — PolitiTweet.org

NASA @NASA

GO/NO GO FOR UNDOCKING: Teams on the ground assess readiness of the spacecraft, the crew, and the @Space_Station for Dragon's departure. https://t.co/ccOkfDsAqN — PolitiTweet.org

NASA @NASA

VESTIBULE DEPRESSURIZATION: Valves remove the air from Dragon, taking it near vacuum. https://t.co/3Tx6b563pF — PolitiTweet.org

NASA @NASA

SPACE STATION HATCH CLOSURE: International @Space_Station commander @Astro_SEAL closes the hatch on our orbiting laboratory, creating an area between the spacecraft and station known as 'the vestibule'. https://t.co/tW8j79VEGn — PolitiTweet.org

NASA @NASA

HATCH CLOSURE: The hatch closes on the Dragon-side to get the spacecraft sealed up and ready for departure. https://t.co/fUM2AjLK9U — PolitiTweet.org

"With these last two months, it's been fantastic to have buddies... I'll definitely miss them when they head back." @Astro_SEAL discusses what @AstroBehnken and @Astro_Doug added to the @Space_Station team. #LaunchAmerica https://t.co/JPFRsMKgMD — PolitiTweet.org

NASA @NASA

"I think that's probably the thing that's most impressive about that team — is that willingness to continue to improve." @AstroBehnken comments on how @SpaceX has been working tirelessly to ensure his and @Astro_Doug's safety while they prepare to come home. #LaunchAmerica https://t.co/fReHHlad79 — PolitiTweet.org

NASA @NASA

"We won't leave the @Space_Station without some good landing opportunities in front of us." @AstroBehnken explains how #LaunchAmerica teams on the ground are monitoring the weather closely to ensure a safe splashdown. https://t.co/b274ljUgJF — PolitiTweet.org

NASA @NASA

"I still don't feel nervous... We're focused on the things that we need to do in order to be as safe as possible as we come back." @AstroBehnken explains how he and @Astro_Doug are preparing for the journey back home. #LaunchAmerica https://t.co/GXy33bbaHV — PolitiTweet.org

What happens after splashdown? 🤔 @Astro_Doug explains step by step how the @SpaceX Dragon Endeavour will be recovered after he and @AstroBehnken arrive back to Earth after two months aboard the @Space_Station: https://t.co/hM13hK7pnh — PolitiTweet.org

NASA @NASA

"For the most part we've had pretty good luck with Endeavour... and so we expect nothing different for the splashdown." @Astro_Doug is looking forward to flying the @SpaceX Dragon Endeavour back to Earth tomorrow.
