CAPE CANAVERAL – A SpaceX Cargo Dragon completed its month long stay at the International Space Station (ISS), departing from the orbiting outpost Thursday morning, Sept. 30, and accomplished a safe and successful splashdown hours later in the Atlantic Ocean that evening off the east coast of Florida returning home with some 2.3 tons of research samples and cargo – located north of the Kennedy Space Center (KSC) where the commercial resupply mission for NASA began in late August.
The SpaceX CRS-23 Cargo Dragon undocked from the station’s forward port on the Harmony module at 9:12 a.m. EDT, (1312 GMT) Sept. 30 and reentered the Earth’s atmosphere blazing across the nighttime sky for a splashdown some 14 hours later at around 11 p.m. ET.

The undocking was carried live on NASA TV but the evening splashdown was not.
NASA Flight Engineer Shane Kimbrough was on duty monitoring the SpaceX Cargo Dragon vehicle during its automated undocking after hooks and latches were released and the craft fired thrusters to move a safe distance away.

Overall this marked the 23rd NASA contracted resupply mission by SpaceX and it began by hauling up two tons of science and research investigations and supplies for NASA from Florida’s Spaceport.
Dragon orbited Earth for another half a day before parachuting to the splashdown.

NASA and SpaceX personnel were aboard support boats “ready to retrieve the cargo craft containing station hardware and completed science experiments for analysis.”
SpaceX utilized the GO Searcher recovery vessel to haul Dragon from the ocean water and then returned it to Port Canaveral Friday later afternoon, Oct. 1, for unloading and eventual reuse.
“Splashing down off the coast of Florida enables quick transportation of the science aboard the capsule to the agency’s Kennedy Space Center’s Space Station Processing Facility, delivering some science back into the hands of the researchers hours after splashdown. This shorter transportation timeframe allows researchers to collect data with minimal loss of microgravity effects,” say NASA officials.
The mission began with liftoff of the flight proven two stage 215-foot-tall (65-meter) Falcon 9 on the NASA SpaceX CRS-23 Cargo Dragon to the ISS at 3:14 am. EDT (714 GMT) on August 29 from Launch Complex-39A on NASA’s Kennedy Space Center in Florida during an instantaneous launch window.
Eight and a half minutes later the recycled Falcon 9 first stage launched for the fourth time safely touched down intact and upright on SpaceX’s newest droneship stationed in the Atlantic Ocean named ‘A Shortfall of Gravitas’ or ASOG on its maiden booster recovery mission.
Overall the CRS-23 mission marked the 90th successful recovery of a first stage by SpaceX by land or by sea.
This reused Falcon 9 previously launched on the Crew-1, Crew-2 and a commercial mission for SpaceX.
The SpaceX cargo Dragon flew for the second time and was carrying more than 4,800 pounds (2207 kg) of science experiments, crew supplies, and spacecraft hardware for NASA to the ISS and its seven person multinational crew of astronauts and cosmonauts.
The next Dragon to fly will be a Crew Dragon on Oct. 30 carrying the multnational crew of 4 astronauts from the US and Germany to the ISS.
Crew-3 will replace Crew-2 after a short handover period.
