The return marked the end of SpaceX\u2019s 13th operational resupply flight to the space station under contract to NASA. Twelve of the missions have been successful, in addition to a round-trip test flight to the orbiting complex in 2012.<\/p>\n<p><iframe id=\"twitter-widget-0\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: absolute; visibility: hidden; width: 0px; height: 0px; display: block; flex-grow: 1;\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?dnt=false&amp;embedId=twitter-widget-0&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=952203503916630016&amp;lang=en&amp;origin=https%3A%2F%2Fspaceflightnow.com%2F2018%2F01%2F13%2Fcommercial-cargo-craft-splashes-down-in-pacific-ocean-after-station-resupply-run%2F&amp;sessionId=588e29ef739f7f69dd69bc92ee635a11cd417114&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"952203503916630016\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-lang=\"en\" data-twitter-extracted-i178269966140085497=\"true\">\n<p dir=\"ltr\" lang=\"en\">Good splashdown of Dragon confirmed, completing the second resupply mission to and from the @Space_Station with a flight-proven commercial spacecraft.<\/p>\n<p>\u2014 SpaceX (@SpaceX) January 13, 2018<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>NASA has awarded SpaceX a contract for 20 cargo missions through the end of 2019 \u2014 with 13 now in the books \u2014 and the space agency has a follow-on agreement for at least six more Dragon resupply flights from 2020 through 2024.<\/p>\n<p>Time-sensitive refrigerated specimens, such as blood and urine, and live rodents that returned to Earth inside Dragon for an experiment investigating muscle wasting in microgravity will be handed over to scientists in the next couple of days. The rest of the cargo will be unloaded from the Dragon\u2019s pressurized module and turned over to NASA and research teams once the capsule travels to SpaceX\u2019s test facility in McGregor, Texas, for post-flight processing.<\/p>\n<p>Other items packed inside the Dragon by station astronauts included specimens from a plant growth experiment that studied how vegetation responds to reduced oxygen, which can occur in flooding on Earth.<\/p>\n<p>The commercial company Made in Space also sent up a privately-funded technological experiment to study how optical fiber could be produced in orbit \u2014 perhaps with better quality than the silica-based fiber optic cables manufactured on Earth. The results were aboard Dragon on the trip home Saturday.<\/p>\n<p>The Dragon capsule lifted off Dec. 15 aboard a Falcon 9 rocket from Cape Canaveral, and it arrived at the space station two days later with 2.4 tons of food, supplies and experiments.<\/p>\n<p>The Dec. 15 launch was the first time NASA has entrusted cargo to launch on a previously-flown Falcon 9 rocket booster. The mission also used a recycled Dragon cargo module that first flew on a trip to the station and back in April and May of 2015.<\/p>\n<figure id=\"attachment_29702\" aria-describedby=\"caption-attachment-29702\" style=\"width: 676px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-29702\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/01\/spacex.png\" alt=\"\" width=\"676\" height=\"380\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/01\/spacex.png 900w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/01\/spacex-300x169.png 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/01\/spacex-768x432.png 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2018\/01\/spacex-678x381.png 678w\" sizes=\"(max-width: 676px) 100vw, 676px\"><figcaption id=\"caption-attachment-29702\" class=\"wp-caption-text\">A breakdown of the return cargo manifest.

The trunk section is designed to burn up on re-entry, while the primary module parachutes back to Earth.<\/p>\n<p>The arm removed the Dragon capsule from its berthing port on the station\u2019s Harmony module Friday in preparation for departure Saturday.<\/p>\n<p>Using a command issued from the Canadian Space Agency\u2019s control center, the robot arm released the Dragon spacecraft at 4:58 a.m. EST (0958 GMT) Saturday. It was the first time a visiting vehicle was released from the station via a ground command.<\/p>\n<p>Astronauts Joe Acaba and Scott Tingle monitored the departure maneuvers, and the Dragon backed away with a series of three thruster firings to set up for a de-orbit burn at 9:43 a.m. EST (1443 GMT).<\/p>\n<p>The de-orbit burn dropped the low point of the Dragon spacecraft\u2019s orbit back into Earth\u2019s atmosphere, low enough for it to be captured by aerodynamic drag and head for splashdown in the Pacific Ocean.<\/p>\n<p>SpaceX\u2019s 14th commercial resupply flight to the station is scheduled for launch April 2.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Dragon spacecraft is pictured soon after its release from the International Space Station on Saturday.
