Lasting approximately 20 seconds, this burn takes the spacecraft on a trajectory to the front of and below the ISS.

Once the final burn is complete, Dragon is in a stable low-Earth orbit approximately 10 km below the ISS.<\/p>\n<p>Once all departure burns were complete, the next major milestone was the separation of Dragon\u2019s trunk, which is followed shortly after by the de-orbit burn. During the de-orbit burn, <em>Freedom<\/em> fired its four forward-facing Draco engines, which are located around the docking port at the nose of the capsule, and performed the longest burn of the mission. Following the completion of the burn, the docking port nosecone was closed in preparation for re-entry.<\/p>\n<p>During re-entry, the mission entered a communications blackout period. At this time, the intense heat and plasma that forms around the vehicle due to Dragon\u2019s immense speed prevented ground stations from exchanging communications with the crew and the spacecraft. This phenomenon is not unique to Dragon, however, as every crewed spacecraft in history that has returned to Earth has experienced some sort of blackout period during re-entry.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-87204\" class=\"size-full wp-image-87204\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-scaled.jpg\" alt=\"\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-scaled.jpg 2560w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-350x233.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-525x350.jpg 525w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-768x512.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-1920x1280.jpg 1920w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-1170x780.jpg 1170w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-585x390.jpg 585w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/07\/52034684153_49a78f310f_o-263x175.jpg 263w\" sizes=\"(max-width: 2560px) 100vw, 2560px\"><\/p>\n<p id=\"caption-attachment-87204\" class=\"wp-caption-text\">Falcon 9 (B1067-4) launches Crew-4.

Once <em>Freedom<\/em> has detected that it is at a certain altitude and velocity, it deploys its two drogue parachutes and slows down to ~350 miles per hour.<\/p>\n<p>The parachutes partially deploy at first before fully inflating in a process known as reefing. Reefing allows parachutes to open in a slower and more-controlled manner to avoid higher loads on the vehicle and crew during descent.<\/p>\n<p>Shortly after full drogue inflation, the drogue parachutes are cut and the main parachutes are deployed. The four main parachutes also reef to ease the loads on the vehicle and crew.<\/p>\n<p>The main parachutes slow the vehicle down from ~350 miles per hour to around ~15 miles per hour for splashdown. After descending under the main parachutes for several minutes, Crew-4 splashed down in the Atlantic Ocean east of Jacksonville, Florida. This site was selected over alternatives in the Gulf of Mexico or elsewhere in the Atlantic Ocean based on weather conditions at the time of splashdown.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-81750\" class=\"size-full wp-image-81750\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-scaled.jpg\" alt=\"\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-scaled.jpg 2560w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-350x233.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-525x350.jpg 525w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-768x512.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-1920x1280.jpg 1920w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-1170x780.jpg 1170w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-585x390.jpg 585w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2021\/11\/51494577685_15262950de_o-1-263x175.jpg 263w\" sizes=\"(max-width: 2560px) 100vw, 2560px\"><\/p>\n<p id=\"caption-attachment-81750\" class=\"wp-caption-text\">Splashdown of Crew Dragon Resilience during the private Inspiration4 mission in September 2021.
