Three Chinese astronauts aboard the orbiting outpost will open hatches and begin unpacking equipment, while internal valves open to flow propellants from the cargo ship into storage tanks on the station\u2019s Tianhe core module.<\/p>\n<p>The Tianzhou 6 spacecraft debuts an upgraded internal design, with 20% more payload capacity to carry up to 7.4 metric tons (16,300 pounds) of cargo. The cargo ship also carries about 1,750 kilograms (3,858 pounds) of propellant to support the space station, about 700 kilograms (1,543 pounds) of which will refill tanks on the Tiangong space station.<\/p>\n<p>The modifications to Tianzhou 6 are primarily inside the spacecraft to improve the packing efficiency of the pressurized cargo module. The spacecraft weighed nearly 30,000 pounds (about 13.5 metric tons) at launch, the same as previous Tianzhou missions.<\/p>\n<p>The resupply mission lifted off on a 174-foot-tall (53-meter) Long March 7 rocket from the Wenchang launch base on Hainan Island, China\u2019s newest and southernmost spaceport. The exact liftoff time of 9:22:51 a.m. EDT (1322:51 UTC) Wednesday was set to coincide with the moment Earth\u2019s rotation carried the launch pad under the flight path of the Tiangong space station, enabling a quick rendezvous and docking.<\/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=1656289369156714498&amp;lang=en&amp;origin=https%3A%2F%2Fspaceflightnow.com%2F2023%2F05%2F10%2Flong-march-7-tianzhou-6-launch%2F&amp;sessionId=9e920c7a7f2868219f235935d32ab58db047b91b&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"1656289369156714498\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-twitter-extracted-i1782462463729343557=\"true\">\n<p dir=\"ltr\" lang=\"en\">China\u2019s Tianzhou 6 resupply ship lifted off aboard a Long March 7 rocket from Hainan Island at 9:22am EDT (1322 UTC) in pursuit of the Tiangong space station. https:\/\/t.co\/mDC54hmwOZ pic.twitter.com\/PN3BQLzTP8<\/p>\n<p>\u2014 Spaceflight Now (@SpaceflightNow) May 10, 2023<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>The Tiangong space station, with its three-person crew, orbits more than 230 miles (370 kilometers) above Earth at an inclination of 41.5 degrees to the equator. Tianzhou 6 is the sixth flight of China\u2019s resupply ship, which is similar in purpose to the SpaceX Dragon, Northrop Grumman Cygnus, and Russian Progress cargo ships that regularly deliver equipment to the International Space Station.<\/p>\n<p>It\u2019s the fifth Tianzhou mission to the Tiangong space station, following a test flight to China\u2019s now-decommissioned Tiangong 2 space lab, a testbed used before construction of the larger Tiangong complex. Tianzhou means \u201cheavenly ship\u201d in English.<\/p>\n<p>The Long March 7 rocket ignited six booster engines to climb off the launch pad at Wenchang with 1.6 million pounds of thrust. An on-board guidance computer commanded the rocket to head southeast over the South China Sea, lining up with the Tiangong space station\u2019s orbit.<\/p>\n<p>The Long March 7 is a two-stage rocket augmented with four strap-on boosters. The rocket consumed 45,000 gallons, or 170 cubic meters, of kerosene fuel in combination with cryogenic liquid oxygen during the 10-minute ascent into orbit.<\/p>\n<figure id=\"attachment_27386\" aria-describedby=\"caption-attachment-27386\" style=\"width: 600px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-27386 size-full\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/09\/1709221851203764718.jpg\" alt=\"\" width=\"600\" height=\"337\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/09\/1709221851203764718.jpg 600w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/09\/1709221851203764718-300x169.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\"><figcaption id=\"caption-attachment-27386\" class=\"wp-caption-text\">Artist\u2019s concept of the a Tianzhou cargo spacecraft.
