The mission marks SpaceX\u2019s fourth launch in 10 days, and SpaceX\u2019s 31st launch of 2022, tying the record number of Falcon 9 missions in a calendar year.<\/p>\n<p>The Falcon 9 booster landed on SpaceX\u2019s drone ship parked downrange in the Atlantic Ocean northeast of Cape Canaveral.<\/p>\n<p>The rocket headed northeast from Cape Canaveral Space Force Station, aiming to deliver the flat-packed broadband relay stations to an orbit ranging between 144 miles and 210 miles in altitude (232-by-338 kilometers). Deployment of the 53 flat-packed satellites from the Falcon 9\u2019s upper stage occurred about 15 minutes after liftoff.<\/p>\n<p>With Sunday\u2019s mission, designated Starlink 4-22, SpaceX has launched 2,858 Starlink internet satellites, including prototypes and test units no longer in service. The launch Thursday marked the 51st SpaceX mission primarily dedicated to hauling Starlink internet satellites into orbit.<\/p>\n<p>Stationed inside a firing room at a launch control center just south of Cape Canaveral Space Force Station, SpaceX\u2019s launch team began loading super-chilled, densified kerosene and liquid oxygen propellants into the 229-foot-tall (70-meter) Falcon 9 vehicle at T-minus 35 minutes.<\/p>\n<p>Helium pressurant also flowed into the rocket in the last half-hour of the countdown. In the final seven minutes before liftoff, the Falcon 9\u2019s Merlin main engines were thermally conditioned for flight through a procedure known as \u201cchilldown.\u201d&nbsp;The Falcon 9\u2019s guidance and range safety systems were also configured for launch.<\/p>\n<p>After liftoff, the Falcon 9 rocket vectored its 1.7 million pounds of thrust \u2014 produced by nine Merlin engines \u2014 to steer northeast over the Atlantic Ocean.<\/p>\n<p>The rocket exceeded the speed of sound in about one minute, then shut down its nine main engines two-and-a-half minutes after liftoff. The booster stage released from the Falcon 9\u2019s upper stage, then fired pulses from cold gas control thrusters and extended titanium grid fins to help steer the vehicle back into the atmosphere.<\/p>\n<p>Two braking burns slowed the rocket for landing on the drone ship \u201cJust Read the Instructions\u201d around 400 miles (650 kilometers) downrange approximately eight-and-a-half minutes after liftoff.<\/p>\n<figure id=\"attachment_56932\" aria-describedby=\"caption-attachment-56932\" style=\"width: 1200px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-56932\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/05\/starlink-data.jpg\" alt=\"\" width=\"1200\" height=\"675\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/05\/starlink-data.jpg 1200w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/05\/starlink-data-300x169.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/05\/starlink-data-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2022\/05\/starlink-data-768x432.jpg 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\"><figcaption id=\"caption-attachment-56932\" class=\"wp-caption-text\">Credit: Spaceflight Now<\/figcaption><\/figure>\n<p>The booster \u2014 tail number B1051 \u2014 that flew Sunday is one of the oldest in SpaceX\u2019s fleet of reusable rockets. It debuted in March 2019 with the first unpiloted test flight of SpaceX\u2019s Crew Dragon spacecraft. Since then, the booster has launched Canada\u2019s Radarsat Constellation Mission, SiriusXM\u2019s SXM 7 radio broadcasting satellite, and nine Starlink missions.<\/p>\n<p>With Sunday\u2019s mission, B1051 became the third booster in SpaceX\u2019s inventory to reach the 13-flight milestone. SpaceX has certified Falcon 9 boosters for at least 15 missions, an extension from the original certification of 10 flights.<\/p>\n<p>Landing of the first stage on Sunday\u2019s mission occurred moments after the Falcon 9\u2019s second stage engine cut off to deliver the Starlink satellites into orbit. Separation of the 53 spacecraft, built by SpaceX in Redmond, Washington, was confirmed at T+plus 15 minutes, 28 seconds.<\/p>\n<p>Retention rods released from the Starlink payload stack, allowing the flat-packed satellites to fly free from the Falcon 9\u2019s upper stage in orbit.&nbsp;The 53 spacecraft will unfurl solar arrays and run through automated activation steps, then use krypton-fueled ion engines to maneuver into their operational orbit.<\/p>\n<p>The Falcon 9\u2019s guidance computer aimed to deploy the satellites into an elliptical orbit at an orbital inclination of 53.2 degrees to the equator. The satellites will use on-board propulsion to do the rest of the work to reach a circular orbit 335 miles (540 kilometers) above Earth.<\/p>\n<p>The Starlink satellites will fly in one of five orbital \u201cshells\u201d at different inclinations for SpaceX\u2019s global internet network. After reaching their operational orbit, the satellites will&nbsp;enter commercial service and begin beaming broadband signals to consumers, who can purchase Starlink service and connect to the network with a SpaceX-supplied ground terminal.<\/p>\n<p><strong>ROCKET:<\/strong>&nbsp;Falcon 9 (B1051.13)<\/p>\n<p><strong>PAYLOAD: <\/strong>53&nbsp;Starlink satellites (Starlink 4-22)<\/p>\n<p><strong>LAUNCH SITE: <\/strong>SLC-40, Cape Canaveral Space Force Station, Florida<\/p>\n<p><strong>LAUNCH DATE:&nbsp;<\/strong>July 17,&nbsp;2022<\/p>\n<p><strong>LAUNCH TIME:<\/strong>&nbsp;10:20:00 a.m. EDT (1420:00 GMT)<\/p>\n<p><strong>WEATHER FORECAST:<\/strong>&nbsp;50% chance&nbsp;of acceptable weather; Low risk of upper level winds; Low risk of unfavorable conditions for booster recovery<\/p>\n<p><strong>BOOSTER RECOVERY:&nbsp;<\/strong>\u201cJust Read the Instructions\u201d drone ship east of Charleston, South Carolina<\/p>\n<p><strong>LAUNCH AZIMUTH: <\/strong>Northeast<\/p>\n<p><strong>TARGET ORBIT: <\/strong>144 miles by 210 miles (232 kilometers by 338 kilometers), 53.2 degrees inclination<\/p>\n<p><strong>LAUNCH TIMELINE:<\/strong><\/p>\n<ul>\n<li>T+00:00: Liftoff<\/li>\n<li>T+01:12: Maximum aerodynamic pressure (Max-Q)<\/li>\n<li>T+02:28:&nbsp;First stage main engine cutoff (MECO)<\/li>\n<li>T+02:32: Stage separation<\/li>\n<li>T+02:39: Second stage engine ignition<\/li>\n<li>T+02:43: Fairing jettison<\/li>\n<li>T+06:50: First stage entry burn ignition (three engines)<\/li>\n<li>T+07:09: First stage entry burn cutoff<\/li>\n<li>T+08:26: First stage landing burn ignition (one engine)<\/li>\n<li>T+08:47: Second stage engine cutoff (SECO 1)<\/li>\n<li>T+08:48: First stage landing<\/li>\n<li>T+15:28: Starlink satellite separation<\/li>\n<\/ul>\n<p><strong>MISSION STATS:<\/strong><\/p>\n<ul>\n<li>165th launch of a Falcon 9 rocket since 2010<\/li>\n<li>173rd launch of Falcon rocket family since 2006<\/li>\n<li>13th launch of Falcon 9 booster B1051<\/li>\n<li>143rd Falcon 9 launch from Florida\u2019s Space Coast<\/li>\n<li>92nd Falcon 9 launch from pad 40<\/li>\n<li>147th launch overall from pad 40<\/li>\n<li>107th flight of a reused Falcon 9 booster<\/li>\n<li>51st dedicated Falcon 9 launch with Starlink satellites<\/li>\n<li>31st Falcon 9 launch of 2022<\/li>\n<li>31st launch by SpaceX in 2022<\/li>\n<li>31st orbital launch based out of Cape Canaveral in 2022<\/li>\n<\/ul>\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>Live coverage of the countdown and launch of a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
