The launch occurred at 1:13 PM EST (18:13 UTC) on Thursday, February 3, from the historic Launch Complex 39A at NASA\u2019s Kennedy Space Center in Florida.<\/p>\n<p>In addition to reusing a Falcon 9 first stage, both fairing halves were reused from previous missions. One half flew on its sixth mission, setting a new record for SpaceX.<\/p>\n<\/p>\n<p>The 45th Weather Squadron at Patrick Space Force Base forecasted an 80% chance of favorable weather for launch with a moderate risk of violating weather criteria in the booster recovery area. If the launch was scrubbed for any reason, a backup launch opportunity existed on Friday, February 4, &nbsp;with a 70% chance of acceptable weather forecasted. This window was not needed, as the launch went on time on Thursday.<\/p>\n<p>This launch marks the sixth mission of the year for SpaceX, having already launched two Starlink missions, Transporter-3,&nbsp; CSG-2, and NROL-87.<\/p>\n<p>As the Falcon 9 lifted off, it headed towards the southeast corridor from Cape Canaveral, hugging the coast of the Bahamas as it performed a dogleg maneuver to avoid flying over populated areas. This maneuver is the reason why SpaceX launched fewer satellites on this mission, compared to other launches from Florida, which launched 53 Starlink satellites.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" aria-describedby=\"caption-attachment-83592\" class=\"wp-image-83592 size-full\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-scaled.jpg\" alt=\"\" width=\"2560\" height=\"1635\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-scaled.jpg 2560w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-350x224.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-548x350.jpg 548w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-768x490.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-1920x1226.jpg 1920w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/julia-1170x747.jpg 1170w\" sizes=\"(max-width: 2560px) 100vw, 2560px\"><\/p>\n<p id=\"caption-attachment-83592\" class=\"wp-caption-text\">A Shortfall of Gravitas arrives at Port Canaveral for the first time in July 2021.

This mission, named Starlink 4-7, launched satellites to the fourth shell. SpaceX is actively scheduling and launching to fill up the fourth shell of the mega-constellation, which when complete, will increase the capacity and reduce the latency for customers located between 52 degrees North and 52 degrees South latitude.<\/p>\n<p><b>Launch Timeline<\/b><\/p>\n<p>At T-38 minutes, the Launch Director gave a GO for propellant loading. At T-35 minutes, SpaceX began loading sub-cooled RP-1 onto both the first stage and the second stages as well as super-chilled LOX (Liquid Oxygen) onto the first stage.<\/p>\n<p>SpaceX, unlike any other company in the industry, uses RP-1 which is cooled to -7 degrees Celsius and the LOX is cooled to -205 degrees Celsius. Using supercooled propellants increases the performance of Falcon 9 \u2014 something that is essential for reuse \u2014since low temperatures increase the density of propellants.<\/p>\n<p>Just before T-20 minutes, the second stage RP-1 load was completed, which was marked by a large vent from the T\/E (Transporter Erector). This vent was followed by the purging of the T\/E lines ahead of the start of LOX load to the second stage at T-16 minutes.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-83614\" class=\"wp-image-83614 size-full\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak.jpg\" alt=\"\" width=\"1403\" height=\"934\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak.jpg 1403w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak-350x233.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak-526x350.jpg 526w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak-768x511.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak-1170x779.jpg 1170w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak-585x390.jpg 585w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/01\/streak-263x175.jpg 263w\" sizes=\"(max-width: 1403px) 100vw, 1403px\"><\/p>\n<p id=\"caption-attachment-83614\" class=\"wp-caption-text\">Falcon 9 streaks southeast from Cape Canaveral in January 2022 carrying the Starlink 4-6 group to orbit. (Credit: Brady Kenniston for NSF)<\/p>\n<p>At T-7 minutes, the Falcon 9 allowed a small amount of liquid oxygen to enter the nine Merlin 1D engines on the first stage. This process cooled the engines slowly so they do not get damaged from the thermal shock when super chilled LOX starts to flow through them at full volume during engine ignition.<\/p>\n<p>At T-1 minute, the Falcon 9 entered start up and began pressurizing its tanks for flight. At this point, Falcon 9\u2019s onboard computers became fully in charge of its countdown, and all technical aborts from this point forward would have been handled autonomously and not by the ground operators.<\/p>\n<p>At T-45 seconds, the Launch Director verified that all positions were go for launch. At T-3 seconds, the F9\u2019s flight computer commanded the ignition of the 9 Merlin 1D engines on the first stage. The ignition happens in pairs within milliseconds of each other to reduce startup transients and loads on the vehicle.<\/p>\n<p>Once the computers ensured all systems are nominal, they command the hydraulic clamps at the base of the vehicle to release, letting the Falcon 9 lift off from the pad.<\/p>\n<p>B1061 burned for approximately two and a half minutes before shutting down \u2014 once again in a staggered formation to reduce loads on the vehicle.<\/p>\n<p>The first stage separated from the second stage using pneumatic pushers, followed by ignition of the second stage\u2019s single vacuum optimized Merlin engine seconds later.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-83932\" class=\"wp-image-83932 size-full\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-scaled.jpeg\" alt=\"\" width=\"2560\" height=\"1440\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-scaled.jpeg 2560w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-350x197.jpeg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-622x350.jpeg 622w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-768x432.jpeg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-1920x1080.jpeg 1920w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2022\/02\/AA1BD51E-CD03-481D-97AC-130D77A839F7-1170x658.jpeg 1170w\" sizes=\"(max-width: 2560px) 100vw, 2560px\"><\/p>\n<p id=\"caption-attachment-83932\" class=\"wp-caption-text\">Falcon 9 flies southeast from Cape Canaveral on the Starlink Group 4-5 mission in January 2022.
