The Starship has nearly 10 times the payload lift capability of a Falcon 9 rocket, with greater volume for satellites, too.<\/p>\n<p>SpaceX could attempt to launch the huge Starship rocket into space for the first time as soon next month from South Texas. But the program has faced developmental delays, and SpaceX decided to build miniature versions of the upgraded Starship-compatible Version 2 Starlink satellites to fly on Falcon 9 rockets.<\/p>\n<p>\u201cThe V2 satellites launched on Falcon 9 are a bit smaller, so we affectionately refer to them as \u2018V2 Mini\u2019 satellites,\u201d SpaceX said. \u201cBut don\u2019t let the name fool you, a V2 Mini satellite has four times the capacity for serving users compared to its earlier counterparts.\u201d<\/p>\n<p>The Starlink V2 satellites will be capable of transmitting signals directly to cell phones, a step forward in connectivity from space that other companies are also pursuing. The V2 Mini satellites have more powerful phased array antennas than older Starlink satellites, and introduce E-band for backhaul links with gateway stations.<\/p>\n<p>\u201cThis means Starlink can provide more bandwidth with increased reliability and connect millions of more people around the world with high-speed internet,\u201d SpaceX said.<\/p>\n<figure id=\"attachment_60964\" aria-describedby=\"caption-attachment-60964\" style=\"width: 1200px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-60964\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlink6-1launch.jpg\" alt=\"\" width=\"1200\" height=\"800\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlink6-1launch.jpg 1200w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlink6-1launch-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlink6-1launch-678x452.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlink6-1launch-768x512.jpg 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\"><figcaption id=\"caption-attachment-60964\" class=\"wp-caption-text\">A Falcon 9 rocket climbs away from pad 40 at Cape Canaveral Space Force Station with the first 21 Starlink V2 Mini satellites. Credit: SpaceX<\/figcaption><\/figure>\n<p>Unlike most of SpaceX\u2019s Starlink missions, which place their satellites in lower-altitude transfer orbits, the Starlink 6-1 mission Monday injected the 21 V2 Mini satellites into an orbit closer to their final operating altitude, minimizing the time needed for the spacecraft to use their own propulsion to maneuver into their final orbital positions.<\/p>\n<p>The Starlink V2 Mini satellites also carry an argon-fueled electrical propulsion system using Hall thrusters for on-orbit maneuvering. The new propulsion system has 2.4 times the thrust and 1.5 times the specific impulse, or fuel efficiency, of the krypton-fueled ion thrusters on the first generation of Starlink satellites.<\/p>\n<p>The argon Hall thrusters were developed by SpaceX engineers, the company said, and are the first of their kind to operate in space. The electric propulsion system is highly efficient, but low thrust, generating an impulse by accelerating argon gas through the engine using electricity.<\/p>\n<p>SpaceX says the argon thrusters can put out about 170 millinewtons, or about 0.04 pounds, of thrust. That\u2019s less than the weight of a AA battery. The entire thruster unit weighs less than 5 pounds, or 2.1 kilograms<\/p>\n<p>Argon gas is cheaper than the krypton fuel used on the first generation of Starlink satellites. Before the Starlink network, most electric thrusters for in-space propulsion relied on more expensive xenon gas.<\/p>\n<p>Each Starlink V2 Mini satellite weighs about 1,760 pounds (800 kilograms) at launch, nearly three times heavier than the older Starlink satellites. The are also bigger in size, with a spacecraft body more than 13 feet (4.1 meters) wide, filling more of the Falcon 9 rocket\u2019s payload fairing during launch, according to regulatory filings with the Federal Communications Commission.<\/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=1630351153253830658&amp;lang=en&amp;origin=https%3A%2F%2Fspaceflightnow.com%2F2023%2F02%2F27%2Ffalcon-9-starlink-6-1-live-coverage%2F&amp;sessionId=8de7c11e6acf9fa348c906c37bb6dac2d8977c6b&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"1630351153253830658\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-twitter-extracted-i178246838160586307=\"true\">\n<p dir=\"ltr\" lang=\"en\">Liftoff of SpaceX\u2019s Falcon 9 rocket from Cape Canaveral, launching a new generation of broadband connectivity for SpaceX\u2019s Starlink internet network. https:\/\/t.co\/iv8zvdJHak pic.twitter.com\/Wg34oMqnRn<\/p>\n<p>\u2014 Spaceflight Now (@SpaceflightNow) February 27, 2023<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>Once deployed from the Falcon 9 rocket, the Starlink V2 Mini satellites will unfurl two solar array wings to a span of about 100 feet (30 meters). The original Starlink satellites each have a single solar array wing, with each spacecraft measuring about 36 feet (11 meters) end-to-end once the solar panel is extended.<\/p>\n<p>The enhancements give the Starlink V2 Mini satellites a total surface area of 1,248 square feet, or 116 square meters, more than four times that of a Starlink V1.5 satellite.<\/p>\n<p>The full-size Starlink V2 satellites, which will launch on the Starship rocket, will have more than double the surface area of a Starlink V2 Mini spacecraft, according to SpaceX filings with the FCC.<\/p>\n<p>SpaceX added dark paint and visors to earlier Starlink satellites to reduce their reflectivity. The mitigations were installed on Starlink satellites after the first batch of spacecraft launched in 2019 were brighter than expected, raising concerns from scientists that thousands of the satellites could interfere with ground-based astronomy.<\/p>\n<p>But the dark paint was not as effective as hoped, and SpaceX removed the visors from later Starlink satellites to allow them to use laser inter-satellite communications links. Ground teams also changed the orientation of the Starlink satellites to minimize reflections of sunlight that could reach the ground at twilight.<\/p>\n<p>Later Starlink satellites used dielectric mirror film on spacecraft surfaces, which directs reflected sunlight away from Earth. The new generation of Starlink satellites include a combination of mirrors and a new type of low-reflectivity paint, and the solar arrays are designed to adjust their pointing when the spacecraft fly over regions of Earth at dawn and dusk.<\/p>\n<p>\u201cSo, while our V2 Mini satellites are larger than earlier versions, we\u2019re still expecting them to be as dark or darker once the full range of mitigations are implemented and the satellites reach their operational orbit,\u201d SpaceX said in a document describing the new satellite design.<\/p>\n<p>But the new larger satellites may still be \u201csomewhat bright\u201d immediately after launch, when they\u2019re flying close together in a so-called \u201ctrain\u201d formation, the company said. SpaceX said measurements, modeling, and analysis show the brightness mitigations will be effective in reducing the V2 Mini satellites\u2019 reflectivity, but engineers won\u2019t know for sure until scientists observe the satellites after launch.<\/p>\n<p>\u201cWhat we learn from early observations will help us improve and refine mitigations,\u201d SpaceX said.<\/p>\n<p>\u201cAs our track record demonstrates, SpaceX will work tirelessly to refine design\/manufacturing\/materials and, but as our track operational mitigations and continue to work with astronomers toward reducing the brightness of our satellites,\u201d SpaceX said.<\/p>\n<p>The company said it will make the mirror film and dark paint material available at cost to other operators deploying large constellations of satellites in orbit.<\/p>\n<figure id=\"attachment_60958\" aria-describedby=\"caption-attachment-60958\" style=\"width: 1200px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-60958\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlinkv2mini-1.jpg\" alt=\"\" width=\"1200\" height=\"673\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlinkv2mini-1.jpg 1200w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlinkv2mini-1-300x168.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlinkv2mini-1-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2023\/02\/20230227starlinkv2mini-1-768x431.jpg 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\"><figcaption id=\"caption-attachment-60958\" class=\"wp-caption-text\">A side-by-side comparison of the Starlink V1.5 and the Starlink V2 Mini satellites.

Collisions in low Earth orbit could generate thousands of small fragments that would exacerbate the orbital debris problem.<\/p>\n<p>The new Starlink satellite design is part of SpaceX\u2019s second-generation Starlink constellation, called Gen2.<\/p>\n<p>The FCC granted SpaceX approval Dec. 1 to launch up to 7,500 of its planned 29,988-spacecraft Starlink Gen2 constellation, which is spread out into slightly different orbits than the original Starlink fleet. The regulatory agency deferred a decision on the remaining satellites SpaceX proposed for Gen2.<\/p>\n<p>SpaceX began launching older-generation Starlink V1.5 satellites into the Gen2 constellation on Dec. 28. The launch Monday was the first to deploy the brand new spacecraft design.<\/p>\n<p>\u201cWith the recent authorization of our second-generation network, or \u2018Gen2,\u2019 SpaceX will provide even faster speeds to more users,\u201d SpaceX said.<\/p>\n<p>The FCC previously authorized SpaceX to launch and operate up to 12,000 Starlink satellites, including roughly 4,400 first-generation Ka-band and Ku-band Starlink spacecraft that SpaceX has been launching since 2019.<\/p>\n<p>The Gen2 satellites could improve Starlink coverage over lower latitude regions, and help alleviate pressure on the network from growing consumer uptake. SpaceX says the network has more than 1 million active subscribers, mostly households in areas where conventional fiber connectivity is unavailable, unreliable, or expensive.<\/p>\n<p>The Starlink spacecraft beam broadband internet signals to consumers around the world, connectivity that is now available on all seven continents with testing underway at a research station in Antarctica.<\/p>\n<p><iframe id=\"twitter-widget-1\" 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-1&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=1630352428179550208&amp;lang=en&amp;origin=https%3A%2F%2Fspaceflightnow.com%2F2023%2F02%2F27%2Ffalcon-9-starlink-6-1-live-coverage%2F&amp;sessionId=8de7c11e6acf9fa348c906c37bb6dac2d8977c6b&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"1630352428179550208\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-twitter-extracted-i178246838160586307=\"true\">\n<p dir=\"ltr\" lang=\"en\">SpaceX\u2019s payload fairing jettisoned about three minutes after launch from Florida.<\/p>\n<p>This rare view from the top of the Starlink payload stack shows the nose shroud falling away from the Falcon 9 rocket.<\/p>\n<p>The fairing halves will be recovered and reused.https:\/\/t.co\/iv8zvdJHak pic.twitter.com\/Pm1WRHFI4F<\/p>\n<p>\u2014 Spaceflight Now (@SpaceflightNow) February 27, 2023<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>With the 21 satellites launched Monday from Florida, SpaceX passed the milestone of 4,000 Starlink spacecraft launched to date, including test vehicles and prototypes no longer in service and already removed from orbit.<\/p>\n<p>SpaceX will continue launching more Starlink V1.5 satellites for at least some time.

The booster stage separated 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><iframe id=\"twitter-widget-2\" 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-2&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=1630354846015471618&amp;lang=en&amp;origin=https%3A%2F%2Fspaceflightnow.com%2F2023%2F02%2F27%2Ffalcon-9-starlink-6-1-live-coverage%2F&amp;sessionId=8de7c11e6acf9fa348c906c37bb6dac2d8977c6b&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"1630354846015471618\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-twitter-extracted-i178246838160586307=\"true\">\n<p dir=\"ltr\" lang=\"en\">A twilight touchdown on SpaceX\u2019s drone ship northeast of the Bahamas marked the 100th consecutive successful landing of a Falcon booster.<\/p>\n<p>Falcon 9\u2019s upper stage is now in a parking orbit with 21 upgraded Starlink satellites.https:\/\/t.co\/iv8zvdJHak pic.twitter.com\/m6ey1AW1Eo<\/p>\n<p>\u2014 Spaceflight Now (@SpaceflightNow) February 27, 2023<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>Two braking burns slowedthe rocket for landing on the drone ship \u201cA Shortfall of Gravitas\u201d around 400 miles (640 kilometers) downrange approximately eight-and-a-half minutes after liftoff.

After separating from the rocket, the 21 Starlink spacecraft will extend their solar arrays and run through automated activation steps, then use their ion engines to maneuver into their operational orbit more than 300 miles (500 kilometers) above Earth.<\/p>\n<p><iframe id=\"twitter-widget-3\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: absolute;
