The company began its official webcast on X at 9:56 a.m. ET and has posted a detailed post\u2011liftoff timeline; boosters are expected to touch down at Cape Canaveral roughly eight minutes after liftoff, producing audible sonic booms. Weather forecasts from the U.S. Space Force&#8217;s 45th Weather Squadron show a 90% chance of favorable conditions for the window.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>Scheduled liftoff: 10:13 a.m. ET on April 28, 2026, from Launch Complex 39A at Kennedy Space Center.<\/li>\n<li>Booster recovery: Side boosters will return to Cape Canaveral Landing Zones 2 and 40, with landing burns beginning around T+7:41 and touchdown near T+7:58\u2013T+8:13.<\/li>\n<li>Mission timeline: Key in\u2011flight events include Max Q at 00:01:09, fairing separation at 00:04:17, and first SECO at 00:08:13; ViaSat\u20113 F3 deployment is slated for 04:57:31.<\/li>\n<li>ViaSat\u20113 constellation: F1 launched May 2023 (Falcon Heavy), F2 launched Nov. 2025 (ULA Atlas V); F3 is the most powerful of the trio and aims to add >1 Tbps capacity to the Asia\u2011Pacific region.<\/li>\n<li>Vehicle reuse: One side booster flew SDA\u20110A, SARah\u20112, Transporter\u201111 and 18 Starlink missions; the other flew GOES\u2011U in June 2024.<\/li>\n<li>Countdown: Propellant loading and engine chill follow a tightly scripted timeline beginning roughly 53 minutes before liftoff; a failure to meet those milestones would delay the attempt.<\/li>\n<li>Local readiness: Brevard County Emergency Management activated launch operations support ahead of the event to coordinate public safety and road closures.<\/li>\n<\/ul>\n<h2>Background<\/h2>\n<p>The Falcon Heavy pairs three Falcon 9\u2011class cores to deliver heavier payloads or higher mass to distant orbits. SpaceX routinely recovers side boosters for reuse; this mission will land those boosters at Cape Canaveral Landing Zones 2 and 40 rather than side\u2011by\u2011side, a change in recovery pattern relative to some previous Falcon Heavy flights. Reuse of cores keeps launch costs lower and supports a higher flight cadence for commercial and government customers.<\/p>\n<p>The payload, ViaSat\u20113 F3, is the third satellite in Viasat\u2019s Ka\u2011band high\u2011capacity constellation intended to serve global broadband demand. VS\u20113 F1 was launched in May 2023 on a Falcon Heavy and serves airline connectivity customers; VS\u20113 F2 launched in November 2025 on a ULA Atlas V and carries roughly twice the power of F1. Viasat says F3 will be the most powerful of the three and is expected to add greater than 1 Tbps of throughput concentrated on the Asia\u2011Pacific region.<\/p>\n<h2>Main Event<\/h2>\n<p>SpaceX\u2019s live coverage began at 9:56 a.m. ET on X (formerly Twitter), with commentators and countdown telemetry visible online. The company\u2019s prelaunch sequence follows a precise cadence: at T\u201153:00 the launch director verifies go for propellant load; RP\u20111 and LOX loading windows begin between T\u201150:00 and T\u201135:00; and engine chill for the Falcon Heavy begins at T\u201107:00. At T\u201100:59 the flight computer starts final prelaunch checks and the launch director provides the final go\/no\u2011go at T\u201100:45.<\/p>\n<p>After liftoff, the mission timeline SpaceX published sets out a dense sequence of events. Max Q (peak aerodynamic stress) is expected at 00:01:09, side booster engine cutoff (BECO) at 00:02:21 followed by separation at 00:02:25 and a flip maneuver at 00:02:30. The side boosters should perform boostback burns roughly between 00:02:41 and 00:03:47, with first stage main engine cutoff (MECO) at 00:03:50 and stage separation at 00:03:54.<\/p>\n<p>Recovery and upper\u2011stage operations continue minutes and hours later: fairing separation is slated for 00:04:17, side booster entry and landing burns occur between 00:06:28 and about 00:07:58 with touchdown at Cape Canaveral near T+7:58. The second stage resumes multiple burns\u2014SES\u20112 at 00:26:05 with SECO\u20112 at 00:27:33, and a third sequence beginning at 04:47:47\u2014culminating in the targeted ViaSat\u20113 F3 deployment at 04:57:31.<\/p>\n<h2>Analysis &#038; Implications<\/h2>\n<p>Operationally, a successful Falcon Heavy launch and booster recovery would reinforce SpaceX\u2019s reuse model for heavy\u2011lift missions, demonstrating that previously flown side cores (including ones with long service histories) can support high\u2011value national and commercial payloads. The differing recovery profile\u2014separate LZs instead of side\u2011by\u2011side landings\u2014reflects mission\u2011specific trajectory and downrange constraints rather than a permanent change to landing practice.<\/p>\n<p>For Viasat, F3\u2019s addition promises a sizeable jump in throughput for the Asia\u2011Pacific market. Adding more than 1 Tbps of capacity would help close gaps in maritime, airborne and terrestrial broadband coverage, but the practical user benefit will depend on ground gateway upgrades, regulatory clearances in regional markets and commercial agreements with service providers.<\/p>\n<p>Local economic and safety considerations are tangible. Sonic booms from booster re\u2011entries and landings can produce disturbances for coastal communities; Brevard County\u2019s activation of emergency\u2011operations support reflects standard coordination to manage road closures, public notifications and potential search and rescue assets. Insurance, frequency coordination and orbital\u2011debris assessments also factor into the broader risk calculus for high\u2011throughput GEO satellites.<\/p>\n<h2>Comparison &#038; Data<\/h2>\n<figure>\n<table>\n<thead>\n<tr>\n<th>Satellite<\/th>\n<th>Launch Vehicle<\/th>\n<th>Launch Date<\/th>\n<th>Relative Power\/Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>VS\u20113 F1<\/td>\n<td>Falcon Heavy<\/td>\n<td>May 2023<\/td>\n<td>Provides airline in\u2011flight internet; baseline of constellation<\/td>\n<\/tr>\n<tr>\n<td>VS\u20113 F2<\/td>\n<td>ULA Atlas V<\/td>\n<td>Nov. 2025<\/td>\n<td>~2\u00d7 power of F1<\/td>\n<\/tr>\n<tr>\n<td>VS\u20113 F3<\/td>\n<td>Falcon Heavy<\/td>\n<td>Apr. 28, 2026 (this mission)<\/td>\n<td>Most powerful; adds >1 Tbps to Asia\u2011Pacific<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>The table shows the fleet\u2019s launch history and relative on\u2011orbit capability.

BECO and MECO are engine cutoffs for boosters and the first stage, marking stage transition points; SES and SECO refer to second\u2011stage engine starts and cutoffs during coast\u2011burn sequences. Fairing separation jettisons the payload shroud once aerodynamic pressure is low. Boostback, entry and landing burns are the phases by which reusable boosters return to a controlled landing at sea\u2011based droneships or onshore landing zones.<\/p>\n<\/details>\n<\/aside>\n<h2>Unconfirmed<\/h2>\n<ul>\n<li>Any last\u2011minute changes to landing zone assignments due to wind or range constraints would be confirmed only in real time by SpaceX; such adjustments have occurred on past missions but are not indicated in prelaunch materials.<\/li>\n<li>Precise in\u2011orbit commissioning timeline for ViaSat\u20113 F3 (gateway activation and customer rollouts) has not been publicly dated beyond generic post\u2011deployment testing windows.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>Today\u2019s Falcon Heavy launch from Kennedy Space Center is a high\u2011visibility commercial mission that pairs SpaceX\u2019s heavy\u2011lift and booster\u2011reuse capabilities with Viasat\u2019s push to expand global broadband capacity. The mission follows a tightly choreographed sequence of fueling, engine chill and staged burns; any deviation in those prelaunch milestones would push the attempt to a later slot.<\/p>\n<p>If successful, the flight will complete the ViaSat\u20113 trio in GEO and materially increase capacity over the Asia\u2011Pacific region, while reinforcing SpaceX\u2019s model of reusing previously flown cores even on premium payloads. Residents near Cape Canaveral should expect sonic booms near booster landing times and follow local public\u2011safety guidance issued by Brevard County.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.floridatoday.com\/story\/tech\/science\/space\/spacex\/2026\/04\/28\/spacex-falcon-heavy-launch-from-florida-kennedy-space-center-what-to-know-before-sonic-booms--live\/89820216007\/\" target=\"_blank\" rel=\"noopener\">Florida Today (local news report)<\/a><\/li>\n<li><a href=\"https:\/\/www.spacex.com\/launches\/\" target=\"_blank\" rel=\"noopener\">SpaceX (official launch information\/webcast)<\/a><\/li>\n<li><a href=\"https:\/\/www.viasat.com\/\" target=\"_blank\" rel=\"noopener\">Viasat (company overview\/press)<\/a><\/li>\n<li><a href=\"https:\/\/www.brevardfl.gov\/EmergencyManagement\" target=\"_blank\" rel=\"noopener\">Brevard County Emergency Management (local government advisory)<\/a><\/li>\n<li><a href=\"https:\/\/www.patrick.spaceforce.mil\/Units\/45th-Weather-Squadron\/\" target=\"_blank\" rel=\"noopener\">45th Weather Squadron (US Space Force forecast\/official)<\/a><\/li>\n<\/ul>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Wednesday, April 28, 2026 \u2014 SpaceX is scheduled to launch a Falcon Heavy from Kennedy Space Center at 10:13 a.m. ET carrying the ViaSat\u20113 F3 communications satellite into geostationary transfer orbit.
