Konstelacja ViaSat-3 składa się z trzech satelitów, z których każdy ma zapewniać zasięg w określonym regionie świata: ViaSat-3 F1 obejmie Amerykę;
ViaSat-3 F2 obejmie Europę, Bliski Wschód i Afrykę (EMEA);
ViaSat-3 F3 obejmie regiony Azji i Pacyfiku (APAC).
Ze względu na trudności techniczne związane z F1, które znacznie obniżyły jego przepustowość, po wystrzeleniu F2 obejmie on Amerykę, a F1 zostanie przeniesiony do regionu EMEA.

Boeing Delivers ViaSat-3 Flight 3 Spacecraft to Viasat
- Third satellite built on Boeing’s 702MP+ platform will provide connectivity across the Asia-Pacific region
- The satellite arrived in Cape Canaveral Space Force Station, Florida today, where Boeing and Viasat teams are preparing it for an upcoming SpaceX Falcon Heavy launch
CAPE CANAVERAL SPACE FORCE STATION, Fla. Apr. 7, 2026 — Boeing [NYSE: BA] announced today, delivery of the ViaSat-3 Flight 3 (VS-3 F3) spacecraft to Viasat. Built on Boeing’s high-power 702MP+ platform and integrated at Boeing’s El Segundo facility in California, VS-3 F3 will provide the Asia-Pacific region with state-of-the-art technology to maximize efficient, flexible bandwidth deployment and enhanced performance for commercial mobility and defense customers, among others, in high-density markets across the region.
“ViaSat-3 F3 reflects the strength of Boeing’s 702 family and our long-standing partnership with Viasat,” said Ryan Reid, president of Boeing Satellite Systems International. “With this delivery, we’re providing a high-power, flexible platform designed to support Viasat’s next-generation connectivity mission which is proving more valuable every single day. We are thankful for their partnership and trust.”
Following final spacecraft integration, testing and verification at Boeing’s El Segundo, California factory, Boeing officially delivered the satellite to Cape Canaveral Space Force Station, Florida where Boeing and Viasat teams will support pre-launch processing and mission preparations ahead of a SpaceX Falcon Heavy launch. The delivery marks Boeing’s latest major milestone on the ViaSat-3 program and the completion of Boeing’s spacecraft production and integration work for VS‑3 F3.
“The delivery of ViaSat-3 F3 marks an important milestone for the program and for the customers who will rely on it for resilient, secure, flexible and high-performance connectivity across the APAC region,” said Dave Abrahamian, vice president of Space Systems, Viasat. “Throughout the ViaSat-3 program, Boeing’s platform performance and mission operations have been essential to achieving these goals for our business and our customers.”
Built on Boeing’s flight-proven 702 family, the 702MP+ platform was developed to support larger, more power-intensive payloads while preserving the reliability and flexibility customers expect from Boeing spacecraft. For ViaSat-3, Boeing scaled the platform to accommodate larger solar arrays, higher-capacity batteries, upgraded supporting electronics and large deployable radiators to manage the thermal demands of a high-power mission.
The platform also incorporates all-electric propulsion, building on Boeing’s earlier 702SP heritage while extending that efficiency into the larger 702MP class. To support ViaSat-3’s payload and reflector configuration, Boeing enhanced structural elements and attitude-control performance so the spacecraft can maintain precise pointing despite the size and flexibility of the system.
With VS-3 F1 already providing commercial airline connectivity and VS-3 F2 currently advancing towards entering service over the Americas, VS-3 F3 will extend the constellation’s coverage to the AsiaPacific, enabling expanded connectivity options for customers across the region.
Boeing and Viasat will jointly support launch operations in Florida, continuing the collaboration that brought this satellite from design and integration to delivery.

Over at LC-39A, the strongback has picked up the reaction frame, which is a good sign SpaceX is preparing to move the Transporter-Erector to the hangar for integration with Falcon Heavy! Launch continues to be targeted for April 27th at 14:21 UTC.
📸 https://youtube.com/watch?v=thfYPsRqxmw
The reaction frame is the lower part of the T-E, and most notable contains the holddown clamps. During a launch, it gets disconnected from the strongback to allow it to throw back at T-0. In order to reconnect these parts, the strongback needs to raise and lower.

SpaceX launches 6-ton ViaSat-3 F3 satellite on Falcon Heavy rocket
April 29, 2026 Will Robinson-Smith
(...) Less than 2.5 minutes after liftoff, the side boosters, tail numbers B1072 and B1075, throttled down on their engines and separated from the center core, tail number B1098. Both side boosters performed a boost back burn lasting more than a minute to put them on track towards two landing pads at Cape Canaveral Space Force Station. The center core, B1098, continued on for another 90 seconds before the second stage separated and began the first of three burns over five hours to deliver the ViaSat-3 F3 satellite to a geosynchronous transfer orbit.
Less than eight minutes after the flight began, B1072 and B1075 reignited their center engines and touched down at Landing Zone 2 and Landing Zone 40. This was the first Falcon Heavy rocket launch to use SpaceX’s newest landing pad at Space Launch Complex 40. As with most Falcon Heavy missions, SpaceX did not recover the center core. (...)
After the satellite is released, there will be a roughly two-month period of orbit raising for the spacecraft before it reaches its operating position at 155.58 degrees East along the equator. (...)

Niezły kontrast w stosunku do ostatniej porażki lotu New Glenna. Można narzekać na Starshipa i słusznie, ale Falcony to prawdziwa gwiazda w stajni SpaceX. Statki Dragon czy satelity Starlinka też robią prawidłowo swoją robotę. Czekamy z niecierpliwością na sukces Starshipa ! Mniejmy nadzieje że problemy już są za nami!

Jaki kontrast? Jaki sens ma porównanie rakiety New Glenn, która po raz pierwszy wystartowała w zeszłym roku i wykonała dopiero 3 misje do Falcona Heavy? No i przypomnę, że początki Falcona 9/Dragon było trudne. 28 czerwca 2015r Falcon 9 z Dragonem eksplodował po 139 sekundach lotu, a rok później 1 września 2016r Falcon 9 eksplodował na platformie startowej z satelitą wartym kilkaset milionów dolarów. W 2019r Dragon eksplodował podczas naziemnego testu silników.
Fanatycy Muska przy awarii 2 stopnia New Glenn - BO za ma mało doświadczenia, firma nie ogarnia prawidłowego wysyłania satelitów.
Fanatycy Muska, kiedy to Falcon 9 w 19 locie eksploduje i przed 29 lotem eksploduje przed testem SF i rozwala platformę startową - ...
A co do Falcona Heavy to jest to słaba rakieta. 18 miesięcy przerwy po poprzednim locie, satelita, która waży tylko 6400kg. New Glenn za kilka lat będzie lepszą alternatywą dla FH jak już dostanie od wojska certyfikację.

🛰️ 32,788 km up. That crescent in the background is Earth.
Viasat 3 F3 is now the third of three satellites forming a global broadband constellation. Combined capacity: over 1 terabit per second across the entire planet.
The first Viasat 3 satellite failed on deployment in 2023. The antenna never fully deployed. A $700 million loss.
This one just confirmed deployment at T+4:58. The crescent Earth behind it is not a dramatic backdrop. It's the finish line.

Rakieta SpaceX Falcon Heavy wyniosła misję ViaSat-3 F3 (satelitę ViaSat-3 Azji i Pacyfiku) na orbitę geostacjonarną z kompleksu startowego 39A (LC-39A) w Centrum Kosmicznym im. Kennedy'ego NASA na Florydzie, 29 kwietnia 2026 roku o godzinie 14:13 UTC (10:13 EDT). Jeden z bocznych boosterów (B1075) wcześniej wspierał 21 misji: SDA Tranche 0 (SDA-0A), SARah-2/3, Transporter-11 i 18 misji Starlink. Drugi boczny booster (B1072) wcześniej wspierał start misji GOES-U. Po oddzieleniu się stopni, dwa boczne boostery Falcon Heavy wylądowały na strefach lądowania SpaceX Landing Zones 2 and 40 (LZ-2 and LZ-40) w Stacji Sił Kosmicznych Cape Canaveral na Florydzie. Ze względu na wymagania misji nie planowano odzyskania centralnego stopnia rakiety (B1098).

Czy w tym starcie doszło do awarii jednego lub dwóch silników członów pobocznych FH?
Nie. Ładunek jest bardzo lekki, więc przed separacją bocznych boosterów wyłączają jeden silnik lub w niektórych misjach nawet dwa silniki, aby nadmiernie nie obciążać rakiety. Boczne booster po separacji mają nawet po 2-3t więcej paliwa w porównaniu do zwykłej misji na Falconie 9.
