SpaceX’s Falcon Heavy Returns: ViaSat-3 F3 Mission Marks First Launch in 18 Months
SpaceX is set to reignite its most powerful operational rocket, the Falcon Heavy, today in a mission that underscores the company’s dominance in heavy-lift launches. The ViaSat-3 F3 satellite, the final piece of Viasat’s next-generation broadband constellation, will ride atop the triple-core rocket from Kennedy Space Center’s Launch Complex 39A (LC-39A) in Florida. Liftoff is scheduled for 10:21 a.m. ET (14:21 UTC), with an 85-minute launch window available. A backup opportunity is slated for Tuesday, April 28, at 10:17 a.m. ET.
Why This Launch Matters
The Falcon Heavy hasn’t flown since October 2024, when it launched NASA’s Europa Clipper mission to Jupiter’s icy moon. Today’s mission marks its 12th flight overall and the first in 18 months—a hiatus that reflects both the rocket’s specialized role and SpaceX’s shift towardStarship development. With 5.1 million pounds of thrust at liftoff, Falcon Heavy remains the second-most powerful operational rocket in the world, surpassed only by NASA’s Space Launch System (SLS).
The Payload: Completing Viasat’s Global Broadband Network
The ViaSat-3 F3 satellite is the third and final installment in Viasat’s Ka-band broadband constellation, designed to deliver high-speed internet across the globe. Here’s how the trio breaks down:
- ViaSat-3 F1 (Americas): Launched in May 2023 aboard a Falcon Heavy, this satellite covers North and South America. However, Viasat reported a reflector deployment anomaly post-launch, which significantly reduced its capacity. The company has since adjusted its coverage plans to mitigate the issue.
- ViaSat-3 F2 (EMEA): Launched in November 2025 on a United Launch Alliance Atlas V 551, this satellite serves Europe, the Middle East, and Africa. It is expected to reach full operational status later this year.
- ViaSat-3 F3 (Asia-Pacific): Today’s launch will deliver this satellite to geostationary orbit, where it will cover the Asia-Pacific region. Originally slated for an Ariane 6 rocket, Viasat switched to Falcon Heavy due to delays in the European launcher’s development.
Once all three satellites are operational, Viasat aims to provide global Ka-band coverage, offering high-speed internet to underserved regions, including remote areas and maritime routes. The constellation is expected to compete with other satellite broadband providers like Starlink and OneWeb, though Viasat’s geostationary approach differs from the low-Earth orbit (LEO) networks of its rivals.
A First for SpaceX: Dual Landing Zones
Today’s mission will feature a historic first for SpaceX: the simultaneous use of two landing zones for the Falcon Heavy’s side boosters. The two side cores will execute a return-to-launch-site (RTLS) maneuver, touching down at:
- Landing Zone 2 (LZ-2): Located at Cape Canaveral Space Force Station.
- Landing Zone 40 (LZ-40): Also at Cape Canaveral, this pad is typically used for Falcon 9 landings.
The center core, however, will be expended—a common practice for Falcon Heavy missions with high-energy payloads like ViaSat-3 F3, which is bound for geostationary transfer orbit (GTO). This expendable approach allows SpaceX to maximize the rocket’s performance for heavy payloads.
How to Watch the Launch Live
SpaceX will provide a live webcast of the launch, beginning approximately 15 minutes before liftoff. You can watch the stream on:
Weather conditions for Monday’s launch window are currently 60% favorable, according to the 45th Weather Squadron. If the launch is scrubbed, the backup window on Tuesday offers 70% favorable conditions.
What’s Next for Falcon Heavy?
While Falcon Heavy has flown only 11 times since its debut in 2018, its manifest remains robust. Upcoming missions include:
- NASA’s Psyche mission (2026): A delayed but highly anticipated mission to explore the metal-rich asteroid 16 Psyche.
- U.S. Space Force missions: Falcon Heavy is slated to launch several classified payloads for the Space Force in the coming years, including the USSF-52 and USSF-67 missions.
- Commercial launches: Companies like Astranis and Inmarsat have booked Falcon Heavy for future satellite deployments.
Despite the rise of Starship, SpaceX’s fully reusable super-heavy lift rocket, Falcon Heavy remains a critical asset for payloads that require its unique combination of power and precision. Starship’s development, however, could eventually relegate Falcon Heavy to niche roles—though for now, it remains the king of heavy-lift launches.

FAQ
Why is Falcon Heavy launching after 18 months?
Falcon Heavy is a specialized rocket designed for heavy payloads bound for high-energy orbits, like geostationary transfer orbit (GTO). Most of SpaceX’s launches use the smaller Falcon 9, which is more cost-effective for lighter payloads. The 18-month gap reflects the limited demand for Falcon Heavy’s capabilities, as well as SpaceX’s focus on developing Starship.
What makes Falcon Heavy different from Falcon 9?
Falcon Heavy consists of three Falcon 9 first-stage boosters strapped together, with a modified center core and an upper stage. This configuration allows it to generate 5.1 million pounds of thrust—more than twice that of a single Falcon 9. While Falcon 9 is optimized for low-Earth orbit (LEO) missions, Falcon Heavy can deliver heavier payloads to higher orbits, including GTO and beyond.
Why is the center core expended during this mission?
For high-energy missions like ViaSat-3 F3, which require the payload to reach geostationary transfer orbit (GTO), the Falcon Heavy’s center core is often expended to maximize performance. This means the core is not recovered, allowing it to use all its fuel to propel the payload rather than reserving some for landing. The side boosters, however, are recovered via RTLS landings.
How does ViaSat-3 compare to Starlink?
ViaSat-3 and Starlink represent two different approaches to satellite broadband:
| Feature | ViaSat-3 | Starlink |
|---|---|---|
| Orbit | Geostationary (35,786 km) | Low-Earth Orbit (550 km) |
| Latency | Higher (~600 ms) | Lower (~20-40 ms) |
| Coverage | Regional (one satellite per region) | Global (thousands of satellites) |
| Speed | Up to 100+ Mbps | Up to 150+ Mbps (with premium plans) |
| Target Market | Underserved regions, maritime, aviation | Consumers, businesses, rural areas |
ViaSat-3’s geostationary orbit allows it to cover large regions with a single satellite, while Starlink’s LEO constellation provides lower latency and global coverage with thousands of satellites.
What happens if the launch is delayed?
If weather or technical issues prevent Monday’s launch, SpaceX has a backup window on Tuesday, April 28, at 10:17 a.m. ET. If further delays occur, SpaceX will announce a new target date. The 45th Weather Squadron monitors conditions, with factors like lightning, wind, and cloud cover playing critical roles in the travel/no-go decision.
The Bigger Picture: Satellite Broadband’s Role in Global Connectivity
The ViaSat-3 constellation is part of a broader trend of satellite broadband providers aiming to bridge the digital divide. With 2.6 billion people still offline as of 2026, according to the International Telecommunication Union (ITU), satellite internet offers a promising solution for remote and underserved communities. However, challenges remain:
- Cost: Satellite broadband can be expensive to deploy and maintain, often resulting in higher prices for consumers.
- Latency: Geostationary satellites like ViaSat-3 suffer from higher latency due to their distance from Earth, making them less ideal for real-time applications like gaming or video calls.
- Regulatory Hurdles: Spectrum allocation and licensing can delay deployments, as seen with SpaceX’s recent FCC denial for direct-to-device Starlink services.
- Space Debris: The proliferation of satellites raises concerns about orbital congestion and the risk of collisions.
Despite these challenges, the satellite broadband market is poised for growth. Companies like Viasat, SpaceX, and AST SpaceMobile are investing billions to expand their constellations, with the goal of providing ubiquitous connectivity. Today’s launch is a step toward that future—one where geography no longer dictates access to the internet.
As Falcon Heavy roars back to life, it serves as a reminder of the rapid evolution of space technology. From launching sports cars to deploying global broadband networks, SpaceX continues to push the boundaries of what’s possible. For now, all eyes are on LC-39A, where history is set to be made—again.
