Image: SpaceX SpaceX is getting ready to launch its first Falcon Heavy rocket in additional than a yr and a half. The Monday morning flight of the triple booster rocket from NASA’s Kennedy Space Center will characteristic the touchdown of the 2 facet boosters at Cape Canaveral Space Force Station. The mission will ship the ViaSat-3 Flight 3 communications satellite tv for pc to a geosynchronous switch orbit. The six-metric-ton satellite tv for pc is about to deploy from the rocket’s higher stage practically 5 hours after leaving the pad. “It’s kind of the end of an era. We’ve been working this program for over 10 years now. So that’s a good chunk of life that’s gone by over the course of the program,” mentioned Dave Abrahamian, Viasat’s vice chairman of Satellite Systems. “It’s a different world now than when we started the program. Back then, we had a handful of satellites in orbit. Since then, we’ve launched the two ViaSat-3s, we merged with Inmarsat, we’ve got the third one (ViaSat-3) ready to go now. So totally different world, different feeling, and its pretty cool to have been part of it all.” Liftoff from Launch Complex 39A is scheduled for 10:21 a.m. EDT (1421 UTC), the opening of an 85-minute window. The Falcon Heavy rocket will fly on an easterly trajectory upon launch. Spaceflight Now may have stay protection starting about two hours previous to liftoff.

Meteorologists mentioned they’re waiting for violations of the cumulus cloud and the floor electrical fields guidelines. “A Carolina Low is expected to push a weak back door cold front through central Florida early Monday morning,” launch climate officers wrote of their forecast. “With the primary window opening around the time the sea breeze will develop, the position of that frontal boundary will determine if clouds are enhanced over the Spaceport.” The three boosters SpaceX will fly on the mission are a mixture of previous, new, and model new. The two facet boosters, tail numbers 1072 and 1075, might be flying for a second and twenty second time respectively. Those will separate from the middle core, tail quantity B1098, and goal landings at Landing Zone 2 (LZ-2) and Landing Zone 40 (LZ-40). The latter of the 2 is adjoining to Space Launch Complex 40 and is to the north of LZ-2. SpaceX won't try and get well B1098 and will probably be expended into the Atlantic Ocean, concluding its first and solely flight. SpaceX’s design for the ViaSat-3 F3 mission patch. Graphic: SpaceX Flying Falcon Heavy The launch of the ViaSat-3 F3 mission marks the twelfth flight of a Falcon Heavy rocket, which made its debut in 2018. Two of these missions carried ViaSat-3 satellites onboard. Abrahamian famous that the time for on-orbit commissioning might be shorter than that of the Viasat-3 F2 satellite tv for pc which flew on a United Launch Alliance Atlas 5 rocket. He mentioned orbit elevating to the working place on the 158.55 levels East place alongside the equator will take about two months.

So, it’s a very [electric propulsion]-friendly orbit.” He mentioned it's going to take at the least a few months after that to undergo the varied deployment phases on the satellite tv for pc and conduct checkouts earlier than the satellite tv for pc producer, Boeing, fingers the car over to Viasat for operational use. ViaSat-3 F2, which flew on Atlas 5 in November 2025, remains to be finishing its on orbit checkout and is slated to start operational service within the close to future. We requested Abrahamian if he noticed any challenges or key variations between the work to vertically combine Viasat’s payload versus horizontal integration, since his firm has achieved each. “If you had asked me that before F2 happened and before all the weather challenges with stacking F2 I would have said no. But now, having been through that and doing this, there’s certainly much more flexibility in not having as many constraints on you when you’re doing horizontal integration,” Abrahamian mentioned. “It presents its own set of challenges when you have to roll out to the pad, align very carefully, to pad infrastructure and then go vertical. So that’s a challenge that Atlas doesn’t have. Each system seems to work for each provider.” The SpaceX Falcon Heavy rocket supporting the ViaSat-3 F3 mission lies within the horizontal place at Launch Complex 39A at NASA’s Kennedy Space Center.

We can put multiple beams in an area as needed. So we really don’t have the issue of trapped capacity here. So it’s a matter of following the demand wherever it is, within that spacecraft’s field of view.” The ViaSat-3 Flight 3 satellite tv for pc is seen inside Boeing’s check amenities in El Segundo, CA.
