SpaceX seeks second attempt at Falcon Heavy launch following weather scrub on Monday – Spaceflight Now

SpaceX will strive once more Wednesday to launch its Falcon Heavy rocket from NASA’s Kennedy Space Center, following a last-minute scrub Monday on account of poor weather.

The heavy carry rocket will use about 5.1 million kilos of thrust to propel ViaSat-3 F3 to a geosynchronous switch orbit, the third and last satellite tv for pc within the ViaSat-3 sequence.

Liftoff from Launch Complex 39A is scheduled for 10:13 am EDT (1413 UTC), at the opening of an 85-minute window. Deployment of the six metric ton spacecraft is anticipated practically 5 hours after taking off from Florida’s Space Coast.

“As the spacecraft enters service, I think what you’re going to see is more and more of our airline customers providing free use of airborne WiFi. And with recent updates to the networks and everything, a number of those have enabled free streaming,” stated Dave Abrahamian, Viasat’s vp of Satellite Systems.

“You can stream Netflix at 4K within the sky. When we began many, a few years in the past with ViaSat-1, you could not do this. Just with the ability to get fundamental SMS or e-mail service within the air was an enormous deal, however now we’re as much as streaming in 4K. So I believe [the public will] respect the outcomes of this system with out essentially understanding how we received there, what permits it.”

Spaceflight Now may have dwell protection of the mission starting about two hours previous to liftoff.



The forty fifth Weather Squadron forecast a 90 p.c likelihood for favorable weather in the course of the window, a marked enchancment from the 55 p.c forecast Monday. The main concern for meteorologists this time round is the prospect of thick clouds.

The three SpaceX boosters will fly on the mission are a mixture of outdated, new, and model new. The two aspect boosters, tail numbers 1072 and 1075, will probably be flying for a second and twenty second time respectively.

Since SpaceX has retired certainly one of its unique touchdown zones at Cape Canaveral, the dual aspect boosters will return to websites about ten miles aside. On touchdown at Landing Zone 2 (LZ-2) and the opposite at Landing Zone 40 (LZ-40), adjoining to Space Launch Complex 40.

SpaceX is not going to attempt to get better the core stage, model new booster B1098, and will probably be discarded within the Atlantic Ocean.

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 will probably be shorter than that of the Viasat-3 F2 satellite tv for pc which flew on a United Launch Alliance Atlas 5 rocket. He stated orbit elevating to the working place at the 158.55 levels East place alongside the equator will take about two months.

“Falcon Heavy is a more powerful vehicle than Atlas 5 was, so they can put us in a more favorable transfer orbit for the electric propulsion,” Abrahamian stated. “So they’re going to drop us off in an orbit, hopefully, that is just below [geostationary Earth orbit] apogee-wise, about 23,000 kilometers perigee-wise, and only about three degrees of inclination. So, it’s a very [electric propulsion]-friendly orbit.”

He stated it should take at least a few months after that to undergo the assorted deployment phases on the satellite tv for pc and conduct checkouts earlier than the satellite tv for pc producer, Boeing, palms the car over to Viasat for operational use.

ViaSat-3 F2, which flew on Atlas 5 in November 2025, continues 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 carried out 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 stated. “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.”



Adding capability

This third and last satellite tv for pc within the ViaSat-3 constellation will goal its space of ​​protection over the Asia-Pacific area and is meant so as to add greater than 1 Terabit per second (Tbps) of capability to the general Viasat community.

“We have a number of airline customers in the APAC region that are really anxious to get this capacity online so they can start serving their customers better,” Abrahamian stated. “Two of the hallmarks of the ViaSat-3 constellation are an enormous quantity of simply absolute capability, but in addition the flexibleness to place it wherever you want it, everytime you want it.

“So it’s not like a traditional satellite, like a ViaSat-1, or Ka sat, or most of the Inmarsat fleet, where you’ve got a single feed per beam, beam locations are fixed, spectrum allocations are fixed and you might overload one beam over here and another beam doesn’t have anybody in it and you can’t move that capacity.”

Abrahamian stated the benefit of those newer satellites is their general flexibility.

“ViaSat-3 because we’re using a phased array technology and our antennas onboard, we can form a beam wherever we need it,” he stated. “We can allocate spectrum to it as we need it. We can put multiple beams in an area as needed. 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.”
