CAPE CANAVERAL, Fla. — The world’s strongest rocket at present in operation took flight this morning (Nov. 1) for the primary time in additional than three years.
SpaceX’s Falcon Heavy rocket, which consists of three of the corporate’s modified Falcon 9 first-stage boosters strapped collectively, lifted off right this moment from Pad 39A right here at NASA’s Kennedy House Middle (KSC) at 9:41 a.m. EDT (1341 GMT) amid thick fog on the launch pad. The Heavy carried a handful of labeled payloads towards geostationary orbit for the U.S. Space Force on a mission referred to as USSF-44.
USSF-44 is the fourth launch for the Falcon Heavy general and its first since June 2019. That low flight price stands in stark distinction to SpaceX’s Falcon 9 workhorse, which has flown greater than as soon as per week this yr on common. And whereas the overwhelming majority of these Falcon 9 launches have used pre-flown boosters, right this moment’s Falcon Heavy launched on three brand-new first phases.

When this morning’s countdown clock hit zero, all 27 of the Falcon Heavy’s first-stage Merlin engines ignited with 64 metric tons of thrust to raise the massive rocket off the pad. About 2.5 minutes after liftoff, the launch automobile’s two facet boosters separated to carry out synchronized boost-back burns and start their return flight to Cape Canaveral.
Previous Falcon Heavy missions have additionally tried landings of the central booster on one in every of SpaceX‘s automated drone ships within the Atlantic Ocean. Nonetheless, the mass and orbital necessities of USSF-44’s payloads mandated that the core booster for this mission forgo touchdown and future re-use to be able to dedicate most gasoline for a direct insertion into geostationary orbit, about 22,000 miles (35,400 kilometers) above Earth.
At roughly 4 minutes after launch, the Falcon Heavy’s central core booster separated from the higher stage that sat atop it and commenced its descent towards a watery grave within the Atlantic Ocean. The higher stage, in the meantime, ignited its single Merlin engine to hold the satellites greater into orbit. Shortly thereafter, the 2 fairing halves defending the U.S.-44 payloads separated and commenced their very own reentry to Earth’s environment; SpaceX aimed to recuperate each of them for future reuse.
Eight minutes after launch, the 2 Falcon Heavy facet boosters carried out simultaneous touchdown burns. The duo landed efficiently 10 seconds later, at SpaceX’s Touchdown Zones 1 and a pair of at Cape Canaveral House Pressure Station, which is subsequent door to KSC.
“And there you’ve gotten it! As indicated by the large cheers, we now have efficiently landed each Falcon Heavy facet boosters at Touchdown Zone 1 and touchdown zone 2. What an unbelievable sight. With these two facet boosters this marks the a hundred and fiftieth and 151st general profitable landings of an orbital-class rocket,” Kate Tice, SpaceX high quality methods engineering supervisor, introduced throughout the stay launch broadcast.
Due to the labeled nature of the U.S.-44 payloads, the precise quantity and length of second-stage engine burns required to get them to their orbital vacation spot is unknown. Nonetheless, SpaceX’s earlier Falcon Heavy missions shed some mild on what might have been required.
Falcon Heavy’s February 2018 debut famously launched SpaceX CEO Elon Musk‘s cherry-red Tesla Roadster into interplanetary space with a model named Starman strapped into the driving force seat, sporting the identical kind of SpaceX flight go well with worn by Crew Dragon astronauts. Falcon Heavy flew once more in April 2019, when it launched the massive Arabsat-6A satellite, after which once more in June 2019 for a mission referred to as STP-2.
STP-2 was a mission for the U.S. navy that certified Falcon Heavy to fly Air Pressure and House Pressure payloads, and required the automobile’s second stage to carry out a number of engine burns and restarts. The success of STP-2 paved the way in which for USSF-44 to raise off right this moment.
The principle payload that flew right this moment, a satellite often known as USSF-44, is classed; little or no is understood about it. There is a bit extra details about Tetra-1, a second, smaller spacecraft that additionally rode the Heavy to orbit. Tetra-1 was constructed by the Boeing subsidiary Millennium House Programs. Based on Millenium’s website (opens in new tab), “TETRA-1 is a microsatellite created for varied prototype missions in and round geosynchronous Earth orbit.”
A number of tiny cubesats additionally hitched a experience on USSF-44 as nicely, according to EverydayAstronaut.com (opens in new tab), however details about them is sparse.
