The most powerful rocket in operation took flight for the first time in three years.

The Falcon Heavy rocket lifted off at 9:41 a.m. from Pad 39A at the Kennedy Space Center. Thick fog at the launch pad. The Heavy was used on a mission for the U.S. space force.

It is the first launch for the Falcon Heavy in over a year. The company's workhorse, the Falcon 9, has flown more than once per week on average this year. The majority of the Falcon 9 launches have used pre-flown boosters.

Since the beginning of the year, there has been no flights of the Falcon Heavy rocket.

When the clock hit zero this morning, all 27 engines of the first stage of the Falcon Heavy lifted off. After 2.5 minutes after liftoff, the launch vehicle's two side boosters separated and began their return flight.

There have been attempts to land the central booster on one of the automated drones. In order to dedicate maximum fuel for a direct entry into the atmosphere, the core booster for this mission had to forgo landing and future re- use.

Four minutes after launch, the central core booster separated from the upper stage and began its descent into the Atlantic. The upper stage's single engine was used to propel the satellites higher into the sky. The two halves of the USSF-44 payloads separated and were to be recovered for reuse.

Two side boosters performed simultaneous landing burns after launch. The duo landed at Cape Canaveral Space Force Station, which is next to the Kennedy Space Center.

You have it!" The Falcon Heavy side boosters were successfully landed at landing zones 1 and 2. An amazing sight. Kate Tice, the quality systems engineering manager, announced during the live launch broadcast that this marks the 150th and 151st successful landings of an Orbital class rocket.

The number and duration of second-stage engine burns required to get the USSF 44 payloads to their destination is unknown because of the classified nature of the mission. TheFalcon Heavy missions shed some light on what may have been required.

The same type of flight suit worn by Crew Dragon astronauts was used to launch a mannequin named Starman into space. The big Arabsat 6A satellite was launched by Falcon Heavy in April and again in June.

The mission required the vehicle's second stage to perform several engine burns and restarts in order to qualify Falcon Heavy to fly Air Force and Space Force missions. The success of STP-2 paved the way for the lift off of USSF 44.

Very little is known about the satellite known as USSF 44 that flew today. There is more information about the smaller craft that went to the Heavy. Millennium Space Systems is a division of the Boeing company. Millenium's website states thatTETRA-1 is a microsatellite created for various prototype missions.

There are a few cubesats that hitched a ride on USSF 44, but there is no information about them.
