KENNEDY SPACE CENTER, FL – Minutes after going vertical at pad 39A at lunchtime Saturday, Jan. 14, SpaceX suddenly delayed the weekend liftoff of their triple stick Falcon Heavy rocket by 24 hours from Saturday evening to Sunday evening Jan. 15, from Florida’s Space Coast, the company announced in a cryptic tweet Saturday afternoon for the mission involving launch of several national security payloads for the United States Space Force.
No explanation was publicly given for the launch delay.
The mission entails the first launch of the mammoth Falcon Heavy vehicle in 2023 from the Kennedy Space Center in Florida that generates 5.1 million pounds of liftoff thrust – that could be followed by as many as four additional Falcon Heavy launch throughout the calendar year.
Very exciting also is that both side boosters will return to the Cape for near simultaneous land landing sending multiple sonic booms screaming out across the Space Coast region.
We heard from sources that the delay is related to the insufficient supply of liquid Nitrogen trucked into the Cape thats required to support launch of the very powerful 23 story tall triple core rocket.
The semi-classified mission designated USSF-67 for the United States Space Force is retargeted for a dinnertime weekend liftoff Sun. Jan. 15, carrying a pair of critical military satellites in a stacked configuration encapsulated in the nose cone to geosynchronous orbit (GEO).
SpaceX announced they are rescheduling liftoff to Sunday, Jan. 15 for liftoff of the USSF-67 national security mission at 5:56 p.m. EDT (2256 GMT) from Launch Complex 39A on NASA’s Kennedy Space Center.

The weather outlook for Sunday is excellent.
Space Force meteorologists forecast over 90% GO favorable launch weather outlook
The launch window runs just over a half hour until 6:34 p.m. ET (2334 GMT) on Jan. 15.
USSF-67 is comprised of two co-manifested military satellites stacked on top of one another inside the nose cone used to transmit military communications data between top military and government leaders and to transport experimental research and technology development payloads to space, per the Space Force.
Overall the 2 satellites aboard comprise 5 satellites that will be delivered to geosynchronous orbit and some 22,000 miles (36,000 km) above the equator.
This USSF-67 mission counts as only the 5th launch of the still sparsely used Falcon Heavy rocket since its first launch in 2018.
The rocket had just rolled out horizontally to the pad early Saturday morning about a quarter mile from its processing hanger just outside the pad perimeter fence during a several hour period.

After a lengthy multi hour pause the rocket was final raised vertical around the 1 p.m. hour
Shortly after going vertical, the launch delay was announced by SpaceX and the Space Force just before 2 p.m. ET.
Following stage separation, Falcon Heavy’s two first stage side boosters will return to Earth and land on LZ-1 and LZ-2 back at Cape Canaveral and the Space Coast – for near simultaneous and very exciting touchdowns at LZ-1 & LZ-2 some eight minutes after liftoff – sending screaming sonic booms across the region.
The Falcon Heavy is currently the second most powerful operational rocket in the world – having been recently eclipsed by NASA’s Artemis Moon rocket
It was launched only 4 times previously since its debut test flight mission in 2018 with a Tesla Roadster car from SpaceX CEO Elon Musk.
The USSF-67 mission for the United States Space Force counts as the fifth Falcon Heavy mission.
The prior mission was launched on 1 Nov. 2022 – also a classified mission for the U.S. Space Force on USSF-44
Up to 5 Falcon Heavy missions will be launched in 2023
Multiple satellites will be carried to orbit by the Falcon Heavy featuring 1 new booster cores and two recycled side cores from the prior launch on Nov. 1
The center core will be expended since the Space Force needs to use all the thrust available from the rocket.
The Falcon Heavy is comprised of three Falcon 9 boosters lashed together.
The side cores are recycled from the USSF-44 mission when they also landed back at the Cape LZ-1 and LZ-2 and will save significantly on launch costs.
“The efficiencies garnered from reusability benefit all customers, adding flexibility to a dynamic launch queue and cost savings,” said the Space Force.
Payload details from the Space Force:
The forward spacecraft, SSC’s Continuous Broadcast Augmenting SATCOM (CBAS)-2, is a satellite destined for geosynchronous orbit to provide communications relay capabilities in support of our senior leaders and combatant commanders. The mission of CBAS-2 is to augment existing military satellite communication capabilities and continuously broadcast military data through space-based satellite relay links.
The second spacecraft, the Long Duration Propulsive ESPA (LDPE)-3A, is used to rapidly place multiple, diverse payloads into orbit and provide critical data to inform and influence future U.S. Space Force programs. This LDPE-3A mission includes two SSC payloads: catcher and WASSAT, and three payloads developed by the Space Rapid Capabilities Office (SRCO). The SRCO payloads include two operational prototypes for enhanced situational awareness, and an operational prototype crypto/interface encryption payload providing secure space-to-ground communications capability. The LDPE spacecraft will continue to provide access to space for multiple DoD space Science & Technology (S&T) demonstration experiments.
“This is a complex mission and truly represents what Assured Access to Space is about and is why we’re so enthusiastic about this upcoming launch…our second Falcon Heavy in just months,” said Maj. Gen. Stephen Purdy, program executive officer for Assured Access to Space, in a statement.
“The teamwork I’ve seen preparing for this launch has just been exceptional. We’ve worked side-by-side with SpaceX to ensure all boxes are checked…that all systems are GO. And our processes for getting to that ‘go’ decision at LRR are thorough and constantly evolve, so they’re also more efficient than ever.”
The path to launch was paved after SpaceX conducted a full duration static fire test of the first stage engines on Tuesday, Jan. 10.
The Falcon Heavy was tested in the ‘headless’ configuration of the first and second stages – meaning there was no nose cone or payload on top to keep the multi-billion dollar collection of U.S. Space Force satellites codenamed USSF-67 safe in case something went awry during the engine firing.
After SpaceX engineers fueled the Falcon Heavy with RP-1 and liquid oxygen propellants they ignited all 27 first stage Merlin 1D engines on all three Falcon 9 cores at 12:45 PM EDT Tuesday (1745 GMT) – thereby generating 5.1 million pounds of thrust while hold down clamps kept the triple core rocket firmly on top of the pad at Launch Complex 39A on NASA’s Kennedy Space Center.
The brief but full duration test fire lasted several seconds and sent a massive exhaust vapor cloud spewing from the base of the rocket and out through the flame trench and upwards swirling and whipping in the winds.
