SpaceX is gearing up for its busiest Falcon Heavy megarocket launch but and now, because of the U.S. Air Drive, we all know what the epic rideshare appears like.
When the subsequent SpaceX Falcon Heavy launches on Monday (June 24) from NASA’s historic Pad 39B on the Kennedy Area Middle in Florida, the heavy-lift rocket can be carrying 24 completely different satellites for the Air Drive’s Area Check Program-2 mission. In case you’re questioning what two dozen satellites seem like inside a Falcon Heavy nostril cone, surprise no extra.
In a Twitter put up Tuesday (June 18), the Air Drive Area & Missile Techniques Middle in control of the STP-2 mission confirmed simply how the 24 satellites are stacked contained in the payload fairing.
“The three,700 kg [8,157 pounds] Built-in payload Stack (IPS) for STP2 has been accomplished!” Air Drive officers wrote within the put up. “Take a look earlier than it blasts off on the primary DoD Falcon Heavy launch!”

The STP-2 mission is scheduled to launch someday throughout a four-hour window that opens Monday night time at 11:30 p.m. EDT (0330 June 25 GMT). Will probably be the third Falcon Heavy launch for SpaceX , however the first to hold a couple of satellite tv for pc at time.
The primary Falcon Heavy mission, a take a look at flight in February 2018, carried a Tesla roadster owned by SpaceX CEO Elon Musk and Starman, a model wearing an official SpaceX spacesuit. (The Roadster and Starman are nonetheless on the market in deep house.)
A single huge satellite tv for pc, the 14,241-pound (6,460 kilograms) Arabsat 6A launched atop SpaceX’s second Falcon Heavy on April 11 of this 12 months. The 2 first-stage facet boosters used to launch Arabsat 6A can be reused on the STP-2 mission, SpaceX has mentioned.

The 24 satellites of the STP-2 mission comprise a various group of spacecraft constructed by NASA, the U.S. navy, Nationwide Oceanic and Atmospheric Administration, pupil groups from universities. They embrace a NASA atomic clock, a satellite tv for pc to check “inexperienced” spacecraft propellant and the LightSail 2 photo voltaic sail for the Planetary Society, amongst others.
“The STP-2 mission can be among the many most difficult launches in SpaceX historical past with 4 separate upper-stage engine burns, three separate deployment orbits, a remaining propulsive passivation maneuver and a complete mission length of over six hours,” SpaceX wrote in a mission description.
SpaceX added that the flexibility to hold many satellites without delay, in addition to launch with used boosters, are key milestones for the mission.
“The STP-2 multi-manifest (rideshare) launch will exhibit the capabilities of the SpaceX Falcon Heavy launch automobile and supply essential knowledge supporting certification for future Nationwide Safety Area Launch (NSSL) missions,” SpaceX officers mentioned. “As well as, SMC will use this mission as a pathfinder for the event of mission assurance insurance policies and procedures associated to the reuse of launch automobile boosters.”
SpaceX frequently reuses the primary stage boosters of its smaller Falcon 9 rockets, in addition to its uncrewed Dragon cargo ships that ship NASA cargo to the Worldwide Area Station. SpaceX has been steadily creating reusable rocket know-how to decrease the price of spaceflight.
Lastly, whereas 24 satellites could look like rather a lot, SpaceX has truly launched extra on the similar time on its Falcon 9 rockets. Final 12 months, the corporate launched 64 tiny satellites similtaneously a part of a rideshare mission brokered by the corporate Spaceflight.
Simply final month, SpaceX launched the primary 60 of its Starlink web satellites to put the inspiration of a constellation aimed to quantity within the 1000’s of satellites.
