This Is What 2 Dozen Satellites Look Like Packed for Launch on a SpaceX Falcon Heavy


SpaceX is gearing up for its busiest Falcon Heavy megarocket launch but and now, because of the U.S. Air Pressure, we all know what the epic rideshare seems like. 

When the next SpaceX Falcon Heavy launches on Monday (June 24) from NASA’s historic Pad 39B on the Kennedy House Heart in Florida, the heavy-lift rocket will probably be carrying 24 completely different satellites for the Air Pressure’s House Check Program-2 mission. When you’re questioning what two dozen satellites appear like inside a Falcon Heavy nostril cone, surprise no extra. 

In a Twitter post Tuesday (June 18), the Air Pressure House & Missile Methods Heart in command of the STP-2 mission confirmed simply how the 24 satellites are stacked contained in the payload fairing. 

“The 3,700 kg [8,157 pounds] Integrated payload Stack (IPS) for STP2 has been completed!” Air Pressure officers wrote within the put up. “Have a look before it blasts off on the first DoD Falcon Heavy launch!”

The STP-2 mission is scheduled to launch someday throughout a four-hour window that opens Monday evening at 11:30 p.m. EDT (0330 June 25 GMT). It will likely be the third Falcon Heavy launch for SpaceX , however the first to hold multiple 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 still out there in deep house.) 

A single large 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 yr. The 2 first-stage aspect boosters used to launch Arabsat 6A will probably be reused on the STP-2 mission, SpaceX has stated. 

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, scholar groups from universities. They embody a NASA atomic clock, a satellite tv for pc to test “green” spacecraft propellant and the LightSail 2 solar sail for the Planetary Society, amongst others.

“The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration 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 demonstrate the capabilities of the SpaceX Falcon Heavy launch vehicle and provide critical data supporting certification for future National Security Space Launch (NSSL) missions,” SpaceX officers stated. “In addition, SMC will use this mission as a pathfinder for the development of mission assurance policies and procedures related to the reuse of launch vehicle boosters.”

SpaceX repeatedly 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 House Station. SpaceX has been steadily growing reusable rocket expertise to decrease the price of spaceflight. 

Lastly, whereas 24 satellites could appear to be loads, SpaceX has really launched extra on the identical time on its Falcon 9 rockets. Final yr, the corporate launched 64 tiny satellites at the same time as 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 muse of a constellation aimed to quantity within the 1000’s of satellites.
