CAPE CANAVERAL/MERRITT ISLAND NATIONAL WILDLIFE REFUGE, FL –   The upcoming Falcon Heavy STP-2 mission nighttime launch on June 24 by SpaceX for the U.S. Air Force is the “most difficult launch ever” says SpaceX CEO and billionaire founder Elon Musk.

Liftoff of the Space Test Program-2 (STP-2) mission paid for by the Department of Defense (DoD) and managed by the U.S Air Force Space and Missile Systems Center (SMC) is now targeted for launch on June 24, 2019 at 11:30 p.m. EDT from Launch Complex 39A at the Kennedy Space Center in Florida – following the good outcome of the hold down static fire test last Wednesday.

You can get a really good feel for the complexity by watching this short video from SpaceX:

The triple stick Falcon Heavy will deliver 24 science, research, technology development and military research satellites to space into 3 separate orbits and inclinations as the second stage is fired for a record 4 separate times in another test scoping out the range of its capabilities. 

Furthermore the mission duration for the 4 second stage engine firings to enable the 24 satellite deployments is a record breaking 6 hours. 

And on top of that the STP-2 mission will also feature a breathtaking attempt by SpaceX to recover all 3 booster cores by land and by sea. 

The two side boosters will land back at the Cape 8 minutes after launch and the center core will touchdown at sea on the OCISLY droneship.

STP-2 is the first ever Falcon Heavy mission for the DOD that also includes four satellites for NASA and more for NOAA, a number of Universities, Industry and one for the Planetary Society.

“STP-2 is the government’s first launch on a SpaceX Falcon Heavy vehicle, and is one of the most challenging missions the Space and Missile Systems Center has ever launched,” said Col. Robert Bongiovi, director of the launch enterprise systems directorate at SMC at a prelaunch media briefing. 

“We’re putting 24 research and development satellites into three separate orbits, with a first-ever four engine start and burn of the second stage.”

And its not cheap either!

This only 3rd ever launch of the SpaceX Falcon Heavy generating 5 million pounds of liftoff thrust has an estimated price tag of $750 million. 

The 5 million pounds of liftoff thrust are generated from the firing of 27 Merlin 1D 1st stage engines and are the equivalent to what produced by eighteen 747 aircraft.  

This mission is using every drop of the performance of the Falcon Heavy to deploy the two dozen satellites. They fill about 1/3 of the payload fairing.

The launch window opens Monday at 11:30 p.m. EDT June 24 and extends four hours to 3:30 a.m. June 25.

In case of any delay the next launch opportunity is Tuesday, June 25 with the same launch window.

The 24 satellites have a total payload mass of 3700 kg. With the dispenser that rises to 5000 kg.

Included on the manifest are four NASA payloads investigating technologies that will help improve future spacecraft design and performance in space.

The NASA payloads aboard the Space Test Program-2 flight include:

-the Deep Space Atomic Clock for vastly improved interplanetary navigation that could change how we navigate on the Moon, to Mars and beyond,


-the Space Environment Testbeds (SET) involving four experiments to help will reveal the ways local space weather affects spacecraft hardware,


- the  Green Propellant Infusion Mission to a test cleaner and new much less toxic green propulsion system could take the small satellite revolution beyond what it is today, and


- the Enhanced Tandem Beacon Experiment involving six satellites to study irregularities in Earth’s upper atmosphere that interfere with GPS and communications signals.


NOAA along with NASA, the USAF and others are sponsoring the Constellation Observing System for Meteorology Ionosphere & Climate-2, or COSMIC-2 system– a constellation of 6 satellites. 




The Falcon Heavy first stage is comprised of three Falcon 9 cores. The center core is new and plumbed differently from the twin pair of side cores – which are recycled from the Arabsat 6A launch in mid- April.

The Falcon Heavy measures 229.6 feet (70 m) tall and 39.9 feet (12.6 m) wide with a mass of 3,125,735 lb (1,420,788 kg).
