SpaceX is targeting to launch the Falcon Heavy demonstration mission on Tuesday, February 6 from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center, Florida.
The payload for the demonstration mission is SpaceX CEO and Lead Designer Elon Musk’s midnight-cherry Tesla Roadster.
The primary launch window has opened at 1:30 p.m. EST and will closes at 4:00 p.m. The launch is currently scheduled in a 15-minute window beginning at 3:45 p.m. SpaceX crew began its propellant-load procedures to fuel the rocket about 2:20 p.m.
If launch can’t take place before the window expires at 4 p.m the launch will be tried during backup launch window. The backup launch window opens on Wednesday, February 7 at 1:30 p.m. EST (18:30 UTC) and closes at 4:00 p.m. EST.
When Falcon Heavy lifts off, it will be the most powerful operational rocket in the world by a factor of two, with the ability to lift more than twice the payload of the next vehicle, at one-third the cost. Only the Saturn V moon rocket, last flown in 1973, delivered more payload to orbit.
Three cores make up the first stage of Falcon Heavy. The side cores, or boosters, are connected to the center core at its base and at the vehicle’s interstage. With a total of 27 Merlin engines, Falcon Heavy’s three cores are capable of generating more than 5 million pounds of thrust.
For this test flight, Falcon Heavy’s two side cores are both flight-proven. One launched the Thaicom 8 satellite in May 2016 and the other supported the CRS-9 mission in July 2016. SpaceX will attempt to land all three of Falcon Heavy’s first stage cores during this test. Following booster separation, Falcon Heavy’s two side cores will attempt to land at SpaceX’s Landing Zones 1 and 2 (LZ-1 and LZ-2) at Cape Canaveral Air Force Station, Florida. Falcon Heavy’s center core will attempt to land on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.
Demonstration missions like this one typically carry steel or concrete blocks as mass simulators, but SpaceX decided it would be more worthwhile to launch something fun and without irreplaceable sentimental value: a red Roadster for the red planet. Following launch, Falcon Heavy’s second stage will attempt to place the Roadster into a precessing Earth-Mars elliptical orbit around the sun.

SpaceX Falcon Heavy Launch Animation
Launch Complex 39A (LC-39A) at Kennedy Space Center, Florida
Built to support the Apollo program in the 1960s, LC-39A supported many of the Apollo missions, including the first Saturn V launch (Apollo 4), and Apollo 11, which sent the first humans to the surface of the moon.
In 2014, SpaceX signed a 20-year lease with NASA for the use of LC-39A. Since then, the company has made significant upgrades to modernize the pad’s structures and ground systems, while also preserving its important heritage. Extensive modifications to LC-39A have been made to support launches of both the Falcon 9 and Falcon Heavy launch vehicles.
