Watch it live here -The Falcon Heavy Demonstration Mission

From the what we’ve all wanted to do: “launch an electric car into space” department. Live video feed below.

SpaceX is counting down the launch of the Falcon Heavy demonstration mission now from Launch Complex 39A (LC-39A) (yes the one that launched men to the moon on Apollo’s SaturnV booster) at NASA’s Kennedy Space Center, Florida. The primary launch window opens at 1:30 p.m. EST, or 18:30 UTC, and closes at 4:00 p.m. EST, or 21:00 UTC. A backup launch window opens on Wednesday, February 7 at 1:30 p.m. EST, or 18:30 UTC, and closes at 4:00 p.m. EST, or 21:00 UTC.

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.

The payload for Falcon Heavy’s demonstration mission is SpaceX CEO and Lead Designer Elon Musk’s midnight-cherry Tesla Roadster. (no, really, this is not a joke)

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.

It’s important to remember that this mission is a test flight. Even if SpaceX does not complete all of the experimental milestones that are being attempted during this test, we will still be gathering critical data throughout the mission. Ultimately, a successful demonstration mission will be measured by the quality of information gathered to improve the launch vehicle.
