The first test flight of Falcon Heavy is set for this afternoon at 1:30 PM ET from Launch Complex 39A at Kennedy Space Center in Florida.

The Falcon Heavy rocket is essentially the same as it’s workhorse Falcon 9 rocket with two additional boosters attached to the sides. This triples the thrust at liftoff and means the Heavy will be able to lift a payload of up to 140,000 pounds – essentially double the payload of any other.

The rocket is launching from the historic Pad 39A at the Kennedy Space Center. This is the same launch pad that used by Apollo 11 in 1969, the first mission that took astronauts to the moon, and the first space shuttle launch in 1981.

SpaceX will broadcast the launch on its website beginning at 1:10 p.m. Eastern (18:10 Hrs. UTC), and on their YouTube channel – here.

Today’s launch window is from 1:30 p.m. to 4:00 p.m. Eastern. The weather forecast is for favourable conditions. If the weather doesn’t changes, or if some technical glitch postpones the launch, SpaceX will try again on Wednesday.
