SpaceX Falcon Heavy Launch Time & Stream

SpaceX's Falcon Heavy is by far the most powerful operational rocket in the world.

While the launch was initially planned for 9 April, weather on the day wasn't conducive for the launch, which has now been moved to 10 April at 10.35 pm GMT (11 April 4.05 am IST). Planetary scientists have also said the rocket's mere existence has put price pressure on other boosters typically used for deep space probes. Forecasters expect an 80-percent chance of good weather.

This might be the second flight for SpaceX's Falcon Heavy rocket but it's still a major "first" for the company in a number of ways. Ranging from multiple sonic booms that will be audible for miles up and down the Florida coast and the potential for a spectacular Florida sunset as a backdrop, Falcon Heavy's second launch will be an event worth watching.

This time around SpaceX has a paying customer to please. (6,000 kilograms) Arabsat-6A for the Saudi Arabian satellite communications company Arabsat.

Here's the mission timeline for today, as shared by SpaceX for after the launch.

After launch and first stage separation, Falcon Heavy's two side boosters will attempt to land back at SpaceX's Landing Zones 1 and 2 at Cape Canaveral Air Force Station, while the center core will attempt to land on the Of Course I Still Love You drone ship in the Atlantic Ocean. The launch window opens at 6:35 p.m. ET on Wednesday (22:35 UTC) and closes at 8:32 p.m. (00:32 UTC on Thursday). A standard Falcon Heavy launch costs $90 million, according to the company's website, compared to $62 million for the Falcon 9.


SpaceX wants to compete with its arch rival in the lucrative business of launching ultra-heavy satellites into space.

The Falcon Heavy's twin boosters made a simultaneous landing on pads at Cape Canaveral successfully during the test flight a year ago. Whenever possible, SpaceX plans to launch at lower speeds so they can land and possibly reuse the boosters that make up Falcon Heavy. The true test will happen tomorrow, if Falcon Heavy cannot only launch but also land its three boosters.

That was back when SpaceX was still expected to test Falcon Heavy later that same year. But the middle booster missed a seaborne platform it was created to land on, and instead splashed into the ocean.

The satellite SpaceX will launch on Wednesday will update satellite coverage for Arabsat, which is based in Riyadh and delivers hundreds of television channels and radio stations to homes across the Middle East and North Africa.

Though Falcon Heavy's inaugural launch ultimately went off without a hitch, SpaceX will now have to repeat that success with the added risk of carrying a multimillion dollar satellite.
