Two Soyuz flights are scheduled for Thursday April 4 and the second flight ever of a SpaceX Falcon Heavy is planned for April 7.

The Soyuz flights will take off from two different locations. The first, which is scheduled for 11:01:35 UTC (07:01:35 EDT), is of a Soyuz-2.1a from the Baikonur Cosmodrome in Kazakhstan. According to SpaceFlightNow, it carries "several tons of fuel, food and supplies for the space station and its six-person crew."

The second Soyuz flight (of a Soyuz 2-1b) is scheduled for a 16:30:37 UTC (12:30:37 EDT) launch from the Guiana Space Center on the northeast coast of South America. It carries four broadband satellites for O3b Networks "which provides broadband service to developing countries."

The Falcon Heavy (FH) has flown only once before (on February 6, 2018) when it sent Elon Musk's Tesla Roadster into an orbit that extended past Mars' orbit. The FH is comprised of 3 SpaceX Block 5 cores, each of which has 9 Merlin engines.

The upcoming Falcon Heavy launch is scheduled for April 7th/8th (launch window: 22:36-00:35 UTC). That works out to 18:36-20:35 EDT on April 7th. The flight "will launch the Arabsat 6A communications satellite for Arabsat of Saudi Arabia. Arabsat 6A will provide Ku-band and Ka-band communications coverage over the Middle East and North Africa regions, as well as a footprint in South Africa."

Breaking News: Falcon Heavy Maiden Launch Successful (Mostly) 103 comments

Update: Launch seems to have been successful. The two side boosters landed nearly simultaneously. Footage from the drone ship was cut off. The car made it into space; but the third stage will need to coast through the Van Allen radiation belts for around six hours before it makes the final burn for trans-Mars injection.

Update 2: The middle booster of SpaceX's Falcon Heavy rocket failed to land on its drone ship
Falcon Heavy Post-Launch Media Briefing - Megathread

SpaceX's newest rocket, the Falcon Heavy, is set to be launched at around 1:30 PM EST (6:30 PM UTC) today. The launch window extends to 4:00 PM EST (9:00 PM UTC).

SpaceX will attempt to recover all three boosters during the launch. The two previously-flown side boosters will attempt to land nearly simultaneously at Cape Canaveral Air Force Station's Landing Zones 1 and 2. The center core will attempt to land on a drone barge hundreds of miles off the coast of Florida.

The dummy payload for the Falcon Heavy is Elon Musk's personal 2008 Tesla Roadster. It is carrying a mannequin wearing SpaceX's space suit flight suit that will be used when the company begins to send astronauts to the International Space Station. The car will be launched into a heliocentric orbit that will bring it close to Mars (and back near Earth) periodically, and is equipped with three cameras. Its stereo system will be playing David Bowie's Space Oddity.

If the launch is successful, the Falcon Heavy could be flown within the next 3 to 6 months for a customer such as the U.S. Air Force, Arabsat, Inmarsat, or ViaSat.

Falcon Heavy will be capable of launching 63,800 kg to low-Earth orbit (LEO), 26,700 kg to geosynchronous transfer orbit (GTO), 16,800 kg to Mars, or 3,500 kg to Pluto (New Horizons was 478 kg). It will supplant the Delta IV Heavy, which is capable of launching 28,790 kg to LEO or 14,220 kg to GTO. Space Launch System Block 1 will be capable of launching 70,000 kg to LEO (Block 1B: 105,000 kg to LEO, Block 2: 130,000 kg to LEO).

Musk has suggested that an additional two side boosters could be added to Falcon Heavy (perpendicularly?) to make a "Falcon Super Heavy" with even more thrust. This may not happen if SpaceX decides to focus on the BFR instead, which as planned would be able to launch 150,000 kg to LEO while being fully reusable and potentially cheaper than the Falcon 9 (or capable of launching 250,000 kg to LEO in expendable mode).

SpaceX Falcon Heavy Block 5 Launch - Postponed: 6:35pm EDT Thursday (2019-04-12 22:35 UTC) [UPDATE2] 28 comments

[Update #2] (2019-04-10 7:30pm EDT (23:30 UTC))

This launch has been scrubbed until tomorrow. :

"Standing down from today’s Falcon Heavy launch attempt; next opportunity is tomorrow, April 11."

New launch window is: "Thursday, April 11 at 6:35 p.m. EDT, or 22:35 UTC, and closes at 8:31 p.m. EDT, or 00:31 UTC on Friday, April 12"

[Update #1] (2019-04-10 8:40pm EDT (22:40 UTC)):

It appears the launch has been delayed 85 minutes from 6:35pm EDT (22:35 UTC) until 8:00pm EDT (00:00 UTC on 2019-04-11); see the tweet:

Falcon Heavy and Arabsat-6A are vertical on Launch Complex 39A. Currently targeting liftoff at 8:00 p.m. EDT; monitoring upper-level winds that could push us to the end of the window (8:32 p.m. EDT)

Also noted on SpaceX's webcast page:

SpaceX is targeting Wednesday, April 10 for a Falcon Heavy launch of the Arabsat-6A satellite from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Liftoff is targeted for 8:00 p.m. EDT, or 00:00 UTC on April 11, and the launch window closes at 8:32 p.m. EDT, or 00:32 UTC on April 11. A backup launch window opens on Thursday, April 11 at 6:35 p.m. EDT, or 22:35 UTC, and closes at 8:31 p.m. EDT, or 00:31 UTC on Friday, April 12. The satellite will be deployed approximately 34 minutes after liftoff.

Following booster separation, Falcon Heavy’s two side boosters will attempt to land at SpaceX’s Landing Zones 1 and 2 (LZ-1 and LZ-2) at Cape Canaveral Air Force Station in 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.

You can watch a webcast of the launch below, which will start about 20 minutes before liftoff, and find out more about the mission in our press kit (pdf).

Original story follows.

For only the second time ever, and the first time with a commercial payload (Arabsat-6A), SpaceX is planning to launch its Falcon Heavy (FH) rocket today. The launch was rescheduled from April 7th and April 9th. The FH is currently the most powerful rocket in the world. According to Wikipedia, the:

Falcon Heavy is a partially reusable heavy-lift launch vehicle designed and manufactured by SpaceX. It is derived from the Falcon 9 vehicle and consists of a strengthened Falcon 9 first stage as a central core with two additional first stages as strap-on boosters. Falcon Heavy has the highest payload capacity of any currently operational launch vehicle, and the fourth-highest capacity of any rocket ever built, trailing the American Saturn V and the Soviet Energia and N1.

SpaceX conducted Falcon Heavy's maiden launch on February 6, 2018, at 3:45 p.m. EST (20:45 UTC). The rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk, as a dummy payload.

From an article at Teslarati, SpaceX to Livestream Falcon Heavy Block 5 Launch Debut Today:

SpaceX is half a day away from the planned launch debut of Falcon Heavy Block 5, a milestone that will also be the rocket's second launch ever and first mission with a commercial payload.

First and foremost, Falcon Heavy's job is to safely place the Saudi Arabian communications satellite Arabsat 6A into a high-energy geostationary transfer orbit (GTO) more than 35,000 km (~22,000 mi) above Earth's surface. Despite the satellite weighing no less than 6000 kg (13,200 lb), Falcon Heavy will still have enough latent performance to attempt the recovery of all three of its new Block 5 boosters. With any luck, this will hopefully return SpaceX's East Coast landing zones (LZ-1 and LZ-2) to successful operations after an anomaly in December 2018 caused Falcon 9 B1051 to landing a mile or so offshore.

[...] This time around, Falcon Heavy will be made entirely out of Block 5 hardware, including three new boosters (likely B1052, B1053, and B1055), a Block 5 upper stage with a Merlin Vacuum engine, and a recovery-optimized "Version 2" payload fairing. Altogether, Falcon Heavy likely weighs upwards of 80,000 kg (175,000 lb) empty and more than 1,420 metric tons (3,125,000 lb) when fully fueled. At liftoff, the Falcon Heavy Block 5 rocket's 27 Merlin 1D engines are expected to produce no less than 5.1 million pounds (~2300 mT/23,000 kN) of thrust at full throttle, but that figure could rise as high as 5.6 million pounds (2550 mT/25,500 kN) of thrust depending on how one interprets rather vague official numbers from CEO Elon Musk.

    Not content with having an application to spy on their wives and daughters and cancel their passport at a click of a button [the-levant.com] they now want 34/7/365 visuals to track people down. Well done for helping them SpaceX.

      That's a Falcon Heavy I wouldn't mind to explode in flight.

      Arabsat-6A is a telecom satellite, not a spy satellite. It was built by Lockheed Martin.

        Even if it was a spy satellite, what's the point of 24/365 visual on women who are always wearing burquas (and with a male relative/guardian) ?
