ViaSat-3 is a global constellation of three geostationary Ka-band communications satellites by Viasat, Inc.

The satellites are intended to provide broadband connectivity with speeds of 100-plus megabits per second to homes, business and enterprise internet users, commercial, government and business aircraft, as well as government and defense markets, maritime and oceanic enterprises in the Americas, Europe, the Middle East, Africa and Asia-Pacific.

The satellites were first announced in 2015. In February 2016, Viasat announced a partnership with Boeing Satellite Systems. For each of the three ViaSat-3 class satellites, Viasat will build the satellite payload, integrate the payload into the Boeing-provided payload module.

Boeing will provide the scalable 702 satellite platform, system integration and test, launch vehicle integration and mission operations services. Each ViaSat-3 satellite payload is being manufactured at Viasat's own manufacturing facility in Tempe, Arizona, using modular structures from Boeing Satellite Systems in El Segundo, California. The satellites are projected to have a total network capacity over 1 terabit per second.

ViaSat-3 consists of three separate satellites, each designed to provide coverage to select global regions: ViaSat-3 (Americas) will cover the Americas; ViaSat-3 (EMEA) will cover Europe, the Middle East and Africa; and ViaSat-3 (APAC) will cover the Asia-Pacific regions.

Viasat has three launch contracts, one for each ViaSat-3 class satellite. In 2016, the company announced plans to launch the first satellite with Arianespace on an Ariane 6 rocket. And in 2018, announced that the second one will be launched with United Launch Alliance on an Atlas V, and the third one with SpaceX on the Falcon Heavy.

The Falcon Heavy rocket will launch the Americas and the EMEA will be launched on an Atlas V rocket in 2023.

G-Space 1 is Gravity Space's new spacecraft with a primary mission to provide communication services for IOTs (Internet of Things).

The spacecraft is also designed to provide orbital slot reservation services (BIU) around the geosynchronous arc. It features three wideband frequency bands and will also carry an imaging system capable of imaging both the Earth and spatial bodies, as well as an experimental rendezvous and docking payload.

Falcon Heavy is designed and manufactured by SpaceX in Hawthorne, California. 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.

Lineage

SpaceX conducted Falcon Heavy's first launch on February 6th, 2018, at 3:45 PM EST. The rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk, with a dummy dubbed "Starman" in the driver's seat.

The second Falcon Heavy launch occurred on April 11th, 2019. This launch successfully launched the Arabsat-6A satellite and all three booster rockets successfully returned to Earth except but the center core subsequently fell over and was lost during transport due to heavy seas.

The third Falcon Heavy launch successfully occurred on June 25th, 2019. This mission successfully launched multiple payloads including USAF STP-2, a space memorial for Celestis, and Lightsail-2. The mission also supported the U.S. Air Force National Security Space Launch certification process for the Falcon Heavy. The side boosters were successfully recovered but the center core failed to land and was destroyed on impact with the Atlantic Ocean.

The fourth Falcon Heavy mission, USSF-44 for the U.S. Space Force, successfully launched on November 1st, 2022 from Kennedy Space Center.

The fifth Falcon Heavy mission launched USSF-67 on January 15th, 2023.

The soxth Falcon Heavy mission launched ViaSat-3 Americas on April 30th, 2023.

The seventh Falcon Heavy mission launched EchoStar 24 (Jupiter 3) on July 28th, 2023.

The eighth Falcon Heavy mission launched Psyche on October 13th, 2023.

Launch Complex 39A (LC-39A) is a historic launch site located at NASA's Kennedy Space Center in Florida. Originally constructed in the late 1960s, LC-39A was designed to support the Apollo program, including the groundbreaking Apollo 11 mission that first landed humans on the Moon in 1969. The pad also played a crucial role in launching Skylab missions and was instrumental during the Space Shuttle era, including the launch of the first Space Shuttle, Columbia, on STS-1 in 1981.

In 2014, SpaceX leased LC-39A from NASA and undertook extensive refurbishments to adapt the pad for its Falcon 9 and Falcon Heavy rockets. These upgrades involved significant modifications to the pad's infrastructure to meet the requirements of SpaceX’s rockets. Since then, LC-39A has become a vital launch site for SpaceX, supporting a range of missions including crewed flights under NASA's Commercial Crew Program.

Under SpaceX's management, LC-39A has been the site of several landmark events. It hosted the first Falcon 9 launch from the pad on March 30, 2017, and was the launch site for the historic Falcon Heavy debut on February 6, 2018, which was the most powerful rocket in operation at that time. Additionally, LC-39A was the launch site for the first crewed flight of the Crew Dragon spacecraft on May 30, 2020, marking the first crewed spaceflight from U.S. soil since the end of the Shuttle program.

Today, LC-39A remains a critical asset for SpaceX, supporting both crewed and uncrewed missions. It continues to serve as a launch site for Falcon 9 and Falcon Heavy rockets and is expected to play a central role in future missions, including those aimed at lunar exploration and beyond. The pad's rich history and ongoing significance highlight its importance in the broader context of space exploration.

SpaceX will discard all three Falcon 9 first stages, likely due to the heavy payload or the need for maximum power to achieve the correct orbit.

To further reduce weight, the rocket's landing legs and grid fins will be removed, maximizing performance.
