What is JUPITER-3?

July 27, 2023

SpaceX, led by visionary entrepreneur Elon Musk, is set to make history once again by launching the world’s largest private satellite to space on July 27. The satellite, named JUPITER-3 and developed by Maxar Technologies, is a breakthrough in the field of communications satellites, boasting impressive size and cutting-edge technology.

SpaceX’s Falcon Heavy Rocket

SpaceX’s Falcon Heavy rocket, known for its triple-booster design, will carry the JUPITER-3 satellite into space. This upcoming launch will signify the Falcon Heavy’s seventh mission, gaining widespread attention since its inaugural flight in 2018. The rocket has proven to be a reliable workhorse in the aerospace industry.

Meet JUPITER-3: The Largest Commercial Communications Satellite

JUPITER-3 is not just any ordinary satellite; it is the largest commercial communications satellite ever built. Developed by Maxar Technologies in Palo Alto, California, this satellite represents a major leap in satellite technology.

Impressive Size and Capabilities

Upon complete deployment, the JUPITER-3 satellite’s dimensions will resemble the wingspan of a commercial airliner, ranging from 130 to 160 feet (approximately 40 to 50 meters). Beyond its size, what sets JUPITER-3 apart are its advanced technological features and capabilities.

Enhancing Satellite Fleet Capacity

One of the primary aims of JUPITER-3 is to double the capacity of Maxar Technologies’ satellite fleet with an additional 500 Gbps. This substantial increase in capacity will enable the company to better serve customers, especially in regions where cable and fiber connectivity are unavailable or unreliable, such as in remote areas.

Wide-Ranging Applications

The JUPITER-3 satellite will cater to various communication needs. Its applications include supporting in-flight Wi-Fi, maritime connections, enterprise networks, backhaul for Mobile Network Operators (MNOs), and Community Wi-Fi solutions across North and South America.

Technological Advances and Testing

JUPITER-3 features an updated technological architecture that allows for the miniaturization of electronics. It includes solid-state amplifiers and enhanced antenna efficiency. The satellite underwent rigorous vibration and temperature testing, including Thermal Vacuum Testing, to ensure its resilience in the extreme conditions of space.
