This newly added high-gain antenna will facilitate communication between the Europa Clipper spacecraft, scheduled to launch in October 2024, and the mission controllers, even at distances of hundreds of millions of miles.
The mission of the Europa Clipper is to explore potential habitats for life on Jupiter’s ice-covered moon. On August 14, the spacecraft was provided with a crucial component for this mission: a large dish-shaped high-gain antenna.

Antenna Specifications and Roles
Spanning 10 feet (3 meters), the high-gain antenna is the most significant and noticeable among various antennas on Europa Clipper. As the spacecraft explores Europa, 444 million miles (715 million kilometers) away from Earth, this antenna will be vital to investigate the moon’s hidden ocean, which may provide an environment suitable for life.

Upon reaching Jupiter, the antenna will direct a narrowly focused radio beam towards Earth. This concentration, essential to high-gain antennas, enables the spacecraft to send potent signals to NASA’s Deep Space Network on Earth, ensuring a high-speed transmission of scientific data.
Attachment and Examination
The carefully designed dish was affixed to the spacecraft in Southern California’s NASA Jet Propulsion Laboratory, through meticulously planned stages spanning several hours.
Matthew Bray, the antenna’s designer and head engineer, confirmed that the antenna had successfully passed its individual tests. Final testing of the spacecraft will include checking the functionality of the telecom signal paths through the antenna.
Bray, stationed at the Johns Hopkins University Applied Physics Laboratory in Maryland, has been working on this antenna since 2014, making it a significant journey for both him and the technology.
The antenna underwent a series of cross-country tests and assessments in preparation for installation, including vibration and thermal vacuum tests at NASA facilities. It arrived at JPL in October 2022 and was subsequently installed on the spacecraft.
The journey to Jupiter will commence with a launch from Kennedy Space Center in October 2024.
Focused on Europa
Jordan Evans, the Clipper project manager at JPL, highlighted the high-gain antenna’s importance, describing it as a crucial element for sending science data back from Europa. The spacecraft now looks ready with its large antenna for the upcoming critical tests as it progresses toward launch.
Nine scientific instruments will be directed towards Europa, producing extensive data. These instruments will generate images to study geology, thermal readings to locate warm areas, and other measurements to explore ices, salts, organics, atmospheric gases, and surface materials.
The high-gain antenna will transmit most of this information back to Earth within 33 to 52 minutes, allowing for a significantly stronger and more substantial data transmission than previous missions, such as NASA’s Galileo probe.
On site for the installation, Simmie Berman, the radio frequency module manager at APL, along with other engineers, ensured proper mounting and integration of the antenna. The installation’s magnitude and the potential impact of the mission on human knowledge make it an extraordinary project.
The critical step of attaching the high-gain antenna to Europa Clipper has now been accomplished, and the spacecraft awaits further preparation for its remarkable journey to the outer reaches of the solar system.
About the Mission
Europa Clipper’s main scientific objective is to identify locations beneath Jupiter’s icy moon, Europa, that might harbor life. Key goals of the mission include measuring the thickness of the icy shell, investigating its composition, and characterizing its geology. This detailed exploration will contribute to the broader understanding of the astrobiological potential of worlds beyond Earth, providing insights into possible habitable environments.
Frequently Asked Questions (FAQs) about high-gain antenna
What is the purpose of NASA’s Europa Clipper mission?
The purpose of NASA’s Europa Clipper mission is to explore Jupiter’s moon, Europa, to understand its potential subsurface ocean and environment. It is designed to seek out conditions suitable for life on this ice-covered moon.
What is the role of the high-gain antenna in the Europa Clipper spacecraft?
The high-gain antenna will enable the Europa Clipper spacecraft to communicate with mission controllers hundreds of millions of miles away. It will transmit high-powered signals back to NASA’s Deep Space Network on Earth, allowing the spacecraft to send scientific data at a high rate of transmission.
When is the Europa Clipper set to launch, and what is its destination?
The Europa Clipper is scheduled to launch in October 2024, and its destination is Europa, one of Jupiter’s moons, located some 444 million miles (715 million kilometers) from Earth.
Who are the key individuals involved in the antenna’s development and installation?
Matthew Bray is the designer and lead engineer for the high-gain antenna, and he began working on it in 2014. Simmie Berman, the radio frequency module manager at APL, ensured that the antenna was properly mounted to the spacecraft.
What scientific instruments will be on the Europa Clipper, and what will they study?
The spacecraft will host nine science instruments to produce high-resolution images, thermal images, reflected infrared light, ultraviolet light readings, ice-penetrating radar, and a magnetometer. These will be used to study Europa’s geology, surface, subsurface ocean, magnetic field, ices, salts, organics, atmospheric gases, and surface materials.
How does the high-gain antenna on the Europa Clipper compare to previous antennas used in space missions?
The high-gain antenna on Europa Clipper will stream data back to Earth over the course of 33 to 52 minutes with a strength and amount of data far greater than that of NASA’s Galileo probe, which ended its eight-year Jupiter mission in 2003.

I heard abut this project at a conference, can’t believe its finally coming together. Europa in our sights, the future is here!
Anyone know where I can see live footage of the launch? This is just supercool, and i wanna see it in action!
is it true that there might be life on Europa? The high-gain antena sounds impressive but what it might find is even more exiting!
That’s a massive project! cant wait to see the results from the Europa Clipper mission. Space is just so fascinating.
My son’s so interested in this he wants to become an astronaut one day I hope this mission brings us closer to understanding the universe, Go NASA.
