Scientific Data:
* Plasma Waves: Detecting and analyzing the electromagnetic waves present in the interstellar medium, giving insight into the structure and composition of the space between stars.
* Cosmic Rays: Measuring the energy and composition of high-energy particles from the Sun and other sources in the galaxy, providing data on galactic evolution and activity.
* Magnetic Fields: Measuring the strength and direction of magnetic fields in the heliosphere and interstellar space, revealing the interaction between the Sun's magnetic field and the galactic environment.
* Dust Particles: Detecting and analyzing dust grains encountered along their trajectory, offering clues about the composition and formation of planetary systems.
* Radio Waves: Listening for and studying radio emissions from planets, moons, and other celestial objects within the solar system.
* Images: Though limited, Voyager 1 and 2 still transmit occasional low-resolution images of distant objects.
Telemetry Data:
* Spacecraft Health: Sending information about the probes' status, including their power levels, temperature, and the functionality of various subsystems.
* Engineering Data: Reporting on the performance of their instruments and systems, helping engineers to understand and troubleshoot any issues.
Other Information:
* Golden Record: The Voyager probes carry a "Golden Record," a time capsule containing sounds and images representing humanity and Earth's diversity, intended for any potential alien civilization that might intercept the probes.
Transmission Methods:
* Deep Space Network (DSN): The Voyager probes communicate with Earth through NASA's DSN, a network of giant radio antennas located around the globe.
* X-band: The Voyager probes use the X-band radio frequency to transmit data back to Earth.
Current Status:
* Voyager 1 and 2 continue to transmit data to Earth, despite their incredible distance.
* The data they send is crucial for understanding the solar system, our galaxy, and the vastness of space.
The information gathered by the Voyager space probes has revolutionized our understanding of the solar system and beyond, and continues to inspire new discoveries.
