Context

• NASA's Voyager 1 probe, the farthest human-made object in the universe, resumes sending usable data to ground control after months of communication issues.

Details

• Since November 14, 2023, Voyager 1 had been transmitting gibberish despite receiving commands from Earth.
• In March, NASA's Jet Propulsion Laboratory identified a malfunctioning chip as the culprit and devised a coding solution compatible with the probe's 46-year-old computer system. 

Voyager 1

 Background:

• Launch: Launched on September 5, 1977, Voyager 1 made history as the first human-made spacecraft to enter the interstellar medium in 2012.
• Mission: Its primary mission was to study the outer planets of the solar system, including Jupiter and Saturn, and their moons.
• Current Location: Voyager 1 is over 15 billion miles away from Earth, with communication taking approximately 22.5 hours each way.
• Twin Spacecraft: Voyager 2, its twin, also exited the solar system in 2018.

Technical Specifications:

• Manufacturer: Built by NASA's Jet Propulsion Laboratory (JPL).
• Dimensions: Voyager 1 measures approximately 6.4 meters (21 feet) in length, including its antenna.
• Instruments: Equipped with various scientific instruments, including cameras, spectrometers, and particle detectors.

Journey Through the Solar System:

• Jupiter Flyby: Voyager 1 conducted a close flyby of Jupiter on March 5, 1979, capturing detailed images and data of the gas giant and its moons.
• Saturn Flyby: On November 12, 1980, Voyager 1 made its closest approach to Saturn, providing unprecedented insights into the planet's rings, atmosphere, and moons.
• Heliosphere Boundary Crossing: In August 2012, Voyager 1 crossed the boundary of the heliosphere, the region dominated by the Sun's influence, marking its entry into interstellar space.

Golden Records:

• Message to Extraterrestrials: Both Voyager spacecraft carry Golden Records, gold-plated copper disks containing a snapshot of life on Earth.
• Contents: The records include a map of the solar system, a uranium sample for dating purposes, and instructions for playing the record.
• Selection Process: Curated by a committee led by Carl Sagan, the records feature encoded images, music, and sounds representing Earth's culture and diversity.
