The Voyager program is an American scientific program that employs two interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment to explore the two gas giants Jupiter and Saturn and potentially also the ice giants, Uranus and Neptune - to fly near them while collecting data for ...
Voyager 1 is so far away that it takes 22.5 hours for commands sent from Earth to reach the spacecraft. Additionally, the team must wait 45 hours to receive a response. Keeping the Voyager probes ...
In August 2023, the mission team used a long-shot “shout” technique to restore communications with Voyager 2 after a command inadvertently oriented the spacecraft’s antenna in the wrong ...
How the Voyager probes keep going. Voyager 1 is so far away that it takes 22.5 hours for commands sent from Earth to reach the spacecraft. Additionally, the team must wait 45 hours to receive a ...
The 3.7 m (12 ft) diameter high gain dish antenna used on the Voyager craft. Voyager 1 was built by the Jet Propulsion Laboratory (JPL). It has 16 hydrazine thrusters, three-axis stabilization gyroscopes, and referencing instruments to keep the probe's radio antenna pointed toward Earth.
The probe entered the interstellar medium on November 5, 2018, at a distance of 119.7 AU (11.1 billion mi; 17.9 billion km) from the Sun [5] and moving at a velocity of 15.341 km/s (34,320 mph) [4] relative to the Sun. Voyager 2 has left the Sun's heliosphere and is traveling through the interstellar medium, though still inside the Solar System ...
The Voyager 1 spacecraft is functioning normally again after the aging probe’s dwindling power supply triggered a communications blackout. It’s one of several challenges faced by the ...
Voyager 1 is a space probe launched by NASA on September 5, 1977. At a distance of about 162.755 AU (2.435 × 10 10 km) as of 4 February 2025, [7] [8] it is the farthest manmade object from Earth. [9] It was later estimated that Voyager 1 crossed the termination shock on December 16, 2004 at a distance of 94 AU from the Sun. [10] [11]
