When did NASA start working on the Voyager?
In the 1960s, a Grand Tour to study the outer planets was proposed which prompted NASA to begin work on a mission in the early 1970s. Information gathered by the Pioneer 10 spacecraft helped Voyager's engineers design Voyager to cope more effectively with the intense radiation environment around Jupiter.
How many instruments are in Voyager 1?
Voyager 1 was constructed by the Jet Propulsion Laboratory. It has 16 hydrazine thrusters, three-axis stabilization gyroscopes, and referencing instruments to keep the probe's radio antenna pointed toward Earth. Collectively, these instruments are part of the Attitude and Articulation Control Subsystem (AACS), along with redundant units of most instruments and 8 backup thrusters. The spacecraft also included 11 scientific instruments to study celestial objects such as planets as it travels through space.
About the mission
Voyager 1 reached interstellar space in August 2012 and is the most distant human-made object in existence. Launched just shortly after its twin spacecraft, Voyager 2, in 1977, Voyager 1 explored the Jovian and Saturnian systems discovering new moons, active volcanoes and a wealth of data about the outer solar system.
Mission Highlights
September 2013: After intensive analysis, mission scientists determine that Voyager 1 reached interstellar space in August 2012.
How did Voyager work?
The Voyager mission was designed to take advantage of a rare geometric arrangement of the outer planets in the late 1970s and the 1980s which allowed for a four-planet tour for a minimum of propellant and trip time. This layout of Jupiter, Saturn, Uranus and Neptune, which occurs about every 175 years, allows a spacecraft on a particular flight path to swing from one planet to the next without the need for large onboard propulsion systems. The flyby of each planet bends the spacecraft's flight path and increases its velocity enough to deliver it to the next destination. Using this "gravity assist" technique, first demonstrated with NASA's Mariner 10 Venus/Mercury mission in 1973-74, the flight time to Neptune was reduced from 30 years to 12.
Where was the Voyager 1 launched?
The twin spacecraft Voyager 1 and Voyager 2 were launched by NASA in separate months in the summer of 1977 from Cape Canaveral, Florida. As originally designed, the Voyagers were to conduct closeup studies of Jupiter and Saturn, Saturn's rings, and the larger moons of the two planets.
What was the Voyager mission?

When did Voyager 2 encounter Uranus?
Voyager 2 encountered Uranus on January 24, 1986, returning detailed photos and other data on the planet, its moons, magnetic field and dark rings. Voyager 1, meanwhile, continues to press outward, conducting studies of interplanetary space.
When did the Voyager 1 come to Jupiter?
JUPITER Voyager 1 made its closest approach to Jupiter on March 5, 1979, and Voyager 2 followed with its closest approach occurring on July 9, 1979. The first spacecraft flew within 277,400 kilometers (172,368 miles) of the planet's cloud tops, and Voyager 2 came within 650,180 kilometers (404,003 miles).
What planets did Voyager 1 find?
Voyager 1 found the moon Mimas scarred with a crater so huge that the impact that caused it nearly broke the satellite apart. Saturn's magnetic field is smaller than Jupiter's, extending only one or two million kilometers. The axis of the field is almost perfectly aligned with the rotation axis of the planet.
What is Jupiter made of?
Jupiter is the largest planet in the solar system, composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor, traces of other compounds and a core of melted rock and ice. Colorful latitudinal bands and atmospheric clouds and storms illustrate Jupiter's dynamic weather system.
How long has Voyager 1 been flying?
The spacecraft, which has been flying for 40 years, relies on small devices called thrusters ...
What is Voyager 1 thrusters?
Since 2014, engineers have noticed that the thrusters Voyager 1 has been using to orient the spacecraft, called "attitude control thrusters," have been degrading. Over time, the thrusters require more puffs to give off the same amount of energy. At 13 billion miles from Earth, there's no mechanic shop nearby to get a tune-up.
How does Voyager work?
The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. These thrusters fire in tiny pulses, or "puffs," lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet. Now, the Voyager team is able to use a set ...
Is Voyager 2 going to enter space?
The attitude control thrusters currently used for Voyager 2 are not yet as degraded as Voyager 1's, however. Voyager 2 is also on course to enter interstellar space, likely within the next few years. The Voyager spacecraft were built by JPL, which continues to operate both. JPL is a division of Caltech in Pasadena.
Who built the Voyager spacecraft?

How has the flu been affected by the lack of people getting it?
I've heard about how only around 1k people got the flu in 2020, and I'm curious if this has had any effects on it as far as we know?
Why do vaccines provide longer immunity from a virus than natural infection?
I know that the antibodies released by the B cells in the secondary infection will be more specific to the deactivation of the virus for the vaccine compared to natural infection and other advantages like that.
What protocol (s) does NASA use to communicate long distances?
I am looking at https://mars.nasa.gov/mars2020/spacecraft/rover/communications/ which talks about how the rover communicated with Earth, which is through the orbiter.
