    Full 37 years after they were last used, Voyager 1's secondary thrusters were fired up to orient the spacecraft more accurately towards Earth.

    Maneuvers like that are usually performed using the primary thrusters, but they started to lose efficiency over the last years, so NASA decided to try to use the secondary ones for the first time since Voyager 1's Saturn flyby in 1980, when the space probe was mere 3 years old.

    This success should enable Voyager 1 to operate more efficiently in the future and extend its lifespan by around three years.

    I wonder: Where, exactly, in interstellar space IS Voyager 1?

    141 AU away from the Sun. That is 141 times the distance between the Earth and the Sun. 141 times.

    Thank you.

    So, it's 141 x 93,000,000 miles away. That tells me how FAR away it is, but, in what direction? Is it going in a straight line? or a curved line? or what area of space is it in?

    Funnily enough, I couldn't find easily a map of Solar System with Voyager's current position. Here is the animated flight plan of the two Voyager probes and here is it's current position in the night sky. There is also an app by NASA that enables some kind of tracking, but I haven't tried it.

    EDIT: Here's a map! :)

    EDIT: Actually, that map is 6 years old. :( It was really far outside Pluto's orbit even then though!

    On this page you can see some information about both Voyager probes.

    https://voyager.jpl.nasa.gov/mission/status/

    You need to install the app to see the trajectories but it doesn't show other star systems so you can find out which ones they're heading to.
