True, but sometimes I get a bit concerned when I read stuff like "Voyager 1’s instruments indicated at (sic) the solar wind suddenly dropped by a factor of 1,000, to the point where it was virtually undetectable. This transition happened extremely fast, taking roughly a few days."
It always crosses my mind that it could just be the instruments screwing up. Maybe they're not reading any solar wind because the sensor that measures solar wind has finally died. It took a few days, but now it's barely picking up anything.
I don't think that's the case here, since they go on to point out some other things that are consistent with this inconsistency (?) but you never know...
