# Cameras in Voyager probes 2017 [closed]

Riffing off an old thread...

Analog v digital and data transmission aside, I'm wondering how images were captured in such low light at 37,000+mph. Seems like a wide open aperture and slow shutter would capture a very blurry image at that speed.

Anyone read the specs that can answer?

• Which images are you referring to? – Emilio Pisanty Sep 4 '17 at 9:51
• @EmilioPisanty the question title implies to pictures taken by the Voyager in 2017. – Communisty Sep 4 '17 at 9:59
• Neither Voyager probe has taken any pictures for a long time: more than twenty years in fact. So I am not sure what the '2017' refers to. With regards to motion blurring, you may want to consider that the objects photographed by spacecraft are usually quite a long way away. – tfb Sep 4 '17 at 10:04
• Voyager spacecraft were reprogrammable, and for its final planetary pictures, it was programmed to do a) a long exposure, and b) move the camera to always be pointing at the planet, to avoid the blur that would be present. – CDCM Sep 4 '17 at 11:09

Nevertheless, your question still applies. Voyager 1 is currently travelling, as you note, at $60\,000\:\rm{km/h}$; in 1990 it was at about 40 AU from the Sun (as opposed to 140 AU now), which turns out to make only a negligible effect on its speed. That sounds pretty fast, but keep in mind that it is imaging objects that are at astronomical distances from it: even if you keep the aperture open for an entire day, so that the spacecraft moves about 1.4 million km during the exposure, that's still about a hundred times less than the Earth-Sun distance and therefore about 4000 times less than Voyager's distance from the Sun. At solar-system length scales, even to imaging precision, Voyager hardly moved during the exposure time.
