Would be cool to see how often they communicate, and what data is exchanged. Also, what bandwidth and the time it takes to arrive back here.

- cygx 6y agoAlso [...] the time it takes to arrive back here For reference: Voyager 1, interstellar space 21 lighthours Perseverance, Mars surface 12 lightminutes Artemis, lunar orbit 1.2 lightseconds
- spzb 6y agoAren't those measures of distance?
- gberger 6y agoYes, but the data travels at approximately the speed of light, so you can just drop the "light" unit in front of the time units
- spzb 6y agoBut where’s the fun of pedantry in that?
- argvargc 6y agoDelete "light" and it's the answer.
- emayljames 6y agoYeah, it takes me 2 trainhours to get to work.

- cygx 6y agoSure, but conversion to travel time is trivial given a signal velocity of c. Or just assume a 'natural' system of units where c=1 :p
- gspr 6y agoMaybe some of what you desire can be found here? https://eyes.nasa.gov/dsn/dsn.html https://eyes.nasa.gov/dsn/dsn.html
- shagie 6y agoAnd occasionally... you get a glimpse of something neat... like dish 43 getting data from VGR2. https://i.imgur.com/ZVAnt03.png https://i.imgur.com/ZVAnt03.png The downlink is 160 b/s at -154.54 dBm (as I type this - might have been different in the screen shot)... and then compare that to other data feeds on other dishes.
