| Voyager 1 is the farthest man-made object from Earth.

| TL;DR - Voyager is sending back bad data, they're working on it.

| Voyager 1 is so far away that it takes 22.5 hours for commands

| must wait 45 hours to receive a response.

| I'm guessing "hotfix" commits don't exist in this domain
| bee_rider wrote:
| I guess it is nitpicking, but I hate the word choice they've

| The use of "additionally" is weird here. A full roundtrip is 45
| hours. It doesn't take 22.5 + 45 hours to receive a response.
| 45 = 22.5 + 22.5.

| This is an absolutely terrible headline. Voyager is communicating

| communicating with Earth.
| SkyPuncher wrote:
| No, it's an accurate headline for the general population.
|
| It's sending nothing useful.
| mholt wrote:
| The headline doesn't say _useful_ though. Just that it
| stopped communicating, which is false.
| h2odragon wrote:
| "im still here" is useful.

| Voyager 1 has a large 12-foot diameter directional radio

| There are radio antennas across the Earth listening to its very
| weak signal.
