Nobody highlighted this and I didn't find any comment from Nasa/Voyager sites.
On August,11 the intrepid Voyager-1 probe will reach 14.960 billion Km from the Sun, one hundred times the average Earth-Sun distance! This event will be followed, after 16 days, by the 100AU from Earth reach. From astrophysical standpoint, first event is the most important but, I think, most people will be emotionally hit from the second one. So I would like to start a poll on this. -------------------- I always think before posting! - Marco -

Dilo,
I understand you use Nasa space calculator but, does the difference goes as 100-1 for Earth distance or do you consider the EXACT position of Earth on August 25th? You know, the difference could be + or - 1 UA depending where's the Earth on its orbit. By the way, August 25th is prety close to celebrate the 17th anniversary of Voyager II fly-by of Neptune. By the way, if you open up a pool like arrival of Oppy at VC or Eagle, my bets are 100 UA from SUN first Can you tell us when the round trip signal will need 24 hours? -------------------- |

Climber, using Nasa space SIMulator is pretty easy to know the exact moment of both events, withut additional calculation... moreover, as you can see from following snapshot, Earth will be going farther from Voyager at this epoch, so no risk of "multiple" 100AU events!
We passed the time for 24hrs signal round trip (go and forth) in Nov 2002; if you are asking about the time when round trip signal will need 24 hours to reach Voyager (173 AU), this should happens at the beginning of 2027 but, unfortunately, at this epoch Voyager will be dead. -------------------- I always think before posting! - Marco -
