this is a translation, from a German Webside

On 31 March 2006 the AMSAT DL/IUZ team succeeded in for the first time receiving the American space probe VOYAGER 1 with the plant in Bochum. The bridged distance amounted to here 14,7 billion km and sets up a new record for Amsat DL and the IUZ Bochum. The received signal was identified clearly by the Doppler shift and by the position in the sky. Further the empfangsfrequenz was measured by means of Rubidium-Frequenznormals and compared with the data of NASA. This distance corresponds for instance to the 98-fachen distance earth sun or about the triple distance of the earth to the outermost planet Pluto. Voyager 1 is thereby furthest from the earth removed from humans built object. Hereby the efficiency of the Bochumer antenna was proven again. In all probability this is the first receipt of VOYAGER 1 of radio amateurs at all. VOYAGER 1 was started on 5 September 1977 by the American space agency NASA and conveyed the first close-ups of Jupiter and Saturn. In the year 2004 passed Voyager 1 sucked. Termination Shock region, in which the solar wind mixes itself with interstellar gas. Still today VOYAGER 1 data of the interstellar magnetic field measures. The radio amateurs taken part thereby were: Freddy de Guchteneire, ON6UG James Miller, G3RUH Hartmut Paesler, DL1YDD Achim Vollhardt, DH2VA/HB9DUN of special thanks applies for Thilo Elsner, DJ5YM of the IUZ Bochum, Roger Ludwig of the jet Propulsion Laboratory (JPL) in Pasadena/USA and the Deep space network Tracking station in Madrid/Spain.

Thanks for sharing that info Sir Ulli. Its always good to hear stuff about amateur radio stuff. :-) I unfortunately missed the opportunity to listen in to a school contact with the Space Station MIR this last week, being at work and all. Some very cool stuff there. :-) Thank you again for sharing.

I assume you mean the International Space Station?

triple distance of the earth to the outermost planet Pluto


So that would be what, about 30 AU to Neptune, and I don't recall Pluto's distance...gotta check StarryNight...sez (right now) about 31 AU. *3
So that's 93AU distant, or 12hours,24 light minutes...hmmmm....

Neat, but sure seems like spittle in the ocean, doesn't it?

He says we are talking about the MIR space station????


I hope everyone's comments are oceanic in nature.....

I hate to be a needler....but there is no more Mir space station. I'm perplexed I got a negative posting about it but facts are facts. I have not attacked ULI personally for anything and just wanted him /us/you to correct the nomenclature. Sad that that earns negative 'ratings', when one simply elaborates upon facts like I have done.

Pluto, that be the one with the pretty orbit. It varies from 30 to 50 AU.

Oh! You said currently! Whoops! Until recently it was closer than Neptune, but it has since moved further away. Can't seem to find the current distance on line, but 31 sounds like a good figure.

So I called it the wrong thing. I appologize. I don't keep up with whats flyin around. Yes I meant THE space station. Whatever it is flying around earth.

Found distances for Pluto's orbit and converted to AU's. It goes from 30 AU when inside the orbit of Neptune to just over 39 AU. Using 93 million miles as an AU.

A good site for this kind of data is NASA's Planetary Fact Sheets.

The larger figure you cite is for Pluto's average orbital radius, AKA semi-major axis, not its aphelion; according to the quick-reference table at the same site (customary unit version here), Pluto's distance from the Sun ranges from 30 to 49 AU, the average being 39 AU.

Thank you I stand corrected with better information. 4,538,000,000 miles would be roughly 49 AU
