Voyager 1 and 2 have been out there for 28 years, having been launched in 1977. In that time
"Unsurpassed image quality gave billion's of human eyes extraordinary views only vaguely hinted at using earth-bound telescopes. Jupiter was found to possess a faint ring, volcanoes were seen to erupt from Io - inmost of the four galiliean satellites. Data related to Jupiter's thermal characteristics and massive magnetic field was collected."Spinning past Saturn, Uranus, and finally Neptune ...
"They resolved stunning details of Saturn's exquisite ring system, and helped understand the role of 'shepherd moons' in holding that ring together. They revealed unresolved features on the Ringed Wonder's globe, and found surprisingly active storm systems. A ring system was discovered on Uranus too, and a large, powerful storm on distant Neptune was complete surprise. They even turned up a total of 22 new satellites. All of this at a cost of $865 million to US taxpayers."They are now on a new mission, to explore the Kuiper belt and beyond, the threshold of interstellar space. Already it has been useful. "Powerful solar storms caused a series of Coronal Mass Ejections (CMEs) during October 2003. By mid-April 2004, Voyager 2 had detected the resulting shock waves as they slowed to combine with matter in the Merged Interaction Regions outside the orbit of Pluto. Voyager 2 measured shock speed, composition, temperature, and magnetic flux. When included with data from spacecraft located nearer to the Sun (SOHO, Mars Odyssey, Ulysses, Cassini etc.), Voyager helped show how CMEs move through the Solar System."
From NASA's own Voyager webpage:
"For the past two years or so, Voyager 1 has detected phenomena unlike any encountered before in all its years of exploration. These observations and what they may infer about the approach to the termination shock have been the subject of on-going scientific debates. While some of the scientist believed that the passage past the termination shock had already begun, some of the phenomena observed were not what would have been expected. So the debate continues while even more data are being returned and analyzed. However, it is certain that the spacecraft are in a new regime of space. The observed plasma wave oscillations and increased energetic particle activity may only be the long-awaited precursor to the termination shock. If we have indeed encountered the termination shock, Voyager 1 would be the first spacecraft to enter the solar system's final frontier, a vast expanse where wind from the Sun blows hot against thin gas between the stars: interstellar space." First Hubble, now Voyager, what's next? The Mars rovers? The ongoing cost involved is chicken-feed compared with the cost, in todays dollars, of trying to reproduce the mission! If NASA must shed old programs to concentrate it's funding on the new manned space race then they should at least hand the baton to someone else who might be prepared to run with it!I wonder if this type of situation might be one where "minding the store" could be handed over to an amateur or educational organisation? What would be the hardware required? What is the current infrastructure of the "watching brief"? How many people, what qualifications, how would it be analysed, who would be interested in the output?
When you consider the popularity of amateur programs such as SETI at home and the search for comets and NEO's - could it be split up into a program that utilises many hands to make light work?
Or could some smaller university take this on as a graduate programme? Surely it would be an excellent candidate for private, state and federal grants? The article mentions "an annual cost of about $4 million a year" could this be cut back?
Perhaps it could be a combination of the amateur and professional? I'm guessing that the hardware to "hear" Voyager would be a large dish like The Parkes Observatory. Perhaps the data could then be handed on to an university or amateur organisation for analysis?
Friends, I'd love to see my tax dollars go towards that!
