Discussion Overview

The discussion revolves around identifying a specific NASA mission that involved deploying a satellite with two long wires extended in opposite directions, which were intended to generate electricity from charged particles in the Van Allen belts. Participants seek to clarify details about the mission's name, success, and historical context.

Discussion Character

  • Exploratory, Technical explanation, Historical

Main Points Raised

  • One participant recalls a mission involving a satellite with long wires that generated electricity from charged particles in the Van Allen belts but is unsure of the mission's name or success.
  • Another participant suggests a lead to a 1996 mission known as the "Tethered Satellite System," which involved a wire connecting a space shuttle to a satellite and generating electricity.
  • A different participant mentions a shuttle mission that involved a yo-yo effect with the tether, noting that the first attempt failed due to a jammed cable, while the second attempt did not yield significant results.
  • One participant references Hannes Alfven, a physicist who proposed the concept of electric power generation using electric and magnetic fields in space, indicating the historical background of the idea.

Areas of Agreement / Disagreement

Participants express uncertainty about the specific mission being discussed, with multiple competing views regarding its name and details. The discussion remains unresolved regarding the exact identification of the mission.

Contextual Notes

There are limitations in the information provided, including missing details about the mission's launch status, success, and the specific scientific principles involved in the electricity generation process.

Hi all,

I'm trying to find information on this one mission (NASA AFAIK)...

They deployed a satellite which had two long wires extended in opposite directions.

The wires acted as a conducting path for charged particles in the Van-Allen belts and their motion generated electricity in the satellite main body.

I remember hearing about it, but I don't know if the mission was launched, was successful, ITS NAME, etc.

Any information would be grately appreciated.

Is that the shuttle mission where they played with a yo-yo? I think they did it twice - the first time it didn't work because the cable jammed. So they sent it up again and the second time it deployed but didn't do much of interest.

I think both missions happened within the past 2 years.

edit: too late...
 
Thanks all!
 
one more thing (no thanks required!)
the scheme or something like it was originally
thought up by Hannes Alfven.

Hannes Alfven (1908-1995) Swedish physicist who
won Nobel in 1970, proposed electric power generation using the electric and magnetic fields in space way back, maybe as early as the 1970s, possibly even earlier. He did creative work in many fields

Just to indicate the kind of man----around 1960 he
predicted the large filamentary structure of the
universe---the sort of cob-webby pattern of clusters of
galaxies---that
was discovered 30 years later
