It was sad to see it go. Does anyone know the tune that was played in the video? It was so touching and appropriate to the Jules Verne's final moments. This was so cool. It was sad to see it go.

Rest easy. As every europeeing knows - US 'yanks' are full of it ... and we take it with us .... all that crap dumped by the JV was from visiting ESA asstronaughts. Lighten up 'francis' ....

Power supply is crucial to the operation of the ISS. Since November 2000 the photovoltaic (PV) module supports electric power demands of the station and its three member crew: "Existing electrical supplies primarily are being used to run oxygen generation, carbon dioxide removal, water production and other systems essential to keeping the station crew alive in the deadly vacuum of space."[1] In this context a panorama snapshot of the ISS by the STS-124 shuttle crew reveals something amazing.[2] On the picture one can see the ATV docked at the same time on the Zvezda aft port, a Progress M-64 on the Zarya nadir port and behind it a Soyuz TMA. The three ships are provided with altogether 8 solar panels with an estimated total area of more than 30 square meters (nearly 10 percent of the ISS PV module area).[3],[4] The problem is that these solar arrays were not designed for further use. Neither in their quality nor in the way how they were mounted. These valuable material is declared as "space junk". It is agreed to be burned up in the atmosphere. One can see clearly that "space junk" is not necessarilly distributed all over the orbit (as you assumed in an earlier commend, DaveS). No, it is directly at the front door of the ISS. It is in reach of an EVA and of the robotic arm. There are regularly flights of Progress and Soyuz to the ISS (Progress meanwhile about 25 times). They all arrive with additional potential power supply. Meanwhile there was more solar panel "junk" burned up than the whole PV module comprisses (375 m²). I don't know what their electricity bill is, but I guess it could be less.

Why not take it apart or collapse it down before returning it by space shuttle. They do come back empty don't they. It does seem to be an terrible waste of material.

There's not a lot of ways around it, but, It seems a shameful waste of materials and resource in an age where I recycle my cardboard, glass and plastics etc ..

What WOULD you have them do with it? Let go and allowed to orbit? Eventually it would have come down anyway, and in an uncontrolled reentry, just as much pollution, and much more danger. And while it was doing that, it would make yet another piece of space debris, which place astronauts, cosmonauts and taikonauts in danger, not to mention the many commercial, scientific, and government satellites. Kept attached to the ISS, it not only would add to the mass of the station, making additional orbital maneuvers use more fuel, it would take up a docking port, that may be needed in an emergency. Pick your option. Besides, this was the ESA who did this, not the 'bloody yanks'. David, quick question. What WOULD you have them do with it?

It was ESA's mission plan all along to perform a controlled reentry of their vehicle. Check your facts before going off. As for European members of ESA, congrats to all for the fine, flawless first mission of the Jules Verne. I'm sure many American space enthusiasts, myself included, closely followed this historic mission. For such a complex vehicle to perform such a demanding mission(its' first!) speaks highly of Europe's expertise in aeronautics. @ David, Jules Verne was built and launched by the European Space Agency, as mentioned in the article( did you bother to read it?).
