Two ESA Craft To Observe Asteroid 21 Lutetia

japan_dan writes "Two ESA spacecraft will observe 21 Lutetia during Rosetta's flyby on 10 July: Rosetta from 3,160 km and Herschel from 450 million km. Herschel's PACS and SPIRE spectrometers will view Lutetia in far infrared, while Rosetta will gather data in a variety of wavelengths. Since the observations will be coordinated during and at closest approach, scientists will later be able to correlate the data to produce a map of the thermal radiation emitted by Lutetia. There are a pair of animations modelling the expected temperature distribution over Lutetia at the link. The joint observations are part of a series of 8 sessions planned in the next couple of years by Herschel scientists to study objects that will be visited by spacecraft."

Building wiring could be made out of gold instead of copper or aluminum, simply because gold has the lowest resistance of room-temperature wiring.

No it doesn't. Silver is the metal with the lowest resistance (1.58e-8 ohm-m), followed by copper (1.68e-8 ohm-m). Gold comes in third (2.44e-8 ohm-m), only slightly ahead of aluminum (2.82e-8 ohm-m).
