"Overall science instrument mass was 57.6 kg" et al. The spacecraft has not changed its shape or mass, so should this be present tense? Although they do not function, they are still in orbit around the sun. As far as anyone knows, they have not been destroyed. —Preceding unsigned comment added by 188.8.131.52 (talk • contribs) 16:45, 29 March 2006
A good question. I think it's past tense because the spacecraft is essentially dead and much of this article refers to it in its operating state.--Lendorien 16:13, 16 August 2007 (UTC)
I've added a document which discusses JPL support for tracking the spacecraft after the Mars encounter until about December 1970 when the attitude control gas was exhausted. During this period some additional photography was taken and distance determination experiments carried out. It might be worthwhile to mention this in some form in the article.
