CAPE CANAVERAL, Fla. (AP) — A NASA rover on Mars has fallen silent as a gigantic dust storm envelops the planet and blots out the sun.

Flight controllers tried late Tuesday night to contact Opportunity, but the rover did not respond. The storm has been growing since the end of May and now covers one-quarter of the planet.
