In what field(s) is Morse Code still used nowadays? Is it obsolete?

01 January 2015 1 7K Report

I know Morse code is most popular among amateur radio operators. Is it still in use in this modern era in any fields?

Dear Sohag Kabir,

yes, it seems outdated and obsolete, but it is NOT - Morse code is used in NASA's Curiosity rover on Mars for coding on its wheels:
