Yes, EETA 79001 is a meteorite because it landed on Earth.  One of the Mars rovers
found a rock named "Bounced Rock" that had a very close match to EETA 79001. 
However, "Bounced Rock"is not a meteorite - it is a native Mars rock.  
EETA 79001 is a Mars meteorite because it originated from Mars, but was 
found in the Antarctic. You do have to distinquish between a Mars meteorite, and a
meteorite found on Mars. They are not the same thing.

The iron meteorite nicknamed "Heat Shield Rock" is the first confirmed 
meteorite found on Mars.

In summary:

EETA 79001         - Mars meteorite found in the Antarctic
"Bounced Rock"     - Mars rock
"Heat Shield Rock" - Meteorite found on Mars
