Status of Japan’s Mars Explorer “NOZOMI” JAXA

Some of you might have read a report of a newspaper; “NOZOMI, Japanese made Mars exploration probe is to collide with Mars”. But this description is not correct. The truth is that “NOZOMI” will, if going as it is, approach Mars on December 14 by 894km passing above Martian surface at its closest approach, but there would not be excluded a theoretical possibility of colliding with Mars by more or less one percent, if we take the error of orbit determination into account.
