Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
On August 21, 1993, at 01:00 UTC, three days prior to the scheduled Mars orbital insertion, there was an "inexplicable" loss of contact with Mars Observer. [22] New commands were sent every 20 minutes in the hopes that the spacecraft had drifted off course and could regain contact.
The maximum angular separation of the Earth and Moon varies considerably according to the relative distance between the Earth and Mars: it is about 25′ when Earth is closest to Mars (near inferior conjunction) but only about 3.5′ when the Earth is farthest from Mars (near superior conjunction). For comparison, the apparent diameter of the ...
