This page shows you the set of Mars images taken in 2001. The Mars comes the closest to the Earth on June 22, its apparent diameter will exceed 20 arc seconds. The Mars closes to the Earth every 26 months, and next approach in August 2003, the Mars will have the closest approach to the Earth in 21st century. This year's return of Mars can be said a preliminary skirmish of the approach in 2003, the observing season will continue until autumn of this year.
  Added a postscript on Jul 9, 2001
  It's reported that the large-scaled sand storm occurred on Mars in July 2001 and the storm is covering major features on Mars. Images of July 3 and 4 show you very flat appearences of Mars different from those before June.
