Experts from the United States and other countries, astronomy fans and other curious people are following the progress of a vehicle that is scheduled to land on Mars in just a few days.
It includes a rover named Curiosity that was launched last year and should be arriving on the red planet at the beginning of August.
The Mars Science Laboratory's mission is part of NASA's Mars Exploration Program and involves the participation and collaboration of many organizations and people.
