 :"''2001 Mars Odyssey is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet. The opportunity to go to Mars comes around every 26 months, when the alignment of Earth and Mars in their orbits around the sun allows spacecraft to travel between the two planets with the least amount of energy. 2001 Mars Odyssey launched on April 7, 2001, and arrived at Mars on October 24, 2001, 0230 Universal Time (October 23, 7:30 pm PDT/ 10:30 EDT).''" - [http://mars.jpl.nasa.gov/odyssey/overview/ Mission website].

These salt deposits occur in the middle to low latitudes all around the planet within southern heavily cratered terrain. The team's report appears in the March 21, 2008 issue of the scientific journal Science.<ref>https://themis.mars.asu.edu/news/salt-deposits-found-martian-highlands</ref>  Since many of the deposits sit in low spots with channels leading into them, they may be similar to salt-pan deposits on Earth.  Water may have flowed there for a long time. To form salt deposits usually much water has to evaporate to leave salt behind.  The places with salts may once held organisms.<ref>https://themis.mars.asu.edu/news/salt-deposits-found-martian-highlands</ref>
