Six landing sites that show evidence for processes involving water have been selected from a possible 185 for the Mars Exploration Rovers. These sites are being imaged by orbiting spacecraft and evaluated for science potential and safety before selection of two in May 2002. Additional information is contained in the original extended abstract.
Preliminary engineering constraints on Mars Exploration Rover landing sites are derived, mapped into remote sensing criteria, and used to identify potential landing sites. High-priority sites via an open request to the science community and future plans are described. Additional information is contained in the original extended abstract.
The baseline scenario for the Mars 2003/2005 Sample Return Mission utilizes Mars orbit rendezvous to retrieve two orbiting sample canisters containing Martian surface material.
The primary objective of the Mars 2003/2005 Sample Return Project is to return Martian surface materials to Earth from two different sites by the year 2008.
The value of EOT in degrees is usually converted to solar-minutes to give the correction to mean solar time to obtain true solar time. The value of EOT for Mars over the Mars Observer mapping phase is plotted.
This memo is an update to the Mars Observer Planetary Constants and Models document, published November 1990.
In May 2003, a new and exciting chapter in Mars exploration will begin with a launch that will ultimately lead to the delivery of samples from the Red Planet to Earth.
