Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Phoenix

NASA's Phoenix lander, which launched August 4, 2007 and landed on Mars on May 25, 2008 23:53 UTC, was sent to the surface of Mars to search for evidence of past or present microbial life. The robotic arm could dig through the protective top soil layer to the water ice below and ultimately, bringing both soil and water ice to the lander platform for sophisticated scientific analysis.. Besides verifying the existence of water-ice in the Martian subsurface, Phoenix discovered traces of the chemical perchlorate, a possible energy source for microbes and a potentially valuable future resource for human explorers.

The complement of the Phoenix spacecraft and its scientific instruments were ideally suited to uncover clues to the geologic history and biological potential of the Martian arctic. Phoenix was the first mission to return data from either polar region providing an important contribution to the overall Mars science strategy "Follow the Water" and was instrumental in achieving the four science goals of NASA's long-term Mars Exploration Program.

Determine whether Life ever arose on Mars

Characterize the Climate of Mars

Characterize the Geology of Mars

Prepare for Human Exploration The Phoenix Mission has two bold objectives to
support these goals, which are to (1) study the history of water in the Martian arctic
and (2) search for evidence of a habitable zone and assess the biological potential of
theice-soil boundary.

As planned, the robot onboard the Phoenix lander worked on Mars for three months of prime mission, plus two months of overtime, ending communications in November 2008, about six months after landing, when its solar panels ceased operating in the dark Martian winter. Besides verifying the existence of water-ice in the Martian subsurface, Phoenix discovered traces of the chemical perchlorate, a possible energy source for microbes and a potentially valuable future resource for human explorers. The Phoenix science team will be analyzing data and running comparison experiments for months to come.
