MetNet Scientific Objectives
* Atmosphere
• Surface to Atmosphere interactions
& the Planetary Boundary Layer
(PBL)
• Atmospheric dynamics and
circulation
• Cycles of CO2, H2O and dust.
• Dust raising mechanisms
* The evolution of Martian climate

MetNet - Future Steps
• Suborbital test launch in 2004/2005 using Russian SS-19.
• PLAN: MetNet Precursor Mars Mission (4 MetNets) -MPMM -onboard the
Phobos Sample Return Mission. (Tillman, Climate Landers)
• PLAN: The MetNet Mission Phase is to deploy an observation network
(tens of landers) around Mars. Mission phase (2009 -2016) consists of
several launches.
• The lander lifetime of several Martian years permits use of 3...5 launch
windows in forming the observational network.
• The network can and will be made thicker and low-performing elements
will be replaced in the course of the Mission.
• Global atmospheric observation network at Mars operational in
2011 --2018 and beyond --> Requires more partners to join the game.

Finnish Meteorology Institute, (FMI) -Live From Earth and Mars - Science, Technology, Education Program (LFEM-STEP)
Collaborative development of the Martian MetNet (MetLander)
Meteorology Network Program
====================
• Martian meteorology observations from the surface play several essential roles.
• Besides their intrinsic interest, they are important for their similarity to those on
Earth, their value in studying complex climate problems applicable to Earth such
as dust and aerosols, and their necessity to develop safe strategies to land on
Mars.

FMI LFEM-STEP Statement
• FMI and LFEM-STEP will collaborate and provide mutual support in the
development of the MetNet Mission.
•
The initial phase will conclude with the launch of the 4 MetNet landers as
the "Prototype Mission" by Russia and their operation for multiple mars
years. continuing as long as the landers function.
• This program is described in the "Climate Landers" component of the Mars
Exploration Strategy as adopted by the IMEWG delegates, Helsinki,
Finland, November 10, 2000.
•
The initial Climate Landers may be directed to the Two Viking Lander sites,
the only source of climate information from the surface of Mars. e.g.,
Viking Lander 1 operated from July 20, 1976 through November, 12, 1982,
2,245 Mars days (sols).
• Tillman initiated the continuation of the last half of its mission and his staff
played an essential role, assuming the Mission Operations downlink
processing role from NASA Jet Propulsion Laboratory.

FMI LFEM-STEP Statement
• Collaboration will include the continued exchange of knowledge and
resources, as has been done during the development of prior missions and
programs by James E. Tillman and collaborators.
• In addition to prior science and technology, this will include a major
Education/Public Outreach component capitalizing on his more than 25
years pioneering such activities.
• Even more than in the past, student collaborators will help develop,
disseminate and support these activities, including Mission Operations.
• LFEM-STEP will acquire significant resources for our developments in
Finland (of the order of 200 kUSD per year) and the United States.

FMI LFEM-STEP Statement
• Its students and collaborators will play a primary role in aspects of the
Prototype Mission, such as naming the spacecraft, and in their operation
as mentioned above.
• As the program progresses, it will be expanded to include more stations,
especially to assure permanent operations at the Viking Sites.
• LFEM-STEP is playing an indispensable role in contributing to the
definition of the METNET science objectives and instrumentation
development.
• Agreed
