  1. Finnish Meteorological Institute Ari-Matti HarriMetlander (MetNet) MissionUniversity of WashingtonDept. Atmospheric SciencesJames E TillmanLive From Earth and Mars Science, Technology, Education Partnerships(LFEM STEP)

  2. MetNet - Network • Prototype development in 2001-2003 by FMI & BSC collaborationEntry mass around 15 kgImpact shock < 500 kgEDLS based on inflatable parts - no parachutesTest launch 2004 - 05

  3. 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 Schematic of the major general circulation patterns occurring in the Martian atmosphere (adapted from Fig. 5 of Pollack, 1990a). A: (solstitial) Hadley circulation, B: baroclinic eddies, C: stationary eddies resulting from flow over topography, D: CO2 sublimation flow, E: thermal tides (the Kelvin or normal modes not included)

  4. CHOSEN CONCEPT

  5. 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. MetNet - Future Steps

  6. 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

  7. 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

  8. 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

  9. 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.
