Nuove partenze americane per il pianeta rosso:
January 08, 2007
On Monday, NASA selected for concept study development two proposals for future robotic missions to Mars. These missions would increase understanding of Mars' atmosphere, climate and potential habitability in greater detail than ever before.
In addition, NASA will fund a U.S. scientist to participate in a proposed European Mars mission, as well as fund instrument technology studies that could lead to further contributions to future Mars missions.
"These mission selections represent unprecedented future research that will lead to further advancing our knowledge and understanding of the red planet's climate, and atmospheric composition," said Dr. Mary Cleave, associate administrator for NASA's Science Mission Directorate, NASA Headquarters, Washington.
Each Mars mission proposal will receive initial funding of approximately $2 million to conduct a nine-month implementation feasibility study. Following these detailed mission concept studies, NASA intends to select one of the two proposals by late 2007 for full development as a Mars Scout mission. The mission developed for flight would have a launch opportunity in 2011 and cost no more than $475 million.
The selected Mars mission proposals are:
-- Mars Atmosphere and Volatile Evolution mission, or Maven: The mission would provide first-of-its-kind measurements, address key questions about Mars climate and habitability, and improve understanding of dynamic processes in the upper Martian atmosphere and ionosphere. The principal investigator is Dr. Bruce Jakosky, University of Colorado, Boulder. NASA's Goddard Space Flight Center, Greenbelt, Md., will provide project management.
-- The Great Escape mission: The mission would directly determine the basic processes in Martian atmospheric evolution by measuring the structure and dynamics of the upper atmosphere. In addition, potentially biogenic atmospheric constituents such as methane would be measured. The principal investigator is Dr. Alan Stern, Southwest Research Institute, Boulder, Colorado. Southwest Research Institute, San Antonio, will provide project management.
