ARES expands upon Viking, Mars Global
Surveyor, Odyssey, Mars Express,
and Mars Exploration Rover discoveries, providing a window
into the structure and evolution of Mars'
atmosphere, surface, and interior.
ARES will return critical science data across up to 610 km
of diverse terrain in one of the most scientifically
intriguing regions of Mars: the Southern Highlands.
ARES has three science goals:
Crustal Magnetism: ARES enables
an improved understanding of the detailed
nature of crustal magnetism on Mars
and modeling of Mars' crustal evolution,
tectonic history and the chronology of its
Atmospheric Boundary Layer
Composition, Chemistry and Dynamics:
ARES enables an improved understanding
of the near-surface atmospheric composition,
chemistry and dynamic behavior, and
the chemical coupling between the surface
and atmosphere, with unprecedented accuracy
Near-Surface Water: ARES enables
an improved understanding of water equivalent
hydrogen abundance and its relationship
to inferred near-surface water
and hydrated minerals.
Primary Science Objectives
ARES will measure the crustal
magnetization, spatial variability, and field magnitude
at km-scale spatial resolution.
ARES will provide the ability to resolve the crustal
magnetism source structure with spatial resolution two orders
of magnitude higher than Mars Global
ARES measurements will allow scientists to determine the role of
water vapor in the Mars atmospheric chemical
ARES will search for potential
biogenic gases, volcanic gases, and chemically
active gases to determine their spatial
distributions and to locate and/or constrain
local sources and sinks.
ARES characterizes the structure
and dynamics of the Mars atmosphere's boundary
layer over regional scales.
ARES will expand upon Mars
Odyssey and Mars Reconnaissance Orbiter measurements by
measuring water-equivalent hydrogen
abundance and ice burial depth at greatly
improved spatial scales.
ARES Bridges Critical Scale and Resolution Measurement Gaps in the Core MEP
From its unique vantage point 1.5 km above the surface of Mars, ARES will target and explore up to 610 km of diverse terrain in the Southern Highlands. Science data will be returned to Earth on the day of flight for immediate scientific review and public dissemination.
ARES' airplane has been developed to autonomously complete a pre-planned science survey. It accommodates Mars environment uncertainty through its robust stability and control performance.
The ARES mission implementation strategy includes flight-proven systems, large margins, and a successful, ongoing airplane deployment assurance program to achieve both mission flexibility and low risk.
