Earth Observing System (EOS), AURA

Project Description
Earth Observing System (EOS) Aura is a NASA mission to study the
Earth's ozone, air quality and climate. This mission is designed
exclusively to conduct research on the composition, chemistry and
dynamics of the Earth's upper and lower atmosphere employing multiple
instruments on a single satellite. EOS Aura is the third in a series
of major Earth observing satellites to study the environment and
climate change and is part of NASA's Earth Science Enterprise. The
first and second missions, Terra and Aqua, are designed to study the
land, oceans, and the Earth's radiation budget. Aura's chemistry
measurements will also follow up on measurements which began with
NASA'S Upper Atmospheric Research Satellite and continue the record of
satellite ozone data collected from the TOMS missions.

The EOS Aura satellite, instruments, launch, and science
investigations are managed by NASA's Goddard Space Flight Center in
Greenbelt, Maryland. The satellite was launched in July 2004
and will operated for five or more years. Scientific investigations will
continue throughout the years the spacecraft is in operation and
several years afterwards.

The Aura Project staff includes managers, engineers, administrators
and financial personnel, science advisory personnel, and functional
Working Groups. The Project administers the contracts for each of
Aura's instruments and the Aura spacecraft and specifies the launch
vehicle. They oversee the design, fabrication, assembly and testing of
each instrument and the integration of all the instruments to the
spacecraft. They devise and implement the plans, specifications,
schedules and budgets required to build the Aura spacecraft and deploy
it in orbit. They also provide multi-disciplinary engineering
expertise to deal with diverse technical challenges that occur when
developing, building, and testing a complex spacecraft system.

Aura consists of the following instruments:
High Resolution Dynamics Limb Sounder (HIRDLS)
Microwave Limb Sounder (MLS)
Ozone Monitoring Instrument (OMI)
Tropospheric Emission Spectrometer (TES)

**Aura was successfully launched on July 15, 2004 from
Vandenberg Air Force Base, CA**
