    Mars Atmosphere & Volatile Evolution Mission (MAVEN)

    The Mars Atmosphere and Volatile Evolution Mission (MAVEN) was launched in November 2013, to explore the planet's upper atmosphere, ionosphere and interactions with the sun and solar wind. After a 10 month ballistic cruise the craft went into orbit in September 2014. The primary mission was planned to last for one earth year. To obtain coverage of near Mars space the mission was designed with an elliptical orbit that precessed in latitude and local solar time. The mission plan included nominal orbits that have periapsis near 150 km, with 5 "deep dip" campaigns with periapsis near 125 km.

    Basic Mission Goals

    Determine the role that loss of volatiles from the Mars atmosphere to space has played through time

    Determine the current state of the upper atmosphere, ionosphere, and interactions with the solar wind

    Determine the current rates of escape of neutral gases and ions to space and the processes controlling them

    Determine the ratios of stable isotopes that will tell Mars' history of loss through time

    Mission Timeline (csv) can be used to select time intervals of interest. This file contains geometry parameters that are associated with the periapse of each orbit and supporting notes that will be updated and enhanced over time.

    Instrumentation and Access to Data:

    The instrument complement consists of:
    1. A mass spectrometer to determine global characteristics of the upper atmosphere and ionosphere,
    2. An ultraviolet spectrometer to characterize the upper atmosphere and ionosphere,
    3. A solar EUV irradiance monitor and
    4. A fields and particles integrated package for in situ measurements. Included in the package are: LPW, SWEA and SEP to measure electrons and SWIA and STATIC to detect ions, while magnetic fields and electric fields are recorded by MAG and LPW respectively.
    5. In addition, accelerometer data is acquired in the 5 "deep-dip" campaigns to sample the lower atmosphere

    Archive Bundles

    MAVEN Mission Bundle contains documents and files that are common to all the instruments describing the mission and spacecraft

    Each of the following archive bundles contain collections for system context, documentation of the data, individual data collections of raw, reduced and/or derived data products complete with calibration information where applicable.

    Neutral Gas and Ion Mass Spectrometer (NGIMS) data are stored in time ordered ASCII tables with supporting documentation

    Accelerometer (ACC) The data from the MAVEN accelerometers will be utilized by a small team to derive atmospheric parameters during periods of near-periapse time ordered ASCII tables with supporting documentation.

    Imaging Ultraviolet Spectrometer (IUVS) data are stored in time ordered FITS files with supporting documentation -higher order products are in FITS.
