MESSENGER_MAG_RTN (spase://VSPO/NumericalData/MESSENGER/MAG/PT0.05S)
Description
The Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER)
mission is designed to study the characteristics and environment of Mercury from
orbit. Specifically, the scientific objectives of the mission are to
characterize the chemical composition of Mercury's surface, the geologic
history, the nature of the magnetic field, the size and state of the core, the
volatile inventory at the poles, and the nature of Mercurys exosphere and
magnetosphere over a nominal orbital mission of one Earth year
MESSENGER launched on 3 August 2004 at 6:15:56 UT (2:15:56 a.m. EDT) on a Delta
7925H (a Delta II Heavy launch vehicle with nine strap-on solid-rocket
boosters). The spacecraft was injected into solar orbit 57 minutes later.  The
solar panels were then deployed and the spacecraft began sending data on its
status. One year after launch, on 2 August 2005, MESSENGER flew by Earth at an
altitude of 2347 km. On 12 December 2005 at 11:30 UT, MESSENGER fired its large
thruster for 524 seconds, changing the spacecraft velocity by 316 m/s and
putting it on course for its 24 October 2006 Venus flyby at an altitude of 2990
km. The second Venus flyby took place on 5 June 2007 at 23:08 UT (7:08 p.m. EDT)
at an altitude of approximately 337 km. The first of three Mercury flybys, all
at roughly 200 km altitude, occurred on 14 January 2008 at 19:04:39 UT, and the
second on 6 October 2008 at 08:40:22 UT.  The third will be on 29 September
2009. There are also five deep space manuevers. Data collected during the
Mercury flybys will be used to help plan the scientific campaign during the
orbital phase. Mercury orbit insertion will take place on 18 March 2011,
requiring a delta-V of 0.867 km/s. The nominal orbit is planned to have a
periapsis of 200 km at 60 degrees N latitude, an apoapsis of 15,193 km, a period
of 12 hours and an inclination of 80 degrees. The periapsis will slowly rise due
to solar perturbations to over 400 km at the end of 88 days (one Mercury year)
at which point it will be readjusted to a 200 km, 12 hour orbit via a two burn
sequence. Data will be collected from orbit for one Earth year, the nominal end
of the primary mission will be in March 2012.  Global stereo image coverage at
250 m/pixel resolution is expected. The mission should also yield global
composition maps, a 3-D model of Mercury's magnetosphere, topographic profiles
of the northern hemisphere, gravity field to degree and order 16, altitude
profiles of elemental species, and a characterization of the volatiles in
permanently shadowed craters at the poles.
The MESSENGER spacecraft is a squat box (1.27 m x 1.42 m x 1.85 m) with a
semi-cylindrical thermal shade (roughly 2.5 meters tall and 2 meters wide) for
protection from the Sun and two solar panel wings extending radially about 6
meters from tip to tip.  A 3.6 m magnetometer boom also extends from the craft.
The total mass of the spacecraft is 1093 kg, 607.8 kg of this is propellant and
helium. The structure is primarily graphite-cyanate-ester (GrCE) composite and
consists of two vertical panels which support two large fuel tanks and two
vertical panels which support the oxidizer tank and plumbing panel. The four
vertical panels make up the center column and are bolted at their aft ends to an
aluminum adapter. A single top deck panel mounts the LVA (large velocity adjust)
thruster, small thrusters, helium and auxiliary fuel tanks, star trackers and
battery.
Main propulsion is via the 645-N, 317-s bipropellant LVA thruster, four 22-N
monopropellant thrusters provide spacecraft steering during main thruster burns,
and ten 4-N monopropellant thrusters are used for attitude control. There is
also a reaction-wheel attitude control system. Knowledge for attitude control is
provided by star tracking cameras, an inertial measurement unit, and six solar
sensors. Power is provided by the solar panels, which extend beyond the sunshade
and are rotatable to balance panel temperature and power generation, which
provides a nominal 450 W in Mercury orbit. The panels are 70% optical solar
reflectors and 30% GaAs/Ge cells. The power is stored in a
common-pressure-vessel nickel-hydrogen battery, with 11 vessels and 2 cells per
vessel.
Communications are in X-band with downlink through two fixed phased-array
antenna clusters and uplink and downlink through medium- and low-gain antennas
on the forward and aft sides of the spacecraft. Passive thermal control,
primarily a fixed opaque ceramic cloth sunshade, is utilized to maintain
operating temperatures near the Sun. Radiators are built into the structure and
the orbit is optimized to minimize infrared and visible light heating of the
spacecraft from the surface of Mercury. Multilayer insulation, low conductivity
couplings, and heaters are also used to maintain temperatures within operating
limits.
Five science instruments are mounted externally on the bottom deck of the main
body: the Mercury Dual Imaging System (MDIS), Gamma-Ray and Neutron Spectrometer
(GRNS), X-ray Spectrometer (XRS), Mercury Laser Altimeter (MLA), and Atmospheric
and Surface Composition Spectrometer (MASCS). The Energetic Particle and Plasma
Spectrometer (EPPS) is mounted on the side and top deck and the magnetometer
(MAG) is at the end of the 3.6 m boom. Radio Science (RS) experiments will use
the existing communications system.
The Messenger MAG instrument is a miniature three-axis ring-core fluxgate
magnetometer with low-noise electronics. It is mounted on a 3.6 m boom in the
anti-sunward direction. The MAG has .. 1530 and ..51300 nT ranges with 20-bit
internal resolution and 17-bit output resolution. The MAG probe samples magnetic
field values along the X, Y, and Z axes at a rate of up to 20 samples/second
(commandable and can vary). This dataset has 3-axis calibrated samples of the
magnetic field in heliospheric RTN coordinates in units of nano-Tesla, Br, Bt,
Bn. The spacecraft position is identified by radial distance from the Sun,
latitude above the ecliptic plane, and azimuth with respect to the Earth-Sun
line in the ecliptic plane.

MMS1_FGM_BRST_L2 (spase://VSPO/NumericalData/MMS/1/FIELDS/FGM/Burst/Level2/PT0.0078125S)
Description
The Fluxgate Magnetometers (FGM) on Magnetospheric Multiscale consist of a
traditional Analog Fluxgate Magnetometer (AFG), and a Digital Fluxgate
magnetometer (DFG). The dual magnetometers are operated as a single instrument
providing a single intercalibrated data product. Range changes occur at
different times on the two instruments so the gains checked each periapsis can
be carried out unambiguously to apoapsis. Cross correlation of calibration
parameters can separate causes of the any apparent calibration changes. Use of
Electron Drift Instrument (EDI) to determine the field along the rotation axis
allows accurate monitoring of the zero levels along the rotation axis.  Prior to
launch the magnetometers were calibrated at the Technical University,
Braunschweig, except for the AFG magnetometers on MMS3 and MMS4, which were
calibrated at UCLA.  Both sets of sensors are operated for the entire MMS orbit,
with slow survey (8 samples per second) outside of the Region of Interest (ROI),
and fast survey (16 samples per second) inside the ROI. Within the ROI burst
mode data (128 samples per second) are also acquired.  A detailed description of
the MMS fluxgate magnetometers, including science objectives, instrument
description, calibration, magnetic cleanliness program, and data flow can be
found at http://link.springer.com/article/10.1007%2Fs11214-014-0057-3 (DOI 
10.1007/s11214-014-0057-3).Additional information can also be found at
http://www-spc.igpp.ucla.edu/ssc/mms (UCLA),and http://www.iwf.oeaw.ac.at (IWF,
Graz).
For the purpose of creating a unified FGM Level2 data product, burst mode data
is taken from DFG and survey mode data is taken from AFG.  Because AFG and DFG
are cross-calibrated on an orbit-averaged basis, small differences in offset may
be observed between Level2 burst and survey mode data.  Consequently, any
differences are within the error of the measurement. Based on preliminary
analysis of the data, the absolute error within the Region of Interest (ROI) is
estimated to be no more than 0.1 nT in the spin-plane, 0.15 nT along the
spin-axis and 0.2 nT in total magnitude.

version X=5:  * Y-version number comes from cal file entries. 
              *
Ensures there are 2 ephemeris points before/after data to enable proper spline. 

              * Fix to depend_0 of rdeltahalf:  fixes bug when reading position
data.
              * L-vector for DMPA2GSE transformation is smoothed with a
gaussian filter, instead 
                of using a single average value for
the day.  This short-term filter avoids  
                introduding artificial
jumps at 00:00 UTC and removes 7-minute 'wobble' after  
               
maneuvers in the GSE result.   
              * Fixes error with DEFATT file
selection found when choosing the 
                daily DEFATT files to be used
in Phase 2.
              * Fixed bug where reference Etemp was used for high

                     added bit 7 to flag bad data at range changes
             
Added etemp and l1a_mode parameters.

FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest
(ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for
DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s)
resolution.  Per mission design, not all burst-resolution data are downlinked,
but all survey data are downlinked. Planning around calibration activities,
avoidance of Earth radiation belts, etc, when possible, FPI usually operates in
Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product
contains results from integrating the standard moments of phase-space
distributions formed from the indicated data type (DES/DIS burst, FS or SS). For
convenience, some additional parameters are included to augment those most
commonly found in a moments product of this sort, plus time-stamps and other
annotation characterizing the state of the instrument system at the indicated
time.

MMS1_FPI_FAST_L2_DES-PARTMOMS
Description
FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest
(ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for
DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s)
resolution. Per mission design, not all burst-resolution data are downlinked,
but all survey data are downlinked. Planning around calibration activities,
avoidance of Earth radiation belts, etc, when possible, FPI usually operates in
Slow Survey (SS) Mode (60 s resolution) outside of ROI. This product contains
partial moments that come from performing the standard moment integrals over a
limited portion of velocity space. The resulting quantities are named similarly
to their corresponding standard moments, but are decorated with 'part' to
differentiate. For example, density_part is the density moment integrated from a
particular energy step to infinity. These partial moments are formed from the
indicated data type (DES/DIS burst, FS or SS). For convenience, some additional
parameters are included to augment those most commonly found in a moments
product of this sort, plus time-stamps and other annotation characterizing the
state of the instrument system at the indicated time.

MMS1_FPI_FAST_L2_DIS-DIST (spase://VSPO/NumericalData/MMS/1/FastPlasmaInvestigation/DIS/Burst/Level2/Distribution/PT4.5S)
Description
FPI usually operates in Fast Survey Mode in the MMS Region Of Interest (ROI) for
the current Mission Phase.  Data taken at burst (30/150 ms for DES/DIS)
resolution are aggregated on board and made available at survey (4.5 s)
resolution in this mode.  This product contains phase-space distribution maps of
results from surveying the high-resolution observations during each 4.5 s
period.  In particular, the (highest possible quality at the time of release)
corrected/converted "Fast Survey SkyMap" distributions are reported with
time-stamps and other annotation characterizing the state of the instrument
system at the indicated time.

MMS1_SCM_BRST_L2_SCB (spase://VSPO/NumericalData/MMS/1/FIELDS/SCM/Burst/Level2/PT0.0001220703125S)
Description
The tri-axial search-coil magnetometer (SCM) with its associated preamplifier
provides the three-dimensional measurement of the magnetic field fluctuations.
The analog magnetic waveforms measured by the SCM are digitized and processed
inside the digital signal processor (DSP), collected and stored by the central
instrument data processor (CIDP) via the Fields central electronics box (CEB).
Prior to launch, all SCM Flight models were calibrated by LPP at the National
Magnetic Observatory at Chambon-la-Foret (Orleans). Once per orbit, each SCM
transfer function is checked thanks to the onboard calibration signal provided
by DSP. SCM is operated for the entire MMS orbit in survey mode. Within the ROI,
burst mode data are also acquired as well as high burst mode data. 
SCM data set corresponds to the AC magnetic field waveforms in nanoTesla and in
the GSE frame.

MMS2_FGM_BRST_L2 (spase://VSPO/NumericalData/MMS/2/FIELDS/FGM/Burst/Level2/PT0.0078125S)
Description
The Fluxgate Magnetometers (FGM) on Magnetospheric Multiscale consist of a
traditional Analog Fluxgate Magnetometer (AFG), and a Digital Fluxgate
magnetometer (DFG). The dual magnetometers are operated as a single instrument
providing a single intercalibrated data product. Range changes occur at
different times on the two instruments so the gains checked each periapsis can
be carried out unambiguously to apoapsis. Cross correlation of calibration
parameters can separate causes of the any apparent calibration changes. Use of
Electron Drift Instrument (EDI) to determine the field along the rotation axis
allows accurate monitoring of the zero levels along the rotation axis.  Prior to
launch the magnetometers were calibrated at the Technical University,
Braunschweig, except for the AFG magnetometers on MMS3 and MMS4, which were
calibrated at UCLA.  Both sets of sensors are operated for the entire MMS orbit,
with slow survey (8 samples per second) outside of the Region of Interest (ROI),
and fast survey (16 samples per second) inside the ROI. Within the ROI burst
mode data (128 samples per second) are also acquired.  A detailed description of
the MMS fluxgate magnetometers, including science objectives, instrument
description, calibration, magnetic cleanliness program, and data flow can be
found at http://link.springer.com/article/10.1007%2Fs11214-014-0057-3 (DOI 
10.1007/s11214-014-0057-3).Additional information can also be found at
http://www-spc.igpp.ucla.edu/ssc/mms (UCLA),and http://www.iwf.oeaw.ac.at (IWF,
Graz).
For the purpose of creating a unified FGM Level2 data product, burst mode data
is taken from DFG and survey mode data is taken from AFG.  Because AFG and DFG
are cross-calibrated on an orbit-averaged basis, small differences in offset may
be observed between Level2 burst and survey mode data.  Consequently, any
differences are within the error of the measurement. Based on preliminary
analysis of the data, the absolute error within the Region of Interest (ROI) is
estimated to be no more than 0.1 nT in the spin-plane, 0.15 nT along the
spin-axis and 0.2 nT in total magnitude.

version X=5:  * Y-version number comes from cal file entries. 
              *
Ensures there are 2 ephemeris points before/after data to enable proper spline. 

              * Fix to depend_0 of rdeltahalf:  fixes bug when reading position
data.
              * L-vector for DMPA2GSE transformation is smoothed with a
gaussian filter, instead 
                of using a single average value for
the day.  This short-term filter avoids  
                introduding artificial
jumps at 00:00 UTC and removes 7-minute 'wobble' after  
               
maneuvers in the GSE result.   
              * Fixes error with DEFATT file
selection found when choosing the 
                daily DEFATT files to be used
in Phase 2.
              * Fixed bug where reference Etemp was used for high
range gain.  Now uses measured Etemp.

                     added bit 7 to flag bad data at range changes
             
Added etemp and l1a_mode parameters.

Description
FPI usually operates in Fast Survey Mode in the MMS Region Of Interest (ROI) for
the current Mission Phase.  Data are taken at burst (30/150 ms for DES/DIS)
resolution in this mode.  Data are also made available at survey (4.5 s, etc)
resolution; these form a separate product from this.  Per mission design, not
all burst-resolution data are downlinked.  This product contains phase-space
distribution maps of those burst-resolution data selected for downlink.  In
particular, the (highest possible quality at the time of release)
corrected/converted "Burst SkyMap" distributions are reported with time-stamps
and other annotation characterizing the state of the instrument system at the
indicated time.

(ROI) for the current Mission Phase.  Data are taken at burst (30/150 ms for
DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s)
resolution.  Per mission design, not all burst-resolution data are downlinked,
but all survey data are downlinked. Planning around calibration activities,
avoidance of Earth radiation belts, etc, when possible, FPI usually operates in
Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments product
contains results from integrating the standard moments of phase-space
distributions formed from the indicated data type (DES/DIS burst, FS or SS). For
convenience, some additional parameters are included to augment those most
commonly found in a moments product of this sort, plus time-stamps and other
annotation characterizing the state of the instrument system at the indicated
time.

MMS2_FPI_FAST_L2_DIS-PARTMOMS
Description
FPI usually operates in Fast Survey (FS) Mode in the MMS Region Of Interest
(ROI) for the current Mission Phase. Data are taken at burst (30/150 ms for
DES/DIS) resolution in this mode. Data are also made available at survey (4.5 s)
resolution. Per mission design, not all burst-resolution data are downlinked,
but all survey data are downlinked. Planning around calibration activities,
avoidance of Earth radiation belts, etc, when possible, FPI usually operates in
Slow Survey (SS) Mode (60 s resolution) outside of ROI. This product contains
partial moments that come from performing the standard moment integrals over a
limited portion of velocity space. The resulting quantities are named similarly
to their corresponding standard moments, but are decorated with 'part' to
differentiate. For example, density_part is the density moment integrated from a
particular energy step to infinity. These partial moments are formed from the
indicated data type (DES/DIS burst, FS or SS). For convenience, some additional
parameters are included to augment those most commonly found in a moments
product of this sort, plus time-stamps and other annotation characterizing the
state of the instrument system at the indicated time.

MMS2_SCM_BRST_L2_SCB (spase://VSPO/NumericalData/MMS/2/FIELDS/SCM/Burst/Level2/PT0.0001220703125S)
Description
The tri-axial search-coil magnetometer (SCM) with its associated preamplifier
provides the three-dimensional measurement of the magnetic field fluctuations.
The analog magnetic waveforms measured by the SCM are digitized and processed
inside the digital signal processor (DSP), collected and stored by the central
instrument data processor (CIDP) via the Fields central electronics box (CEB).
Prior to launch, all SCM Flight models were calibrated by LPP at the National
Magnetic Observatory at Chambon-la-Foret (Orleans). Once per orbit, each SCM
transfer function is checked thanks to the onboard calibration signal provided
by DSP. SCM is operated for the entire MMS orbit in survey mode. Within the ROI,
burst mode data are also acquired as well as high burst mode data. 
SCM data set corresponds to the AC magnetic field waveforms in nanoTesla and in
the GSE frame.
