END_OBJECT = TEXT END Mars Obiter Mission (MOM) - Mars Colour Camera (MCC) Data Archive ================================================================== 1. Introduction ================================================================== The main objectives of the Mars Orbiter Mission (MOM) are technological in nature pertaining to the development of technologies required for design, planning, management and operations of an interplanetary mission, besides the scientific objectives listed below: - Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments. The Mars Orbiter Mission (MOM) comprises three distinct phases: -Earth-centric (Geocentric) Phase: MOM orbits around Earth - Sun-centric (Heliocentric) Phase: MOM orbits around the Sun - Mars-centric (Aerocentric) Phase: MOM orbits around Mars The transition from Earth-centric Phase to Sun-centric Phase happened by Trans Mars Injection (TMI) and from Sun-centric Phase to Mars-centric Phase by Mars Orbit Insertion (MOI) paving way for Indian exploration of planet Mars. The average accuracy of orbit information provided can vary in 1-50 km range. Read MISSION.CAT for further details for understanding image acquisition details with varying spacecraft altitudes. Mars Orbiter Mission carries five payloads viz., Mars Color Camera (MCC), Methane sensor for Mars (MSM), Thermal Infrared Imaging Spectrometer (TIS), Mars Exospheric Neutral Composition Analyzer (MENCA) and Lyman Alpha Photometer (LAP). Two out of the five payloads, MCC and MSM are imaging payloads and the other 3 are science payloads. The key parameters considered for imaging is the sun illumination and imaging altitude or position in the orbit, since the orbit proposed is a highly elliptical one with the altitude variation of 72,000 km at the apoareion to 370 km at the peri-areion. MCC, MSM and TIS: MCC, MSM and TIS are mounted with the bore-sight along the spacecraft body yaw axis. They are operated with the spacecraft yaw pointing towards the center of MARS. MCC is a 4 megapixel digital camera that employs a RGB Bayer pattern detector to record images in the visible region (0.4 micrometer to 0.7 micrometer) of the spectrum. MCC is meant for returning visual images of Mars and its environs, monitor dynamic Martian phenomenon like dust storms and dust devils and to provide context information to all other payloads on the Mars orbiter. The expected spatial resolution is better than 20m from its closest approach (known as Periareion) of nearly 370km to Mars whereas from the farthest point (known as Apoareion)of 80,000km from Mars, MCC images will have a resolution of 4km. These data sets belong to Mars Phases. The MCC products archived on this volume are the exact products released by the MOM Project. Supporting documentation and label files conform to the Planetary Data Systems (PDS) Standards Reference, August 2003, Version 3.6, JPL D-7669,Part 2. ================================================== 2. VOLUME FORMATS ================================================== This is an electronic edition of data set and hence compatible with a large variety of computer systems. ================================================== 3. File FORMATS ================================================== 3.1 FILE EXTENSIONS Files on this volume are named according to PDS standards, where the 1-3 characters after the period indicate the file type. The file types used on this volume are: Binary files: Binary data files *.IMG,*.QUB SPICE ephemeris files *.BSP Adobe Acrobat documentation files *.PDF Postscript documentation files *.PS Microsoft Word Document *.DOC ASCII text files: *.TXT PDS labels *.LBL ASCII tables and indices *.TAB Spreadsheet *.CSV PDS catalog files *.CAT Text documentation files *.TXT Source code files *.C, *.H, *.FOR, *.INC, *.CPP, *.JAVA Software build scripts *.COM, *.MAK, *.DEF SPICE kernels *.TLS, *.TPC, *.TSC, *.BC SPICE transfer ephemeris files *.XSP Other files (for documentation only) *.LOG, *.OUT 3.2 PDS LABELS Every file in this data set is described by an associated PDS label. Most files are described by a detached label, which has the same name as the corresponding file but an extension ".LBL". Most text files (*.TXT, *.CAT) have attached labels. In some cases, all or most of the files in a given directory share a single, abbreviated "combined-detached" label. In this case, the name of the file is the name of the enclosing directory, with extension ".LBL". See the PDS Standards Reference (JPL D-7669) for a complete description of the PDS label format. This document can also be found online at http://pds.jpl.nasa.gov/stdref/ 3.3 ASCII TEXT FILES Different popular operating systems use different standards for how ASCII text files are formatted. On Unix systems, lines are terminated by a >LF< (linefeed character, control-J, ASCII 10). On Macintosh computers, lines are terminated by a >CR< (carriage return character, control-M, ASCII 13). On PCs, lines are terminated by a >CR<>LF< pair. PDS standards require all text files to use >CR<>LF< line termination. If the PDS label indicates INTERCHANGE_FORMAT = ASCII or RECORD_TYPE = STREAM, then this line termination is in use. On occasion, users on Unix and Macintosh computers may need to change the line termination on some text files before they can use them. This can be handled via text editors or a variety of utilities. For example, the Unix tr (translate) command can be used to change carriage returns to blanks: tr "\015" " " >oldfile.txt CR<>LF< line terminators, and these two bytes are included in the byte count. For this reason, it is unwise to convert the line terminator to a single character (>LF< on Unix or >CR< on Macintosh) because this can change the number of bytes per record and invalidate the label. In these situations, it is recommended that the line terminator be replaced by a space plus >LF< or a space plus >CR< instead. 3.4 BINARY FORMATS Binary data file formats differ among hardware platforms. Most binary files are provided in these formats: IEEE: For Sun, SGI and Macintosh platforms. Integers appear with most significant byte first; floating-point numbers appear in IEEE format. PC: For PC platforms. Integers appear with least significant byte first; floating-point numbers appear in byte-reversed IEEE format. ======================================================================== 4.
