SDDPT Mariner 9 Celestial Mechanics Experiment Data Records on CD-WO

NSSDCA ID: PSCM-00002

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Description

The Mariner 9 Celestial Mechanics Experiment Data Records (EDRs) contain the raw radio tracking data for the spacecraft as it orbited Mars. The input data for this CD volume were originally archived on 76 7-track magnetic tapes. These data were transferred to CD-WO as part of NASA's Science Digital Data Preservation Task. The 6 bit characters were padded to 8 bits by placing zeroes into the 2 high order bits.

The file CME_INFO.TXT located on the CD, correlates the tape ID with descriptions of the tapes' contents. Accompanying each tape on the disc, there is a log file which documents SDDPT processing history. The discs are formatted according to the ISO 9660 level 1 Interchange Standard, and file attributes are specified by Extended Attribute Records (XARs).

This data set was created at JPL as part of its Science Digital Data Preservation Task (SDDPT), and a copy was provided to NSSDC for safekeeping. Numerous SDDPT data sets are not readily usable, as they represent bit copies of old data tapes and do not contain user documentation. Persons interested in ordering these data should contact the NSSDC person listed for this data set.

This is SDDPT data set code 75-051A-0013, volume ID M71_1011.
