VOYAGER 1 AND 2 MAGNETOMETER SCIENCE DATA PRODUCTION

NASA/Goddard Space Flight Center (GSFC) has a requirement for scientific research for the fully calibrated Voyager 1 and 2 magnetic field data that shall incorporate the spacecraft magroll maneuvers, instrument magcal results, and comparison of the inboard and outboard magnetometer measurements. Spacecraft induced data spikes and offsets shall be removed from the data set. The science research performed with the Voyager 1 and 2 magnetic field data shall demonstrate and validate that the measurements are consistent with the inner and outer heliosheath environment the spacecraft are currently traversing. Expert consultation shall include, but not limited to, expert advice on the proper processing of the Voyager 1 and 2 magnetic field data during long durations of no spacecraft roll maneuvers. The NASA Voyager 1 and 2 spacecraft were launched in 1977 on a mission to explore the outer gas giant planets. After Voyager 2 passed by the Neptune system in 1989, the twin spacecraft were recommissioned to study the outer reaches of our heliosphere and the local interstellar medium, called the Voyager Interstellar Mission (VIM). Voyager 1 crossed the heliopause, the outer boundary of the heliosphere in 2012 entering into the local interstellar medium for the first time. Voyager 2 is expected to reach interstellar space in the next couple of years. Each Voyager spacecraft carries two fluxgate magnetometers on a 13 m boom to measure the ambient magnetic field vectors. Since the magnetometers were optimized for the large fields of the outer planets, calibrating the instruments for the very small outer heliospheric and interstellar fields is a very complex process. The calibration procedure, developed over the past two decades, relies on occasional spacecraft rolls and an internal electronic magcal process. In addition, the measurements obtained by the two magnetometers are compared, and spacecraft induced noises are eliminated. This contract is for the continued execution of this magnetometer calibration process. NASA/GSFC intends to issue a sole-source Request for Proposal (RFP) to BURLAGA, LEONARD F. The data validation process for the magnetometers has been developed and is being executed by Dr. Leonard Burlaga. The estimated period of performance for this firm fixed price (FFP) contract will be for one year plus two option years (total of 3 years).
