Without the implementation of the magnetic cleanliness program\, key scientific i nstruments such as the magnetometer science instrument as well the Microwa ve Radiometer (MWR) instrument would not be able to perform in the presenc e of high magnetic fields from the spacecraft and Jupiter. The magnetic cl eanliness program was applied from early flight system development up thro ugh system level environmental testing. The JUNO magnetic cleanliness prog ram required setting-up a specialized magnetic test facility for testing t he flight system and a testing program with a facility for testing subsyst em parts and subsystems at JPL. The magnetic modeling\, simulation and ana lysis capability was set up and performed in order to provide qualitative and quantitative magnetic assessments of the magnetic parts\, components\, and subsystems prior to or in lieu of magnetic tests. Because of the sens itive nature of the fields and particles scientific measurements as well a s the microwave radar instrument being conducted by the JUNO space mission to Jupiter\, the imposition of stringent magnetic control specifications required a magnetic control program to ensure that the spacecraft’s scie nce magnetometers and plasma wave search coil were not magnetically contam inated by flight system magnetic interferences. With component and subsyst em magnetic modeling\, simulation and analysis as well as system modeling and comprehensive testing\, the project accomplished a cost-effective appr oach to achieving a magnetically clean spacecraft. The lecture will focus on the approach that was implemented and describe the scientific results t hat benefited from the efforts to control spacecraft interference and magn etic contamination of science instruments. This lecture presents lessons l earned from the JUNO magnetic testing approach and modeling\, simulation a nd analysis activities used to solve problems such as remnant magnetizatio n\, performance of hard and soft magnetic materials within the targeted sp ace system in applied external magnetic fields and how these lessons learn ed are being applied to future Jupiter bound spacecraft such as the Europa Clipper and Lander.\n\nThe NASA Europa Clipper spacecraft with its nine s cience instruments will orbit Jupiter’s icy moon Europa to investigate w hether the icy moon could harbor conditions suitable for life. Of those ni ne science instruments\, there are two magnetically sensitive ones: The Pl asma Instrument for Magnetic Sounding (PIMS) and the Interior Characteriza tion of Europa using Magnetometry (ICEMAG). The two instruments will measu re the strength and direction of the moon’s magnetic field to determine the depth and salinity of its ocean\, which hence leads to unique DC magne tic requirements. The lecture will also focus on the DC magnetic model ana lysis that was performed on Europa Clipper spacecraft to guide design trad es and provide an early assessment for the spacecraft in order to ensure t hat the unique DC magnetic requirements can be met and validated by test i n the future.\n\nCo-sponsored by: Kathleen Kramer\n\nSpeaker(s): Pablo Sim on Narvaez\, \n\nBldg: Advanced Test Equipment Rentals\, 10401 Roselle St\ , San Diego\, California\, United States LOCATION:Bldg: Advanced Test Equipment Rentals\, 10401 Roselle St\, San Die go\, California\, United States ORGANIZER:vsalehi@ieee.org SEQUENCE:19 SUMMARY:Results of the JUNO Jupiter Mission and the Difficulty in Designing the Spacecraft to Operate in Harsh Environment Existing in Jupiter\, and Lessons Learned Applied to the Upcoming Europa Clipper Mission URL;VALUE=URI:https://events.vtools.ieee.org/m/206466 X-ALT-DESC:Description: <br /><p>&nbsp\;<strong>Topics: </strong>Jet Propul sion Laboratory (JPL) implemented a comprehensive magnetic cleanliness pro gram of the NASA/JPL JUNO mission which is currently orbiting Jupiter and returning invaluable scientific data.
