Key and Driving Requirements for the Juno Payload Suite of Instruments
Key and Driving Requirements for the Juno Payload Suite of Instruments Randy Dodge1 and Mark A. Boyles2 Jet Propulsion Laboratory-California Institute of Technology, Pasadena, CA, 91109-8099 Chuck E. Rasbach3 Lockheed Martin-Space System Company, Denver, CO, 80201 [Abstract] The Juno Mission was selected in the summer of 2005 via NASA’s New Frontiers competitive AO process (refer to http://www.nasa.gov/home/hqnews/2005/jun/HQ_05138_New_Frontiers_2.html). The Juno project is led by a Principle Investigator based at Southwest Research Institute [SwRI] in San Antonio, Texas, with project management based at the Jet Propulsion Laboratory [JPL] in Pasadena, California, while the Spacecraft design and Flight System integration are under contract to Lockheed Martin Space Systems Company [LM-SSC] in Denver, Colorado. The payload suite consists of a large number of instruments covering a wide spectrum of experimentation. The science team includes a lead Co-Investigator for each one of the following experiments: A Magnetometer experiment (consisting of both a FluxGate Magnetometer (FGM) built at Goddard Space Flight Center [GSFC] and a Scalar Helium Magnetometer (SHM) built at JPL, a MicroWave Radiometer (MWR) also built at JPL, a Gravity Science experiment (GS) implemented via the telecom subsystem, two complementary particle instruments (Jovian Auroral Distribution Experiment, JADE developed by SwRI and Juno Energetic-particle Detector Instrument, JEDI from the Applied Physics Lab [APL]--JEDI and JADE both measure electrons and ions), an Ultraviolet Spectrometer (UVS) also developed at SwRI, and a radio and plasma (Waves) experiment (from the University of Iowa). In addition, a visible camera (JunoCam) is included in the payload to facilitate education and public outreach (designed & fabricated by Malin Space Science Systems [MSSS]). -

Atlas V Juno Mission Overview
Mission Overview Atlas V Juno Cape Canaveral Air Force Station, FL United Launch Alliance (ULA) is proud to be a part of NASA’s Juno mission. Following launch on an Atlas V 551 and a fi ve-year cruise in space, Juno will improve our understanding of the our solar system’s beginnings by revealing the origin and evolution of its largest planet, Jupiter. Juno is the second of fi ve critical missions ULA is scheduled to launch for NASA in 2011. These missions will address important questions of science — ranging from climate and weather on planet earth to life on other planets and the origins of the solar system. This team is focused on attaining Perfect Product Delivery for the Juno mission, which includes a relentless focus on mission success (the perfect product) and also excellence and continuous improvement in meeting all of the needs of our customers (the perfect delivery). My thanks to the entire ULA team and our mission partners, for their dedication in bringing Juno to launch, and to NASA making possible this extraordinary mission. Mission Overview Go Atlas, Go Centaur, Go Juno! U.S. Airforce Jim Sponnick Vice President, Mission Operations 1 Atlas V AEHF-1 JUNO SPACECRAFT | Overview The Juno spacecraft will provide the most detailed observations to date of Jupiter, the solar system’s largest planet. Additionally, as Jupiter was most likely the fi rst planet to form, Juno’s fi ndings will shed light on the history and evolution of the entire solar system. Following a fi ve-year long cruise to Jupiter, which will include a gravity-assisting Earth fl y-by, Juno will enter into a polar orbit around the planet, completing 33 orbits during its science phase before being commanded to enter Jupiter’s atmosphere for mission completion. -
THE ATTITUDE CONTROL and DETERMINATION SYSTEMS of the SAS-A Satellite
THE ATTITUDE CONTROL and DETERMINATION SYSTEMS of the SAS-A SATElliTE F. F. Mobley, A high-speed wheel inside the satellite provides the basic attitude sta B. E. Tossman, bilization for SAS-A. Wobbling of the spin axis is removed by an G. H. Fountain ultra-sensitive nutation damper which uses a copper vane pendulum on a taut-band suspension to dissipate energy by eddy-currents. The spin axis can be oriented anywhere in space as required for the X-ray ex periment by a magnetic control system operated by commands from the ground station at Quito, Ecuador. Magnetic torquing is also used to maintain the satellite spin rate at 1/ 12 revolution per minute. These systems are outgrowths of APL developments for previous satellites, chosen for simplicity and maximum expectation of satisfactory performance in orbit. The in-orbit performance has been essentially flawless. Introduction HE ATTITUDE CONTROL SYSTEM is used to a simple and reliable open-loop system, using orient SAS-A so that the X-ray detectors can commands from the ground. This is very appealing Tscan the regions of the celestial sphere in an or since the weight and power limitations on the derly and efficient manner to detect and measure SAS-A satellite do not permit an elaborate closed new X-ray sources. The two X-ray collimators loop control system. are mounted perpendicular to the satellite spin In addition to detecting and analyzing new (Z) axis. As the satellite rotates slowly about its X-ray sources, the experimenter is interested in Z axis, the detectors scan a 5-degree-wide great correlating X-ray sources with known visible stars, circle path in the celestial sphere. -

The descent probe is a carry-on small spacecraft (< 100 kg), to be deployed by the mother spacecraft, that brings itself onto a collisional trajectory with the targeted planetary body in a simple manner. A possible science payload includes instruments for surface imaging, characterisation of the neutral exosphere, and magnetic field and plasma measurement near the target body down to very low-altitudes (~1 km), during the probe’s fast (~km/s) descent to the surface until impact. The science goals and the concept of operation are discussed with particular reference to Europa, including options for flying through water plumes and after-impact retrieval of very-low altitude science data. -

The Europa Clipper Mission: Investigating an Ocean World's Habitability
PPS01-15 JpGU-AGU Joint Meeting 2020 The Europa Clipper Mission: Investigating an Ocean World's Habitability *Steven Douglas Vance1, Robert T Pappalardo1, David A Senske1, Haje Korth2, Kate Craft2, Sam Howell1, Rachel L Klima2, Erin J Leonard1, Cynthia B Phillips1, Christina Richey1 1. NASA Jet Propulsion Laboratory, California Institute of Technology, 2. The Johns Hopkins University Applied Physics Laboratory Europa is believed to have a liquid ocean beneath its icy shell, abundant physical energy, and drivers for chemical disequilibrium. The Europa Clipper mission will conduct multiple fly-bys of Europa while orbiting Jupiter, with the overarching goal to explore this moon to investigate its habitability. This goal encompasses three Mission Objectives: I. Characterize the ice shell and any subsurface water, including their heterogeneity, ocean properties, and the nature of surface-ice-ocean exchange; II. Understand the habitability of Europa's ocean through composition and chemistry; and III. Understand the formation of surface features, including sites of recent or current activity, and characterize high science interest localities. The Europa Clipper addresses these with a capable payload of scientific instruments, plus gravity/radio and radiation science investigations. NASA selected a payload consisting of both remote-sensing and in-situ-observing instruments. The remote-sensing instruments observe the wavelength range from ultraviolet through radar, which are the Europa Ultraviolet Spectrograph (Europa-UVS), the Europa Imaging System (EIS), the Mapping Imaging Spectrometer for Europa (MISE), the Europa Thermal Imaging System (E-THEMIS), and the Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON). The in-situ-measuring particle instruments comprise the Plasma Instrument for Magnetic Sounding (PIMS), the MAss Spectrometer for Planetary Exploration (MASPEX), and the SUrface Dust Analyzer (SUDA). -
