Radiation To accomplish its science objectives, Juno orbits over Jupiter’s poles and passes very close to the planet. The elliptical orbit minimizes the exposure to the radiation belts early in the mission.

Juno Spacecraft Description
Juno Spacecraft Description By Bill Kurth 2012-06-01 Juno Spacecraft (ID=JNO) Description The majority of the text in this file was extracted from the Juno Mission Plan Document, S. Stephens, 29 March 2012. [JPL D-35556] Overview For most Juno experiments, data were collected by instruments on the spacecraft then relayed via the orbiter telemetry system to stations of the NASA Deep Space Network (DSN). Radio Science required the DSN for its data acquisition on the ground. The following sections provide an overview, first of the orbiter, then the science instruments, and finally the DSN ground system. Juno launched on 5 August 2011. The spacecraft uses a deltaV-EGA trajectory consisting of a two-part deep space maneuver on 30 August and 14 September 2012 followed by an Earth gravity assist on 9 October 2013 at an altitude of 559 km. Jupiter arrival is on 5 July 2016 using two 53.5-day capture orbits prior to commencing operations for a 1.3-(Earth) year-long prime mission comprising 32 high inclination, high eccentricity orbits of Jupiter. The orbit is polar (90 degree inclination) with a periapsis altitude of 4200-8000 km and a semi-major axis of 23.4 RJ (Jovian radius) giving an orbital period of 13.965 days. The primary science is acquired for approximately 6 hours centered on each periapsis although fields and particles data are acquired at low rates for the remaining apoapsis portion of each orbit. Juno is a spin-stabilized spacecraft equipped for 8 diverse science investigations plus a camera included for education and public outreach.

A Possible Flyby Anomaly for Juno at Jupiter
A possible flyby anomaly for Juno at Jupiter L. Acedo,∗ P. Piqueras and J. A. Moraño Instituto Universitario de Matemática Multidisciplinar, Building 8G, 2o Floor, Camino de Vera, Universitat Politècnica de València, Valencia, Spain December 14, 2017 Abstract In the last decades there have been an increasing interest in im- proving the accuracy of spacecraft navigation and trajectory data. In the course of this plan some anomalies have been found that cannot, in principle, be explained in the context of the most accurate orbital models including all known effects from classical dynamics and general relativity. Of particular interest for its puzzling nature, and the lack of any accepted explanation for the moment, is the flyby anomaly discov- ered in some spacecraft flybys of the Earth over the course of twenty years. This anomaly manifest itself as the impossibility of matching the pre and post-encounter Doppler tracking and ranging data within a single orbit but, on the contrary, a difference of a few mm/s in the asymptotic velocities is required to perform the fitting. Nevertheless, no dedicated missions have been carried out to eluci- arXiv:1711.08893v2 [astro-ph.EP] 13 Dec 2017 date the origin of this phenomenon with the objective either of revising our understanding of gravity or to improve the accuracy of spacecraft Doppler tracking by revealing a conventional origin.

Design and Status of JUNO
Design and Status of JUNO Hans Theodor Josef Steiger on behalf of the JUNO Collaboration Physik-Department, Technische Universität München, James-Franck-Str. 1, 85748 Garching, Germany [email protected] Abstract. The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton multi- purpose liquid scintillator detector currently being built in a dedicated underground laboratory in Jiangmen (PR China). JUNO’ s main physics goal is to determine the neutrino mass ordering using electron anti-neutrinos from two nuclear power plants at a baseline of about 53 km. JUNO aims for an unprecedented energy resolution of 3% at 1 MeV for the central detector, with which the mass ordering can be measured with 3 – 4 σ significance within six years of operation. Most neutrino oscillation parameters in the solar and atmospheric sectors can also be measured with an accuracy of 1% or better. Furthermore, being the largest liquid scintillator detector of its kind, JUNO will monitor the neutrino sky continuously for contributing to neutrino and multi-messenger astronomy. JUNO’s design as well as the status of its construction will be presented, together with a short excursion into its rich R&D program. 1. The JUNO Project – An Overview The Jiangmen Underground Neutrino Observatory (JUNO) is a Liquid Scintillator Antineutrino Detector currently under construction within a dedicated underground laboratory (~700 m deep) close to Jiangmen city (Guangdong province, PR China). After the completion, it will be the largest liquid scintillator detector ever built, consisting 20 kt target mass made of Linear Alkyl-Benzene (LAB) liquid scintillator (LS), monitored by about 18000 twenty-inch high-quantum efficiency (QE) photo- multiplier tubes (PMTs) and about 26000 three-inch PMTs providing a total photo coverage of ∼78%.

Galileo Telecommunications
Chapter 4 Galileo Telecommunications Jim Taylor, Kar-Ming Cheung, and Dongae Seo 4.1 Mission and Spacecraft Description This chapter describes how the Galileo orbiter received and transmitted data with the Deep Space Network (DSN). The relay communications subsystems and the link between the Galileo probe and the orbiter are also described briefly. The chapter is at a functional level, intended to illuminate the unique mission requirements and constraints that led to both design of the communications system and how the mission had to be modified and operated in flight. Augmenting the spacecraft downlink design and the supporting ground system for science return with only the low-gain antenna (LGA) was a particular challenge for the Galileo planetary mission. The Galileo orbiter was designed and built at the Jet Propulsion Laboratory (JPL) in Pasadena, California, and the Galileo probe was designed and built at the NASA Ames Research Center (ARC) in Sunnyvale, California. The orbiter flight team was located at JPL, as was the probe flight team during that portion of the mission. 4.1.1 The Mission The Galileo spacecraft was launched in 1989 aboard the Space Shuttle Atlantis (STS [Space Transportation System]-34). Its primary objective was to study the Jovian System. The Galileo launch delay after the Challenger Space Shuttle 81 82 Chapter 4 accident in 1986 necessitated a change in the strategy to get Galileo to Jupiter.1 The original strategy was a relatively direct flight to Jupiter with a single gravity assist at Mars. The new mission plan had to work with less propulsion, so it made use of a longer, much less direct flight, with gravitational assists from Venus once and Earth twice, to give the spacecraft enough energy to get to Jupiter.

Activity 2. Starry Messenger: Close Reading. Teacher's Version
Activity 2. Starry Messenger: Close Reading. Teacher’s Version Preliminary Notes • This close reading is divided into seven sections of varying length in the left-hand column. Directed questions and explanatory text are found in the right-hand column along with focus questions that respond to CCSS.ELA-Literacy.RST.6-8.4, 7, and 9. • The Launchpad does not contain the question answers or the supplementary comments. It is suggested that the student version of the questions, which appears in the Launchpad version of the handout, be distributed after the close reading of the section(s) at the discretion of the teacher. • Academic vocabulary is bolded only in the teacher’s version; see the Teacher’s and Student version worksheets of the complete lists of vocabulary items. • Call-outs for the handouts of Galileo’s drawings of Orion and the Pleiades are introduced in Section 5 of both the Teacher’s and student version, and in the Launchpad. ****************************************************************************** Suggested Sequence for Close Reading Reading 1 The teacher will model a reading of the entire first section with the class. Instruct them as they read to highlight unfamiliar words or passages. For each chunk of text, have students briefly note what they think it means. Reading 2 Read again the first section aloud to the class, modeling the types of questions that students will be answering when they read the rest of the sections on their own. Individual Readings If feasible, divide the class into small groups of 3 students each and have each group read aloud the six remaining passages to the class, finding answers to the focus questions (right hand column and on their graphic organizer).
