Introduction 1.1 General The overall problem we’re solving is that we want to be able to set up the relationships between the coordinates of arbitrary physical points in space (e.g. ground points) and their coordinates on line scanner (or “pushbroom”) camera images. We then want to do a least squares solution in order to come up with consistent camera orientation and position information that represents these relationships accurately. For now, supported by funding from the NASA Critical Data Products initiative (for 2003 September to 2005 August), we will concentrate on handling the THEMIS IR camera system (Christensen et al., 2003). -

Words of Thanks by Dan Sapone
Words of Thanks By Dan Sapone “And yet it moves" (in the original Italian: “Eppur si muove”) — Galileo Galilei, Gentleman of Florence = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = "The Sun, with all its planets revolving around it and depending upon it, still can find the time to ripen a bunch of grapes as if it had nothing else in the universe to do." — Galileo Galilei, 1632 This line first captured my imagination when I saw it on the back label of a bottle of red wine (where else would I look for memorable, meaningful words, eh?). I was looking for some wine for our Thanksgiving dinner table, the family was going to be there, and I would be offering a Thanksgiving Toast — I thought these words were perfect. When the time came, with the bottle in my hand I mentioned that we all have so much to be thankful for: our families, our homes, the work we do, the people who are kind to us, the food and wine we enjoy, and the good times we have. Then, using Galileo’s words, I gave thanks for The Sun, representing all of the ‘greater powers’ that contribute to all of that goodness — whatever and whomever they might be. The words were fun, appropriate to the occasion, and they brought smiles. We lifted our glasses and said “Thanks’ to each other. Galileo’s words helped us do that. A Random Bunch of Thanksgiving Photos “And yet it moves.” Thanksgiving, 2017 Page 1 of 4 Galileo’s Words In Context So, if we let our minds drift back 385 years to Galileo’s time, we learn that he caused quite a kerfuffle, to say the least, when he first used these words. -

Exploration of the Moon
Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when astronauts placed scientific instruments and returnedlunar samples to Earth.

Contents Early history Space race Recent exploration Plans Past and future lunar missions See also References External links Early history The ancient Greek philosopher Anaxagoras (d. 428 BC) reasoned that the Sun and Moon were both giant spherical rocks, and that the latter reflected the light of the former. His non-religious view of the heavens was one cause for his imprisonment and eventual exile.[1] In his little book On the Face in the Moon's Orb, Plutarch suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms. -

Sources: Galileo's Correspondence
Sources: Galileo’s Correspondence Notes on the Translations The following collection of letters is the result of a selection made by the author from the correspondence of Galileo published by Antonio Favaro in his Le opere di Galileo Galilei,theEdizione Nazionale (EN), the second edition of which was published in 1968. These letters have been selected for their relevance to the inves- tigation of Galileo’s practical activities.1 The information they contain, moreover, often refers to subjects that are completely absent in Galileo’s publications. All of the letters selected are quoted in the work. The passages of the letters, which are quoted in the work, are set in italics here. Given the particular relevance of these letters, they have been translated into English for the first time by the author. This will provide the international reader with the opportunity to achieve a deeper comprehension of the work on the basis of the sources. The translation in itself, however, does not aim to produce a text that is easily read by a modern reader. The aim is to present an understandable English text that remains as close as possible to the original. The hope is that the evident disadvantage of having, for example, long and involute sentences using obsolete words is compensated by the fact that this sort of translation reduces to a minimum the integration of the interpretation of the translator into the English text. 1Another series of letters selected from Galileo’s correspondence and relevant to Galileo’s practical activities and, in particular, as a bell caster is published appended to Valleriani (2008). -

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). -

This impacts our knowledge of the formation of these planets and the physics of their atmospheres. A remarkable example of the superiority of in situ probe measurements was illustrated by the exploration of Jupiter, where key measurements such as the determination of the noble gases’ abundances and the precise measurement of the helium mixing ratio were only made available through in situ measurements by the Galileo probe.
