Vision Statement The Space Science Institute is a thriving center of talented, entrepreneurial scientists, educators, and other professionals who make outstanding contributions to humankind’s understanding and appreciation of planet Earth, the Solar System, the galaxy, and beyond. 2 | Space Science Institute | Annual Report 2005 From Our Director Excite. Explore. Discover. These words aptly describe what we do in the research realm as well as in education. In fact, they defi ne the essence of our mission. Our mission is facilitated by a unique blend of on- and off-site researchers coupled with an extensive portfolio of education and public outreach (EPO) projects. This past year has seen SSI grow from $4.1M to over $4.3M in grants, an increase of nearly 6%. We now have over fi fty full and part-time staff. SSI’s support comes mostly from NASA and the National Sci- ence Foundation. Our Board of Directors now numbers eight. Their guidance and vision—along with that of senior management—have created an environment that continues to draw world-class scientists to the Institute and allows us to develop educa- tion and outreach programs that benefi t millions of people worldwide. SSI has a robust scientifi c research program that includes robotic missions such as the Mars Exploration Rovers, fl ight missions such as Cassini and the Spitzer Space Telescope, Hubble Space Telescope (HST), and ground-based programs. Dr. Tom McCord joined the Institute in 2005 as a Senior Research Scientist. He directs the Bear Fight Center, a 3,000 square-foot research and meeting facility in Washington state. -
3.1 Discipline Science Results
CASSINI FINAL MISSION REPORT 2019 1 SATURN Before Cassini, scientists viewed Saturn’s unique features only from Earth and from a few spacecraft flybys. During more than a decade orbiting the gas giant, Cassini studied the composition and temperature of Saturn’s upper atmosphere as the seasons changed there. Cassini also provided up-close observations of Saturn’s exotic storms and jet streams, and heard Saturn’s lightning, which cannot be detected from Earth. The Grand Finale orbits provided valuable data for understanding Saturn’s interior structure and magnetic dynamo, in addition to providing insight into material falling into the atmosphere from parts of the rings. Cassini’s Saturn science objectives were overseen by the Saturn Working Group (SWG). This group consisted of the scientists on the mission interested in studying the planet itself and phenomena which influenced it. The Saturn Atmospheric Modeling Working Group (SAMWG) was formed to specifically characterize Saturn’s uppermost atmosphere (thermosphere) and its variation with time, define the shape of Saturn’s 100 mbar and 1 bar pressure levels, and determine when the Saturn safely eclipsed Cassini from the Sun. Its membership consisted of experts in studying Saturn’s upper atmosphere and members of the engineering team. 2 VOLUME 1: MISSION OVERVIEW & SCIENCE OBJECTIVES AND RESULTS CONTENTS SATURN ........................................................................................................................................................................... 1 Executive -
Saturn Customers Can Now Try out Shopping with Augmented Reality
New technology to tour Germany Saturn customers can now try out shopping with augmented reality . Virtual objects are integrated into the real environment . Avatar Paula guides customers through this new shopping experience . Demonstrations in Germany's largest Saturn stores Ingolstadt, 02.05.2017: How about chasing Pokémon Go monsters right across town, testing which TV looks best in your living room, or even trying on new clothes without having to go into the changing room? Something which only recently still seemed like science fiction has now been made possible – by augmented reality. In early May, Saturn will be taking its grand ‘HoloTour’ on the road to present this brand new technology in selected stores. Customers will be able to explore a new shopping experience in which virtual items are displayed in real environments, hence ‘augmenting’ the perception of reality. It all works on the basis of special smartglasses, the Microsoft ‘HoloLens’, which project 3-D images and information into the normal field of vision. Running until the end of July, the HoloTour will stop off at 20 Saturn stores in German cities. “During the HoloTour, once again we’re enabling Saturn’s customers to experience innovative technology,” declared Martin Wild, Chief Digital Officer of the MediaMarktSaturn Retail Group. “We’ll be showing our customers the fascinating possibilities offered by augmented reality and providing a glimpse of tomorrow’s far more personalized shopping. Moreover, we’ll be finding out how our customers interact with the new technology.” Mixed reality Like virtual reality, augmented reality also requires a special headset. For Saturn’s 1 / 4 demo tour, the HoloLens developed by Microsoft will be used – smartglasses which move holograms and multimedia content into the field of vision without blocking genuine reality. -

Saturnis the Second of the 4 Gas Giants. Like Jupiter It Gives Off More
Saturn is the second of the 4 gas giants. Like Jupiter it gives off more heat than it gets from the Sun. But unlike Jupiter, it has a magnificent set of rings, and it's so light that it would float in water - if you could find a bath big enough! Saturn is about 120,000 km across. It takes 29.46 years to go around the Sun. Like Jupiter, it spins very rapidly - the day lasts for 10 hours and 39 minutes. It has a similar structure to Jupiter. It has a solid core, which is surrounded by a shell of solid hydrogen, which is in turn surrounded by a shell of liquid hydrogen, and then the giant shell of atmosphere. This atmosphere is made of hydrogen and helium gases, and ammonia, with small amounts of other gases. Like Jupiter, Saturn seems to be a bubbling cauldron of liquid and gas. Like Jupiter, the atmosphere of Saturn is NOT in chemical balance, with some unknown process making trace amounts of various gases. Like Jupiter, Saturn gives out more heat than it gets from the Sun. But the heat is made in a different way. On Saturn, the heat comes from the condensing of helium as it sinks in the atmosphere. In the same way that steam gives off heat as it turns from gas into liquid, so helium gives off heat. This heat is is the power supply for the weather of Saturn. Saturn has fierce winds which travel at some 1,700 km/hr near the equator - 3.5 times faster than the winds on Jupiter. -

Saturn Tests Cashierless Payments in Germany, Too
Pilot project at Saturn in Munich Saturn tests cashierless payments in Germany, too § After Saturn Express in Innsbruck, SATURN Smartpay pilot project with self-checkout launched in Munich § Simple in-app payment § Innovative security tag can be deactivated by customers IngolstaDt, 14.09.2018: Queuing up at the checkout is now a thing of the past! Following the huge success of Saturn’s pilot project with Europe’s first self- checkout consumer electronics store in Austria, the company is now also testing mobile payments in Germany. Customers can now pay for selected products from the heaDphone Department at Saturn’s store in Munich’s biggest shopping centre PEP using the app SATURN Smartpay. The great thing is that customers can also deactivate the anti-shoplifting system themselves anD then immeDiately leave the store with their purchase. ScheDuleD to run until the enD of November, this pilot project is being conDucteD in conjunction with Munich-baseD startup Rapitag. SATURN Smartpay combines the advantages of offline anD online shopping: customers benefit from the real-world shopping experience anD consumer advice from shop assistants, yet self-checkout simply takes place on an app. “No one really enjoys queuing, but there’s not yet a standard solution for cashless payment. That’s why we’re trying out different innovative systems,” explained Martin Wild, Chief Innovation Officer of the MediaMarktSaturn Retail Group. “We’re delighted to be able to acquire new, valuable experience in this field with the German-made Rapitag solution.” Using SATURN Smartpay, the consumer electronics retailer wants to find out how mobile payments go down with its customers in Germany. -

SPECIAL SITUATION REPORT 09 June 2016 Metro (MEO GY) Demerger terms Demerger 1 MEO GY = 1 C&C + 1 MSH Announced demerger: At end of March 2016 Metro announced its demerger into Metro Group two separate listed entities planned by mid-2017. The two separated companies would be a food retailer (C&C) and a consumer Country Germany electronics retailer (MSH) company. Metro IR confirmed to us that each Metro shareholder would receive one Bloomberg MEO GY share in each of the separated companies. Sector Food & Drug Stores The key rationale behind the demerger is the following: Share price (€) 29.53 Removal of the conglomerate discount; Potentially higher valuation multiples of the two separate entities; Market cap (€m) 9,004 The two independent entities potentially becoming takeover targets. Free float % ~47 Key risks before demerger Approvals: Transaction requires management board, supervisory board, and AGM approvals. The key approval appears to be the AGM approval where 75% of the vote cast is needed – confirmed by MEO IR. Timing: Completion is aimed for mid-2017. IR confirmed to us that completion means the newly listed company will be available for trading. IR told us they would not comment on timeline in more detail. Index composition: Metro is currently a member of MDAX. Based on our highly Metro Price Chart conservative assumptions, both companies are likely to remain part of MDAX; however the new entity has to go through the entry process. Our assumption has been confirmed by MEO IR. We assumed: i) no upside to the demerged parties, ii) net debt will be broken up based on EV ratios of 3:1 (C&C:MSH), iii) current share prices of other MDAX components.
