Author's Final Note and Acknowledgments AUTHOR’S FINAL NOTE AND ACKNOWLEDGMENTS Despite my complete lack of belief in – and the total absence of any scientific evidence for – astrology, Mars has been a kind of “planet of fate”to me almost all my life. My first memory of the Red Planet takes me way back to the 1960s, the “Golden Age of Apollo,” when my aunt told me that the name “Markus” was derived from the god of war. At the end of the 1970s I prepared a presentation for a physics class at school on Mars. I would have delivered it if I had not caught a bad flu. In the 1980s – as part of my studies in astronomy at the Helsinki University Observatory – I examined the spectral signature of Martian ozone in observations made with the International Ultraviolet Explorer. It was kind of consoling to know that among all the differences between Mars and Earth there are a few similarities, too. At around the same time I covered the Soviet Phobos project with a Finnish input for the Tähdet ja avaruus (“Stars and Space”) magazine of the Ursa Astronomical Association, and made obser- vations of the planet with the instruments of the Ursa Observatory. It was thrilling to see with my own eyes the very same surface features of Mars that the Phobos probes were supposed to be soon studying. In the 1990s I participated in organizing a “Mars Day” in Heureka, the Finnish Science Centre, the program of which con- sisted of short presentations on various aspects of Mars. This gave me – for the first time – a clear insight into the great importance of the Red Planet not only scientifically but also in our culture. And finally, in the beginning of the 2000s, I was looking for – as a managing editor of non-fiction at WSOY, the biggest publishing company in Finland – a book on Mars to be translated and pub- lished in Finnish. I did find several very good books, but I also found that none of them treated the Red Planet comprehensively enough to my taste. Being a stubborn and somewhat arrogant person I decided to start writing one myself. I never would have believed that eventually I would write it in English. John Donne at the beginning of the seventeenth century wrote, “No man is an island” – or, as would be more appropriate in 232 Mars this case, “a planet.”Even though I have typed every single word in this book – as well as in the earlier Finnish edition – with my own fingers, it would not have been born without the strong support and encouragement from a large number of people. First of all I would like to express my deep gratitude to my parents, Kaino and Olavi, who supported my choice of astronomy for a hobby some 30 years ago (goodness me . .) and later for a major subject of my studies. They never questioned my decision but trusted my judgment – perhaps more than I did myself. I thank my wife Helena Sederholm who bravely endured all my miniature lectures on whatever Martian detail happened to be on my mind during the various stages of collecting material for this book and shaping it into an intelligible form. She also read the manuscript and asked some tough questions, the answering of which helped me to – hopefully – clarify what I was trying to say. I am also in great debt to our 4-year-old daughter Tilda Sigrid Meteoora, who made it possible for me to work on “Daddy’s planet” by going to bed without a fuss and sleeping soundly through the night – the time of “day” I did the writing. Of my colleagues in the publishing business I want to say thanks to managing editor Kaarina Miettinen from WSOY, who per- sistently demanded clarifications for things treated with too much complexity or superficiality; non-fiction writer Mattias Tolvanen, whose keen-sightedness helped me avoid a large number of literary pitfalls; and especially graphic designer Martti Ruokonen from WSOY, who created the superb layout for the original Finnish edition and the cover used also in this Springer edition. The illustra- tions made for this book have their origins in the magic pen of graphic designer Mikko Juhola. As a fellow amateur astronomer he managed to find the meaning of my vague instructions and succeeded in bringing to life whole civilizations. The Finnish manuscript was read in its entirety by Professor Juhani Kakkuri and Docent and science journalist Leena Tähtinen. I am grateful for their advice in making the text clearer and scientif- ically accurate. The chapters on Martian research and its results were read by Dr. Ari-Matti Harri from the Finnish Meteorological Institute, the appendix on Finnish participation by Professor Risto Author’s Final Note and Acknowledgments 233 Pellinen – who also kindly wrote the foreword – likewise from the Finnish Meteorological Institute – and the chapter on space probes by science and aviation journalist Jari Mäkinen. Thanks to them I managed to correct several embarrassing mistakes and misun- derstandings. The English manuscript was read by Dr. Diana Hannikainen from the Metsähovi Radio Observatory who also – as a native English speaker – checked the language, making a number of corrections and giving valuable advice on how to say things in English the way they should be said. Major thanks go to editorial director Harry Blom and editor Maury Solomon at Springer ScienceϩBusiness Media. They made the publication of this book possible across the Atlantic, first with Harry’s strong faith in a book written originally only in Finnish and then with Maury’s patient help in transforming it into a thoroughly updated English edition – actually a completely new book. Kiitos! I have also received assistance on details of varying size from the following persons deserving my sincere gratitude: Ralph Aeschliman (www.ralphaeschliman.com), Filipe Alves (www. paragrama.net/manalokos), Matti Anttila (Space Systems Finland Ltd.), Bruce Bradley (Linda Hall Library of Science, Engineering & Tech- nology), Jean-Luc Dauvergne, Louis Friedman (The Planetary Society), Kai Heinonen (Military Museum, Helsinki), Jukka Heiskanen (Sanoma Magazines Finland), Oskari Hellman, Petri Hiltunen, Nick Hoffman, Kimmo Hytti, Kaisa Häkkinen (University of Turku), Markus Jokela (Helsingin Sanomat), Kristian Järnefelt (Hewlett-Packard Finland), Marjo Järvinen, Hannu Karttunen (Tuorla Observatory), Marjatta Koivisto, Johannes Kvist (Oy Suomen Lego Ab), Jukka Lehtinen, Martti Lehtinen (Geological Museum, Finnish Museum of Natural History), Arja Lindblad (WS Bookwell Ltd.), Marcel Maltzeff (WSOY), Matti Martikainen, Alice Martin (WSOY), Terry McNeeley (www. nuclearspace.com), Sini Merikallio (Finnish Meteorological Institute), Franck Montmessin (Service d’Aeronomie du CNRS), Veikko Mäkelä (Ursa Astronomical Association), Heikki Oja (University Almanac Office, Helsinki), Teivas Oksala, Ann Pasquini (Malin Space Science Systems), Leena Peltonen, Timo Polari (www.timopolari.com), Jouko Raitala (University of Oulu), Mario Rossi (www.space-graphics.com), Matti Rossi (Heureka, The Finnish Science Centre), Hannu Salmi 234 Mars (Heureka, The Finnish Science Centre), Matti Salo (Ursa Astronomical Association), Markku Sarimaa (Ursa Astronomical Association), Seppo Sintonen (WSOY), Marjaleena Sorvali (WSOY), Ted Stryk, Pasi Sumanen (WSOY), Paolo Tanga (Unione Astrofili Italiani), Rhys Taylor, Riitta Toiviainen (WSOY), Mikko Tuovinen (Helsingin Sanomat/NYT), Kees Veenenbos (www.space4case.com), Julia Vuori, and Juhani Westman. The writing of this book was supported financially by the Board for Grants and Subsidies to Writers and Translators, the Finnish Association of Non-fiction Writers and the Werner Söderström Corporation Literary Foundation. I am thankful for their trust in my abilities in the field of science writing. The result of my efforts was acknowledged in 2006 with a State Award for Public Information by the Ministry of Education and a citation from the Lauri Jantti Foundation for promotion of Finnish non-fiction. That is something I appreciate very highly. I also want to thank all the anonymous persons participating in the development of the Internet in general and the countless Mars-related websites in particular. Without the benefits of the “triple-w” in searching for information and images the making of this book might not have been impossible, but it would have taken far more time than it did. Equally important are the vast electronic image archives of the various space research organizations, espe- cially those of the National Aeronautics and Space Administration, NASA, and the European Space Agency, ESA. In addition to all the above-mentioned people there certainly is a large group of individuals who have helped me directly or indirectly in the process of putting all this stuff together. I apologize for not being able – or not thinking of it – to name them all.

The model includes up-to-date wavelength-dependent radiative properties of dust, water ice clouds, and gas molecules. It enables the characterization of the radiative environment in different spectral regions under different scenarios. Comparisons between the model results and MetSIS observations will allow for the characterization of the temporal variability of atmospheric optical depth and dust size distribution, enhancing the scientific return of the mission. The radiative environment at the Martian surface has important implications for the habitability of Mars as well as a strong impact on its atmospheric dynamics and climate. Key words.

I would like to thank specially Jordi Ricart for his important dedication to me and this thesis patiently teaching me to make use of the clean room, all the specific equipment needed during the development of the present work and the techniques and procedures involved. It has been a long journey since I first entered the clean room until I felt comfortable carrying out my research which it would have been impossible without his guide. I also owe gratitude to professor Luis Castañer which helped me in the first stages to understand the real challenge which represents Mars exploration to human development and this particular design problem. Hence he allowed me to choose the correct scope according not only to the needs of the project but also to my own interest. Furthermore his experience has been priceless regarding the format and correctness of the present report. Similarly, I give thanks to Lucasz Kowalski for his theoretical explanations with regard to thermal circuits and some fluid dynamics concepts. I want to mention also Gema López and the technical staff of the clean room whose assistance during my work at it, has softened the various problems appeared.

  • Planetary Penetrators: Their Origins, History and Future
    Author's personal copy Available online at www.sciencedirect.com Advances in Space Research 48 (2011) 403–431 www.elsevier.com/locate/asr Planetary penetrators: Their origins, history and future Ralph D. Lorenz ⇑ Johns Hopkins University, Applied Physics Laboratory, Laurel, MD 20723, USA Received 6 January 2011; received in revised form 19 March 2011; accepted 24 March 2011 Available online 30 March 2011 Abstract Penetrators, which emplace scientific instrumentation by high-speed impact into a planetary surface, have been advocated as an alter- native to soft-landers for some four decades. However, such vehicles have yet to fly successfully. This paper reviews in detail, the origins of penetrators in the military arena, and the various planetary penetrator mission concepts that have been proposed, built and flown. From the very limited data available, penetrator developments alone (without delivery to the planet) have required $30M: extensive analytical instrumentation may easily double this. Because the success of emplacement and operation depends inevitably on uncontrol- lable aspects of the target environment, unattractive failure probabilities for individual vehicles must be tolerated that are higher than the typical ‘3-sigma’ (99.5%) values typical for spacecraft. The two pathways to programmatic success, neither of which are likely in an aus- tere financial environment, are a lucky flight as a ‘piggyback’ mission or technology demonstration, or with a substantial and unprec- edented investment to launch a scientific (e.g. seismic) network mission with a large number of vehicles such that a number of terrain- induced failures can be tolerated.

(Tech.) (Finnish Meteorological Institute) Aalto University School of Engineering ABSTRACT OF Degree Programme in Mechanical Engineering MASTER'S THESIS Author: Matti Palin Title: Analysis of aerodynamic stability of the MetNet Entry and Descent vehicle with FINFLO simulations Date: October 31, 2015 Pages: xiv + 86 Major: Aeronautical Engineering Code: K3004 Supervisor: Professor Jukka Tuhkuri Advisors: Professor Timo Siikonen Ari-Matti Harri, D.Sc. (Tech.) (Finnish Meteorological Institute) This Master's Thesis investigates the aerodynamic stability of the MetNet Mars atmospheric entry and descent vehicle, developed in cooperation between the Finnish Meteorological Institute (FMI) and the Lavochin Association (LA). The purpose of the study is performing Computational Fluid Dynamics (CFD) sim- ulations and obtaining the pertinent aerodynamic coefficients for the vehicle in the landing phase to Mars. The results are compared with the values obtained by LA, the most important feature being the aerodynamic stability of the vehicle. In this work, only the static stability is assessed. The simulations were performed with an inhouse FINFLO software. Before the simulations, an atmospheric model of Mars was created. Some initial trajectory calculations were made in order to have approximate values for the combinations of the Reynolds and Mach numbers that the vehicle will experience during the landing. These initial trajectory calculations also provided a condition for the mesh creation.
