12.400 -  Our Space Odyssey 

spring 2022 class posters_12.400_r1.png

The night sky has guided humanity’s development since the dawn of time. As our societies and technologies evolved, so did our challenges. Could space further nurture our growth via profound experiences such as finding life elsewhere? Join the reflection with a wide range of experts while also learning the fundamentals of astronomy.

Class themes from Spring 2021

Hosted by the Department of Earth, Atmospheric, and Planetary Sciences and taught by Professors Julien de Wit and Richard P. Binzal. 

Upcoming Lectures which are open to MIT alumni will take place 2/25/21 to 5/6/21 from 3-4 pm EST, with exception of April 1st which will be from 7-8 pm EST. Please note the same zoom link will be used for each lecture.

The Concept of Intelligence

Prof. Danilo Bzdok (Biomedical Engineering, McGill University) builds upon the previous session regarding the concept of Life to discuss the concept of Intelligence from a neuroscience and AI perspective.

Intelligence & Meaning (Fundamentals) *5-6:30pm EST

Prof. Edward Hall (Chair of Philosophy Dept, Harvard) concludes our discussion on the concept of Intelligence by examining the processes behind making meaning, building knowledge, and transferring it. Be ready to discuss meaning, knowledge, truth, and worldview.

Our Environment (Challenges) 

Brandon Leschinskiy (Graduate Student, Aero-Astro, MIT) introduces the first main challenge we will consider, our environment --> via “Climate 101”. This presentation was developed by Brandon Leshchinskiy in collaboration with Professor Dava Newman, MIT, and EarthDNA in an effort to mobilize young people as educators on the issue of climate change. The presentation addresses not only the science but also the economics and civics of climate change, incorporating a negotiation activity that brings key concepts to life.

Thursday, March 18th

Our Environment, 2 (Case Study)

Prof. Susan Solomon (EAPS, MIT) introduces two of the key environmental success stories providing a socio-culturo-politico perspective on how to seed change. Such case studies will help students substantiate reflections in their essay.

Susan Solomon:

Our Environment 3 (Case Study)

Profs. Dava Newman (Apollo Program Professor of Astronautics, MIT) and Gui Trotti (Space Architect, Media Lab and AgeLab, MIT) introduce their perspective on environmental challenges together with their AI platform (environment, public engagement, meaning-making, and intelligence). They will also share stories about their personal journeys from leading NASA (Newman) to designing the International Space Station (Trotti).

Racing into the Future, 1 (Challenges)

Prof. Alan Lightman (Humanities, MIT) – astrophysicist, writer and social entrepreneur, introduces us to another challenge with a talk entitled "Racing into the Future: the impact of accelerating advances in science and technology". In this talk, he will reflect on the continuous increase in the pace of our exploration, its connection to the increasing pace of our technological development, and the social, philosophical, theological, and psychological impacts of modern discoveries. 

 Alan Lightman:

Thursday, April 1st

Racing into the Future, 2 (Challenges) *7-8 pm EST

Professor Rev. Ted Peters follows Prof. Lightman’s discussion regarding “Racing into the Future” with a historical and theologian perspective towards “Entering the Third Axial Age.”

Ted Peters:

Tuesday, April 6th

Born in a Cloud (Fundamentals)

Prof. de Wit brings us back to the primordial soup and teaches us how it all turns into a planetary system in “Born in a Cloud”.

Thursday, April 8th

Astronomy and our Prehistory

Profs. Clive Ruggles (Emeritus Professor of Archeoastronomy, University of Leicester, UK) and Michael Rappenglück (Gliching Observatory, Germany)—archeoastronomers authors of UNESCO and IAU’s report on the Heritages of Astronomy—take us back 30,000 years and teach us about the very first artifacts connecting our species to astronomy. Through this case study, we will learn about two processes of meaning-making and knowledge transfer that are connected and yet happening tens if not hundreds of years apart: “What were they thinking?” and “How do we know?”.

Clive Ruggles:

Early Cultures and Geocentrism

Profs. Liba Taub (University of Cambridge, UK) and John Steele (Brown University) bring us further in time to consider later impacts of astronomy focusing on early cultures, from the eastern Mesopotamia to Europe’s medieval ages.

Liba Taub:

John Steele:

The Emerging Field of Astrosociology

Professor Gerhart Sonnert (Harvard) will introduce us to the new and growing field of astrosociology, which studies the social, cultural, and behavioral patterns related to Space with a particular regain of focus on SETI/CETI. Astrosociology is also the title of an engaging and popular course Gerhart teaches at Harvard since 2017.

Gerhart Sonnert: 


Thursday, April 22nd

Planetary Atmospheres (Fundamentals)

Profs. de Wit and Binzel introduce the basic properties and physical observables of planetary atmospheres.

Tuesday, April 27th

Leaving Earth, Looking Back

Astronaut Jeff Hoffman and Frank White will lead this session. Frank is the author and space philosopher who coined the term “Overview Effect” to describe the cognitive shift in awareness that results from the experience of viewing Earth from orbit or the moon. He will discuss the global impact that our race to the Moon has had over the last 60 years. Jeff--MIT Professor, 5-times Space Shuttle Astronaut, rescuer of the Hubble Space Telescope, and Deputy PI of MOXIE--will introduce his personal experience leaving Spaceship Earth.

Integrating Finiteness

Dr. Ariel Elkbaw (Founder and Director of the Space Exploration Initiative, Media Lab, MIT) and Dr. Valentini Sumini (Space Architect, Media Lab, MIT) will discuss the practicalities of developing human space exploration programs. Doing so, we will reflect on Space Exploration as a means to learn more about various types of finiteness (from resources to sensory stimulus) and consider if/how this learning could help us integrate the finiteness of our current spaceship (Earth), which notably underlies current environmental problems. 

Valentina Sumini:
