A Simple Response to an Elemental Message (ASREM) was an Interstellar Radio Message (IRM) consisting primarily of 3775 worldwide responses to this initiative's posed question; "How will our present, environmental interactions shape the future?" This transmission also features a smaller 'Honorary Mention' text archive and a series of images of Earth.

This interstellar "message in a bottle" was transmitted on 10 October 2016, at 20:00 UTC by the European Space Agency Cebreros (DSA2) deep-space tracking station towards Polaris; the Pole Star which is approximately 434 light years (133 parsecs) from Earth. [1] The IRM consisted of a single 27,653,733 byte, 866 second transmission.

Concept and plan overview

The not-for-profit ASREM initiative was devised and produced by artist Paul Quast in collaboration with the UK Astronomy Technology Centre, European Space Agency and the University of Edinburgh along with researchers working at the Johns Hopkins University and also the European Southern Observatory.

Unlike other IRM, the transmission's stated purpose was devised for a terrestrial, 'overview effect' application; "to look at our civilisation's past, present and future environmental interactions on Earth by using light's 'round trip' from our planet's Pole Star as a symbolic and temporal odyssey". [2] This initiative's narrative examined the 'Critical Decade' [3] (2010-2020); a pivotal point within our civilisation's history proposed by a series of climate researchers in which present ecological decisions may irreversibly commit future generations to adversity. The worldwide public were challenged to consider their role within shaping the planet's future biosphere in the newly defined Anthropocene era while also considering approaches which may be adopted to resolve climatic/biological concerns faced on Earth today.

The research purpose of this initiative and its publicly generated material (besides its resonant legacy travelling through space) was outlined by its authors as: "the submitted content was also accumulated to contribute to ongoing dialogue on how our civilisation collectively foresees its role within shaping Earth's future biosphere and provide a means to analyse these perspectives for cross-cultural universals between nations within further academic research." [2] An initial analysis of this submitted material [4] has already provided a number of insights into the noösphere of participating countries with further examinations currently ongoing.

As well as providing engagement with the worldwide public on these pertinent concerns, a number of climate scientists and astronomers also contributed to this initiative; submitting perspectives gained from their various fields of research conducted within Antarctica, the Arctic and other research facilities located around the world.

Target

The organisers of this transmission stated that Polaris α UMi Aa was chosen "due to the cultural iconography this star possesses, its tangible links to the transmissions stated ecological narrative and the possibility to provide a contemporary, environmental chapter to the Pole Star's symbology". In Greek, the star was known as the Cynosure (original; Kynosoura), a title which later entered the English language to denote "an object that serves as a focal point of attention and admiration" or "something that serves to guide".

The Polaris planetary system, even if it exists, may not be suited for life, because it is a supergiant type F7Ib star in a triple star system [with nearby companions] which should (to present knowledge) possess very powerful stellar winds around its vicinity. [5] In addition to this, the age of Polaris has been calculated to be approximately 70 million years [6] and thus this star may be too young to support the development of life. Another IRM entitled Across the Universe was previously sent towards this stellar location by NASA's nearby MDSCC facility in 2008.

Message components

This transmission consisted of four components in the order; AM → IMAGES → AM → IMAGES → AM → MES → HM

While the transmission may be intercepted by an ETI en route to Polaris, besides the image archive, the contents may not be decipherable. In addition to this, the transmission rate was very high, ~256 kbit/s at a transmitting power of 19.953 kW. This transmission was also the last initiative to utilise the frequency of 7168.0089310 MHz, the bandwidth formerly dedicated to ESA's Rosetta Mission.

Potential dangers and detectability

While this transmission was primarily developed to advance an 'overview effect' perspective, the initiative also served to reignite debate on the benefits, dangers and ethics of transmitting into interstellar space. Days prior to the transmission on 10 October, the British theoretical physicist Stephen Hawking reiterated his concerns for contacting ETI, specifically regarding aliens' deportment. [8] Days later, SETI scientists Seth Shostak and Douglas Vakoch presented their own individual perspectives on this subject and the greater challenges facing any potential continuation of Active SETI/METI activities. [9] [10]

In a 2016 article, Douglas Vakoch, President of METI International, addressed the ASREM initiative and its relationship to themes highlighted within SETI's 'Earth Speaks', stating;

"One of the strongest themes we see in 'Earth Speaks' is a concern with our current environmental crisis. In answering the question 'How will our present environmental interactions shape the future?' we need to reflect on what it will take to sustain Earth's civilization in the coming centuries. That can only be a good thing.". [11]

In addition to this, scientists from the Teen Age Message (2001), Cosmic Call (1999 & 2003) and Lone Signal (2013) IRM initiatives were also consulted and aided in advising on this transmission. Aleksandr Zaitsev, an expert in interstellar radio communication and Chief Scientist of the Radio Engineering and Electronics Institute of the Russian Academy of Science, pointed out the futility of choosing Polaris as a target considering it is a supergiant star with relatively poor potential to host alien life.

Numerous climate scientists and SETI researchers were consulted during production of this interstellar initiative, all of which possessed shared or differing opinions on the use of an IRM time capsule to support an ecological endeavour. However, all researchers generally agreed upon the volatile nature of Earth's contemporary environment and the need to raise awareness and action to avert ecological crises.

ASREM (English version) initially launched on 30 November 2015 to coincide with the United Nations COP21 Climate Conference in Paris. It gained a large number of submissions over the duration of this summit before launching additional language options in February 2016 (German, Spanish, Portuguese, French). Subsequently, the initiative enticed further global contributions when the Russian, Mandarin and Arabic interfaces launched and again prior to the open-call end. In total, the initiative attained 3,775 contributions to the ASREM archive and 81 'Honorary mentions' quotes from 146 countries in 16 languages with over 500,000 unique visitors to the website. A number of articles by global journals also discussed and examined the objectives of this initiative, all of which provided further public engagement with this interstellar time capsule.

Interstellar communication is the transmission of signals between planetary systems. Sending interstellar messages is potentially much easier than interstellar travel, being possible with technologies and equipment which are currently available. However, the distances from Earth to other potentially inhabited systems introduce prohibitive delays, assuming the limitations of the speed of light. Even an immediate reply to radio communications sent to stars tens of thousands of light-years away would take many human generations to arrive.

The structure of the TAM was suggested by Alexander Zaitsev, Chief Scientist at Russia's Institute of Radio-engineering and Electronics. The message's content and target stars were selected by a group of teens from four Russian cities, who collaborated in person and via the Internet. Each transmission comprised three sections: a sounding, a live theremin concert, and digital data including images and text. TAM was humanity's fourth Active SETI broadcast and the first musical interstellar radio message.

Across the Universe is an interstellar radio message (IRM) consisting of the song "Across the Universe" by the Beatles that was transmitted on 4 February 2008, at 00:00 UTC by NASA in the direction of the star Polaris. This transmission was made using a 70-meter "DSS-63" dish in the NASA Deep Space Network's (DSN) Madrid Deep Space Communication Complex, located in Robledo, near Madrid, Spain. The transmission ran in the 4.2-cm band at a power of 18 kilowatt. The format was digital, transmitted at a rate of 128 kbps, lasting 3.6 minutes – the normal speed and data rate for a digital recording on Earth.

A post-detection policy (PDP), also known as a post-detection protocol, is a set of structured rules, standards, guidelines, or actions that governmental or other organizational entities plan to follow for the "detection, analysis, verification, announcement, and response to" confirmed signals from extraterrestrial civilizations. Though no PDPs have been formally and openly adopted by any governmental entity, there is significant work being done by scientists and nongovernmental organizations to develop cohesive plans of action to utilize in the event of detection. The most popular and well known of these is the "Declaration of Principles Concerning Activities Following the Detection of Extraterrestrial Intelligence", which was developed by the International Academy of Astronautics (IAA), with the support of the International Institute of Space Law. The theories of PDPs constitute a distinct area of research but draw heavily from the fields of SETI, METI, and CETI.

The cultural impact of extraterrestrial contact is the corpus of changes to terrestrial science, technology, religion, politics, and ecosystems resulting from contact with an extraterrestrial civilization. This concept is closely related to the search for extraterrestrial intelligence (SETI), which attempts to locate intelligent life as opposed to analyzing the implications of contact with that life.

Breakthrough Initiatives is a science-based program founded in 2015 and funded by Julia and Yuri Milner, also of Breakthrough Prize, to search for extraterrestrial intelligence over a span of at least 10 years. The program is divided into multiple projects. Breakthrough Listen will comprise an effort to search over 1,000,000 stars for artificial radio or laser signals. A parallel project called Breakthrough Message is an effort to create a message "representative of humanity and planet Earth". The project Breakthrough Starshot, co-founded with Mark Zuckerberg, aims to send a swarm of probes to the nearest star at about 20% the speed of light. The project Breakthrough Watch aims to identify and characterize Earth-sized, rocky planets around Alpha Centauri and other stars within 20 light years of Earth. Breakthrough plans to send a mission to Saturn's moon Enceladus, in search for life in its warm ocean, and in 2018 signed a partnership agreement with NASA for the project.

METI International, known simply as METI, is a non-profit research organization founded in July 2015 by Douglas Vakoch that creates and transmits interstellar messages to attempt to communicate with extraterrestrial civilizations. It is based in San Francisco, California.

Vakoch advocates ongoing transmission projects, arguing that this does not increase risks of an alien invasion as suggested by British cosmologist Stephen Hawking. He has participated in several SETI observation programs, and after sixteen years at the SETI Institute, where he was director of Interstellar Message Composition, Vakoch founded METI International. He has edited over a dozen books in SETI, astrobiology, the psychology of space exploration, and ecocriticism. He is general editor of two-book series in ecocriticism and in the intersection of space and society. Vakoch has appeared widely on television and radio as a commentator on SETI and astrobiology. He is an emeritus professor of clinical psychology at the California Institute of Integral Studies (CIIS).

<i>Archaeology, Anthropology, and Interstellar Communication</i> 2014 essay collection

Archaeology, Anthropology, and Interstellar Communication is a 2014 collection of essays edited by Douglas Vakoch and published by NASA. The book is focused on the role that the humanities and social sciences, in particular anthropology and archaeology, play in the search for extraterrestrial intelligence (SETI). The seventeen essays are gathered into four sections, which respectively explore the history of SETI as a field; archaeological comparisons for human-alien communication, such as the difficulties of translating ancient languages; the inferential gap between humans and aliens, and the consequences this would have for communication and trade; and the potential nature of alien intelligences.
