Protocols For Encounter With Extraterrestrials: lessons from the Covid-19 Pandemic by John W. Traphagan and Ken Wisian: This paper examines the lessons that may be learned from the Covid-19 pandemic that may be applied to contact with Extra-Terrestrial Intelligence. The pandemic is a parallel situation because Contact would potentially pose a threat to the whole population of Earth, compelling nations to take similar measures to each other to deal with it. Local social and cultural circumstances will affect the responses of various governments to Contact. Comparing such varied responses to the Coronavirus pandemic is a way of exploring how other situations might be met.

Water And Air Consumption Aboard Interstellar Arks by Frédéric Marin and Camille Beluffi:  The design of a multi-generation spaceship is dictated by the needs of the crew/colony for food, water and breathable air, which must be produced on board. This article uses simulation techniques to estimate such needs, and reviews methods for generating water from waste gases to complement the biospheres aboard multi-generational spaceships.



Habitability Of M Dwarfs: a problem for the traditional SETI by Milan M. Cirkovic and Branislav Vukotic: The authors consider that the flaring nature of M-dwarf stars would make the habitable zones around them difficult areas for the development of radio communication, and thus other methods than radio listening are needed to search for intelligent life forms living around such stars, whose cultural evolution would be shaped by their environments.

On A Spectral Pattern Of The Von Neumann Probes by Z. Ozmanov: This paper shows that the manufacture of von Neumann probes from interstellar matter would generate signals in the infrared and ultraviolet spectral bands, which might be a way to identify locations where such probes are being created by advanced civilisations.


Reworking the SETI Paradox: METI’s Place on the Continuum of Astrobiological Signaling by Thomas Cortellesi: The Search for Extraterrestrial Intelligence (SETI) has until now been a passive exercise, but some advocate an active approach. Messaging Extraterrestrial Intelligence (METI) is controversial, due to fears of potential risks; the author argues that such fears are illogical, and that passive SETI has a low chance of success.

Dynamic Vacuum Model and Casimir Cavity Experiments by Harold White, Paul Bailey, James Lawrence, Jeff George and Jerry Vera: This paper summarizes an interpretation of quantum mechanics that claims that the quantum vacuum can vary spatially and temporally, with implications to propulsion both as a sub-light drive mechanism and as a generator of wormholes or space warps.
