Priyanka Analogue astronaut

It is no longer just science-fiction. Humans are really working on concrete projects today in 2020, not only on the exploration but also colonization of space! We are thinking already of building a functional Moon Village by 2050. The Moon Village is an open concept proposed with the goal of a sustainable human and robotic presence on the lunar surface as an ensemble where multiple users can carry out multiple activities.

Since it is very difficult for humans to live in space for long periods (as it is, it's already complicated here on Planet Earth), a lot of research needs to be on surviving out there and hence space agencies are coming together and collaborating on various analogue missions that simulate space environments - such as lunar/martian villages.

The International Lunar Exploration Working Group (ILEWG) is a public forum sponsored by the world's space agencies (like NASA and ESA) to support international cooperation towards the exploration and utilization of the Moon. As part of research efforts towards the colonization of Moon and creation of a Moon Village (and eventually Mars), ILEWG founded the EuroMoonMars initiative. It comprises of field campaigns in Moon-Mars analogue environments – basically regions on Earth that resemble other planets/space bodies.

One such analogue environment is the Hawaii-Space Exploration Analog and Simulation (HI-SEAS). It is located at 2,500 meters in elevation on the slopes of Mauna Loa Volcano in Hawaii, and resembles the surface of the Moon with its lava caves and lava tubes. It is a great training ground for astronaut-simulation missions. Additional fact: HI-SEAS is owned by the founder of the International Moonbase Alliance (IMA), Henk Rogers, who is also world-famous for his work in video games (another person who has mixed Space and Art!) EuroMoonMars, IMA and HI-SEAS (EMMIHS) are collaborating on the EMMIHS campaigns that consist of scientific research, field tests, training and outreach activities.

Through the European Space Agency EuroMoonMars program, Priyanka was one of the six analogue-astronauts for the third mission, EMMIHS-III, a two-week mission in January 2020. She trained under the director of HI-SEAS, Michaela Musilova, as crew-commander. She also conducted research on several topics including navigation, lava-cave exploration, robotics, crew-psychology, geology, culture and art. She also designed the team logo.
