Workshop aims to provide an introduction to the fascinating world of tardigrades and their relevance in astrobiology. Through a combination of lectures and hands-on activities, participants will explore the biology of these microorganisms, known for their ability to survive extreme conditions, from freezing temperatures to exposure to the vacuum of space.

Their role in astrobiological research will be discussed, highlighting experiments conducted in space and their potential to aid in the search for extraterrestrial life. Water bears, also known as tardigrades, are very small, segmented animals. The largest species is just over one millimetre in length. Water bears live in temporary ponds and droplets of water in soil and on moist plants. They are known to survive under conditions that would kill most organisms – they can withstand temperatures ranging from -272 deg C to +150 deg C, they can be without water for a period of 10 years, and they are extremely resistant to radiation.

In addition to theoretical lectures, the workshop will include a field trip around the Molėtai Astronomical Observatory, where attendees will collect samples from potential tardigrade habitats. Later, in the laboratory, they will learn how to locate and isolate these organisms for microscopic observation, identifying their characteristics and structures while also learning how to cultivate tardigrades at home.

This workshop is designed for university students, researchers, and enthusiasts of microbiology and astrobiology, offering a unique opportunity to understand how extremophiles can provide insights into life on other planets. With a practical and accessible approach, participants will learn about tardigrades and experience their search and analysis firsthand in a real scientific environment.
