Exploration of Life and Organic Compounds in Space: Tanpopo Experiments and Astrobiology beyond
International Space Station (ISS) is about 100m wide, 70m long and weights about 420,000 kg. ISS is orbiting around Earth every about 90 minutes. Exposure Facility (EF) where the experiments can be done in space, is attached outside of ISS. Experiments named Tanpopo meaning dandelion is on progress on EF. In Tanpopo Experiment, we are testing how long can terrestrial microbe survive in space environment. We are also collecting particles in space using porous silicagel called aerogel. We are expecting particles from space including micrometeorite can be collected. There may be particles escaped from Earth. Tanpopo instruments were launched on 2015 and returned to the ground after one year exposure, analysis of which are now going on. We are expecting many to be learned. Mars is orbiting outside of Earth. There are new findings on Mars, which was considered to be dead. Hydrothermal system has been found in the satellite around the Saturn. Thousands of planes outside Solar System have been found. We are hoping to find extraterrestrial life to be found somewhere. We will discuss the future development of Astrobiology.
