Located 254 miles above the Earth's atmosphere, the ISS is inhabited by astronauts from Europe, the United States, Canada, Japan and Russia, working on hundreds of experiments in biology, physics, medicine, materials science, education and technology.

Dr. Castaño has focused on a group of experiments on human health (a study of twin astronauts in the field of genomics and other studies of physiological deconditioning in response to the space conditions), plant biology (comparing US and Russian plant growth studies), and the study of particles in the Universe (NASA's Alpha Magnetic Spectrometer and JAXA's Calorimetric Electron Telescope), researching how they are executed and evaluated at every stage of the process.
