new part of observation of space where we never trod before and every time we have done this as a species, we have discovered new things. joining us now is leroy chow, former nasa astronaut who commanded the international space station. thank s so much for being with us. this sounds amazing, like hubbell on steroids. tell me exactly what we might learn from this. sure, this telescope is very much more powerful than hubbell. it is primary mirror is six times that of hubbell s. it is going to be able to look further and deeper into the universe than ever before. we re not sure what we re going to find. we re going to find more exoplanets and be surprised by some of the things we discovered, just like we were with hubbell after it launched a little over 30 years ago. and if i m not mistaken, hubbell orbits the earth, this is going to orbit the sun. this is going into much deeper space to get a much deeper look.
