While we haven't found any aliens quite yet, NASA scientists may be locating the best places and ways to look for aliens in future missions to space.
Most scientists are super excited about finding alien life, but some people, like Stephen Hawking, think it's a bad idea to try and seek them out. He's afraid that the aliens will be far more advanced and will try and colonize our planet. For the most part though, cosmologists say they are prepared to discover any kind of life.
NASA scientists are currently considering 28 different plans for future missions with the sole purpose of seeking out life. Many people probably think that we should be focusing efforts and money on problems closer to home, but astrobiologists think that the search for life is in other worlds should be our focus in terms of the solar system.
This relates back to the robonaut article too, because many of the planned missions include sending robots into space. Probably humans would be better suited to perform research, but sending robots definitely have fewer risks.
