Last week was the 28th National Space Symposium attended by over 3,000 space professionals. The keynote speech was given by Dr. Neil deGrasse Tyson, director of the Hayden Planetarium and the host of COSMOS. It is an inspiring forty minutes of speech by Dr. Tyson, followed by twenty minutes of Q&A. It is definitely worth listening to, especially in a time when NASA is quickly losing all of its funding. Enjoy!
