Will humans live, work and thrive on Mars? What challenges must be met before we can become Martians? On July 20th, the anniversary of the Apollo 11 moon landing, Mat Kaplan welcomed an outstanding panel of experts for conversation in front of a Pasadena, California audience. Mat also talked with the six men and women who are nearing the end of the eight-month HI-SEAS V Mars analog mission in Hawaii. Later, Bruce Betts arrived on stage with another examination of the current night sky, along with a new space trivia contest.
