 Our alumna is up there today. I appreciate the music and hopefully we'll all smile around and let's start the flight, get some good pictures. Good morning to you Dr. Davis. How are things today? Good morning. Things are going well on discovery and it's a beautiful day outside on orbit. Let's talk about the current mission right now. You're studying what's happening to the Earth's ozone layer. That's correct. On flight day one we deployed the CRISPR-SPOS satellite and it's out there scanning the Earth's atmosphere from north to south and through several altitudes and we're looking at different chemicals and the different altitudes around the world to see where the ozone is and how much of it is there as well as other chemicals. Crew members yesterday tested out a new robotic arm. You're actually nearby the workstation where that robotic arm is controlled. It gave you a little bit of trouble. Where do we stand with that? I think we understand the complexities of what we did on flight day two. This is the workstation where we operated the robotic arm which is a Japanese robotic arm which will be part of the Japanese arm on the space station. These are the two hand controllers. We have a computer here which also controls the arm as well as some switches. The problems we had on flight day two were we think just the force torque sensor which tries to take out the forces and torques that were applied to the arm may have been reacting, overreacting a little bit so we're going to just turn that on at the very last minute when we grapple with the box that we're trying to take out of its bracket and we think it'll work just fine today. We're going to give it another try and it was flying just beautifully. The only problem we had was with that force torque sensor compliance. Now this is your third mission in space. Has the newness worn off at all? Are you able just to go to work every day and think about what you're doing or are you still a little bit amazed at what you get to do for a living? The first day on orbit I felt like I was right at home. This is a great working environment and I just love being up here. Of course the Earth is the Earth's atmosphere and the Earth's weather and everything is constantly changing so every day is different as far as what we can see on the ground and that's just always fascinating. It's just beautiful to watch the Earth go by and I wish we had more time to do that but it's really beautiful. We saw the storm windy in the western Pacific starting to form this morning. It's a huge storm and it was just awesome to view it from orbit. I want to just get to a personal level briefly. Your husband is also an astronaut. Have either of you been up on the same shuttle mission ever and have you had a chance to talk with him back on Earth? Well as a matter of fact we did fly together back in 1992 on Space Lab J. We were on different shifts but we did manage to pass each other in the interlock as we were going to work each day and that was really a great experience to be able to share that flight together. He was last on the Hubble mission one of the space walking astronauts and so I think we're both really glad that we have somebody we can share those experiences with and enjoy watching the other person pass by in space. I want to ask you a question about some of the other highlights of NASA this year talking about the Pathfinder mission to Mars. It's raised a lot of awareness and a lot of excitement really for exploring other parts of the solar system. Do you see in the near future maybe the next generation of astronauts, maybe the generation of astronauts to come after you setting foot on the red planet? Well I certainly hope so. Our country is a nation of explorers and we're always exploring unknown and I certainly believe that would be the next step and I'm really glad that we have all this information about the other planets and we can prepare ourselves for that trip to Mars someday so I hope that there's some kids out there up early in the morning watching TV that say well someday aspire to be astronauts walking on Mars. And Houston Discovery this is Bjarni here. I'm just about to set up the ice cap experiment and I've been completed the corp and the bubbles run and they completed all of those. This here little thing in my hand is the wave maker for the ice cap experiment. We have a thin film and we generate waves by driving this little wave maker to oscillate a little paddle inside the cell. And I better go down to do that because we get on with it. Thanks Bjarni.
