KSC-05-S-00280 (08/24/2005) --- Now here live to talk about launch day and all the preparations leading up to it is MRO Launch Director Chuck Dovale. Thanks for taking time to be with us, Chuck. Thank you, it's great to be here, Tiffany. Launching any rocket is an extremely complex process. Since this is NASA's first launch aboard the Atlas V, were the launch preparations very different? They were quite different for us. As you mentioned, this is the first Atlas V for NASA, as well as the government. Our last Atlas launch was an Atlas II several years ago. Read more...

KSC-05-S-00267 (08/18/2005) --- HOST TIFFANY NAIL: Once the Mars Reconnaissance Orbiter reaches its destination, then scientists at NASA's Jet Propulsion Laboratory in California will have a new and powerful observer of the Red Planet. Here to answer your questions about this important mission is Deputy Project Scientist Dr. Sue Smrekar. Thanks so much for joining us today. I'm happy to be here. With the launch of this mission so close, what are your thoughts as you see all the hard work of so many people ready to come to fruition? Well, a number of us have been working on it for at least four or five years, and many have been planning for a lot longer than that. Read more...

KSC-05-S-00265 (08/18/2005) --- Aren from Vermont: The twin Mars rovers are exploring only two of what I assume are several potential future sites. Is there already a long list of sites for MRO to scout, and if so, how will this spacecraft help you narrow down that list? There are hundreds of sites already on the list. People have been studying Mars for, you know, 20 years or more now, and a number of places have been identified that are interesting in the geology. They are sites where we think there may have been, where we can see that there was water in the past. Read more...

KSC-05-S-00264 (08/18/2005) --- Jeanette from Kane: Since one MRO objective is to search for and find a location suitable for future human exploration, what requirements or characteristics would such a site meet? Okay, well, the first thing is safety. The first thing we'd look for is a place that is not so rocky or doesn't have steep cliffs that it would be a problem for the vehicle landing. So, it's got to be safe. We'd want to know something about the environment. We might want to go near the equator where the temperatures are fairly uniform and relatively high for Mars. Read more...

KSC-05-S-00263 (08/18/2005) --- Elias from Sao Paulo: Can you explain how the sounder that is among the instruments of the MRO works? Also, how can it find or look for subsurface waters in Mars? Okay. Well, probably most people have seen like an ultrasound image. When mothers are pregnant, often these days ultrasounds are done. And it's the same kind of concept. You have waves that travel inside a solid body, but there are different places where the properties change. So when you look at a picture of a baby, what you see mainly are the bones. Read more...

KSC-05-S-00262 (08/18/2005) --- Ifikratis from Athens: Are there any concerns for the deploying of the SHARAD radar as there were for the Mars Express MARSIS? Also, I would like to know if the SHARAD would be better in terms of depth and quality measurements than the Mars Express Orbiter. Okay. Well, the two instruments are both built by the Italian Space Agency, and there are many overlapping aspects of the design. The main difference is the frequency. The SHARAD antenna on our mission is shorter frequency and the MARSIS antenna is longer frequency. Read more...

KSC-05-S-00261 (08/18/2005) --- Judy from Athol: On August 27, the Earth will be as close to Mars as it ever gets. Earth will not be this close again until the year 2287. How much travel time will this save compared to other launches? Also, and will the pictures sent be clearer because of its nearness? Okay, well, in terms of the last part of the question, will be pictures be clearer? No, not really, because we don't really take pictures until we get to Mars. So the fact that Mars starts out being close to the Earth doesn't really help us. Read more...

KSC-05-S-00260 (08/18/2005) --- Our next question comes from Junichi from Niihama City. Since the astronomy -- I'm sorry, since the atmosphere of Mars is not very dense, is MRO going to observe the surface of Mars in high-resolution pictures, especially over the poles? Yes, we will. In fact, the fact that the atmosphere is not very dense actually helps us. The more atmosphere you have to look through, the more it can distort your images and other data. So, the fact that it's, it's less dense is a great thing in terms of looking at the surface. Read more...

KSC-05-S-00259 (08/18/2005) --- Justin from Falmouth. He asked, what will be the MRO's first science mission after achieving orbit around the planet? Also, he asked, how long will it be before you receive any observations from the MRO when it arrives at Mars? Okay, well, as we spoke about, when we get to Mars, we spend six months aerobraking. So, during that time, we don't take any data. And then we go into opposition; that is where the Sun is between Earth and us. We can't actually transmit very much data. So, we're hoping that we'll be able to take some data fairly soon after aerobraking. Read more...

KSC-05-S-00258 (08/18/2005) --- Our next question comes from Juan from Gijon and he says hello, and he asks: How, have you considered taking pictures of the pathfinder Viking and MER landing sites? What about lost Martian probes like the Polar, Mars Polar Lander, or Beagle-2? Yeah. We can't wait to look at the landing sites with our resolution instruments. It will be, you know, very exciting to look at the surface and see tracks of the rovers and be able to, it actually provides very important data both for understanding the landing sites and for us because the rovers have been on the surface and looking close-up with a whole suite of instruments. Read more...

KSC-05-S-00257 (08/18/2005) --- Pawan also has another question. Could you explain more about the experimental navigation camera and how it is different from the other cameras that the MRO is carrying? Sure. Well, the optical navigation camera, its goal is to be able to send future spacecraft, we're not actually using it for our spacecraft navigation, but it's basically testing out this technology. And its goal is to be able to look at the moons of Mars -- Phobos and Deimos -- and use the information about where the spacecraft are in orbit around Mars, to be able to pinpoint where the spacecraft is very carefully. Read more...

KSC-05-S-00256 (08/18/2005) --- Pawan from Sharjah: The spectrometers on MER-A and B split the visible light into many colors which identify minerals. How is the spectrometer on the MRO different from the ones on the two rovers? Okay. Yeah, on the rovers there are actually three different spectrometers looking at a whole bunch of different parts of the spectrum. One looks at, it's called the Moessbauer spectrometer, and it looks in the part of the spectrum that is particularly sensitive to iron minerals. Another is the APXS, the alpha-proton X-ray spectrometer, and as that implies, it looks for those types of particles, X-rays, protons, so that can see a certain part of the spectrum and identify certain kinds of minerals. Read more...

KSC-05-S-00255 (08/18/2005) --- Our next question comes from Palak from Chicago. How will the Mars Reconnaissance Orbiter find out about the ground's chemical components from orbit? Okay. Well, we have a spectrometer onboard, and as the name implies, it uses the spectrum of light to look at the surface in a range of wavelengths. You've probably seen light go through a prism and split into a range of colors.The spectrum of light in the visible wavelength actually has a whole bunch of different colors at different wavelengths. Read more...

KSC-05-S-00254 (08/18/2005) --- Pawan from Sharjah asked us, what type of orbit will MRO be sent into once it reaches the Red Planet? Also, will it be used as a link by the MER-A and MER-B for sending data? Most spacecraft that have been in orbit around Mars to date, they have moved above the surface at an altitude of about 400 kilometers. Our orbit is going to be about two-thirds of the height of that, of the previous spacecraft. So our orbit is going to be at about 350 to, sorry, 255 to 320 kilometers above the surface. Read more...

KSC-05-S-00253 (08/18/2005) --- Victoria from Mount Vernon: What keeps the satellite's solar panels from burning up? Okay, that again goes back to this question of aerobraking and orbit insertion. And it's a constant adjustment as we're aerobraking to make sure that we don't get too deeply into the atmosphere. The deeper you go into the atmosphere, the more dense it is and the more friction and more heating you get during that time period. So during the phase where we're aerobraking, there are people constantly monitoring the spacecraft and making sure we don't go too deeply down and making sure that the spacecraft is healthy. Read more...

KSC-05-S-00252 (08/18/2005) --- Mary from White Plains: Can you explain how the six months of aerobraking works and why it's necessary? When we aerobrake the spacecraft, it's a lot like putting the drag flaps up on an airplane. As an airplane comes in to land, it puts the flaps up on the wings, and it changes the shape of those wings from being a very smooth, aerodynamic surface to something that's really resisting the air and acting like a brake. And we did the same thing with our spacecraft, we fully deploy the solar arrays. Read more...

KSC-05-S-00251 (08/18/2005) --- Our next question comes from Pawan from Sharjah. If the spacecraft fails to slow down to some malfunctioning, what are the backup plans of the scientists for this problem, or, if the spacecraft can not be captured into orbit around Mars? Well, orbit insertion around Mars is probably the most critical event. Perhaps launch is the most critical, and then insertion into orbit around Mars is the next most critical. And there really is no way to recover from a significant problem there. There's a very narrow window in terms of getting close enough to Mars so that you don't shoot right past it, but if you get too close then this spacecraft overheats and it can be damaged, even burn up in the atmosphere. Read more...

KSC-05-S-00250 (08/18/2005) --- With so much interest in the exploration of Mars, our NASA Direct question board has had quite a response. Are you ready to answer a few of our viewers' questions now? Sure. Let's go. Let's get started. Our first question comes from Patrick, and he's eight years old and he's from Telford. Why is it so important that the rocket has to be launched within just two hours on Aug. 10? What does it mean when you say that Mars is in opposition to Earth? Okay, well, I think I'll answer the opposition part first. Read more...
