NASA's InSight lander touches down on Mars


Before we send people to the red planet. Here's komo's Lisa Jaffe with more down confirm. Celebrations at NASA today as its insight spacecraft successfully landed on Mars ABC's Clayton Sandell joins us on the KOMO news line from mission control with more on this journey that started more than three hundred million miles ago and cleaned. This isn't the first mission to Mars, but it's really a historic one. Is there going to explore inside the red planet? That's right. Yeah. And all that sharing was great. It's like winning an interplanetary Super Bowl or something like that. They were very excited to everybody at NASA here today, basically said that this mission went absolutely flawlessly. We got the first image just a few minutes after insight landed basically proving that it's stuck the landing the first Mars landing in in six years. And now the science can begin what scientists hope to discover. Well, they have basically three different experiments that they're going to deploy here in the next coming weeks. I have to kind of look at this landing zone figure out where the best places to use this. Robotic arm placed the sensors just in in the right space is so that'll come in the next few weeks. But these sensors essentially one of the assize monitor measures Mars quakes, they can measure even impacts from meteorites. Another one is a heat sensor to measure, the temperature of the core of Mars and another one is set to measure, just how much Mars wobbles in space, and that is important to try and figure out whether or not the core of Mars is liquid or solid or a combination of those two things they're trying to figure all of that album, basically paints a picture of the interior of Mars and scientists tell us that that can help us. Learn not only how Mars formed, but how earth formed and perhaps how other rocky planets in the solar system formed billions of years ago. It's almost looking at a at a time capsule. Really because they're trying to find out. What happened how come Mars is no longer like earth because we used to be very similar. That's right. We we had atmosphere together in our early days. We have flowing water and all of these things that lead to life and things thriving on earth. But for some reason. About a billion years or so the Mars district things went for medically different. So scientists are hoping that insight will kind of unlock a few of those clothes and saw some of these mysteries. This took a long time to make this mission happen, how difficult was it? Because NASA saying they had to survive seven minutes of terror to touch down on Mars. Yeah. You know, it's it's kind of a daunting thing to think about this mission being planned and executed over the last seven years or so and then it all coming down to the seven minutes of terror. They call it. I mean this thing had to approach the Mars atmospheric. Just the right angle twelve thousand plus miles an hour, a full stop in just about six and a half, seven minutes and all of those things had to work. Just right. I mean, the parachute had deployed the right time, but retro rockets had the fire and clear away the heat shield, the landing legs come down, the retro rockets had the fire so many things and all of it was really out of their control because of that communication delay. There. No, real common control of the spacecraft. They basically have hundred on autopilot and trust in the programming trust in the work that they had done years in advance hoping that it worked, thankfully it. Did I talked to one of the chief principal investigators on this mission? And he told me during that seven minutes of terror chewed off pretty much all of his fingernail ABC's Clayton Sandell joining us from NASA Jet Propulsion Laboratory in Pasadena,
