A one-ton visitor from certainly wrapping up its first full day on mars. That's the nasa rover earlier this morning with a triumph for nasa and dozens of companies who help build it. Abc's clayton sandell has the story as made in america goes to mars. Reporter: For centuries, earthlings have wondered what martians might look like. From harmless -- ♪ to not so much. So, to help us answer big questions about real-life martians -- to look for signs of past or maybe present life -- nasa just hit a galactic hole-in-one. Touchdown confirmed! Reporter: Landing the biggest rover ever on mars in a high-risk plunge dubbed the seven minutes of terror. High-tech parachutes, rockets -- even this sky crane they'd never used before -- had to slow curiosity from 13,000 miles per hour to a full stop. It worked. And nearly all of this $2.5 billion mission "made in america." There's something uniquely american about what it takes to put a rover like th on mars. Reporter: What it takes are companies in 33 states coast to coast. Cameras? San diego, california. Reporter: To windsor, connecticut, pioneer aerospace made curiosity's parachute, a passing mars orbiter caught this, a one in a million image on its way down. In tennessee, trading the two-wheelers to help build something. This is a huge endeavour but god bless america because we did put something on mars. Curiosity will rove it. Seven minutes, clayton sandell. That is all for us now. Thanks for watching.
