A Nasa rover named Curiosity is en route to Mars. In just a couple of days it's 154 million mile trip will come to end. This mission is being called NaSA's riskiest mission ever.
Scientists around the world are bracing for the "seven minutes of terror." From the time Curiosity enters Mars' atmosphere, it'll have about 7 minutes to go from 13,000 miles per hour to a complete stop.
While Curiosity attempts to land on the surface of Mars, the video cameras it's equipped with will capture the first filming of a landing on another planet. That's if it can stick the landing.
Those 7 minutes of terror leave a big margin for error. If anything goes wrong it could end with a crash landing. Meaning the 2.5 billion dollar science project would go up in smoke. If it lands successfully, it could help scientists determine if the red planet could possibly be suitable to sustain human life.
