NASA is set to land an exploratory vehicle on the planet Mars early Monday morning.
The nuclear powered, one-ton rover, called Curiosity, will hunt for evidence of microbes on Mars and harvest a host of data and images from the planet. But first it has to land safely, completing an 8-month journey.
NASA scientists say the landing of the Curiosity, which is traveling at a speed of 21,240 kilometers per hour, is the most challenging they have ever attempted.
If the landing is successful, Curiosity will begin unlocking clues about possible life on Mars.
