On Wednesday, JPL engineers will begin checking Curiosity's scientific instruments to see if they are functioning properly. The rover also will begin collecting images for its first panoramic photo.
Later this week, the rover will be reprogrammed. It currently contains flight software and needs to be switched over to ground software.
"It's like doing a brain transplant on the rover," JPL media representative Gaye Hill said.
NASA only "goes with what it knows" and just packs whats needed for these long trips
The Curiosity rover's on-board computer is a pretty low-power system. In fact, the iPhone 4S is four times more powerful.
