Yesterday, the early birds got good deals on flatscreen TVs.
Today, rising early will get you a glimpse at space exploration on your computer screen.
A rocket carrying the Mars Science Laboratory is scheduled to lift off from Cape Canaveral, Fla., shortly after 7 a.m.
You can watch the launch online at ustream.tv/nasahdtv.
The geology lab, which is mounted on an SUV-sized rover, is going to Mars to look for "past or present conditions favorable for life, and conditions capable of preserving a record of life," according to NASA's mars program website.
To achieve this, the rover carries a device the name of which is sure to delight science-fiction fans -- a rock-vaporizing laser.
It also is equipped with lots of cameras, according to NASA, which means it'll likely beam images online once it lands on the red planet in August 2012.
