Now six hours from touchdown. The current distance is 50,241 miles, closing at 8,285 mph, an increase of 75 mph in the past hour as the planet's gravity tugs on the spacecraft.
The Curiosity rover, the six-wheeled robot the size of a car, has a mass of 1,982 pounds. It is 9 feet, 10 inches long, 9 feet wide and stands 7 feet tall once the camera mast is erected. Its wheels are 20 inches in diameter and the instrument-laden arm is 7 feet long. The craft is powered by plutonium in a radioisotope thermoelectric generator, a switch to nuclear away from the solar panels used on the Spirit and Opportunity rovers to provide longer life and greater capabilities.
The 10 science instruments include the Alpha Particle X-ray Spectrometer, Chemistry and Camera, Chemistry and Mineralogy, Dynamic Albedo of Neutrons, Mars Descent imager, Mars Hand Lens Imager, Mast Camera, Radiation Assessment Detector, Rover Environmental Monitoring Station, and Sample Analysis at Mars.
"We're about to land a rover that is 10 times heavier than (earlier rovers) with 15 times the payload," says Doug McCuistion, director of Mars exploration at NASA Headquarters. "Tonight's the Superbowl of planetary exploration, one yard line, one play left. We score and win, or we don't score and we don't win.

I hope it comes through intact.
