| Carl Sagan's COSMOS is one of the most influential science programs ever made.
Q. Does the moon have a dark side?
A. The moon does have a far side which is impossible to see from the earth, but it doesn't mean that it's always dark. Each side of the moon is dark for no longer than 15 days at a time.
Q. Where does sound come from?
A. The air is always filled with sound waves. All things give off vibrations, but some have a low frequency which most cannot hear. The reason: it may take 3 minutes to make a single vibration. They may be caused by earthquakes and storms.
Did You Know?
The microwave was invented after a researcher walked by a radar tube and a chocolate bar melted in his pocket.
Coke-a-Cola was originally green.

Telerobotic equipment aids in cleanup activities
by Fred Strohl of DOE/Oak Ridge National
Laboratory
OAK RIDGE, Tenn., Nov. 14, 2002 – Researchers at Oak Ridge National Laboratory are developing robotics technology that can aid in the cleanup of hazardous waste sites while helping to protect humans from serious injury in the process.
The telerobotic manipulation system enables cleanup efforts to be conducted remotely from a distant location, performing chores that would have to otherwise be done on site by humans.
Developed by the Department of Energy's Robotics Crosscutting program, the system may be used in the future to clean up hazardous waste sites under DOE's jusrisdiction and may have additional future uses for various cleanup tasks.
The compact remote control console, which is the front end of the system, provides the operator with the ability to manipulate the telerobot that performs the actual cleanup work.
It includes four monitors for remote task viewing, two touch screen-based graphical user interface computers, a telerobotic control computer and hand controllers to command the robot manipulator to complete cleanup tasks.
The compact console was developed by DOE specifically to control costs related to deploying remote systems while maintaining a control room level of capability. Several compact consoles have been used around the United States for various cleanup tasks. The compact console component of the telerobotic manipulation system is now available commercially from Agile Engineering of Knoxville.
The telerobotics part of the system combines human input (teleoperation) and robotics automation – hence telerobotics – to complete cleanup tasks. The current focus is plasma arc cutting of metal structures to dismantle contaminated equipment.
Testing of the equipment comes during a time when there is an increasing need for remote systems and robotics for cleanup of DOE facilities.
