A laser that can beam data from Mars to Earth at 10 times the rate of current radio links will be sent to the Red Planet in 2009, say NASA scientists. The laser will be the first test of such technology in deep space and may usher in a new era of space communication.
"It is the next big thing," says Stephen Townes, deputy manager of the Mars Laser Communication Demonstration at NASA's Jet Propulsion Laboratory in Pasadena, California. "There is the promise we will be able to get high data returns with lower power and lower mass than the typical systems out there."
NASA's Mars Odyssey spacecraft currently boasts the highest data transmission rate at 128,000 bits per second. The new laser will beam back between one million and 30 million bits per second, depending on the distance between Mars and Earth.
