were so joyous over the next hour that JPL Director Charles Elachi had to plead for calm in order to hold a post-landing press conference. He compared the team to athletic teams that participate in the Olympics.
• "This team came back with the gold," he said.
• The extraterrestrial feat injected a much-needed boost to NASA, which is debating whether it can afford another robotic Mars landing this decade. At a budget-busting $2.5 billion, Curiosity is the priciest gamble yet, which scientists hope will pay off with a bonanza of discoveries and pave the way for astronaut landings.
• "The wheels of Curiosity have begun to blaze the trail for human footprints on Mars," said NASA chief Charles Bolden.
• President Barack Obama lauded the landing in a statement, calling it "an unprecedented feat of technology that will stand as a point of national pride far into the

future."
• Over the next two years, Curiosity will drive over to a mountain rising from the crater floor, poke into rocks and scoop up rust-tinted soil to see if the region ever had the right environment for microscopic organisms to thrive. It's the latest chapter in the long-running quest to find out whether primitive life arose early in the planet's history.
• The voyage to Mars took more than eight months and spanned 352 million miles. The trickiest part of the journey? The landing. Because Curiosity weighs nearly a ton, engineers drummed up a new and more controlled way to set the rover down. The last Mars rovers, twins Spirit and Opportunity, were cocooned in air bags and bounced to a stop in 2004.
• Curiosity relied on a series of braking tricks, similar to those used by the space shuttle, a heat shield and a supersonic parachute to slow down as it punched through the atmosphere.
• And in a new twist, engineers came up with a way to lower the rover by cable from a hovering rocket-powered backpack. At touchdown, the cords cut and the rocket stage crashed a distance away.
• The nuclear-powered Curiosity, the size of a small car, is packed with scientific tools, cameras and a weather station. It sports a robotic arm with a power drill, a laser that can zap distant rocks, a chemistry lab to sniff for the chemical building blocks of life and a detector to measure dangerous radiation on the surface.
• It also tracked radiation levels during the journey to help NASA better understand the risks astronauts could face on a future manned trip.
• Over the next several days, Curiosity was expected to send back the first color
