Cheers and applause echoed through the NASA Jet Propulsion Laboratory late Sunday after the most high-tech interplanetary rover ever built signaled it had survived a harrowing plunge through the thin Mars atmosphere.
"Touchdown confirmed," said engineer Allen Chen. "We're safe on Mars."
The extraterrestrial feat injected a much-needed boost to NASA, which is debating whether it can afford another Mars landing this decade. At a budget-busting $2.5 billion, Curiosity is the priciest gamble yet, which scientists and government officials hope will pay off with a bonanza of discoveries.
"We are the only country that has ever done anything like this," boasted John Holdren, the senior advisor to President Obama on science and technology issues, who was in the JPL control room as Curiosity touched down. "Many new technologies had to work in perfect synchronization."
Minutes after the landing signal reached Earth at 10:32 p.m. PT, Curiosity beamed back the first black-and-white pictures from inside the crater showing its wheel and its shadow, cast by the afternoon sun.
"We landed in a nice flat spot. Beautiful, really beautiful," said engineer Adam Steltzner, who led the team that devised the tricky landing routine.
It was NASA's seventh landing on Earth's neighbor; many other attempts by the U.S. and other countries to zip past, circle or set down on Mars have gone awry.
