In this year of the summer Olympics, it is only fitting that NASA scored a gold medal when it “stuck the landing” on its Curiosity rover, the most ambitious lander ever sent to another planet. In the wee hours of Monday morning, space geeks (most wear that label proudly) celebrated the news that Curiosity had survived the so-called “seven minutes of terror.” Information sent to and from Curiosity when it arrived at the Red Planet took seven minutes to travel the same 354 million miles that the craft had spent more than eight months traversing, so Curiosity was left to accomplish the touchdown on its own. By the time its NASA handlers could have identified and reacted to any possible hiccups during the descent, Curiosity would already have joined the ranks of failed missions. Sixty percent of exploration missions to the planet have failed to complete their objectives, and if Curiosity's automatic landing had not worked perfectly, Mars would have gained a new crater.
