"On Nov. 1, after learning that the drill bit box had been opened, Conley said she had the mission reclassified to one in which Curiosity could touch the surface of Mars "as long as there is no ice or water." Conley's predecessor at NASA, John D. Rummel, a professor of biology at East Carolina University, said, partly in jest: "It will be a sad day for NASA if they do detect ice or water. That's because the Curiosity project will most likely be told, 'Gee, that's nice. Now turn around.' " If water is found, Curiosity could still conduct tests from a distance with instruments including a laser and spectrometers."
"... what we would do is we would take a step back, and we would convene a panel of scientific experts to review the whole procedure, look at the amount of ultraviolet light that might've been hitting the drill bit that would be burning, you know, giving all those organisms sunburn. There are a small number of organisms on the rover, many, many fewer than there are on the palm of your hand. But there are a few. So we would convene this panel of experts. We'd look at the conditions at Gale Crater. We'd consider what the characteristics of this potential water or ice might be, and then that panel would decide how we should proceed with the potential to study that."
