NASA's Planetary Protection Officer has suggested that it's time to contaminate Mars slightly aggressively before humans arrive with their microbiomes in tow:
Is there life on the surface of Mars? The clock is ticking on scientists' window to solve that long-standing question before astronauts—and the microbes that live on them—contaminate the planet. Today, at a meeting in Washington, D.C., of NASA's planetary science advisory committee, the agency's new planetary protection officer raised the possibility of opening up a few of the planet's most promising regions to more aggressive exploration.
Just a few weeks into the job, Lisa Pratt, formerly a geomicrobiologist at Indiana University in Bloomington, has signaled that she wants the office to be open to the notion that a degree of contamination might be necessary to explore several of the planet's most habitable spots. Previously, the office has served as a watchdog to prevent the contamination of Mars and other planets with microbes from Earth, and vice versa. But now, time is pressing, given NASA's long-term goals, Pratt says. "No matter what we do, the minute we've got humans in the area we've got a less pristine, less clean state," Pratt said at the meeting. "Let's hope we know before the humans get there, one way or the other, if there is an ecosystem at or near the surface."
Although no region of Mars is banned for exploration, international treaties set the allowable levels of microbial contamination on robotic spacecraft destined for other planetary environments. Some scientists say it is too costly to meet the sterilization requirements to explore the potentially warm and wet "special regions" on Mars that are most likely to harbor microbes. Only the 1970s Viking landers achieved the cleanliness necessary to explore a special region. A growing number of scientists have argued that the agency needs to rethink its plans, as Science reported last year.

On second thought, the article doesn't mention the exact conditions under which they opened the sterilized box. Perhaps there is more to the story and the engineers thought they were following adequate protocols if they did it in a very controlled environment or something. The text of that paragraph is vague though and makes the JPL engineers sound like a bunch of whiners who couldn't follow basic instructions and/or thought they'd "get away with" an obvious break in protocol.
(And, you know, I probably should give NASA engineers the benefit of the doubt. Except for the fact that in 1999, NASA lost the $125 million Mars Climate Orbiter because somebody forgot to convert feet to meters...)
