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.

Thanks for the link, which is cued to the beginning of the specific segment brought up by GP.
And for others who may be concerned about the NSFW warning -- unless I was missing something, there's no "cartoon nudity" in the segment discussed by GP and which is cued here. Earlier in the cartoon (before the linked segment), there is some cartoon nudity of a rather mild variety.

I skimmed through the thing and I think I found some nudity in later portions as well.
The warning had to be made because it could appear on screen, someone could rewind it, the boss could access the page and watch from the beginning (slow day at work), whatever the case may be.

Yeah, I didn't watch the whole thing, so maybe there's nudity later too.
I wasn't objecting to your warning, by the way -- just noting that the segment under discussion doesn't contain any nudity that I noticed. (I'd note that some people don't watch things labeled as NSFW because they actually are avoiding nudity, not just because the boss might be watching. I wanted to let people know the segment under discussion doesn't contain it.)

I saw several candles shaped like naked ladies. And, one female Martian was stroking a goat-like being in a suggestive way.
