A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

That's why this is done: https://www.nasa.gov/ames/space-biosciences/planetary-protection/

I realize you were probably talking about visiting other worlds in person, but we would probably still have unmanned missions there first.

NASA is funny. They are always searching for signs of life, past or present, on planets in our system when they can send a lander of some sort. But, if there is a spot where there actually might be a chance of life existing, they avoid it because of the minuscule chance of some bacteria on any rover contaminating the area.

We’ll look for signs of life where it’s hard to find and avoid the areas where there might be a better chance of it.

NASA has been doing the sterilization I listed above for decades now; it's not new.

Can you give some examples (preferably with references) of where NASA (or ESA, etc) have avoided areas due to fear of contamination?
