|A NASA Panel Says We Don’t Need to be so Careful About Infecting Other Worlds|
It’s time to update the rules. That’s the conclusion of a panel that examined NASA’s rules for planetary protection. It was smart, at the dawn of the space age, to think about how we might inadvertently pollute other worlds with Earthly microbes as we explore the Solar System. But now that we know a lot …

There’s a problem with Venus. We don’t know how fast it rotates. For a space-faring civilization like ours, that’s a problem. Measuring the length of day, or rotation rate, of most bodies is pretty straightforward. Mark a prominent surface feature and time how long it takes to rotate 360 degrees. But Venus is blanketed in …
