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 …

Time-lapse Captured from the International Space Station

400 photos. 11 minutes. That’s what it took to create this time-lapse of the Earth and stars as the International Space Station over Namibia toward the Red Sea. NASA astronaut Christina Koch captured these images. It’s obvious that the circular streaks in the sky are star-trails. But the lights on the ground have different sources. …

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 …
