The Phoenix has been on Mars for one sol. Its nominal lifetime is 90 sols. So, what’s this “sol” thing that we keep talking about when we talk about Mars and the landers on its surface?

Tomorrow morning, at 2am, clocks throughout most of the United States will be set one hour forward. This ensures that everyone gets up an hour earlier. That means that they are supposed to go to bed an hour earlier, too. We call this annual exercise Daylight Saving Time. I wrote about […]

Back in October, I posted something about daylight saving time. For many years, DST has started here in the United States the first Sunday in April and lasted until the last Sunday in October.
