Flying people to Mars won’t be easy. They’ll have to fly on a 3-year, 60-million mile trip to the right place, and then land on the ground safely. With the air so thin on Mars, you can’t land a spacecraft like you would an airplane. So NASA’s improvising. Click “Read More” to find out how, and do the math!

You’ve probably heard of biking to work, but biking at work is a whole other story.  A recently invented work desk, called the WeBike, makes people work for their, well, work.  As you sit at your desk, you pedal the bike, which generates the electricity to power your laptop, printers, phones, and other electronics.  It seems like kids could use this thing even more than adults, to power all the batteries you need for your toys.  And imagine if you had these bikes at school…could it do your homework for you?

Until pretty recently, when you wanted to find your way somewhere, you had to pull out a paper map, face it the right way, figure out where you were on the map, and then figure out how to get to your destination.  Now we’ve taken all the fun out of it.  With the digital maps on our smartphone and computer screens, you just type in your start and end points, and it draws the path you should take.  Then geopositioning systems, or GPS, use satellites to find you and plop a blinking dot on the screen to show you exactly where you are.  Now when taking a trip by car, thanks to GPS the days of crumpled maps are over.  But as we’ll see here, when it comes to timing, sometimes the system doesn’t know everything.
