Speed up or slow down too quickly and it's lights… » 10/01/14 3:53pm 10/01/14 3:53pm

A Motor That Can Get To The Moon On A Few Drops Of Fuel

One of the biggest challenges of space travel is the immense fuel cost of traveling even to our own planet's satellite, let alone one of our neighboring planets.

And because our addled little brain is somewhat screwy when it comes to physics (we did well in Honors Bio but struggled through high-school Chemistry and didn't bother with physics if it involves math, forget it). And we could've saved… » 3/17/06 12:22am 3/17/06 12:22am
