Citizens of Philadelphia, beware: You may see a grown man whizzing by you on a skateboard, doing 20 mph. That would be PopSci staff photographer John Carnett, and in case you dont get a good look, its a souped-up, motorized board he built from the ground up.
all the components except the motor are pretty basic rc components, you can get a proper stock mountain board for about 300 buks, and you then just need a motor, esc, and controller.
NASA spent $420 million to send the Phoenix Lander to Mars last year. Festooned with state-of-the-art detection equipment, the rover's task was to scour the red surface in search of elusive Martian ice.

ive been saying this since i was 8. im like why must they limit their searching, life on other planets is not based on the same restrictions as we are on earth, has anyone seen andromeda strain, the "disease" did not even have dna.
