Small, low-cost internet satellites that provide affordable internet to everyone on the planet. These are what Elon Musk wants to create next after working on reusable rockets, space capsules and electric cars since the early 2000's, according to The Wall Street Journal. The publication says Musk is in the early stages of collaborating with Greg Wyler, who founded O3b Networks and led Google's internet satellite venture until earlier this year. The duo (with Wyler now representing WorldVu, a company he also founded recently) apparently plans to launch a total of 700 internet satellites into space. They want each of those satellites to cost less than $1 million to build and to weigh less than 250 pounds -- a huge undertaking, seeing as the smallest models these days cost several millions and weigh at least 500 pounds.
