After a rain delay on Wednesday, SpaceX is poised to launch its first manned mission to the International Space Station with DM-2. Leo says that while critics say that money shouldn't be "wasted" on space exploration, Leo disagrees, saying that a tiny fraction of the federal budget goes to NASA and the Commercial Space Program, and the benefits of what we learn far outweigh what we spend, or the risk. And it always has.
Leo says that the Space X Falcon Heavy rocket launch, with two boosters automatically landing afterwards, was a triumph of engineering (even though one crashed in the ocean). The fun part was using Elon Musk's Tesla Roadster as ballast with a mannequin dressed in a spacesuit, playing Bowie's Space Oddity on the stereo. What a great test, and the PR stunt of the century for Tesla, with hundreds of thousands watching the live stream of StarMan orbiting the earth before heading off to Mars.
George hears that Elon Musk wants to launch satellites to give everyone Wi-Fi access. Leo says it's true. He wants 4,000 satellites orbiting the earth so that there's nowhere on earth that you can't get high speed internet. He wants to launch them through SpaceX. Leo says that one of the problems with satellite internet, however, is the latency because of the distance it has to travel back and forth twice for each packet of data. Better than nothing, mind you, but there is a cost. Google is taking a different approach with balloons in Project Loon.
