It's been 50 years since humans first landed on the Moon and we haven't done much there since. But Elon Musk is hoping that will change very soon. He already believes there should be a base on the Moon to fire up public interest in space exploration. Then in December, President Donald Trump announced that he wanted to send astronauts back to the moon as a first step toward more distant objectives, such as Mars, where Musk is already planning to land humans sometime within the coming decade.
Musk has also said that his company SpaceX would not build a moon base although it might ferry people and materials there from Earth. But it apparently is ready to help with something else every lunar visitor needs: a way to contact people at home, communicate with other lunar visitors--and watch Netflix during off hours.
So SpaceX, along with mobile network company Vodafone, Nokia, and Audi, will be building a 4G network on the moon in 2019. Even though 5G networks are being built here on Earth, the partners chose 4G because its technology is both more stable and more able to withstand space travel.
OK, but why build a wireless network on the Moon so soon, when nobody lives there? It's true that Musk has said he would take space tourists to the moon in late 2018, and indeed had already collected large deposits from two wealthy individuals for the first such trip. But the planned trip is only a Moon fly-by with no landing, so the lunar tourists won't get much of a chance to use the Moon's wireless network. And they won't need it, having the ship's communication system at their' disposal. Besides, the pricey lunar fly-by was meant to take place using a Crew Dragon capsule carried by a Falcon Heavy rocket, the same rocket that spectacularly took off earlier this month with a red Tesla Roadster and mannequin dubbed "Starman." But Musk has said SpaceX is now focusing its attention on its BFR Rocket (for Big Fucking Rocket) and he indicated it may not do much more testing on the Falcon Heavy after all, possibly leaving Moon tourism in limbo.
According to one report, the purpose of lunar 4G would be to support future lunar missions. Without it, humans and vehicles (such as the lunar rovers Audi is building) could only communicate by beaming signals down to the Earth and back up again. The fact that the planned network will have enough bandwidth to support video streaming raises the appealing prospect of a lunar webcam all of us could watch over the Internet.
And of course, it'll come in very handy for space tourists visiting the lunar surface or astronauts working to build a Moon base or on other projects. Maybe someday soon.
