Space X launches first orbital laser satellites.

 Space X launches first orbital laser satellites. 

The purpose of V2 minisatellites is to offer 5G communication between satellites. This type of satellite can make many other things than offer just 5G communication between ISS (International Space Station) and satellites. There is the possibility that those laser satellites also can make observations about gravitational waves. And that thing makes those minisatellites interesting. The power that the laser uses determines its purpose. 

So communication satellites or some scientific satellites can turn into extremely powerful reconnaissance satellites. Those satellites can use their lasers as laser microphones. Or the same satellites can be killer satellites if those systems have no limits. The fact is that the same system that can adjust its laser's power can act as a civil satellite. 

The killer satellites might use solar power. And they can work as regular communication satellites until they get commands. Those hybrid satellites might use their lasers as communication tools. But when they face some kind of threat, those satellites increase their laser's power.

The moon can be an ideal place for radio and optical telescopes. 

The moonquakes can cause problems with optical telescopes. But the other side of the moon can protect the telescopes from the light and other electromagnetic radiation wich source is on Earth. The radio telescope. Or researchers send mock-ups to the Moon quite soon. 

The position of those systems would be the far side of the moon. The moon protects those radio telescopes against electromagnetic radiation, whose source is on Earth.  Radio telescopes don't require a stable base. The communication between those telescopes that are on the far side of the moon can happen by using an antenna that is on the Earth side of the moon and information travels between that antenna and radio telescopes by using optical fibers. 

In that project, the robot wagon can pull optical fiber and electricity between telescopes and solar panels that are on the Earth's side. The system requires two solar panel groups on both sides of the Moon. That makes it possible to deliver electricity to those telescopes all the time. If the control gives commands by using an antenna that is on the other side of the moon, and the information travels in cables that will not disturb those observation tools.
