Is it better to live on the moon or on Mars? A scientific investigation

If humans needed to beat a retreat from planet Earth, would it be better to live on Mars, or on the moon?| Long Read

Elon Musk wants humans to live on Mars. NASA wants, at the very least, to send some astronauts over to the Red Planet to check it out. But the Trump administration has recently signaled that it’s more interested in sending astronauts back to the moon.

As a space science professor, I believe this is the perfect opportunity to revive an important debate: If humans needed to beat a retreat from planet Earth, would it be better to live on Mars, or on the moon?

First, let’s consider the advantages of Mars.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
