Because there are so many locations to be monitored, "this saves us a lot of time," says Itziar Irakulis Loitxate, the remote sensing lead for the International Methane Emissions Observatory, which is responsible for MARS.

We should prepare for these systems to have their own subjective experiences, including sensing pain caused by humans.

It is a remote sensing technique which uses lasers to measure distances and create 3D maps, Ms Sayer added.

More challenging, he says, are “remote sensing” satellites, which include those used for geographical or intelligence purposes.
