A very cool idea, however the headline is misleading - NASA has not even remotely committed to running this mission. They’ve selected the swarm project as one of 13 projects in their innovation program and given it up to $175k to study feasibility. That’s roughly a postdoc for two years. This is far, far from committing the hundreds of millions or billions needed for the execution of this mission.
