    Saved you a click: it’s from a human made craft, roughly 40x Earth-moon distances away.

    They expect to reach bandwidths 10-100x what is currently possible with radio waves. However, it requires very precise alignment, and more importantly, requires taking into account the relative movement of the sender and receiver.

    This craft is headed further away up to where they expect the communication delay to be around 20 minutes, up from the current 50 seconds.

    absolutely impressive!

    How can anything aim with such precision?
