Fifty-four dispatches, then the desk went quiet.

Science filed every weekday for seven weeks — a rift crossing an Antarctic shelf, a feathered dinosaur's tail in amber, Cassini's last orbits, 160 new species out of the Mekong. Nothing has been added since. It is kept exactly as it was filed.

How long does it take to hear back?

A dozen of these fifty-four dispatches are about spacecraft — Cassini's last orbits, Dawn's images of Ceres, the Trace Gas Orbiter's first look at Mars. All of them quietly assume something the reports never spell out: nobody drives a probe. You send an instruction and you wait.

  • One-way time, and the round trip you actually wait
  • A range, not one number — the planets keep moving
  • Any distance you like, in kilometres
  • Nothing is sent anywhere; the sum runs on your device
