Space Station Gets Some Company This Weekend

If you haven’t seen the International Space Station (ISS) at dawn I understand your reluctance. Perhaps two additional enticements will coax you out before sunrise. Problems with a new rendezvous system on the Russian Progress M15-M supply ship prevented a successful docking with the ISS Tuesday. Bad news, right? Well yes and no. Mission controllers put Progress in a safe spot 1.8 miles below the station until the next docking attempt Sunday. That means a few more mornings of seeing the two travel together across the sky.

Wait, there’s more. The Japanese Kounotori 3 or “white stork” cargo-carrying vehicle is on its way to the station to deliver food, equipment and a module to deploy five nanosatellites (very small satellites) into orbit. Before it docks tomorrow morning July 27, you might also be able to see it.

Though considerably fainter than the ISS, Progress and Kounotori 3 should be visible following a short distance behind.

Use binoculars to help you spot them. To improve your chances, point the binoculars a little ahead of where the station is moving, let it pass through the field of view and keep watching the spot you’re aimed at for 15-30 seconds after. If your sky’s dark enough you should be able to see them with the naked eye.

Next, we check in on the planets. 90 minutes to an hour before sunrise face east to get an eyeful of planets and star clusters. The Pleiades, Hyades, Jupiter and Venus are gathered together on the sky stage like musicians at a chamber concert.

But wait, there’s even more! This weekend before dawn we get a visit from the annual Delta Aquarid meteor shower. I’ll have details on how to watch it and what to expect in tomorrow’s blog.
