Progress M1-4

 2000-073A

---

Progress M1-4 was launched to Zarya's nadir port. A software problem with the Kurs system sent Progress into oscillations at a range of 100m. Gidzenko took TORU control but the camera iced up; he backed it off until the picture improved and then came back in for a successful manual remote docking.

The Progress was quickly unloaded and then undocked prior to the STS-97 approach on Dec 1. Loaded with improved software, the craft made a flawless second approach on Dec 26. The Kurs close-approach antenna had been irreversibly retracted on the initial docking, so the final approach had to be done with TORU again. Gidzenko took TORU control and brought the craft in to a docking, once again at the Zarya nadir.

Launch mass was 7285 kg. It carried 874 kg of propellant (760 kg in OKD and 114 kg in GO or PAO?). GO cargo was 1358 kg, assume 1244 kg of it was dry.
