Cargo spacecraft "Progress M-38"

Mission details:

• RKK Energiya's automated cargo vehicle Progress 7K-TGM No. 240 was launched on Mar 14, 1998 and named Progress M-38. Vehicle 240 is specially modified to carry the second VDU (Vynosnaya Dvigatel'naya Ustanovka, External Engine Unit) propulsion unit. If vehicle 240 is similar to the vehicle 209 (Progress M-14) which carried the first VDU in 1992, the unit is mounted externally on a special structure between the cargo module and the service module, replacing the OKD fuel section present on normal Progress vehicles. The crew will spacewalk to extract the VDU from Progress and place it on the end of a Sofora boom extending from the Kvant module. The VDU is used to provide attitude control capability for the station.
• Launch mass of Progress M-38 was 7007 kg. By 03:20 UTC on Mar 15 it had successfully completed its first two orbital maneuvers. It replaced Progress M-37 at the docking port on the Kvant module.
• Progress M-38 undocked May 15 at 18:44 UTC, freeing up the docking port on the Kvant module for the new cargo ship.
