A Progress-M1 spacecraft was launched from Baikonur Cosmodrome in Kazakhstan this morning at 4:32 AM Baikonur local time (20 May 6:32 PM EDT). The mission uses vehicle (tail number) M1-255, with the flight designation Progress M 1-6 on the ISS-4P mission. The spacecraft is in a 234.5 by191 km orbit at a 51.67° inclination, with each orbit taking 88.49 min.

Progress M 1-6 is carrying more than 900 kg of propellant to refuel the Service (“Zvezda”) module. Also on board is food and water for the crew, equipment to be used to repair the atmospheric revitalization system and the thermal control system, flight-data files, and internal lighting equipment.

Progress M 1-6 will dock with the ISS on 22 May 2001 at 8:22 PM CDT at the aft axial docking port of the Service Module. After remaining docked for approximately two months, the Progress-M1 will be loaded with items to be disposed, undocked from the ISS, and commanded to perform a destructive reentry into the Earth’s atmosphere. Impact is in a remote section of the South Pacific.

This mission was the first to use a Soyuz launch vehicle equipped with modernized first and second stage engines. These advanced engines were developed to meet the logistics and resupply requirements of the International Space Station. This enhanced Soyuz launch vehicle will go into service as Soyuz/ST and will be equipped with a larger fairing currently
being developed on by Starsem.
