According to the Associated Pres, Star City Mission Control spokesman Valery Lyndin said the unmanned Progress M-01M cargo ship has a new main computer and features a fully digital telemetric system along with other improvements.
Lyndin says the Soyuz-U booster rocket carrying the ship lifted off as scheduled at 3:38 p.m. (1238 GMT) Wednesday from the Baikonur.
He says the ship is set to dock at the station Sunday.
