NASA illustration of a VBK-Raduga ballistic return capsule during final descent to Earth . The VBK-Raduga capsule was a reentry capsule that was used for returning materials to Earth 's surface from the space station Mir . They were brought to Mir in the Progress-M cargo craft 's dry cargo compartment . For return , the capsule would be substituted for the Progress ' docking probe before it left the space station , and then after the Progress-M performed its deorbit burn , the capsule was ejected at 120 km altitude to reenter the atmosphere independently . It would then parachute to a landing area in Russia . [ 1 ] Each Raduga was about 1.5 m long , 60 cm in diameter , and had an unloaded mass of about 350 kg . It could return about 150 kg of cargo back to Earth . Use of the Raduga reduced the Progress-M 's cargo capacity by about 100 kg , to a maximum of about 2400 kg . [ citation needed ] The European Space Agency studied a very similar system called PARES ( Payload Retrieval System ) , for use in combination with the Automated Transfer Vehicle . [ 2 ]
