A Soviet Progress M-5 cargo spacecraft carrying fuel, supplies and mail docked Saturday afternoon with the orbiting Mir space station, Tass reported.

The official news agency said cosmonauts Gennady Manakov and Gennady Strelakov were shown on Soviet television with items that the supply craft was to carry back to Earth, including canisters containing crystals grown in space.Manakov and Strekalov boarded the space station in early August, replacing Anatoly Solovyev and Alexander Balandin.

Solovyev and Balandin, using a furnace in the special "Krystall" module docked to the Mir, produced 23 pure crystals from February to August. Authorities said the crystals were worth about $1 million each, and could make the current project the first profitable space mission.
