(CNN) -- A Russian unmanned cargo spacecraft has successfully docked with the International Space Station after missing an earlier attempt Friday, NASA officials said Sunday.
The Progress cargo vessel, a resupply craft, was trying to dock with the space station Friday when a technical problem occurred about 20 minutes before the scheduled docking time, NASA spokeswoman Lynette Madison has said.
The vessel flew about two miles past the space station.
Six people aboard the space station -- three Americans and three Russians -- were not in danger, Madison said.
The craft launched Wednesday from the Baikonur Space Center in Kazakhstan, the state-run RIA-Novosti news agency of Russia said.
It planned to deliver "fuel, oxygen, scientific equipment and video and photo equipment" to the space station along with food, water and personal items for crew members, the news agency said.
Progress resupply vehicles typically deliver supplies to the space station and haul away trash, burning up on reentry.
