Russia's Progress M-28M resupply vehicle docked at the International Space Station early Sunday (July 5), two days after its launch.
"Guys, congratulations. Your cargo vehicle has arrived," Russian flight director Vladimir Solovyov radioed from the TsUP mission control.
"It feels like Christmas in July!" responded a station crew member.
Loaded with more than three tons of supplies, the Progress linked up with the space station's Pirs docking compartment at 2:11 a.m. CDT (0711 GMT) as the two craft were traveling about 251 miles (404 km) above the south Pacific, southeast of New Zealand.
The station's crew planned to open hatches around 5 a.m. CDT. The Progress will remain at the station for four months.
