The resupply Cygnus spacecraft reached the International Space Station on Tuesday morning, delivering some four tons of supplies to the orbiting laboratory, NASA said.

Northrop Gumman’s Cygnus resupply spacecraft successfully launched Tuesday, sending more than 8,200 pounds of critical cargo and NASA science investigations to the International Space Station (ISS).

Despite having only one fully unfurled solar array, the Cygnus spacecraft safely arrived at the ISS on Wednesday at 5:20 a.m. ET, according to a NASA blog post.
