Cargo resupply ships are vital for space exploration. These days they bring food, experiments and equipment to astronauts on the International Space Station. And in recent years, it hasn’t just been government agencies sending these things up; SpaceX’s Dragon spacecraft and (just this week) Orbital Sciences’ Cygnus spacecraft brought up cargo of their own to station in recent months.
NASA just published a brief timeline of (real-life) cargo spacecraft, so we thought we’d adapt that information in pictorial form. Here are some of the prominent members of that elite group. Did we miss anything? Let us know in the comments.

It was intended to send crew and cargo together in one flight, but delays and a change in program priorities never allowed it to achieve that. According to NASA, versions of TKS (under the Cosmos designation) flew to the Salyut 6 and Salyut 7 space station. The cargo part of the spacecraft was also used for Russian base modules in the Mir space station and International Space Station. Credit: NASA/Wikimedia Commons
