Life on the International Space Station (ISS) is a lot like living in a science home that never stops moving—because it orbits Earth. To keep astronauts supplied, cargo spacecraft bring deliveries, like space versions of delivery trucks.
A cargo ship called Cygnus XL undocked from the ISS on Thursday, March 12, 2026, at 7:06 a.m. Eastern time. Undocking means it carefully unhooks and slowly backs away, like rolling a cart away without bumping anything.
Cygnus brings useful supplies such as food packets, clean clothes, tools, and science equipment. The ISS is also a lab where astronauts run experiments that help us learn about how bodies change in space, how plants can grow, and how materials behave when gravity isn’t in charge.
When Cygnus leaves, it keeps working on its mission and also helps the station stay organized by carrying away things that aren’t needed anymore. Stories like this show how much teamwork and planning it takes to keep science going about 250 miles above Earth.
