Claim 0:
1. A coupling unit for detachable coupling of two parts of a spacecraft, wherein the coupling unit comprises:
a first element configured for fixed connection to a first part of the spacecraft, wherein the first element comprises a strut;
a second element configured for fixed connection to a second part of the spacecraft;
wherein the first element and the second element are engageable to each other in a connected condition;
wherein the strut of the first element, in the connected condition, is engaged inside of the second element by extending through a bore of the second element and is fixedly connected to the second element via at least one breakable fixation element;
wherein the second element comprises a gas generator that is configured to generate gas under pressure inside of the second element to break the at least one breakable fixation element and push the first element, including the strut, outside of the second element, so as to distance the two parts of the spacecraft, by complete separation of the first element from the second element;
wherein the strut is configured to guide the first element with respect to the second element after the at least one breakable fixation element is broken; and
wherein the second element is further configured to contain all of said gas, generated by the gas generator, within the second element.
