Imitation of the STS-101 mission patch, which commemorates the third Space Shuttle flight supporting the assembly of the International Space Station (ISS). This flight's primary tasks are to outfit the ISS and extend its lifetime, and to conduct a spacewalk to install external components in preparation for the docking of the Russian Service Module, Zvezda, and the arrival of the first ISS crew. The Space Shuttle is depicted in an orbit configuration prior to docking with the ISS. The ISS is depicted in the stage of assembly completed for the STS-101 mission, which consists of the United States-built Unity module and the Russian-built Zarya module. The three large stars represent the third ISS mission in the assembly sequence. The elements and colors of the border reflect the flags of the nations represented by the STS-101 crew members, the United States and Russia. The NASA insignia design for Shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, it will be publicly announced.

BEWARE: This drawing is similar to the original patch (File:Sts-101-patch.png), but not identical.
