Note: First published online in Alien Contact #47. The bibliography of this issue in Alien Contact, Jahrbuch #1 2002 states that it was published as Appell für die bemannte Raumfahrt in #47, but as of 2018-10-16, the archived online version of issue #47 at archive.org shows that Appell für die bemannte Weltraumfahrt was used as a title. Alien Contact, Jahrbuch #1 2002 probably stated the variant title in the bibliography in order to make it consistent with the title used in the Jahrbuch on the story's title page.
