How much money does Alexander Gerst have?

Data about celebrities' net worth usually comes from websites that sell traffic and have no access to any accounting. They calculate from profession, fame, and age, copy figures from each other, and cite no source; differences of several multiples between them are common. There is no published data on Alexander Gerst's income or net worth: individual ESA employees' salaries are not made public, and in Germany income data is part of the private sphere. The reliable answer, therefore, is that it is not known.

The geophysicist joined the European astronaut corps in 2009. In 2014 he flew to the International Space Station for the first time, in 2018 for the second time, and during that stay he became the first German to take command of the station. Afterward he remained linked to ESA, in the preparation of future missions and outreach work. His income therefore derives from the salary grade of an international employee, not from launch bonuses or shares in any company.

At ESA, astronauts are governed by the same pay scale as the rest of the technical staff, and no bonus is foreseen for spaceflights. Fame brings invitations, books, and lectures, but additional paid activities and advertising contracts require authorization for agency staff and are tightly limited, precisely because the credibility of public research depends on it. What this profession gives is a secure technical salary, enormous visibility, and an experience almost no one else shares.
