Residence lasts typically between one and three months, also distributed over multiple visits, depending on the complexity of the research project. The research projects can be carried out at ESAC (Madrid, Spain) and at ESTEC (Noordwijk, Netherlands). To offset the expenses incurred by visitors, ESA covers travel costs from and to the home institution and provides support for lodging expenses and meals.

During their stay, visiting scientists have the opportunity to interact with archive and mission specialists for questions on the retrieval, calibration, and analysis of archival data. In principle, all areas of space research covered by ESA science missions can be supported (the data must be publicly available in the archives). To ensure that technical expertise in the specific area of interest is available at ESAC or ESTEC, applicants should consult the table of expertise and contact the relevant scientists in their field of interest (this is very important). In case of doubts, write to the programme coordinators for assistance at arvp@cosmos.esa.int.
