Ralf Faller

Ralf Faller studied aeronautic and space engineering at the Technical University of Berlin and has been a researcher in the Department of Space Operations and Astronaut Training at DLR in Oberpfaffenhofen since 1991. He started out in the Spaceflight Dynamics Department but moved to mission operations after seven years.

His duties included the supervision of orbit and attitude control systems as a subsystem engineer and the role of the flight director and project manager in a variety of space missions. These missions have included, among others, various scientific projects, such as ROSAT and EQUATOR-S, positioning of satellites for commercial organisations and government entities - such as Eutelsat and military - as well as well as the preparation and implementation of technology testing missions such as BIRD and PRISMA. His current responsibilities include robotic space and servicing missions. He is project manager for the ground segment of the DLR German orbital servicing mission, DEOS.

PRISMA Experiment Operations at GSOC

The goal of PRISMA is to demonstrate sensors and flight software needed to perform formation flight and rendezvous missions. With respect to future on-orbit servicing missions, PRISMA is a milestone in developing and demonstrating the required technologies in orbit. The experiment operations started after commissioning and separation of the two spacecraft, Mango and Tango, in August 2010 . The basic experiment programme is planned to last ten months, with an additional two months for an extended campaign. The first half of this timeline was successfully executed by the Swedish Space Corporation, and after the transfer of operations on 14 March it is now GSOC's turn to conclude the nominal first year of operations. Let's have a closer look at the project structure, the experimenter's contributions and the experiment operations to be conducted at GSOC. read more

PRISMA: Satellitenpaar Mango und Tango im Missionsbetrieb

Es war schon ein besonderer Moment, als das Deutsche Raumfahrtkontrollzentrum GSOC am 14. März 2011 den Missionsbetrieb von PRISMA übernehmen konnte. Obwohl für mich auch nach 20 Dienstjahren jeder Start einer Mission etwas Besonderes ist, so stellte diese Übernahme des Betriebs einer bereits laufenden Mission etwas Neues dar. PRISMA ist bisher in vielerlei Hinsicht ganz anders. Ziel dieser Mission mit den Satelliten Tango und Mango ist die Demonstration von verschiedenen Formationsflug- und Rendezvous-Szenarien mit Abständen bis auf wenige Meter. read more

PRISMA – Mango and Tango in mission operations mode

On 14 March 2011, the German Space Operations Center (GSOC) took over operations of PRISMA. Despite my 20 years of service, I must say that even though every mission launch is special, the transfer of operations for an ongoing mission has a very new ‘feel’ about it. PRISMA has been different in many ways. The aim of this mission is to demonstrate various formation flying and rendezvous scenarios at separations of as little as a few metres with satellites Tango and Mango. read more
