Journal ArticleDOI
Gossamer-1: Mission concept and technology for a controlled deployment of gossamer spacecraft
Patric Seefeldt,Peter Spietz,Tom Sproewitz,Jan Thimo Grundmann,Martin Hillebrandt,Catherin Fiona Hobbie,Michael Ruffer,Marco Straubel,Norbert Toth,Martin E. Zander +9 more
TL;DR: The aim of the work presented here is to provide reliable technology that enables the controlled deployment and verification of its functionality with various laboratory tests, thereby qualifying the hardware for a first demonstration in low Earth orbit (LEO).
Journal ArticleDOI
Capabilities of GOSSAMER-1 derived Small Spacecraft Solar Sails carrying MASCOT-derived Nanolanders for In-Situ Surveying of NEAs
Jan Thimo Grundmann,Waldemar Bauer,Jens Biele,Ralf Boden,Matteo Ceriotti,Federico Cordero,Bernd Dachwald,Etienne Dumont,Christian Grimm,David Hercik,Tra-Mi Ho,Rico Jahnke,Aaron Koch,Alexander Koncz,Christian Krause,Caroline Lange,Roy Lichtenheldt,Volker Maiwald,Tobias Mikschl,Eugen Mikulz,Sergio Montenegro,Ivanka Pelivan,Alessandro Peloni,Dominik Quantius,Siebo Reershemius,Thomas Renger,Johannes Riemann,Michael Ruffer,Kaname Sasaki,Nicole Schmitz,Wolfgang Seboldt,Patric Seefeldt,Peter Spietz,Tom Spröwitz,Maciej Sznajder,Maciej Sznajder,Simon Tardivel,Norbert Toth,Elisabet Wejmo,Friederike Wolff,Christian Ziach +40 more
TL;DR: The philosophy of the Gossamer solar sail concept of efficient multiple sub-spacecraft integration to also include landers for one-way in-situ investigations and sample-return missions and the concept of Constraints-Driven Engineering for a wider range of operations is expanded.
Journal ArticleDOI
A stowing and deployment strategy for large membrane space systems on the example of Gossamer-1
Patric Seefeldt,Patric Seefeldt +1 more
TL;DR: The mathematical description of the stowing and deployment geometry, as well as the forces inflicted by the mechanism provides an understanding of how exactly the membrane deploys and through which edges the deployment forces are transferred.
Proceedings ArticleDOI
The Design and Test of the GOSSAMER-1 Boom Deployment Mechanisms Engineering Model
TL;DR: The main functional and geometrical requirements for the mechanisms are derived from the mission design and the global sail deployment concept which are both introduced in detail.
Proceedings ArticleDOI
Membrane Deployment Technology Development at DLR for Solar Sails and Large-Scale Photovoltaics
Tom Sproewitz,Jan Thimo Grundmann,Patric Seefeldt,Peter Spietz,Martin Hillebrandt,Rico Jahnke,Eugen Mikulz,Thomas Renger,Siebo Reershemius,Kaname Sasaki,Maciej Sznajder,Norbert Toth +11 more
TL;DR: Based on the Gossamer-1 experience, deployment technology and qualification strategies, new technologies for the integration of thin-film photovoltaics are being developed and qualified for a first in-orbit technology demonstration within five years.
