This paper discusses the top-level mission architecture and trajectory design for these resource-return missions, comparing high-thrust trajectories with continuous low-thrust solar-sail trajectories. This work focuses on maximizing the economic Net Present Value, which takes the time-cost of finance into account and therefore balances the returned resource mass and mission duration. The different propulsion methods will then be compared in terms of maximum economic return, sets of attainable target asteroids, and mission flexibility. This paper provides one more step towards making commercial asteroid mining an economically viable reality by integrating trajectory design, propulsion technology and economic modelling. 2019 Conference: 5th International Symposium on Solar Sailing (ISSS 2019) Conference: 5th International Symposium on Solar Sailing (ISSS 2019)At: Aachen, Germany https://www.researchgate.net/publication/334964831_Responsive_integrated_small_spacecraft_solar_sail_and_payload_design_concepts_and_missions Fachbereich Luft- und Raumfahrttechnik OPUS4-10034 Konferenzveröffentlichung Grundmann, Jan Thimo, ; Bauer, Waldemar, ; Boden, Ralf Christian, ; Ceriotti, Matteo, ; Cordero, Federico, ; Dachwald, Bernd, Dachwald@fh-aachen.de; Dumont, Etienne, ; Grimm, Christian D., ; Hercik, D., ; Herique, A., ; Ho, Tra-Mi, ; Jahnke, Rico, ; Kofman, Wlodek, ; Lange, Caroline, ; Lichtenheldt, Roy, ; McInnes, Colin R., ; Mikschl, Tobias, ; Montenegro, Sergio, ; Moore, Iain, ; Pelivan, Ivanka, ; Peloni, Alessandro, ; Plettenmeier, Dirk, ; Quantius, Dominik, ; Reershemius, Siebo, ; Renger, Thomas, ; Riemann, Johannes, ; Rogez, Yves, ; Ruffer, Michael, ; Sasaki, Kaname, ; Schmitz, Nicole, ; Seboldt, Wolfgang, ; Seefeldt, Patric, ; Spietz, Peter, ; Spröwitz, Tom, ; Sznajder, Maciej, ; Toth, Norbert, ; Viavattene, Giulia, ; Wejmo, Elisabet, ; Wolff, Friederike, ; Ziach, Christian, Responsive exploration and asteroid characterization through integrated solar sail and lander development using small spacecraft technologies In parallel to the evolution of the Planetary Defense Conference, the exploration of small solar system bodies has advanced from fast fly-bys on the sidelines of missions to the planets to the implementation of dedicated sample-return and in-situ analysis missions. Spacecraft of all sizes have landed, touch-and-go sampled, been gently beached, or impacted at hypervelocity on asteroid and comet surfaces. More have flown by close enough to image their surfaces in detail or sample their immediate environment, often as part of an extended or re-purposed mission. And finally, full-scale planetary defense experiment missions are in the making. Highly efficient low-thrust propulsion is increasingly applied beyond commercial use also in mainstream and flagship science missions, in combination with gravity assist propulsion. Another development in the same years is the growth of small spacecraft solutions, not in size but in numbers and individual capabilities. The on-going NASA OSIRIS-REx and JAXA HAYABUSA2 missions exemplify the trend as well as the upcoming NEA SCOUT mission or the landers MINERVA-II and MASCOT recently deployed on Ryugu. We outline likely as well as possible and efficient routes of continuation of all these developments towards a propellant-less and highly efficient class of spacecraft for small solar system body exploration: small spacecraft solar sails designed for carefree handling and equipped with carried landers and application modules, for all asteroid user communities -planetary science, planetary defence, and in-situ resource utilization. This projection builds on the experience gained in the development of deployable membrane structures leading up to the successful ground deployment test of a (20 m)² solar sail at DLR Cologne and in the 20 years since. It draws on the background of extensive trajectory optimization studies, the qualified technology of the DLR GOSSAMER-1 deployment demonstrator, and the MASCOT asteroid lander. These enable 'now-term' as well as near-term hardware solutions, and thus responsive fast-paced development. Mission types directly applicable to planetary defense include: single and Multiple NEA Rendezvous ((M)NR) for mitigation precursor, target monitoring and deflection follow-up tasks; sail-propelled head-on retrograde kinetic impactors (RKI) for mitigation; and deployable membrane based methods to modify the asteroid's properties or interact with it. The DLR-ESTEC GOSSAMER Roadmap initiated studies of missions uniquely feasible with solar sails such as Displaced L1 (DL1) space weather advance warning and monitoring and Solar Polar Orbiter (SPO) delivery which demonstrate the capability of near-term solar sails to achieve NEA rendezvous in any kind of orbit, from Earth-coorbital to extremely inclined and even retrograde orbits. For those mission types using separable payloads, such as SPO, (M)NR and RKI, design concepts can be derived from the separable Boom Sail Deployment Units characteristic of DLR GOSSAMER solar sail technology, nanolanders like MASCOT, or microlanders like the JAXA-DLR Jupiter Trojan Asteroid Lander for the OKEANOS mission which can shuttle from the sail to the asteroids visited and enable multiple NEA sample-return missions. These are an ideal match for solar sails in micro-spacecraft format whose launch configurations are compatible with ESPA and ASAP secondary payload platforms. 2019 IAA Planetary Defense Conference Conference: IAA Planetary Defense ConferenceAt: Washington DC, USA 29.04-03.05.2019 https://www.researchgate.net/publication/335352701_Responsive_exploration_and_asteroid_characterization_through_integrated_solar_sail_and_lander_development_using_small_spacecraft_technologies Fachbereich Luft- und Raumfahrttechnik OPUS4-9730 Konferenzveröffentlichung Grundmann, Jan Thimo, ; Bauer, Waldemar, ; Boden, Ralf, ; Ceriotti, Matteo, ; Chand, Suditi, ; Cordero, Federico, ; Dachwald, Bernd, dachwald@fh-aachen.de; Dumont, Etienne, ; Grimm, Christian D., ; Heiligers, Jeannette, ; Herčík, David, ; Hérique, Alain, ; Ho, Tra-Mi, ; Jahnke, Rico, ; Kofman, Wlodek, ; Lange, Caroline, ; Lichtenheldt, Roy, ; McInnes, Colin, ; Meß, Jan-Gerd, ; Mikschl, Tobias, ; Mikulz, Eugen, ; Montenegro, Sergio, ; Moore, Iain, ; Pelivan, Ivanka, ; Peloni, Alessandro, ; Plettemeier, Dirk, ; Quantius, Dominik, ; Reershemius, Siebo, ; Renger, Thomas, ; Riemann, Johannes, ; Rogez, Yves, ; Ruffer, Michael, ; Sasaki, Kaname, ; Schmitz, Nicole, ; Seboldt, Wolfgang, ; Seefeldt, Patric, ; Spietz, Peter, ; Spröwitz, Tom, ; Sznajder, Maciej, ; Tóth, Norbert, ; Vergaaij, Merel, ; Viavattene, Giulia, ; Wejmo, Elisabet, ; Wiedemann, Carsten, ; Wolff, Friederike, ; Ziach, Christian, Flights are ten a sail - Re-use and commonality in the design and system engineering of small spacecraft solar sail missions with modular hardware for responsive and adaptive exploration 2019 6 70th International Astronautical Congress (IAC) 9781713814856 70th International Astronautical Congress (IAC), Washington D.C., United States, 21-25 October 2019 1 7 weltweit https://eprints.gla.ac.uk/202033/ Fachbereich Luft- und Raumfahrttechnik OPUS4-9001 Konferenzveröffentlichung Grundmann, Jan Thimo, ; Bauer, Wlademar, ; Borchers, Kai, ; Dumont, Etienne, ; Grimm, Christian D., ; Ho, Tra-Mi, ; Jahnke, Rico, ; Koch, Aaron D., ; Lange, Caroline, ; Maiwald, Volker, ; Meß, Jan-Gerd, ; Mikulz, Eugen, ; Quantius, Dominik, ; Reershemius, Siebo, ; Renger, Thomas, ; Sasaki, Kaname, ; Seefeldt, Patric, ; Spietz, Peter, ; Spröwitz, Tom, ; Sznajder, Maciej, ; Toth, Norbert, ; Ceriotti, Matteo, ; McInnes, Colin, ; Peloni, Alessandro, ; Biele, Jens, ; Krause, Christian, ; Dachwald, Bernd, dachwald@fh-aachen.de; Hercik, David, ; Lichtenheldt, Roy, ; Wolff, Friederike, ; Koncz, Alexander, ; Pelivan, Ivanka, ; Schmitz, Nicole, ; Boden, Ralf, ; Riemann, Johannes, ; Seboldt, Wolfgang, ; Wejmo, Elisabet, ; Ziach, Christian, ; Mikschl, Tobias, ; Montenegro, Sergio, ; Ruffer, Michael, ; Cordero, Federico, ; Tardivel, Simon, Solar sails for planetary defense & high-energy missions 20 years after the successful ground deployment test of a (20 m) 2 solar sail at DLR Cologne, and in the light of the upcoming U.S. NEAscout mission, we provide an overview of the progress made since in our mission and hardware design studies as well as the hardware built in the course of our solar sail technology development. We outline the most likely and most efficient routes to develop solar sails for useful missions in science and applications, based on our developed `now-term' and near-term hardware as well as the many practical and managerial lessons learned from the DLR-ESTEC Gossamer Roadmap. Mission types directly applicable to planetary defense include single and Multiple NEA Rendezvous ((M)NR) for precursor, monitoring and follow-up scenarios as well as sail-propelled head-on retrograde kinetic impactors (RKI) for mitigation. Other mission types such as the Displaced L1 (DL1) space weather advance warning and monitoring or Solar Polar Orbiter (SPO) types demonstrate the capability of near-term solar sails to achieve asteroid rendezvous in any kind of orbit, from Earth-coorbital to extremely inclined and even retrograde orbits. Some of these mission types such as SPO, (M)NR and RKI include separable payloads. For one-way access to the asteroid surface, nanolanders like MASCOT are an ideal match for solar sails in micro-spacecraft format, i.e. in launch configurations compatible with ESPA and ASAP secondary payload platforms. Larger landers similar to the JAXA-DLR study of a Jupiter Trojan asteroid lander for the OKEANOS mission can shuttle from the sail to the asteroids visited and enable multiple NEA sample-return missions. The high impact velocities and re-try capability achieved by the RKI mission type on a final orbit identical to the target asteroid's but retrograde to its motion enables small spacecraft size impactors to carry sufficient kinetic energy for deflection. 2019 20 IEEE Aerospace Conference Proceedings AERO 2019; Big Sky; United States; 2 March 2019 through 9 March 2019 1 21 10.1109/AERO.2019.8741900 https://doi.org/10.1109/AERO.2019.8741900 Fachbereich Luft- und Raumfahrttechnik
