ASTEROIDSQUADS/iSSB – A SYNERGETIC NEO DEFLECTION CAMPAIGN AND MITIGATION EFFECTS TEST MISSION SCENARIO by Jan Thimo Grundmann, Stefano Mottola, Maximilian Drentschew, Martin Drobczyk, Ross Findlay, Ansgar Heidecker, Ralph Kahle, Elnaz Kheiri, Aaron Koch, Volker Maiwald, Olaf Mierheim, Falk Nohka, Dominik Quantius, Paul Zabel, Tim van Zoest.
The mission scenario AsteroidSQUADS/iSSB was developed in response to several of the Recommendations from 1st IAA Planetary Defense Conference which addressed need for deflection-related testing and campaign design, studies momentum transfer impulsive deflection techniques, development protocols responsibilities within existing space situational awareness civil defence infrastructures on a global scale. Several more recommendations put dangerous objects smaller than current threshold definition Potentially Hazardous Objects (PHO) focus. Throughout, increased international participation emphasized.
AsteroidSQUADS/iSSB is intended enable Serendipitous Quantitative Understanding Assessment Deflection Strategies. advantages efficiency modern small-satellite-derived design philosophies evolved improved interplanetary spaceflight are highlighted by using DLR Kompaktsatellit programme’s Standard Satellite Bus kit as study baseline. This spacecraft platform draws strongly experiences gained lessons learned small satellites BIRD TET. It also has been baseline choice many at DLR’s Bremen Concurrent Engineering Facility, it currently used AsteroidFinder under development.
A number circumstances today’s commercial scientific environment their own widely regarded detrimental or unpleasant situations: For some time now, an uneasy struggle between test flight requirements heavy launch vehicle sector, related costs risks, schedule pressures, public relations insurance contracting concerns, motivation payloads such flights. Also, realistic particular geostationary payload vehicles carries significant risk polluting most vital regions Earth-orbital with large targets that invite escalation debris collisional cascading (Kessler syndrome). In planetary science always difficult obtain funding missions towards less prestigious target solar system. missions, selection severely constrained cover fields possible given budget. Resulting designs push launcher performance limit require gravity-assists nearest planets. Accordingly, rather probes experience extended cruise phases, causing high radiation doses sensitive components operational cost. defence, few exceptions, lesson-learning so far restricted paper exercises. Though NEO surveys have generally made good progress resources assigned, even basic methods hardly explored beyond lab experiments. seeks benefit opportunities presented these situations when mere co-existence turned into synergetic advantage all potential participants, including branches community. employs flotilla simple multi-role directed suitable sub-PHO size practice brief but intense integrated exercise real space.
