NASA's Dragonfly Program: Commercialized Robotics
35th Space Symposium, Technical Track, Colorado Springs, Colorado, United States of America Presented on April 8th, 2019 NASA’s Dragonfly Program: Commercialized Robotics - Enabling a New Generation of Evolvable, Resilient Assets in Orbit John Lymer Maxar† Abstract Commercialized, affordable robotics for in-space assembly of large platforms and structures are being prepared for flight in 2021. Integrating easily with standard GEO and LEO satellite command and control architectures, these automation systems enable a new operating paradigm for on-orbit assets – one that includes incremental growth, on-demand payload refresh to match user needs, and in-situ warehousing for rapid expansion, augmentation, or dispersion on a timeline independent of launch. Introduction The Dragonfly Robotic System, developed first as a DARPA seedling and then maturing through the NASA Tipping Point Program, successfully completed a ground demonstration in late 2017, shown in Figure 1 assembling a Ka band antenna. Critical Design Review occurred in 2018. Ultra-lightweight and affordable, the Dragonfly Robotic System is designed to fit into existing satellite command and data handling (C&DH) subsystems and low rate command/telemetry links for inexpensive integration – it behaves like any other satellite subsystem. The supervised autonomy operating concept facilitates command and control from a standard Mission Operations Center. Current satellite operations personnel can plan and execute robotic operations with only minor additional training. Dragonfly represents the first ‘commercialized’ robotic system – affordable and accessible to satellite owners without the risk of infrastructure changes. † The operations of DigitalGlobe, SSL and Radiant Solutions were unified under the Maxar brand in February. MDA continues to operate as an independent business unit within the Maxar organization. -

Selection and Characteristics of the Dragonfly Landing Site Near Selk

These include arrival geometry and aerodynamic/ aerothermodynamic considerations, illumination, and Earth visibility, as well as the likely presence of exposed deposits of water-rich material, potentially including materials where molten ice has interacted with organics. Cassini observations of Selk are summarized and interpreted: near-infrared reflectance and microwave emission data indicate water-rich materials in and around the crater. Radar topography data shows the rim of Selk to have slopes on multi-km scales reaching only ∼2° degrees, an order of magnitude shallower than early photoclinometric estimates. -

RESULTS IN BRIEF NASA’s Planetary Science Portfolio NASA Office of Inspector General Office of Audits September 16, 2020 IG-20-023 (A-19-013-00) WHY WE PERFORMED THIS AUDIT NASA’s Planetary Science Division (PSD) is responsible for a portfolio of spacecraft, including orbiters, landers, rovers, and probes, that seek to advance our understanding of the solar system by exploring the Earth’s Moon, other planets and their moons, asteroids and comets, and the icy bodies beyond Pluto. Currently, the planetary science portfolio consists of 30 space flight missions in various stages of operation. PSD missions fall under three categories: Discovery (small-class missions with development costs capped at $500 million); New Frontiers (medium-class missions with estimated development costs under $1 billion); and Flagship (large-class missions costing several billion dollars). With a proposed budget averaging $2.8 billion annually for the next 5 years, PSD is forecasted to maintain the largest budget of the six divisions within NASA’s Science Mission Directorate while supporting a wide range of exploration and research activities recommended by the National Academies of Sciences, Engineering, and Medicine (National Academies) or mandated by Congress.
