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. -

Ralph Lorenz Johns Hopkins – Applied Physics Lab
Space phySicS Seminar Ralph Lorenz Johns Hopkins – Applied Physics Lab Sailing the Seas of Titan, Saturn's Earth-Like Moon Thursday, September 19, 2013 725 Commonwealth Ave. Refreshments at 3:30pm in CAS 500 Talk begins at 4:00pm in CAS 502 Abstract: Oceanography is no longer just an Earth Science. The ongoing NASA/ESA Cassini mission - still making exciting discoveries 10 years after its arrival in the rich Saturnian system - has found that three seas of liquid hydrocarbons adorn Saturn’s giant, frigid moon Titan. Titan was already exotic, having a thick, organic-rich atmosphere, and a diverse landscape with mountains, craters, river channels and vast fields of sand dunes, but these seas, and hundreds of lakes, present a new environment (low gravity, dense atmosphere, hydrocarbon liquid) in which to explore familiar and important physical processes such as air:sea heat and moisture exchange, wind- driven currents and waves, etc. Moreover, Titan’s seas (notably the two largest ones, Kraken Mare and Ligiea Mare, about 1000km and 400km across, respectively) offer an appealing and accessible target for future Titan exploration. This talk will review the latest findings from Cassini, and its prospects for new discoveries as we move towards Titan’s northern summer solstice in 2017, and the opportunities for future exploration which might include (as at Mars) orbiters and landers, but also vehicles that can exploit Titan’s environment such as balloons or airplanes. The most affordable near-term prospect for in-situ exploration is a capsule to float in the seas of Titan, where after splashdown it would drift in the winds to make a traverse across the sea, measuring the liquid composition and turbidity, studying conditions with cameras and meteorological instruments, and exploring the seabed with a depth sounder. -
