We discuss the various features of Earth-observing sensorWeb developed by Jet Propulsion Laboratory and Goddard Space Flight Center, which provide key science data about eruptions within hours for volcanologists around world. Onboard AI software evaluates request, orients spacecraft, operates instruments to acquire high-resolution images with hyperspectral analysis.
We describe a timeline-based scheduling algorithm developed for mission operations of the EO-1 earth observing satellite. first range operational constraints focusing on maneuver and thermal that cannot be modeled in typical planner/schedulers. then greedy heuristic compare its performance to both prior - documenting an over 50% increase scenes scheduled with estimated value millions dollars US. also relaxed optimal scheduler showing produces schedules scene count within 15% upper bound schedules.
An Autonomous Science Agent is currently flying onboard the Earth Observing One Spacecraft. This software enables spacecraft to autonomously detect and respond science events occurring on Earth. The package includes systems that perform data analysis, deliberative planning, run-time robust execution. Because of deployment a remote spacecraft, this has stringent constraints autonomy, reliability, limited computing resources. We describe how they were addressed in our agent design, validation,...
Rapid response to the onset of volcanic activity allows for early assessment hazard and risk [ Tilling , 1989]. Data from remote volcanoes in countries with poor communication infrastructure can only be obtained via sensing Harris et al. 2000]. By linking notifications ground‐based spacebased systems, these monitored when they erupt. Over last 18 months, NASA's Jet Propulsion Laboratory (JPL) has implemented a Volcano Sensor Web (VSW) which data space‐based sensors that detect current are...
Microlearning brings a number of advantages that make it an attractive tool for education. Short and clear lessons minimize the risk information overload, promote better understanding material, enable quick easy retention information. The relevance microlearning lies in its ability to respond current educational needs trends. is considered be flexible, effective innovative approach learning can successfully applied different environments, content target groups. aim research describe impact...
An Autonomous Science Agent has been flying onboard the Earth Observing One Spacecraft since 2003. This software enables spacecraft to autonomously detect and responds science events occurring on such as volcanoes, flooding, snow melt. The package includes AI-based systems that perform data analysis, deliberative planning, run-time robust execution. is in routine use fly EO-1 mission. In this paper we briefly review agent architecture discuss lessons learned from multi-year flight effort...
The proposed HyspIRI mission is evaluating a X-band Direct Broadcast capability that would enable data to be delivered ground stations virtually as it acquired. However the VSWIR and TIR instruments are expected produce over 800 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> bits per second of while approximately for ~ 80x oversubscription. In order address this throughput mismatch concept called Intelligent Payload Module (IPM)...
This article describes the Deep Space Network (DSN) scheduling engine (DSE) component of a new system being deployed for NASA's Network. The DSE provides core automation functionality network, including interpretation requirements expressed by users, their elaboration into tracking passes, and resolution conflicts constraint violations. incorporates both systematic search‐ repair‐based algorithms, used different phases purposes in overall system. It has been integrated with web application...
The Orbital Express space mission was a Defense Advanced Research Projects Agency (DARPA) lead demonstration of on-orbit satellite servicing scenarios, autonomous rendezvous, fluid transfers hydrazine propellant, and robotic arm Replacement Unit (ORU) components. Boeing's Autonomous Space Transport Robotic Operations (ASTRO) vehicle provided the to Ball Aerospace's Next Generation Serviceable Satellite (NextSat) client. For communication opportunities, operations used high-bandwidth...
