Sense making from multi-source, electro-optical, remote sensing constellations

Manuel Gonzalez-Rivero
Maxar Technologies (United States)

With 140+ petabytes of historical data holdings, 3.8 million square kilometers of daily multi-spectral collection, integration of Synthetic Aperture Radar and newly launching assets every quarter, the opportunities to develop insight from sense making technologies at Maxar are ever growing. During this discussion, we will cover the challenges of collecting, organizing, and exploiting multi source electro-optical remote sensing systems at scale using modern machine learning architectures and techniques to derive actionable insights.

Manuel Gonzalez-Rivero has spent a career exploring remote sensing, machine learning, data science and computer vision on orbital platforms. An Alum of Carnegie Mellon University he worked at General Dynamics and Lockheed Martin building real time satellite payloads, working on remote sensing at ARL-PSU, building global machine learning pipelines at Planet Labs, Orbital Insight, and Maxar Technologies. As the Sr. Director of Applied Machine Learning at Maxar, Manuel leads teams that create the production platform for analytics and the core sense making function that delivers actionable insights to customers at scale.

4:15 PM - 4:55 PM:
Freeform optics: applications and challenges

Nelson Claytor
Fresnel Technologies, Inc. (United States)

Freeform optics, generally defined as optics without an axis of rotational symmetry, can be very useful for increasing performance while reducing size, weight, and element count in optical systems. Examples will be presented, ranging from one-off astronomical telescopes to optics for high-volume consumer devices. Although they can enable systems that would not otherwise be possible, freeform optics present significant challenges to designers and manufacturers. These challenges include finding a common language for design and fabrication, fabrication techniques, and especially metrology techniques. Potential solutions to some of these challenges will be discussed.

Dr. Nelson E. Claytor is president of Fresnel Technologies, Inc., a leading designer and manufacturer of precision molded plastic optics located in Fort Worth, Texas, USA. Dr. Claytor also serves as a director of Ascentia Imaging, Inc. of Boulder, Colorado, USA, and as the founding vice president of his local Optica chapter, The Optical Society of North Texas. Dr. Claytor received his BA in Physics from the University of California at Berkeley, and his MA and PhD degrees in Physics from the University of Notre Dame. He is an SPIE Fellow and a Senior Member of Optica. In 2017 Dr. Claytor received the inaugural Legacy Award for significant contributions to the Startup Realm, presented by TechFortWorth, a technology Accelerator and Incubator in Fort Worth. He is a 2019 recipient of the Fort Worth Business Press C-Suite Award for Outstanding Leadership in the Community as a C- Level Executive. When not working on optics, he is a Motorsport Safety Foundation Level 2 certified high performance track driving instructor.

4:55 PM - 5:35 PM:
The Roman Space Telescope Observatory build, test, and verification status

Jeremy Perkins
NASA Goddard Space Flight Ctr. (United States)

The Nancy Grace Roman Space Telescope (“Roman”) was prioritized by the 2010 Decadal Survey in Astronomy & Astrophysics and is NASA’s next astrophysics flagship observatory. Launching no earlier than 2026, it will conduct several wide field and time domain surveys, as well as conduct an exoplanet census. Roman’s large field of view, agile survey capabilities, and excellent stability enable these objectives, yet present unique engineering and test challenges. Roman comprises a Spacecraft and the Integrated Payload Assembly (IPA), the latter of which includes the Optical Telescope Assembly (OTA), the primary science Wide Field Instrument, a technology demonstration Coronagraph Instrument, and the Instrument Carrier, which meters the OTA to each instrument. The Spacecraft supports the IPA and includes the Bus, Solar Array Sun Shield, Outer Barrel Assembly, and Deployable Aperture Cover. It provides all required power, attitude control, communications, data storage, and stable thermal control functions as well as shading and straylight protection across the entire field of regard. This paper presents the Observatory as it begins integration and test, as well as describes key test and verification activities.

Jeremy Perkins is an astrophysicist at NASA's Goddard Space Flight Center where he serves as the Observatory Integration and Test Scientist for the Nancy Grace Roman Space Telescope, NASA's next flagship observatory. He is also one of the co-chairs of the gamma-ray science interest group within the physics of the cosmos program at NASA. At NASA/Goddard Space Flight Center, Jeremy develops detector technologies for future gamma-ray space missions ranging from cubesats to flagship.
