In Memoriam... SONIA KEYS (1961-2018)

We are saddened to report that Sonia Keys died on 13 August 2018 at the age of 57, after a long struggle with cancer.

     Sonia worked as a commercial software developer from 1983 to 2001 and then began working with the Astronomical Society of Kansas City, specializing in the tracking of Near-Earth Objects (NEOs). Her skill and reliability with NEO astrometry caught the attention of the Minor Planet Center (MPC), and that led to a position as an astronomer and software developer for the MPC.

     As Kyle Smalley, she had served in the United States Navy's Nuclear Power Program, as an Electronics Technician and Reactor Operator aboard a submarine, and was honorably discharged in 1982. She then completed a bachelor of science degree in Mathematics and Computer Science at Central Missouri State University in 1986.

     A few years after joining the MPC, Kyle made the profoundly brave decision to live, both personally and professionally, as Sonia Keys. This quiet but solid act exemplified the way she approached her work, with conviction and resolve.

     Outside of the MPC, Sonia enjoyed programming (yes, she did it for fun!), photography and sailing on the Charles River. When weather or health conditions prevented her from sailing, she enjoyed watching televised yacht racing on the Internet.

     Sonia was the conscience of the MPC. Her clarity of thought, her willingness to ask difficult questions, and her tenacity will be sorely missed.

Welcome to the PDS Small Bodies Node

thumbnail of planetsThe Small Bodies Node (SBN), a part of NASA's Planetary Data System, specializes in the archiving, cataloging, and distributing of scientific data sets relevant to asteroids, comets and interplanetary dust.

More specifically, SBN seeks to archive data from:

NASA missions are obligated to archive their data within PDS so most of the data is related to and in support of NASA missions. Ground-based observers are not required to archive their data (because they are often funded from non-NASA/public sources) but are welcome to contribute their data.

Data Analysis Proposals Support

Proposers please note: If you are planning to use PDS data for your ROSES data analysis proposal (e.g., Discovery Data Analysis Program, Cassini Data Analysis, Lunar Data Analysis, etc), please note the archive status indicated on the top of each dataset webpage. A status of "archived" or "locally archived" indicates the data are in their final form, while "certified" indicates there are minor editing corrections still to be made. Data sets with other status levels may be either in active development, or considered to have some significant deficiency. Proposers are urged to consult the ROSES solicitation and the appendix for the Program Element to which they are proposing for the specific guidelines on the use of spacecraft data in general and data sets with known issues in particular.

Data Release Schedule

We have a data release schedule that has the proposed dates of when data provided to the SBN for archiving will be publicly available. This is a proposed schedule and users should not be surprised if missions/projects are late.
