He also has served as the Deputy Project Manager on the EOS Chemistry and Special Flights Project, and as the Earth Systems Science Pathfinder (ESSP) Project Manager where he led the definition, development and implementation of the ESSP program. He then served as the Earth Explorers Program Manager where he managed the development, launch and operations of ESSP and Earth Explorer missions; QuickScat, GRACE, SORCE, QuikTOMS, CALIPSO and CloudSat.

In 2003 Mr. Chrissotimos was appointed as the STEREO Project Manager where he led the project to a successful launch in October 2006. In addition, at that time he was serving as the Deputy Program Manager for the Sun Earth Connection Programs where he was the Living With a Star (LWS) Program Manager responsible for the SDO and Geospace missions.

He recently served as the Associate Director of Flight Projects for the Exploration and Space Communications Projects Division. There he was responsible for the Lunar Reconnaissance Orbiter (LRO) Project, TDRS Project, Space Network and Ground Network Projects and GSFC Constellation Program support.

Mr. Chrissotimos is a recipient of the Meritorious Presidential Rank Award, the NASA Medal for Outstanding Leadership, and Goddard’s Exceptional Achievement Award.

Michael Delmont
Deputy Program Manager for Living With a Star and Solar Terrestrial Probes

Mr. Delmont has over 20 years supporting GFSC Missions. He most recently served as the Chief of the Mission Support Division, which provides direct support to the GSFC projects in the areas of System Safety, Reliability and Quality Assurance from design through flight operations with the objective of assuring and measuring the reliability of the system.

In 2001, Mr. Delmont was appointed as the Deputy Project Manager for the STEREO mission at GSFC. His primary duties included managing the instrument development, and leading the risk management process and launch site processing.

Mr. Delmont supported various in-house missions at GSFC including: Diffuse X-Ray Spectrometer, Extreme Ultraviolet Explorer, Rossi X-ray Timing Explorer and Wilkinson Microwave Anisotropy Probe. He also served as the Agency Program Manager for Workmanship.

Prior to his work at GSFC, Mr. Delmont performed several functions leading to the successful deployment of the mobile communication jamming system, Traffic Jam, at the US Army Harry Diamond Laboratories.

Mr. Delmont has a BS Industrial Engineering from the State University of New York at Buffalo, graduated from the US Army Product/Production Program at the School of Engineering and Logistics and has a MS in Reliability Engineering from the University of Maryland.

Mr. Delmont has received several individual and group awards while serving GSFC missions including the Exceptional Achievement Award and NASA Exceptional Service Medal.

William (Bill) Sluder
LWS Business Manager

Mr. Sluder has over 30 years of financial management and project management experience at the Goddard Space Flight Center. He joined the Explorers and Heliophysics Projects Division (EHPD) in October 2022 as the Program Business Manager for the Living With A Star and Solar Terrestrial Probes programs. Prior to that he was the Deputy Project Manager for Resources, responsible for programmatic leadership and guidance and the lead for all project planning and control functions, on the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) project. Before then, he held the same role on the Magnetic MultiScale (MMS) Project and Lunar Reconnaissance Orbiter (LRO) Project. He has also served as a Program Analyst in the Goddard CFO Program Analysis office and has held Financial Manager or Resources Analyst roles on the Robotic Lunar Exploration Program (RLEP), Landsat Data Continuity Mission (LDCM), Earth Science Data Information System (ESDIS), Hubble Space Telescope Operations & Ground System Project, and within the International Solar Terrestrial Project (ISTP) supporting the SOHO, CLUSTER and GEOTAIL missions. In addition Mr. Sluder has supported multiple proposal development efforts, source evaluation boards and ad hoc committees while at Goddard.

Mr. Sluder came to NASA in 1990 after completing a Bachelor of Science degree in Business Administration (Finance and Economics concentrations) from Towson State University.

Joe Burt
Deputy Program Technical Manager

Mr. Burt has been at Goddard for over 34 years. He assumed the position of Deputy Program Manager Technical when Explorers, Solar Terrestrial Probes (STP), and Living With a Star (LWS) began merging in 2007. EHPD has since launched 11 missions and currently has 8 more missions in development.

Mr. Burt began his career in the electrical integration and test branch by developing the Cosmic Background Explorer (COBE) command and telemetry electrical ground support equipment. He then developed the Small Explorer (SMEX) Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) command and data handling system; pioneering the first MIL-STD-1773 fiber optic data bus in space. Later he developed avionics for multiple Space Shuttle flight experiments. Mr. Burt served as the Small Explorer Program systems engineer and eventually the Transition Region And Coronal Explorer (TRACE) mission systems engineer, where the first version of the Integrated Test and Operations System (ITOS) was introduced. Next he served as the Instrument Systems Engineering Branch Head at Goddard before returning as the Mission Systems Engineer (MSE) for the James Webb Space Telescope (JWST) for six years. Then he served as the Robotic Lunar Exploration Program Office Systems Architect where the Lunar Reconnaissance Orbiter (LRO) was conceived. Additionally, he served as the capture manager for Lunar Explorer (LEx); Goddard's first Lunar Lander proposal followed by a Mars Lander proposal. Mr. Burt was also the Mission Systems Engineering lead for the Heliophysics Projects Division, before it merged into EHPD, where he chaired the Inflatable Re-entry Vehicle Experiment (IRVE) Mishap Investigation Board. Mr. Burt was also responsible for reviving the Triana/DSCOVR Mission spacecraft which launched in 2015.
