Dr. Nick Paschalidis is the Senior Project Scientist for Technology Advancement (Division Chief Technologist) of the Heliophysics Science Division (HSD) at NASA’s Goddard Space Flight Center. He is an experimental space scientist and electrical computer engineer with over 30 years of experience in space instrumentation including 15 years in Technical Management. His research interests include space physics and space weather phenomena spanning from the source at the Sun to the Earth’s/Planetary Magnetospheres/Ionospheres and to the outer boundaries of the Heliosphere.
He has end-of-the-end experience in space instrumentation and missions including science objectives, measurement definition, signal-to-noise calculations, data product, test and calibration; he has experience in instrument development and flight built including electrical, mechanical, structural, thermal analysis and environmental testing. More specifically he has expertise in foil/MCP/SSD based charged and neutral particle instruments in the energy range 0.1eV to >100MeV including, sensor design, electrostatic optics, FEEs, electronics; special enabling subsystems such as solar-blind / solar-wind blind detectors, rad hard mixed signal ASICs, TOF x Energy x Delay Line Anode read outs, fast time / position (anti) coincidence, and mixed high voltage low voltage systems.
Recent instrument developments include Low/High energy ENAs for magnetospheric imaging and atmospheric escape, Solar ENAs for SEP acceleration, supra thermal ion / electron energy spectrometer for auroral precipitation, and mini-INMS and Ion Drift / Neutral Wind for the VLEO environment.
Currently he is the PI of STORIE/RENA Energetic Neutral Atom imager instrument, scheduled for launch to the ISS in 2026.
Dr Paschalis pioneered in a family of Rad Hard TOF and Energy ASIC microchips and contributed TOF x Energy x Delay Line Anode Position and sensor read out flight hardware on instruments and spacecraft in major missions across the solar system: NASA/Gateway/Hermes, NASA/PARKER SOLAR PROBE, ESA/SOLAR ORBITER, ESA/JAXA/BepiColombo, ESA/JUICE, NASA/MMS, NASA/VAN ALLEN PROBES, NASA/JUNO, NASA/PLUTO NEW HORIZONS, NASA/STEREO, NASA/IBEX, NASA/MESSENGER, NASA/IMAGE and NASA/CASSINI.

He is a member of NASA/GSFC’s Strategic Focus Area core team.
Current Projects
Instrument Principal Investigator for the Ring Current ENA (RENA) Energetic Neutral Atom particle instrument of the Storm Time O+ Ring current Imaging Evolution (STORIE) mission to be launched to ISS in 2026. RENA is a high sensitivity (GF ~1cm2.sr) ENA H, O composition imager in the energy range <1KeV-200KeV, FOV 4deg x 92 deg, angular resolution 4x4 deg. The instrument is based on HV charged particle rejection, electrostatic optics, multi-Foil/MCP/TOF/Delay Line Position sensing, special UV filter and tight quad time/position coincidence for UV/penetrators noise rejection. Through the motion of the ISS the instrument makes global line-of-site magnetospheric ENA images of the ring current probing, the magnetotail and the dayside magneto sheath. Forward modeling and inversion techniques are used for ring current and global plasma parameter extractions. Key for accurate inversion is the direct measurement of Earth’s Geocorona and neutral Hydrogen exosphere by NASA’s Carruthers Geocorona Observatory. Also, real time space weather nowcasting / forecasting is possible, incorporating the ENA images, as well as the upstream solar wind drivers (speed, density, temperature, B field) and the geocorona H measurements, into properly trained AI/ML models.
Mini Ion and Neutral Mass Spectrometer (mini-INMS), 1.5U volume, mass range 1-40amu Technology demonstration through the Exocube, Dellingr and DIONE CubeSat missions.
Complete Mini-INMS/Ion Drift / Neutral Wind instrument compo optimized for VLEO measures composition, density, temperature, ion drifts and neutral winds. Technology demonstration constellation mission.
Low energy 5-5000eV ENA H, O instrument based on smooth conversion surface ionization, ESA energy analysis and foil/mcp/TOF/time-position coincidence. The instrument was technology demonstrated on the Visions 2 sounding rocket mission to measure atmospheric escape.
Suprathermal Ion and Electron Spectrometer in the energy range 20-200KeV electrons, 0.2-10MeV ions, 1U volume. The instrument was demonstrated on the LAMP sounding rocket to measure auroral precipitation.
X-ray imager solar UV blind / solar wind blind / energetic particle blind. Targets future HPL missions.
