Mr. Weidner has over 32 years¡¯ experience in research and development engineering. For the last 20 years, he has designed, built, tested, and delivered scientific instruments for numerous spaceflight missions. He has demonstrated the ability to lead international teams through the development of new technology for challenging environments that perform successfully on-orbit and lead to significant scientific discovery. Currently, Mr. Weidner serves as the Project Manager for the Integrated Science Investigation of the Sun (ISIS) on Solar Probe Plus (SPP) mission in which he manages instrument development effort occurring in six different US institutions. The SPP spacecraft will fly within nine radii of the surface of the Sun to discover the fundamental links between the dynamic solar atmosphere and the solar wind, the mechanisms that heat the Sun¡¯s corona and accelerate the solar wind, and the processes that energize and transport solar energetic particles. Mr. Weidner is also the SwRI lead for the Dual Ion Spectrometer which is part of the Fast Plasma Investigation for the Magnetospheric Multiscale mission (MMS). The MMS mission uses four identical spacecraft, orbiting the Earth in close formation, to make three-dimensional measurements of magnetospheric boundary regions and examine the process of magnetic reconnection. The DIS instruments were developed in Japan by ISAS and the Meisei Electric Company. The detectors for the instrument were supplied from France by IRAP. Calibration was performed at NASA¡¯s Marshall Space Flight Center. The multi-national technical effort required careful management and communication for success. Mr. Weidner serves as the Instrument Manager for the Jovian Auroral Distributions Experiment (JADE) on the Juno mission to Jupiter. JADE is a suite of electron and ion sensors that measures the full pitch angle distribution of electrons and the three-dimensional velocity-space distribution of ions in Jupiter¡¯s magnetosphere. He led a large team of 35 scientists, engineers, and technicians who designed and built this instrument. He was responsible for budget, schedule, technical leadership, and mentoring of younger staff members on this project. He coordinated the efforts of foreign and domestic subcontractors, worked with the spacecraft vendor to solve accommodation issues, and was the primary JADE point-of-contact for the Juno Payload Office at NASA¡¯s Jet Propulsion Lab. Mr. Weidner led the development of the HI Sensor for the Interstellar Boundary Explorer (IBEX) mission. The IBEX payload contains two Energetic Neutral Atom cameras which has made the first global image of the interaction between our sun¡¯s heliosphere and the local interstellar medium. As Lead Engineer for the Solar Wind Around Pluto (SWAP) Instrument that is flying on the New Horizons mission to Pluto, Mr. Weidner led a team of engineers in the development of the electro-optics, detectors, high voltage power supplies, mechanical packaging, and flight software. He designed the analog front-end electronics as well as the control board electronics and its FPGA. On NASA¡¯s Deep Impact mission to the comet Tempel I, Mr. Weidner designed the Attitude Propulsion Interface Board (APIB) that was redundantly cross-strapped on the flyby-spacecraft and monitored coarse sun sensors, drove reaction wheels, measured tank pressure, controlled hydrazine latch valves, and included a unique thruster valve drive circuit that provided step-back and hold capability to minimize power during the battery-only long burn on the impactor-spacecraft. Mr. Weidner has worked on several other spaceflight instruments. He designed the front-end electronics for the Two Wide-angle Imaging Neutral-atom Spectrometers (TWINS). This included the imaging anode, charge amplifiers, time-of-flight electronics, pulse height analysis electronics, and the digital control board and FPGA which processes events in real-time and buffers them for the CPU. He designed the analog electronics for the Ion Electron Spectrometer (IES) instrument on the European Space Agency¡¯s Rosetta Mission, which is in orbit around the comet 67P/Churyumov-Gerasimenko. He served as the Lead Electrical Engineer for the Medium Energy Neutral Atom (MENA) imager on NASA¡¯s Imager from Magnetopause to Aurora for Global Exploration (IMAGE) mission. Previously at Southwest Research Institute, Mr. Weidner has been responsible for designing electronic systems for a wide variety of instrumentation projects. He has designed, delivered, and supported ultrasonic in-service inspection equipment around the world for the nuclear power industry. Mr. Weidner designed the digital circuitry for the AUT-EDASTM channel card that integrates an analog ultrasonic instrument with digital processing and control circuits on a VME bus card. He also designed a waveform averager card that averages ultrasonic signals in real time using high-speed ECL circuits, yielding an increased signal-to-noise ratio.
