Resistors Suit Up For Space Travel


Hoping to explore planet Jupiter, the European Space Agency (ESA) is constructing the Jupiter Icy Moons Explorer (JUICE) spacecraft. In designing the spacecraft, ESA has selected 11 state-of-the-art instruments from science and engineering teams from all over Europe, the United States, and Japan, including USA’s Ohmcraft, a specialist in thick-film, high-voltage, high-precision resistor design and manufacturing.


The JUICE spacecraft’s UV Imaging Spectograph (UVS) instrument will employ six custom high voltage resistors from Ohmcraft. The UVS will examine the atmosphere, magnetosphere, satellites, and rings surrounding Jupiter’s moons. The instrument operates in the wavelength range of 55 nm to 210 nm with a spectral resolution of <0.6 nm. It will reach a resolution of 0.5 km (0.3 miles) observing Ganymede, and up to 250 km (155.3 miles) observing Jupiter.

In Conversation with Antonio Neri, President & CEO – Hewlett Packard Enterprise & Salil Parekh, CEO – Infosys

Hear the CEOs of Infosys & HPE discuss the current crisis and how it has accelerated the need for digital transformation for their clients. Connectivity at the Edge, right mix of hybrid cloud, ability to extract data faster than ever before… these are just some of the contributions that HPE and Infosys make to our clients’ digital transformation journey.


To ensure the resistors’ performance over more than a decade in the extreme conditions in space, Ohmcraft performed extensive testing on the resistors to meet the specific requirements of NASA’s space flight specification EEE-INST-002. For more information, visit Ohmcraft.
