“…The space infrared telescope is an important application of solid-lubricated rolling bearings at cryogenic temperatures in a vacuum environment, which was launched to observe and study the origin and cosmogony of all kinds of celestial bodies such as planets, stars, and galaxies in the universe in the infrared band [155]. To effectively observe infrared targets in deep space and reduce noise during observation, it is necessary to cool the optical system of the telescope as much as possible [156][157][158][159][160][161]. The James Webb Space Telescope (JWST) of the U.S.A, launched in 2021, works at cryogenic temperatures below 50 K [155,162], representing the highest level of space infrared telescope technology, as shown in figure 7(b).…”

Tribology at cryogenic temperatures has attracted people’s attention since the 1950s with the acceleration of its applications on hi-tech equipment such as the cryogenic wind tunnel, liquid fuel rocket, space infrared telescope, superconducting device, planetary exploration, which requires solid lubrication for moving parts at low temperature down to 4 K in cryogenic liquid, gaseous or vacuum environments. Here the research progresses on cryo-tribology are reviewed. Tribological properties and mechanisms of solid lubricants listed as carbon material, molybdenum disulfide (MoS2), polymer and polymer-based composite, etc. with decreasing temperature are summarized. The friction coefficient was found to increase with decreasing temperature induced by thermally activated processes. The mechanism of transfer film formation should be noticed as a significant way to promote the tribological properties of the solid lubricant. On the other hand, applications of solid lubrication on moving parts under cryogenic conditions such as the spherical plain bearing, roller bearing are introduced. Tribological test technology of materials and bearings at cryogenic temperatures is summarized where the environmental control, motion and loading realization, as well as friction and wear measurement together at low-temperature environment result in the difficulties and challenges of the low-temperature tribotester. It is worth mentioning that novel technologies and tribotesters were developed for tribo-tests and tribological studies of solid lubricant, spherical plain bearing and roller bearing respectively by overcoming the limitation on cooling in vacuum, resolution of friction measurement, etc., and concentrating on in-situ observation of friction interface aiming to not only promote a deep understanding of friction and wear mechanism at low temperatures, but also give insights into performance of moving parts or components in cryogenic applications.

“…Schwalm, Hull and others [6][7][8][9] have discussed lessons learned from the IOS WISE and other experience for future NASA Explorer Class Missions. We summarize these below: WISE was not only a technical success, its performance and reliability was accomplished within the stringent budgets and schedules of a NASA Explorer Program.…”

By starting with established and flown hardware (high Technology Readiness Level (TRL)), and implementing a concurrent engineering environment and seamless team, a mission architect can achieve high reliability and high performance while operating under constrained cost and short implementation schedule. We will describe methods, including those used by the telescope team on the recent Wide-field Infrared Survey Explorer (WISE) mission, to manage cost and realize aggressive schedules. These lessons may be evoked for telescopes addressing defense, security and sensing, as well as those for NASA science.

The Wide Field Infrared Survey Explorer is a NASA Medium Class Explorer mission which launched in December, 2009 to perform an all-sky survey in four infrared wavelength bands. The science payload is a cryogenically cooled infrared telescope with four 1024x1024 infrared focal plane arrays covering the wavelength range from 2.6 to 26 µm. The survey has been highly successful, with millions of images collected, and nearly daily discoveries of previously unknown astronomical objects. The WISE science payload was designed, built, and characterized by the Space Dynamics Laboratory at Utah State University.This paper provides a brief overview of the WISE science payload and its on-orbit performance and describes lessons learned from managing the design, fabrication, testing, and operation of a state-of-the-art electro-optical payload.
