White Paper
NASA

This page in the NASA Public Lessons Learned System recommends that thermal vacuum tests follow dynamics ... tests (e.g. vibration testing). It provides detailed guidance and motivation for this recommendation.

This conference paper presents detailed thermal analysis and thermal environmental test planning for ... a cubesat. It's a good case-study and example report for smallsat thermal analysts and thermal test engineers. Inputs, assumptions, methods, and results are all presented in detail.

Book
George Sebestyen et al.

This book chapter, titled "Thermal Design" covers thermal design, analysis, and testing for LEO satellites. ... This includes background on the physics of heat transfer, thermal control hardware, and processes for thermal design, analysis, and testing. Note that this chapter is only 13 pages, and does not go into significant detail on any of the included topics.

Book
David Gilmore

This chapter titled "Thermal Testing" is a comprehensive reference regarding thermal testing of space ... flight hardware. The tests covered are thermal cycling (ambient pressure), thermal vacuum, thermal balance, and burn-in. It includes a description of the elements and stages of the traditional approach, environments, margins, requirements, and required equipment/facilitates.

White Paper
US Department of Defense

This handbook provides in-depth guidance on testing of space vehicles. The testing covered includes structural ... loading, thermal vacuum, thermal cycling, thermal balance, pressure testing, burn-in, random vibration, acoustic, and pyroshock - among others. This is a dated but comprehensive source of space hardware test environments and processes.

This article is a reflection on the acceptance testing performed for a 120kg small satellite. It covers ... EMC testing, vibration testing, and thermal/vacuum testing. This case study is a good resource to review before performing your own testing.

Article
Roy Chisabas et al.

Thermal-vacuum testing is critical to ensuring satellite reliability and survivability. Unfortunately, ... many thermal-vacuum chambers are much larger than necessary for small satellites, resulting in an unnecessary cost burden for developers. This paper seeks to outline the methodology for developing thermal-vacuum chambers for testing small satellites.
