Hypervelocity impact (HVI) studies are very important for understanding space debris, and play a crucial role in current fragmentation modelling predictions. Both the number and size of orbital debris particles are inputs to different models. The int

A variety of common spacecraft thermal control materials were exposed to a laboratory test designed to simulate the effects of the low-Earth-orbital space-radiation environment. The goal of this test program was to garner performance data on the subj

M ATERIALS that reside on the exterior of a spacecraft, and are therefore unshielded, are exposed to the entire space environment. In addition to receiving a substantial dose of ionizing radiation from exposure to solar ultraviolet radiation, externa

The Materials International Space Station Experiment (MISSE) provided opportunities to study the effect of the low earth orbit space environment on materials. This paper presents observations made on optical samples flown as part of MISSE.

Multi-spectral Earth imaging sensors commonly use edge-bonded filter arrays (also known as “butcher blocks”) for spectral selection. These arrays are built from small filter “sticks” that are diced from coated wafers and then bonded together

Infrared optical systems require a range of exotic materials, many with large indices of refraction. The mismatch in the index between the optical element and the surrounding medium can result in reflection losses that approach 50%. Antireflection (A

It is well known that solar cell coverglass materials are subject to darkening, or transmission degradation, due to interaction with protons. Our recent laboratory test results have shown that the transmission of coverglasses, once contaminated with

As the power generation capability of solar cells depends strongly on the spectra of the incident light through the coverglass, there is a critical need to understand the impact of adsorbed molecular (organic) contaminants, which absorb light in the
Silicon wafers were mounted on the exterior of the International Space Station as a part of MISSE. Post-flight ellipsometry and reflectometry were employed to show that the silicon wafers gained about a 420-A-thick layer of a silica-like contaminant
