Full title and description

ISO/TS 22295:2021 — Space environment (natural and artificial) — Modelling of space environment impact on nanostructured materials — General principles. This technical specification defines general principles and a multiscale computational methodology for modelling how components of the space environment affect nanostructured materials, and it is intended as a reference for spacecraft design, lifetime forecasting, ground test planning and analysis of material-property changes during operation.

Abstract

The document addresses peculiarities of space-environment effects on nanostructured materials (materials containing structures with at least one dimension in the range 1 nm to 100 nm) and specifies methods for mathematical simulation of these processes. It emphasizes the need for multiscale simulation methods that link models operating at different time and length scales. The scope is methodological and general — it does not prescribe detailed procedures for particular materials or hardware elements but provides guidance applicable to design, testing and lifetime assessment of spacecraft materials and components.

Scope

ISO/TS 22295:2021 provides a general description of methodology for applying computer simulation methods that span different space- and time-scales to model processes occurring in nanostructured materials under space-environment impact. It covers the principal space-environment components and their interaction mechanisms with nanostructured materials (for example space radiation, atomic oxygen, hot magnetospheric plasma, thermal cycling, and impacts from meteoroids/space debris), highlights features specific to nanoscale structures, and recommends a multiscale approach for coupling models rather than prescribing material-specific engineering procedures. The document is intended as a reference for spacecraft designers, test laboratories and researchers rather than a prescriptive test method.

Key topics and requirements

• Definition and scope for "nanostructured materials" (objects with at least one dimension between about 1 nm and 100 nm) and discussion of scale-dependent behaviour.
• Overview of main space-environment components and processes relevant to materials (space radiation, atomic oxygen, plasma, thermal cycling, meteoroids/debris) and how these may differently affect nanoscale structures.
• Requirement to adopt multiscale modelling approaches that couple atomistic, mesoscopic and continuum-level simulations where appropriate.
• Guidance on selecting modelling methods, key input parameters and boundary conditions for simulations of space-environment effects on nanostructured materials.
• Recommendations on validation strategies and the use of ground-based testing to support and calibrate models.
• Use of the document as a reference framework for design, lifetime forecasting and analysis rather than a material- or mission-specific specification.

These topics and recommendations are summarized from the standard text and supporting catalogues.

Typical use and users

Engineers and materials scientists working on spacecraft materials and coatings; system and payload designers concerned with materials performance in orbit; test laboratories planning ground-based simulation or qualification tests; researchers developing nanostructured materials for space applications; and organizations performing lifetime and reliability assessments for space hardware.
