Looking to the Stars: Lessons from Asbestos in Space Exploration

Share this post

The history of space exploration is a tale of human innovation and technological leaps. Yet, amid the triumphs and achievements, lies a less discussed aspect: the use of asbestos in spacecraft construction. Asbestos, celebrated for its insulation and heat-resistant properties, played a significant role in early space missions. However, this seemingly miraculous material brought with it a hidden danger for the health of astronauts.

In the early days of space exploration, spacecraft designers sought materials that could withstand the extreme conditions of space travel. Asbestos emerged as a prime candidate due to its exceptional heat resistance and insulating capabilities. The lightweight and fire-resistant nature of asbestos made it an attractive choice for lining the interiors of spacecraft, protecting them from the searing temperatures experienced during re-entry into Earth’s atmosphere.


As spacecraft designs evolved, asbestos found its place in various components of spacecraft. It was used to insulate fuel tanks, protect against heat during launch and re-entry, and line the walls of the capsules and modules. A notable example is the Apollo command module, which featured asbestos insulation to shield astronauts from the intense heat generated by atmospheric re-entry.

The use of asbestos came with significant trade-offs: health risks for astronauts. Prolonged exposure to the disturbed asbestos fibers puts astronauts at high risk for asbestos-related diseases such as mesothelioma and lung cancer. As awareness of the health risks associated with asbestos exposure grew, the space industry began to reconsider its use.

In recent years, advancement in materials science and engineering have led to the development of safer alternatives to asbestos. New materials that offer comparable insulation and heat resistant properties without the negative associated health risks have come to replace asbestos in spacecraft construction.


The story of asbestos is space exploration serves as an important reminder of the delicate balance between innovation and safety. Asbestos played a vital role in protecting astronauts from the harsh realities of space travel, but also came with long-term risks. Astronauts effected by asbestos join a number of other trades who have a higher risk for asbestos exposure.
