“Surface Engineering and Rocket Science –Surface Engineering Solutions to Protect Spacecrafts and Ground Infrastructure Against Terrestrial and “Extraterrestrial” Harsh Environments”
Tuesday, May 13, 2025, 11:00 a.m.
Spacecrafts (rockets, probes, satellites) and ground support equipment (launch pads) are constantly exposed to harsh environments. From a corrosive and aggressive climate to high-temperature engine plumes. Launchpad infrastructure (particularly materials surfaces), must be protected to maintain the mission’s reliability and safety. Satellites and other spacecraft are exposed to even harsher environments such as ultrahigh vacuum, atomic oxygen, thermal cycles, radiation, and debris impacts.
Understanding how harsh environments affect the properties of materials and the functionality of complex mechanisms is crucial to advance space exploration and return humans to the moon and beyond. In this talk, we will discuss how these environments can be characterized, how they can affect the integrity of structural materials, and even modify tribological and corrosion mechanisms. Protective solutions based on surface engineering technologies will be presented and the importance of preparing the next generation of space materials engineers will be highlighted.
