Material science plays an absolutely critical role in space exploration. So when a new type of self-healing composite is announced, it’s worth a look–especially when the press release specifically calls out its ability to repair microtears associated with micrometeoroid impacts on satellites. It sounds like just such a composite material was recently invented at North Carolina State University - and it’s even already been spun out into a start-up company.

The 18th European Space Conference (ESC) will take place on 27 and 28 January 2026 at the Square Convention Centre in Brussels, Belgium.

Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates a ‘sky’ of raining plasma blobs that continue to fall even after the flare subsides.

To land on the right foot on the Red Planet, European engineers have been dropping a skeleton of the four-legged ExoMars descent module at various speeds and heights on simulated martian surfaces.
