The following is an excerpt.
SFI CASA´s PhD candidate Rannveig Færgestad talks about the challenges in space in a new podcast from the Technological Weekly.
The podcast from the Norwegian polytechnical magazine Technology Weekly (Teknisk Ukeblad) is available on Spotify. The topic the consequences of the rapidly growing number of satellites launched in lower earth orbit. The busy activities make orbit increasingly dangerous as colliding satellites create an enormous number of fragments – also called space debris.
UNDERSTANDING WHAT HAPPENS DURING CRASH
In other words, this is Rannveig Færgestad´s home ground. She started her doctoral journey at SFI CASA in the autumn of 2021. In the coming years, she will work on accurate and reliable modelling of debris exposure by hypervelocity. Hopefully, these models will contribute to ensuring safety and sustainability in space.
«It is only by crashing things that we understand what happens when they crash», says Rannveig Færgestad in the podcast. The PhD candidate is one of several researchers from NTNU interviewed in the podcast series from the magazine.
«EVEN THE INTERNATIONAL SPACE STATION CAN GET IN TROUBLE»
Here is a small excerpt from the introduction to the program:
«The space debris travels around the earth at speeds that, on average, are seven kilometres per second – seven times faster than a rifle bullet. Such fragments pass through most satellites. Even the International Space Station can get in trouble, even if equipped with advanced armour against such impact».
