The mission, known as ISHTAR (Internal Structure High-resolution Tomography by Asteroid Rendezvous), could provide vital information needed to develop strategies to protect the Earth from asteroid threat. Mission scientists believe the relatively lightweight 420kg satellite will be able to provide answers to key questions about these mysterious objects that have a long history of interaction with planet Earth.
The ISHTAR satellite will be the first to probe the interior of an asteroid whilst also studying surface properties like depth of regolith, surface geology and spin. Paolo D'Arrigo, Space Science Mission Engineer at Astrium told the NEO Information Centre, �We are excited about ISHTAR because it is the first NEO mission concept to not only visit 2 asteroids, but to look inside using radar technology.�
The mission is designed to characterise all the physical parameters of an asteroid that are key to assessing its impact hazard and develop strategies for deflecting or destroying it. �Understanding the interior make-up of Near Earth Asteroids is an essential first step in any future strategy to mitigate the danger to Earth�, said Paolo. �Depending on whether an asteroid is solid rock or loose rubble, you could make the situation worse if you used the wrong technique.�
