I have my own business https://choiceauto.com.ua/stmap_83yycveq.html?levitra.shallaki.betoptic.sumatriptan isotretinoin information leaflet The ejected material greatly enhances the momentum transfer, up to four times the amount, which could help the feasibility of such a project as the object does not have to be as massive to effectively push an asteroid away. The experiments testing momentum transfer revealed objects made with more porous material, such as concrete, had less momentum transfer than objects made of denser material. Researchers used an aluminum projectile that could reach speeds of 10 km/s (around 6 miles per second) and these projectiles pushed the asteroids just enough to prevent a collision with Earth. ????
