Can we land on an asteroid? Landing. Asteroids are not large enough to produce significant gravity, making it difficult to land a spacecraft. This technology allowed for the orientation control and orbit control of the spacecraft that guided it to land on Ryugu. How could we redirect an asteroid? Under consideration for deflecting an asteroid […]
