    Citation Excerpt :

    The Phobos-1/2 and Phobos-Grunt probes were designed to deploy landers and to land itself onto the Phobos surface, respectively, although all of them failed. The Phobos-1/2 probes both carried a small long-duration automatic subprobe that would land after being released by the orbiter at an altitude of 50 m [126]. To address the low gravitational field, a harpoon-like device would be fired to penetrate the surface to anchor the subprobe, and the hold-down thrust was also employed to suppress the landing impact, as shown in Fig. 11(a).
