A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times the Earth's diameter, while the tail may stretch one astronomical unit. If sufficiently bright, a comet may be seen from the Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures.

The invention relates to an anchor positioning system for detecting a lander, in particular to the anchor positioning system for detecting a planetoid lander. The anchor positioning system solves the following problems of a telescopic sleeve connecting and positioning system: an anchor bill is inclined when in incidence and transverse impact load is acted on the lander, so as to damage instruments at the inner part of the lander; a moving part of a telescopic sleeve is changed in quality during the incidence, so as to cause difficulty in estimating initial emission energy. An advancing mechanism is fixedly arranged on the side face of a cable box body, a winding mechanism is fixedly arranged on a rear end cover of the cable box body, a locking and unlocking mechanism is fixedly arranged on a right shell body of the winding mechanism, a connecting rope is stored in the cable box body, one end of the connecting rope is fixed on an anchor rod pin, and the other end of the connecting ropeis fixedly connected with a winding reel. A winding motor and an unlocking motor are connected with a pin socket by a lead wire. The anchor positioning system can also be used not only for detecting the lander of a small celestial body with weak surface gravitation such as the comet and the like, but also for automatic operation of a robot in dangerous environments.

Method and apparatus for subsurface exploration
A subsurface explorer (SSX) for exploring beneath the terrestrial surface of planetary bodies such as the Earth, Mars, or comets. This exploration activity utilizes appropriate sensors and instrument to evaluate the composition, structure, mineralogy and possibly biology of the subsurface medium, as well as perhaps the ability to return samples of that medium back to the surface. The vehicle comprises an elongated skin or body having a front end and a rear end, with a nose piece at the front end for imparting force to composition material of the planetary body. Force is provided by a hammer mechanism to the back side of a nose piece from within the body of the vehicle. In the preferred embodiment, a motor spins an intermediate shaft having two non-uniform threads along with a hammer which engages these threads with two conical rollers. A brake assembly halts the rotation of the intermediate shaft, causing the conical roller to spin down the non-uniform thread to rapidly and efficiently convert the rotational kinetic energy of the hammer into translational energy.
