The disclosure discloses a penetrating cushion damping device comprising a penetrator, and belongs to the field of in-situ penetrating exploration of extraterrestrial celestial bodies. A magnetic conductor encloses the non-penetrating end of the penetrator, a drag plate connected to the penetrator is provided at the lower end face of the magnetic conductor, and a magnetic source structure for generating magnetic force on the magnetic conductor is provided in the non-penetrating end of the penetrator. The disclosure utilizes the penetrating cushion anti-drag mode with the drag plate and the electromagnetic structure, which is self-adaptive to the flight penetration speed and compact in structure, reduces the jump probability, and further reduces the cushion resistance after the speed is reduced. This mode is suitable for the kinetic energy penetration exploration of extraterrestrial celestial bodies with unknown terrain conditions, and takes into account the functional requirements of penetration depth and star surface retention.

An on-orbit recycling method for a buffer foam of a cargo spacecraft includes the following steps: mechanically cutting a shaped PU foam into foam micro-blocks, and putting the foam micro-blocks into a packaging bag for packaging, where the packaging bag is filled with a foaming adhesive; the foaming adhesive includes a component A and a component B, which are independently packaged in a two-component packaging bag; and the component A and the component B are separated by a film; and squeezing the film between the component A and the component B, such that the two components are fully mixed, foamed and expanded to finally burst the two-component packaging bag, where after the packaging bag is burst, the foaming adhesive expands into gaps of the foam micro-blocks; and in a microgravity state of space, the foaming adhesive expands and fills uniformly in all directions and fully infiltrates the foam micro-blocks.
