Soft Landing of Spacecraft on Energy-Absorbing Self-Deployable Cushions

A report proposes the use of cold hibernated elastic memory (CHEM) foam structures to cushion impacts of small (1 to 50 kg) exploratory spacecraft on remote planets. Airbags, which are used on larger (800 to 1,000 kg) spacecraft have been found to (1) be too complex for...

Martian Landing Balls

A report describes Martian landing balls, which are under development for use in delivering scientific payloads to Mars. Martian landing balls are related to other soft-landing devices that resemble beach balls and that have been described in several previous NASA Tech Briefs articles. They are also related to the...

Mars Lander

A brief report presents drawings for the conceptual design of a spacecraft that would land on Mars or another remote planet. The spacecraft would have a tetrahedral shape, would include airbags to cushion impact, and would have a self-righting capability. The drawings show the general appearance of the spacecraft and show the...
