Abstract
A key objective of the NASA exploration missions is to explore the Solar System and beyond in an implementation that is safe, sustainable and affordable. One of the major enabling technologies for meeting this objective is the development of effective autonomous sampling systems for robotic in-situ analysis and scientific experiments for life and water detection as well as the potential to conduct materials characterization and mineralogy. Rapid sampling techniques with minimum deterioration of the sample and the potential to capture volatiles have long been an objective of the planetary science community. Tethered penetrator sampling whether the penetrator is driven by gravity [Jones et al. 2006], chemical means [Jones et al. 2006], mechanical springs [Backes et al. 2008] or air guns [Lorenz and Shandera 2000] has the potential to meet this objective. In this paper we present the development of a tethered harpoon sampling and sample handling system operated from an aerial platform for in-situ astrobiological investigations. The harpoon system can be driven into the sample using gravity, pyro, spring or compressed gas mechanisms and is retrieved using a spooling mechanism. The system description and preliminary test results are presented.
