Mission Objectives

The primary purpose of the Deep Space 2 mission is to demonstrate key technologies for future planetary exploration while collecting meaningful science data.

Technological Objectives

  • Demonstrate key technologies which enable future network science missions (e.g., multiple landers, penetrators, or spacecraft)

  • Demonstrate a passive atmospheric entry system.

  • Demonstrate highly integrated microelectronics which can withstand both extremely low temperatures and high decelerations.

  • Demonstrate in-situ subsurface science data acquisition

Scientific Objectives


  • Determine if ice is present below the Martian surface

  • Characterize the thermal properties of the Martian subsurface soil


  • Characterize the atmospheric density profile.

  • Characterize the hardness of the soil and possibly the presence of any layering on a scale of many inches to a few feet.
