This paper will discuss the development of thin-shell, nano-laminate mirror substrates that are capable of being electro-actively figured. This technology has the potential to substantially reduce the cost of space based optics by allowing replication of ultra-lightweight primary mirrors from a master precision tool.
This paper evaluates the precision control of struts of the micro-space shell structure.

We report on the development of new mobile robots for Mars exploration missions.
NASA has been commissioned to investigate the feasibility of an orbiting Space Solar Power system that is capable of generating power from space and transmitting the power to earth based rectennas.
This paper summarizes the Rover's design and performance as well as post-mission model correlation.
There are significant international efforts underway to place mobile robots (rovers) on the surface of Mars.
Evaporation rates have been measured for the metals and alloys to be used in the TEMPUS flight experiments in order to facilitate a rational assingnment of a flight sequence that will minimize the effects of particulate and cross contamination.
