Athena - A possible first step in a program of human Mars exploration
32nd Joint Propulsion Conference and Exhibit, 1996This paper discusses the "Athena" mission, a concept for an initial piloted mission to Mars that could be launched at low cost in the very near future. Athena is a double flyby, which uses two Mars gravity assist maneuvers to allow a round trip Mars mission to be performed with a single minimum energy trans-Mars injection burn.

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
The present aerospace engineering and science workforce is ageing. It is not clear that the US education system will produce enough qualified replacements to meet the need in the near future. Unfortunately, by the time many students get to high school, it is often too late to get them pointed toward an engineering or science career.

Abstract The question of developing a space solar power system (SSPS) remains on the agenda as long as the energy supply of our planet is not secured for at least the next century. At the present time the oil and gas prices are low enough not to alarm the responsible governmental agencies and commercial enterprises. This may change in a few decades
