Advanced Spacecraft Technology Program

nsight is given into the APL Space Department’s Advanced Technology Development Program for spacecraft. After 40 years in the business of developing spacecraft, new technology and new methods entailing risk are still the lifeblood of the Laboratory’s contributions to the national space program. Today’s political environment concerning the use of new techniques in spacecraft and how we have come...

Spacecraft instrument technology and cosmochemistry.

Measurements by instruments on spacecraft have significantly advanced cosmochemistry. Spacecraft missions impose serious limitations on instrument volume, mass, and power, so adaptation of laboratory instruments drives technology. We describe three examples of flight instruments that collected cosmochemical data. Element analyses by Alpha Particle X-ray Spectrometers on the Mars Exploration Rov...

A Decade of Advancements in Spacecraft Communications Technology at APL

he past decade has seen a rapid transition of new spacecraft communications technology into fl ight programs at APL. Key technologies have been transitioned from concept to fl ight implementation on a timescale as short as 4 years, resulting in considerable benefi ts to fl ight missions. The science return of the MESSENGER mission to Mercury has been doubled through the infusion of circularly p...

Application of an Incremental Evolution Technique to Spacecraft Design Optimization

Based on the intuition that it is often easier to learn to solve difficult problems after similar, simpler problems have been learned, incremental evolution is a recently proposed extension to evolutionary algorithms in which the evaluation function against which a population is evolved is scaled over time. This paper presents an application of incremental evolution to the problem of physical d...
