The potential for chemical evolution on Titan

Sampling of organics to determine oxygen content, extent of acetylene polymerization, existence of chiral molecules and enantiomeric excesses, and searches for specific polymer products, would be of interest in assessing how organic chemistry evolves toward biochemistry. Such efforts would require fairly sophisticated chemical analyses from landed missions. This paper examines this chemistry and the potential instruments that could distinguish chemical evolution.

NEPTUNE: an under-sea plate scale observatory

The NEPTUNE project will establish a linked array of undersea observatories on the Juan de Fuca tectonic plate. This observatory will provide a new kind of research platform for real-time, long-term, plate-scale studies in the ocean and Earth sciences.

The Sciencecraft Process

In this paper, the authors propose a new process for the development and operation of inmanned vehicles for the exploration of space. We call the vehicle Sciencecraft to distinguish it from the more traditional vehicle Spacecraft. A Sciencecraft is an integrated unit that combines science instruments, electronics, telecommunications, power, and propulsion elements into a single system.

Kuiper Express: A Sciencecraft

The Kuiper Express is a mission to achieve the first reconnaissance of one of the primitive objects in the Kuiper Belt. The Kuiper Express is a sciencecraft mission. It will be launched using a Delta vehicle and will use solar electric propulsion to shape its trajectory in the inner Solar System, while executing two Earth gravity-assist flybys.

(abstract) Sciencecraft

The technological capabilities are now at hand to design an integrated system that combines science instruments, spacecraft, and propulsion elements into a single system. The authors have called this a sciencecraft since it is intended to provide automatic scientific observations of planetary and astrophysical objects. Integration of function allows lower mass and cost and supports a short development cycle. A specific science mission is described in this paper, a flyby of Neptune, Triton, and an object in the Kuiper belt. The SCIENCECRAFT system is described. It has electric propulsion and is capable of measuring the surface constituents and morphology of objects visited and characterizing their atmospheres both in emission and adsorption (against the Sun). Miniature fields and particles experiments are incorporated that will provide interplanetary information together with details of the magnetic and electric attributes of each object. The Sciencecraft is Delta launched and has a flight time to the Kuiper belt of 7 years. The design is such that the craft functions in a largely autonomous mode to provide low cost mission operations.
