Abstract The paper explores the feasibility of using ballistic hopper vehicles with CO2/metal rocket engines instead of rovers in Mars missions. The hopper mission scenario involves several ballistic flights and hence visiting several sites on Mars surface.

High performance data centers use virtualization technique which enables each physical server machine to host multiple virtual machines (VMs) to achieve highly efficient resource utilization. In this paper, we propose a measurement-based approach for efficient allocation of virtualized resources in hyper-convergence environments where virtualized ...

Mars X: A Mars Mission Architecture with Lunar-Mars Synergy
AIP Conference Proceedings, 2006A human mission to Mars, if it is to be cost effective, should take maximum advantage of previous efforts at the Moon, in terms of habitats, heavy lift boosters, and vehicles. It must also make use of nuclear site power for bases. However, to make such an effort sustainable over many administrations, it should not make use of nuclear propulsion.

Expert knowledge from many disciplines is frequently embodied in stand-alone codes used to solve particular problems. Codes from various disciplines can be composed into cooperative ensembles that can answer questions larger than any solitary code can.

What is Mars? From the ancients to the present, we have imagined Mars repeatedly and studied it longingly. As scientific knowledge of Mars has changed, so has the cultural imagination of this celestial neighbors. The earth-centered beginnings of astronomy connected the blood-red planet with the God of War.
