An Application fo the Virtual Spacecraft Concept in Evaluation of the Mars Pathfinder Lander Low Gain Antenna

This paper describes a simulation designed to evaluate a communications link between the Earth and the Mars Pathfinder Lander module as it descends under a parachute through the Martian atmosphere toward the planet's surface. The link includes a transmitter and a low gain antenna on the spacecraft and a receiving antenna and receiver on the Earth as well as a simulation of the dynamics of the spacecraft.

NASA Center for Climate Simulation (NCCS) Advanced Technology AT5 Virtualized Infiniband Report

The NCCS is part of the Computational and Information Sciences and Technology Office (CISTO) of Goddard Space Flight Center's (GSFC) Sciences and Exploration Directorate. The NCCS's mission is to enable scientists to increase their understanding of the Earth, the solar system, and the universe by supplying state-of-the-art high performance computing (HPC) solutions. To accomplish this mission, the NCCS (https://www.nccs.nasa.gov) provides high performance compute engines, mass storage, and network solutions to meet the specialized needs of the Earth and space science user communities

Flying Cassini With Virtual Operations Teams

Launched on October 15, 1997, Cassini is on a 6.7 year cruise to Saturn, flying by Venus twice, the Earth, and finally Jupiter to gain enough energy to arrive at Saturn on July 1, 2004. At Saturn, Cassini's rich complement of 12 science instruments will spend four years taking observations of Saturn's rings, atmosphere, magnetosphere, icy satellites, and large moon, Titan.

High-Rate Optical Communications Links for Virtual Presence in Space

As man continues the exploration of space, either from platforms in Earth-orbit or from missions to the bodies of our solar system, there will be an on-going need to keep the public engaged in the process so that the general populace can share in the excitement of discovery and the inquisitive (professional or student) can participate in the data mining.

Virtual Reality Simulation Tour of the NASA Glenn Wind Tunnel Facility Lobby

Welcome to the Eight by six foot Supersonic Wind Tunnel Research Facility located at the NASA Glenn Research Center in Cleveland, OH. This wind tunnel complex is part of NASA's Aerosciences Evaluation and Test Capabilities (AETC) portfolio of testing facilities. Complex hosts two wind tunnels 8 x 6 for supersonic testing and the 9 x 15 for low-speed acoustic testing. Explore the lobby and view the different objects within. Once you are looking at an object you can left click for additional information. All items in lobby are interactive, and can be viewed using the arrow keys and mouse as indicated on the bottom of the video.

A Virtual Reality Planning Environment for High-Risk, High-Latency Teleoperation

In-Space Servicing, Assembly, and Manufacturing has the potential to enable larger-scale and longer-lived infrastructure projects in space. Servicing in particular has the potential to vastly increase the usable lifetimes of satellites, both newly launched and existing. However, some of these servicing tasks require delicate manipulation and, to apply to existing satellites, need to be able to operate on structures that were not designed for servicing and, in some cases, where the exact shape of the structure is not known in advance. For this reason, human-in-the-loop ground-based teleoperation is the only option for some missions. Ground-based teleoperation presents its own difficulties. In addition to the challenge of performing delicate operations in constrained spaces, communication with the servicing platform is subject to a variable time delay on the order of 2-7 seconds, and the only visual feedback comes from camera views with limited situational awareness and viewing angles.
