Computational Aeroheating Predictions for Mars Lander Configurations

The proposed Mars Science Laboratory (MSL) mission is intended to deliver a large rover to the Martian surface within 10 km of the target site. This paper presents computational fluid dynamics (CFD) predictions of forebody heating rates for two MSL entry configurations with fixed aerodynamic trim tabs. Results are compared to heating on a 70-deg sphere-cone reference geometry. All three heatshi...

Mars Polar Lander Mission Distributed Operations

The Mars Polar Lander (MPL) mission was the first planetary mission to use Internet-based distributed ground operations where scientists and engineers collaborate in daily mission operations from multiple geographically distributed locations via the Internet. This paper describes the operations system, the Web Interface for Telescience (WITS), which was used by the MPL mission for Internet-base...

Analysing Rock Samples for the Mars Lander

In the near future NASA intends to explore various regions of our solar system using robotic devices such as rovers, spacecraft, airplanes, and/or balloons. Such platforms will carry imaging devices, and a variety of analytical instruments intended to evaluate the chemical and mineralogical nature of the environment(s) that they encounter. The imaging and/or spectroscopic devices will acquire t...

Homicide Inquiry Reports as Active Texts

Inquiries into adverse events make a significant contribution to the way risk is understood in modern society. Reports produced by panels of inquiry represent an important textual development, yet some aspects of such texts remain relatively underresearched. In particular, it is the manifest functions of inquiry reports that receive attention rather than their latent symbolic functions. This pa...
