Requirements and potential for enhanced EVA information interfaces
NASA has long recognized the advantages of providing improved information interfaces to EVA astronauts and has pursued this goal through a number of development programs over the past decade. None of these activities or parallel efforts in industry and academia has so far resulted in the development of an operational system to replace or augment the current extravehicular mobility unit (EMU) Display and Controls Module (DCM) display and cuff checklist. Recent advances in display, communications, and information processing technologies offer exciting new opportunities for EVA information interfaces that can better serve the needs of a variety of NASA missions. Hamilton Sundstrand Space Systems International (HSSSI) has been collaborating with Simon Fraser University and others on the NASA Haughton Mars Project and with researchers at the Massachusetts Institute of Technology (MIT), Boeing, and Symbol Technologies in investigating these possibilities. The objectives of this research so far have been to better understand the ways in which an improved information interface may be applied in a variety of mission settings and to refine the definition of system design requirements to best support those applications. Research efforts have combined the results of concept definition and mission requirements studies with experiments in pressurized spacesuits in the laboratory and in lower fidelity test-beds in field settings. Several promising approaches for the integration of highly capable information interfaces with EVA systems have evolved and have been evaluated in preliminary proof-of-concept tests. The results show considerable promise that an advanced information interface could be adapted to support near-term orbital EVA missions and could be evolved to provide robust support for future planetary exploration missions.

FRISBEE - A platform for a small satellite science swarms
, Pages: 3671-3678The FRISBEE multi-mission platform is presented, alongside the mission concept for SWARM (Space Weather Advanced Research Mission), a fleet of 30 or more microsatellites launched in groups of 5 and covering a range of local times and inclinations. The aim of this mission is to develop an understanding of the dynamic, global, and multiscale solar terrestrial interactions. The scientific payload is restricted to a dc magnetometer and electrostatic charged particle (ion and electron) analyser, providing both high time resolution and characterisation of collisionless plasma processes, together with a miniaturised radiation environment monitor, CEDEX-2, to measure total-ionising radiation dose and the higher energy protons and heavy ions associated with single-event-effect activity. The baseline satellite swarm can be launched in a variety of configurations and be augmented by future launches of identical satellites to provide greater coverage and density of measurement. The satellites require only loose formation control to ensure equal separation throughout the set of orbits defined in this document. The individual satellites are spin stabilized and each have a mass < 25 kg.

On the time variability of the net ocean-to-atmosphere heat flux in midlatitudes with application to the North Atlantic basin
, Quarterly Journal of the Royal Meteorological Society, Vol: 129, Pages: 2867-2878, ISSN: 0035-9009A new diagnostic to investigate the role of ocean dynamics in midlatitude air-sea interactions is presented and tested against observations. It is based on the analysis of the time variability of the net ocean-to-atmosphere heat flux (FS). A hierarchy of air-sea interaction models indicate that, in the absence of ocean dynamics, the power spectrum of FS should be blue at time-scales longer than a threshold set by the late-winter mean mixed-layer thickness and the sensitivity of FS to sea surface temperature anomalies. Comparison of the predicted FS spectrum with observations over the North Atlantic shows a good agreement over the subpolar gyre where the deep ocean mixed layer combined with strong stochastic forcing allows large fluctuations in FS at decadal and longer time-scales. Discrepancies, however, arise over the Gulf Stream extension region. Here it is suggested that the observed variability of FS at time-scales longer than a decade is controlled by geostrophic ocean dynamics rather than local atmospheric forcing. The diagnostic appears to be a useful and simple tool to investigate the role of ocean dynamics in the upper-ocean heat budget. It is particularly well suited to the analysis of long simulations of coupled ocean-atmosphere models. One implication of the study for ocean-only numerical simulations is that one cannot specify externally the low-frequency variability of FS. The latter should only arise as a consequence of ocean dynamics.

Simulations of the effects of interannual and decadal variability on the clear-sky outgoing long-wave radiation spectrum
, Quarterly Journal of the Royal Meteorological Society, Vol: 129, Pages: 2971-2988, ISSN: 0035-9009Using atmospheric profiles derived from the Hadley Centre atmosphere climate model version 3 (HadAM3) as input to a radiative transfer code, the sensitivity of the resolved spectrum of clear-sky outgoing long-wave radiation to both interannual and longer-term atmospheric variability has been analysed. A comparison of the simulated spectra with available observations from two satellite-based instruments indicates a reasonable match, although consistent differences are present. These may be explained by a combination of uncertainties in the atmospheric state, and in the relative calibration of the two instruments. Focusing on the simulations: if HadAM3 is forced by the observed sea surface temperature (SST) record alone, and long-term alterations in the well-mixed greenhouse gases are imposed in the radiance simulations, the changes seen within the major absorption bands are robust. Under a second scenario, where the effects of solar variability, volcanic aerosol, ozone changes and increases in the well-mixed greenhouse gases are also included in the forcing of HadAM3, the long-term profile changes tend to show an enhanced upper-tropospheric warming and low/mid-stratospheric cooling, with increased near-surface humidities compared to the SST-only case. However, the tropospheric response of the system, manifested in the spectral change pattern over the atmospheric window and water vapour bands, falls within the range of year-to-year variability.
