Network models that reflect true end-to-end architectures need to encompass terrestrial, wireless and satellite components and be highly detailed to truly represent all of the complexities in a worldwide communications network. Based on our experience as a systems integrator where we focus on end-to-end communications, systems architectures and integrated network models that reflect those architectures we have gained efficiencies and accuracy through our tools and processes. Our use of best-in-class tools including OPNET, satellite tool kit, Popkin System Architecttrade and their well known XML-friendly definitions, such as OPNET Modeler'strade data type description, or socket-based data transfer modules, such as STKtrade/Connect, enable the sharing of data between applications for more rapid development of end-to-end system architectures and a more complete system design. By sharing the results of and integrating best-in-class tools we are able to: (1) promote sharing of data; (2) enhance the fidelity of our results; and (3) allow network and application performance to be viewed in the context of the entire enterprise and its processes","PeriodicalId":117223,"journal":{"name":"2005 IEEE Aerospace Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123890629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MSL will provide a significant milestone that paves the way for future landed missions to Mars. NASA is studying options to launch MSL as early as 2009. There are three elements to the spacecraft; carrier (cruise stage), entry vehicle, and rover. The rover has a UHF proximity link as the primary path for EDL communications and may have an X-band direct-to-Earth link as a back-up. Given the importance of collecting critical event telemetry data during atmospheric entry, it is important to understand the ability of a signal link to be maintained, especially during the period near peak convective heating. The received telemetry during entry (or played back later) allows for the performance of the entry-descent-landing technologies to be assessed. These technologies include guided entry for precision landing, a new sky-crane landing system and powered descent. MSL will undergo an entry profile that may result in a potential communications blackout caused by ionized particles for short periods near peak heating. The vehicle will use UHF and possibly X-band during the entry phase. The purpose of this report is to quantify or bound the likelihood of any such blackout at UHF frequencies (401 MHz) and X-band frequencies (8.4 GHz). Two entry trajectory scenarios were evaluated: a stressful entry trajectory to quantify an upper-bound for any possible blackout period, and a nominal trajectory to quantify likelihood of blackout for such cases.","PeriodicalId":117223,"journal":{"name":"2005 IEEE Aerospace Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124912139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Muirhead","doi":"10.1109/AERO.2005.1559338","DOIUrl":"https://doi.org/10.1109/AERO.2005.1559338","url":null,"abstract":"The Mars Science Laboratory (MSL) is the next generation Mars surface exploration mission proposed to launch in 2009. MSL faces a new and complex set of planetary protection (PP) and contamination control issues. MSL will carry a scientific payload capable of making geochemical and biochemical measurements never before attempted on another planet. MSL is designed to access most of the surface of Mars at any season for as much as a full Mars year through the use of radioisotope power. The combination of the science goals, use of radioisotope power, new measurements and theories about the presence of ice, and the requirement to evaluate off-nominal landings have forced the MSL project to develop a new approach to PP. Well, not so new, the project's strategy is the go back to the Viking probabilistic approach as the basis for its planetary protection categorization request. With the newest knowledge of Mars and detailed failure scenarios the project is preparing a very detailed set of analyses to show there is an acceptably low probability of contaminating Mars in the event an off-nominal landing. This paper discusses the formulation of the probabilistic approach and the latest results. Included is a summary of the various analyses that are required to support the probabilistic analysis including: entry and aerothermal breakup, terminal impact and breakup, thermo-fluid dynamics of icy soil in the presence of a perennial heat source to create liquid water, biologic reproduction potential and redistribution. This work is being closely coordinated with the NASA Planetary Protection Officer and is recognized as path finding for future Mars surface missions.","PeriodicalId":117223,"journal":{"name":"2005 IEEE Aerospace Conference","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127017065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
