Sampling Mechanism for Low Gravity Bodies

In future exploration missions to low gravity bodies (e.g. a Mars moon or a near-Earth asteroid) it is planned to collect more than 100 grams of soil and return them to Earth. In previous studies several sampling tools have been proposed but there is no single sampling technology for low-gravity bodies that has been specifically conceived to provide the ability to collect material in any envisaged situation. Low gravity bodies present indeed peculiar conditions which need to be taken into account during the design and test of sampling and sample handling systems. Primarily, the very reduced gravity limits the thrust reaction capability in support to drilling operations; and, although reactions can be achieved by spacecraft anchoring or by thrust reversal, these operative conditions could limit the effectiveness of the sampling action. An alternative solution is the exploitation of the forces naturally arising from Spacecraft momentum inversion, which can be achieved by ‘touch and go’ techniques (as e.g. performed in Hayabusa mission). Although the small duration of the contact with the soil would anyhow limit the sampling depth and the collectable soil types, a properly designed sampling system would require to conclude the operation with a great effectiveness. In the last three years an ESA founded study has been carried on and a fully functional sampling mechanism for "touch and go" sampling on a low-gravity body has been selected, designed and breadboarded. Based on the results of several Proof-Of-Principle models tested on different types of specimen and after the analysis performed on a dynamic simulation model for the sampling action, a device implementing the most promising sampling technique has been designed and manufactured. It has been then tested under ambient conditions using various kinds of asteroid soil stimulants. The proposed paper will resume the key aspects and the main achievements of the study

European Seafloor Observatory Offers New Possibilities For Deep Sea Study

The Geophysical and Oceanographic Station for Abyssal Research (GEOSTAR), an autonomous seafloor observatory that collects measurements benefiting a number of disciplines during missions up to 1 year long, will begin the second phase of its first mission in 2000. The 6-8 month investigation will take place at a depth of 3400 m in the southern Tyrrhenian basin of the southern Tyrrhenian basin of the central Mediterranean. GEOSTAR was funded by the European Community (EC) for $2.4 million (U.S. dollars) in 1995 as a part of the Marine Science and Technology programme (MAST). The innovative deployment and recovery procedure GEOSTAR uses was derived from the "two-module" concept successfully applied by NASA in the Apollo and space shuttle missions, where one module performs tasks for the other, including deployment, switching on and off, performing checks and recovery. The observatory communication system, which takes advantage of satellite telemetry, and the simultaneous acquisition of a set of various measurements with a unique time reference make GEOSTAR the first fundamental element of a multiparameter ocean network. GEOSTAR's first scientific and technological mission, which took place in the summer of 1998 in the Adriatic Sea, verified the performance and reliability of the system. The mission was a success. providing 440 hours of continuous seismic magnetic and oceanographic data. Thje second phase of the mission, which was funded by the EC for$2 million (US dollars), will carry equipment for chemical, biological and isotopic analyses not used in the first phase, which will broaden the data collection effort.Published45, 48-492.5.

THE TED MODEL FOR EFFECTIVE COMMUNICATION

openLe domande alla base della seguente ricerca sono: “Perché e come è utile adottare lo stile TED ai fini della comunicazione efficace?” Nel primo capitolo della tesi vengono fornite dettagliate definizioni in merito ai concetti di comunicazione e relazione prestando particolare attenzione all’inscindibile legame presente tra le due. Nel secondo capitolo il focus riguarda le strategie e gli strumenti da conoscere e implementare per rendere la comunicazione efficace e dunque, di conseguenza, realizzare relazioni di qualità. La “cassetta degli attrezzi” proposta è stata ricavata dai suggerimenti forniti da Chris Anderson nel suo testo TED Talks, The Official TED Guide to Public Speaking, e quindi, prendendo come case study TED. Cos’è TED? Perché è diventato un format riconosciuto a livello globale? Quali sono le tecniche applicate per rendere i talk proposti incisivi? Queste sono alcune delle domande che verranno affrontate. Il terzo e ultimo capitolo riporta le interviste effettuate a organizzatori, speaker coach e speaker che hanno partecipato a eventi TEDx organizzati in Italia con l’obiettivo di arricchire l’indagine con diverse prospettive andando oltre alle sole concezioni teoriche. La metodologia adottata per la realizzazione della seguente tesi parte dallo studio della bibliografia e dagli scritti elaborati in materia. Nel terzo capitolo, affianco alla ricerca bibliografica, il lavoro si compone di un’analisi qualitativa di dati ricavati dalle interviste, di confronti tra esperti per poter osservare come le informazioni proposte nei capitoli precedenti vengano, o meno, attuate sul campo
