Student Nitric Oxide Explorer (original) (raw)
- SNOE byla studentská vědecká družice, postavená a provozovaná za pomoci organizace NASA. Start se konal 26. února 1998 pomocí ze vzduchu odpalované rakety Pegasus XL. Vědecká činnost byla ukončena v září 2000. Do atmosféry vstoupila 1. prosince 2003. (cs)
- SNOE (Student Nitric Oxide Explorer), auch Explorer 72, war ein kleiner Forschungssatellit der NASA zur Erforschung der Entstehung von Stickstoffmonoxid in der Erdatmosphäre. Die wissenschaftlichen Aufgaben des SNOE-Satelliten waren eine detaillierte Studie der Variationen des Stickstoffmonoxid-(NO)-Gehalts der irdischen Thermosphäre. Der Anteil von Stickstoffmonoxid in der Hochatmosphäre ist zwar gering, aber es beeinflusst stark die Ionenzusammensetzung der Ionosphäre. Im Detail untersuchte SNOE, wie Schwankungen der solaren weichen Röntgenstrahlung Änderungen des NO-Gehalts der unteren Thermosphäre bewirken, und wie die Aurora-Aktivität Stickstoffmonoxid in den Polarregionen erzeugt.

- Student Nitric Oxide Explorer o SNOE fue el primer satélite artificial perteneciente al programa de la NASA. Fue construido por la Universidad de Colorado en Boulder y lanzado el 26 de febrero de 1998 mediante un cohete Pegasus desde a una órbita heliosincrónica. El satélite reentró en la atmósfera el 13 de diciembre de 2003. La misión de SNOE fue realizar un estudio detallado de las variaciones de óxido nítrico (NO) en la termosfera terrestre, en concreto determinar la manera en que las variaciones en el flujo de rayos X solares afectan a la densidad de NO en la termosfera inferior y determinar la manera en que la actividad auroral produce incrementos de NO en las regiones polares. La nave tenía forma hexagonal, con unos 0,9 m de altura y 1 m de diámetro y un peso de 120 kg. Se estabilizaba mediante giro (5 revoluciones por minuto) y llevaba tres instrumentos: * un espectrómetro ultravioleta para medir el óxido nítrico. * un fotómetro auroral de dos canales para medir las emisiones aurorales justo por debajo de la nave. * un fotómetro de rayos X solares de cinco canales. El satélite también portaba un receptor GPS para determinar con precisión su órbita. La operación de la nave corrió a cargo del , de la Universidad de Colorado en Boulder. (es)
- SNOE (Student Nitric Oxide Explorer) ou Explorer 72 ou STEDI-2 est un petit satellite scientifique du programme Explorer de la NASA lancé en 1998 et destiné à l'étude du monoxyde d'azote dans la thermosphère (100-200 km d'altitude). Le satellite est le premier des trois projets développés dans le cadre du (StudenT Explorer Demonstration Initiative - STEDI) financé par la NASA (4,4 millions de dollars américains). Le satellite développé par l'université du Colorado remplit ses objectifs et sa mission s'achève avec sa rentrée atmosphérique qui a lieu le 13 décembre 2003. (fr)
- Student Nitric Oxide Explorer (SNOE ("snowy"), also known as Explorer 72, STEDI-1 and UNEX-1), was a NASA small scientific satellite which studied the concentration of nitric oxide in the thermosphere. It was launched in 1998 as part of NASA's Explorer program. The satellite was the first of three missions developed within the Student Explorer Demonstration Initiative (STEDI) program funded by the NASA and managed by the Universities Space Research Association (USRA). STEDI was a pilot program to demonstrate that high-quality space science can be carried out with small, low-cost ( The satellite was developed by the University of Colorado Boulder's Laboratory for Atmospheric and Space Physics (LASP) and had met its goals by the time its mission ended with reentry in December 2003.

- Lo Student Nitric Oxide Explorer (SNOE), a volte citato anche come Explorer 72 e STEDI 1, è stato un piccolo satellite scientifico utilizzato per studiare la concentrazione del monossido di azoto nella termosfera. Il satellite è stato proposto e costruito dal dell'Università del Colorado a Boulder come una delle tre missioni sviluppate all'interno del progetto Student Explorer Demonstration Initiative (STEDI), finanziato dalla NASA. Lo SNOE, entrato a far parte del Programma Explorer, è stato lanciato nel febbraio 1998 e, dopo aver portato raggiunto gli obbiettivi prefissati, ha effettuato il proprio rientro atmosferico il 13 dicembre 2003.
