"O Analisador de G\u00E1s T\u00E9rmico e Expandido (em ingl\u00EAs: Thermal and Evolved Gas Analyzer), ou simplesmente TEGA, \u00E9 um instrumento cient\u00EDfico a bordo da sonda espacial Phoenix, enviada ao planeta Marte em agosto de 2007. O design do TEGA \u2013 assim como de outros instrumentos \u2013 foi elaborado a partir da experi\u00EAncia obtida com a miss\u00E3o Mars Polar Lander, que falhou. Amostras do solo marciano retiradas pelo bra\u00E7o rob\u00F3tico da sonda s\u00E3o eventualmente transferidos ao TEGA, onde s\u00E3o aquecidos num forno a temperaturas de 1.000 \u00B0C. Este calor libera os compostos mais vol\u00E1teis, fazendo com que esses gases passem por uma an\u00E1lise num espectr\u00F4metro de massa. Ou seja, permite que sejam analisados os diferentes componentes qu\u00EDmicos presentes no solo, em busca de \u00E1gua, compostos org\u00E2nicos, e outros compostos \u00E0 base de carbono. A miss\u00E3o Phoenix durou at\u00E9 o dia 10 de Novembro, quando a sonda perdeu comunica\u00E7\u00E3o com a Terra. Com um prazo de atua\u00E7\u00E3o maior do que o planejado, a Phoenix, e em especial o TEGA, tiveram papel desmitificador sobre Marte: \"A miss\u00E3o da sonda foi n\u00E3o s\u00F3 estudar o solo marciano, e sim determinar se o planeta \u00E9 habit\u00E1vel.\""@pt . . . .
