En cambio, entró en la atmósfera de Marte aproximadamente 100 kilómetros (62millas) por debajo de lo que se había planeado y lo destruyó el calor. Los controladores de la misión argumentaron que la pérdida de la nave se debió a un error en la conversión de la unidad inglesas de medición a la unidad métricas en los programas de navegación.\n\n![](https://steemitimages.com/DQmPjv1X26BVNxJjjjYzYrx6kCWuWihdrj1zkpaW3Vs5XnA/image.png)\nEl satélite *Martian Climate Orbiter*\n \nImagen extraída de:https://es.wikipedia.org/wiki/Mars_Climate_Orbiter\n\nLos ingenieros de la Lockheed Martin Corporation, que destruyeron la nave espacial, especificaron su fuerza en libras, que es una unidad inglesa. Por otra parte, los científicos del laboratorio de propulsión de aeronave de la NASA supusieron que los valores de la fuerza estaban expresado en unidades métricas, como son los Newtons. Por lo común, las libras son unidades de masa. Sin embargo, cuando se expresa como unidad de fuerza, 1 lb es la fuerza debida a la tracción por la gravedad sobre un objeto que tenga esa masa. Para hacer la conversión entre libras y Newtons, se inicia con 1lb= 0,4536 kg y, a partir de la segunda ley del movimiento de Newton,\n<center>Fuerza = masa x aceleración</center>\n<center>Fuerza  = 0,4536 kg x 9.81m/s^2</center>\n<center>Fuerza = 4,45 kg m/ s^2 </center>\n<center>Fuerza = 4,45N</center>\n\nDebido a que Newton (N)=1kg m/s^2. Como consecuencia, en lugar de convertir una libra fuerza como 4,45 N, los científicos la consideraron como 1 N la fuerza del satélite, expresada en Newtons, resulta bastante menor, lo que tuvo como consecuencia una menor órbita y finalmente la destrucción de la nave espacial. Al comentar sobre el fracaso de la misión de Marte, un científico dijo: “debemos enfatizar en el estudio del sistema métrico en los cursos de ciencia en la escuela primaria, secundaria y en las preparatorias, hasta el final del mundo.”\n\n<center>Bibliografía</center>\nChang, R. y College, W (2002).Química (7ma Edición).
