Para los amantes de los satelites

Satélite destruido tras colisionar en el espacio

´´Un satélite comercial estadounidense quedó destruido tras colisionar
en el espacio con uno ruso, un accidente particularmente raro, indicó
el miércoles la sociedad Iridium dueña del satélite estadounidense.

La empresa Iridium, con sede en Bethesda (Maryland, este), indicó
haber "perdido un satélite operacional" tras un choque el martes con
un satélite ruso fuera de servicio, en lo que consideró uno de los
mayores accidentes de este tipo en el espacio.

Este tipo de colisión a cientos de kilómetros de la Tierra
es "extremadamente raro" y "muy poco probable", señaló Iridium.

La empresa precisó que tomará "las medidas necesarias para reemplazar
el satélite dañado". Iridium, que posee una flota de 66 satélites de
telecomunicaciones, aseguró que el accidente no podría deberse a una
eventual falla de su satélite¨.

Su pérdida podría "generar una perturbación muy limitada" de las
comunicaciones, aseguró la empresa.
