Спутник ДЗЗ. Cryosat. [Редактировать]

Программа Европейского космического агентства по мониторингу состояния толщины и площади покрытия полярных льдов. Это позволит предсказать повышение уровня мирового океана. Для этого используются одноименные спутники на низких околоземных орбитах. Аппарат был потерян во время неудачного запуска в 2005 году.
