12015-06-16. Исследование спутника Юпитера Ио будет стоить около 615 тыс. долл. в день.
Ответственные лица в космическом агентстве США начали проявлять активность в части разработки роботизированной миссии которая должна будет изучать спутник Юпитера Ио. Ожидаемая стоимость проекта составляет 450 млн. долл. США на разработку аппарата и около 1 млрд. долл. на весь проект, включая запуск. Денежные средства планируется взять из объемов предназначенных для финансирования программы "Новые горизонты". Однако, программа должна официально закончиться в 2022-2023 году. Поэтому уже сейчас чиновники НАСА начали производить в большом объеме слайды и презентации с целью убедить законодателей продолжить эту программу и в дальнейшем. В связи с этим, предварительные характеристики миссии могут так и остаться предварительными. В настоящее время план полета аппарата и его характеристики выглядят следующим образом:
1. Дата пуска 2021 год.
2. Время выхода на целевую орбиту 2026 год.
3. Основная цель миссии - 9 сближений с планетой на расстояние до 200 км.
4. Масса аппарата 1500 кг.
5. Сухая масса 750 кг.
6. Оснащен улучшенной двигательной установкой.
