Currently in the United States there is increasing commercial and
governmental interest in Hall-effect thrusters for high power applications. Of the Hall-effect
thrusters configurations available, it has been observed that Nested channel Hall thrusters
(NHT) are well suited to high power applications. The proof of concept work of Liang on the
X2 NHT has shown that such a configuration meets or exceeds the performance of
conventional single-channel thrusters. In order to extend the NHT concept to higher
operating powers with a wider throttling range, the Plasmadynamics and Electric
Propulsion Laboratory at the University of Michigan, with the support of the United States
Air Force Office of Scientific Research and NASA, is developing a 100-kW class laboratorymodel
NHT. The motivation and heritage of this thruster, along with the necessary
preparations undertaken to test such a device are discussed in this paper.
The development of NASA’s Kilopower fission reactor is taking large strides toward flight development with several successful tests completed during its technology demonstration trials. The Kilopower reactors are designed to provide 1-10 kW of electrical power to a spacecraft or lander,
which could be used for additional science instruments, the ability to power electric propulsion systems, or support human exploration on another planet.
Москва. 17 марта. INTERFAX.RU - Глава "Роскосмоса" Дмитрий Рогозин после отказа Европейского космического агентства (ЕКА) от сотрудничества по миссии ExoMars заявил, что госкорпорация через несколько лет сможет провести марсианскую миссию самостоятельно.
"Да, мы потеряем несколько лет, но мы повторим наш посадочный модуль, обеспечим его ракетой-носителем "Ангара" и с нового стартового комплекса космодрома "Восточный" проведем самостоятельно эту исследовательскую экспедицию", - сообщил Рогозин в телеграм-канале.
