Current Status of Rocket Developments in Universities -Development of a Small Hybrid Rocket with a Swirling Oxidizer Flow Type Engine [PDF]

open access: yes
To develop an experimental small hybrid rocket with a swirling gaseous oxygen flow type engine, we made a flight model engine. Burning tests of the engine showed that a maximum thrust of 692 N and a specific impulse of 263 s (at sea level) were achieved.

MP‐DualNet: A Dual‐Branch Deep Learning Approach for Magnetopause Boundary Detection Using Simulated SXI Images

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract The Earth's magnetopause is a key boundary governing solar wind–magnetosphere coupling. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission will provide global soft X‐ray imaging of the magnetosphere through solar wind charge exchange (SWCX) emission, offering a new opportunity for remote sensing of magnetopause dynamics ...
