Evaluation and Performance Optimization of a Hydrogen Peroxide-Based Green Monopropellant Thruster for Steady-State Operations

open access: yesAerospace
Hydrogen peroxide (High Test Peroxide, HTP) emerges as a promising candidate for green space propulsion applications due to its lower toxicity compared to liquid conventional propellants such as hydrazine and nitrogen tetroxide.

HAN-based monopropellant assessment for spacecraft [PDF]

open access: yes32nd Joint Propulsion Conference and Exhibit, 1996
The growing cost of space missions, the need for increased mission performance, and concerns associated with environmental issues are changing rocket design and propellant selection criteria. Whereas a propellant's performance was once defined solely in terms of specific impulse and density, now environmental safety, operability, and cost are ...

PARAS program: Phased array radio astronomy from space [PDF]

open access: yes
An orbiting radio telescope is proposed which, when operated in a Very Long Baseline Interferometry (VLBLI) scheme, would allow higher (than currently available) angular resolution and dynamic range in the maps, and the ability of observing rapidly ...
