The design, microfabrication and initial performance results of a prototype electrospray thruster with integrated individual extractor electrodes are reported in this paper. The aim was to demonstrate increased thrust with an array of emitters spraying sim ...
This paper reports on the design, fabrication and test of an integrated colloid micropropulsion system for spacecraft attitude control using the ionic liquid EMI-BF4 as fuel. The principle of operation of the thruster is identical to electrospray ionizatio ...
This paper presents a novel concept for a compact low-cost Earth sensor based on imaging atmospheric oxygen emission at 762nm using arrays of single photon avalanche diodes (SPADs). In both nighttime and daytime there is continuous emission at 762nm due to ...
MEMS-based electric propulsion (EP) presents several advantages over conventional EP approaches, including scalability, redundancy, fine thrust control, low thrust noise, and reduced operation voltage. Small spacecraft (1- 100 kg) in particular stand to be ...
