xgravler - Experimental Gravity Research with LEGO-based Robotics Onboard a Stratospheric Research Balloon
The REEL-E payload, the final implementation of the xgravler project, measures the g-forces under changing conditions in high altitude environments. For this, the payload was put into a stratospheric research balloon during a mission named H.A.L.E, organized by the University of Reno, Nevada, and sponsored by the NASA Space Grant, Energizer, LEGO and National Instruments. The balloon was launched on 29 July 2008 from the Nevada desert, close to Reno, USA, and reached an altitude of just over 99,500 ft (~30km).
Research at AIT has identified two major challenges, the limited lifetime of the ignition system and the size and volume of the electronic interface. Past projects proved that the ignition system lifetime is limited to a maximum of 15,000 cycles. Goal of the present project is to increase this to at least 250,000. The electronic components shall be implemented on a printed circuit board (PCB), which also contains up to four μPPT.
μPPT Development - Micro Pulsed Plasma Thruster Development for Micro- to Picosatellite Applications
ARC is currently developing Europe’s first micro Pulsed Plasma Thruster (μPPT) with the ultimate objective of producing a flight model which may be flown on CubeSats. CubeSats are pico - satellites with dimensions of 10 cm 3 and hence impose the most demanding mass budget.
