I-INSPIRE II is an Australian 2U-CubeSat designed by University of Sydney participating in the QB50 project. The QB50 project, which will demonstrate the possibility
of launching a network of 50 CubeSats built by Universities Teams all over the world as a primary payload on a low-cost launch vehicle to perform first-class science
in the largely unexplored lower thermosphere. As a payload for QB50, the satellite carries a multineedle Langmuir probe (mNLP) sampling the electron density of the
space around it. At the same time it will carry three scientific instruments to fulfill the observation in orbit. It carrries a small COTS low resolution imager, the
in-house developed NanoSpec Photonic spectrograph and a Geiger radiation counter.
