Ex-Alta 1 (QB50 CA03)

Ex-Alta 1 [University of Alberta]

Ex-Alta 1 (Experimental Albertan 1) is a Canadian 3U-CubeSat designed by the Department of Physics of the University of Alberta participating in the QB50 project.

Ex-Alta 1 carries a digital fluxgate magnetometer for the University of Alberta and the multi-Needle Langmuir Probe (mNLP) payload for QB50.

The Ex-Alta 1 Satellite has the following science objectives:

  • Serve as a platform for the In Orbit Demonstration (IOD) of a digital fluxgate magnetometer designed at the University of Alberta.
  • Address multi-point space plasma physics with data from the QB50 constellation using the Langmuir probe common payloads and the digital fluxgate magnetometer.
  • Take part in the QB-50 string-of-pearls constellation for in-situ measurements of the lower thermosphere to build an accurate model.

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.

The satellites of the QB50 constellation will be launched to the ISS in mid 2016, from where they will be deployed.
