From March 19 to April 20, 2017, six Canadian payloads will fly on a stratospheric balloon from Alice Springs, Australia. The balloon will perform a 10-hour mission at an altitude of 36 km.
Aerosol Limb Imager Version 2 (ALI V2)
Developed by the University of Saskatchewan, ALI V2 is an atmospheric monitoring tool that can measure the concentration of aerosols—tiny dispersed particles—in the upper atmosphere using a unique optical device. The instrument is an improved version of a prototype designed and constructed by the University of Saskatchewan that was successfully deployed on a stratospheric balloon in 2014. The upgraded version of ALI can detect a wider range of optical wavelengths, allowing it to more precisely measure the size of aerosol particles. Aerosols play an important role in climate change by scattering sunlight away from the Earth. This technology could be implemented on a future satellite mission.
Imaging Fabry-Pérot Spectrometer (IFPS)
Jointly developed by York University and MPB Communications Inc., this instrument is an improved version of a technology that was successfully tested on a stratospheric balloon in 2016. It will allow the team to test the modifications made to the filter, actuators and optics in order to improve the performance of the imager for future space missions. The objectives are to obtain accurate, detailed, simultaneous, and collocated high-resolution measurements of molecular oxygen in the 20–40 km altitude range; and to simultaneously retrieve information on surface pressure, aerosols, and surface albedo from the measurements.
Optical Particle Counters (OPC) Package
The OPC package aims to sample the stratospheric air from the balloon platform and measure aerosol size and concentration. The package consists of a suite of three existing OPC instruments: Condensation Nuclei Counter, Wyoming OPC, and New OPC. The objectives are to provide validation of satellite limb scattering observations, enable synergistic and corroborative aerosol measurements for use with the Aerosol Limb Imager (ALI) measurements, and contribute to the scientific record of in-situ size-resolved stratospheric aerosol measurements to further understanding of volcanic influence and aerosol formation and transport. This project is carried out by the University of Saskatchewan, in collaboration with the University of Colorado and the University of Wyoming.
GPS and Data Logger Breadboard
The goal of this multi-purpose electronics box is to record and provide the location and attitude of the gondola during the entire flight. In addition, the instrument will monitor, through various sensors, the health of other components onboard the gondola. It includes an onboard storage capacity for telemetry data and two high-definition cameras. This instrument is an improved version of a technology developed by a group of students from École de technologie supérieure, which was successfully tested on a stratospheric balloon in 2016. Further development was carried out by the CSA.
Power Subsystem Breadboard
This modular subsystem consists of a set of Li-ion batteries and a power distribution unit. It is developed by the CSA for STRATOS flights to provide required power to payloads.
RumbleSat Art Package
As part of the RumbleSat Art in Space Mission, a University of Calgary research project, the first RumbleSat I mission payload consists of 64 small works of art. Once the payload returns to Earth, it will begin a cross-Canada tour starting on July 1, 2017, as part of the 150 Artists Celebrating Canada 150: the RumbleSat Art from the Edge of Space Exhibition.
