Purpose of the flight and payload description

The HICIBAS mission was the third flight of the Strato Science 2023 campaign aimed to perform a series of experiments in a multi-instrument platform, mainly developed in Canada. At left we can see an scheme of distribution of the payloads in the gondola (click to enlarge).

It used as platform CARMENCITA a multi-payload stabilized gondola originally introduced in late 2012 by the Nacelles Pointees (Pointed Platforms) CNES team. The platform used in this flight was developed and operated by the Canadian Space Agency based on the original CNES specification. The platform was developed with several concepts in mind: modularity to allow the inclusion of several instruments devoted to the same or different research areas in one mission, reusability to overcome the difficult to adapt a platform specifically designed around an instrument to another (reducing costs and developing times), and finally cargo volume which is maximized to allow the installation of many instruments.

Onboard the gondola were installed the following instruments:

HiCIBaS acronym for High Contrast Imaging Balloon System a balloon-borne telescope whose main goal is to demonstrate the usability of high contrast imaging equipment on board a stratospheric balloon flight. The instrument was developed at the Université Laval in Québec, Canada.

RSOnar or Resident Space Object Near-space Astrometric Research a technology demonstration payload consisting of a star tracker-like, wide FOV camera combined with commercial off-the-shelf hardware to image resident space objects from the stratosphere. It was developed at the Lassonde School of Engineering of the York University.

HABLAN or High Altitude Balloon Light At Night an experiment that uses multiple colour cameras to picture a city at different viewing angles in the three RGB bands (Red, Green and Blue. The ultimate goal of the project is to provide better remote sensing data as inputs to numerical radiative transfer models. It was developed at the Département de physique, Cégep de Sherbrooke, Canada

TRASH acronym for Technologies for Recognition and Awareness of Space Debris an experiment developed at the Université Laval

BALLOONBUS a radiation detector with real-time communication developed by the INP from Bordeaux, France

Finally was also included a balloon gondola position tracking experiment aimed to show that it is possible to track a balloon payload to millimeter precision developed at the The Department of Physics, Engineering Physics & Astronomy of the Queen's University from Canada
