UniBRITE is an optical astronomy spacecraft operated by the University of Vienna as part of the BRIght Target Explorer programme.

UniBRITE-1 was manufactured by the Space Flight Laboratory (SFL) of the University of Toronto Institute for Aerospace Studies (UTIAS), based on the Generic Nanosatellite Bus, and had a mass at launch of 7 kilograms (15 lb)[2] (plus another 7 kg for the XPOD separation system).

Due to the multicolour option, geometrical and thermal effects in the analysis of the observed phenomena are separated.

[4] UniBRITE-1 will photometrically measure low-level oscillations and temperature variations in stars brighter than visual magnitude (4.0), with unprecedented precision and temporal coverage not achievable through terrestrial based methods.

[6] The NLS spacecraft were secondary payloads on the rocket, whose primary mission was to deploy the Indo-French SARAL ocean research satellite.
