BRITE-Austria / TUGSAT-1 has travelled about 334 million km and is operating normally. Observations of the Centaurus field are under way and return science data of high relevance on a regular basis. The Centaurus field will be investigated until mid August, subsequently a new suitable target field will be selected.


29 April 2014 - Observations of Centaurus Star Field

Starting end of March 2014, BRITE-Austria is performing an observation campaign of the Centaurus field. A full frame image taken by the BRITE-Austria instrument on March 28th 2014 is shown below, depicting the 30 bright stars that are being observed. Among these are Alpha and Beta Centauri, as well as bright stars from the constellations of Lupus and Circinus.

25 February 2014 - Happy Birthday BRITE-Austria/TUGSAT-1 !

BRITE-Austria / TUGSAT-1 celebrates its first year in orbit! The spacecraft has travelled about 235 million km and is operating normally. Performance of the attitude control system is better than the specifications. Science data collection is carried out on regular basis. Until mid March, the observed target field is Orion, from then on, observation of the field of Centaurus is planned.

11 March 2013 - Current Commissioning Status

TUGSAT-1 completed its 200th orbit and traveled a distance of 9 million kilometers in Space. All sensors (sun sensors and magnetometer) and the actuators (magnetorquers and momentum wheels) were functionally tested. The attitude control system is in passive measurement mode and performance logs are continuously downloaded and evaluated. When the evaluation is completed, de-tumbling will be carried out.

5 March 2013 - Current Commissioning Status

TUGSAT-1 completed its 100th orbit and already traveled a distance of approx. 4.5 million kilometers in Space. All subsystems tested so far show excellent health status. At present the attitude control system is checked out. De-tumbling of the spacecraft is planned for the next days.

25 January 2013 - BRITE Stars

The image of the team was captured by the BRITE scientific instrument. From Left to Right: M. Unterberger (TUGraz), C. Grant (SFL), M. Chaumont (SFL), P. Romano (TUGraz). The high-accuracy photometric instrument has been designed to achieve a specific point-spread-function through defocusing. This results in the characteristic blur as seen on the image. Testing of the two BRITE spacecraft has now been completed.
