This image is the first data sent to Earth by the MIRAS instrument on ESA's SMOS satellite, launched on 2 November. It was acquired as part of the initial functional verification test since the instrument was switched on on Tuesday.
The image depicts non-calibrated brightness temperature values colour coded from blue (low) to red (high). Although the image content cannot be interpreted at this time, it proves that the instrument is in good shape and the data reception and processing chain are working.
The switching-on of MIRAS (Microwave Imaging Radiometer using Aperture Synthesis), an L-band radiometer with 69 receivers mounted on a star-shaped three-armed antenna, marked the completion of the critical launch and early orbit phase.
Engineers are now evaluating the quality of the downlinked data and concentrating on the calibration of the instrument. Once calibration has been achieved, the first maps of soil moisture and ocean salinity will be released.

SMOS satellite instrument comes alive
The MIRAS instrument on ESA's SMOS satellite, launched earlier this month, has been switched on and is operating normally. MIRAS will map soil moisture and ocean salinity to improve our understanding of the role these two key variables play in regulating Earth’s water cycle.
SMOS forms three-pointed star in the sky
Following the launch of ESA’s SMOS satellite on 2 November, the French space agency CNES, which is responsible for operating the satellite, has confirmed that the instrument’s three antenna arms have deployed as planned, and that the instrument is in good health.
Two new ESA satellites successfully lofted into orbit
ESA PR 28-2009. The second satellite in ESA’s Earth Explorer series – the Soil Moisture and Ocean Salinity (SMOS) mission – and the second demonstration satellite under ESA’s Project for Onboard Autonomy (Proba-2) were launched into orbit last night from northern Russia.
