Multi-spectral Images

ESAs Sentinel satellites mission is carrying a range of technologies, such as radar and multi-spectral imaging instruments for land, ocean and atmospheric monitoring. Especially Sentinel 2 (color vision) and 3 (bigger picture) brought up some beautiful insights of our planet so far.

Zachariae glacier – the shades of grey on the left side of the image depict the static landmass, while the colours on the right show changes in sea-ice type and cover between the three radar scans:

Rosetta and Philae and Comet 67P

Half a billion kilometers away, a 10 year journey found its end. Its vastly covered, therefore I will only collect the hardfacts and the best output…in any case Kudos! to science, it’s simply science finction in real life.

The Rosetta song:

Through some kind of interaction in the comet’s environment, 67P’s weak magnetic field seems to be oscillating at low frequencies (ESA/Rosetta/NavCam)
