France FDC: Launch Of Dial Satellite 1970

Here is a lovely FDC from France issued to commemorate the launch of Dial (Diamant Allemagne) satellite in 1970. The satellite was launched on 10th March 1970 and the stamp/FDC was issued on 28th March 1970. The Dial satellite was launched on a Diamant B launcher from Kourou into a 301 x 1631 km orbit inclined at 5.41 degrees. The German microsat was used to study the hydrogen geo-corona and the ionosphere. 

The data became difficult to intercept because of vibration damage caused during the launch. The satellite re-entered on 5th October 1978.

This beautiful FDC from France was sent to me by Jean-Michael from France.
